Inventor: KAGE ISAMU
IPC: C22C38/00
Filed: 1994-12-20
Abstract: PURPOSE: To provide an Fe-Ni base alloy excellent in the etching workability. CONSTITUTION: The Fe-Ni base thin sheet, in which the max. value of Ni content on the surface layer part does not exceed 1.10 times of the average Ni content thereof, is prepared.

Abstract: PURPOSE:To improve the resolution by obtaining two logical signals having a period of 1/2<n-2> (n is an integer >=4) of a moving period of a slit of a moving slit plate, and being 90 deg. out-of-phase to each other. CONSTITUTION:When a moving slit plate 3 moves by a 1-pitch portion of a slit 11, a moire fringe moves by 1 pitch in the Y direction, and respective photodetectors 20a-20h output a current corresponding to the variation of the irradiating light quantity.

Filed: 1990-11-20
Abstract: PURPOSE:To recover the talking with an opposite party in talking on the occurrence of a fault quickly by making dialing based on a telephone number in talking when the fault is recovered after the detection of the occurrence of the fault in a radio transmission line by a fault detection means. CONSTITUTION:When a level of a signal received by a reception section 3 is decreased to be a prescribed level, a detection signal from a level detection section 15 being a fault detection means is fed to a control section 7. The control section T transits to a fault processing from the normal control based on the detection signal. Whether or not the fault is excluded in the fault processing is discriminated based on the restoration of, e.g. a reception electric field strength and when the fault is excluded, the restart of the communication with the base station is implemented, When the radio line with the base station is established, whether or not a telephone number of a preceding talking destination is known is discriminated and when it is known, redialing is implemented based on the number. Thus, the talking with a destination in talking on the occurrence of the fault is quickly restarted.

Filed: 1992-11-26
Abstract: PURPOSE:To ensure the operation of change logic without being conscious about the presence of terminating resistors by examining the excess and shortage of the terminat ing resistors of the change logic, selecting the reserve terminating resistor at the optimum position on a chip when the resistors are in short, automatically adding the resistor into the change logic, and automatically generating the logic for cutting the unnecessary terminating resistors when the resistors are excessive.

When the terminating resistors are in short, the terminating resistor is selected among reserve terminating resistors, which are prepared on a chip, and the selected terminating resistor is connected. This logic is generated based on a wiring path information file 514 and a mounting--information/logic-information file 512. When the terminating resistors are excessive, the terminating resistor is selected among the excessive terminating resistors, and the connecting wire, to which the terminating resistor other than the selected terminating resistor is connected, is cut. This logic is generated based on the wiring- path information, the mounting information and the logic information.

IPC: H01S5/00
Filed: 1987-12-15
Abstract: PURPOSE:To obtain high optical coupling efficiency stably for a long period by interposing an annular solder layer between a flange and a mount base, and projecting laser light and fusing the solder layer. CONSTITUTION:The annular solder layer 5 is interposed between the flange 2 and mount base 4 and the laser light is projected along the flange 2 to fuse the solder layer 5. Thus, the laser light is projected along the flange of a lens holder, e.g. as shown by an arrow to fuse the solder layer, so a solder zone is heated uniformly. Residual heat stress is prevented from being generated at the part. Consequently, a creep is prevented from being generated in solidified solder and the optical coupling efficiency is prevented from varying with time.
