Title: Pipe joint
Inventor: SHIMADA HARUMI
IPC: F16L33/22
Filed: 1990-06-07
Abstract: PURPOSE:To obtain an easily producible locking structure for an insert by providing a locking member having a shape for locking on the tapered part of a socket on the outside of the insert. CONSTITUTION:A locking member 9 is formed into a shape locking on the tapered part of a socket 3, and protrusively provided on the outside of an insert 4 to function for locking the insert 4. When the insert 4 moves a little in the direction of its slipping out, the locking member 9 moves together with the insert 4 to abut on the inner end of a collet 5. Thus, when a pipe 6 moves in the direction of its slipping out, the locking member 9 begins to wholly move in the same direction. When a little movement occurs, the collet 5 is influenced by the tapered shape of the socket 3 to tightly fasten the pipe 6, which does not move beyond a fixed length in the direction of its slipping out to be prevented from slipping out. The locking member 9 also locks on the tapered part of the socket 3 at the sams time not to move beyond a fixed length toward an inserting port. Thus a pipe joint having a locking mechanism for the insert 4 can be easily produced.

Title: Method for producing semiconducting single crystal
Inventor: SAISHOJI TOSHIAKI
IPC: C30B15/00
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a semiconducting single crystal, capable of preventing the occurrence of transition in a body even into the case omitting the tail formation in the production of the semiconducting crystal by CZ-method. SOLUTION: Directly after the termination of the body formation of a single crystal 8, the pulling up speed is increased to separate the single crystal 8 from a melt 2, and subsequently the pulling up speed of the single crystal 8 is controlled to anneal it in an arbitrary crystallization temperature region. Thus, a single crystal ingot having a separated end of concave or corrugated surface is obtained. Concretely, the single crystal 8 is cooled in such a condition that the cooling speed at the area close to the separated end 8a is <=35 deg.C/min between the molting point and 1000 deg.C, or the single crystal 8 is held for >=30min in such a condition that the temperature in the area near the separated end surface 8a is 1250-1000 deg.C.  The introduction of transition from the separated end surface 8a into the body can be prevented by the annealing, and at the same time the productivity of the semiconducting single crystal is improved.
