Title: System for controlling constant heat input in hot wire tig welding
Inventor: YADA YOSHIO
IPC: B23K9/12
Filed: 1984-12-19
Abstract: PURPOSE:To promote the high efficiency in welding with making the heat input constant by detecting the variation in the distance between the base metal under welding and resistance electrode as the variation in voltage and by varying the inclination of the electricity-voltage properties of the heating power source according to the voltage variation thereof. CONSTITUTION:A heating power source 7 has the external characteristics that the base metal 8 of the filler material 4 being found experimentarily and resistance welding electrode resistance value and the resistance value of the cable for welding are taken into consideration and detects the variation between the base metal 8 and welding electrode 3 by a voltage detector 5 as the variation in voltage during the welding. This is inputted into a resistance value arithmetic circuit 9 and inversion circuit 10 to find the necessary power source external characteristic inclination and this result is inputted into the external characteristics control circuit 11 for controlling. The series arc caused by the unevenness in the melting speed of the filler material in the conventional hot wire TIG welding and the sticking phenomenon of the filler material can be thus eliminated and also the stabilized melting speed of the filler material is obtd. and the high efficiency in welding can be promoted.

Title: Photoelectric converter device
Inventor: UCHIDA YUTAKA
IPC: H01L21/66
Filed: 1990-10-05
Abstract: PURPOSE:To eliminate the need of a focal point adjustment at a photoelectric conversion surface, i.e., an adjustment of a spot size by converting laser light from a semiconductor laser in an electron beam in a photoelectric converter part and outputting the latter. CONSTITUTION:When predetermined voltage is applied from a semiconductor laser power supply 12 to a semiconductor laser 11, laser light is emitted from the semiconductor laser owing to internal excitation. The laser light is at once converted to electrons in a photoelectric conversion part 13 and is outputted. The electrons generated from the photoelectric conversion part 13 are drawn out by an accelerating electrode 17 into an electron beam, which beam is outputted after passage through a predetermined orbit by acceleration. An equivalent spot size of the electron beam at that time depends upon the size of an active layer of the semiconductor laser 11, generally about 1mum. Thus, an electron beam of a satisfactory predetermined spot size can be yielded without use of a spot diameter adjusting mechanism.

Title: Bonding method for semiconductor wafer
Inventor: SHINPO MASARU
IPC: H01L21/68
Filed: 1984-12-18
Abstract: PURPOSE:To prevent any polishing flaw or crack from generating in the lapping process by a method wherein a step is provided along the outer peripheral part of the polished surface of the semiconductor wafer on at least one side of two sheets of semiconductor wafers and two sheets of the semiconductor wafers are directly bonded. CONSTITUTION:A step 2 is processed along the outer periphery of the mirror polished surface of a wafer 1 on one side. The width of the step is made a little larger than the polished sag and the height thereof is made equal to the residual thickness in after the lapping process finish. The processing depends upon an etching. After the step is processed, the wafer 1 is sufficiently cleansed and the fellow polished surfaces of the wafer 1 and the other wafer 3 are made to directly bond without making any foreign substance interpose between the polished surfaces of both wafers. A resin 4 so forth are filled in the gap of the step 2 of the bonded body obtainable and a lapping is performed. As the gap to be formed by the step 2 is previously made equal to the desired residual thickness in after the lapping process finish, the processing finishes at the point when the filling material 4 is exposed and the filling material 4 is removed. According to this constitution, the generation of a polishing flaw, which is caused by some lacking of the non-bonding parts at the time of lapping, or the generation of a crack due to the flaw can be prevented.
