Patent JP-S6139840-A (JP)
Title: 1-phase reluctance semiconductor motor
Inventor: BAN ITSUKI
IPC: H02K29/12
Filed: 1984-07-27
Abstract: PURPOSE:To increase the output torque by alternately flowing a currents through one and the other sets of exciting coils by the first and second position detection signals of a position detector. CONSTITUTION:When a rotor 2 is rotated clockwise, a coil 11 is separated from a salient pole 2a. Accordingly, exciting coils 4b, 4d are energized. Therefore, salient poles 2a, 2c generate different polarity by a magnetic induction, and the rotor 2 rotates clockwise by the attracting force. When rotated in the width of the salient pole, the coil 11 varies in the induction constant by the salient pole 2d. Thus, the coils 4a, 4c start energizing, and coils 4b, 4d stop energizing. Consequently, the salient poles 2d, 2b are attracted to electromagnets 3a, 3c in the same manner to subsequently rotate. Since the coils 4a, 4c and 4b, 4d are energized by the position detection output of the coil 11 as described above, it rotates as a DC motor.

Title: Rotary diffusion joining method and rotary diffusion joining apparatus
Inventor: SUSEI SHIYUUZOU
IPC: B23K20/00
Filed: 1978-12-14
Abstract: PURPOSE: To enable diffusion joining even in super-heat-resistant alloys, by setting a pair of members to be joined butt to butt with a soft metal layer inserted in the middle, rotating one member with respect to the other member, and keeping the heated pressurized state for a specified period of time.  
     CONSTITUTION: Soft metal layers 3, 3 of thin pieces of Ni, Cr or the like are formed on the surfaces of grooves 2, 2 of members 1, 1 to be joined (super-heat-resistant alloy). With one of the members 1, 1 secured, while rotating the other member at low speed so that the both joining surfaces on one side may be parallel, pressure is applied so that the soft metal layers 3, 3 may contact with each other, and at the same time the joining part is heated to high temperature by the rotary frictional heat. Thus, the members 1, 1 are joined together through the soft metal layer 3, then the rotation of the one member 1 is stopped. Next, under the specified joining temperature and pressure, the same state is maintained for 5 minutes to 14 hours to promote the diffusion between the soft metal layers and the members being joined, and a boundary layer 5 almost similar to the member being joined is formed in the joining part, and joining is completed.

Title: Semiconductor device adhesive film
Inventor: NAGAI AKIRA
IPC: H01L21/60
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To contrive to enhance reflow-resistant characteristics, by a method wherein, by use of a film material when adhering a wiring tape to a semiconductor element in an insulative manner, a specified modulus of elasticity is made in the reflow temperature region. SOLUTION: In a step of forming an external terminal 2.5 by a solder ball, etc., for connecting with a mounting substrate, or a solder reflow step for mounting a semiconductor element 2.3 on the mounting substrate, since a reflow temperature is processed at a high temperature of 200 to 250 deg.C, moisture is evaporated in a moisture absorbed semiconductor device, and a film material swells with the vapor pressure, with the result that a foaming atmosphere occurs, and defects such as voids, releasing, or the like occur. For this reason, as physical properties of an adhesive film material 2.2, a modulus of elasticity in a temperature region (200 to 250 deg.C) of mounting reflow conditions is set to be 1 Mpa or more. Thus, it is possible to enhance reflow-resistant characteristics.

Abstract: PROBLEM TO BE SOLVED: To prevent temperature increase in the cabin integrally structured with the reheated steam flexible inlet pipe for a high- to medium-pressure steam turbine with steam by cooling the steam by means of a double construction. SOLUTION: A cabin 11 is disposed of a main steam inlet pipe 14 and a reheated steam inlet pipe 1 that is integrally structured with the cabin 11. Main steam 30 flows from the inlet pipe 14 to a high-pressure turbine portion 17, reheated steam 31 flowing from the inlet pipe 1 to a medium-pressure turbine portion 19, both of which drive a rotor 12. Inside of the inlet pipe 1 has a circular groove 3 so as to form a double pipe portion 2. Bottom of the double pipe portion 2 has a enlarged diameter portion 4, made slidable in the vertical direction via a seal ring 6 along a flange 5 that is fixed to a thermal shield 21. Accordingly, thermal elongation is absorbed. Into the circular groove 3, low- temperature steam flows from a cabin space 23 through a hole (not shown in the figure).  Then, the steam is carried therein, flowing out to the steam passage of the medium-pressure turbine portion 19. This cools the inside, thus preventing temperature increase in the cabin 11.
