Title: Stress meter
Inventor: SASAKI NOBUHIRO
IPC: G01L1/08
Filed: 1982-09-28
Abstract: PURPOSE:To measure stress with a simple structure with extremely high accuracy, by combining a highly sensitive balance and a stress generator consisting of a displacement detector, permanent magnet, and coils and automatically balancing them. CONSTITUTION:A shaft 3, to which a bar magnet 1 and the core 2 of a differential transformer are connected, is hung from one end of a balance consisting of a strut 4, arm 5, and pivot 6 and a weight 7, whose distance from the fulcrum of the balance can be adjusted manually, is fitted to the other end of the balance, so that the balance is balanced. Then a stress generating coil 8 and the coil 10 of the differential transformer are arranged around the shaft 3. Moreover, a balance compensating coil 9 is wound around the outer surface of the coil 8 and permanent magnets 11 and 12 are installed so that the shaft 3 is not brought into contact with the inner surface of the coils. If, when force F is applied, the stress of the same magnitude as the force F and in the opposite direction is generated by flowing an electric current to the coil 8, the shaft 3 is not displaced and the electric current is accurately proportional to the force F as a result of the generation of the stress, the value of the electric current as the time is accurately measured.

Title: Deciding device for key input
Inventor: NISHIGUCHI YUKIHIRO
IPC: G06F3/02
Filed: 1986-07-18
Abstract: PURPOSE:To prevent chattering of keys as well as malfunctions due to the double-push actions of keys without using a double-push preventing device nor a chattering preventing device, by adding plural gate circuits to an arithmetic processing circuit. CONSTITUTION:When an instruction is read out of a ROM by means of a key, a digit timing signal is supplied to an AND gate 30 via an output terminal K1 with push of a key 51 and then updated to an addition/subtraction device 23 via an OR gate 25. The device 23 adds '0' to the input signal and outputs '1' and logic '1' is written to a shift register 21 via an AND gate 27 and an OR gate 24. Then subtraction is carried out by the device 23 between the signal obtained with push of the next key and the signal stored in the register 21. The result of this subtraction if equal to '0' (coincidence secured between both inputs) is supplied to an FF 33 and a ROM address is designated. Therefor, it is possible to decide that different keys are pushed with other results of subtraction excepting for 0. As a result, the chattering of keys and the malfunctions due to double-push of keys can be avoided without using a double- push preventing device, etc.

Title: Headlamp washer
Inventor: KUSAYA MASAHIRO
IPC: B05B1/30
Filed: 1990-06-29
Abstract: PURPOSE:To surely prevent a washing liquid from leaking by providing a spring for pressing a piston into a cylinder, a shutoff valve to be incorporated into the piston and used for blocking a normal flow passage, and a spring having a spring force greater than that of the former spring and used to press the shutoff valve in the direction in which the valve is closed. CONSTITUTION:A washing liquid 1 is forcibly fed into a cylinder 3 and then fluid pressure P acting on a piston 2 is gradually raised and when a force multiplied by the pressure P and the effective area of a third piston 33 excels the spring force of a spring 14 the piston 2 is pushed up against the spring 14. When the piston 2 is raised and the spring bearing portion 40 of a second piston 32 comes into contact with the stopper 56 of a cylinder cover 51 and is stopped, the fluid pressure P within the cylinder 3 starts to rise again and when exceeding the spring force of a spring 20 pushes up a shutoff valve 37 against the spring 20 and separates the valve 37 from a valve seat 45. Since the fluid pressure P acts on the shutoff valve 37 in the direction of the axis of the valve 37, the shutoff valve 37 is stably seated on the valve seat 45 and prevents the washing liquid from leaking during closing.

Title: Refrigeration circuit
Inventor: TAGASHIRA HIDEAKI
IPC: F25B41/00
Filed: 1987-07-07
Abstract: PURPOSE: To eliminate pulsation sound generated from a compressor and hereby reduce noise by a method wherein cross sectional areas of discharge pipings each connecting two compressors and a condenser are made same, and differences among the discharge pipings are set to be an odd time of a half wavelength of pressure pulsation of refrigerant gas discharged from the compressor and are cancelled out at a joining part. CONSTITUTION: Pipings 5a, 5b are connected to respective compressors 1a, 1b, and internal cross sections thereof are made equal to each other. When lengths of the pipings 5a, 5b are assumed l1 , l2 , and a difference Δl=|l1 -l2 | is assumed 1/2 the wavelength of a pulsation, specific pressure pulsation of refrigerant gas discharged from the compressors 1a, 1b passes through the discharge pipings 5a, 5b, and join at a branch pipe 9a. Thereupon, since the difference among the lengths of the pipings is different by a fraction of the half wavelength of the pulsation, positive pressure and negative pressure are just overlapped and cancelled out, and passing refrigerant gases are also a same amount, so that a cancelled amount is also made equal, and hence attenuation effect of the pressure pulsation is made maximum.  Thus, even when the refrigerant enters the piping 5 and the condenser 2, the pressure pulsation is eliminated, and hence vibration and noise are reduced.

Title: Magnetic bearing
Inventor: MURAKAMI TSUTOMU
IPC: F16C32/04
Filed: 1980-12-02
Abstract: PURPOSE: To obtain a simple structured magnetic bearing of strong axial rigidity by means of three respective opening magnetic paths between a rotor and a division of a stator, one electromagnetic coil and one permanent magnet.  
     CONSTITUTION: A rotor 1 consists of one yoke 3 comprising a magnetic substance. A stator 2 is divided at least into three pieces and interconnected by a non-magnetic connector 7. Each division 2aW2d of this stator 1 consists of cross- sectional rectangular yokes 8aW8d and cross-sectional angular frame electromagnetic yokes 9aW9d with opened upside. Permanent magnets 10aW10d are  placed between the yokes 8 and 9 and electromagnetic coils 11aW11d are placed  in a part of the electromagnetic yoke 9 respectively. Three opening magnetic  paths 13, 14 and 15 are formed between the rotor 1 and the stator 2. Since the  first opening magnetic path 13 is an exclusive path for magnetic flux ϕ1 of a  magnet 10 and magnetic flux density need not be controlled by magnetic flux  ϕ2 from the electromagnetic coil 11, magnetic flux can be fully elevated.

Filed: 1989-06-30
Abstract: PURPOSE:To realize compatibility of sound image location and low frequency range by forming coaxial composite speaker unit with a tweeter and a woofer and arranging the even number of super woofer in positions symmetric each other on a vertical line. CONSTITUTION:A coaxial composite loudspeaker unit 1 equipped with a diaphragm 2 for low range and a diaphragm 3 for high range is fitted to a cabinet 4. A super woofer unit 5 is arranged one by one respectively in the positions separated from the center of the vertical line at an equal distance. Then, pseudo coaxial constitution is obtained.
