Title: Input device for finger print information
Inventor: HANARI ATSUSHI
IPC: G06T1/00
Filed: 1990-02-26
Abstract: PURPOSE:To find out one-dimensional finger print information without requiring complicate signal processing by converging reflected light from a transparent surface on which a finger impressed in one direction and detecting the converged light by an optical sensor. CONSTITUTION:The finger-impressed face of a transparent body 11 is irradiated with light projected from a light source 13. Since the light is dispersed on the projected parts of the finger print and reflected on the recessed parts, a finger image signal can be obtained from the reflected light as two-dimensional information. The reflected light is linearly converged in the longitudinal direction of the finger by an optical element such as a cylindrical lens 15, the optical addition of the finger print information is executed and the finger print information is obtained by the one-dimensional optical sensor 16 as an electric signal. Consequently, a signal similar to a signal obtained by adding a signal to a finger print signal obtained as two-dimensional image information and forming an one-dimensional signal can be more simply obtained.

Title: Bar code reader
Inventor: SAEGUSA SHINJI
IPC: G06K7/10

Title: Frequency control laser device
Inventor: WAKABAYASHI SATOSHI
IPC: H01S3/131
Filed: 1983-03-15
Abstract: PURPOSE:To make a cheaper and delayed-response detector suffice a detector required for the titled control while miniaturizing signal processing circuit by a method wherein either oscillation frequency of a main laser oscillator or resonance frequency of a sub laser oscillator is frequency-modulated by a low frequency. CONSTITUTION:Output beams of a main laser oscillator 1 are emitted into a sub laser oscillator 7 to make transmitting light thereof enter into a detector 5 after being reflected by a polarized wave separator 14. The output beams of the main oscillator 1 are amplitude-modulated by transmission characteristics depending upon a resonator of the sub laser oscillator 7. The modulated frequency of the amplitude modulation becomes fs since the resonance frequency fpx of the resonator is modulated by a frequency fs. When this modulated frequency fs converted into electric signal by the detector 5 is input into a lock-in amplifier 15 to be synchronously detected by signal of a reference signal source 12, an error signal to tune fpx to fm is received making fpx=fm. Consequently, the oscillation frequency fm of the main laser oscillator 1 and the other oscillation frequency of the sub laser oscillator 7 may be controlled subject to specified frequency difference since the frequency difference may be decided by thickness and refractive index of a double refractive crystal 11.

Title: Preparation of glass fiber
Inventor: TAKE HIROMASA
IPC: C03B37/022
Filed: 1980-04-04
Abstract: PURPOSE:To prevent the difficulty in starting the operation in restarting the rotation of a collet in preparing glass fibers by winding many molten glass streams onto the collet, by pulling the glass streams at a low speed while cooling the streams with air in the stopping of the collet rotation. CONSTITUTION:Many molten glass streams flowing out of a bushing are wound onto a collet rotating at a high speed to prepare glass fibers. In the process, the molten glass streams are cooled suitably with a high-speed air current formed around the streams. If the rotation of the collet is stopped by an accident, etc., the cooling of the molten glass streams becomes insufficient, and the streams flow of the bushing in the form of inverted spindles to make the drawing impossible. Therefore, glass fibers are pulled at a low speed while being cooled with a cooling air current directed to the bushing. The molten glass streams from the bushing are not broken and returned to the normal state in restarting the rotation of the collet. Thus, the stopping of the operation due to the stopping of the collet rotation will not occur.

Title: Tritium recovering device for nuclear fusion reactor
Inventor: OBARA ATSUSHI
IPC: G21B1/11
Filed: 1994-03-15
Abstract: PURPOSE:To recover tritium in a hydrogen molecule-like state so as to reduce the inventory of tritium by providing a supplying means which supplies hydrogen isotropic molecules other than tritium, isotope exchanging means, separating means for separating hydrogen isotopic molecules, and supplying means which supplies the dust reduced component of tritium to a purge gas. CONSTITUTION:The tritium produced from the blanket 5 of a nuclear fusion reactor is carried away from the blanket 5 on a purge gas composed mainly of helium. The tritium which is discharged in a steam-like state is converted into a hydrogen molecule-like component through reactions, T2O+H2 HT+ HTO and HTO+H2 HT+H2O in an isotope exchanger 12 filled with a catalyst by adding an excessive amount of hydrogen isotope into the purge gas. The hydrogen isotopic molecules containing tritium are separated from the purge gas by using a palladium film separation column 13. When such a tritium recovering device is used, the inventory of tritium can be reduced, because the recovering process is performed through the vapor phase reactions and no adsorbing process is involved.
