Inventor: TERAOKA TATSUO
IPC: C03B37/014
Filed: 1991-01-25
Abstract: PURPOSE:To provide the method for producing an optical fiber preform so that rare earth elements may be uniformly distributed in the radial direction thereof. CONSTITUTION:The whole parent material 15 composed of a porous glass is immersed in a solution prepared by dissolving erbium chloride in ethyl alcohol and allowed to stand for about 2hr to sufficiently impregnate the parent material 15 composed of a porous glass with the solution. The parent material 15 composed of a porous glass is subsequently pulled out of the solution surface at a rate of about 5mm/min. While pulling up the parent material 15 composed of a porous glass, the solvent contained therein is evaporated by a hot air heated by a heater 13 and the parent material 15 composed of a porous glass is dried. Sintering is then carried out to form a transparent glass, thus obtaining the objective an optical fiber preform.

IPC: B65G47/52
Filed: 1989-02-02
Abstract: PURPOSE:To provide automated control over averaging of amount of large-size refuse to be conveyed by combining two apron conveyors and controlling the operation of an upstream conveyor in such a manner that the amount of refuse yet to be conveyed on a downstream conveyor is kept constant in an apron conveyor system for feeding large-size refuse into a crusher. CONSTITUTION:A second apron conveyor 2 is operated either continuously or intermittently through control of current value of a crusher 8. The amount of refuse at a transfer section 4 between first and second apron conveyors 1, 2 detected by a detector 5 installed near the transfer section 4.

Title: Film rewinding device
Inventor: KIMURA HIROYUKI
IPC: G03B17/00
Filed: 1981-02-24
Abstract: PURPOSE:To prevent a sudden film rewinding action for a camera in which the film is wound preliminarily and then rewound every a frame, by providing a switch coupling to the pushing of a release button to the film rewinding electric conduction path. CONSTITUTION:When a film is not loaded yet, the switches 40' and 40'' are munually switched to the side of a terminal (b) after the film is loaded and wound preliminarily. A switch 44 is closed by a releasing action, and a switch 45 is closed (with a switch 45' opened) in coupling to the end of exposure. Thus a motor winds the film by a frame, and the switches 45 and 45' are closed to stop the motor quickly. As a result, the sudden actuation of the motor is avoided even though the power supply is replaced while the film is rewound. Thus no failure is caused in shooting at a place requiring a quiet atmosphere.

Filed: 1992-01-16
Abstract: PURPOSE:To shorten unstable operating time both at the time of transmission and reception by providing a circuit selecting an output from a frequency synthesizer with a transmission/reception switching signal from a switching timing control circuit and a transmission mixer. CONSTITUTION:An output signal from the frequency synthesizer 9 whose frequency is fL is inputted to a reception mixer 5 via a switching circuit 10 in the case of reception. Moreover, the output signal from the synthesizer 9 whose frequency is the same as the frequency fL at the time of the reception is inputted to a transmission mixer 12 whose other input receives a signal from a local oscillation circuit 11 via the circuit 10 in the case of the transmission.
