Title: Operating method of division damper
Inventor: TANAKA OSAMU
IPC: B03C3/36
Filed: 1994-04-27
Abstract: PURPOSE:To prevent the discharge of dust, scattered in accompanied by the opening of a division damper, from a chimney and eliminate the' abrasion of the division damper. CONSTITUTION:An upstream damper is arranged in the entrance of respective load divisions and a downstream damper is arranged at the outlet port of the same while a desulfurizing tower is arranged at a downstream side. Upon closing a division damper, the downstream damper is closed at first and, subsequently, the upstream damper is closed. Upon opening the division damper, the upstream damper is opened at first and, subsequently, the downstream damper is opened. Dust, scattered in accompanied by the opening and closing of the upstream damper, is attracted to a dust collecting pole in an electric dust collector. Further, the flow of gas to be treated is stopped upon the opening and closing of the upstream damper whereby abrasion in the upstream damper can be restrained. Dust, scattered in accompanied by the closing of the downstream damper, is removed by a desulfurizing and denitrating tower.

IPC: C08L5/00
Filed: 1989-04-12
Abstract: PURPOSE:To obtain a laminated material with non-porous properties and porous properties by constituting it of a porous layer consisting of chitosan and constituted of a three dimensional network structure with three dimensional network open-cell and a non-porous thin film layer consisting of chitosan. CONSTITUTION:A chitosan acidic aq. soln. is prepd. by dissolving chitosan in an acid aq. soln. and a part of said chitosan acidic aq. soln. is extended into a sheet, which is freeze-dried to form a porous sheet of a chitosan salt. Separately, the remaining part of the chitosan acidic aq. soln. is extended into a thin film, which is dried by evaporation to form a non-porous chitosan salt thin film. While the non-porous chitosan salt thin film is not completely dried or after one face of the dried thin film is made damp with water and it is laminated and adhered on one face of the porous sheet of chitosan salt. The laminated body is neutralized by treating it with an alkali aq. soln. to insolubilize thereby the laminated body in water and the obtd. water-insoluble chitosan laminated body is dried. The chitosan laminated material consists of the non-porous thin film layer and the porous sheet layer and is useful for a covering material of a wound and can be also used for such applications as a water retention agent and a filtering material.

Abstract: PURPOSE: To facilitate the adhesion of a piezoelectric element and reduce the variation in the properties of droplets by a method wherein an piezoelectric element and a diaphragm having a thin part are connected to each other through only a peripheral part and a thicker part of the diaphragm.  
     CONSTITUTION: The piezoelectric element 25 and the diaphragm 22 for a substantially circular pressure chamber 21 are connected to each other through the thicker parts 23, 24 formed at the peripheral part and the central part of the diaphragm 22. When an electrical signal is impressed on the piezoelectric element 25 in the manner of a bimorph, the element 25 is deformed into a conical shape toward the pressure chamber 21 and depresses the thicker part 24 of the diaphragm 22, the diaphragm 22 is deformed, the internal volume of the chamber 21 is rapidly reduced, the internal pressure of the chamber 21 is raised and the resulting pressure wave causes a droplet to be jetted from a nozzle 27 through a passage 26. When the electrical signal is removed, the element 25 and the diaphragm 22 are returned to their original states, the pressure chamber 21 is expanded and the ink in an ink tank flows in through a coupling 28 and a passage 29.

Title: Vibration isolator
Inventor: KANAI FUMIAKI
IPC: E04B1/36
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent rolling of a seismically isolated body so long as an external force directly applied to the seismically isolated body does not exceed a predetermined value, by setting a conically concave surface at a suitable straight ascending gradient from an upper surface of a base plate to the periphery, and forming a concave portion having a predetermined slanting surface at the central portion of the upper surface of the base plate. SOLUTION: A base plate 1 has a concave portion 11a formed at a central portion of an upper surface 11 thereof, which concave portion has a slanting surface at a gradient of an angle θ1 larger than a slanting angle θ of a slanting surface (conically concave surface), with a diameter L. The slanting surface is, similar to the upper surface 11, set at a straightly ascending gradient from the center to the outside, and the diameter L of the concave portion 11a is smaller than a diameter L1 of a bearing ball 2.  Provided that a dimension between contact points of the bearing ball 2 to the concave portion 11a is set to L2, if a relationship of L2<=L<L1 holds, an externally operating force for rolling the bearing ball 2 on the concave portion 11a becomes larger than an externally operating force for rolling the same on the upper surface 11 which is the slanting surface at the periphery of the concave portion 11a.

Title: Multitime window type ultrasonic switch
Inventor: ISHII HIROMITSU
IPC: G08B13/16
Filed: 1990-04-06
Abstract: PURPOSE:To clearly display the height of an object by dividing the time required in the detection of the reflected wave of an ultrasonic wave into a predetermined number of time windows and detecting the object in the respective time windows. CONSTITUTION:A worker confirms the lighting state of a display device 3 and sets the display device 3 so as to cancel the receiving signal in a time window W1 with respect to a table 6 by an input apparatus 4. Since a control apparatus 5 neglects the receiving signal in the time window W1, the receiving signal 14 from a wall is not mistaken for an object to be detected. Therefore, the control apparatus 5 confirms that only the receiving signal in a time window W3 is the object to be detected and allows only the light emitting element I3 corresponding to the time window W3 within the display device 3 to light. By this method, the worker can clearly know the height of the object to be detected.

Title: Data carrier and identification system
Inventor: FUKUOKA SHINICHIRO
IPC: G06K17/00
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To extend a communication range in the identification system consisting of a reader/writer and a data carrier. SOLUTION: A carrier of a prescribed frequency is sent from a reader/writer and a resonance circuit 2 of a data carrier 1 receives the carrier. The data carrier detects a distance with the reader/writer based on a voltage level. When the distance is small, a shunt resistance of a shunt circuit 4 is decreased and when the distance is high, the shunt resistance of the shunt circuit 4 is increased. Thus, the optimum shunt resistance is selected independently of a communication distance and data transmission from the data carrier 1 to the reader/writer is ensured.

Title: Direction control valve
Inventor: MATSUMURA SHIZUO
IPC: F16K11/07
Filed: 1982-05-31
Abstract: PURPOSE:To prevent the flow-rate of regenerated flow from being influenced even if a cotrol member is set unstable by a fluid pressure by installing an ON/ OFF valve which permits only the circulation from an oil passing hole to a communication chamber, at the opened edge of the oil passing hole formed on a control valve body arranged in a valve hole on one side of a spool. CONSTITUTION:When a seat part 39 is opened, the return oil from an actuator port 3 flows into a bottom-side chamber 5 through a through-hole 46 and a supply flow passage 11, and the opening area of a tank flow-passage port 27 substantially reduces, since the tank flow-passage port 27 corresponds to a bulged part 42, and the rate of flow which returns to a tank is restricted. Therefore, the return oil from a rod-side chamber 6 is regenerated efficiently in the supply flow-passage 11. In this case, as an ON/OFF valve 44 is opened by the difference between the pressure in the oil passing hole 38 and the force of a spring 45, the opening area is kept constant.
