Abstract: A device for distributing compressed air from a compressed air source to a plurality of apparatus that use compressed air. The device comprises a housing having valve chambers, inlet ports for connecting the valve chambers to the compressed air source, outlet ports, and exhaust ports communicating with outside the device. Each outlet port is adapted to communicate with at least one of the apparatus that use compressed air. Spherical valve bodies movably are provided in the valve chambers, respectively, each for closing one inlet port and one exhaust port. Shafts extend from the valve bodies, respectively. Each shaft has an end portion passing through one exhaust port and protruding from the housing. Electromagnetic actuators are coupled to the end portions of the shafts, respectively.

Abstract: The present invention relates to a casting apparatus for formation of a resin-made membrane which is made to be capable of accomplishing a stable pressure reduction through a suction chamber irrespective of the dimension of an interval between a die and a cooling roll. Thus, in the apparatus according to this invention, a suction chamber is disposed independently of a die and is located to define a necessary seal gap with respect to a cooling roll. Further, a circumferentially moving mechanism is provided to shift the suction chamber along the circumferential directions of the cooling roll while maintaining the necessary seal gap. This invention is applicable, for example, to a biaxial oriented film machine, a non-oriented film machine, a sheet machine, and others.

Abstract: A rotary pump comprising a pump unit having a pump and a motor unit separated from the pump unit and having a motor for driving the pump. The rotary pump further comprises a watertight housing enclosing the motor and including a non-magnetic wall made of material which permeates magnetism, an input section attached to the pump, an output section attached to the motor and opposing the input section, with the non-magnetic wall interposed between the output section and the input section, and at least two magnets, one of which is fixed to that surface of the output section which opposes the input section, and the other of which is fixed to that surface of the input section which opposes the output section.

Abstract: A bathtub having a pump, comprising a tub having side walls one of which has an inner surface, an outer surface, and a thin portion made of magnetically permeable material, pump means secured to the inner surface of the thin portion, for taking in hot water from said tub and pressurizing the hot water, motor means secured to the outer surface of the thin portion and opposing said pump means, and a magnetic coupling means for mangetically connecting said pump means and said motor means.

Abstract: A nozzle device for jetting water as hot as one can enjoy bathing in it, which is supplied under pressure from a hot water supply source, into hot water in the bathtub comprising a nozzle body provided with a nozzle opening formed at the front end of the nozzle body and through which the hot water is jetted and an inner hole through which the hot water is introduced from the hot water supply source to the nozzle opening, a means for jetting not water passed through the nozzle opening, having a hole arranged coaxially with the nozzle opening and a passage through which air outside is introduced into the hot water passed through the nozzle opening, and a means for adjusting the amount of the air introduced through the air passage into the hole, said means being movable toward said nozzle opening while rotating around its axis.

Abstract: A gas separation/extraction apparatus comprises a tank for separating and extracting a specific gas element from a gas mixture, the tank containing an adsorbent for adsorbing the gas element from the gas mixture, a pump having a cylinder and a piston housed therein, the pump being adapted to alternately pressurize and decompress the inside of the tank as the piston reciprocates, a first three-way solenoid valve connected between an exhaust port of the tank and a suction port of the pump, a second three-way solenoid valve connected between a discharge port of the pump and the suction port of the tank, and a pressure balance unit connected between the second three-way solenoid valve and a suction port of the tank, and adapted gradually to eliminate a difference in pressure between the tank and the pump as the tank is switched from a decompressed state to a pressurized state.

Abstract: An electromagnetically reciprocating apparatus includes a piston assembly which is driven by an electromagnet repeating magnetization and demagnetization and a compression coil spring so as to reciprocate a front and rear pistons of the assembly in a front and rear cylinders. An air hole is formed in the rear cylinder to communicate a sealed inner space partitioned in the cylinder by the rear piston with an atmosphere. A valve is mounted on the air hole to adjust a resonance frequency of the vibration system of the apparatus.

Abstract: This disclosure relates to a massage arrangement of the pneumatic type comprising a mat body provided with a plurality of juxtaposed air chambers, said mat body being subjected over the entire or local surface to repeated rhythmic wave motions involving expansion and contraction by repeating a successon of feeding and discharging of compressed air into and from said air chambers, whereby effective and stable massage is applied not only to the waist and back regions but also the neck and shoulder regions.

Abstract: A massager is composed of a linear compressor having a piston reciprocated by force of electromagnetic attraction to produce compressed air at a safe pressure with a relatively small difference between the rated pressure and the maximum pressure, a distributor for allowing the compressed air fed from the compressor to be selectively discharged therefrom and a bag having a plurality of air tight sections which are successively expanded by receiving the compressed air fed from the distributor.
