Title: Underwater communication system
Inventor: YAMADA WASAKU
IPC: H04B11/00
Filed: 1986-11-28
Abstract: PURPOSE:To facilitate a wireless communication between divers each other or between a diver and a person on a ship by outputting a voice corresponding to a switch input from a voice synthesizing circuit previously storing the voice, transmitting the signal as an ultrasonic signal after analog modulation and demodulating so as to output a sound signal in a reception side. CONSTITUTION:By operating a switch, a corresponding code is outputted from an encoder circuit 2 to a voice synthesizing output circuit 3. The speech synthesizing output circuit 3 reads out corresponding voice data which is previously recorded from a ROM and D/A converts it to transmit to a modulation circuit 4 as an analog sound output. The signal is modulated, for example in terms of AM modulation, in the modulation circuit 4 and amplified in a power amplifier 5, so that the ultrasonic signal is radiated from an ultrasonic transducer 7 into the water through a circulator 6 as analog sound data. The reception part inputs the signal in a pre-amplifier part 8 through the circulator 6 and amplifies it. After the signal is detected in a demodulation circuit 9, it is amplified in the power amplifier 10, so that a diver can hear the signal by using a bone conduction earphone 11.

Title: Fan coupling for car
Inventor: WATANABE TAKEAKI
IPC: F16D35/02
Filed: 1985-12-20
Abstract: PURPOSE:To enable the device to work with its max. cooling capacity regardless of engine coolant temp. in the radiator, if such is required, by impressing voltage on a bimetal for controlling operation of a valve, which is to open and close a hole provided at a storage for a viscous fluid to be used in a fan coupling, and by heating the bimetal directly. CONSTITUTION:A slip ring 20 is mounted on a bimetal 14, which actuates a slide valve 7, and connection is made to the power 19. In linkage with an airconditioner switch 18, power is directly supplied to this bimetal 14 from the power supply 19. The bimetal 14 will thus run temperature and expand to result in rotation of the slide valve 7. Thereby an inlet hole 12 is opened to allow influx of viscous fluid 4 into a working chamber 16, and the fluid sent to a labyrinth part 11 intrudes into gaps formed by ridges 9, 10 of the driving part 2 and driven part 3. Thus rotation of the driving part 2 is transmitted to the driven part through the viscous fluid 4, and a cooling fan is rotated. The device can thus work with its max. performance regardless of the engine coolant temp. within the radiator, if desired.

IPC: A61L2/26
Filed: 1988-11-15
Abstract: PURPOSE:To safely open and close air holes timely by providing a spring made of a shape memory alloy and a stopper for checking blocking of the air hole. CONSTITUTION:A coil spring 10 made of a shape memory alloy and a balance spring 11 against the above spring are formed and fitted between a hook 12 and a slide panel 6. A through hole 3a is bored in a cover 3, and the forward end of a stopper 13 made of a shape memory alloy faces on the position for stopping sliding of the slide panel 6. The stopper 13 is manually operated to keep the air holes in the release state before a receptacle is put in a stem sterilizer, and before steam is poured, at the time of vacuum suction at an ordinary temperature, the air holes are opened. With a temperature rise due to stem sterilization, the spring 10 is loosened to keep the release state of air holes 4, 7, and the stopper 13 is returned to such a form not to check blocking. When steam sterilization operation is completed and the temperature drops, the air holes 4, 7 are blocked by the action of the balance spring 11. Thus, the air holes can be automatically released and blocked timely.

Title: High-pressure fuel pump
Inventor: HASHIDA MINORU
IPC: F04B1/12
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To carry out adequate lubrication of the sliding portions of the driving mechanism without using bellows by providing material to seal the clearance between the plunger and the cylinder and the swash plate side from a passage opened to the body and the cylinder. SOLUTION: Sliding friction of a load supporting part is reduced by the relative rotational speed and lubrication with oil. For oil lubrication, a mechanism for retaining oil in a swash plate chamber 44 formed between the body and a cylinder block 16 is required. To fill this requirement, a shaft seal 38 is provided at a slipper 13 side of an intake slot 30 of a plunger 14, creating a seal between the fuel and oil during reciprocating motion of the plunger 14. This seals the clearance between the plunger 14 and a cylinder bore 17, and the shaft seal 38 becomes the boundary between the fuel and the oil. In this mechanism, the low pressure intake pressure at the intake slot 30 is always acting on the shaft seal 38: the pressure does not become large like the internal pressure in a pump chamber 42, and a constant pressure acts on the shaft seal 38.  This improves both the sealing properties and the reliability of the shaft seal 38.

Abstract: PURPOSE:To measure the ellipticity or the like by moving a laser beam or a metallic thin wire very slightly in a direction perpendicular to the irradiating direction of the laser beam, detecting the change of the temperature of the metallic thin wire and measuring the intensity distribution of the laser beam. CONSTITUTION:A metallic thin wire 15 is mounted to a precise positioning apparatus 16 in a manner to be movable very slightly in a cross sectional direction (B direction) perpendicular to the irradiating direction (A direction) of the laser beam 1. When a laser beam 1 is irradiated to the thin wire 15, the temperature of the thin wire 15 is raised in proportion to the receiving amount of the beam 1. Therefore, when the thin wire 15 is very slightly moved to the beam 1 by the apparatus 16 and the temperature rise at each moving point is measured, the intensity distribution of the beam 1 in a lateral mode is obtained from the relation thereof with the thin wire 15. The ellipticity and position of a focus can be obtained from the intensity distribution.

Title: Receiving device for spread spectrum communication
Inventor: MOCHIZUKI NORIHIRO
IPC: H04B1/709
Filed: 1988-11-14
Abstract: PURPOSE:To demodulate a received signal from spread spectrum communication at high speed by providing a convolving means to take correlation between the received signal and a reference code outputted from a code generating means and a demodulating means. CONSTITUTION:The convolver 2 inputs the received signal 1 and a reference signal 3 that a carrier wave generated by an oscillator 9 is phase-modulated by a modulator 8, and when both signals coincide with each other, it generates sharp peak output. Then, a threshold is set properly fixedly or variably so that only the peak output outputted from the convolver 2 exceeds the threshold when the output of a detector 5 and the threshold set beforehand are compared by a threshold detection circuit 6. Accordingly, only when the signal 1 and the signal 3 coincide, a pulse is outputted from the circuit 6, and by inputting the pulse to a code generator 7, the timing of the reference diffused code to be generated from the generator 7 is adjusted, and synchronization between the signal 1 and the signal 3 is made. Thus, the demodulation of the received signal can be started earlier through a gate pulse generator 10, a gate circuit 11 and the demodulation circuit 16, and the received signal can be demodulated at high speed.
