Title: Method for decreasing residual stress of fitted welding zone of inside surface of pipe
Inventor: UMEMOTO TADAHIRO
IPC: C21D9/50
Filed: 1990-09-25
Abstract: PURPOSE:To prevent the generation of a defective part near the welding zone on the inside surface of a base pipe by subjecting the base pipe walls parted from the weld zone to both sides thereof to induction heating to impart a temp. difference between the base pipe walls and a rigid member, thereby generating a tensile stress on the inside surface of the base pipe near the weld zone. CONSTITUTION:A gaseous atmosphere is maintained around the base pipe 9 and an induction heating coil 21 is wound around this pipe. The rigid member 16 is mounted by the weld zone W to the inside surface of the base pipe 9. The winding range of the above-mentioned induction heating coil 21 is set so as to satisfy the following equation in accordance with the spacing distance L from the center of the weld zone W to the edge of a heating part, the average radius (a) of the base pipe 9 and the thickness (h) of the base pipe wall: L=0.6(ah)<0.6>. The heating width H is set so as to satisfy the conditions of the following equation: H>=4Xh. The base pipe walls parted from the weld zone W to both side thereof are then induction-heated. The large temp. difference is imparted between the base pipe walls and the rigid member 16 in this way and such a large tensile stress as to exceed the yield point is generated as shown by arrows in the inside surface of the base pipe near the weld zone W by the thermal expansion of the high temp. part and the expansion suppressing effect of the rigid member 16, and this part is plastically deformed. The above- mentioned temp. difference is decreased and the residual stress of the inside surface of the base pipe is shifted in a compression direction when the induction heating is stopped. Then the generation of the defective part, such as stress corrosion cracking, in this part is prevented.

Title: Induction motor
Inventor: TAKAHASHI KENJI
IPC: H02K9/06
Filed: 1994-10-20
Abstract: PURPOSE: To lessen the contact heat resistance by welding a fin aslant so as to remove the space between the fin and the housing. CONSTITUTION: At the external surface of an induction motor composed of a fin 1 and a housing 2, the cooling fin 1 is fixed, being inclined by θ from the line passing the center to the circumferential direction from the center, and then welding is executed in axial direction. By having inclined the fin, the whole face of the base of the fin becomes a welding zone 4, and the space between the fin 1 and the housing 2 becomes small, and contact heat resistance decreases. As a result, effective heat radiation area increases, and the quantity of cooling increases. That is, even with the fin high in the height from the housing, high fin efficiency can be materialized by welding structure. Moreover, by inclining the cooling fin, even with the same motor diameter, the cooling system large in fin area can be materialized.

Abstract: PURPOSE:To produce thermo-elements as general purpose elements at a low cost, and to obtain the number of elements and the array of the same in accordance with the purpose of their use by forming a deformed part capable of deforming in the plane direction of an electrically conductive material between a P-type semiconductor and an N-type semiconductor in the electrically conductive material. CONSTITUTION:At the central part (between a P-type semiconductor 2 and an N-type semiconductor 3) of the longitudinal direction of a copper plate 4 is formed a reentrant part 5 being a deformed part. The reentrant part 5 is formed so that both ends of the short-side direction of the copper plate 4 are cut off in a circular arc shape at the central part of the longitudinal direction of the copper plate 4 having a rectangular shape. Since the width of the short-side direction of the copper plate 4 becomes narrow at the reentrant part 5 by forming the same in the copper plate 4 in such a manner, the bending of the copper plate 4 in a plane direction becomes possible. Accordingly, a number of thermo-elements 1 are consecutively connected to one another in a bar-like form and, by properly bending the reentrant part 5 of each of the copper plate 4, the thermo-elements 1 can be arrayed in various shapes such as a spiral array and a U-shaped parallel array in accordance with the purpose of using the same.

IPC: H04Q9/00
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To unnecessitate power supply from a commercial power source in the case of stand-by in electronic equipment while securing a means for restoration from any kind of situations by constituting a control means to control the on/off of a relay through the use of a remote control signal. SOLUTION: When the remote control signal 108 of power source off arrives at a receiving means 106 from a remote controller 107, the control means 105 turns off an internal power source switch 104 and becomes a charge waiting state. When the power storage amount of a power storing means 115 is judged to be sufficient by a power storage amount detecting means 116 in charging, it is regarded that the charging is ended, the relay 112 is turned off and a stand-by state is obtained. When restoration from a commercial power source restoration waiting state is detected by a commercial power source detecting means 131, the control means 105 turns on the relay 112 and the charge waiting state is obtained.  Thus, the power supply from the commercial power source is unnecessitated in the case of the stand-by in the electronic equipment while securing the means for restoration from any kind of situations.
