A fluid coupling for a corrugated pipe, comprising a coupling body having a large-diameter portion and a small-diameter portion through which the corrugated pipe can be passed, metallic seal means arranged at the small-diameter portion, for sealing an end portion of a corrugated pipe pressed against the same, a ring-shaped engaging member disposed in the large-diameter portion and having its inside diameter reducible to a size smaller than the diameter of the top of corrugation of the corrugated pipe, and retaining means having an outside diameter small enough to be inserted into the small-diameter portion, an inside diameter large enough to be penetrated by the corrugated pipe, and a first end portion capable of engaging the engaging member, the retaining means being adapted to press the end portion of the corrugated pipe against the seal means, while transferring the elastic member from the large-diameter portion to the small-diameter portion, thereby holding the engaging member in a predetermined axial position such that the engaging member is located in a root portion of the corrugated pipe.
摘要:
A pipe coupling for the union of a corrugated pipe therewith is formed of a pipe coupling proper and a lock cylinder for fixing a corrugated pipe. The lock cylinder is helically joined to the inner surface of the leading part of the pipe coupling proper and fixes the corrugated pipe by rotationally closing the lock cylinder helically tacked to the pipe coupling proper, and at the same time seals the pipe coupling proper by pressing the leading terminal part of the lock cylinder against a seal ring attached fast to the interior of the pipe coupling proper, enabling the corrugated pipe to be infallibly locked and sealed owing to the provision of a spacer adapted to preset and keep a closing distance for the lock cylinder. The spacer is detachably attached to the periphery of the pipe coupling proper.

A socket of a tube coupler is manufactured in the following steps: A rectangular steel plate is formed with pin-guiding lock grooves which are arranged at equal longitudinal intervals after the plate has been wound. The plate is wound as a single layer along the longitudinal direction thereof to form a tubular body. When the tubular body is used as a connector between a socket main cylinder and a socket adapter and when the socket adapter is fitted closely in one end portion of the tubular body, the other end portion of the tubular body is fixedly fitted in the free end portion of the socket adapter. Thereafter, the pins are fixed to the outer periphery of the socket main cylinder, through the respective lock grooves, so that a socket is manufactured. When, on the other hand, the tubular member is used as a socket main cylinder, the lock grooves are formed so that one end of each thereof opens at one end of the socket main cylinder, and a socket adapter is connected to the other end of the socket main cylinder to form a socket. A plug having the pins is guided by the lock grooves to be inserted into the socket.

A non-aqueous electrolyte secondary battery includes an electrode body including a positive electrode and a negative electrode superimposed upon each other with a separator interposed therebetween. The negative electrode is superimposed upon the positive electrode in a state where a negative electrode active material layer, except the part on a proximal end part of a negative electrode tab, is positioned inside an outer edge of a positive electrode active material layer of the positive electrode. A width H1 of the negative electrode active material layer including the part on the proximal end part of the negative electrode tab, width H2 of the negative electrode active material layer or negative electrode current collector at a part other than the negative electrode tab, and width H3 of the positive electrode active material layer are formed to satisfy the relationships of H2

A processing method for a wafer having a device area where a plurality of devices are formed on the front side of the wafer and a peripheral marginal area surrounding the device area. The processing method includes a reinforcing plate forming step of applying a heat-resistant bond to the front side of the wafer and solidifying the heat-resistant bond to thereby form a reinforcing plate from only the heat-resistant bond, a back grinding step of holding the reinforcing plate on a chuck table and grinding the back side of the wafer in the device area to thereby form a circular recess in the device area and leave an annular reinforcing portion in the peripheral marginal area, a through electrode forming step of forming a through electrode connected to an electrode of each device formed on the front side of the wafer, from the back side of the wafer fixed to the reinforcing plate, and a reinforcing plate removing step of supplying a solvent for dissolving the heat-resistant bond to the reinforcing plate, thereby removing the reinforcing plate.
