The concentrated oxygen introduced through the inlet port 1 for concentrated oxygen is raised in flow velocity and reduced in pressure in the a straw part by the Venturi effect effect of the Venturi pipe 4. Therefore, the water is sucked through the inlet pipe and mixed with the condensed oxygen, whereby the condensed oxygen is humidified. The excessively sucked water is dropped onto the water surface since the terminal of the Venturi pipe 4 is opened within the vessel, and utilized again for humidification.  On the other hand, the humidified concentrated oxygen is discharged thorough the discharge sport 2 of the lid 6, and guided to a supplying device to a patient.

Title: Continuous ventilator
Inventor: MATSUMOTO MITSUO
IPC: F24F7/02
Filed: 1987-11-25
Abstract: PURPOSE:To prevent a deformation of cross bar and prevent a ventilation flow by a method wherein the cross bar is formed into an arch and a net is installed at the cross bar. CONSTITUTION:An upper side 9 of a rib plate 5 is inclined toward a central part of a ventilation unit.

Title: Production of high carbon steel strip
Inventor: MIYAZAKI HIDEAKI
IPC: C21D1/70
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To produce a high carbon cold-rolled steel strip while unnecessitating annealing after pickling by coating a decarburization-inhibitor containing glass component on the high carbon steel strip after hot-rolling, applying a batch-coil annealing and cold-rolling after shot-blasting. SOLUTION: The decarburization-inhibitor having good seal function composed of >=50% glass component melted at about 600 deg.C or lower and the balance aggregate such as Al2 O3 , etc., is coated in a thickness of 60-180μm on the high carbon steel strip containing >=1.0wt.% C after hot-rolling and, thereafter, the annealing treatment is applied at >=650 deg.C in the bell-type batch coil annealing furnace. By this method, a scale decarburization in a reducing atmosphere is prevented at the time of annealing. Thereafter, the decarburization-inhibitor and the seal are removed by the shot-blast and, successively, the steel strip is cold-rolled. By this method, in the production of the high carbon steel strip showing the uniform shape and characteristics, and comparatively soft quality and good workability, the times of the annealing, a lead time and the production cost can be reduced.

Title: Button cover for controller of video game machine
Inventor: TANAKA TOKIHIRO
IPC: A63F13/98
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a button cover for the controller of a video game machine capable of preventing steins and reducing strains exerted on fingers. SOLUTION: This button cover is adhered to a direction button on the controller of a video game machine with an adhesive double coated tape. The button is formed by adhering circular rubber 1 to a cloth 2 with an adhesive agent 3. The deflection of the rubber 1 between the direction button and a finger causes the finger to fit over the direction button. The cloth 2 comes into contact with the finger at the time of operating the direction button to prevent the finger from slipping and to absorb sweat from the finger. In addition, the adhesive double coated tape is cut into the same shape and size as the direction button. As the direction button in a complicated shape (e.g. the shape of a cross, etc.) can be operated as one large circular button with this button cover, the operation of the controller becomes easier and strains exerted on the finger is reduced.
