Title: Valve timing control device for internal combustion engine
Inventor: MORIYA YOSHITO
IPC: F02D13/02
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To improve control responsiveness by providing a restraining means for restraining discharge of lubricating oil from a first hydraulic chamber 26 during supply of lubricating oil to a second hydraulic chamber 27, in a device for changing actuation timing by supplying and discharging lubricating oil to the first and second hydraulic chambers. SOLUTION: When duty ratio of exciting voltage impressed on a solenoid 53 of an oil control valve 44, an exchange and restraining means, a spool 52 moves left against a spring 62, and a first delivery port 55 is moved to communicate with a supply port 54. Therefore, lubricating oil is supplied to a first hydraulic chamber 26 through oil passages 8, 28, and a ring gear 25 is pressed onto the axial direction. Because lapping widths δ2, δ3 between a sleeve 51 and valve elements 63, 64 are in the relation δ2>δ3, a second delivery port 56 is not yet opened and movement of the ring gear 25 is restrained. As the duty ratio is furthermore increased, the second delivery port 56 is set to communicate with a drain port 58, and angle of a valve timing proceeds through the movement of the ring gear 25.

Title: Signal rectifier
Inventor: ANDOU FUMIO
IPC: H04L1/00
Filed: 1978-09-29
Abstract: PURPOSE:To eliminate an influence of the abnormal waveform of a FM received wave due to a single pulse noise upon a demodulated waveform, by detecting the period of a modulated wave and then by correcting the period if it does not meet fixed conditions. CONSTITUTION:An output signal from receiver 8 is supplied to waveform shaper 9, which generates rectangular signal (f9). Then, it is passed through AND circuit 14, inhibit circuit 15, OR circuits 16 and 17, and FF circuit 18 to generate signals (e18C) and (e18D), which are inputted to timers 19 and 20 respectively. As well as timer 20, timer 19 is so constituted that when a signal is applied to terminal 19A after a signal is applied to terminal 19B for time T [a half period of (f8)], an output will appear at terminal 19C T-TDELTA time later and another output will also appear at terminal 19D T+TDELTA time later. As a result, when variation in the half period of signal (f8) is above constant time TDELTA, the half period of output signal (e18C) is corrected from the half period of signal (f8) and the output of this is inputted to demodulator 10, so that if an abnormal signal would be generated due to a single-pulse noise, an error component appearing at the demodulator can be suppressed.

Title: Double voltage detection circuit with temperature compensation
Inventor: UTAKOJI AKIRA
IPC: H03G3/02
Filed: 1992-05-13
Abstract: PURPOSE:To supply a detection circuit to a high frequency detection circuit by deciding a responsiveness of the high frequency detection circuit with only a smoothing circuit constant at the output of the detection circuit so as to have only to slightly adjust a temperature compensation voltage. CONSTITUTION:A high input impedance type adder 2 consists of noninverting operational amplifiers 21, 22 and an inverting operational amplifier 23. An output D[(RV/R)+1] properly set is obtained at the output of the operational amplifier 21 based on an output voltage D generated from the operational amplifier 21 receiving a voltage drop by a forward current flowing to a 3rd diode D3 with a high input impedance via the diode whose other terminal is connected to ground (OV) through the use of a fixed resistor R and a variable resistor RV at the output side. The output D[(RV/R)+1] and an output C resulting from the operational amplifier 22 receiving an output C of the double voltage detection circuit with a high input impedance and outputting it as it is are summed. Then the operational amplifier 23 inverts the polarity and outputs an output E=-D[(RV/R)+1]-C as a detection output voltage. Thus, even when the characteristic specification of the diodes D1, D2 and the frequency of a detected output signal are subjected to change, it is coped by slightly changing the resistor RV.
