Title: Helium gas precooling unit
Inventor: HORI MASAYOSHI
IPC: F28D9/00
Filed: 1985-09-24
Abstract: PURPOSE:To form a wide nuclear boiling heat transfer region under fluidized state having a high heat transfer function by constituting the precooling unit of a plate-fin type heat exchange portion having an outlet for cooled helium, and a downcomer portion disposed so as to place the boiling side outlet portion of the heat exchange portion in communication with the inlet portion thereof. CONSTITUTION:When a supercritical pressure helium gas is caused to flow from a primary side inlet 8 to the primary side 4 of a heat exchange portion 2, and a low pressure liquid helium is supplied into a downcomer portion 3 through a secondary side inlet 10, liquid helium flows from a secondary side inlet portion 7 to a secondary side 5 and is guided to a secondary side outlet 6. Upon this occasion, a heat exchange is carried out between the primary side 4 and the secondary side 5, and the supercritical pressure helium gas which has passed the primary side 4, is cooled end discharged through the primary side outlet 9. Since the liquid helium flows on the secondary side 5 is boiled and partly converted into a vapor, the liquid helium flows between the downcomer portion 3 and the secondary side 5 in the form of a return circulating flow by the floating effect of the vapor. Accordingly, the membrane boiling can be evaded by the fluidization and the secondary side 5 becomes a nuclear boiling region under a forced fluidization having a high heat transfer characteristic.

Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To realize an output circuit by which the dispersion of output MOSFET of IC and the dispersion of characteristic impedance in a transmission line are coped with and the output impedance is optimized. SOLUTION: The output circuit OC includes an output buffer OB, an input buffer IB, a delay circuit DL constituting an impedance adjusting circuit, a counter CTRH and a CTRL transmission line L or the like. Setting is executed by an RST signal at first and the output impedance of the output circuit OC becomes the max. An impedance adjusting clock signal ZSCK passes through the output circuit OB, returns by total reflection at the far end of the transmission line L, enters the input buffer IB and is compared with Vref. Counting is started in a counter circuit from the transmission start time of ZSCK, an impedance adjusting signal corresponding to a counted value is added to the output buffer OB, a reflection input value is reduced and the input buffer IB is inverted at the time when the value becomes equal to Vref.  The counted value at this time means the optimization of impedance match.

Abstract: PROBLEM TO BE SOLVED: To inspect a defect which is not pierced through a shadow mask, accurately and speedily. SOLUTION: Three cameras 24 to detect a defect in a shadow mask for a cathode-ray tube are provided. The three cameras 24, while they are arranged with a designated slant angle to a plane of the shadow mask 1, photograph a pattern of the shadow mask 1 from an extending direction of each side of an almost equilateral triangle formed by connecting the centers of three holes 2 adjacent each other. Thereby, since the pattern can be photographed from a longitudinal direction of a hollowed defect, a width of the hollowed portion can be seen wide, when moving the cameras 24 and the shadow mask 1 relatively, and also sufficient time to input defect information can be secured, so that accuracy of detection can be enhanced.

IPC: H03K5/13
Filed: 1992-08-07
Abstract: PURPOSE:To obtain an exact delay time by independently controlling a leading time and a trailing time of a pulse respectively. CONSTITUTION:A P-channel MOS transistor(TR) 3 and an N-channel MOS TR 6 of an inverter 1 have a switching function switched by an input signal received from an input terminal 1, a P-channel MOS TR 4 and an N-channel MOS TR 7 have a voltage controlled variable resistance function, and a P- channel MOS TR 5 and an N-channel MOS TR 8 have a function of a fixed resistance. When the input signal changes from a low level to a high level, an ON-resistance of an inverter 1 changes based on a control voltage applied to a control terminal B thereby allowing a leading delay to be controlled. When the input signal changes from a high level to a low level, the ON-resistance of the inverter 1 changes based on a control voltage applied to a control terminal A thereby allowing a trailing delay to be controlled. Moreover, plural delay circuits are used through cascade connection to obtain the signal resulting from the input clock signal delayed by one period, a phase error is detected to increase/decrease a control voltage.

IPC: F16H1/10
Filed: 1987-08-27
Abstract: PURPOSE:To prevent skipping of tooth and to reduce frictional loss by jointing respective rollers rotary slider which rotate while contacting each other rollably on rolling contact sections provided to internal tooth gear and external tooth gear. CONSTITUTION:Upon motion of a toothed belt 13, a floating ring gear 12 and an external tooth gear 9 rotate so as to rotate rollers 14, 15 in a rotary slider 17 thus absorbing differential motion between respective members. When tensile force of the toothed belt 13 varies, e.g. upper tensile force increases in the drawing, the floating ring gear 12 displaces as shown on the drawing. Since respective rollers 14, 15 are arranged so that axes A, A thereof cross with an angle (alpha) and tangential lines E, F at rolling contact sections of the rollers 14, 15 cross with an angle (beta), rollers 14, 15 in respective roller sets function to move the rotary slider 17 to the maximum gap portion in a space S at all times. Differential motion of the rotary slider 17 with respect to the internal and external toothed gears 12, 9 is carried out through rotation of the rollers 14, 15 with scarcely causing slip thus remarkably reducing frictional resistance loss due to the rotary slider 17.

Abstract: PROBLEM TO BE SOLVED: To require no frequency varying means for a power resonator, and to make a device small and low-cost by using a small and low-cost variable condenser as the frequency varying means of a high-frequency oscillator. SOLUTION: In a circuit composed of a high-frequency oscillator 1, a power amplifier 3, a power resonator 4, an exciting coil 5, an electrodeless lamp 6, and the like, the output of the amplifier 3 is applied to the resonator 4 so as to put a resonance condenser 7 and the coil 5 in a resonance state, causing a high-frequency magnetic field to be generated. By providing a variable condenser 2 as a frequency varying means in the oscillator 1 and varying an oscillation frequency, the resonance of the resonator 4 can be properly selected so that the lighting can be conducted. Since respective impedance values can be varied by varying the frequency, even if the value of the condenser 7 and the value of the coil 5 are not varied, impedance matching is conducted so as to perform a drive with excellent efficiency.  Thereby, as no frequency varying means is required for the resonator 4 and the small and low-cost variable condenser 2 is used, a small and low-cost device can be realized.
