Title: Horizontal type liquid phase epitaxial furnace
Inventor: OZAWA ATSUSHI
IPC: C30B29/42
Filed: 1990-05-31
Abstract: PURPOSE:To uniform the temp. distribution and the concn. distribution of a source by constituting a carbon jig capable of bringing the source into contact with a semiconductor wafer so that the contained semiconductor wafer is rotated within one plane, respectively. CONSTITUTION:The furnace is provided with a reaction tube 4, the cover 5 thereof, a heater part 6, a mechanism part 9 for rotating the reaction tube 4, and the bearing part 10 of the reaction tube 4. Since this furnace is constituted so that a carbon jig 3a is rotated at every reaction tube, the tubes connected with the inflow port 8a and the outflow port 8b of purge gas are twisted when the carbon jig is rotated only in one direction. Therefore, the tube 11 is prevented from being twisted by moving the reaction tube 4 back and forth as shown in an arrow. When the carbon jig 3a is rotated in the above-mentioned structure, a source is sufficiently agitated. The temp. distribution and the concn. distribution of the source are uniformed within the face of a wafer 1 and within a batch. An epitaxially grown layer is obtained which is uniform in thickness and free from variance in the characteristics.

Abstract: PURPOSE:To weld and join two metallic members at the same time by providing annular projections with the same diameter respectively on the fringes of the confronting faces to a metallic plate of both metallic members and forming the flat stopper surfaces adjacent to the insides of the annular projections. CONSTITUTION:A collar 3 is centered on a hole 4 of the metallic plate 1 by a positioning pin 14.

When an upper electrode 15 of a projection welding machine pressurizes a flange part 6 of the nut 2 by the first pressurizing force, the annular projections 8 and 11 come into contact with both surfaces of the metallic plate 1 in opposition. When a welding current is then applied thereto while pressurizing by the second pressurizing force, these are molten and crushed till the stopper surfaces 5 and 10 are abutted on the metallic plate and the nut 2 and the collar 3 are welded and joined efficiently coaxially on both front and rear surfaces of the metallic plate 1.

Title: Output substrate
Inventor: TANIMOTO ITARU
IPC: G01R31/28
Filed: 1981-09-09
Abstract: PURPOSE:To detect easily a fault of an output substrate, by adding a circuit to the output substrate to feed the checking data to a photocoupler and a CPU. CONSTITUTION:A photocoupler 34 is adversely inserted between the common line of output transistors (TR)41-43 and the minus terminal of an external power supply 7. When a CPU checks an output substrate, a data is first delivered to turn all TRs 41-43. Then the checking data is fed from the coupler 34. If no fault arises to the output substrate, no current flows to the common line of the TRs 41-43 to turn off the coupler 34. Then the CPU delivers a data to turn on the TRs 41-43 successively one by one, and the checking data is read in with each output of the data. When the output substrate has no fault, a current flows to the common line of the TRs 41-43 to turn on the coupler 34. Thus it shows that the output substrate has a fault when the coupler 34 is turned off.
