Title: Electronic control device
Inventor: TSUJII TAKAYUKI
IPC: H02J1/00
Filed: 1982-09-20
Abstract: PURPOSE:To suppress the malfunction of a system at the time of resetting, by setting forcibly an interface means which receives directly an output of a main control means, to the inactive state for a prescribed time from the time when an electric power source is turned on or the system is reset. CONSTITUTION:When an electric power source switch 3 is turned on, an electric power source for an electronic circuit, which is smoothed by a capacitor 27 through an electric power source transformer 5 and diodes 6, 7 is aroused. A constant-voltage circuit CV supplies DC constant-voltage to a main control means MCU46. Rise of power supply voltage of the MCU46 is not attained instantaneously, but a time delay is generated. On the other hand, voltage of a resetting circuit RE also rises slowly. A Zener diode 37 does not conduct until reaching breakdown voltage, and a transistor 45 remains off. Accordingly, a ground terminal 43T of a driving circuit 43 being an interface means is in a floating state, and is set forcibly to the inactive state. Therefore, a control signal of malfunction of the MCU46 is not transferred to loads 9, 16 and 20.

Inventor: YOSHIOKA MAMORU
IPC: F02B33/00
Filed: 1986-07-15
Abstract: PURPOSE:To prevent the shock, which occurs in an operating range of a large gear ratio when the operation of supercharging is switched, by selectively operating a supercharger, based on a comparison between the threshold value of the load, which is set by a supercharger-operating-range-setting-means, and the actually measured value. CONSTITUTION:A gear ratio detecting means 4 detects the gear ratio of a transmission, while a supercharger-operating-range-setting-means 5 sets the load-threshold-value at a low value for a high gear ratio but at a high value for a low gear ratio. A supercharger 6 compares this load threshold value with the actually measured load value to drive or stop a supercharger 2. Regarding the load threshold value for a low gear ratio, the ratio of the intake-air-flow to the engine revolving speed, or Q/NE, is set at 0.5(l/rev). Regarding the load threshold value for a high gear ratio, the ratio Q/NE is set at 0.4(l/rev).

Title: Developing device
Inventor: KIN HIDENORI
IPC: G03G15/08
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To form a uniform and precise image while developer is sufficiently carried by providing the surface of a developer carrier with many spherical recessed parts and specifying relation between the average diameter of the recessed part and the average grain size of the developer. SOLUTION: The developer carrier 9 is formed of a metal or resin and the surface thereof is roughened. The many spherical recessed parts of the surface of the carrier 9 are formed by using blast processing, etching processing or the like. It is preferable that the relation between the average diameter L of the spherical recessed part and the average grain size (d) of the developer 8 is d/4<=L<=8d. When the diameter L of the spherical recessed part becomes larger than 8d, the carrying quantity of the developer 8 is reduced and the desired carrying quantity is hardly obtained. Besides, fine density irregularity is caused according to the cycle of ruggedness. When the diameter L of the spherical recessed part becomes smaller than d/4, the carrying quantity of the developer 8 is increased but the electrifying quantity thereof is reduced.  This is because the contact chance of the developer 8 with the carrier 9 or a regulation member 10 is reduced when the carrying quantity thereof is increased.

Title: Mounting process for semiconductor element
Inventor: MATSUBARA YUJI
IPC: H01L21/52
Filed: 1985-07-26
Abstract: PURPOSE:To prevent any bonding from peeling off by a method wherein an inner part of a region to be coated with conductive paste in an island for mounting a semiconductor pellet is left without paste while the remaining part is coated with conductive paste to bond a semiconductor pellet thereon. CONSTITUTION:A semiconductor element (pellet) 1 is bonded on conductive paste in an island 2 wherein the peripheral part only is coated with silver paste 4 leaving inner part as a blank region 3b not coated with paste. Thus the bonding power between a stamp and the island 2 is reduced to restrain the island 2 from deformation though the coated region 3 covers the overall island 2. Through these procedures, any bonding of paste can be prevented from peeling off due to vibration of the semiconductor pellet in case of bonding operation.
