Title: Manufacture of semiconductor substrate
Inventor: TAKEMURA KAZUMI
IPC: H01L21/322
Filed: 1986-04-09
Abstract: PURPOSE: To make it possible to maintain crystal defects sufficiently for bringing about gathering effect in the entire processes of circuit element manufacturing, by providing strain in the back surface in manufacturing an Si semiconductor substrate, performing heat treatment, and yielding many crystal defects for causing the strain in the back surface of the substrate. CONSTITUTION:Fine SiO2 grains 2 of about 0.1mum are made to hit the back surface of a coarsely polished semiconductor substrate 1. Thus mechanical flaws reaching the depth of about 5mum are imparted. In this way, back surface strain 3 is introduced in the crystals on the back surface. Heat treatment is performed at a temperature of 1,100 deg.C in a steam atmosphere. Thus strain- yielded crystal defects 4 in the back surface are formed. The upper surface is finished by mirror surface polishing. The applicable range of the heat treating temperature for forming many strain-yielded crystal defects in the back surface is 1,050-1,150 deg.C.

Title: Palte-like material storing and transferring device
Inventor: HATAJIMA MITSUHISA
IPC: H01L21/50
Filed: 1984-04-26
Abstract: PURPOSE:To make it possible to store plate-like materials having every possible size and to eliminate the necessity of stopping of a working line, by eliminating the inclination of a cassette which is set in order to prevent the materials stored for transfer from ejecting, when the materials are inserted in the cassette by means of a robot. CONSTITUTION:Glass plates 16 having an arbitrary size less than the maximum allowable size, may be stored into a storage cassette 28 having its bottom part 42 and back part 44 which are respectively inclined with the inclination of the back part 44 being set at a right angle to the inclination of the bottom part 42, and upon transfer of the cassette 28 the stored glass plates 16 may be prevented from ejecting. When the glass plates 16 are inserted into the cassette by means of a robot 34, an arm 68 is pushed upward by means of an air cylinder 64 so that the arm 68 pushes a movable bed 58 on which the cassette is set, and therefore, the inclination of the cassette 28 is cancelled out. Accordingly, the glass plates 16 may be stored into the cassette 28.

Title: Driving method for roller straightener
Inventor: ONO YUKIO
IPC: B21D1/05
Filed: 1986-04-10
Abstract: PURPOSE:To improve the straightening effect of a plate stock by performing a braking action on the levelling roller group at the upper stream side of a roller straightening machine and by generating a tension between the levelling roller group at the upper stream side and levelling roller group at the downstream side. CONSTITUTION:A pinching roll 14 is driven with having a braking action by a motor 16 by adjusting the gap between the upper and lower pinching rolls 14, 14 and the gap between the upper and lower levelling rollers 2, 2. Each levelling roller 2 is driven by respectively individual motor 12 and a plate stock 17 is passed through between the pinching rolls 14, 14 and between the levelling rollers 2, 2. A tension is acted on the plate stock 17 by delaying the set speed with the 1st and 2nd levelling rollers 2 as the group performing the braking action and by quickening the set speed of the levelling rollers on and after the 3rd. In this way the work can be simply performed and the straightening effect due to the tensile force addition is improved.

Title: Method and equipment for separating air
Inventor: TANAKA MASAYUKI
IPC: F25J3/04
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To reduce loss caused by the vaporization of liquefied air by introducing the liquefied air decompressed by adiabatic expansion through an expansion turbine in the limit of not vaporizing to the lower tower of a refining tower, in air separation using air separating equipment having a main heat exchanger and an air refrigerating cycle. SOLUTION: The air being compressed by a circulating air compressor 31 from the air pressure of 0.1-1.0 MPa at a previous stage to 3.0-6.0 MPa is chilled to -170 deg.C passing through a first circulating heat exchanger 32, a refrigerator 33, a second circulating heat exchanger 34 and a third circulating heat exchanger 35 and liquefied. Thereafter, the air is introduced into the lower tower of the refining tower decompressed by a Joule-Thomson expansion valve decompressing the liquefied air by the adiabatic expansion through an expansion turbine 39 in advance. Therefore, as the expansion of the liquefied air is accompanied by the work of driving the turbine, further drop of the temperature is enabled and the loss caused by the partial vaporization of the liquefied air can be reduced.

These circuits calculate rest recommendation timing on the basis of fatigue degree data before change of the operational condition, and the rest recommendation timing is given to an alarm mechanism 12. An alarm recommendation device 13 generates an alarm at recommendation timing. Recommendation of rest time in accordance with an operational condition can be performed, and an arithmetic element can be simplified.
