Title: Apparatus for producing liquid crystal substrate
Inventor: UEDA YOICHI
IPC: H01L21/3065
Filed: 1989-03-31
Abstract: PURPOSE:To simplify the maintenance operation in a hermetic treating vessel which is made into divided structures by providing detaining members and detaining parts respectively to the divided parts of the hermetic treating vessel and forming these members and parts in such a manner as to allow clamping/unclamping by a single operation. CONSTITUTION:An upper chamber 31 and lower chamber 32 which are made into the divided structures to allow opening and closing by hinge mechanisms are closed and thereafter, rings 44 of clamping mechanisms 35 are detained to hook members 34 of the chamber 32. Levers 41 are sufficiently shifted downward beforehand in such a manner that the position at the bottom end of the rings 44 exceeds the hook member 34. The levers 41 are thereafter shifted toward the chamber 31 side, by which the rings 44 are moved upward and the hook members 34 are pressed and fixed to the upper side. The upper and lower chambers 31, 32 are thereby clamped. Hermetic members are provided on the contact surfaces of the chambers 31, 32 and a hermetic state is maintained in the treating chamber by clamping of the clamping mechanisms 35. The treating chamber is opened by carrying out the operation in reverse of the clamping operation. The easy opening and closing of the treating chamber are thus executed.

Title: Remover of slag froating on surface of molten metal in ladle
Inventor: MIYAMAE KIYOSHI
IPC: B22D37/00
Filed: 1978-07-07
Abstract: PURPOSE:The captioned remover which is so arranged as to be able to effectively remove slag by dipping a slag capturing pipe having a wide opening attached to a pressure-reduceable slag containing tank to the ladle and suction-removing the slag. CONSTITUTION:The slag remover is hoitsted down by a crane or the like into a ladle 101 placed in the specified position and is dipped in molten metal 102 to the extent that the circular cone shape part of the slag capturing pipe A sinks just within the molten metal 102. Here, exhaust is started through exhaust port 4 when the slag capturing pipe A comes right above the slag floating on the molten metal. This is continued until the level of the molten metal reaches near the top end of the suction pipe 108. During this time, the slag in the ladle is pushed up to the molten metal and is sucked into the slag containing tank B. The suction pipe 108 protrudes by penetrating upward the bottom of the slag containing tank B, by which back flow of the slag again into the ladle 101 is prevented.

Title: Head positioning mechanism for magnetic disk device
Inventor: HAYASHI NOBUHIRO
IPC: H03M13/23
Filed: 1993-03-17
Abstract: PURPOSE:To improve the positioning accuracy of a head by always controlling an off-track amount to an optimum amount by efficiently calculating an optimum shift amount. CONSTITUTION:A corrected value generating circuit 12 performs correction control so that a reproducing head at a target track position can be off-tracked from a track center oppositely just for the shift amount in the disk radius direction of a recording head to this reproducing head, and an error measuring circuit 17 measures the bit error rate of a regenerating signal in a data zone while changing the off-track amount.

Title: Wafer carrier
Inventor: SATOU ATSUTOSHI
IPC: B65D85/86
Filed: 1986-04-09
Abstract: PURPOSE:To make it possible to prevent corrosion of the wiring pattern of a semiconductor wafer, by constituting the main body of a carrier with a material, whose ionization tendency is higher than that of the material of the wiring pattern. CONSTITUTION:As the material of the electrode pattern of a wafer, a corrosion proof member 3 comprising a material, whose ionization tendency is higher than that of aluminum that is used in general, is fixed with screws 4. When a wafer is inserted in a vertical groove 1b, the electrode pattern of the wafer is contacted with a carrier main body 1 and conducted to the corrosion proof member 3 through the groove 1b. Under this state of the wafer insertion, since the ionization tendency of the corrosion proof member 3 is higher than that of aluminum, which is constituent metal of the electrode pattern material and the carrier main body 1, the electrode pattern material and the carrier main body 1 are negatively charged by a battery effect. Therefore, corrosion does not occur in the electrode material even though corrosion occurs in the corrosion proof member 3. Thus, wire breakdown in the wiring pattern can be prevented.
