IPC: G01R19/165
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To obtain a battery checker by which the normality of a battery can be decided precisely and simply. SOLUTION: A battery 11 as an object to be measured is connected to clips 6a, 6b. Pulse voltages are applied, in the prescribed number of times, to a load Rs which closes a relay only for a prescribed time by an operation from a CPU 3.

Abstract: PURPOSE:To form a simple and small sized measuring device for capacity of sludge by providing optical means of detecting the boundary between a sludge setting part and a supernatant part, and a means of correcting the scale position owing to the difference in the diameter of a measuring pipe. CONSTITUTION:The center of a light emitting device 31 disposed with plural pieces of light sources in one row is matched to the scale position showing half capacity of a measuring tube 1 used. Following to this, the device 31 is tilted to match the light source of the uppermost stage to the scale line L of the measuring tube. The same operation as this is performed with respect to a photodetector 32 disposed opposite to the device 31 with the measuring tube in- between, whereby the scale position owing to the difference in the diameter of the measuring tube is corrected. Next, the sampled sludge liquid is injected into the measuring pipe up to the scale line L, after which the respective light sources are lighted and scanned successively from the lower part. These are converted to electric signals with the photodetector 32, and from the change point in these electric signals, the boundary between the sludge setting part and the supernatant part is detected. In this way, the simple and small sized measuring device for capacty of sludge is formed.

Title: Particle motion simulation system
Inventor: SATO HIROYUKI
IPC: G06F15/173
Filed: 1990-07-13
Abstract: PURPOSE:To reduce the calculation value and to attain the high speed processing in the simulation system by attaining a constitution where each processor calculates the force produced by the interactions caused among the particle data included in its own allocated block by reference to only the particle data on other processors positioned at the right, upper and upper right points respectively. CONSTITUTION:A space including particles is divided into blocks having each cut-off distance where the interactions can be neglected among particles, and these blocks are allocated to the processors 10-1 to 10-9 for each block or every plural blocks, e.g., nine blocks. Each processor refers to only the particle data on other processors positioned at its right, upper and upper right points, e.g., the processors 10-2, 10-3 and 10-6 to a center processor 10-5. Thus the processor 10-5 can calculate the force produced by the interactions caused among the particle data included in its own allocated block. In such a way, the force of a boundary block is calculated between the adjacent processors with no duplication. As a result, the calculation value is reduced and the processing speed is improved in a particle motion simulation system.

Filed: 1982-10-22
Abstract: PURPOSE:To realize stable and highly reliable circuit operation by connecting a serial circuit of a clamping diode and a capacitor and a variable resistor which constitute a time constant circuit between the input and output terminals of the 3rd CMOS-NAND circuit. CONSTITUTION:When a trigger voltage is applied to an input terminal g12 of a CMOS-NAND circuit N1 at a point of time t=0, CMOS-NAND circuits N1, N2, N3, and N4 turn on, off, off, and on respectively. Then a metastable state is entered, but the voltage at an input terminal g3 rises as shown in a figure D according to a time constant C.R and at a point of time t=tw when its recovers up to a cutoff threshold voltage VTH, the circuit N3 turns of as shown in a figure F to invert the circuits N4, N1, and N2, returning to a stable state. At this moment, the clamping diodes operates reversely, so the capacitor C and variable resistor R do not operate as the time constant circuit and the voltage at an input terminal g6 is clamped to the level of a voltage VDD as shown in a figure D. Consequently, no unnecessary forward overcurrent flows in the CMOS- NAND circuits and the stable and highly reliable operation is realized.
