Patent JP-S62185826-A (JP)
Title: Production of high-strength gear
Inventor: MAEDA CHIKATOSHI
IPC: C21D9/32
Filed: 1986-02-08
Abstract: PURPOSE:To produce a gear having improved strength and toughness by forming residual austenite on the surface layer by carburization hardening in which carbon potential is specified then transforming only the extreme surface part of the residual austenite to martensite by strong working. CONSTITUTION:The carbon potential is controlled to a 1.0-1.2% range to form a large amt. of the residual austenite in the surface layer (about 0.4-0.5mm depth) of the gear when the gear is held at the hardening temp. in the carburization hardening treatment in the stage of subjecting the gear to carburization hardening. The gear is then subjected to physically strong working such as heavy-duty shot peening or heavy cutting (strong cutting) to transform only the residual austenite in the extreme surface layer part (about 0.1-0.2mm depth) to the strain-induced transformation type martensite. A large amt. of the austenite layer is thereby made to remain in the lower part (about 0.3-0.5mm depth) of the martensite layer so that said layer functions effectively to prohibit the progression of fatigue crack.

Title: Mask holding apparatus
Inventor: FUJIOKA HIDEHIKO
IPC: H01L21/30
Filed: 1987-02-09
Abstract: PURPOSE:To obtain a mask membrane having a flatness as desired, by changing attracting forces applied by solenoid coils to various parts of a mask frame to which the mask membrane is attached, so as to remove component materials deteriorating the flatness of the mask membrane. CONSTITUTION:A mask frame 2 is moved close to a mask holder 3, so that the mask holder is attracted by permanent magnets 4a, 4b, 4c and 4d. After being attracted, the flatness of a mask membrane 1 has a fixed value. If data of deflection configurations of the mask membrane 1 are previously obtained from a flatness measuring interferometer system, it can be known which parts of the mask membrane are projected and which parts are recessed when the holder 3 is attracted by the magnets. Thus, the flatness of the mask membrane can be corrected, based on these data, by supplying respective solenoid coils 5a, 5b, 5c and 5d with currents controlled indenpendently through respective leads 6a, 6b, 6c and 6d. By this correction, any component material deteriorating the flatness of the mask membrane are removed and the flatness as desired can be obtained.
