Title: Facilitating method of low-temperature nuclear fusion reaction utilizing radiation
Inventor: GESHI JIRO
IPC: G21B1/00
Filed: 1990-04-17
Abstract: PURPOSE:To increase sharply the probability of a nuclear fusion reaction by the collision of excited deuteron by providing a radioactive material for a deuteron system in a state of density as high as possible. CONSTITUTION:Typical radioactive metal radium emits three kinds of radioactive rays, alpha, beta and gamma rays. Among them, the alpha ray is a helium neucleus of heavy mass, and when particles of the helium neucleus having a positive charge emitted at a high speed and of a deuteron neucleus having the same positive charge as the former collide with each other, in the case of this alpha ray, the deuteron neucleus is accelerated. The helium neucleus is decelerated slightly and its speed slows down with each of repeated collisions, secondary and tertiary, or it becomes a lithium neucleus temporarily in trapping, which contributes to a nuclear fusion reaction. According to this constitution, no possibility of radioactive contamination or the like in a fission reaction occurs, although a radioactive material is used.

Title: Nonvolatile semiconductor storage device
Inventor: KOBAYASHI MASANORI
IPC: G11C29/00
Filed: 1985-05-13
Abstract: PURPOSE:To measure directly the transistor characteristics of a memory cell obtained after writing, by using a control circuit which applied the voltage of a program power supply system to a word line of the memory cell and can select only the current supplied to the memory cell to flow it to a power supply and then setting a control mode for said control circuit. CONSTITUTION:For a control circuit having the circuit constitution where three memories are selected by an EPROM, a signal 12 is set at a high level with a signal 8 turned off respectively. Thus no current is flowed from a program power supply. While a signal 14 is set at a low level and it is possible to supply the voltage that can cover a voltage range required to obtain the voltage Vth through V-I measurement to a node 9 since a transistor 6 is depressed. Then no current flows to other circuits on a CD basis owing to CMOS. Therefore, the above-mentioned state is set for measurement of the program power supply voltage and the current flowed from a lead power supply to secure square characteristics. Then voltage/current characteristics can be obtained as shown in the diagram. As a result, the voltage Vthp can be measured directly after programming of the EPROM with high reproducibility and high accuracy within 0.1V.

Title: Vibration damper
Inventor: TAKEHARA SHIN
IPC: F16F9/50
Filed: 1987-04-24
Abstract: PURPOSE:To generate a large damping force without requiring a large mass by providing an orifice at a bulkhead supported elastically at a piston rod, and a small diametered fluid passage connecting fluid chambers in a cylinder on both sides of the bulkhead. CONSTITUTION:In case of a piston rod 12 being displaced relatively to a cylinder 1 following the relative displacement between a car wheel support member and a car body, fluid circulates in fluid chambers 4a, 4b through an orifice 9 at a bulkhead 5 supported elastically by a spring plate 6 and generates damping force, when the relative displacement is slow and also an amplitude is large. On the other hand, when the relative displacement is rapid and also the amplitude is small, the orifice 9 at the bulkhead 5 falls into the state of being blockaded, and damping force is generated against the vibration of a specific frequency by the resonance phenomenon of a vibration system by means of a small diameter fluid passage 8 connecting both fluid chambers 4a, 4b with each other. Thus, a large damping force can be generated without requiring a large mass as compared with a dynamic damper.

Title: Control method for single-phase inverter
Inventor: OKAMURA KOICHI
IPC: H02M7/48
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To realize effective utilization of element rating by changing over the switching operation of a switching element with a fundamental wave and the switching operation with a PWM wave for every one cycle of the fundamental wave, thereby averaging the loss between arms constituting an inverter circuit. SOLUTION: A PWM wave is generated by a comparator 4 from an output from f of an oscillator 1. Then, a signal of f/2 is generated by a frequency divider from fundamental wave, and by using this signal, the switching element operation of each arm 61, 62 of an inverter circuit 6 is changed over by one cycle by a logic circuit 8. That is, the switching operation by the fundamental wave and the switching operation by the PWM wave are changed over by the period of the fundamental wave. Because of this, an element rating existed in the inverter circuit can be selected, even though the switching frequency has increased. Therefore, by selecting an optimum element, it becomes possible to reduce the cost of equipment and make its size more compact.
