Title: Detection of fault of rectifier element of ac exciter for brushless synchronous machine
Inventor: OBARA TAKASHI
IPC: H02K19/36
Filed: 1986-12-24
Abstract: PURPOSE:To automatically separate a troubled rectifier and to remotely detect the fault of the rectifier by means of a composition to supply power to a switch mechanism, using shape memory alloy characteristics and auxiliary wirings, and a display mechanism in combination. CONSTITUTION:When a rectifier 11 becomes troubled, an abnormal current flows to AC lead 14, which is resultantly overheated. A shape memory alloy 21 receives the heat to be deformed to an originally set state, a bimetal mechanism 22 is short-circuited, and an exciting current from a power source line 17 flows to the solenoid 23a of a solenoid switch 23. When the solenoid 23a is energized, its contact 23b is opened to eliminate the supply of an AC power to the troubled rectifier 11. Simultaneously, a display 25 in a display mechanism 15 operates to display the fault.

Title: Cutting by multisaw
Inventor: IKEDA KAZUHISA
IPC: B28D5/00
Filed: 1987-12-11
Abstract: PURPOSE:To obtain a wafer having a uniform thickness without generating the tilt of a number of bands by attaching these bands onto the top point of a platen plate fixed onto a testpiece board and cutting a part of the upper part of the platen plate in parallel and contacting the plate to an ingot fixed onto the testpiece board. CONSTITUTION:When a testpiece board 4 is raised by a weight 6, a number of bands 41, 42,... are attached onto the top surface 8 of a platen glass 3. When the bands 41, 42,... are moved in reciprocation, these bands 41, 42,... cut the top surface 8 of the platen glass 3 in the mutually parallel state at the same time. Then, a certain band is fixed onto the testpiece board 4, and contacts the surface of a compound semiconductor single crystal ingot 2 manufactured through the HB method, and starts to cut the ingot 2. Since, in this case, the testpiece board 4 is lifted up by the weight 6, the contact pressure does not concentrate onto the band, and the contact pressure is applied in dispersion also onto other bands, too. Therefore, these bands in parallel state cut the ingot 2, and a wafer having a uniform thickness can be cut out.

Filed: 1989-12-07
Abstract: PURPOSE:To allow a large number of images to be observed by varying the display speed of the image having information quantity exceeding the through- put a communication line or channel, and that of the image not exceeding it in real time. CONSTITUTION:The images 243, 244 of plural hierarchies from which the picture elements of an original image 22 are thinned are registered on an image data base 21 with the original image, and when the user of an image display terminal 1 requests the continuous display of the image at speed exceeding the throughput of the communication line or channel 3, an image data base center 2 transmits the image with the hierarchy of thinning rate corresponding to it continuously. When a request to vary the display speed is issued within a range of throughput, the original image is transmitted as it is, and the continuous display of the image is performed by taking a timing at a terminal side fitting in the request when transmission via the communication line is performed, and by taking the timing at a center side when it is performed via the channel. In such a way, it is possible to observe a large number of images in a short time, and to search a specific image out of a large number of images in a short time.
