Title: Ashing apparatus
Inventor: YOSHIOKA HARUHIKO
IPC: H01L21/302
Filed: 1987-01-21
Abstract: PURPOSE:To prevent oxidation of the surface of mounting stage provided in a chamber during ashing, by processing the surface of the mounting stage so as to make its ozone resistance excellent. CONSTITUTION:Ashing gas is generated from an ozonator 19, which is provided with an oxygen source 18. The flow rate of the ashing gas is regulated with a gas-flow-rate regulator 20, and the gas is made to flow out of a flowing port 6 in a disk 7 to a heated semiconductor wafer 14. Thus ashing is performed. When a mounting stage 12 is made of aluminum, the surface undergoes alumite processing or Teflon processing, and ozone resisting property is improved. In this way oxidation of the surface of the mounting stage during the ashing is prevented. Attachment of oxide to the surface of the substrate to be treated can be prevented.

Title: Heat-treatment apparatus of compound semiconductor substrate
Inventor: WATANABE YOSHIO
IPC: H01L21/223
Filed: 1990-01-18
Abstract: PURPOSE:To quickly cool a compound semiconductor substrate after a heat treatment by a method wherein the substrate is installed in a region on a flat face which has been formed by cutting a container along the tubular axis in the lengthwise direction. CONSTITUTION:A region, in a container 11, where a compound semiconductor substrate 12 is installed is constituted on a flat face which has been formed by cutting the container 11 along the tubular axis 13 in the lengthwise direction. Consequently, since an area where the substrate 12 comes into contact with the container 11 becomes large, the cooling time of the substrate 12 is shortened, a change in a carrier concentration at a cooling operation is reduced, and an irregularity in the carrier concentration inside a crystal plane and an irregularity in carriers between heattreatment lots are reduced. Thereby, the compound semiconductor substrate whose carrier concentration is not changed inside a substrate face and with reference to the heat-treatment lots can be obtained, and the substrate after a heat treatment can be cooled quickly.

Abstract: PURPOSE:To improve the productivity of the centering work and eliminate the influence upon a lens to improve the capacity of the lens, by centering the lens with a holding frame and two centering jigs which are aligned precisely and holding the lens with a holding ring and an elastic adhesive. CONSTITUTION:A lens holding frame 12 and a centering jig 17 are so attached that they are aligned precisely, and a rear lens L4 is inserted into an inside diameter part 12c of the holding frame 12 and is brought into contact with the front end face of a projecting stripe 16, and another centering jig 18 which has the same axis as the centering jig 17 precisely is moved right to press the lens L4, thus centering the lens automatically. Next, a holding ring 14 is inserted, and an adhesive 19 is packed on the outside circumferential face of the lens L4, and then, the adhesive has no influence upon deformation of the lens after hardening because of its elasticity. A front lens L3 is set in the same procedures. Consequently, the productivity of precise centering is improved with centering jigs, and precise processings are unnecessary for holding rings 14 and 13, and the elastic adhesive has no influence upon lenses, and thus, the capacity of the lenses are improved.

Title: Construction method for road with buried heater
Inventor: KOTANI TETSUO
IPC: E01C11/26
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent the deviation of a heater layer by laying more than one layer of flexible sheets having a length larger than the laying interval of a heater layer on the heater layer constituted with protective sheet/heater/ protective sheet arranged intermittently. SOLUTION: A heater layer 1 is intermittently layer in such a manner that its length direction almost coincides with the direction of road width. This heater layer 1 is laid in two rows for each traffic lane. A lead wire 3 of a heating body is connected to a conductive wire 5 at the side of road shoulder, and the conductive wire 5 is connected to current supply facilities provided at an external portion of the road. A flexible sheet 7 is laid in the progressing direction of the road and an asphalt layer is placed on the flexible sheet 7. By this configuration, the area of adherence between the flexible sheet and a backing surface increases more than that of rubber asphalt sheet of the heater layer, so that a stress applied to the heater decreases even though the adhesive strength per unit area is not different from the conventional one.  Thus, deviation or breakage of a heater layer can be prevented.
