Abstract: PURPOSE:To obtain a highly efficient power supply equipment by providing a main switch between a DC input power supply and sub-switch means of a half-bridge opening and closing in a predetermined period, a serial resonance circuit containing an output transformer. CONSTITUTION:Transistors 20a and 20b are formed as sub-switch means and are alternately switched, and a transistor 22 controls the inflow from input Va to a resonance circuit by using main switch means. A diode D4 detects an error signal of an output generated at a load resistor R5 of a photocoupler 12 near zero value of a resonance current of a D-FF24. When a transistor 23 is turned on, the transistor 22 is turned off, the inflow from the input power supply Va to the resonance circuit is prohibited but oscillating state continues, and energy taken to the output is reduced and its output voltage drops. Then, the transistor 23 is turned off, the transistor 22 is turned on and its energy is supplied from the power supply Va, and an amplifier 25 gives the secondary induced voltage of a transistor 21 to the D-FF24.

The obtained conjugate fiber is washed with boiling water and drawn followed by drying, under blowing air at <=80 deg.C against the fiber, to the water content of <=20wt.%. Subsequently, the fiber is dried to make it dense to obtain the objective hollow acrylic fiber of 5-40% in a percentage of hollowness, having continuous hollow parts between the core part and the sheath part in the fiber direction.

Filed: 1988-09-22
Abstract: PURPOSE: To enable increase in the number of combinations of win without changing the number of symbols per reel and the number of reels provided on this machine by using first and second tables which are not equal in return rate. CONSTITUTION: When a contest starting switch is depressed, one random number is selected per reel in one set. Then, a table is selected to determine which of a table A and a table B should be used to generate a different average return to contestants for determining the symbol of the reel to be displayed subsequently. After the selection of the table, the random number generated by a random number generator is converted to a symbol code, which is transmitted to a stepping mechanism controller for control the rotation of reels. As a result, the main mechanical controller gains a notice that the rotation of the reel is completed. Then, when a win is decided in the combination of the reel positions, payment is accomplished to meet the requirement. When the selection of the table A and the table B is made truly at a random, the machine presents a plenty of return to the contestant.

With the pressure difference between those of a vacuum meter 51 and a vacuum meter 52 the gas discharge speed from the sample chamber 22 is obtained. The gas discharge speed of the sample 6 is obtained by reducing the gas discharge speed from the sample chamber 22 into which no sample is charged. In measuring a sample whose gas discharge speed is extremely small the sample 6 carried to the sample chamber 22 is heated by a heater to a certain temperature. Accordingly, it is possible to measure the gas discharge speed of extremely small sample.

Abstract: PROBLEM TO BE SOLVED: To measure a mode characteristic value from which a Doppler shift component is subtracted. SOLUTION: A wave transmitter which is moving in a propagation characteristic measuring device 11 outputs a sound wave having a constant angular frequency of ωo . The sound wave is received by a wave receiver so that a wave receiving signal is obtained.

Phase compensation is executed so that it becomes a wave receiving signal at the same time to obtain a sound propagation characteristic. In order to execute the accurate measurement of a frequency of the receiving wave signal, an interpolation operation section 13 executes an interpolation operation of the frequency spectrum. A peak detection operating section 14 calculates a peak ωp of the frequency of the interpolated frequency spectrum.  A phase compensation operating device 15 compensates the phase of the sound propagation characteristic by a Doppler shift component. A Hankel transform processing section 16 applies Hankel transform over the sound propagation characteristic, then a peak detecting operating section 17 detects the number of peaks in the frequency spectrum.
