Title: Substrate-potential supplying circuit
Inventor: ISOBE SADAHISA
IPC: G11C11/401
Filed: 1992-05-12
Abstract: PURPOSE:To make it possible to measure a substrate-potential dependency immediately without a special jig by providing a negative-potential generator, whose active and inactive states can be controlled, and providing a diode, which connects an anode to the substrate and connects a cathode to an external terminal. CONSTITUTION:When a negative-potential generator 2 is in the active state and a negative potential is imparted to an external terminal 6, a substrate current flows to the terminal 6 only when the potential of the terminal 6 is lower than the potential of the substrate by the threshold voltage value or more of a diode 5. Therefore, the potential of the substrate 1 can be measured by slightly changing the potential of the terminal 6 and measuring the current flowing through the terminal 6. When the generator 2 is in the inactive state by a control signal 3, a potential, which is lower than the grounding voltage of the terminal 6 by the threshold value voltage or more of the diode 5, is imparted to the terminal 6. Then, the voltage of the substrate 1 becomes the voltage, which is higher than the terminal 6 by the threshold value voltage of the diode 5. The substrate current can be measured based on the current flowing through the terminal 6. The substrate dependence can be measured by changing the potential of the terminal 6 and measuring the characteristics of a semiconductor integrated circuit.

Title: Ozone catalytic reaction tank
Inventor: ISHIDA KOJI
IPC: C02F1/50
Filed: 1991-05-24
Abstract: PURPOSE:To reduce consumption of motive power and to promote aeration of water to be treated by introducing the water to be treated into a reaction tank by natural flow and equipping the packing material which is externally inserted on a cylinder. CONSTITUTION:Water 15 to be treated is stagnated in a reaction tank 10 while keeping the opening position of the takeout pipe 17 of treated water as the upper-limit water level. Ozonized air 19 is supplied toward an opening 12 of the upper end. Downward flow is generated in the inside of a cylinder 11. The stagnated water 15 to be treated is sucked into the cylinder 11 from the opening 12 of the upper end and becomes a liquid-gas two phases flow and descends through the inside of the cylinder 11. Both the water 15 to be treated and the ozonized air 19 flow out from an opening 13 of the lower end and thereafter become the upward flow and ascend. In the meantime, the water 15 to be treated in the reaction tank 10 is aerated by fine bubbles. In such a way, supply of the water to be treated is performed by natural flow. The need for a pump used for the water to be treated is eliminated and consumption of motive power is reduced. Furthermore since rise of fine bubbles is inhibited and the water to be treated becomes an agitated state, aeration of the water to be treated is promoted by the fine bubbles.

IPC: H02M7/537
Filed: 1992-05-13
Abstract: PURPOSE:To set easily the output frequency and the effective value of the output voltage of a three-phase inverter, in a circuit for controlling the inverter. CONSTITUTION:The output frequency of a three-phase inverter is determined by the selected periods of sine wave data.
