Title: Method for controlling freezing compressor
Inventor: HANAWA IZUMI
IPC: F25B1/00
Filed: 1991-02-14
Abstract: PURPOSE:To improve durability in an entire compressor by a method wherein a driving operation of each of the limited number of freezing compressors only is carried out and as regards the remaining freezing compressors, a transmittance of a driving force of each of them is released. CONSTITUTION:A counter starts to count the number of starting times of a compressor concurrent with its starting operation. In the case that the counted value is an odd number, only a clutch A is turned ON to perform a load driving of a compressor 40A. When a temperature within a refrigerator chamber is less than a changing-over temperature under this load driving, a clutch B is turned ON to cause compressors 40A and 40B to be driven under a load and they are transferred to their normal operations. In the case that the counted value is in an even number, the clutch B is turned ON, thereby the load operation of the compressor 40B is carried out. When the temperature within the refrigerator chamber is less than the changing-over temperature under the load driving operation, the clutch A is turned ON to cause the compressors 40A and 40B to be driven under load and they are transferred to their normal operations. With such an arrangement as above, it is possible to improve durability of the entire compressor device.

IPC: H01M4/90
Filed: 1982-03-15
Abstract: PURPOSE:To obtain a gas-diffuson electrode for a battery which is made of a low-cost highly-active catalyst layer by preparing the catalyst layer from a mixture which contains active carbon and a manganese oxide which is produced by allowing manganese sulfate solution to react with potassium chlorate under an acidic condition. CONSTITUTION:A manganese sulfate solution is acidified with sulfuric acid or nitric acid. Thus, acidified solution is mixed with potassium chlorate, and the mixture is heated and allowed to react at over 80 deg.C so as to precipitate an oxide. Then, thus obtained manganese oxide is mixed with active carbon, a conductive member and a water repellent binding agent, and an appropriate amount of water is added to the mixture so as to make a paste. After that, the paste is applied to a current-collecting body made of a nickel net or the like, and the current-collecting body coated with the paste is dried, thereby making a gas- diffuson electrode. When such a gas-diffuson electrode is installed in a battery, the battery indicates an early rising open-circuit voltage, and is provided with an excellent electric-discharge characteristic. In addition, such a gas-diffuson electrode can be favorably used as a positive electrode for a button-type air cell.

Filed: 1987-02-26
Abstract: PURPOSE:To reduce the number of A/D converters so as to simplify a circuit constitution by providing an analogue switch which sequentially selects and outputs one among plural kinds of inputted chrominance signals. CONSTITUTION:The analogue switch 14 sequentially selects only the chrominance signals required among respective chrominance signals of red, green and blue in a video display in a display device, and outputs them in series. Thus, the single A/D converter 16 converts the chrominance signals of one system which are sequentially selected and outputted in series into digital signals and they are sequentially written in a video memory 10. Namely, for the input to the A/D converter 16, the switch 14 selects the chrominance signals corresponding to the colors of respective dots (light emitting elements) and they are sequentially impressed in series. Thus, the A/D converter can be set in one system. Consequently, the number of A/D converters can be reduced and the circuit constitution can be simplified.

Filed: 1987-02-25
Abstract: PURPOSE:To maintain low dispersion over a wide wavelength region and to prevent deterioration in light transmission characteristic by maintaining a difference in the specific refractive index in the central part of a 1st core from a 1st clad. CONSTITUTION:This optical fiber is provided with the core, a 1st clad 2 which exists on the outside thereof and has the refractive index lower than the refractive index of the core, and the 2nd clad 3 which exists further on the outside thereof and has the refractive index lower than the refractive index of the core 11 and the refractive index higher than the refractive index of the clad 2. The core is constituted of the 1st core 11 in the central part and the 2nd core 12 which exists on the outside thereof and has the refractive index lower than the refractive index thereof. The difference in the specific refractive index in the central part of the 1st core 11 from the 1st clad 1 is maintained at >=0.004. The 2nd core 12 formed on the outside of the 1st core, therefore, acts to increase the diameter of a mode field. The self-alignment at the time of optical connection is thereby facilitated while the dispersion is low in the wide wavelength region. The connection loss is thus decreased.

Title: Instrument for measuring mechanical strength of radioactive waste
Inventor: KADO MASUO
IPC: G21F9/36
Filed: 1990-02-22
Abstract: PURPOSE:To measure mechanical strength with a simple structure and high accuracy by providing ultrasonic oscillating means and receiving means, thickness measuring means, propagation time measuring means, propagation speed computing means, and strength computing means. CONSTITUTION:A drum can A is placed on a truck 4 and the thickness of the radioactive waste in the drum can A is first determined. The truck 4 is further moved to a right side and is positioned right under the ultrasonic oscillating means 26. A cover 28 for preventing contamination is opened and a mount 27 is pushed down in a perpendicular direction. Ultrasonic waves are propagated in the waste and are received by the ultrasonic receiving means 31 while the front end of this mount 27 is held in pressurized contact with the surface of the radioactive waste. The propagation time of the ultrasonic waves is measured and the propagation speed is computed by dividing the thickness of the waste by the propagation time. Since the propagation speed of the ultrasonic waves and the compressive strength of the waste have a cross relation, the compressive strength of the waste can be estimated on the basis of this cross relation. The influence of the surface wave generated in the drum can A is eliminated in this way.
