Title: Method for operating driving motor of electric automobile
Inventor: WATANABE KATSUYUKI
IPC: B60L15/20
Filed: 1993-06-21
Abstract: PURPOSE:To easily shift the change gear of an electric automobile adopting a manual change gear system by generating the torque corresponding to the pressing down amount of an accelerator pedal while a clutch is engaged and making the rotating speed of a motor equal of the speed of a wheel-side clutch disc immediately before the disengagement of the clutch when the clutch is disengaged. CONSTITUTION:A controller 10 inputs the rotating speed of a motor 8 from the encoder 9 of the motor 8, signals indicating the engaging and disengaging states of a clutch 4 from the clutch 4, gear position signals G from a change gear 5, and accelerator pressing down amount signals A from an accelerator pedal 7. The controller 10 makes the motor 8 generate torques in accordance with the signals A while the clutch 4 is engaged. When the clutch 4 is disengaged, the controller 10 calculates the rotating speed of the wheel-side clutch disc 4a of the clutch 4 from the rotating speed of the motor 8 immediately before the disengagement of the clutch 4 and the change gear ratio between the new and old gear positions and controls the motor 8 so that the rotating speed of the motor 8 can become equal to the calculated rotating speed. Therefore, the gear shifting operation can be performed smoothly.

Filed: 1988-06-16
Abstract: PURPOSE:To perform quantization with an invariably constant threshold value to the surface reflectivity of a body to be read by comparing respective digital signals which are obtained by sampling a photoelectric conversion signal of one scan plural times and performing conversion by an A/D converting means and judging the surface reflectivity, and determining the corresponding threshold value. CONSTITUTION:A line sensor 13 makes a scan repeatedly at right angles to the conveyance direction (a) of postal matter P and performs photoelectric conversion and an A/D converter 15 samples the photoelectric conversion signal of one scan from an amplifier 14 plural times and converts sampled signals into digital signals. A comparative arithmetic part 20 compares those values to judge the surface reflectivity of the postal matter P, thereby determining the corresponding threshold value. Then the determined threshold value is converted into an analog signal, which is used as a threshold value to quantize the photoelectric conversion signal and the A/D conversion processing of the photoelectric conversion signal and the comparative arithmetic processing for determining the threshold value are carried out plural times in the conveyance direction of the body P to be read. Consequently, even if the surface reflectivity of the body P to be read varies, the quantization is performed with the invariably constant threshold value to the surface reflectivity.

Title: Semiconductor device
Inventor: AKASHI SHINICHI
IPC: H01L21/331
Filed: 1978-12-01
Abstract: PURPOSE:To obtain a semiconductor device appropriate to high-speed switching, without increasing the area of the semiconductor device and by providing simple wiring. CONSTITUTION:p-Type base layers 22, 22' and a biasing resistor layer 26 are made on an n-type silicon substrate 21. n-Type emitter layers 23, 23' are made. An n-type layer 23'' is produced in the layer 26. An oxide film 24 is selectively perforated to provide wiring 25, 25', 25'' to Darlington-connect two transistors to each other. As a result, a pn-junction between the layers 22, 23'' serves as a stored carrier discharging diode. Since carriers stored in the second transistor are rapidly discharged to the base 25 of the first transistor, high-speed switching can be performed. Because the diode, namely, the layer 23'' is located in the resistor layer 26 to connect the base layer 22, 22' to each other, the area of the semiconductor device is decreased. Since the area of a collector-emitter junction is greatly reduced and the diode is bonded and the capacity is decreased, the high-speed switching is enabled.

CONSTITUTION:At a point in time where discharge of air necessary for decomposing oil is terminated, power is initially supplied to a first heater of heaters 26, and oil trapped by the filter 25 thereof is decomposed by the action of a catalyst whereby a generated waste gas is forcibly discharged. When the time required for terminating the decomposition of oil, a timer is deenergized, and the power supply to the first heater is stopped. At this point in time, power supply to a second heater is started by a switching device 28, and a similar operation is carried out. A similar operation is carried out with respect to a third heater, and successively power supply and interruption thereof are carried out. In this manner, by dividing the heater 26 into a plurality of heaters and using them successively, decomposition of oil is positively carried out and contamination of the main body of a ventilation fan can be greatly reduced and cleaning thereof is almost unreguired.

Filed: 1989-06-14
Abstract: PURPOSE:To improve coverage of an Al film inside a contact hole by a method wherein the contact hole is formed after a silicide film is adhered on an interlayer insulation film and the Al film is adhered on the silicide film to form laminated Al wiring. CONSTITUTION:On an interlayer insulation film 11 of an upper layer of a MOS.FET (Q1, Q2) comprising a gate electrode 5 and semiconductor regions 8, 9, a first silicide film 12 is adhered and then a contact hole 13 reaching the n<+>-semiconductor region 9 is formed by dry etching. Then by means of sputtering, an Al film 14 is adhered on the silicide film 12. Since no silicide film 12 exists on the side wall of the contact hole 13 at this time, no migration of the Al film 14 will occur on this side wall. A second silicide film 12 is adhered on the A film 14 to form laminated Al wiring 15a by patterning. Thus coverage of the Al film 14 embedded inside the contact hole 13 is improved thereby improving reliability of the wiring.

Title: Image forming device
Inventor: SUGIKUBO TOSHIHIRO
IPC: G03G15/04
Filed: 1988-06-20
Abstract: PURPOSE:To obtain appropriate resolution to each color by properly using a laser light source and head light source by switching in accordance with the color of an image to be formed. CONSTITUTION:An exposure means has two kinds of light sources of a laser light source 3 and head light source 10 constituted of arrayed point sources 3 and controls the changeover of the light sources 3 and 10 to each other in accordance with the color of an image to be formed. Then a colored section, such as a black section which requires high resolution is exposed by using the laser light source 3. On the other hand, the image of a colored section which does not require high resolution is formed by performing exposure with the head light source 10. Moreover, since the light source 10 is positioned near an image carrier 1 and it can be considered that the position of the light source 10 does not change even after the lapse of long time,but is fixed, positioning of the image can be adjusted by means of the optical system of the light source 3 side only. Therefore, appropriate resolution can be obtained for each color.

Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To attain improvement in system performance by dynamically changing the refill size and checking a page boundary by adding a small amount of hardwares to a component originally provided with a cache controller. SOLUTION: When a cache 1 has failed, a block including a request address is first refilled, the number of effective bits in the default set refill size and the number of bits at the said address corresponding to the refill size are refilled just for the size arithmetically determined by a refill size determining circuit 4, and the refill size is dynamically changed by this operation. In addition, only when a page boundary discriminating circuit 5 discriminates the address at the time of executing refill just for the size arithmetically determined from the request address does not exceed the page boundary, is the block in the designated area in the refill size refilled from the block, including the request address.
