Filed: 1993-06-15
Abstract: PURPOSE:To guarantee high filter regenerating performance while restraining the combustion temperature from becoming high at the heating combustion time of particulates in a regenerator for a filter for collecting particulates in the exhaust gas of a diesel engine. CONSTITUTION:A filter regenerator for an internal combustion engine is provided with a filter 19 for collecting particulates contained in exhaust gas; a microwave generating means 20 for heating the particulates collected by the filter 19; a combustion improving means 24 for generating combustion improving gas for accelerating the combustion of heated particulates; and a control means 37. At the time of starting combustion, the combustion improving gas is passed to the feed side of microwave from the non-feed side of microwave through the filter 19. The combustion improving gas is then passed in the reverse direction to control the combustion quantity so as to prevent the combustion temperature from becoming high and the filter from being mechanically damaged.

Filed: 1989-06-08
Abstract: PURPOSE:To reduce the power loss due to the negative work of an engine by controlling the closing timing of a suction valve in correspondence with the detection signal of the engine load and intake air temperature by an electromagnetic valve driving device. CONSTITUTION:A controller 15 allows electric current to flow in the stator coil 20 and the movable coil 24 of a valve lifter 10 as electromagnetic valve driving device in correspondence with each detection signal, and energizes an electromagnet and drives a suction valve 1. When the load detection value of an engine 13 which is detected by a load sensor 5 is less than a prescribed set load and the detection value of the intake air temperature by a temperature sensor 7 is over a prescribed set temperature, the suction valve 1 is closed during suction process.

Filed: 1989-06-08
Abstract: PURPOSE:To exactly extract a contour of each moving object by deleting a contour line related to a static object which is not contained in expanding difference image data, from contour image data generated from an input image signal. CONSTITUTION:A difference circuit 12 takes a difference of an input image signal S1 and an image signal obtained by delaying the input image signal S1 for a prescribed time by a signal delaying circuit 11, allows a moving object to appear from in the input image signal, and also, generates expanding difference image data obtained by enlarging a contour of the moving object allowed to appear by an expanding circuit 14. Subsequently, by deleting a contour line related to a static object which is not contained in the expanding difference image data, from in the contour image data generated from the input image signal S1, the contour of the moving object is separated and extracted. Accordingly, irrespective of whether a displacement value is large or small, the objects accompanied with displacement are all allowed to appear by the difference. In such a way, the contour of each moving object can be extracted exactly.

Filed: 1987-06-09
Abstract: PURPOSE:To obtain a miniaturized oscillator which is stable against temperature variation by controlling the frequency division ratio of the output of a signal oscillator with the output of a temperature sensor. CONSTITUTION:An analog signal output which is obtained by measuring the temperature of the signal oscillator 4, specially, a piezoelectric vibrator by the temperature sensor 6 is converted by an analog/digital converter (A/D converter) 8 into a digital signal, which is inputted to a control circuit 10.

Title: Deglitch circuit
Inventor: MIZUTA YOSHIYUKI
IPC: H03F1/00
Filed: 1983-08-08
Abstract: PURPOSE:To prevent the generation of an audio noise due to a glitch sufficiently by using a phase inversion circuit and composing a generated deglitch with a deglitch inverted only at its phase to output the composite signal. CONSTITUTION:A signal outputted from an electronic circuit 1 is branched and inputted to the phase inversion circuit 2, but since the circuit 2 is actuated only when a window pulse outputted from a window pulse generating circuit synchronously with a control signal 9 is inputted, the circuit 2 is in zero gain status or opened. When the window pulse is not inputted, said signal outputted from the circuit 1 is passed through a resistor 4 and outputted from an output terminal 8 to the succeeding audio amplifier which is not shown. When the signal is inputted, the circuit 2 operates as the phase inversion circuit of the gain 1, so that the signal is inverted only at its phase without changing the size of the signal, the inverted signal is composed with said signal through a resistor 5 and the composite signal is outputted from an output terminal 8. In this case, the signal itself is also erased, so that signal muting status is kept during the period.

Title: Hydraulic buffer
Inventor: TACHIKAWA JUNYA
IPC: F16F9/50
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To prevent the excessive pressure increase in a cylinder during regulation of a car height, in a self-leveling type hydraulic buffer. SOLUTION: A piston to which a piston rod 9 is coupled is fitted in a cylinder 3 sealed with oil liquid. An air spring 14 is situated between an outer cylinder 2 containing the cylinder 3 and the piston rod 9. Oil liquid is supplied in the pressure chamber 41 of the air spring 14 from a reservoir 7 through expansion of a pump chamber 24 occasioned by stretching of the piston rod. By advancing a regulation piston 40, a car height is increased and further, oil liquid of a pressure chamber is returned to a cylinder lower chamber 3b through a relief port 30. By lowering a car height through backward movement of the regulation piston 40, the car height is regulated to a constant value.  Since, during self-leveling, a pressure in the pressure chamber 41 is not transmitted directly in the cylinder 3, a pressure in the cylinder 3 is prevented from an excessive increase, and the burden of a seal part is reduced.
