Title: Suction arm
Inventor: TERADA MICHIMASA
IPC: H01L21/683
Filed: 1987-06-30
Abstract: PURPOSE:To secure suction and transfer in a suction arm for sucking and transferring a transfer object if the transfer object has a warpage or attachment of foreign mattes by providing a soft and resilient member at least at the free end part of a sucking mouth to enclose the circumference of it where the transfer object is sucked. CONSTITUTION:A suction arm 11 has a soft and resilient member 16 at least at the free end part 15 to enclose a sucking mouth 13 for sucking a transfer object (semiconductor wafer) 19. By this, if the semiconductor wafer 19 has a warpage 20 or attachment of foreign matters 21 in its surface, the soft and resilient member 16 tightly attaches to the surface of the wafer 19. Leak of air through between the wafer 19 and the sucking mouth 13 is thus reduced, thereby the wafer 19 can be sucked securely.

Title: Recovering method for acid fume in pickling tank
Inventor: TATSUHARA HAJIME
IPC: C23G3/00
Filed: 1979-12-20
Abstract: PURPOSE:To reduce the consumption of hydrochloric acid and neutralizing agent remarkably, by installing filters between a duct and a collecting duct, and by returning mist, which is adsorbed by the filters, through drain holes into a pickling tank. CONSTITUTION:At the time for recovering acid fume in a pickling tank 1 of a continuous pickling line for metallic sheet, filters 5, 5 constituted of single or plural glass wool filter mediums is installed between a collecting duct 4 and ducts 2, 2' under the cover of the pickling tank 1. The acid fume 8, 8' sucked through suction holes 3, 3' passes through the filters 5, 5 and forms drain contg. acid, which drops and returns through drain holes 6, 6' to the pickling tank 1. It is preferable either to cool the filters 5, 5 or to cool acid fume 8, 8' on the upstream sides of the filters 5, 5 by the known method. Hereby hydrochloric acid is recovered efficiently without using neutralizing agent unlike conventional methods.

Title: Jig for semiconductor manufacture use
Inventor: SHIMA YUKIO
IPC: H01L21/22
Filed: 1988-06-30
Abstract: PURPOSE:To obtain a wafer free from a warp and a defect even when a large- diameter wafer is used by a method wherein a wafer-heating means is installed at a jig for semiconductor manufacture use in order to prevent a strong thermal stress from being exerted on the wafer. CONSTITUTION:A wafer 12 which has been placed on a jig 11 is heated gradually by using a heater 18 which has been buried in a part, holding the wafer 11, of the jig 11; it is heated in such a way that a temperature difference between an end edge part and the central part of the wafer 12 becomes zero. While this heating state is maintained, the jig 11 is shifted to the left and the wafer 12 is inserted into a chamber 13. Thereby, since the wafer 12 has already been heated when it is inserted into the chamber 13, a strong thermal stress is not exerted on the wafer 12. Accordingly, the wafer 12 is prevented from being warped heavily by the strong thermal stress and the thermal stress does not cause a defect of the wafer 12.

Title: Method for lining pipe inner wall
Inventor: NIINOU KIYONORI
IPC: B05D7/22
Filed: 1983-09-07
Abstract: PURPOSE:To form a film with a uniform thickness to the inner surface of a pipe by certainly detect the position of the leading part of the formed film, in applying coating to the inner surface of the pipe by injecting a fluid mixture consisting of a paint and compressed air into the pipe, by monitoring the change in the coefficient of presure fluctuation of compressed air. CONSTITUTION:In applying coating to the inner surface of the branched pipe 8 separated from a main pipe 7 at a branch point O, an accelerator 9 is attached to the opening part provided to the appropriate position of the branched pipe 8. A compressor is operated to send compressed air 14 to the accelerator 9 along with a paint 15 and both components are mixed to form a fluid mixture 17 which is, in turn, injected into the branched pipe 8. The paint particles in compressed air are adhered to the inner surface of the branched pipe 8 to form a film 19 and a paint layer 18 advances. In this case, pressure in the branched pipe 8 is detected by a pressure gauge 11 and the coefficient of fluctuation thereof is recorded by an automatic recorder 12. Because coefficient of pressure fluctuation is abruptly changed when the leading end of the film 19 reaches the branch point O with the main pipe 7, the supply of the paint 15 and compressed air 14 is stopped through a control board 13 by the signal S from the recorder 12 to prevent the paint from flowing into the main pipe 7 and the film 19 with a unifrom thickness is formed only to the inner surface of the branched pipe 8.

Abstract: PROBLEM TO BE SOLVED: To improve the chromaticity of humin by ozone treatment by a method wherein a chlorine oxidizing agent is added to raw water to effect a reaction and if a specific amount of oxidizing agent remains, ozone is added to the raw water to effect a reaction. SOLUTION: A chlorine oxidizing agent is added to raw water such as underground water containing humin or waste water colored with organic impurities similar to humin to effect a reaction. And if the residual amount of the oxidizing agent calculated in terms of free chlorine is still 0.1 mg/L or more, ozone is added to effect a reaction, whereby the chromatic components contained in underground water or the like is reduced to improve the quality of water. The residual amount of oxidizing agent to be used should be such that the residual amount of the agent is 0.1 mg/L or more, preferably 0.3 mg/L, calculated in terms of free chlorine after the oxidizing agent is caused to react with reducing substances contained in water for one minute or more, preferably five minutes or more.  Ozone is added under conditions that the residual amount of the agent is still 0.1 mg/L or more calculated in terms of free chlorine after the agent has reacted with raw water.
