Title: Purifying device
Inventor: TANAKA TETSUYA
IPC: A01G31/00
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a purifying device using an energy saving and maintenance saving fluidized bed type filtration system. SOLUTION: Maintenance working is facilitated by mounting so as to sink the lower part of plural fluidized bed type filter tanks 1a-1c under water in a water area of an objective lake and marsh and to expose the head part thereof above the water surface and the power consumption necessary for aeration is reduced by allowing a water to be treated supplied to each tank to contact with air to replenish oxygen. And recovering working is saved by storing the purified water in a sedimentation tank to settle a sludge after filtering and transporting the sludge to a sludge pond to solar-dry.

Title: Operation of electric dust collector
Inventor: KITAJIMA KIMIO
IPC: B03C3/66
Filed: 1982-04-13
Abstract: PURPOSE:To suppress the deviated excitation of a high-voltage transformer, by synchronizing the time of charging high-voltage electricity and the time of suspending the charge of electricity with the voltage of a power source. CONSTITUTION:The time of charging high-voltage electricity and the time of suspending the charge of electricity are synchronized with the point zero of the voltage of a power source, and said time of suspending the charge of electricity is selected at a desired integer times one or more cycles of the voltage of the power source to intermittently charge a dust-precipitating part with electricity. In addition, the time of charging high-voltage electricity is set up to (n+1/2) cycles of the voltage of the power source to perform the intermittent electrification. Hence a relatively large rush current for charging which flows at the initial stage of recharging after the suspension of charging electricity is put in positive and engative polarities, to uniformalize the loads both of position and negative currents on a power-controlling means and a high-voltage rectifier. Thus, the deviated excitation of the high-voltage transformer is suppressed, and the inhibition of the inferior ignition of the power-controlling means, etc. are contrived.

Title: Semiconductor device
Inventor: IZUMI SATOSHI
IPC: H01L29/78
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To eliminate a discontinuous shape at the terminal ends by bonding terminal ends of adjacent trench lines, and effectively utilize the viscous flow of an oxide film in a heat treating process to reduce a stress occurring at the trench line terminal ends at oxidizing. SOLUTION: Terminal ends 2 of adjacent trench lines 1 are bonded together in a bond block 10 with gentle curves thereof at the block 10 without leaving discontinuous parts of each trench line 1, thereby avoiding blocking a viscous flow of an oxide film at the ends 2 to relax the stress caused by the oxidation. This suppresses the dislocation.

Title: Hydraulic equipment
Inventor: MASUDA KENJI
IPC: F15B11/16
Filed: 1983-04-07
Abstract: PURPOSE:To reduce power loss and give priority to speed control of one of the actuators that is subjected to the highest load pressure by communicating via a shuttle valve a load pressure in the rear position of each of variable orifices of a plurality of flow rate and direction control valves, with a pressure in a back pressure chamber of a pressure control valve which opens and closes the passage between two ports. CONSTITUTION:A pressure control valve 30 is operated in accordance with a difference between fluid pressure on the side of a primary port 24 and in a back pressure chamber 32, namely, a difference between pressures in front of and behind a flow rate regulating variable orifice 19 so as to open and close the passage between the secondary and primary ports 25 and 24, whereby controlling the quantity and the pressure of fluid discharged by a variable pump 1 in accordance with the opening of the flow rate regulating variable orifice 19. The pump therefore will not discharge any excess fluid and the difference between pressures in front of and behind the flow rate regulating variable orifice 19 may be controlled to exhibit a constant value which corresponds to a spring pressure of a spring 33, thereby providing small power loss. One flow rate regulating variable orifice 19a, for example, behind which the highest load pressure is exhibited is selected by shuttle valves 42a and 42b and the pressure is propagated into the back pressure chamber 32 of the pressure control valve 30 to control the difference between the front and behind pressures, so as to give priority to the speed control of an actuator 50a which is subjected to the highest load pressure.

Title: Dynamic semiconductor memory
Inventor: YAMAZAKI HIROYUKI
IPC: G11C11/407
Filed: 1988-03-15
Abstract: PURPOSE:To reduce the size of a dynamic semiconductor memory by using a substrate bias voltage generating circuit which performs intermittent actions via an oscillation means both as a voltage holding means for a timer means which produces a timing signal for refresh and a word line driving signal generating means. CONSTITUTION:A timer means 3 and a voltage holding means 21 can always work based on the output of a ring oscillator 2. At the same time, the output of a substrate bias voltage generating means 1 is detected and ON/OFF switching control is applied to the means 1 via the oscillator 2 based on the output voltage of the means 1. In other words, an intermittent action state can be set by a switching control means 5 so that the means 1 is actuated only when required. Thus the oscillator 2 itself is always working together with reduction of power consumption. As a result, the oscillator 2 can serve as the means 21 and the means 3. Then it is possible to use the oscillator 2 both as the means 21, the means 1 and the means 3 respectively. Thus the size of a dynamic semiconductor memory can be reduced.

IPC: H01J61/56
Filed: 1985-03-25
Abstract: PURPOSE:To prevent increase of lamp current thus to prevent burning of ballast by arranging a solid organic bridging member in the outer tube while connecting in parallel with a light emission tube and providing a fuse which will blow off or the current higher than referential level in the base. CONSTITUTION:Solid organic bridging member 10 is connected in parallel with the supporting wires 2a, 2b connected to the electrodes at the opposite ends of a light emission tube 1 while a fuse 11 is provided in the base 5. The bridging member is composed of porous organic material having fine holes 12. Upon leakage of Na from said tube 1, the outer tube 3 is filled with Na vapor and small Na particles are adsorbed to the porous organic material thus to lower the resistance considerably thereby the lamp current will increase to flow current higher than referential level through the fuse 11 thus to blow off the fuse 11 and to interrupt power supply. Consequently, the increase of lamp current due to elimination of Na in the light emission tube caused through leakage of Na is prevented resulting in protection of ballast from burning.
