Title: Pressure sensitive sensor
Inventor: YAGUCHI OSAMU
IPC: B60J1/00
Filed: 1990-09-25
Abstract: PURPOSE:To improve the temperature characteristic of a sensor, to make the pressure sensitivity approximately uniform even when a bending part is present and to eliminate influences of the stain by receiving sound waves or ultrasonic waves propagating inside a tubular elastic body. CONSTITUTION:A transmitter 3 converts an oscillating signal VT supplied from an oscillator 5 to a sound wave or ultrasonic wave SO and feeds the same into a tubular elastic body 2. The sound wave SO propagates in the tubular elastic body 2 to reach a receiver 4. The receiver 4 converts the sound wave SO to an electric signal VR which passes through an amplifier 6 to be a signal VA. The signal VA is supplied to a total wave rectifying/smoothing circuit 7 and converted and output as an output voltage VOUT. The absorbing rate of the sound waves or ultrasonic waves by the air inside the tubular elastic body 2 is hardly changed to the temperature of the air. Therefore, a sensor 1 has good temperature characteristic. When the tubular elastic body 2 is pressed by the outside pressure, the propagating passage of the sound wave SO at a part of the pressed tubular elastic body 2 becomes narrow, and therefore the level of the voltage VOUT output from 7 is lowered. Accordingly, it is possible to detect whether a foreign obstacle is inserted by detecting the voltage VOUT.

Title: Fuel-supply apparatus for
Inventor: RADOUIGU BAASA
IPC: F02D19/06
Filed: 1989-09-29
Abstract: PURPOSE: To reduce exhaust gas pollution by supplying first and second fuels to a combustion chamber during a period of variable restricted time, and shutting-off the supply of the first fuel after the period of variable restricted time by a third fuel supply device. CONSTITUTION: Gasoline from a tank 60 is delivered to a carburetor 4 in normal operation, but not delivered at starting-up and idle operation. When a starter is on and an initial vacuum is produced, a needle valve 16 is opened by a solenoid 18 actuated by a vacuum switch 20. Propane in a tank 2 is supplied to the downstream side of a butterfly valve 28 to start the engine and operate it at idle speed. Then when an accel pedal is stepped on and the butterfly valve 28 is opened, a slide switch assembly 40 cooperates to actuate an electrically conductive head 84. A needle valve 34 is opened by a solenoid 36 to supply propane to a throat 26. The electrically conductive head 84 is turned off by the actuation of a pressure regulator 38 when vacuum degree rises above a predetermined value so that propane supply is stopped.  Thus it is possible to reduce exhaust gas pollution at start-up, idle operation and acceleration.

IPC: G02B7/28
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To improve AF control performance during the use of a film adapter by detecting the motion of an image caused by the move of a film by changing AF control operation through the detection of the mounting state of the film adapter, and preventing AF from being unexpectedly started again even when the motion is considerable. SOLUTION: First of all, whether it is focusing or out-of-focusing at present is judged by wobbling operation (1502). When focusing is decided (1503), a focus competition lens is stopped, and a restart monitoring processing routine (1508) is started. Next, the output of a motion detecting means is compared with a prescribed threshold value, and it is decided whether the motion of the image is considerable or not (1801). Only when the motion is judged a little as a result of decision, a restart decision routine (1509) is started but in the other case, the device is set on standby (1801). When out-of-focusing is judged (1503), on the other hand, mountain climbing operation (1504) is executed. When the result exceeds the apex of an AF evaluate signal, the focus competition lens is returned to the apex (1506 and 1507).
