Abstract:
When used for connecting a fluid carrying pipe, the pipe joint for a fluid handling device of the present invention can provide a strong force for preventing the fluid carrying pipe from coming out from the pipe joint and can assure excellent sealing properties regardless of variations of the fluid temperature. The present pipe joint is arranged such that no fluid stay portion is formed. A cylindrical joint body is provided at the inner peripheral surface thereof with a receiving port into which a one-end pushing portion of a fluid carrying pipe is inserted, and at the outer peripheral surface thereof with a male screw portion. This joint body is formed integrally with the main body of the fluid handling device. Formed at the receiving port is a sealing portion inclined with respect to the axis thereof. A sealing ring having a sealing portion which comes in contact with the sealing portion of the receiving port, is pressingly inserted into one end of the fluid carrying pipe. By the threaded movement of a pushing ring as threadedly connected to a male screw portion on the outer periphery of the joint body, a sealing force is provided to both sealing portions.

Abstract:
The invention provides a fluid apparatus in which two or more kinds of chemical liquids can be rapidly stirred and mixed in a pump to a uniform concentration. A barrier membrane such as a bellows or a diaphragm that is reciprocally moved in the axial direction is disposed in a pump body so as to form a liquid chamber between the barrier membrane and an inner wall of the pump body. A suction port and a discharge port are disposed in the inner wall of the pump body. Supply pipes for the two or more kinds of chemical liquids are pipe-connected to an inlet portion of the suction port so as to join together. An outlet portion of the suction port is disposed in a side face of a protruding forward end of a suction check valve which is fixed to protrude from the inner wall of the pump body into the liquid chamber, whereby the outlet portion is opened so as to eject the two or more kinds of chemical liquids toward a circumferential wall in the liquid chamber. Therefore, the two or more kinds of chemical liquids which are separately supplied to the pump body are ejected from the outlet portion of the suction port so as to circulate along the circumferential wall of the liquid chamber. This circulating action causes the liquids to be stirred and mixed rapidly and uniformly in the liquid chamber.

Abstract:
A fluorescent lamp unit includes a fluorescent lamp having a bulb constituting one discharge path, said bulb including three U-shaped tube portions, a lighting circuit operatively connected to the fluorescent lamp for lighting the fluorescent lamp, and a cover part having a cap at one end thereof and having a globe at other end thereof for containing the lighting circuit and the fluorescent lamp. Each of the three U-shaped tube portions has a pair of straight tube portions provided straight in a direction along to a basic center axis of the fluorescent lamp unit and has a bent portion being bent so as to be convexly curved toward the globe side opposite to the cap side thereby to form substantially U-shape and linking the glove side ends of the pair of straight tube portions. The straight tube portions are arranged equidistantly on a circumference of a certain radius from the basic center axis. The three U-shaped tube portions are formed so that minimum gaps c1, c2a, and c2b between the inner surface of the globe and each of the outer surfaces of the globe side ends of the three U-shaped tubes have substantially a same length.
Abstract:
In a pipe joint made of resin in accordance with the present invention, a primary sealing is formed between an inner ring pressingly inserted into an insertion portion of a pipe at its one end to increase the diameter thereof, and the joint body into which the insertion portion of the pipe increased in diameter, is being inserted. When the threaded connection of a pushing ring to the joint body is advanced, a sealing force is applied to the primary sealing. The inner ring has an inner diameter equal to that of the joint body and that of the pipe, assuring a smooth movement of a fluid in the pipe without the fluid remaining at the joint.
