Patent JP-H04371179-A (JP)
Title: Slot machine
Inventor: OKADA KAZUO
IPC: A63F5/04
Filed: 1991-06-20
Abstract: PURPOSE:To prevent the damage to a player from becoming excessive without extending the time required for one game or restricting the number of games per unit time. CONSTITUTION:The time required for one game is measured by a one-game timer 35 according to the timing of the control of a start lever 10. A time difference calculating portion 36 finds the difference between the time TG required for one game and a reference time TS from a reference time storage portion 37. The difference (TG-TS) is integrated by an integrating portion 38 and stored in an integrated time storage portion 39. The number of games is counted by a game counter 43 and fed to a re-game control portion 42. The re-game control portion 42 determines whether or not the integrated value of the integrated time storage portion 39 obtained when the number of games reaches a predetermined value is negative and, when the value is negative, produces a re-game signal. A start permission signal is input to a start control portion 22 in response to the re-game signal without any coin put in the slot machine and then a next game can be performed simply by control of the start lever 10.

Title: Inspection method for optical fiber base material and continuous inspection device
Inventor: SAKANO TATSUYA
IPC: G02B6/00
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To enable measuring a core eccentric amount in a short time at close intervals. SOLUTION: A beam from a light source 30 is entered into a base material of an optical fiber through a polarizer 34, and a transmitted beam is taken a picture by a TV camera 38 through an analyzer 36. A transmitted image of the base material identifying a core position is determined by rotating the analyzer 36. A core eccentric amount for the base material is determined by image-processing this image, and also, a core eccentric amount of the optical fiber after spinning can be estimated. A measurement result equivalent to a result by a conventional preform analyzer is obtained by this method, and the measurement can be done in a very short time at fine intervals.

IPC: G06K7/10
Filed: 1985-08-10
Abstract: PURPOSE:To reduce an erroneous reading rate by detecting a waveform breakage generated when bar code signals are binary coded, and judging the validity of a bar code information. CONSTITUTION:Bar width information is stored successively in an FIFO memory 21. When a waveform breakage is detected, a waveform breakage flag is stored with a bar width information. A demodulating circuit 22 starts the demodulation of segments while detecting a guard bar or center bar from the memory 21, and when the waveform breakage flag is detected, invalidates the data of the segments, and stores a data from which the flag is not detected in a memory 7. In this case a bar code label is scanned plural times and above-mentioned operation is repeated and effective data are stored in the memory 7. After the completion of several times of scanning, a series of data are constituted from effective data stored in the memory 7.

IPC: H01S3/034
Filed: 1989-07-11
Abstract: PURPOSE:To eliminate the need for providing an independent aperture in addition to a laser window and simplify a device by providing an opening at a valve for intercepting laser gas so that its opening demarcates the cross sectional form of a laser beam in a state that a chamber is in direct communication with the laser window. CONSTITUTION:As a valve 4 for intercepting laser gas is provided between a chamber 1 which makes laser gas airtight and a laser window 5 which is provided on a laser light path, sealing of laser gas in the chamber 1 is maintained by closing the valve 4, for example, when the inside of the laser window 5 is cleaned. In this way, working is simplified and its simplification reduces the loss of laser gas. Further, the projection form of the laser beam direction in an opening of the valve 4 has a prescribed aperture form in a state that the valve is open and demarcates a sectional form of an outputted laser beam. As the opening itself of the valve 4, in this way, has the aperture form, it is unnecessary for its valve to prepare the aperture separately so as to demarcate the sectional form of the outputted laser beam.

SOLUTION: The case member 2 of the hollow fiber membrane module 1 is formed of the non-woven fabric made into the cylindrical shape. As a result, the fluid to be filtered flows smoothly into the hollow fiber membrane module 1 from the entire part of the non-woven fabric cylinder 2 and, therefore, the inflow area increases without the pressure drop and a uniform pressure is applied on the fiber bundles 5 of the hollow fiber membranes to ensure efficient filtration. Even if a filter material coexists in the fluid to be filtered, the non- woven fabric cylinder 2 functions as a primary filter and, therefore, the deposition and clogging of the hollow fiber membranes 4 themselves are prevented.  Since the inside surface of the non-woven fabric cylinder 2 have no large openings, the flawing and breaking of the hollow fiber membranes 4 at the time of packing the fiber bundles 5 of the hollow fiber membranes are prevented and the assembly quality is improved.

Filed: 1983-09-28
Abstract: PURPOSE:To enable the prevention of malfunction due to the variation in various kinds of conditions by a method wherein the time constant of a transistor formed by adjacent three layers in a thyristor is so set as to come into the range of a specific condition. CONSTITUTION:The transistor TR21 is provided between the gate G and the cathode K of the thyristor, and a TR30 is connected between the base of the TR 21 and the n-base 12 of the thyristor. When the time constant of the TR20 formed of the p1n1p2 layer of the thyristor is tau1, and the time constant of the TR30 is tau2, the value of tau2/tau1 is so set as to be in the range of 0.1-0.5. The selection of the value of the time constant ratio tau2/tau1 in this range enables the formation of a semiconductor switch execellent in noise resistance. With the value of tau2/tau1 of 0.1 or less, a practical element can not be formed because of low dv/dt strength. With the value of 0.5 or more, ignition does not occur even when ignition pulses are impressed. The selection of the value in the range of 0.1-0.5 is enabled by putting each pattern of the p1n1p2 TR20 and TR30 of the thyristor in congruency or similarity.

Abstract: PURPOSE:To improve the reliability of the nuclear reactor by utilizing a magnetic fluid pump which has no mechanical movable part as a neutron absorber injection pump. CONSTITUTION:When the safety device is actuated, an explosion valve 18 explodes to open and magnetic fluid which is pressurized with the necessary gas in a storage tank 16 and contains atoms large in heat neutron absorption sectional area is passed through a magnetic fluid pump 17 and the explosion valve 18 in the open state and injected into the reactor 13 to operate as a neutron absorber, thereby decreasing the output of the reactor 13. The steam in the reactor 13, on the other hand, is admitted to the pump 17 and applied to a magnetic field applied to the fluid 15 running through the pump 17 to generate a temperature difference. Consequently, the fluid 15 is raised in pressure. Therefore, the fluid 15 as the neutron absorber in the storage tank 16 is injected speedily into the reactor 13 by a large amount with the necessary gas pressure in the storage tank 16 and the discharging force of the pump 17, so atoms in the fluid 15 absorb neutrons in the reactor 13 to stop the operation of the reactor 13. Thus, the pump 17 has no mechanical movable part, so the reliability is improved correspondingly.
