Title: Flow control of fluid spray equipment
Inventor: DEIBITSUDO CHIYAARUZU GIRU
IPC: G01F25/00
Filed: 1988-06-28
Abstract: PURPOSE: To make it possible to easily return fluid by a pressure equalizing means which equalizes the pressures in and out of a container when the fluid flows through an outlet into the container and when the fluid returns from the container through the outlet to the sprayer. CONSTITUTION: This fluid sprayer is provided with the container 14 and the pressure equalizing means consisting of holes 50, 52 and a tube 54. The container 14 is provided with a means 16 for connecting the inside of the container 14 and the outlet 58 for releasing the fluid to the circumference during the normal use of the sprayer 8 and connecting the container fluidtightly and removably to the sprayer 8. The pressure equalizing means equalizes the pressures in and out of the container 14 when the fluid flows through the outlet 58 into the container 14 and when the fluid returns from the container 14 through the outlet 58 to the sprayer 8.  The fluid released into the container 14 during the measurement is returned by gravity through the sprayer then through the outlet to its original container by, for example, inverting the sprayer by using the device for flow rate regulation, by which the easy return of the fluid is made possible.

Title: Semiconductor dynamic ram
Inventor: MIYATAKE HIDEJI
IPC: G11C11/408
Filed: 1987-06-24
Abstract: PURPOSE:To reduce the number of refreshment cycles and to prevent a defect in refreshment while holding a refreshment busy rate constant even a RAM becomes large in capacity by refreshing unselected memory cell arrays at the time of refreshing operation. CONSTITUTION:One decoder between row decoders 1 and 2 enters a selection state with an external signal through decoding signals for dividing operation of memory cell arrays 4 and 5. Then word line driving signals RX1 and RX2 for dividing operation go up to a high level and one word line each in arrays 4 and 5 is held at the high level. Then sense activating signals S1 and S2 for the dividing operation go up to the high level to perform sense restoring operation. Thus, when a row address refresh counter makes one round up to a row address RAi, all cells of the arrays 4 and 5 are refreshed. The frequency of refreshment is therefore increased and a defect in refreshment is precluded.

IPC: F04D9/00
Filed: 1994-07-11
Abstract: PURPOSE:To provide a low cost and good performance of an automatic priming device for a pump by automatically adding priming water by means of the automatic falling of water in a hermetically sealed type tank and vacuum thereby generated in the tank. CONSTITUTION:When a water falling value 12 is opened by switching ON of a water priming command, water in a tank 1 falls through a water falling piping 11 and the inside of the tank 1 is evacuated accordingly. At the same time when the water falling valve is opened by means of the water falling command, the intake valve 15 of an air intake piping 14 is opened and thus air in a pump 2 and a suction piping 6 is sucked through the intake piping 14 to the upper part of the tank 1. Simultaneously, water is sucked up from the bottom end of the suction piping 6 according to a vacuum degree. A water level in the suction piping 6 rises together with the advance of falling of wate in the tank 1 and priming water into the pump 2 is completed. At this time, the water level in the tank 1 is detected by means of an electrode bar 25-2 and the water falling valve 12 is closed. Then, the pump 2 is driven so as to function as a specified pump.

Filed: 1990-06-18
Abstract: PURPOSE:To generate a head part G with a feeling close to that on an actual vehicle by making the center of rotation of rolling moton of a model tow- wheeler higher and higher as the vehicle speed becomes faster and faster. CONSTITUTION:A control means 40 controls the center of rotation of the rolling motion of the model two-wheeler to higher height as the vehicle speed increases. In the rolling motion, G(acceleration) applied to the head part of the rider is generated in proportion to the rolling rate (rolling angular velocity), and consequently a differnt phenomenon (travel feeling) from actual one is generated, but the rolling center is varied to enable G control which is not proportional to the rolling rate. Consequently, the head part G with the feeling which is close to that in an actual travel can be generated.

Title: Coaxial waveguide converter
Inventor: TANAKA TSUNETOSHI
IPC: H01P1/06
Filed: 1979-12-03
Abstract: PURPOSE:To increase the accuracy of manufacture and the efficiency of manufacture, by interposing an insulator between the gap of inner conductors at coaxial part opposing to converted sections. CONSTITUTION:An insulator 9 having low dielectric constant is coated on the entire external surrounding of an inner conductor 4 of a coaxial part 2. The thickness of the insulator 9 is taken as several tens mu. Since the impedance of the coaxial part 2 and a choke 5 is changed due to the dielectric constant epsilon of the insulator 9 through the coating, the coaxial part 2 and the choke 5 are designed taking into account the dielectric constant epsilon. Thus the coating of the insulator 9 to the inner conductor 4 can avoid strict accuracy of fitting and tolerance of the concentricity among a door knob 3, bearings 7 and the inner conductor 4 in the manufacture and assembling, allowing ease of manufacture and assembling.
