Title: Automatic arc welding method
Inventor: SUGITANI YUJI
IPC: B23K9/095
Filed: 1987-07-20
Abstract: PURPOSE:To perform the automatic both-side welding with a flat head shape without causing the bead burn-through by maintaining the penetration constant at a desired target value with respect to the width variation of a root gap of a butt joint to perform the automatic welding. CONSTITUTION:A changing characteristic of the size of a welding current to maintain a depth of penetration with respect to the change of the root gap width A of a groove 2 between two members 1 and 1 to be joined is found by an experiment in advance on various depths of penetration as the relation peculiar to members in use such as a welding wire 3 as a consumable welding electrode, etc. Then, at the time of welding one surface side, during welding, the width A of the groove 2 in front of the welding electrode is detected every hour and by this detected value, the real time control of the welding current in accordance with the above-mentioned changing characteristic is carried out. In addition, at the time of welding the other surface side, the welding current in which the depth of penetration maintains a second set value more than a value obtained by deducting said set value from the thickness of the root face when the width A is made to zero is selected from the above- mentioned changing characteristic. Then, the constant current control is carried out by said value and only the welding speed is controlled variably on the change of the width A and the control to maintain the height of the bead constant is carried out.

Title: Vapor phase epitaxial growing device
Inventor: MIKAMI MASAO
IPC: H01L21/205
Filed: 1985-08-16
Abstract: PURPOSE:To enable epitaxial growth in good mass production by inclining the wall of a reaction tube so that the gas passage becomes slender in the gas flowing direction. CONSTITUTION:Gas is fed from above to below a reaction tube in a section that a wafer is mounted to flow downward or upward so that the passage becomes more slender toward the downstream of the gas flowing direction by inclining on the wall of the tube 1. Thus, the consumption efficiency of raw gas is improved toward the downstream to suppress a decrease in the growing velocity due to the consumption of the raw gas from the upstream to the downstream. In this manner, an uniform epitaxial film can be grown with less irregularity in the thickness of a film between wafers.

Title: Surface lighting system
Inventor: KUSAKABE KIYOSHI
IPC: G02F1/1335
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To realize uniform light emission in a surface lighting system. SOLUTION: In this surface lighting system, light scattering parts 15 of a light guide body 7 comprises grooves, each having an equal engraving depth D, while formation intervals P of the light scattering parts 15 are set to 0.01 mm in a portion having a narrowest interval and to 0.2 mm in a portion having the widest interval. For the purpose of suppression of generation of light and dark striped pattern caused by reflection of light in the light scattering parts 15, it is preferable that the formation interval P be as narrow as possible. However, in the case that the formation interval P is too narrow, it is difficult to secure desired machining accuracy. Accordingly, as the narrowest interval taking into consideration the machining accuracy, a minimum value of the formation interval P is set to 0.01 mm.  As the maximum value of the formation interval P for which allowing visual recognition of the light and shade, 0.2 mm is selected.
