Title: Hose for joining pipe
Inventor: SHINADA RYOHEI
IPC: F16L33/24
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To join a joining hose without making a special joining structure on joined pipe to thereby facilitate the manufacturing of the hose and to reduce manufacturing cost by making annular projections on the inner surface of a joint part of a hose. SOLUTION: When the tip of a pipe 1 is pressed into a hose 2, the hose 2 is elastically expanded and presses the contact surface of the pipe 1 by elastic force. A plurality of annular projections 3 made on the contact surface of the hose 2 are pressed and flattened by the concentrated contact pressure because they have a small width to produce partial highly pressurized zones, whereby the contact surfaces can be sealed and the same effect as a labyrinth can be expected. If a hose band is used on the joint part of the hose 2, the contact pressure is increased to produce better sealing performance.

Title: Facsimile system and data transmission control method therefor
Inventor: HO GRANT I
IPC: G06F13/38
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a facsimile system with which a facsimile document is efficiently communicated without the occurrence of buffer underflow or buffer overflow. SOLUTION: In order to prevent the underflow that input to a buffer 4 can not follow up output from the buffer 4, a transmission pointer is forcedly waited at the place of a line end symbol on a present line and until at least two line end symbols are stored in the buffer 4, file bits are transmitted. In order to prevent the overflow that the output from the buffer 4 can not follow up the input to the buffer 4, when a write pointer gets too much close to the transmission pointer and the different points of continuous lines are sufficiently reduced, any line is selectively abandoned but when an allowable maximum buffer size is exceeded, the line is abandoned. At the time of scanning an image, a distance between the transmission pointer and the write pointer and the allowable maximum buffer size are gradually changed and the flushing of the buffer 4 is smoothly performed.
