Title: Solenoid valve
Inventor: MASUMOTO NOBORU
IPC: F16K31/06
Filed: 1988-03-01
Abstract: PURPOSE:To suppress the delay of the opening/closing time by installing a seat for opening/closing a communication hole which communicates to a flow-out passage side in the lower part of a plunger installed in a main valve body and forming a fine hole which communicates to a flow-in passage in a main valve body side part. CONSTITUTION:When a solenoid coil 14 is applied with an electric current, a plunger 12 is raised by the magnetic force of a stator iron core 11, and a seat 5 in the lower part of a pillar-shaped main valve body 16 opens a communication hole 33, and the pressurized water on an inflow passage 21 side flows to an flow-out passage 22 side through a fine hole 31 on the main valve 16 side part. The pressing force acting toward a valve seat 3 side which is applied onto the main valve body 16 is reduced by the flow to the flow-out passage 2 side, and the main valve body 16 is raised by the magnetic force due to the stator iron core 11 in the upper part of the main valve body 16, and the valve seat surface is opened.

Title: Backwashing type filter
Inventor: KAWAKAMI SHIGEZOU
IPC: B01D24/02
Filed: 1981-03-30
Abstract: PURPOSE: To make pressure drop low, the stripping effect of fibrous materials from filter media high and backwashing efficiency high by forming a filter bed with many spherical filter media of uniform diameters, and installing agitating venes in this filter bed.  
     CONSTITUTION: A net plate 6 is extended in central part in a filter body 1, and many spherical filter media 7W are laminated in a tight contact state on the plate 6, whereby a filter bed 8 is formed. While the liquid to be filtered which flows into the body 1 through an inflow port 2 passes through the clearances among the media 7Win the bed 8, fibrous materials such as glass fibers are captured. When the pressure drop increases on account of the clogged bed 8, washing liquid is fed through a diacharge port 3 and agitating vanes 9 are rotated to agitate and flow the filter media groups 7W of the bed 8. The stripping of the fibrous material is increasingly activated by the agitating effect of the vanes 9 and the backwashing effect is much improved.

Title: Flow rate control valve
Inventor: HASHIMOTO TORU
IPC: F02D41/22
Filed: 1989-02-28
Abstract: PURPOSE:To improve reliability in control by detecting the rotational output of a rotating actuator driving a flow meter control valve so as to obtain its actual opening, outputting a drive command in response to the result of comparison between the actual opening and a target one, and thereby concurrently making failure judgement based on the rotational output. CONSTITUTION:An ISC valve 10 opens/closes the valve by means of a DC motor via a feed screw mechanism in a device wherein the ISC valve 10 and a first idle air valve 16 acting as a flow rate control valve are arranged in parallel with a bypass passage 2A going around a throttle valve 7 within a suction passage 2. In this case, a rotational output detecting means (not shown) outputting pulse signals synchronized with the rotation of the motor is provided so that the actual opening of the ISC valve 10 is detected based on the pulse signals. Then, a drive command is outputted in response to the result of comparison between the actual opening and a target one based on the operational condition. It is concurrently judged that failures occur when no pulse signal is outputted by the rotational output detecting means at the time of outputting the drive command.

Title: Nickel-zinc battery
Inventor: KAWAKAMI AKIHIRO
IPC: H01M50/417
Filed: 1982-03-25
Abstract: PURPOSE:To prevent internal short-circuiting from being caused by zinc dendrite, by interposing a selective permeation film such as an ion-exchange film plated  with nickel, between an anode and a cathode plates together with a separator. CONSTITUTION:As the charging and discharge of a battery is repeated several hundred times, zinc would go into a film separator 9 and easily pass through another separator 8' and reach an anode plate 1 to cause internal short-circuiting. This phenomenon would be caused by the metal zinc of a cathode plate reduced by the charging. To prevent the phenomenon, a selective permeation film 10 such as an ion-exchange film plated with nickel is interposed between the separators 8, 8', 9 so that zinc dendrite comes into contact with the nickel to produce hydrogen gas and changes into zinc oxide as shown by a formula Zn+H2O ZnO+H2. The zinc oxide is gradually dissolved into the electrolyte so that the zinc oxide disappears. The zinc dendrite is thus kept from passing through the separator 8' and coming into contact with the anode plate 1.

Filed: 1982-03-26
Abstract: PURPOSE:To reduce installation areas, by disposing a chain which circulates and moves between the sewage in a sewage treatment tank and the atmospheric air in said tank, attaching plastic filter media to the chain and forming the organism films thereon. CONSTITUTION:Sewage is fed from a raw water tank 14 into a sewage treatment tank 11, and a chain 12 is turned so as to bring the organism films of plastic filter media 13 into contact alternately with the sewage and the atmospheric air.

IPC: G03G15/01
Filed: 1986-03-06
Abstract: PURPOSE:To obtain an excellent color image having no color mixing easily at a high speed by specifying the quantity of spectral diffraction of each exposed light when a photosensitive body with a color separating function is exposed entirely to specific light and developed with a specific color repeatedly. CONSTITUTION:The photosensitive body which is constituted by forming an insulating layer formed of respective color filters on a photoconductor and has the color separating function is cbarged electrostatically and exposed to image light, and then a charge density image corresponding to each color light beam is formed at the boundary between the filters and photoconductor layer. Entire-surface exposure is performed by using light which is transmitted through one kind of filters and then a latent image is formed on the filters and developed with corresponding color toner. This process is repeated to form a color image. The quantity Ii of spectral diffraction is specified according to an expression and then boundary charges are prevented from being removed owing to the leak of entire-surface exposure light passed through adjacent filters, so that an excellent image which has no color mixing is formed easily at a high speed. In the expression, Ijo is the quantity of spectral diffraction with which a potential generated by image exposure is nearly equal.
