Abstract: PURPOSE: To enable plural golfers to decide the distance and the direction up to a selected golf course point with high accuracy and large realizability, by using the principle of a spread-spectrum ranging signal and a hyperbolic location algorithm for measuring a golf course and the direction. CONSTITUTION: Respective hand-held receivers 7 and 10 have a PN code epoch recovering processor 12 to receive a PN modulated carrier liquid of transmitters 1 to 6, and a time difference measuring processor 14 decides a time difference between a local code timing epoch and a received tracking code epoch of a transmuted signal. A distance and direction measuring processor 16 decides a distance between a golfer and a specific target on the basis of this information. A programmable memory 18 stores coordinates of a reference transmitter, a pin position of a golf course and the other reference point, and decides a distance and the direction to be displayed by using this information together with information gathered in the time difference measuring processor 14.

Abstract: PURPOSE:To simplify the manufacture and to improve the productivity by placing 1st and 2nd capacitors side by side on a board and connecting electrodes of the 1st and 2nd capacitors formed on the upper face of the substrate to electrodes of the 1st and 2nd capacitors formed on the lower face of the substrate respectively by an electric conductor line. CONSTITUTION:Electrodes 8a, 8b' of 1st and 2nd capacitors C1, C2 and electrodes 8a', 8b of 2nd and 1st capacitor C2 are formed to upper and lower faces of a ferrodielectric substrate 2 with inverting the top and bottom relation, then when a voltage is applied between the electrodes of the 1st capacitor and the electrodes of the 2nd capacitor, the 1st capacitor C1 and the 2nd capacitor C2 are excited in an opposite mode without fail. Thus, the excitation of the 1st and 2nd capacitors C1, C2 are cancelled and no excitation appears as a whole of the capacitor C. Moreover, when the ferrodielectric substrate 2 is subjected to shock or the like, a piezoelectric noise voltage nearly equal to each other is generated in the 1st and 2nd capacitors C1, C2. In this case, the piezoelectric noise voltage caused in the 1st capacitor C1 is opposite in phase to the piezoelectric noise voltage caused in the 2nd capacitor C2.

Title: Cradle position control method and pedestal for subject
Inventor: TSUJII YOSHIAKI
IPC: A61B5/055
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To improve exactness in position control by moving a cradle away from a target position and returning it to the target position later when moving the cradle oppositely to the last moving direction. SOLUTION: A control part 50 judges whether a cradle 24 is located at its initial position or not corresponding to the signal of a photosensor 41 and returns it to the initial position. When out-drive is performed, for example, an out-drive flag is raised. Next, when an examination position is inputted, the moving direction is judged by the out-drive flag. Then, in the case of the moving direction opposite to the last time, namely, in the case of in-drive, the cradle 24 is in-driven further away from the target position, out-driven and returned to the target position later. Inversely, in the case of the case out-drive as the last time, since there is no play, the cradle is out-driven and directly moved to the target position. Thus, the play in the case of moving the cradle oppositely to the last time is canceled and position accuracy can be made exact.

Abstract: PURPOSE:To realize a low power consumption circuit with a minimum circuit element number by using an input transistor (TR) of a hysteresis comparator to a temperature detection section. CONSTITUTION:An output voltage of a reference voltage circuit 7 of the band gap system is divided by resistors R4 and R5 via an emitter follower TRQ4 and fed to an input TRQ5 of a current source CC2 load of the hysteresis comparator. Further, the output of the comparator is fed to an output TRQ8 through a circuit comprising a current source CC3, a TRQ6 and a common emitter resistor via a circuit comprising an emitter follower TRQ7 and resistors R7, R8. When the TRQ5 is turned off at a low temperature, the relation of VB>VB5(ON) is established (where; VB is base voltage and VB5(ON) is a base voltage to turn on the Q5 from the off-state), the Q5 is turned on to attain thermal protection state. When the temperature decreases and the relation of VB5<VB5(OFF) is established, the Q5 is turned off to release the thermal protection.

Title: Shaft seal device for turbo charger
Inventor: YAGI YOICHI
IPC: F02B39/00
Filed: 1988-08-03
Abstract: PURPOSE:To suppress consumption of oil, by communicating a space between two ring seals interposed on a rotary shaft to the upper course from a throttle valve, and setting the cross section of a communicating passage in response to the minimum sealing performance of the ring seals. CONSTITUTION:A space between two ring seals 12, 13 interposed on a rotary shaft 12 is communicated to the upper course from a throttle valve 16 via a passage 15. The cross section of the passage 15 is set by limiting its lowermost value in response to a leakage of the ring seal 13 on an impeller 3 side so that a differential pressure between a space between both ring seals 12, 13 and a bearing housing 5 does not exceed the minimum pressure sealing performance of the ring seals. Thus the oil is prevented from being sucked toward the impeller 3 side so that consumption of the oil can be suppressed.

Title: Superconductive magnetic shielding type cathode-ray tube
Inventor: USHIO TETSUYA
IPC: H01J29/88
Filed: 1987-08-03
Abstract: PURPOSE:To obtain a clear picture in a light weight and at a low cost even at a place where an external magnetic field is strong by preventing the invasion of a magnetic flux into an interior by installing a superconductive magnetism shielding on the surroundings of an electron beam path from an electron gun to a display surface. CONSTITUTION:A magnetism shielding body made of a superconductor is arranged on the surroundings of an electron beam path 4 from an electron gun 1 to a display surface 5 and a superconductive magnetism shielding 2 is executed. This magnetism shielding 2 is formed by the application film of the superconductor applied to the surroundings of a cathode-ray tube. When it is thus constituted, since the super conductor is simultaneously a perfect anti-magnetic substance, the magnetic flux is not allowed to invade into an interior. For this reason, the magnetic flux from an exterior can not pass through the magnetism shielding 2. Accordingly, a perfect magnetism shielding can be achieved. Even when the display surface 5 of its own is not provided with the shielding, since the circumference is surrounded by the superconductor and the magnetic flux cannot pass the surface to invade deep into the interior, a similar effect is attained. Further, a thin and lattice-like shielding is allowable and consequently a light weight and a low cost can be attained.
