IPC: H01S5/042
Filed: 1987-10-08
Abstract: PURPOSE:To simplify a process by a method wherein a current path layer is grown on a high-resistance current-constriction layer and a groove by a liquid epitaxial growth method and a laser oscillation layer composed of a GaAlInP-based material is grown on it by a metal organic vapor growth method. CONSTITUTION:A current-constriction layer 2 which becomes substantially highly resistant is grown on one main face of a substrate 1 of one conductivity type; a groove 3 whose depth ranges from the surface of the current-constriction layer 2 to the substrate 1 is formed. Then, a current path layer 4 whose conductivity type is identical to that of the substrate 1 and whose surface is flat is grown on the current-constriction layer 2 and the groove 3 by a liquid epitaxial growth method; after that, a laser oscillation layer 8 composed of a GaAlInP- based material is grown on the current path layer 4 by a metal organic vapor growth method. By this setup, an etching process is finished at one time, and a process can be simplified.

IPC: G11B20/14
Filed: 1991-09-06
Abstract: PURPOSE:To suppress an erroneous detection caused by a noise adding a level reproduced with a recording medium, and a signal level after a prescribed time therefrom, and comparing its level with a prescribed reference level. CONSTITUTION:The device is provided with a latch circuit 32 for latching a level at a prescribed timing of a signal reproduced from a recording medium such as a magneto-optical disk, etc., and a latch circuit 31 for latching a level of a signal at a timing being later by a prescribed time than the level.

Title: Pyroelectric detector
Inventor: HOSHINO YASUSHI
IPC: G01J5/02
Filed: 1989-09-29
Abstract: PURPOSE:To decide the intruding direction and the moving direction of a person by forming the light receiving electrode of a pyroelectric element in a ring shaped so that a ring-shaped sense zone and a non-sense zone in its center are formed. CONSTITUTION:The electrodes 14 and 15 of the pyroelectric element 13 are formed in the ring shape and the distance between the light receiving electrode 14 and a lens 18 is adjusted so that the sense zone 17 covers all entrance exits 11a - 11c of a room 12.

An output when the person crosses the sense zone 17 from outside to inside and an output when the person crosses the sense zone from inside to outside are 180 deg. out of phase with each other. Consequently, the intruding direction and moving direction of the person can be decided.

Title: 2-step type identical centrifugal force generator
Inventor: KIHARA KOKI
IPC: G01M99/00
Filed: 1992-09-24
Abstract: PURPOSE:To provide a compact 2-step type identical centrifugal force generator by preparing a means for adjusting the anglular velocity in a manner to make the centrifugal forces to identical masses equal when a rotatable inner cage chamber and a rotatable outer cage chamber are rotated around the rotary axis and outside the inner cage chamber, respectively. CONSTITUTION:An inner cage chamber 1 is rotated through the rotation of a rotary axis 1a and the rotation is transmitted to an outer cage chamber 2 by means of a power transmitting disc 3. When it is assumed that the radiuses of inner cage gear 4, transmitting inner gear 5, transmitting outer gear 6, and outer cage gear 7 are h1, h2, h3, and h4 respectively, and that the angular velocities of the chambers 1 and 2 are w and W respectively, their relation can be represented as follows: W/w=(h1/ h2)X(h3/h4). The radiuses of position for holding specimens and the rotating angular velocities are expressed as r and R for the chamber 1 and w and W for the chamber 2. In order to make the centrifugal forces applied to the masses (m) in both chamber to be equal, the formula, mrw<2>=mRW<2>, that is, W<2>/w<2>=r/R shall be satisfied. Since W/w=(h1.h3)/(h2.h4) the formula, (r/R)<1/2> =(h1.h3)/(h2.h4) can be obtained. Therefore, the values of h1 to h4 for r and R can be determined properly, so that the centrifugal forces per equal masses in the chambers 1 and 2 may be made equal to each other.

Title: Motor
Inventor: LAU JAMES CHING SIK
IPC: H02K5/167
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a silent motor by reducing the rattling noises of a bearing. SOLUTION: A permanent magnet DC motor 10 has a casing 11 for storing a permanent magnet of a stator to from a flux return path. The wall thickness of the casing 11 is so formed, that the casing 11 is saturated magnetically. A magnetic flux ring 30 is put around the permanent magnet and embedded in the casing 11. The magnetic flux ring 30 has a gap 35 between opposite edges thereof. Since the gap 35 of the magnetic flux ring 35 is made to be aligned with a space between the permanent magnets, the flux return path comes mainly over only the casing 11 on one side, while it comes over both the casing 11 and the magnetic flux ring 30 on the other side. Then, the center of the magnetic field can be shifted to the side of the magnetic flux ring 30.

Filed: 1987-10-12
Abstract: PURPOSE: To form a blue Pachinbko ball (used in Japanese pinball game) and to perform discriminate from other shops by the Pachinko ball by using vanadium, far instance, as metal for color development. CONSTITUTION: Zirconia is used as a base material so as to obtain this Pachinko ball capable of obtaining an almost similar use feeling even as the substitute for the Pachinko ball made of iron and being easily colored without discoloration. The specify gravity of the zirconia is 6.5-6.8 and is close to the specific gravity 7.86 of the iron and it is optimal as the substitute for the iron. Then, in order to color the Pachinko ball to a desired color, the small amount of the metal for the color development is added before sintering. The density of the color is freely changed by the adding amount of the metal for the color development and the discrimination from other balls is easily performed by changing the density of the color even when it is the same color. Thus, the Pachinko ball of high durability almost without wear by use is attained.  Also, the discrimination from the balls of the other shops is extremely easily performed.

The liquid refrigerant enters a cooling expansion valve 15, an indoor area is cooled by the indoor devices 11 and 12 and this liquid refrigerant is sucked into the compressor 1. When the surrounding air temperature is low and a high pressure is decreased even if the outdoor fan 7 is stopped, the two-way valve 23 is closed, the two-way valve 26 is opened and the electromagnetic valve 34 is changed over to a closed state. The discharged gas from the compressor 1 is not flowed to the outdoor heat exchanger 3, but flows only in the indoor device 13 so as to prevent a reduction in a heating capability.

Title: Power source controller of electronic apparatus having hard disk function
Inventor: KURIKI HIROSHI
IPC: G06F11/00
Filed: 1996-08-21
Abstract: PROBLEM TO BE SOLVED: To avert the disk breakage which occurs when a power source switch is turned off during working of a hard disk, by providing the controller with a circuit for controlling the on and off of a power source by receiving inputted signal indicating the working state of the hard disk. SOLUTION: The output of the output terminal 7 of a control CPU 5 controlling the hard disk 3 attains 5V if the hard disk is under working. When the output of the terminal 7 is 5V, the power source switch 9 is turned on by the control circuit 8 and, therefore, even if the power source switch 2 is turned off, the cut-off of the power source is prevented by the on of the switch 9. According, the damage of the hard disk 3 does not arise. Since the terminal attains 0V when the operation of the disk 3 ends, the switch 9 is turned off by the circuit 8 and the power source is cut off for the first time at this time. Once the power source is cut off, the circuit 8 does not operate until the power source turns on next and, therefore, the switch 9 is held at off. The turning on of the power source is thus executed always by turning on the switch 2.
