Abstract: PURPOSE:To eliminate a means such as a shutter mechanism and perform heat treatment with simple constitution by using a heat treatment device provided with a liftable cover and a wafer mounting part so as to cover the opening at the bottom of a vertical heating furnace. CONSTITUTION:A heat treatment device is constituted of a vertical heating furnace 10, which has an opening at the bottom and a compulsory cooling mechanism, a cover 20 connected with a lifting mechanism 25 and a wafer transfer part 40. The cover 20 is lifted to insert a wafer holder 30 in the furnace 10, and a wafer is heat treated under the condition that the opening is covered. The inside of the furnace 10 is compulsorily cooled by the compulsory cooling mechanism until the temperature of the holder 30 becomes 500 deg.C or below. Then, the cover 20 is made to ascend, the holder 30 is delivered to a wafer transfer part 40 and the cover 20 is lifted rapidly with a holder mounting table 36 to cover the opening. Since the wafer and the holder are well cooled to a low temperature, the opening is covered in a short time from the start of the delivery, a means such as a shutter mechanism is eliminated and heat treatment is carried out by a simply constituted device.

Title: Gas meter provided with shut-off device
Inventor: YAMANOUCHI SHIYUUJI
IPC: G01F3/22
Filed: 1981-11-24
Abstract: PURPOSE:To shut supply gas off securely through simple constitution during a fault by incorporating a shut-off valve device in a gas meter. CONSTITUTION:When supply gas should be shut off in case of a fault or emergency, a one-shot current is fed to the coil 25 of an electromagnet 24, a perma- nent magnet 28 loses the attractive force of an iron core 29 by the reverse magnetic field of the permanent magnet 28, and a valve body 23 is separated by the electromagnet 24 by the repulsive force of a separating spring 31; and the valve body 23 abuts on a valve seat 22 to close a valve device, and the supply gas is shut off to secure safety. In this case, upstream pressure, i.e. original pressure operates on the valve body 23 in a valve closing direction, so the valve is closed  by both the original pressure operating on the valve body 23 and spring 31.  Therefore, enough force to close the valve device is obtained.

Abstract: PURPOSE:To prevent heat emission and enhance the durability by allowing a piston of an air cylinder incorporated in a grinder housing to protrude a separate grinding reference surface board outside the housing during operation, by placing it in contact with a grinding belt, and thereby providing the touchless state from the belt during out of operation. CONSTITUTION:Control buttons of air cylinders 13, 14 are turned on to protrude grinding reference surface boards 17, 18 of grinding units a, b, and a handle is turned gradually to move the unit (a) little by little further toward the unit b to pinch the object by these two, and in this state the grinding works to both sides of the object is carried out simultaneously. When the work is completed, the control buttons of air cylinders 13, 14 are turned off, and the handle is rotated oppositely to allow release of the unit (a) in the opposite direction to be followed by change of the direction of object or replacement thereof. During the period other than grinding, accordingly, the grinding reference surface boards 17, 18 are always in touchless condition even though the grinding belt 3 is running to ensure prevention of heat emission or deterioration.

IPC: G08B13/02
Filed: 1989-07-21
Abstract: PURPOSE:To sense a light shock applied to a door to chime a doorbell by attaching a piezoelectric element, which detects the shock from the external, to a door itself and electrically using the piezoelectric voltage generated by the piezoelectric element as the trigger signal of doorbell chiming. CONSTITUTION:The light shock like a knock applied to the door is sensitively detected by a piezoelectric element 10, and an output transistor TR 38 is operated by the piezoelectric voltage generated at this time, and this output is amplified by an amplifier 26 and charges a capacitor 36.

Title: Rotor winding end securing metal
Inventor: IWATA NORIYUKI
IPC: H02K3/51
Filed: 1993-06-30
Abstract: PURPOSE:To ensure sufficient reliability of rotor winding even for a large diameter high peripheral speed electric rotating machine by enlarging the contact area between the outer peripheral side insulation block and the band part at the joint of a tightening member. CONSTITUTION:The rotor winding 2 is fitted in a slot made in a rotor core 1 and substantially U-shaped tightening members 8, each having threaded end parts 8a and a band part 8b for relaxing the stress concentrated at the coupling part, are arranged to pass the end part of the rotor winding 2 and secured to a supporting ring 5 by means of nuts 6. Insulation blocks 7a, 7b, 7c are interposed between the tightening member 8, the upper winding 2a, the lower winding 2b, and the supporting ring 5 with the band part 8b touching the insulation block 7a. Since the centrifugal force acts entirely on the band part during operation, stress does not concentrate on the outer peripheral insulation block and thereby the pressure can be made uniform on the contact face thus ensuring sufficient reliability.
