Title: Production of optical waveguide
Inventor: KOYAMA KENJI
IPC: G02B6/13
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To easily produce an optical waveguide having a core region of a desired width (more particularly a very fine width). SOLUTION: A glass film for the core is formed on a glass layer by a step S10 and an etching mask is formed on the glass film for the core by steps S11 and S12. The glass film for the core is etched by gaseous c-C4 F8 via the etching mask and the core region is formed by a step S13. At the time of the etching, the gaseous c-C4 F8 is cracked and C2 F4 which is radical species is formed. The polymerized film of the C2 F4 is adhered to the flank of the core region as well. The polymerized film acts also as a protective film against etching.

IPC: F25B1/00
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To curtail power during the stand-by time while accurately securing the protection of a compressor in the use of a long piping (multi-refrigerant) for separation type air conditioning equipment. SOLUTION: An inverter for driving a compressor and a compressor temperature sensor 6 are arranged in a refrigeration cycle in which a four-way valve, an outdoor heat exchanger, a capillary tube and a room heat exchanger are connected by piping to an electric compressor having a three-phase winding. A circuit is connected to the compressor temperature sensor 6 to allow switching thereof to a high resistance for low temperature or a low resistance for high temperature detection respectively comprising a resistance 22 and a resistance 23 and a transistor 24.  At the start of the operation of air conditioning equipment, a switching is made to the high resistance to detect a voltage and when the detected voltage is below a specified value, a uniphase power is applied to the three-phase winding of the compressor through the inverter and then, when the detected voltage reaches a specified value, the inverter is switched over to a three-phase output operation. Moreover, during the operation a switching is made to the low resistance and when the detected temperature reaches a specified value, the compressor is controlled to stop.

Title: Equipment with built-in teletext broadcasting decoder
Inventor: MIZUNO SHINGO
IPC: H04N5/57
Filed: 1994-01-14
Abstract: PURPOSE:To improve picture quality of box display by suppressing the contrast of an entire video image screen on which a box is displayed by teletext broadcast so as to suppress deflection distortion. CONSTITUTION:When a box display by teletext is designated, a contrast correction signal of an H level is outputted from a contrast correction signal output port 22. As a result, a potential level of a collector terminal of a contrast control signal amplification transistor(TR) 9 approaches a ground level and a voltage at a contrast control signal input terminal 14 of a video chroma circuit 3e approaches a ground level. The circuit 3e adjusts the contrast as a contrast control signal at the input terminal 14 decreases to reduce the luminance of the screen on which a box is displayed. Thus, the difference of lightness between a box display screen and a background screen is decreased and deflection distortion is suppressed.

IPC: G01J5/48
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To accurately judge whether an object is appropriate or not regardless of the atmospheric temperature of the object. SOLUTION: An object is line-scanned by a detector 2. A control part 4 compares a signal at this time with a threshold VTH for judging to see if the object is appropriate or not and outputs an alarm signal when the signal strength is equal to or more than the threshold VTH. At this time, the control part 4 extracts a signal that is regarded as a signal from a normal object out of signals from the detector 2, obtains the average of their strength, and determines the new threshold VTH based on the average. The new threshold VTH is used for the line scanning of a next object.

Title: Detecting method of negative resistance
Inventor: TAMATOSHI KUNIYOSHI
IPC: G01R31/26
Filed: 1982-02-03
Abstract: PURPOSE:To decide the presence or absence of negative resistance characteristics under desired conditions, by checking the generation of a relaxing oscillation phenomenon at both ends of an element to be evaluated when a capacitor is set in parallel to said element with application of a prescribed bias. CONSTITUTION:A prescribed bias current is applied to a constant voltage diode D3 via a DC bias power supply 1 and a resistor 2. A capacitor C8 is added in parallel to the diode D3. As a result, the relaxing oscillation is produced across the D3 when the negative resistance is generated at D3. Therefore the presence or absence is accurately detected for negative resistance characteristics of the D3 by monitoring the waveform of the D3 via a capacitor C9.

Title: Relay amplifier for bidirectional catv
Inventor: SHINODA SEIYA
IPC: H04B3/38
Filed: 1988-01-27
Abstract: PURPOSE:To simplify the system constitution and to improve the signal quality by controlling the gain of an incoming trunk line amplifier section and an outgoing trunk line amplifier section based on a cable attenuation calculated by either of the incoming/outgoing trunk line amplifier sections in a relay amplifier for bidirectional CATV compensating the cable attenuation. CONSTITUTION:Since the attenuation of a coaxial cable is expressed by an approximation formula using a frequency as a variable, a relay amplifier input level prediction value in an outgoing pilot signal and a required output level of the relay amplifier in the incoming pilot signal frequency are calculated. The calculation is implemented by a CPU 12 and the control voltage of a cable equivalent variable attenuator 5b in the incoming trunk line amplifier section 3b is outputted as a value quantized in several bits. Then the value is converted into a D/A converter 13 to generate a control voltage signal to a cable equivalent variable attenuator 5b in the incoming trunk line amplifier section 3b of the relay amplifier. Thus, either directional coupler in the outgoing amplifier section is not required and the signal quality is improved by the insertion loss of the directional coupler.

Title: Air circulating structure for outdoor unit for air bubble generating bath tub
Inventor: HARAGA HISATO
IPC: A47K3/10
Filed: 1990-01-28
Abstract: PURPOSE:To prevent storage of air having heat by means of a low capacity fan by disposing a fan, the discharge direction of which is down, in the upper position of a function part case, containing an electric device required for an air bubble generating bath tub, and in the vicinity of a transformer, and circulating air in the case. CONSTITUTION:Two fans F1 and F2 the discharge direction of which is down are disposed on the upper surface of a left middle stage shelf plate E3 in an upper position in a function case E, containing various devices, e.g. a circulating pump P, an insulating transformer Ti, an inverter I, and in the vicinity of an insulating transformer Ti. An air flow hole E5' is formed in the portion, near the inner wall of the case E, of a lower stage shelf plate E4, and air is caused to flow between upper and lower parts in the case. Thus, though heat air is apt to reside in an upper space by means of heat generated by the insulating transformer Ti and the inverter I on a shelf plate E1, the air is blown downward through the working of the fans F1 and F2. A part of the air is discharged through a gap W1 at a lower side wall, the rest is circulated in a space below the shelf plate E1 and flows upward through an air flow hole E5' of the lower stage shelf plate E4 to prevent storage of air having heat.
