Title: Disk film projecting device
Inventor: NAKAYAMA YOSHIAKI
IPC: G03B21/10
Filed: 1983-08-29
Abstract: PURPOSE:To obtain a disk film projection device which facilitates the loading and unloading of a disk film and is mechanically simple by utilizing the stable mechanical force of a spring, etc., to load and unload the disk cartridge. CONSTITUTION:When the cartidge 400 is pressd down in the opposite direction of an arrow C while inserted into the recessed space 212 of a holding member 208, an abutting member 282 moves down against the spring 294 to lower an arm 284 and a link 286, and an arm 272 rotates counterclockwise around a shaft 270. A apindle 214 is energized with the spring as shown by an arrow B, so the roller 264 of a manual operation member 256 which is on the lower surface 276 of the top surface 274 of the arm 272 so far moves to the higher surface 278 beyond its hook type part, pressing the arm 272 continuously. This pressing force is larger than the repulsive force of the spring 294, and various constants such as the spring constants of springs 254 and 294 and the shape and position of the higher surface 278 are so set that the roller 264 does not rotate in the opposite direction of the arrow B, thereby holding the cartridge 400 at a position shown in a figure.

Filed: 1994-06-16
Abstract: PURPOSE:To obtain a rigid and small-sized acceleration converter having high natural frequency and strain output sensitivity and excellent in long term stability, hysteresis characteristics and creep characteristic in which the assembling work and repairing work are facilitated. CONSTITUTION:The acceleration converter comprises a cantilever beam 3 comprising a driven part 3a, a flexible part 3d, and a weight part 3e, a pair of reinforcing membranes 4, 5, insulating films 6, 7, four strain gauges SG1-SG4, and a casing 1 (with cover 1a).

Abstract: PROBLEM TO BE SOLVED: To reduce the number of components and to improve waterproofing performance. SOLUTION: A press-contact blade 22B is formed on a terminal fitting 20, a sealing member 40 is mounted to a press-contact base 30, the sealing member 40 is threaded with wires W, and then, the press-contact base 30 is mounted to a socket body 10 (housing).

Filed: 1992-06-16
Abstract: PURPOSE:To realize a device preventing mis-judgment even when S/N becomes wrong and having a privacy function by selecting the format of interleaving operation with a cipher code and selecting the format of inverse-interleaving operation with a decipher code. CONSTITUTION:When by an interleaving means 2, convolution coded data is interleaved with various kinds of formats, the format is selected by the cipher code from a cipher code input means 3 and recorded through a write amplifier 4. Further, at a reproducing time, a regenerative signal amplified by a read amplifier 5 is inverse-interleaved with various kinds of formats by an inverse- interleaving means 6. In such a case, the format is selected by the decipher code from a decipher code input means 7 and by a maximum likelihood decoding means 8, regenerative data is decoded while being error-corrected by a maximum likelihood decoding method. Thus, the mis-judgment due to viterbi equalization is prevented even when the S/N becomes wrong and the privacy function is effective for a person who knows no decipher code.

Title: Supercharging device for internal-combustion engine
Inventor: TAKAHASHI HIDEO
IPC: F02B37/18
Filed: 1983-08-30
Abstract: PURPOSE:To check an operation delay in a supercharger in time of acceleration, by sensing an abnormal rise in supercharging pressure at the downstream side of a compressor, while cutting off operating signal pressure of a suction relief valve, and opening the suction relief valve directly with the supercharging pressure that rises so abnormally. CONSTITUTION:At anything trouble in an exhaust bypass valve 26, when this valve 26 opens and thereby supercharging pressure rises so abnormally, a pressure switch 45 senses the supercharging pressure inside a suction air passage 32 and is turned to ON, causing a three-way solenoid selector valve 42 to be energized with current and excited, and pressure inside a pressure operating chamber 41c is opened to the atmosphere. Force in the valve opening direction of a suction relief valve 41 turns to only the elastic force of a spring 41d whereby it comes to no relation with the downstream pressure of a suction throttle valve 33. Accordingly, the supercharging pressure inside the suction air passage 32 acts on the pressure receiving part of a valve body 41a, thereby opening the suction relief valve 41.

Title: Semiconductor laser device
Inventor: SATOU KENICHI
IPC: H01S5/065
Filed: 1979-12-06
Abstract: PURPOSE:To lower the coherence of a semiconductor laser by a method wherein one section of light projecting from the semiconductor laser is fed back to an active layer of the semiconductor laser by using an optical fiber and a reflecting surface with constant reflexibility. CONSTITUTION:An optical fiber 9 for a transmission path is connected to one end surface of a semiconductor laser 1 with a laser active layer 2, and an optical fiber 3 with a reflecting surface 5 formed so as to have constant reflexibility to semiconductor laser rays is connected to the other end surface.

The width of an oscillating spectrum of the semiconductor laser is expanded by the feedback, a distance of the coherence of the semiconductor laser is shortened (coherence is lowered), and the deterioration of a transmitting characteristic and a noise characteristic is reduced.
Patent JP-H0322114-A (JP)
Title: Controller
Inventor: KIMOTO EIJI
IPC: G05D3/12
Filed: 1989-06-20
Abstract: PURPOSE:To smoothly change a load position by preventing an internal speed command from being switched until the output of an integrator comes near to load speed when a selector switch is turned off. CONSTITUTION:When a selector switch ON signal 20 is disconnected, at first, an internal speed command selector switch 17 is turned off through a logical circuit 19, and a speed command selector switch 8 is left as it is ON. The internal speed command 15 becomes larger gradually by integrating a speed error 14 by the integrator 4 by a fixed time constant. Since the time constant of the integration is fixed, when the selector switch ON signal 20 is disconnected, the selector switch ON signal 20 is inputted to the logical circuit 19 as delaying the signal by the time constant of the integration by a time constant circuit 18. On this signal, the logical circuit 19 outputs the signals, respectively to turn on the internal speed command selector switch 17 and turn off the speed command selector switch 8. Thus, as for the input of an internal speed loop computing element 5, the internal speed command 15 is inputted when the internal speed command 15 comes near to load speed 13, and the speed command 12 is disconnected, and the load position 10 never operates unstable operation.
