Title: Ac synchronizing crystal watch
Inventor: TAMURA TATSUYA
IPC: H03L7/00
Filed: 1982-02-05
Abstract: PURPOSE:To eliminate an integral error of a crystal oscillator and to maintain high accuracy, by applying synchronism to a dividing circuit of output of a crystal oscillating circuit that advances the display time after detecting the 0 cross point of the output voltage of a rectifying circuit of commercial power supply voltage. CONSTITUTION:The output of a crystal oscillator Q is divided by dividing circuits D1 and D2, and the time is displayed at a display part DS by a driving circuit DR. A commercial power supply AC is rectified by a rectifying circuit A and applied to a transistor TR1. For the output of the TR1, a pulse is generated at the 0 cross point of the output of rectification. This pulse is applied to a gate circuit G directly or via one-shot pulse generators W1 and W2. In such a way, it is possible to apply synchronism to the circuit D1 with the output of the circuit G in the case of both 50Hz and 60Hz of commercial power supply frequency. As a result, the errors are not integrated to always keep high accuracy within a fixed range. Furthermore no effect of service interruption is caused, and a malfunction due to noises can be avoided.

Abstract: PURPOSE:To successively lower the resistance value of a heat generating resistor, by mounting a pulse generation circuit and a resistance meter and applying a peak value higher than the preceding one to a heat generating resistor from the pulse generation circuit by a calculation part when the resistance value, after a voltage pulse was applied, is equal to or more than a predetermined value. CONSTITUTION:The peak value Vs of apply voltage, the set signal of the numbers (n) of pulses ad a START signal are applied to a pulse generation circuit 10 form a calculation part 12. After the above mentioned set pulse is applied to a thermal head 7, of which the resistance value is equal to or more than a predetermined value R0, from the above mentioned circuit 10, the resistance value thereof is measured by a resistance meter 11. Because the resistance value of a heat generating resistor is not lowered when the peak value of a voltage pulse is low, the above mentioned measured value is sent to the calculation part 12 and compared with the preceding measured one by CPU14 and, when the lately resistance value is low and higher than the predetermined value R0, the peak value Vs is set so as to be made high by DELTAV and a voltage pulse is applied to the above mentioned thermal head 7 from the pulse generation circuit 10. By this method, the resistance value of the heat generating resistor is gradually lowered to the predetermined value R0 or less to eliminate irregularity.

Title: Method for sticking disks to each other, and device therefor
Inventor: KASHIWAGI TOSHIO
IPC: G11B7/26
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To substantially prevent the occurrence of local warpage by irradiating adhered disks with UV rays in the state of placing these adhered disks on a flat surface, then diffusing the heat of the adhered disks heightened in temp. to a disk loading surface and taking the adhered disks out of the disk loading surface after the temp. of the adhered disks is nearly equaled to an ambient temp. SOLUTION: A quartz table GS8 and a quartz plate GB8 are reversed to each other in the direction of wind blowing to make the quartz table GS8 lower in temp. than the quartz plate GB8 to diffuse the heat at the time of irradiation with UV more to the quartz table GS8 side. The heat is radiated to the flat disk loading surface side in the state that the adhered disks are held in tight contact with the loading surface and, therefore, the adhered disks shrink by cooling earlier from the side in tight contact with the loading surface but the adhered disks are corrected by the flat surface and the occurrence of the warpage is substantially prevented. The surface of the adhered disks is pressed to the loading surface side by their own weight and the temp. of the adhered disks may be lowered down to the ambient temp. while the flat state is maintained.

Title: Hydraulic circuit
Inventor: CHIBA MINORU
IPC: B21B31/32
Filed: 1981-02-12
Abstract: PURPOSE:To reduce the time for exchanging of rolls considerably by keeping the remaining quantity discharged by a pump for giving rolling force of hydraulically loaded rolling mills or the like accumulated via a sequence valve on a branch circuit. CONSTITUTION:The oil pressure supplied with a pump 11 controls the rolling forces of  work rolls 3 via a valve 54, a pipeline 73, a servo valve 8, a cylinder 4, and a reinforcing rolls 2. On the other hand, a sequence valve 5 is so designed that the excess oil  pressure is supplied to a pipeline 77 when the required max. pressure is attained in the  pipeline 73, and the pressure is accumulated by this in an accumulator 52. In the stage  of exchanging the work rolls, the valve 8 is set at center valve position upon stopping  of rolling, and pipelines 82, 83 are interrupted by a selector valve 63, then pipelines 81,  91 are conducted by a selector valve 60 so that valves 57, 58 are opened by the oil  pressure and the oil pressure in a cylinder oil chamber 6 is released. The oil pressure  in the accumulator 52 is supplied through pipelines 78, 83 into an oil chamber 7, whereby the time T1 is reduced considerably. The accumulator 52 restores high pressure in  the time T2 because an accumulator 9 is high in pressure and the volume of the chamber 7 is small. This high pressure is similarly utilized for raising of the roll 2, whereby  the time T3 is reduced considerably.
