Title: Polishing head
Inventor: KOYAMA TORU
IPC: B24B13/01
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a stable polishing load even if magnetic attraction force is changed due to the change of relative position by obtaining magnetic attraction force which acts in the direction of axial length of a rotary shaft based on the relation of relative position in the direction of axial length between a rotor and a stator and controlling load on the rotary shaft by a pressurizer. SOLUTION: A rotary shaft 89 is pressed down by a pressurizer 123 until a load detector 117 shows a predetermined value to press a polishing tool 87 against a workpiece. The pressing down of the rotary shaft 89 is stopped at a position where the load detector 117 indicates the predetermined value, and the rotary shaft 89 and the polishing tool 87 are rotated by a motor 105 to start polishing. In a polishing head, magnetic attraction force which acts in the direction of axial length of the rotary shaft 89 is obtained based on the relation of relative position in the axial direction between a rotor 107 of the motor 105 and the stator 109 by a controller 111, and load on the rotary shaft 89 by the pressurizer 123 is controlled to a predetermined value.  Consequently, it is possible to obtain stable polishing load even if magnetic attraction force is changed due to the relative travel of the rotor 107 and the stator 109.

Title: Pre-treatment at the time of melting scrap
Inventor: TAJIMA RITSUO
IPC: C21C5/52
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To reduce the remained dioxide in exhaust gas as much as possible by absorbing chlorine base gas causing the generation of the deoxine in a scrap preheating furnace. SOLUTION: Just before or just after charging the scrap 4 into the scrap preheating furnace 3, slaked lime 7 is charged into the scrap preheating furnace, and calcium chloride CaCl2 is produced by the reaction of the chlorine base gas and dioxine generated from the preheated scrap with the slaked lime Ca(OH)2 to restrain the generation of the dioxide. Together with this effect, Ca(OH)2 is coated on the scrap to prevent the oxidation of the scrap, and the inputting energy in a melt refining furnace is saved. The calcium chloride is charged into the melt refining furnace 2 together with the preheated scrap and also, functions as slag-making promoter and thereby, available good quality slag without fluorine can be obtd.

IPC: F25B11/02
Filed: 1991-06-18
Abstract: PURPOSE:To protect a thrust bearing from excessive load by halting the supply of gas to an expansion turbine, opening an emergency pressure relief valve installed to a bypass line which connects a compressor with a gas circulation line of said expansion turbine and thereby shutting down the operation when emergency shutdown is called for. CONSTITUTION:A rotary shaft 11 is supported by a thrust bearing 14 and a journal bearing 15 between an expansion turbine 12 and a compressor 13. A pressure relief valve 20 is installed to a bypass line 19 which connects a discharge port of the compressor 13 with an exhaust air port of the expansion turbine 12 wherein an emergency shutdown valve 17 is installed to an air supply side of the expansion turbine 12. Emergency operation is controlled by means of the emergency pressure relief valve 20 and the emergency shutdown valve 17 based on an emergency signal transmitted from a signal wiring 21. during emergency, therefore, the emergency shutdown valve 17 is closed while the pressure relief valve is opened. As a result, the fluctuation in the thrust force of the rotary shaft 11 equalizes the cycle of the expansion turbine 12 side and the compressor 13 side, thereby canceling each other. This construction makes it possible to maintain the magnitude and direction of the residual thrust force acting on the thrust bearing 14 in emergency within the range of its load capacity.

Title: Abnormal mode display device in gas combustion equipment
Inventor: NISHIMURA ATSUSHI
IPC: F23N5/26
Filed: 1989-06-08
Abstract: PURPOSE:To display a calling again and to assure a safety characteristic by a method wherein a content of an abnormal mode displaying is stored in a readable or writable memory within a gas combustion control circuit and its displayed content is called up and redisplayed under any abnormal reproducing operation. CONSTITUTION:When an abnormal state such as a fire loss or the like occurs during feeding hot water in a gas hot water heater, a micro-computer C detects it, displays an abnormal content E1 at an abnormal mode display part 9 of an abnormal mode displaying device B. It is stored in a memory within the micro-computer C. Function part in a combustion passage such as a gas solenoid valve and a fan motor or the like is turned OFF and the combustion is stopped. However, since the hot water feeding passage is kept ON even if the combustion is stopped, water flows from a hot water feeding plug. If the content of abnormal state is not confirmed, the hot water feeding plug is stopped and a water flow switch S1 is turned OFF, a display of the abnormal mode is diminished and reset. However, since the abnormal mode is held in the memory, it is possible to call up and redisplay the content of abnormal state previously stored in the memory while the abnormal state regenerating switch is being pushed.

Title: Manufacture of thin film transistor
Inventor: OGASAWARA TAKAO
IPC: H01L21/223
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To enable impurity doping in a very small on and obtain throughput as high as possible, by a method wherein a source and a drain region are formed in an active layer by doping the active layer with impurity ions and then repeating the steps for cooling a substrate with cooling mechanism. SOLUTION: Doping is performed while controlling acceleration of impurity ions, in such a manner that the peak of impurity profile after doping exists in the range of a gate insulating film 5 or in the vicinity of an interface between the gate insulating film 5 and conducting layers 2a, 2b. When the doping is performed by using an ion doping apparatus, an ion beam current is intermittently sent fourth. Thereby it is made possible for the substrate temperature to exceed the heat resistance temperature of the photoresist, so that the photoresist can be used as a mask in the case of doping. Since the photoresist mask is excellent in working precision, impurity doping in a very small region is enabled, and therefore throughput can be improved.
