Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To enable the use of a rust preventive coating material on the market and to effectively utilize cut chips and defective chips generated in ALC production by mixing a rust preventive coating material with a specified amt. of ALC powder. SOLUTION: A rust preventive coating material of 0.5 to 5 is mixed with ALC powder by the weight ratio of 1. In the case the amt. of the rust preventive coating material is less than 0.5, its rust preventing function deteriorates, and, in the case it exceeds 5, after the application of the coating material, sagging occurs, and the color matching with an ALC panel deteriorates. Moreover, preferably, the particle size of ALC is controlled to <=1 mm, and the average particle size is controlled to 0.1 to 0.2 mm. In the case the particle size of ALC exceeds 1 mm, its mixability as the rust preventive coating material deteriorates and is apparently unpreferable, and in such a case, the smaller the better. Furthermore, in the case the average particle size is less than 0.1 mm, the sagging of the rust preventive coating material is easy to be generated, and in the case it exceeds 0.2 mm, the mixability of the coating material deteriorates and is apparently unpreferable.

Title: Queuing system of memory block
Inventor: YAMAMOTO HIROHIKO
IPC: H04Q3/545
Filed: 1983-03-22
Abstract: PURPOSE:To realize the queuing control more easily by setting the last block to a self-link state in the linkage constitution of processing request memory blocks in a queue. CONSTITUTION:When being started, the queuing control reads in a value stored in a head pointer. Said queued processing request is taken out from the queue, and thereafter, this processing request is started. If there are no normal queued processing requests, the read value of the head pointer indicates a processing request of TR2 because the special processing request indicated by TR2 is stored in the head pointer. This processing request is taken out from the queue; however, since this processing request in the queue is set to the self-link state, the form of the queue is not changed and is held in a state (a) even after the processing request is taken out from the queue. Thereafter, this processing request is started.

Title: Beam projection device
Inventor: ONO MASAHIRO
IPC: G01C5/00
Filed: 1995-03-07
Abstract: PURPOSE: To obtain a beam projection device with stability and high accuracy capable of preventing variation of a beam diameter to the best of its ability by controlling a position of a beam waist of projection light flux that varies along the temperature variation. CONSTITUTION: When a rotation motor 66 is rotated at a constant speed, the rotation of the motor 66 is transmitted to a rotation beam projection section 15 so that the projection section 15 is rotated relative to a hollow member 21. As a result, laser light flux L1 emitted from a rear group lens 32 can be deflected by 90deg. by a pentaprism 35 and laser flux L3 can be continuously emitted in the horizontal direction while the projection section 15 is rotated. In this case, even when a beam waist position of the flux L3 tends to shift along the temperature variation from a prescribed position, a microcomputer 82 moves the front group lens 31 relative to the lens 32 by a movement quantity corresponding to a detected temperature in accordance with a temperature detection signal from a temperature detecting means 90.  Thereby, it is possible to hold the beam waist position at a prescribed position.

Filed: 1991-03-13
Abstract: PURPOSE: To easily and reliably check existence of sealant in an overpressure valve by introducing liquid sealant into the overpressure valve at a higher temperature than an ambient temperature and by continuously monitoring a temperature of the valve by an infrared sensor. CONSTITUTION: A delivering device 30 of sealant makes a small amount of sealant flow out to a nozzle 21 as sealant drips 6 and introduces into a prepared overpressure valve 1.
