Title: Detecting device for fall of moving body
Inventor: FUJIWARA HIROTSUGU
IPC: G01B7/00
Filed: 1984-11-20
Abstract: PURPOSE:To detect the fall of a body which moves up and down by arranging winding elements at the uppermost and lowermost ends of the movement path of the moving body and their intermediate part in consideration of their winding directions. CONSTITUTION:When the magnetized moving body 2 is inserted up to a winding element 1b, voltages developed across winding elements 1a and 1b are equal to each other because of the mutual inductances between the winding element 1c and winding elements 1a and 1b and the elements 1a and 1b are connected in the opposite winding directions, so a signal to an AC/DC converter 6 is canceled. When the body 2 passes through the element 1b, the voltages developed across the elements 1a and 1b becomes equal to each other, and consequently the signal to the converter 6 is generated. Further, when the body 2 passes through the element 1a, the voltages developed across the elements 1a and 1b become equal again and the voltage signal to the converter 6 disappears. The output of the converter 6 is connected to an A/D converter 7-1 and converted into a digital signal, which is stored in a storage device 8.

IPC: G06T1/00
Filed: 1992-08-24
Abstract: PURPOSE:To digitize a video signal in which the area of a two-dimensional code is small by setting an appropriate reference voltage even in a fly-back period and obtaining a digital signal even in the start period of the video signal. CONSTITUTION:A preset voltage is set the voltage almost at the center of the amplitude of the video signal. Then, a control signal is turned off in fly-back periods t1-t2, and t3-t4,..., and turned on in the periods t2-t3,... of the video signal. That is, analog switches A and B are turned off, and an analog switch C is turned on in the fly-back period, and the terminal voltage of a capacitor is set the preset voltage. On the other hand, the switches A, B, and C are inverse operated in the period of the video signal, and the capacitor 3 is charged and discharged by the video signal. Therefore, the video signal in which the area of the two-dimensional code is small can be digitized by a binary signal string in which the higher state of the video signal than the reference voltage is turned on and the lower state is turned off by a comparator 1.

Title: Inverter power supply
Inventor: TAKAHASHI YASUSHI
IPC: H02M3/28
Filed: 1990-09-19
Abstract: PURPOSE:To suppress surge voltage and a current flowing into an inverter transistor upon turn ON of a power supply circuit by providing a circuit for discharging a capacitor in a DC power supply circuit at the output thereof. CONSTITUTION:Discharge time of a capacitor 5 can be set arbitrarily by selecting the resistance of a discharge resistor 11, i.e., a discharge constant. Consequently, discharge time of a capacitor 5 can be shortened and the voltage can be suppressed at the time of reclosing of power supply. Current flowing into inverter transistors 6, 7 can thereby be suppressed at the time of reclosing of power supply and at the same time surge voltage due to that current is suppressed thus protecting a transistor against breakdown. According to the constitution, inverter transistors 6, 7 having small capacity can be employed resulting in reduction of the size and the cost. Furthermore, fluctuation of the discharging time of the capacitor 5 can be suppressed within the error of the constants of the capacitor 5 and the discharge resistor 11.

Abstract: PURPOSE:To speed up processing by executing processing for retrieving plural different divided values in parallel, and between respective processors and a specific processor, collectively transmitting/receiving the information of partial intermediate values, a total intermediate value and the group of the succeeding retrieving range for the plural divided values. CONSTITUTION:The intermediate value of elements in each retrieving range at every divided value is found out as a partial intermediate value and these partial intermediate values are collectively sent to the specific processor. The specific processor finds out the intermediate value of these partial intermediate values as a total intermediate value, finds out the total intermediate value at every divided value to be charged and collectively informs a value corresponding to all the divided values to be charged to all processors. Elements in respective retrieving ranges are sorted by the informed respective total intermediate values and the number of elements smaller than the total intermediate value and the number of elements equal to the total intermediate value are collectively informed to the specific processor. Each specific processor sums the number of informed elements, and at the time of discriminating that an element corresponding to the order of the divided values is equal to the total intermediate value, sets up the element as a required divided value. Consequently, a divided value can be retrieved within a short time.

The number of turns of the coil of a control circuit C is three times as large as that of a circulating circuit R. When a load circuit M is closed and an amplifying circuit B and the circulating circuit R are closed and the control circuit C is closed, a circulating current 11 generated in the circulating circuit R is three times as large as a control current 12. The under current 13 having the same magnitude as the control current 12 and the diamagnetic current 2 having two-fold magnitude of the current 12 are generated in the amplifying circuit B.
