Title: Optical amplifying device
Inventor: INOUE YASUSHI
IPC: H04B10/00
Filed: 1987-06-15
Abstract: PURPOSE:To contrive the improvement of the gain being free from the polarized wave dependency, by synthesizing each output of a first optical amplifier and a second optical amplifier by an optical multiplexer to output it. CONSTITUTION:A light beam inputted to optical semiconductor laser beam amplifiers 15, 16 is always arranged so that the polarized wave direction of an input light becomes the TE polarized wave direction of the amplifier, as a polarized wave in the prescribed direction, and so that the input light receives the prescribed and maximum gain. The light beam which has been amplified by the optical amplifiers 15, 16 passes through propagation paths 17, 18 and inputted to an optical multiplexer 19. In this state, the propagation paths 17, 18 hold the polarized wave direction of the propagated light beam in the same way as propagation paths 13, 14. An optical polarized wave separating device has a function for outputting two orthogonal polarized wave light beams which have been inputted, to match one optical path, therefore, the input light beam from the propagation paths 17, 18 are synthesized and outputted to a propagation path 21 of a light beam. In such a way, a device whose gain does not depend on a polarized wave state of the input light is obtained.

Title: Power line carrier controller
Inventor: TANAKA OSAMU
IPC: H04L7/00
Filed: 1982-08-31
Abstract: PURPOSE:To attain long-distance transmission with a decreased carrier frequency and to synchronize surely transmission and reception, by transmitting a signal with a synchronizing signal having a frequency 3 times the frequency of a zero cross pulse, setting a reference clock signal having a cycle three times that of the zero cross pulse as a basic signal of a timing signal and setting a carrier frequency to 1/3 of a conventional frequency. CONSTITUTION:An output of a zero cross detecting section 37 is frequency-divided into 1/3 at 1/3 frequency division circuit 38, inputted to a main body circuit section X as a clock input, an output of a carrier wave generating section 39 is frequency-divided to 1/3 at a 1/3 frequency divsion circuit 40 and inputted to a modulation/demodulation section 13 to set the carrier frequency to 1/3 of the conventional value. The time counting the carrier frequency is triplicated by setting the frequency of a reference clock of the circuit, and the reliability of signal transmission is not deteriorated by setting the carrier frequency to 1/3 for long-distance transmission, Since the frequency of the reference clock is decreased to 1/3 as the synchronizing signal as mentioned above, the quality of transmission is not lost even if the carrier frequency is divided into 1/3, and the carrier frequency is reduced and the distance of transmission is extended.

Filed: 1982-08-31
Abstract: PURPOSE:To prevent such a trouble that static electricity is generated on a film during rewinding operation, by making the film rewinding speed of a motor- driven camera lower than the film advancing speed. CONSTITUTION:A film winding and rewinding motor 3 is applied with a voltage from power batteries, nearly as it is, through a transistor (TR)T1 and a switch S2 connected to a terminal side W during winding operation. For rewinding operation, a Zener diode ZD is connected between the plus side of the motor 3 and the base of a TRT3 through the switch S2 connected to a terminal side RW and the TRT3, so the motor is applied with a voltage obtained by subtracting a constant voltage drop across the TRT3 from the battery voltage to rotate at a lower speed than during the film advancing operation. Thus, picture planes are prevented from damaging owing to the generation of static electricity on the film.

Abstract: PURPOSE:To facilitate assembly and prevent falling off by arranging a cushion member along a separate block face facing a vane and inserting its both end parts to a fitting hole of a cylinder body and a fitting hole of a cylinder cover respectively. CONSTITUTION:When rotational movement is applied to a shaft 9, a vane body 16 rotates in the inside of a casing 5, so that a volume of one of oil chambers 19a, 19b is shrunk while a volume of the other is expanded vanes 18a, 18b. In this way, a hydraulic oil flows through a gap around the vane body 16 from a hydraulic chamber shrunk side to a hydraulic chamber expanded side, so that damping force is generated by its flow resistance. When an amplitude for the rotational movement is increased, the vanes 18a, 18b are brought into contact with the cushion members 20a, 20b to compress them. Therefore, the vanes 18a, 18b are prevented from colliding with separate blocks 7a, 7b. Even when compressing action for the cushion members 20a, 20b are repeated, they do not fall off, as their both ends are held by engaging holes 3c, 4c, 3d, 4d of a body 3 and a cover 4. Assembly can be carried out only by fitting the cushion member to the engaging holes.
