Patent JP-S59155774-A (JP)
Title: Linear encoder
Inventor: NAKAMURA ARATA
IPC: G01S11/14
Filed: 1983-02-25
Abstract: PURPOSE:To elevate the detection accuracy with a simplified construction by detecting the movement of an object to be moved having the length of an ultrasonic wave as distance unit to eliminate the need for previously forming a graduation on a table on which the object being moved is arranged. CONSTITUTION:When an ultrasonic wave is emitted to a receiver 5 of a head 3 from a transmitter 2, an ultrasonic signal received is amplified with an amplification circuit 6 to be compared with an ultrasonic signal of an ultrasonic wave oscillator 1 by a phase comparator 7. When the distance l between the transmitter 2 and the receiver 5 is of integral fold magnification as large as the wave length of the ultrasonic signal, the ultrasonic signals become the same in the phase to maximize the output from the phase comparator 7. As the head 3 moves to the transmitter 2 continuously, the signal from the phase comparator 7 turns to an analog signal having the maximum value at an interval of 360 deg. in the phase difference. The number of pulses of a pulse signal from a waveform shaping device 8 is counted and the distance equivalent to the multiplication value of the wavelength by counts is detected as movement of the head.

Inventor: HARA SHINJI
IPC: F02D43/00
Filed: 1990-02-09
Abstract: PURPOSE:To prevent the sharp start of a vehicle by detecting the revolution speed of an engine, simultaneously with the execution of flying boost-up and restricting the intake quantity when the revolution speed is higher than a prescribed idling revolution speed, while by increasing the opening degree of an intake conduit in case of low speed. CONSTITUTION:When the exhaust gas energy supplied from an engine 1 is large, a rotary electric machine 3 is operated as dynamo, and the exhaust energy is converted to the electric energy and recovered. When the engine is at a sharp acceleration or at a low speed high load operation, the rotary electric machine 3 is operated as electric motor, and the compressor 22 of a turbocharger 2 is driven to supercharge the intake air into the engine. In this case, it is judged if the start preparation of the vehicle is completed or not, and if the judgement is 'YES', a timer is reset, and flying boost-up is started. When the number of revolution of the engine 1 is a prescribed idling revolution high speed, the opening degree of a throttle valve 13 is restricted, while in case of low speed, the opening degree of the throttle valve 13 is increased.
