摘要： 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.

摘要： 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.

摘要： It is an object of the invention to, even in the case where liquid containing a sedimenting material such as slurry is used, prevent sedimenting and aggregation from occurring in a pump. As means for attaining the object, a bellows 7 that is extendingly and contractingly deformable in the axial direction is placed in a pump body 1 with setting the axis B of the bellows vertical so as to be driven to perform extending and contracting deformation, and form a liquid chamber 9 inside the bellows 7. A suction port 18 and a discharge port 19 are formed in an inner bottom face 4a of the pump body 1 facing the liquid chamber 9. Liquid is sucked from the suction port 18 into the liquid chamber 9 by extension of the bellows 7, and the liquid in the liquid chamber 9 is discharged from the discharge port 19 by contraction of the bellows 7. The inner bottom face 4a is formed into a conical shape in which the face is downward inclined as moving toward the discharge port 19. Therefore, also liquid containing a sedimenting material such as slurry can be always smoothly discharged toward the discharge port 19 along the downward inclined face of the inner bottom face 4a without collecting on the inner bottom face 4a of the liquid chamber.

摘要： The present invention relates to a pipe joint made of resin which is preferably used in, particularly, piping for a liquid having high purity or ultrapure water. In the pipe joint made of resin, a pipe receiving port 11 of a joint body made of resin 1, an inner ring 3, and a pressing ring 5 form primary, secondary, and tertiary sealing portions 10, 20, and 30. The primary sealing portion 10 is formed by a pressingly contacting area between a primary seal receiving face 13 of the joint body 1 and a primary seal urging face of the inner ring 3, thereby generating a seal contact pressure in an axial direction. The secondary sealing portion 20 is formed by pressingly contacting areas between secondary seal inner and outer receiving faces 15 and 16 of the joint body 1 and secondary seal inner and outer urging faces 36 and 37 of the inner ring 3, thereby generating a seal contact pressure in a radial direction. The tertiary sealing portion 30 is formed by a pressingly contacting area between a tertiary seal receiving face 17 of the pipe receiving port 11 and a tertiary seal urging face 71 of the pipe 7, thereby generating a seal contact pressure in an axial direction. According to the invention, high skill and experience are not required in a connecting operation, and an excellent sealing property is ensured for a long term.

摘要： A quartz pipe joint of the present invention can be used in a connection of, for example, a quartz pipe and a quartz pipe, or a quartz pipe 7 and a synthetic resin tube. The quartz pipe joint A has a joint body having a tapered pressing face a cylindrical sealing member 33 having a tapered receiving face 33, a lock ring which can deform to increase its diameter and deform to reduce its diameter and which can be fitted into an annular groove of the quartz pipe and a nut. When the lock ring fitted into the annular groove and the sealing member fitted into the quartz pipe are clamped by threadedly connecting the nut to the joint body, the sealing member is deformed to reduce its diameter by the function of the pressing face and the receiving face, so as to closely contact with the outer peripheral face of the quartz pipe, thereby exerting sealing properties. The lock ring engages with a groove wall of the annular groove to prevent the quartz pipe from slipping off from the joint.
