Title: Residual water disposer for underwater pump
Inventor: TSUJIMOTO HARUO
IPC: F04D13/08
Filed: 1986-03-17
Abstract: PURPOSE:To provide perfect drainage at low water level and prevent water from counter flow in the stoppage of a pump by providing a swing valve formed of a cup-like elastic diaphragm on the center portion of a bottom plate of a strainer stand and a plurality of thin water path ports in the annular bottom of the lower surface of the bottom plate. CONSTITUTION:Since negative pressure is generated under an impeller when an underwater pump is activated at the water level l1, a swing valve 8 is operated upward and the peripheral lower edge 12 of a cup-like elastic diaphragm is separated from the bottom plate 7 to afford communication between intake holes 5... and an intake port 3 of pump. Thus, a water path 16 is opened from the lower outer peripheral edge of an annular seat portion 10 to said intake port 3, and water sucked from thin water path ports 11... is discharged through a swirl chamber 1 of pump from the water path 16 and a discharge port without any residual water. And when the underwater pump is stopped at the water level l1 after the completion of drainage, a swing valve 8 is operated downward and the lower peripheral edge 12 of said diaphragm contacts closely to the bottom plate 7 to fulfill the function of preventing counter flow.

Abstract: PROBLEM TO BE SOLVED: To obtain liquid crystal display of multiple gradations and multiple colors by analog data input by outputting one gradation voltage having a specified level of one horizontal period as digital multigradation display data and executing multiple gradations display in accordance therewth. SOLUTION: Analog display data 2 is converted to digital display data of 2-bit by an analog-to-digital conversion means 6. An X driving means 15 takes the inputted digital display data 7 into one block of a latched circuit inputted with the select signal which is 'high' at this time in synchronization with a latch clock 3. When the latch cincuit takes in the digital display date 7 for one fine, mamely, takes in to a latch 640, a horizontal clock 4 is given. A multivoltage level output generating circuit 8 generates the voltages of plural levels meeting the gradations. The voltages of the four values outputted by the X driving means 15 are eventually applied on the liquid crystal elements for one line where the Y driving means 16 holds scanning signals at the voltage levels of the selection voltage 13. Thereby, four gradations display is embodied.

Title: Speed change gear
Inventor: OGURA MASAMI
IPC: F16H61/02
Filed: 1982-04-12
Abstract: PURPOSE:To perform automatic speed change and save power of an engine, by constituting a clutch mechanism through a lap spring arranged to the periphery in a wound tightened condition. CONSTITUTION:At a low rotary speed, centrifugal force acting on a centrifugal weight 10c of a clutch control mechanism 10 is smaller than holding force of a coil spring 10d and a leaf spring 10e, and the weight 10c, in which protrusions in end parts are engaged to each part of the spring 10e mounted to a housing 5, is placed in a brake position. A lap spring 9 directly connects a ring gear 4a to a clutch part 5a, and revolution of an engine 1 is transmitted in proportion 1:1 to a pulley 3 in the output side. If the revolution of the engine 1 reaches at least a fixed speed to increase centrifugal force, the weight 10c rides across the protrusion of the spring 10e to spread in the diametric direction and release a brake. Then the engine 1 decelerates to rotate the pulley 3 by reduction ratio provided to planetary gears 4.

Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To prevent an unnecessary warning, and to prevent sudden departure of a vehicle by announcing the presence of an obstacle according to an announcing signal outputted when confirming a continuance ranging over setting time of an accelerator pedal nonoperating state in a state where the obstacle exists in the vehicle advancing direction and a shift range is set in a travel range.

Title: High strength copper alloy
Inventor: MATSUMOTO TATSUHIKO
IPC: C22C9/00
Filed: 1989-03-15
Abstract: PURPOSE:To combinedly provide the copper alloy with high electrical conductivity and high mechanical strength by dispersing specified amt. of Mo fibers having specified average diameter and aspect ratio into a copper matrix. CONSTITUTION:By volume, 0.5 to 30% Mo fibers having <=2mum average diameter and >=25 aspect ratio are dispersed into a matrix constituted of copper. Or, Mo alloy fibers contg. one or more kinds of elements having <=0.5wt.% maximum solid soln. degree into copper are dispersed thereto. Since Mo materials hardly enter a solid soln. into copper, the deterioration of the electric conductivity of the copper alloy dispersedly incorporated into the matrix is extremely less and, on the other hand, the strength of the copper alloy can be increased.

Title: Variable intake controller for internal combustion engine
Inventor: YOSHIOKA MAMORU
IPC: F02B27/02
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent an unnecessary lowering of the performance of an engine while improving the durability of an operating part by prohibiting change over of intake conditions only when it is really necessary. SOLUTION: The intake conditions of an engine 1 is changed by opening and closing an intake control valve 25 on the basis of a command from an electronic control unit(ECU) 30. When engine cooling water temperature detected by a cooling water temperature sensor 37 is lower than a predetermined value and the abrasion of each operating part of the intake control valve 25 is easy generated, the ECU 30 prohibits the opening/closing action of the intake control valve 25 in a range where the changing speed of an engine speed is larger than a predetermined judged value.  Hereby, the opening/closing operation of the intake control valve 25 is prohibited only under a condition that abrasion is easily generated, therefore it can attempt compatibility between the improvement of the durability and reliability of each operating part and the prevention of the unnecessary lowering of the performance of the engine 1 by the prohibition of the opening/closing operation of the intake control valve 25.

Title: Filament winding process
Inventor: ASAKAWA KAORU
IPC: B29C53/80
Filed: 1983-04-08
Abstract: PURPOSE:To prevent the fluffing and the damage of a fiber bundle by moving a throttle plate to follow the moving passage of the fiber in such a manner that the running direction of the fiber almost does not change, using the movable throttle plate, when the fiber impregnated with resin passes the throttle hole. CONSTITUTION:A resin reinforcing fiber F is drawn out from a bobbin around which said fiber is wound and is introduced into the impregnating liquid in a resin bath 3 through a guide 2. The fiber F is impregnated with resin, passing the fiber through the resin so as to rotate rollers 4. The fiber advances through the flexible guide exit pipe 10 fixed to a flange 9, and excess resin is removed at a throttle hole 6 provided on a throttle plate 5. Then, because the flexible guide exit pipe 10 has been set so as to direct the throttle plate 5 to a desirable direction, the fiber is guided in almost constant direction without changing its running direction from the position of the rollers 4 and is wound around a deformed mandrel 7 by a specified wound number. Thus, as the change of passing angle of the resin impregnated fiber drawn out from the throttle hole is kept small, the fluffing and the damage of the fiber bundle may be obviated.

Abstract: PURPOSE:To obtain both focus and tracking control signals, by using two subbeams having the modulated intensity for control of the main beam and the focus and for control of tracking to detect the change of the received quantity of secondary beams at a 4-split photodetector. CONSTITUTION:The main beam W given from a 3-element semiconductor laser 11 and subbeams X and X' applied with the intensity modulation irradiate a disk 18 via a collimator lens 12, a beam splitter 13, a 1/4 wavelength plate 14 and a condenser 15. The reflected light from the disk 18 goes back ward and is reflected by the splitter 13 to be made incident to a 4-split photo detector 17 of a single array. The irradiating positions of the beams X and X' are separated from each other on the basis of separating points 17x and 17z from the beam X. Then a focus control signal is obtained from variations of an output A2+A3-(A1+A4) of each of detectors 17a-17d. While a tracking control signal is obtained from the change of an output difference A1+A2-(A3+A4) corresponding to the beams X and X' and based on a separating point 17y.
