Title: Preventing means for abnormal vibration of pressure reducing valve
Inventor: YOKOYAMA TAKESHI
IPC: F16K47/02
Filed: 1987-04-08
Abstract: PURPOSE:To eliminate the influence applied to a pressure reducing valve by securing such a mechanism where a valve body having an orifice at its center has displacement against the energizing force of a spring set in a casing when the secondary side pressure has a sudden change and the increase value of the secondary side pressure is ejected to outside through a hole drilled through the casing to outside. CONSTITUTION:When the primary side pressure has a normal slow change, a fluid can pass freely through an orifice 88 having a diameter smaller than those of pipes set before and after the orifice 88. However, the fluid cannot pass completely through the orifice 88 in case the pressure rises up due to a sudden change of pressure caused by the water hammer of a pipe set at the secondary side. Thus, the fluid displaces a valve body 90 toward the exit side against the force of a spring 92. Then, the side face of the body 90 opens an injecting port 94 and the fluid of the high pressure is ejected into the air. As a result, an instantaneous high-pressure fluid does not flow to a lower chamber of a diaphragm 28 and therefore both the diaphragm 28 and a pilot valve can have the normal stable actions. Thus, a pressure reducing valve is not affected even though the water hammer is produced.

Title: Endoscopic device to be percutaneously inserted
Inventor: TANAKA TOSHIKAZU
IPC: A61B1/00
Filed: 1995-03-22
Abstract: PURPOSE: To form the space necessary for the interior of the celom without damaging the parts exclusive of a through-hole at the time of insertion of a guide member by providing the interior of the treating means insertion channel of an endoscope having an angle part to direct a front end in an arbitrary direction with an operating wire attached with magnetic members at the front end and providing the channel with magnets capable of attracting the magnetic members from outside. CONSTITUTION: The magnetic members 21 of abdominal cavity floating members projecting from the front end of the insertion part 2 of a laparoscope 1 are inserted into a sheath pipe 11 and after all the magnetic members 21 are dropped into the abdominal cavity, the insertion part 2 is introduced from this sheath pipe 11 into the abdominal cavity. An operator pulls the knob parts of a first set of the abdominal cavity floating members to press the magnetic member 21 to the front end of the insertion part 2. The operator curves the angle by operating an angle knob in this state to carry the magnetic member 21 to a prescribed position. The magnet 30 is attracted and the abdominal cavity wall is floated when the magnetic member 21 is carried to the region of the magnetic field by the magnet 30. The space is then formed with the peritoneum.  Other two sets of the floating members are similarly discretely operated, by which the space having the prescribed spread is formed in the abdominal cavity.

Abstract: PURPOSE:To cause an air direction deflection plate to be smoothly deflected in a predetermined direction under e reciprocating movement of a rod by a method wherein as a rotary member is rotated, a rotating part of coupling member fixed to an engaging projection is moved while rotating along an outer circumferential surface of the projection part of the rod. CONSTITUTION:A motor 15 at a side of a main body 1 of an air conditioning grill is rotationally driven. and its rotating part 17 at its lower surface is rotated. The rotating part 17 is fitted and fixed to a concave part 19a of a cylinder part 19 at an upper surface of a rotary plate 18, so that the rotary plate 18 is rotated and an engaging projection 20 at the lower surface is similarly rotated. Since the engaging projection 20 is engaged into a longitudinal hole 14a of the projection 14 at an end part of a rod 11 in such a way as it may be moved, the engaging projection 20 is reciprocated within the longitudinal hole 14a while rotating and at the same time the rod 11 is reciprocated in rightward and leftward directions. As the rod 11 is moved in rightward and leftward directions, a pair of engaging projections 13c of a cam 13 engaged in the engaging concave part 12 of the rod 11 are moved rightwards and leftwards, thereby a fan-like cam 13 is rotated around its pivot part. As a projection 10e of a link 10 is rotated, a connecting plate 8 is moved rightwards and leftwards.

Abstract: PURPOSE:To lower the contact resistance of an electrical contact material made of an Ag-Sn alloy and to prevent an excessive temp. rise by heat-treating the contact material to lower the concn. of the metallic solute contg. Sn in the surface part and carrying out internal oxidation. CONSTITUTION:An Ag-Sn alloy contg. 4-25wt% metallic solute contg. Sn is heat-treated in a nonoxidizing or reducing atmosphere to lower the concn. of the metallic solute in the surface part by partial sublimation or evaporation of the solute. The heat-treated alloy is internally oxidized. Thus, the concn. of the oxide of the metallic solute in an electrical contact material made of the internally oxidized Ag-Sn alloy in the vicinity of the surface is made practically equal to or lower than the average concn. level so as to lower the contact resistance. The Ag-Sn alloy may be internally oxidized and heat-treated to partially reduce or extract the oxide of the metallic solute in the surface part.

Filed: 1978-07-19
Abstract: PURPOSE: To reduce power consumption, to prevent gas leakage, and to reduce cost by controlling the sparking in an ignition zone by utilization of the forward voltage changes of a diode which is heated by the combustion of a burner.  
     CONSTITUTION: With a power switch 2 made, an oscillation is conducted by a circuit consisting of a transistor 5, transfomer 3, and the like. A capacitor 9 is charged by the oscillation. When the charge voltage exceeds 160V, for example, a current flows in a shockley diode 10 and is boosted by a transformer 11 to generate a spark in an ignition zone 13. Once the combustion of the burner has started, diodes 7 1  and 7 2  are heated and the forward voltages increase so that the oscillation is stopped. Thus, power is saved.

Abstract: PURPOSE:To obtain a cement dispersant capable of increasing fluidity, preventing the deterioration of fluidity with the lapse of time and improving workability by using a specific water-soluble vinyl polymer as a component. CONSTITUTION:The cement dispersant is composed of the water-soluble vinyl polymer having 5/95 to 95/5mol ratio of a structural unit expressed by the formula I to a structural unit expressed by the formula II. In the formulae, each of R<1> and R<2> represents H or methyl, M represents alkali metal, alkaline earth metal, ammonium group or organic amine group, X represents bivalent group, each of R<3> and R<4> represents H or methyl, R<5> represents H or 1-3C alkyl, n represents 2-3, m represents 1-100 and Y represents-CH2- or -CO. A cement compound containing the cement dispersant is high in dispersibility among the cement particles, small in the change in the dispersibility with the lapse of time and free from the generation of setting retardation. Since the problem of slump loss of the cement compound is solved and setting retarding property is not shown by using the cement dispersant a high quality concrete is produced without increasing the working time of cement execution.
