Title: Fiber optical rotary sensor
Inventor: JIYOOJI EI PABURASU
IPC: G01C19/64
Filed: 1986-02-26
Abstract: @ A gyroscope system includes a coherent light source that supplies counterpropagating waves to a sensing loop through a pair of directional couplers. The polarizations of the waves are controlled so that they traverse identical paths before recombining in one of the couplers to form an interference pattern. Rotation of the sensing loop, a phase modulator and a frequency shifter cause phase changes in the counter propagating waves. A detector monitors the interference pattern of the combined waves and provides a signal to the coherent demodulator that controls the phase modulator. The output of the coherent demodulator is input to a servo loop circuit that drives a voltage controlled oscillator. The output of the voltage controlled oscillator is an oscillatory signal having a frequency equal to the shift in frequency that the counter propagating waves experience in traversing the frequency shifter. The feedback circuitry adjusts the frequency shift to null the phase difference between the counterpropagating waves. The frequency shift is linearly related to the frequency of the signal output from the voltage controlled oscillator. Each cycle of the output of the voltage controlled oscillator corresponds to a fixed angular increment of displacement of the sensing loop. The rotation rate of the sensing loop is a function of the frequency shift and transit time of the waves through the sensing loop. The gyroscope system determines rotation rates and angular displacements over a wide dynamic range by measuring the frequency and zero crossings of the oscillatory output of the voltage controlled oscillator.

Title: Device for measuring remaining fuel quantity for vehicle
Inventor: KOBAYASHI HIROSHI
IPC: G01F23/00
Filed: 1982-03-19
Abstract: PURPOSE:To perform the measurement of the remaining fuel quantity accurately, by measuring a plurality of periods of transmitted signals which have the periods proportional to a liquid level, and performing a specified averaging operation. CONSTITUTION:The pulse signals are proportional to the liquid level which is varied by the variation of the volume in a fuel tank indicated by a remaining fuel meter 1,  and the signals are outputted from a detecting circuit 2. The pulse signals for N periods corresponding to a running time and a stopping time are outputted to a pulse period measuring part 31 from a running judging part 30 based on the signal from a running sensor 4. At the same time the address corresponding to the N is specified in a  signal memory part 33. A period comparing part 33 compares the magnitude of the  period detected by the measuring part 31 and the results are stored in the memory part 33 in the sequence starting from the shorter period. An averaging part 34 computes an  averaged period T of intermediate data which are obtained by subtracting (n) pieces at  both sides from the stored data of N pieces in the order of magnitude. Remaining quantity operating part 35 computes the remaining fuel quantity based on the T and imparts  the result to an indicator 5. Therefore the highly accurate remaining fuel quantity is  measured.

Title: Preventing method of generation of needle crystal from tin plated product
Inventor: USUI IKUO
IPC: C23C2/08
Filed: 1979-04-11
Abstract: PURPOSE:To prevent whiskers from generating from tin plating by heating tin- plated products at a temperature higher than m.p. of tin under non-oxidizing atmosphere. CONSTITUTION:Generation of whiskers (needle crystals) in tin plating is ued to stress and strain in tin-plating, so no whisker occurs in molten tin plated products. Therefore, to reduce plating stress and strain, plated tin is remelted. That is, tin- plate products are heated at a temperature higher than m.p. of tin, under non- oxidizing atmosphere so that plated tin is melted. The so processed products are free from whisker generation which causes failures to the products, during long periods of shelf life.

Filed: 1994-02-17
Abstract: PURPOSE:To improve boring accuracy and extend the service life of each bit by providing an expandable bit in addition to a forward end bit and an intermediate bit, and boring a hole using three types of bits having a different diameter. CONSTITUTION:Torque and an impact force are applied from the base end of a boring rod 11 inserted in a tube body 20, and the supply of the air and water is started through a shaft tunnel 15. Then, when the impact force is transmitted to an intermediate rod 30 integrally connected to the boring rod 11, a slide cylinder 40 retreats until the collision thereof with an annular collar 32. With the progress of the retreat of the cylinder 40, an expandable bit 14 slides toward the shallow side of a shaft groove 34, and projects to the extent of the maximum diameter thereof. In this state, the torque and the impact force acts on a forward end bit 12, an intermediate bit 13 and the expandable bit 14, thereby boring a hole. By using three types of the bits 12 to 14 as mentioned, a boring load acting thereon is alleviated. Thus, not only linear motion function is improved, but also the service life of the bits 12 to 14 is extended.

Title: Water jump course
Inventor: BAANAADO HIIJI
IPC: A63G3/00
Filed: 1987-02-27
Abstract: The water jump way comprises a jump track (8), a boat (20) and a water basin. The boat (20) has front and rear wheels (21, 22) with a different track width. In the jump-off region (28) of the track (8), the running surface (25) for the rear wheels (22) is curved upwards to a lesser extent than the running surface (24) for the front wheels (21). It is thus achieved that, after the front wheels (21) have been lifted off from the end (27) of the track, the twist of the boat (20) is only slightly reduced despite the long wheel base and different loading of the boat (20) and consequently the landing angle of the boat (20) in the basin can be kept in a favourable range. This allows a circulation of the boats and a crew of more than one person.

Abstract: PURPOSE:To facilitate setting of a rated current value corresponding to a change in the state of a load and to protect the load excellently by inputting a reset signal and by setting a rated current on the basis of a load current at the present time point. CONSTITUTION:A current sensor 1 delivers an output current being proportional to a load current I on a line 7 and it comprises a current transformer 8, a full-wave rectification circuit 9 and an input circuit 10 executing digital conversion. A control circuit 3 writes the amplitude of the output current of the current sensor 1 in a storage element 2 synchronously with a reset signal and sets a rated current on the basis of the amplitude of the output current. It judges the presence or absence of abnormality of the output current of the current sensor 1 in comparison with an abnormality judgment reference value set on the basis of the rated current, and outputs the result. Based on the judgment output, an output circuit 4 delivers a tripping signal. According to the tripping signal, a tripping device 5 opens a main contact part 6. Accordingly, an optimum tated current value is made to be used by outputting the reset signal when a motor is put in a steady state of operation, for instance.
