Title: Ultrasonic measuring apparatus
Inventor: FUJII TORU
IPC: G01F1/66
Filed: 1985-07-17
Abstract: PURPOSE:To enable the stable measurement of an ultrasonic wave propagation time, by determining the gain and threshold value of an amplifier to the first or second wave in the reception of an ultrasonic wave. CONSTITUTION:The first wave in the reception of an ultrasonic wave propagating through a pipeline 1 through an amplifier 8 is compared with a threshold value by a comparator 9 corresponding to the control of a program by CPU27 of a control circuit 32 and, when said first wave is the threshold value or more, the output of a latch circuit 11 is reversed to L to stop a counter 14 and an ultrasonic wave propagating time is measured. At this time, the peak value of the output of the amplifier 8 is compared with a reference value and the gain of the amplifier 8 is controlled by the circuit 32 and a D/A converter 15 corresponding to the output of a latch circuit 18 responding only to the first wave in the reception of the ultrasonic wave through the AND gate 30 closed by the L-output of the circuit 11 and the peak value comes to the optimum value almost equal to the reference value. When the first wave in the reception of the ultrasonic wave is low, the circuits 32 refers to a threshold value table 22 and the threshold value of the comparator 9 is altered through a D/A converter 10 to be allowed to correspond to the second wave in the reception of the ultrasonic wave and similar processing is performed. Therefore, the stable measurement of a propagation time is performed without being affected by noise and a reflected pulse.

Title: Vehicle height adjusting device
Inventor: MIMUKAI KEN
IPC: B60G17/04
Filed: 1983-08-29
Abstract: PURPOSE:To simplify the structure to reduce assembly processes of a telescopic vehicle height adjusting device by providing a levelling mechanism that positions a piston rod at a predetermined height in the cylinder. CONSTITUTION:When a piston rod 2 moves downward, a free piston 41 contacts a stopper 43 to cause a gap between its lower end and the upper end of the engagement section 45 of the piston rod 2. The pressurized oil O flows into a lower chamber B through the inside of the piston rod 2 to cause the gas pressure in an accumulator 11 to rise to gradually lift the piston rod 2. When the engagement section 45 contacts the lower end of the free piston 41 at a predetermined height, the supply of the oil pressure is terminated. On the other hand, when the piston rod 2 moves upward, the free piston 41 is lifted up to allow an oil path in a small diameter section 14a of a control rod 14 to be formed, and the pressure oil is returned to a hydraulic circuit O to lower the vehicle height. In this manner, the structure can be simplified and assembly processes can be reduced.

Abstract: PURPOSE:To adjust lighting without rush current flowing to a light adjusting apparatus and causing flicker by giving a controlling signal to a controlling part installed in a lighting apparatus from the light adjusting apparatus. CONSTITUTION:An apparatus 1 for lighting an incandescent lamp by an output of a high frequency obtained from a commercial electric power source AC and a light adjusting apparatus 2 to generate a light adjusting signal in which a part of voltage waveform of a semicycle is set to be an ON period and the remaining to be an OFF period synchronously with the commercial electric power source AC are installed and the lighting apparatus has a controlling part which carries out starting and stopping of high frequency oscillation corresponding to the ON period and the OFF period of the light adjusting signal. When a photo-receiving device PD is turned on, the oscillation of the lighting apparatus l is stopped and the photo-receiving device PD is turned off, the oscillation of the lighting apparatus l becomes possible. Since the light adjusting apparatus only gives a light adjusting signal to instruct the starting and stopping of the oscillation to the controlling part, flicker of an incandescent lamp is not caused unlike in the case of using a phase controlling device.
