IPC: H05B6/68
Filed: 1993-06-30
Abstract: PURPOSE: To improve a manufacturing yield for a microwave oven driving system in a simple constitution by driving a microwave oven, when using either a DC power source charged in a storage battery or an AC power source, supplied through an external line. CONSTITUTION: A system controller 110 senses whether the type of a drive power source is AC or DC. Based on the result, an AC/DC sensing means 100 outputs a signal used in a microwave oven.

Abstract: PURPOSE:To improve the exhaust gas characteristic and fuel consumption by properly controlling the air-fuel ratio on the restart of fuel feed by gradually reducing the aimed air-fuel ratio to the value corresponding to the operation state, on the restart of fuel feed after the completion of the prescribed deceleration operation. CONSTITUTION:In an electronic control unit 4, the fundamental fuel quantity is obtained on the basis of the signals of an intake pipe pressure sensor 12 and an engine revolution speed sensor 14, and the correction according to the intake air temperature or cooling water temperature by the sensors 8 or 13 is applied, and an aimed air-fuel ratio is feedback-controlled on the basis of the output of an O2 sensor 1. When a prescribed deceleration operation state is judged from the signal of a throttle sensor 10, the drive of a fuel injection valve 11 is suspended, and the fuel feed into an engine 2 is suspended. When the fuel feed is restarted, the aimed air-fuel ratio of the mixed gas in an intake pipe 7 in lean state is gradually reduced to the value corresponding to the operation state, and the corresponding feedback control is carried out. Thus, the air-fuel ratio on the restart of fuel feed can be properly controlled without making the air fuel-ratio rich.

Title: Disk device
Inventor: WAKABAYASHI NORIAKI
IPC: G11B21/10
Filed: 1981-10-13
Abstract: PURPOSE:To perform stable track access by allowing a track follow-up control circuit to include a nonlinear element which improves transient settling in case of determination of phase from track access to a desired track. CONSTITUTION:A track follow-up control circuit consists of a block 21 which generates a feedback voltage regarding a position, a block 22 which generates the differentiation of the positin, i.e. a speed voltage, a block 23 which supplies a nonlinear element for the speed voltage, and an addition block 24. The gain of this block 23 is 1 in a low-speed area, but exceeds 1 at a specified speed or above. Therefore, when a head starts access at an outer track and proceeds to a desied track, the speed is high in switching from speed control over the access to track follow-up control, so the influence of the nonlinear element is exerted or increasing the gain of speed damping.

Title: Auto-white balance device
Inventor: YOSHIDA HIDEAKI
IPC: H04N9/73
Filed: 1987-06-29
Abstract: PURPOSE:To obtain the highly speedy and stable responsiveness of a gain control by providing a gain control transmitting element to transmit a color signal, the color signal integrating means of an input side and a gain holding means to keep the gain control signal of an obtained level stationary and to supply it to the gain control transmitting element. CONSTITUTION:The signal of a first field period f1 is inputted through analog switches 8 and 9 to gain control amplifiers GCA 4 and 5. In a vertical blanking period B2, when the integrating output value of R and B signals of the f1 passes through the GCAs 4 and 5, this value is feedback controlled so as to be matched to the integrating output value of a C signal. The output signal is controlled so as to be the almost same level as the output of a G signal line 2. Samely, as for an image signal after a field period f2, based on the color signal of a preceding field period, a white balance control is executed. Thus, since an delaying element is not included to a feedback loop, a response is speedy and stability is satisfactory.

Abstract: PURPOSE:To permit the application of the captioned apparatus into the equipment which receives the bad influence of magnetic material by forming one or both of the driving and trailing frictional plates from the plate members which are made of austenite steel material whose surface is applied with salt-bath nitriding treatment, thus increasing the rate of use of nonmagnetic material. CONSTITUTION:When pressurized oil is supplied through a passage 8 into a cylinder 2 formed in a driving drum 1, a piston 3 shifts in the Z direction, and a driving frictional plate 4 and a trailing frictional plate 7 are press-attached. Therefore, the power of the driving drum 1 is transmitted to an output shaft 5 through the above-described both frictional plates 4 and 7 and a clutch hub 6. In this case, one or both of the above-described frictional plates 4 and 7 are made of the austenite stainless steel material such as hot-rolled stainless steel plate, etc., and the surface is applied with the hardening treatment by the salt bath nitriding (tufftriding). Therefore, the rate of use of nonmagnetic material can be increased, maintaining the high abrasion resistance and seizureproofness, and an aimed purpose can be achieved.
