Title: Solid-state image pickup device
Inventor: SEKIGUCHI KATSUO
IPC: H04N5/341
Filed: 1991-12-26
Abstract: PURPOSE:To excellent hold a characteristic by reducing the heating value of a solid-state image pickup device. CONSTITUTION:A CLK1A is sent from a TG3 and it is amplified in a driver 2 based on voltage V2. By the CLK1A, unnecessary electric charge remaining in a solid-state image pickup device 1 is swept out. Then, a reading gate pulse GP is impressed on the solid-state image pickup device 1 and the signal electric charge stored in a receiving light part is read. Then, a CLK1B is amplified based on voltage V1 in the driver 2 and it is impressed on the solid-state image pickup device 1. Thus, the signal electric charge read from the receiving light part is transferred to a storage part. At this place, the voltage V2 is set to be about 80% lower than the voltage V1, for instance. Therefore, the amplitude of the CLK1A to be used when unnecessary electric charge is swept becomes smaller compared with conventional one and thus, power consumption is drastically reduced. Therefore, the heating value also becomes drastically smaller and the characteristic of the solid-state image pickup device 1 can be held in a good condition.

Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To ensure a predetermined vacuum suction force in a sheet feeder having a vacuum-suction pad for vacuum-sucking a sheet, even with the use of a sheet of larger air permeability in the sheet feeder and even when such sheets stacked up run short. SOLUTION: When a turn arm 3 turns downward to lower a vacuum-suction pad 2, the pad 2 vacuum-sucks the uppermost sheet S in the cassette. When the turn arm 3 turns upward thereafter, the pad 2 having vacuum-sucked the sheet S is correspondingly lifted to its original position. In that state, the uppermost single sheet is separated from the other by a separation claw 20. The sheet S vacuum-sucked by the pad 2 is then taken out of the cassette by the rightward movement of a movable mount 5. The cassette has a suction assist sheet 100A of smaller air permeability under the lowermost sheet, which serves to ensure the reliable vacuum suction of even a sheet S of larger air permeability through the vacuum suction force of the pad 2.

Title: Slip control device for vehicle
Inventor: HARA MITSUO
IPC: F16H63/50
Filed: 1991-12-27
Abstract: PURPOSE:To control excessive slip at the time of starting acceleration by composing a vehicle slip control device of line pressure control means or the like which controls the line pressure of an automatic transmission on the basis of both state quantity detected through internal combustion engine output detecting means and the coefficient of friction determined through slip state detecting means. CONSTITUTION:When the occurrence of slip is judged, line pressure is determined as the function of the absolute value of target driving torque computed by an internal combustion engine electronic control unit. Control is carried out so that a driving wheel speed and target speed mutually coincide, and the coefficient of friction (mu) on a road surface is determined in a space from the starting time t0 of a vehicle to a time t1 when the driving wheel speed V becomes higher than the target speed V1. After that, target line pressure is determined using the coefficient of friction (mu). When the driving wheel speed V becomes below decision speed Vh at the time t2, the slip is considered to be dissolved, and the control at the time of ordinary running is therefore executed.
