Title: Electronically controlled fuel injecting method for internal-combustion engine
Inventor: KOBAYASHI NOBUYUKI
IPC: F02D41/12
Filed: 1982-02-24
Abstract: PURPOSE:To enable to correct the fuel decreasing rate appropriately in an internal-combustion  engine of the type in which a reference fuel injection rate is corrected according to the operational conditions of the engine, by decreasing the fuel injection rate for deceleration according  to the lowering speed of the pressure in an intake pipe by use of a correction factor of a value obtained by integrating an integration value corresponding to the change of pressure in the intake pipe. CONSTITUTION:In controlling an injection valve 30 by determining a datum fuel injection rate  from a signal relating to the pressure in an intake pipe, given from a sensor 23 for detecting  the pressure in the intake pipe, and an engine speed signal given from a crank angle sensor 44  in a control circuit 54, the fuel decreasing rate is corrected at the time of deceleration according to the speed, detected by a throttle sensor 20, at which the opening of a throttle valve is  decreased, prior to reduction of pressure in the intake pipe. Subsequently, when the pressure in  the intake pipe is lowered, a value obtained by integrating an integration value prescribed according to the change of pressure in the intake pipe at the intervals of a prescribed time is  detected as a correction factor. Thus, both of the accelerating performance and the exhaust-gas purifying performance are improved by decreasing fuel at the time of deceleration by use of the correction factor, according to the speed at which pressure in the intake pipe is lowered.

IPC: H01L29/84
Filed: 1990-02-13
Abstract: PURPOSE:To compensate for a change in the resistance value of an active gage and measure the deformation of a piezoelectric element with a high accuracy by mounting a temperature compensating dummy gage to the piezoelectric element. CONSTITUTION:When a Z direction motor ZM is driven, gears G1 and G2 are rotated and a threaded rod G3 moves up and down to move a lever ZL up and down. Thus, the rough movement of a stage theta Z for focusing is performed. Thereafter, a piezoelectric element PZ is driven from its position and the moving quantity of the stage theta Z is detected by an active gage SG1 mounted to the element PZ, a fine adjustment being conducted. The element PZ is composed of a gage SG1 mounted in a direction wherein the elongation of the element PZ is detected and a dummy gage SG2 mounted in a direction wherein the elongation of the element PZ is not detected. The use of the element PZ to which the gage SG2 is mounted generates no measuring error due to a change in a temperature.

Abstract: PURPOSE:To cancel the adverse effect of an external disturbance light such as a direct sun-ray or an exposed light onto the detection accuracy by detecting the size based on a luminous quantity difference sensing signal of a photodetector arranged in main scanning and subscanning directions. CONSTITUTION:Luminous quantity detection signals A, B of photodetectors 21a, 21b are amplified by amplifiers 40a, 40b and inputted to a subtractor 41 and an adder 42. The subtractor 41 obtains a difference between the signals A and B and outputs the result to a divider 43. The adder 42 obtains the sum of the signals A, B and outputs the result to the divider 43. The divider 43 executes the division of both input signals and inputs the quotient C to a comparator 44. The output C of the divider 43 is larger when a reflected light from an original retainer is detected and smaller when the reflected light from the original D is received. Thus, the size of the original is detected by detecting the displacement of a detection sensor 20 from the reference position till a position when the output C changes rapidly.

Title: On-vehicle acoustic reproduction device
Inventor: ENAMI KAZUMI
IPC: B60R11/02
Filed: 1990-02-09
Abstract: PURPOSE:To form a wider acoustic field by supplying reproduced sound obtained by means of removing initial reflected sound from a reproduced signal and that obtained by means of adding initial reflected sound to the reproduced signal to a front speaker based on the correlation function of random noise and a signal from a acoustic/electric conversion means. CONSTITUTION:A digital signal processor 23 generates random noise by setting a mode change over switch 24 to a measurement mode. The processor 23 calculates the mutual correlation function between the original signal of random noise and the signal collected from a microphone 30. When the mode change over switch 24 is set to a reproduction mode, the signal obtained by reducing the level of reflected sound can be obtained by causing an acoustic signal from an acoustic signal source to pass through a digital filter 41. Then, the initial reflected sound whose delay time is comparatively long can be obtained if a delay processing 42 and an attenuation processing 43 are executed on the acoustic signal. The signals are added and they are supplied to instrument panel embedded type speakers 27.
