IPC: H03K5/00
Filed: 1984-12-21
Abstract: PURPOSE:To apply delay with a low distortion factor with high resolution by passing an analog signal through a path of pulse FM modulation, a delay circuit comprising a CMOS and a pulse FM demodulator. CONSTITUTION:The analog signal shown in figure (a) is inputted from an input terminal 49. The signal is subject to pulse FM modulation by an FM modulation circuit 50 and demodulated into a signal having a frequency in response to a voltage level shown in figure (b). An output signal of the circuit 50 is delayed by a delay circuit 68 as shown in figure (c). The delay signal is subject to pulse FM demodulation by an FM demodulation circuit 84 and a delayed analog signal as shown in figure (d) is outputted from an output terminal 98. The delay time T is varied by a control voltage Vc3. since each inverter is controlled by control voltages Vc1, Vc2 so that the delay time T is immune to fluctuation of temperature and power supply voltage, the signal is delayed stably and accurately.

Title: Clutch device
Inventor: KURIHARA SAKUO
IPC: F16H48/40
Filed: 1990-10-11
Abstract: PURPOSE:To obtain a large clutch torque without increasing the dimension of a clutch by applying a transmission torque onto a cam by the tightening of the first frictional clutch, and strengthening the tightening force of the first frictional clutch by the thrust force generated at that time. CONSTITUTION:The transmission torque is applied on a cam 97 by the tightening of the first frictional clutch 77, and the left and right thrust forces 107 and 109 are generated. A belleville spring 103 is deflected by the right side thrust force 109, and when the deflection quantity exceeds an interval (a), the snap ring 81 of a ring 75 presses an armature 79, and the tightening force of the first frictional clutch 77 increases. Accordingly, the clutch 77 is looked, and the slide reduces, and the thrust force of the cam 97 is increased by that portion, and also the tightening force of the second frictional clutch 63 increases. Accordingly, since each tightening force of the first and second frictional clutches 77 and 63 is strengthened by the feedback of the thrust force, a large clutch torque can be obtained without increasing the dimension of the above-described both clutches 77 and 63.

Title: Control device for spark iginition cylinder direct injection type internal combustion engine
Inventor: KITAGAWA FUKUO
IPC: F02D45/00
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To restrain misfiring by controlling fuel injection and ignition and to prevent deterioration of emission caused by discharge of unburned fuel. SOLUTION: A cylinder direct injection type injector can carry out pilot injection and main injection. In this arrangement, an energizing circuit also serving as an ignition checking circuit for a spark plug 3 is changed over from an igniter 5 into a flame ion current detecting means 7 after discharge for ignition, and accordingly, a relatively low voltage is applied to the spark plug 3 from a low voltage power source 8 so as to check whether pilot combustion occurs or not. If pilot combustion is detected, main injection is carried out. If no pilot combustion is detected, the main injection is inhibited while for example, pilot injection and ignition are repeated so as to ignite fuel.  It is noted that the control device incorporates a control mode in which main injection is carried out even though no pilot combustion is detected, and in this mode, ignition is repeated after a short time elapses from the time of main injection in order to ignite fuel.

Title: Sheet feeding device
Inventor: SUGIMOTO SHIGETO
IPC: B65H5/00
Filed: 1989-10-18
Abstract: PURPOSE:To straighten bending occurring to the tip part of a sheet and to convey a sheet, the bending of which is straightened, to a printing process by a method wherein a roller for driving an encoder to detect a sheet moving amount is arranged on the sheet inlet side of a resilient body. CONSTITUTION:A roller 102a for driving an encoder is arranged in the positions, on the inlet side of a sheet 100, of resilient bodies 5 and 6. As a result, even when bending occurs to the sheet 100 at the inlet of the roller 102a for driving an encoder, when the tip of he sheet 100 enters between the resilient bodies 5 and 6 after the occurrence of bending, the bending is straightened by applying tension on a sheet S at a portion between the resilient bodies 5 and 6 and the roller 102a. This constitution prevents residence of bending of the sheet S.
