Abstract: A nebulizer capable of supplying oxygen gas of high concentration by increasing the flow rate of the oxygen gas and capable of forming minute aerosol irrespective of a change in the flow rate of the oxygen gas. A nebulizer (A) has a nozzle member (11) for discharging oxygen gas from an orifice (11b), an aerosol forming member (12) mounted at a position corresponding to the orifice, sucking water by suction created by flow of the oxygen gas discharged from the orifice, and forming the sucked water into minute aerosol, and a window (9) and a slit (10) which suck air as the oxygen gas is discharged from the orifice of the nozzle member. The nozzle member (11) has, in addition to the orifice (11b), an oxygen gas outflow section formed in a direction different from that of the orifice and causing supplied oxygen gas to flow thereout according to the pressure of the oxygen gas.

Abstract: A piezo-electric substrate is mainly comprised of a base material and a film formed on one main surface of the base material. In the base material, the main surface on which the film is formed is a roughed main surface. The piezo-electric substrate is obtained by forming the film comprised of a material with a coefficient of linear expansion smaller than a coefficient of linear expansion of the base material on the roughened main surface using a thermal spraying method.

Abstract: The object of this invention is to provide a multiply connected type liquid waste disposal apparatus to unify the kind of canister bottles used for multiple connection, to provide plural patient hoses for separate use, to enable easy visual recognition of a content capacity even if a liquid waste disposing capacity is increased, and to rapidly solidify an absorbed liquid waste.

Abstract: The object of this invention of a float for liquid waste disposal apparatus enables the content inside a container to be easily visually recognizable and allows a faster and steadier solidification of an absorbed liquid waste. The connection plates 5c connects the annular member 5a serving as the guide member to the outer peripheral portion of the cup portion 5b retaining the water-absorptive material 6 wherein the annular member 5a is restrained by the inner wall 26 of the lying member L for preventing the float 5 from revolving in the vertical direction. The liquid waste 21 absorbed from the upper portion and into the lying member L flows downward via the flow path structured with the interstitial portion 27 formed between the annular member 5a and the cup portion 5b and the interstitial portion 28 formed between the inner wall 26 of the lying member L and the annular member 5a.

Abstract: The object of this invention is to provide a float for a liquid waste disposal apparatus having a simple structure for enabling the content inside a container to be easily visually recognizable and allowing a faster and steadier solidification of an absorbed liquid waste. A water-absorptive material 6 is retained inside a spherical float 5 in a manner where a water-absorptive material 6 is wrapped by a water permeable sheet 22 inside a hemispherical primary structural portion 5a and a secondary structural portion 5b capable of being separated into two portions, and thus structured, a circle shaped hole 5c or a square shaped hole 5d of the float 5 serving as a flow path for flowing downward a liquid waste 21 absorbed from an upper portion into a lying member L is formed at the surface of the float 5. The float 5 is contained inside the lying member L in a floatable manner permitted to revolve in a vertical direction.

Abstract: A respiration-synchronized oxygen supplying apparatus includes a sensor detecting respiration of human being, a valve connecting and disconnecting communications between a first gas passage coupled to the human being and a second gas passage coupled to the oxygen supplier, and a controller for controlling the valve based on information from the sensor. A negative pressure generating mechanism is provided having a communication area widened as closer to the human being between the valve and the human being, and a third gas passage is coupled to the negative pressure generating mechanism to normally communicate between the sensor and the human being. During an oxygen supplying state, oxygen does not leak toward the negative pressure sensor, so that the oxygen can be employed without waste.

Abstract: The present invention is concerned with a cleavage type safety valve installed on a metal vessel for affording the explosion-proof function. The safety valve is installed on a small-sized cell vessel which remains hermetically sealed during the normal operation but instantly releases the pressure in the inside of the vessel if, due to abnormalities, such as overcharging, the pressure is increased and reaches a prescribed value to prevent explosion or deformation of the cell vessel. The metal foil type safety valve by the cold pressure welding of the present invention cold welds the metal foil for sealing the air vent hole in the metal vessel. If the internal pressure in the vessel reaches the prescribed value, the metal foil is cleft to form an opening in the vessel to release the internal pressure.
