Title: Vapor reaction method for semiconductor wafer
Inventor: YANAGIDA NORIYOSHI
IPC: C30B25/12
Filed: 1978-06-02
Abstract: PURPOSE: To reduce occurrence of the crystal defect at the growth layer by coating previously with the Si 3 N 4  film over the exposed surface of the Si wafer mounting susceptor which is used for the vapor reaction.  
     CONSTITUTION: Susceptor 3 onto which Si wafer 5 is installed obliquely to the gas flow within airtight container 1 for vapor reaction which is surrounded by the heating coil and contains gas introduction tube 2 and gas exhaustion tube 6 at the edge part. In this case, as shown in the separate figure, the entire surface of core material 13a of susceptor composed of carbon or graphite is coated with film 13b of Si 3 N 4  not the ordinary SiC. As a result, the linear thermal expansion coefficient of film 13b becomes 3.6×10 -6 /°C which is approximate to that of the carbon, thus reducing greatly the heat stress. Furthermore, the impurity gas contained in the carbon never intrudes into the epitaxial layer with no crystal defect caused, thus  increasing the life time of the epitaxial layer.

Title: Method for sandwiching sheet member
Inventor: YOSHIE TORU
IPC: B65H37/04
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to increase the number of sandwiching members to be contained even if the members are wide by drawing one of the members of substantially flat plate shape contained in a containing chamber, bending the member and sandwiching the end of a sheet member therebetween. SOLUTION: The contact surface 41A of the protruding stripe 41 of a slider 41 is brought into contact with the side of a sandwiching plate 105A by the movement of the slider 34, and the plate 105A is drawn from the gap of a cartridge body. Clamps 73 and 74 are narrowed therebetween by the rotations of clamps 51, 52, and a sandwiching plate 105 is bent. At this time, the slider 34 is bent in an L shape while the plate 105A is pressed by the slider 34. Thus, since the plate 105A is bent while the bent part of the plate 105A is pressed in contact with the end of a sheet member S, it can prevent the member S from being sandwiched only between both the ends of the plate 105A.

Title: Demagnetization circuit for permanent magnet
Inventor: MIYAZAWA SEIJI
IPC: H01F13/00
Filed: 1984-04-04
Abstract: PURPOSE:To quickly demagnetize permanent magnets having different magnet performances by repeatedly and alternaltely supplying a DC current in the forward and backward directions to a coil from the power source and gradually lowering the level of such DC current. CONSTITUTION:An AC input 7 is converted to a DC current by a DC power supply 8 which can freely change an output voltage. A relay BOX10 comprises a switch and a timer for controlling a DC current to ON and OFF and for normal and reverse connections. A field generating coil is connected to an output terminal 11 and it is used as the demagnetization circuit of permanent magnet. The demagnetization circuit of this permanent magnet is connected to the demagnetization apparatus in order to generate demagnetization waveform. For demagnetization, a field is generated in the positive side by flowing a DC current to the demagnetization coil and then a field is generated in the negative side by changing the direction of current with the timer. Such operations are repeated for several times and intensity of magnetic field is gradually reduced by controlling a DC current. Thereby, demagnetization can be realized perfectly irrespective of a kind of demagnetization coil and even when a coersive force of magnet to be demagnetized is unclear.
