Abstract: An electromagnetic diaphragm pump has two compression sections operated by an AC. Each of the compression sections comprises an oscillator disposed within a housing and holding a permanent magnet, a pair of diaphragms each having a peripheral portion fixed to the housing and a central portion fixed to an end portion of the oscillator, a pair of field cores sandwiching the oscillator and having magnetic poles displaced relative to the permanent magnet by a predetermined amount, coils for producing magnetic fluxes at the field cores, and compression chambers opposed to end portions of the oscillator, one of walls of each of the compression chambers being formed by an associated one of the diaphragms. The field cores have the magnetic poles magnetized by the AC supplied to the coils, whereby the permanent magnet is alternately attracted and repelled by the magnetic poles to vibrate the diaphragms and to vary the volumes of the compression chambers. The two compression chambers share one field core.

Abstract: The present invention relates to a construction of an explosion-proof safety vent for small-size non-aqueous electrolyte batteries such as prismatic lithium-ion secondary batteries or with an oval cross section hence with a small area of seal plate, and to a method of producing a seal plate. It aims at securing safety of a battery by allowing an explosion-proof vent to operate without fail with a simple construction at no sacrifice of the capacity. In order to fulfill this aim, it provides an explosion-proof safety vent wherein upper peripheral edge of an opening of a bottomed cell container made of metal and the periphery of a seal plate made of metal are hermetically sealed by laser welding, a rivet serving as a terminal is inserted in a through hole provided on the central portion of the seal plate and hermetically fixed by crimping via a gasket, an exhaust hole is provided between the terminal and the periphery of the seal plate, and the exhaust hole is closed by a metal foil.

Each of the second bag bodies includes two bag pieces which are each formed of cloth cut into a foundation.

Abstract: A pump body of a diaphragm pump unit comprises a housing and a pump placed therein, an elastic cover is attached to the housing so as to cover the upper portion of the housing. When the pump is operated with the upper opening of the housing of the pump body being covered with the cover, a fluid such as air is introduced into the housing through an inlet port made therein, flowing into a pressure chamber within the pump body. Since, at this time, the pressure in the housing becomes negative, an attraction force acts on the cover capping the upper portion of the pump body, whereby the cover is put in closer contact with the housing of the pump body to reduce noise leakage.

Abstract: An electromagnetic reciprocating pump having a piston electromagnetically moved at least in one direction is comprised of a frame having attached thereto an electromagnet which operates the piston, an inner cylinder whose one end side in the axial direction is secured to the frame and the other side thereof is closed and having the piston accommodated therein such that the piston can be reciprocated therein, an outer cylinder whose one end in the axial direction being secured to the frame and coaxially encircling the inner cylinder so as to form a working chamber between it and the inner cylinder, an outer piston accommodated within the working chamber so as to freely reciprocate and varying a capacity of working chamber, spring means being contracted and expanded in accordance with the movement of the outer piston, and magnetic coupling means for magnetically coupling the inner piston and the outer piston.
