Title: Laser-beam generation apparatus
Inventor: MASUDA HISASHI
IPC: H01S3/094
Filed: 1992-11-26
Abstract: PURPOSE:To restrain a rise in the noise level of a first laser beam and to radiate a second laser beam without being affected by a very small change in the temperature and the current of the second laser by a method wherein the distance between the radiant face and the reflecting face of the first laser beam is set to a distance at which the coherence of the first laser becomes lower than a prescribed level. CONSTITUTION:A laser diode 1, for excitation use, which is arranged at the end of a heat sink 2 generates a laser beam for excitation use and it makes the laser beam incident on a lens 3. The lens 3 condenses the laser beam for excitation use and it makes the laser beam incident on a resonator 4. The resonator 4 integrates a quarter-wave plate 5, a laser medium 6 and a nonlinear optical crystal element 7. It is arranged that the forward and backward optical path length between the radiant face 1a of the laser diode 1 and the reflecting face 5a or 5b of the quarter-wave plate 5 satisfies a relationship by which reflected light is returned to the laser diode 1 in a position where coherence is lowered. Thereby, it is possible to reduce a noise in the low frequency of a laser beam radiated by a standing wave-type resonator.

Title: Refrigerating cycle
Inventor: FUSHIMI KIMIO
IPC: F25B1/00
Filed: 1987-12-17
Abstract: PURPOSE:To conserve power consumption, by cooling down a superconductivity motor for cooling fan using a liquid refrigerant which flows through a refrigerating cycle. CONSTITUTION:A refrigerant compressed by a compressor 21 flows into a condenser 23 under hot temperature and high pressure gageous state. The refrigerant discharges heat with the condenser 23, which is cooled down by the air flow from a condenser cooling fan 29, and is liquefied. This liquefied refrigerant flows divergently into a receiver tank 24 and a liquid line 28 under the guide of an ON/OFF valve 33, which is opened. The liquefied refrigerant which is allowed to flow divergently into this liquid line 28, is partially decompressed by a capilary tube 32, then passes through a cooling cycle 31 for a superconductive fan motor 30 of the condenser cooling fan 29. When passing through the cooling cycle, the refrigerant cools down the motor 30, thereby generating superconductivity phenomena. After that, the power supply to the motor 30 is suspended. However, the superconductive motor 30, which has reached superconductivity status, is allowed to continuously device rotary motion. It is, therefore, possible to conserve electric power after the suspension of power supply to the motor 30.

Title: Play tool with human body detector
Inventor: SUZUKI ISAO
IPC: B43L13/04
Filed: 1992-11-04
Abstract: PURPOSE:To detect a human body accurately without being adversely affected by an environmental change due to an atmospheric temperature and a change over time in equipment by setting anew a reference frequency depending upon whether a change in an oscillation frequency compared to the reference frequency fails within a specified range. CONSTITUTION:It is interpreted (S35) whether a change in an oscillation frequency compared to a reference frequency falls within a specified range, if measurement time is set, by performing measurement in a constant cycle for a specified time (S32). If a change in the oscillation frequency for a given time occurs within the range, a frequency obtained when the measurement ends for a specified time is used anew as a reference frequency (S39). On the contrary, if the change exceeds the range, an oscillation frequency measured when the range is overpassed is used as a reference frequency (S44). At the same time, a play tool is activated by changing an ON/OFF state (S45). Consequently, a frequency measured at a time close to a given state is set as a reference frequency and the approach by a player can be detected without being adversely affected by a climatic change and a change over time in equipment.

Filed: 1992-11-04
Abstract: PURPOSE:To accurately recognize the movable extents of three body axes and deviations among them by making the user of this measuring instrument to make tilting and twisting motions with the upper half of his body while his waist section is fixed. CONSTITUTION:At the time of measuring, for example, the vertical axis of the body of a user, the user positions a slider 35 by moving the slider 35 on a longitudinal circular-arc frame 33 while his waist section is fixed with a waist section fixing means 20. When the user then twists the upper half of his body around the vertical axis, the slider 35 moves to draw a left and right circular arcs on a horizontal circular frame 32. As the slider 35 moves, the shaft lever of the slider 35 collides with a set of marker sleeves 32D on the frame 32 and moves the sleeves 32C in the directions in which the sleeves 32D are separated from each other in accordance with the vertical angle, with the sleeves 32D being stopped after movement. Since the moving amounts of the sleeves 32D are indicated on a vertical scale as an angle, the movable extent of the user with respect to the vertical body axis and the leftward and rightward deviations of the vertical axis can be detected from the angle indicated on the vertical scale.
