Title: Flux automatically adding method in electroslag welding
Inventor: SUZUKI YUJI
IPC: B23K25/00
Filed: 1994-02-24
Abstract: PURPOSE:To make unmonitored welding possible by detecting voltage change when slag pool depth is turned to shallower than suitable range and intermittently/automatically adding flux until the slag pool depth returns the suitable range. CONSTITUTION:When a slag pool depth is turned to shallower than suitable range and a flux is to be added, a voltage waveform for detecting is continuously turned to over the detecting threshold value, a detecting timer T1 23 continuously detects slag pool depth depleting condition, executing time limit completion. By closing these time limiting contacts 21, 24, 28, an adding timer T2 25 starts timing. While the adding timer T2. 25 starts timing and completes time limit, an adding motor 31 is started by closing a time limit contact 28, flux is added, a rotating speed of the adding motor 31 is controlled by a motor controller MCR 30.

Abstract: PROBLEM TO BE SOLVED: To reduce drawing load when a mold is drawn after molding so as to obtain a mold of a long life, by providing at least one convex part, which extends from one part of a land part and is spiraled at least at one time, on an upper periphery of the land part. SOLUTION: A spirally formed convex part 2 which extends from one part of a land part 3 at the bottom end and is wound around a shell part 5 at one or more times, is provided to the shell part 5 of a forging mold 1. Radius of the convex part 2 whose cross section is semi-circle is set to a value equal to such volume that the land part 3 is extruded from the shell part 5. At the time of molding, the convex part 2 is brought into contact with an inner face of a work blank, so as to restrain swelling on the inner face of the work blank and shrinkage of the inside diameter due to spring back after molding. Since the convex part 2 is a spiral shape, by rotatably holding a mold 1, the mold 1 is pulled up from a work blank while rotating along a helix angle of the convex part 2.  A contact area of the work blank and the land part 3 is reduced, so that the drawing load and the assembly at the land part 3 upper part can be reduced.

When the total value of the counters A and B exceeds 79, the counted value is processed by a traffic data recording subroutine. The program indicator PI is set to 0 after the processing and a return to a stand-by operation program is made through a connector Z2.

Abstract: PURPOSE: To increase the number of modes of a laser light spectrum to prevent the occurrence of noise due to returning light by forming the side faces of a current block layer holding a third clad layer in between so that one of the side faces in contact with a cap layer can protrude. CONSTITUTION: After a buffer layer 2, a first clad layer 3, an active layer 4, a second clad layer 5, and a cap layer 6 are successively formed on an n-type GaAs semiconductor substrate 1, a silicon dioxide layer is formed on the cap layer 6 and stripe-like silicon oxide masks 71 and 72 are formed.

IPC: H01L21/306
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To control the etching end point of a material interlayer surface by a method wherein a transition material layer is deposited on a substrate where a pattern is formed, the transition material layer and a base material are etched at the same time to form a pattern on the lower substrate, and a pattern transfer is finished when the transition material layer is completely removed. SOLUTION: A transition material layer 150 is deposited on the uppermost part of a material layer 140 where a pattern is formed. After the transition material layer 150 is deposited, the transition material layer 150 is patterned through photolithography and etched with etchant which is selective above the transition material layer 150 but non-selective about the material layer 140. The transfer of a pattern to the material layer 140 is realized by etching the transition material layer 150 and the material layer 140 with etchant which is selective about both the transition material 150 and the material layer 140.  The amount of the transition material layer 150 is determined so as to be proportional to the consumption rates of the layers 150 and 140, whereby the end point of the transfer of a pattern transfer to the material layer 140 can be controlled by completely removing the transition material 150.

Abstract: PURPOSE:To display at all times accurate cut dimension by outputting the detected value of a height sensor to the indicator of a digital display at constant timing for effecting a blade with respect to a work upon detecting the cutting dimension of the work. CONSTITUTION:Through the observation of pushing up condition of a work table by a height sensor in making cut-in starting point zero, the cut dimension (worked condition) relative to a work W can be observed practically; however, the read of cut dimension is extremely difficult due to the minute up and down movement of the work W caused by the deviated abrasion of blades 22, moreover, it may be in the digital display, the data may vary so fast as not being observed practically by the range of human view. A timing sensor 46 is provided such that the output (cut dimension detecting signal) of the height sensor 19 may output only when the blades 22 come into the central position with respect to the work W whereby the cut dimension is read out in the depth of an intermediate position exerted by blades 22. Accordingly, the cut dimension is displayed once every reciprocation to indicator 48 in digital display.
