Title: Device for controlling changeover of power supply for ac electric railway
Inventor: MOCHINAGA YOSHIFUMI
IPC: B60L9/30
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a device for controlling the changeover of power supplies for AC electric railroads capable of limiting overcurrent at the time when a changeover switch at the terminal station side is closed. SOLUTION: This device is provided with a starting station side changeover switch 4 and a terminal station side changeover switch 5 connected parallel at a neutral section 3 where different power supplies are matched comprising a starting station side power supply 1 and a terminal station side power supply 2. By feeding power to a transformer provided inside an electric car 6 from either of these power supplies 1, 2 by alternately changing these changeover switches 4, 5, this device makes it possible to drive an auxiliary electric motor connected to the transformer. In this case, when the electric car is on the line of the neutral section 3, residual flux of the transformer inside the electric car 6 immediately before the changeover of the power supplies and its stable flux after the changeover are each calculated.  A flux calculating means 10 is also provided which gives a closing command to the terminal station side changeover switch 5 when the difference between the calculated values is within a permissible range.

Filed: 1984-04-14
Abstract: PURPOSE:To contrive an improvement in safety of work and efficiency, by constituting a magnet so that it is stickable to an uneven surface of a wall surface in a connecting state. CONSTITUTION:When an electromagnet 22 is excited, the electromagnet is stuck to a membrane wall 30 against a tension spring 35.

Title: Optical system and optical device using long frequency spectrum molding device
Inventor: ASHISHIYU MADOHAAKAA BUENGUSAA
IPC: H04B10/43
Filed: 1995-03-31
Abstract: PURPOSE: To remove unused excitation energy in a fiber amplifier by providing a long-period spectrum forming device which shifts light of unnecessary wavelength from a guided mode to a non-guided mode. CONSTITUTION: An optical fiber 10 has a core 11 enclosed with a clad 12 having a low refractive index. The core 11 includes one or more long-period gratings 13, and each grating includes plural refractive index perturbations 14 which are separated by a period distance Λ and have a width (w). These perturbations are formed in the glass core of the fiber and, preferably form an angle θ(2 deg.<=θ<=90 deg.) to the major axis of the fiber. This fiber is so designed that wide band light with about λ as the center wavelength is transmitted. The interval Λof these perturbations shifts transmitted light in the area of a selected wavelength λp from the guided mode to the non-guided mode, and as the result, the intensity of light in the band with the wavelength λp as the center is reduced.

IPC: H01H33/66
Filed: 1990-03-23
Abstract: PURPOSE:To enable monitoring of vacuum leakage at all by finding a degree of vacuum of a vacuum valve via insulating optical fiber. CONSTITUTION:A degree of vacuum of a vacuum valve inside 5 is detected in accordance with a correlation to control current which keeps the temperature of a black substance 6 located in the valve at a constant value. The black substance 6 is heated by receiving light from a light emitting device 12 which is located on a vacuum valve outside 11 via optical fiber 15, a light air-tight terminal 14, a converging lens 18, and resulting emitted light 9 is sent to a light receiving device 13 via a wavelength converting element 20, a light guiding element 10, the light air-tight terminal 14 and the optical fiber. The control device 16 sends control current 16A to the light emitting device 12 to keep the black substance 6 at a constant temperature. If a correlation between the control current 16A and a degree of vacuum is previously corrected, a degree of vacuum of vacuum equipment which is set in an operating state can always be detected.

Abstract: PURPOSE:To maintain high reliability for a long period and to detect dew condensation by detecting the dew condensation by using light beams in the 1st and the 2nd wavelength bands which differ in transmissivity to water. CONSTITUTION:Light emitted by the 1st light emitting body 1a reaches a light reception part 3 while attenuated by the absorption by water (dew) on a dew condensation surface 2 and scattering due to dirt, etc. Light emitted by the 2nd light emitting body 1b, on the other hand, reaches the light reception part 3 after being attenuated by only the scattering due to the dirt on the dew condensation surface 2 almost without being attenuated by the water.

Abstract: PURPOSE:To obtain a deep-sea ultrasonic transducer array with high reliability by removing a multicore cable solidly molded together with a vibrator array and containing its signal lines in a booth filled with acoustic oil together with the vibrator array. CONSTITUTION:A signal line 9 of a vibrator array 6 contained on a housing case 10 is connected to a terminal 15 of a terminal board fitted on a case 13 as well as to a terminal 16 of a terminal board 18 through an electronic circuit 14. Then the housing 10 is contained in a booth filled with an oil 12, is mounted on a fitting groove of the case 13 and fixed securely on the case 13 with a band 21. If a deep-sea ultrasonic wave transducer array assembled in such a way is descended under high hydraulic pressure, the tensile strength caused by the pressure difference is not applied to the signal line 9, and troubles such as disconnection are not raised on the signal line 9 accordingly. Furthermore, since excessive force is not applied to each signal line 9, said transducer array can be stably descended in the sea water.
