Toshiba is Japan's largest semiconductor manufacturer and the second - largest comprehensive electrical machinery manufacturer, belonging to the Mitsui Group. Since its founding in 1875, it has gone through a long journey of 143 years.

The Toshiba Group was founded in 1875 and is committed to striving for the future of humanity and the planet, aiming to become an enterprise group that can create rich value and contribute to the lives and cultures of all humanity. The Toshiba Group's business areas include digital products, electronic components, social infrastructure equipment, household appliances, etc. Toshiba (Toshiba) is a Japanese semiconductor manufacturer and the second - largest comprehensive electrical machinery manufacturer, belonging to the Mitsui Group. The company was founded in July 1875 and was originally named Tokyo Shibaura Electric Co., Ltd. It was formed by the merger of Tokyo Electric Co., Ltd. and Shibaura Seisakusho in 1939.

In the 1980s, Toshiba transformed from a company mainly engaged in household appliances and heavy - duty electrical machinery into a comprehensive electronic and electrical appliance company including communications and electronics. In the 1990s, Toshiba achieved rapid development in digital technology, mobile communication technology, network technology, and other fields, successfully transforming from a giant in the household appliance industry to a pioneer in the IT industry.

In 1982, Toshiba developed a W - plan, investing 34 billion yen and 1,500 technicians in the research and development and production of DRAM. In 1985, Seisaburo Saito from the semiconductor team developed the 1M DRAM with the largest global capacity at that time, and Toshiba surpassed the United States to become the world - leading semiconductor manufacturer.

In the 2000s, with the popularization of computers, the flash memory market experienced explosive growth. In 2001, the market size exceeded 9 trillion yen. In the same year, Toshiba announced the cancellation of the DRAM business division and concentrated resources on flash memory.

Although Toshiba has a long history and important position in the semiconductor field, after entering the 21st century, with the rapid development of technology and the intensification of market competition, Toshiba's market share in the semiconductor field has gradually decreased. At the same time, due to the fierce competition from international competitors in the Japanese semiconductor market, Toshiba's semiconductor business has also faced certain challenges.

However, as a company with a history of more than 140 years, Toshiba has accumulated rich experience and technology in the development process of the semiconductor field. In the future, with the continuous progress of technology and the continuous change of market demand, Toshiba will continue to be committed to the research and development and innovation of semiconductor technology to maintain its competitiveness in the global semiconductor market.

Air Conditioners
Air conditioners are major household appliances that use frequency converters for control. The frequency - conversion control of the compressor motor is achieved through the use of key semiconductor devices such as microcontrollers, insulated - gate bipolar transistors (IGBTs), and optocouplers. The microcontroller provides overall system control, pulse - width modulation (PWM) generation, and system protection functions. IGBTs and optocouplers are located in the frequency - converter drive circuit and its interface, respectively. Currently, more and more air conditioners have self - cleaning functions and vector - controlled compressor motors for energy savings. Power - factor - correction (PFC) ICs or IGBTs are used in the power circuit to keep the harmonics of the input circuit below the limits of the IEC.

Refrigerators
Using a frequency converter to drive the compressor motor has basically the same function as that of an air conditioner, but various sensors and high - end microprocessors are used for internal temperature and humidity control. Frequency conversion can achieve high efficiency (energy saving), low vibration, and low noise.Washing Machines
The latest washing machines use frequency - converter control for washing and spin - drying. Frequency - converter control helps reduce the noise and vibration of washing/spin - drying and enables the washing machine to adjust the water volume and motor torque according to the laundry load. IGBTs are used for motor driving, and microcontrollers are used for overall control. Intelligent power devices (IPDs) are used to drive the circulating water pump of the spin - dryer. Power - factor - correction (PFC) ICs or IGBTs are used in the power circuit to keep the harmonics of the input circuit below the limits of the IEC.

Induction Cookers
Induction cookers use electromagnetic heaters to directly heat cooking vessels. Generally, induction cookers can be used for baking and grilling. The heat can be adjusted from very high to very low (simmering) to achieve good cooking results. IGBTs are used for electromagnetic heaters, microcontrollers are used for temperature control, and light - sensitive thyristor - coupled devices are used for the control circuit of the cooling fan, etc. Nowadays, induction cookers that can use all - metal pots including aluminum are becoming popular. In addition, power - factor - correction (PFC) ICs or IGBTs are used in the power circuit to keep the harmonics of the input circuit below the limits of the IEC.

Electric Rice Cookers
Electric rice cookers are appliances specially developed for effectively heating the inner pot to achieve the best rice - cooking results. The electromagnetic - heating (IH) mode is common not only in Japan but also throughout Asia. Compared with non - IH electric rice cookers, the IH mode has higher thermal efficiency and lower energy consumption. Electromagnetic heating enables cooking rice with the best softness at high temperatures. IGBTs are used for electromagnetic heating, bidirectional - thyristor - output optocouplers are used to drive the pot heater. A microcontroller can control the whole, and transistors drive the cooling fan. High - end models are equipped with side heaters in addition to the bottom heater for high - energy heating. Some models also have top - heating coils to prevent water droplets from forming on the lid in the keep - warm mode; IGBTs are used to switch the heating coils.

Dishwashers
Frequency - converter motors can generate powerful water jets while achieving low vibration and low noise. IGBTs are used for motor driving, and microcontrollers are used for overall control. Bidirectional thyristors and optocouplers are used to drive a heater for hot - air disinfection. Optocouplers are also used to drive water - supply and - drainage valves.

Microwave Ovens
Microwave ovens use microwave radiation to cook or heat food by moving water, fat, and sugar molecules. Recently, super - heated steam ovens have become a topic of much public discussion. Since they can remove excessive fat and salt from food, they have become popular as a healthy cooking method. IGBTs are used to drive the magnetron, microcontrollers are used to control the heating amount, optocouplers are used to drive the fan motor, and transistors are used to drive the cooling fan.

Warm - Water Cleaning Toilet Seats
The basic feature of warm - water cleaning toilet seats is that they can clean the user with a water jet while the nozzles can also clean themselves. Other advanced features include massage options achieved through the swinging and reciprocating motion of the water jet. For quickly heating the toilet seat, the energy - saving function of activating the sensor when you approach has been newly developed.

Water Heaters
Water heaters are generally classified into gas, electric, and solar water heaters. They use almost the same semiconductor devices. Hot water is circulated to bathrooms, floor - heating systems, etc. Hot water and cold water are mixed through a mixing valve and adjusted to the water temperature set by the remote controller (PLC communication). Microcontrollers are used for the control of heaters and remote controllers, and thyristors are used for PLC communication ICs and pump motors. Now, many manufacturers supply heaters known as heat - pump water heaters that adopt high - efficiency and energy - saving electric heat pumps.
