Title: Formation of electronic circuit
Inventor: CHIYOU KOUYUU
IPC: H01L21/316
Filed: 1993-02-22
Abstract: PURPOSE:To uniform the oxidation rate of a surface, and obtain an uniform oxide film of little unevenness, by performing anodizing oxidation in the state that the temperature around a metal wiring kept lower than or equal to 10 deg.C, preferably, 0 deg.C. CONSTITUTION:Wirings 14a, 14b are formed by patterning an aluminum film formed on a substrate 10. Tartanic acid is dissolved in ethylene glycol and neutralized by adding ammonia aqueous solution. The solution is cooled at -8-+2 deg.C, in which the wiring 14a, 14b are subjected to anodizing oxidation by passing currents through them. Thereby aluminum oxide films 16a, 16b of 1500-3000Angstrom  in thickness are formed. After impurity regions 17a, 17b are formed by a plasma doping method, activation is performed by a laser annealing method. A silicon oxide film 18 of 3000Angstrom  in thickness is formed as an layer insulating film by a plasma CVD method. After a contact hole is formed, wirings 19a, 19b are formed by using a mulitayered film of titanium nitride and aluminum. Since an uniform anodic oxide film can be obtained, electric characteristics are improved.

Title: Capacitor charging circuit
Inventor: TABUCHI SADATOSHI
IPC: G05F1/56
Filed: 1984-03-23
Abstract: PURPOSE:To increase the back-up time in case no electric charge is stored in a capacitor for back-up by using a constant current to charge said capacitor. CONSTITUTION:The voltage of a commercial power supply 1 is turned into the DC voltage by a DC power supply 2 and used as the power of an electronic circuit 11. While transistors Tr15 and 16 of a zero-volt generating circuit 12 are turned off at a level near zero voltage of the power supply 1 by resistances 13 and 14 or either one of both Trs is turned on. Thus a zero-volt pulse is generated and supplied to a charging current supply circuit 17. A current flows to a resistance 18 only while said pulse is not produced, and a fixed level of voltage is produced at both ends of a constant voltage diode 19. Therefore a constant current IE flows to a resistance 21 and is used as a charging current of a capacitor 9. While no current flows to the resistance 18 at a level near zero voltage of the power supply 1 and in a service interruption mode. Thus a Tr20 is turned off and the charging of the capacitor 9 through the circuit 17 is stopped. In such a way, the waste of electric charge of a capacitor 5 is prevented by the current IE when no charge is stored in the capacitor 9. As a result, the back-up time of the circuit 11 is increased.

Title: Internal spawn detecting device
Inventor: NISHIGAKI MORIO
IPC: G01N29/00
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To enable the high-speed and highly accurate detection of the presence or absence of internal spawns by radiating ultrasonic pulses toward the abdomen of a living body and analyzing their reflected echoes. SOLUTION: A transmitting circuit 1 outputs transmission pulses to a probe 2 under the control of a control circuit 8, and the transmission pulses are converted to ultrasonic pulses at the probe 2 and radiated toward a moving fish body 3. Ultrasonic waves are reflected at the internal organs, fish spawns, etc., in the fish body 3 and inputted to a signal processing circuit 6 via the probe 2 and a receiving circuit 5. In the transmission and reception of the ultrasonic pulses, transmission pulses are generated as changing the location of the fish body 3, and data storage in a signal processing circuit 6 is performed a few times to tens of times. Location information on these capture is detected by a sensor 9 and stored. Echoes incorporated in a pulse echo method such as this are displayed in hierachically structured images and observed as images.  As the result of this signal processing, the presence or absence of fish spawns is determined, information on this determination is sent from the control circuit 8 to a sorter 10, and the fish body 3 is sorted by the presence or absence of fish spawns. In addition, at the time when the presence or absence of fish spawns is indefinite, the sorter 10 sorts into tree categories; fish spawns present, fish spawns absent, and indefinite.

Title: Stored coin discrimination device for coin processor
Inventor: KIMOTO TOYOKI
IPC: G07D1/00
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To make a machine body compact by discriminating a coin of a different denomination in the case that a minimum value of detection data detected by a magnetic detection means, which is provided in such position that a coin fed out from a coin storage cylinder can be detected, is within a range of reference coin data other than the denomination corresponding to the coin storage cylinder. SOLUTION: The magnetic detection means consists of a detection coil 7, an oscillator 11, a receiver 12, an amplifier 13, a DC converter 14, and an A/D converter 15. A detection data storage means consists of a ROM 18. The magnetic detection means which is provided in a position so as to be able to detect a coin fed out from the coin storage cylinder and detects the magnetic property of the detection object compares detection data for detection of the fed-out coin with reference coin data of the denomination corresponding to the coin storage cylinder which is stored in a detection data storage means. If detection data doesn't coincide with reference coin data of the denomination corresponding to the coin storage cylinder, this coin is judged to be a coin of a different denomination. Consequently, a constitution for detection of coins of different denominations is minimized.

Title: Optical directional coupler
Inventor: AKITA OSAMU
IPC: G02B6/122
Filed: 1989-03-09
Abstract: PURPOSE:To greatly decrease crosstalks and to provide the optical directional coupler having a high extinction ratio by forming recesses on the surface of a substrate in the part before and after the coupling part between plural light guides formed on the substrate. CONSTITUTION:A Ti film is deposited by evaporation on the substrate 3 and is formed with two pieces of the light guides 1 and 2 by etching, following which the film is subjected to thermal diffusion and thereafter, the recesses 7 and 8 are formed before and after the coupling part 4 by reactive ion etching to a triangular shape along the light guides 1 and 2. There is no medium to propagate light except an air layer which is much smaller in refractive index than the light guides between the plural light guides 1 and 2 before and after the coupling part 4 formed in such a manner. The light guides 1, 2 are, therefore, optically and completely separated before and after the coupler 4. Since the light propagating in one light guide does not shift into the other except in the coupling part 4. The extinction ratio is thus improved.
