Title: Drill machining method
Inventor: YAMAMOTO YOSHIO
IPC: B23H9/06
Filed: 1985-10-14
Abstract: PURPOSE:To improve positioning accuracy without deteriorating operationability by applying a photo-resist layer to the surface of a workpiece to be machined by a minute drill, then covering the surface with a mask, exposing the layer, developing it, forming a lead by means of electric discharge machining, and machining the exposed face of the workpiece. CONSTITUTION:The surface of a workpiece 12 is applied a photoresist layer 14 made of polyisoprene or the like. And it is covered tightly with a mask having a pattern of precise micro holes 16a, exposed, and then developed by using a developer made of xylene or the like. As a result, only the portions of the photo-resist layer 14 just under the micro holes melts exposing the portions of the surface of the workpiece 12. And when a voltage is applied between a discharge electrode 20 and the workpiece 12, an electric discharge occurs between the end of the electrode 20 and the exposed face of the workpiece 12 forming micro holes or wound shaped leads 12. The machining by putting a minute drill 10 on the lead can, therefore, improve positioning accuracy without deteriorating operationability.

Filed: 1989-09-04
Abstract: PURPOSE:To judge if the rear surface condition is acceptable while a handrail is left running by displaying the acceptability of the facial condition of the handrail rear surface according to whether the amount of reflex light from the handrail rear surface is greater or smaller than the reference value. CONSTITUTION:The inspection light from an amplifier part 1 is cast onto the rear surface of a traveling handrail 4 from a photoelectric sensor 2, and the light reflected by the rear surface of the rail 4 passes an optical fiber 3 and is sent to a conversion part 5 of the amplifier part 1, and is converted into electrical signals corresponding to the amount of reflex light. When the surface of the rail 4 is normal, the amount of the reflex light exceeds the set reference light amount, while the amount of reflect light becomes lower than the reference light amount if the rear surface of the rail 4 is abnormal. When this amount of reflex light is below the reference light amount, a transistor 6 operates, and a signal 'yes' is emitted from output terminals 11, 11A of the amplifier part 1 to gether with providing of the electrically leading condition. Now a DC voltage is impressed on No.1 display device 12, which is thus operated, when it can be known that the part passing by the photoelectric sensor 2 includes a failure.

Title: Susceptor for in-line continuous atmospheric pressure cvd system
Inventor: TSUKUDA KAZUAKI
IPC: C23C16/46
Filed: 1987-09-10
Abstract: PURPOSE:To lower a coefficient of thermal emission of the surface of a susceptor for decreasing thermal emission and to control its radiant heat for increasing thermal capacity, by covering the surface of the frame facing to a heat source with a heat absorbing material and the other surfaces with a heat reflecting material. CONSTITUTION:A susceptor 13 according to the invention comprises a cast stainless frame 13a whose surface facing to a heat source is covered with a chromium black body 13b. The surface of the frame carrying a semiconductor wafer 14 and the surfaces not facing to the heat source are covered with a heat reflecting material 13c such as stainless or aluminum. Heat flows 12 from a heater 12 are absorbed by the chromium black body 13b on the susceptor 13 and heats the casted frame 13a. Further, reflected heat 17 is created within the cast frame 13a by the heat reflecting material 13c. Since the heat reflecting material 13c has a low coefficient of thermal emission, little heat is emitted to the outside. The reflected heat 17 is stored in the frame 13a to increase the internal temperature of the frame and hence the heat capacity thereof.
