IPC: C03C13/04
Filed: 1986-01-27
Abstract: PURPOSE:To reduce an optical transmission loss being a radiant ray characteristic by specifying a ratio of an optical fiber diameter against a core diameter, of an optical fiber having a core consisting of pure quartz glass, and a clad formed by doping boron and fluorine in quartz glass. CONSTITUTION:The titled optical fiber has a core consisting of pure quartz glass, and a clad formed by doping boron and fluorine in quartz glass, and a ratio of an optical fiber diameter against a core diameter 1 is larger than 2.5. In this way, when the ratio of the core diameter and the optical fiber diameter is set within a specified range, an increase quantity (DELTAalpha) of an optical transmission loss at the time of irradiating a radiant ray can be suppressed at a room temperature to <=13dB/km at the time of irradiation of the radiant ray after, for instance, 10<4>R/HX60min, and an increase of this optical transmission loss becomes endurable enough for use under the existence of the radiant ray.

Title: Voltage controller
Inventor: KUNIEDA MASAMI
IPC: H02P27/02
Filed: 1979-02-15
Abstract: PURPOSE: To reduce the expense and weight of a voltage controller eliminating a three-phase transformer by insulating and controlling a power supply circuit through a photo coupler to connect the base of a control transistor to the power supply circuit.  
     CONSTITUTION: When a speed standard setting unit 16 produces a signal to a subtractor, the subtractor subtracts the signal by a signal from a signal converter 18 which rectifies and smooths the signal proportional to the speed of a three-phase induction motor 1 from a tachometer generator 17 coupled directly with the motor 1, and produces the difference to an error amplifier 15. Therefore, if the signal from the signal converter 18 is absolute value, the error amplifier 15 produces lowered output voltage, which is applied to a photo coupler 12. Thus, a large current IC will flow through the internal diode of the photo coupler 12, which thus irradiates increased light amount. Thus, the resistance value of a resistor is decreased. Accordingly, the base current IB of the transistor 10 is increased to lead the gate signal phase of a bi-directional thyristor. Thus, higher voltage is applied to the motor 1 to accelerate the speed of the motor 1.

Title: Video edition synchronizing device
Inventor: WATABE YASUHIKO
IPC: H04N5/91
Filed: 1995-02-02
Abstract: PURPOSE: To obtain a video edition synchronizing device capable of executing video edition by plural video recording/reproducing devices arranged on plural remote places by transmission. CONSTITUTION: On the master side, a synchronizing signal 7 for video edition is outputted from a synchronizing signal oscillating device 2 and applied to a video edition operating device (master) 1 for controlling a VTR-A and a VTR-C and a video transmitter (master) 3. The transmitter 3 encodes the signal 7 and transmits the encoded signal to a slave side arranged on a remote place through a transmission line 4. On the slave side, a video transmitter (slave) 5 decodes the encoded synchronizing signal and applies the encoded signal to a video edition operating device (slave) 6 for controlling a VTR-B as a synchronizing signal 8.  Since a synchronizing signal is transmitted to a remote place while preventing the generation of an error by encoding and plural VTRs arranged on respectively remote places are mutually synchronized, video edition among plural remote places can be attained by video transmission.
