Title: Setting of phase difference in two sets of pulse trains of rotary encoder
Inventor: KONDOU SHIROU
IPC: G01D5/36
Filed: 1981-02-17
Abstract: PURPOSE: To simplify the positioning of component elements while obtaining two sets of pulse trains in a desired phase difference by setting a phase difference for light quantity detection pulse trains of a light receiving element with axial displacement of a rotary plate and a fixed slit plate relatively.  
     CONSTITUTION: As a rotary plate 1 is moved in the direction B while the light source 20 is shifted in the direction A along the optical axis PC, the quantity of light received by a light receiving element 31 advances in the phase while that by a light receiving element 32 lags. When the rotary plate 1 is shifted toward slits 11 and 12 of a stationary plate 10, the phase of the quantity of light received by the light receiving element 31 lags while that by the light receiving element 32 advances. When the stationary slit plate 10 is shifted in the direction A while the rotary plate 1 is fixed with respect to the direction of the optical axis PC, a phase deviation occurs opposite to that caused when the rotary plate 1 is shifted. Such a shift in the phase according to the displacement of the slit plate in the direction of the optical axis is used to set a phase difference for the quantity of light received by the light receiving elements 31 and 32.

Title: Method and device for cleaning of heat exchanger
Inventor: ISHII YOSHIAKI
IPC: F28G9/00
Filed: 1983-02-15
Abstract: PURPOSE:To make it possible to clean the heat transfer surface of the heat exchanger effectively by using a simple device by a method wherein when the heat exchanger for cooling a cleaning liquid used for purifying a high temperature gas is cleaned, a washing liquid having a higher pH than in the ordinary operation of the heat exchanger is brought into contact with the heat transfer surface on the cooled side of the heat exchanger for a predetermined period of time. CONSTITUTION:Scales generated on the heat transfer surface of the cooled side of a cooler 9 due to the existence of solid components in the washing liquid is measured with a differential pressure meter 13 and a flow rate meter 14 and when the differential pressure or the flow rate of the washing liquid becomes higher or lower than a predetermined value, the heat transfer surface is cleaned. That is, the supply of a pyrolytic material is stopped for a time or the amount of supply of the material is reduced and an inert gas and an alkalline solution are injected into the washing liquid to increase the alkalinity of the washing liquid by opening valves 15 and 16 attached to a gas supply pipe 5 and an alkalline solution supply pipe 6. As a result, the scale becomes softened to be exfoliated easily by alkali. Further, the heat transfer surface is disturbed by air bubbles generating due to the injection of the inert gas so that the scales are exfoliated to thereby further increase the cleaning effect.

IPC: B60G17/08
Filed: 1982-02-16
Abstract: PURPOSE:To automatically control damping force of a shock absorber, by detecting a starting condition or a change of speed or the like. CONSTITUTION:Under a condition with a car speed V below a reference car speed VL, if all starting conditions are satisfied, a microcomputer 11 respeatedly executes a closed loop of a step 102 or 109, accordingly immediately after starting, damping force of shock absorbers from 12 to 15 is set higher to prevent front lifting and rear sinking at a rapid start. Then under this condition the speed V becomes at least the speed VL, even when the starting condition is released, the damping force is still set higher during a prescribed period t1. Then if t=t1, the microcomputer 11 is inverted to a decision result YES in a step 112, and the absorbers from 12 to 15 are decreased lower to ensure good comfortableness of riding in a normal running condition.
