Title: Compound valve
Inventor: WADA TADASHI
IPC: F04B53/10
Filed: 1984-06-22
Abstract: PURPOSE:To operate a valve body using its own resources by action of a fluid in a pipeline by providing a valve connected to the suction side of a pump. CONSTITUTION:When the discharge side of a pump reaches a designated pressure, a pressure switch 7 is turned on, so that an electric current is applied to a solenoid valve 6 to be opened. A cylinder chamber 32 is connected to low-pressure suction side of a pump through a pilot tube 4, so that a fluid in the cylinder chamber 32 flows out to the pump suction side. Thus, the pressure in the cylinder chamber 32 is lowered below the pressure of an outflow chamber 18. A valve body 33 is separated from a valve seat 22 by pressing force from the outflow chamber 18 side to open a valve port 21, and when a piston portion 37 contacts the upper wall 10b of a valve casing, the valve port is fully opened.

IPC: H01P11/00
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To reduce the area occupied by insulating parts watched from the side of a mounting surface and to attain miniaturization in the width of the same terminal conductor by forming a first insulating part on the mounting surface and forming a second insulating part from the mounting surface to both end faces which is adjacent to it. SOLUTION: On a mounting surface 16 of a dielectric resonator 10 on which a terminal conductor 22 is formed, a first insulating part 23 is formed for insulating the terminal conductor 22 and an outer conductor 14. From the mounting surface 16 of the resonator 10 to both side faces adjacent to it, namely on the two side faces of the resonator 10, a tapered second insulating part 24 is respectively formed so as to link an opening end face 15 and the first insulating part 23. As a result, on the side of the opening end face 15 of the resonator 10, a connecting conductor 21 and the terminal conductor 22 communicated to it are insulated from the outer conductor 14.  Thus, the area occupied by the second insulating part 24 as viewed from the mounting surface 16 is reduced, the width of the terminal conductor 22 can be widened, and the resonator 10 can be miniaturized for the width of the same terminal conductor 22.

Abstract: PURPOSE:To prevent brightening line position from being varied by operation of an oscilloscope and the temperature, etc., by measuring DC offset voltage of a vertical axis amplifier and cancelling the offset voltage by feeding back the offset voltage. CONSTITUTION:A switch 16 is actuated by a switch control signal 17 synchronous with an outside signal or a brightness cancelling signal, and input terminal of an attenuator 2 is grounded. And, an offset voltage output 8 from a vertical axis amplifier 3 is converted to a digital value by an A/D converter 10 synchronously with a switch control signal. This digital value is added to an input value of the D/A converter 13 by an adder 12 through a coefficient operator 11, and a result of this addition is converted to an analog value by the D/A converter 13 and put into the vertical axis amplifier 3. It is possible, by doing so, to cancel the offset voltage of the  vertical axis amplifier to zero and eliminate necessity of adjustment of the offset  voltage.

Abstract: The invention relates to a process for the manufacture of substantially pore-free shaped articles of polycrystalline material such as aluminium oxide, titanium boride, silicon nitride or silicon carbide, in which pulverulent materials or preformed articles having pores open towards the surface, in a vacuum-tight sealed glass casing that has a viscosity of less than 106 Pas at the pressing temperature employed, are isostatically hot-pressed in a high-pressure autoclave using an inert gas as pressure-transfer medium. By being embedded in a flowable pile or by having a layer applied to them in the form of a suspension, the glass-encased powders or articles are brought into contact with a heat-resistant pulverulent material that, upon softening of the glass casing, penetrates into the surface of the glass of reacts with it, with the result that the glass casing is reinforced from the outside at the pressing temperature. As pulverulent materials, there may be used titanium boride, graphite, SiC or boron nitride, which do not react with the glass casing, or glass powder or silica, which react with the glass casing to form a glass melt of at least the same viscosity as, or of a higher viscosity than, the glass casing.

Title: Suction device for internal combustion engine
Inventor: OKUMURA TAKESHI
IPC: F02M35/10
Filed: 1979-10-12
Abstract: PURPOSE: To generate a powerful swirl in a combustion chamber in a low-speed running and increase a charging efficiency in a high-speed and high-load running by forming a mixture outlet which opens above a helical suction port and communicating the outlet with a communication passage common to each cylinder.  
     CONSTITUTION: A mixture from a carbureter 24 is sent to an inlet passage A from an intake manifold 24. Some of it flows along upper wall faces 17, 18 and is accelerated because those faces gradually get narrower toward a crossing point W'. After passing the crossing point W', the mixture is forced to run along a side wall face 15 of a spiral part B in a spiral direction C by a wall face 11a of a projection containing a cylindrical hollow. The downward swirl generated in the spiral part B causes the other mixture flowing into an annular outlet 13, to be swirled. Thereby, a powerful swirl in a spiral direction B occurs at the annular outlet 13. While passing through a clearance formed between a suction valve 5 and a valve seat, the swirl grows more and flows into a combustion chamber 4.
