Abstract: PURPOSE: To make it possible to adequately clean both surfaces of substrates to desired cleanliness without using hydrocarbon halide by drawing the substrates out of a water bath at a prescribed rate while allowing the liquid films which have no breaks and extend to the water surface of the water bath out of the substrate surfaces after precleaning. CONSTITUTION: The precleaned substrate 12 is completely immersed into the water bath 18 and is heated to a prescribed temp. The substrate 12 heated to the prescribed temp. is drawn out of the water bath 18 in an arrow 16 direction and is drawn out at a velocity of 0.1 to 10 mm/sec. At this time, the liquid films 44 which have no breaks and extend to the water surface flow out of the surface of the substrate 12.

Title: Laser beam machining device
Inventor: TAKIZAWA YUTAKA
IPC: B23K26/00
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To avoid influence on machining on account of instability of laser output by controlling a stage on the basis of the output of a detecting means that detects the intensity of a laser beam emitted from a laser beam source. SOLUTION: When instability is caused by a change, etc., in the lapse of time of laser itself, a change in the laser output reflects a change in the machined state of a work 18. The intensity of a laser beam 22 emitted from a laser beam source 14 is monitored through a sensor 26. In the case where lowering of the effective intensity is detected through a change in the intensity distribution of the laser beam 22, the move of a stage 20 is suppressed (reduced in speed or stopped), to performed again laser irradiation at that position and lowering of machining extent is compensated. Consequently, in the case where the laser intensity is changed to low, the intensity of the laser beam 22 made incident on the work 18 is functionally held constant substantially; therefore, laser beam machining is enable with a constant quality even for a work 18 having a large area.

Filed: 1990-09-21
Abstract: PURPOSE:To prevent foreign matter from being caught, prolong the life of bearing, prevent seizure during initial period and prevent noise form being produced by forming at least the rolling members of a rolling bearing for supporting a gear shaft out of ceramic. CONSTITUTION:Lubricating oil passes through the gear mechanism 8a and the bearing 2 on an upper gear shaft 5, flows on the inner circumferential surface of a case 1, passes through the lower side gear mechanism 8b and bearings 3, 4, and flows down to the lower part of the case 1. The bearings 2, 3, and 4 comprise an inner race 10, an outer race 11, a rolling member 12, and a holder 13 for holding the rolling member 12 respectively. The rolling members 12 are made of ceramic. Because the rolling contact surfaces are of different materials from each other, seizure is restricted even if the amount of lubricating oil is insufficient and roughening of the rolling contact surfaces due to adhesion is lessened. Even if foreign matter enters the bearing, the foreign matter is not caught with the rolling members 12. Therefore, an exfoliation phenomenon due to impression is restricted.
