Title: Binary random number generator
Inventor: IZUMI TERUYUKI
IPC: G06F7/58
Filed: 1981-12-14
Abstract: PURPOSE:To set the initial value of an n-stage shift register which generates the n-order maximum period train signal having a high irregularity from the beginning reproducingly, by using the n-order maximum period train generating circuit and the m-order maximum period train generating circuit. CONSTITUTION:An n-notation counter 6 is cleared from a reset signal 4 at first, the output operates a changeover switch 7 and selects an m-order maximum period train generating feedback signal line. At the same time, a Q output of an FF3 preset with the preset signal 4 generates the m-order maximum period train signal. When n-set of signals generated are transferred to an n- stage shift register, since the n-notation counter 6 outputs an overflow signal, the changeover switch 7 connects the n-order maximum period train generating feedback signal line to the FF3. Further, the n-order maximum period train signal taking the m-set of series of the m-order maximum peroid train is generated. Thus, after a time of nT from the reset signal, a binary random number having very high irregularity can be obtained.

Title: Method and device for shortening memory-fetch time
Inventor: SHIYUU KON CHIYAN
IPC: G11C29/42
Filed: 1991-07-18
Abstract: PURPOSE: To speed up the operation of a computer memory system by changing the timing of the DRAM recovery part of the fetch operation of a semiconductor memory chip constituting a system memory. CONSTITUTION: As soon as partial rows are entered into an SRAM in a fetch operation. the SRAM is cut off from a DRAM and the recovery process of the DRAM is started. In this case, the number of machine cycles required for fetch and access is remarkably reduced by overlapping a DRAM recovery and the data output of the SRAM on the chip. Then, in the operating example of this method and device, a fetch time is significantly shortened to be 32 cycles. This is achieved by making the data gap between row fetch transfers on data busses of the memory from 21 cycles to zero and becomes the improvement of about 40%.

Filed: 1985-09-13
Abstract: PURPOSE:To control fuel concentration in anolyte within a specified range independent of anolyte temperature by detecting electrolyte concentration is anolyte, and maintaining electrolyte concentration within a specified range by adding fuel and solvent. CONSTITUTION:Anolyte comprising 1.5mol/l of sulfuric acid, 1mol/l methanol and the balance water is accommodated in an anolyte tank. The anolyte is circulated through a cell main body and returned to the tank through an anolyte passage 3. Supplementary tanks of water and methanol are mounted outside the anolyte tank, and their supplements are controlled so as to keep each concentration constant. Since methanol and water are consumed by power generation, sulfuric acid concentration is detected with a hydrogen ion meter utilizing a concentration cell, and water is supplemented according to the concentrated amount. The consumption of methanol is detected with a liquid level sensor mounted to the tank, and methanol is supplemented to the anolyte tank from the methanol supplementary tank to the original level. Thereby, sulfuric acid concentration is kept within a specified range.

IPC: F24C7/02
Filed: 1983-10-28
Abstract: PURPOSE:To prevent a dangerous operation caused by runaway, by resetting forcibly a processing circuit which is running away, by a normal processing circuit, even if any processing circuit of a system runs away. CONSTITUTION:When a processing circuit 2 runs away by static electricity, etc., a processing circuit 6 operates and transfers a forced reset signal to the processing circuit 2, and the processing circuit 2 is set to an initial state. Subsequently, it executes regular control and transfers a data to the processing circuit 2. In this way, if it is supposed that a system has run away under the influence of static electricity, it is considered that the influence by a key unit 10 is the largest, and it can be estimated that the processing circuit 6 used for reading a key through a line l 10 has run away. The processing circuit 6 does not transfer a regular pulse to the processing circuit 2, therefore, the processing circuit 2 decides that the processing circuit 6 has run away, the processing circuit 6 is set forcibly to a reset state, the processing circuit also attains a reset state by itself, and all is returned to the initial state.

IPC: F04B9/02
Filed: 1993-08-17
Abstract: PURPOSE:To easily change a peripheral turn moving speed of a squeeze roller brought into pressure contact with a pumping tube. CONSTITUTION:An operating lever 59, when it is operated to be turned along a guide plate 61, is fitted into a recessed part provided in the guide plate 61 by energizing force of a leaf spring 58.
