Title: Constant flow valve
Inventor: HIROTA HISATOSHI
IPC: F16K1/12
Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To reduce fluid passing sound by forming the outer peripheral surface of a valve element into shape narrowed toward the tip side so as to be loosely fitted into a valve seat hole from the upstream side, and forming a clearance between the inner peripheral surface of the valve seat hole and the outer peripheral surface of the valve element as a flow control passage.

The valve element 4 is arranged to be loosely fitted into a valve seat 2b from the upstream side. As a result, a fluid passes through a narrow annular clearance A formed between the outer peripheral surface 4a of the valve element 4 and the inner peripheral surface of a valve seat hole 2b. Fluid pressure in a line 1a is gradually heightened, and when the area of a flow control passage A is narrowed, flow becomes constant regardless of the grade of differential pressure in an area with fixed differential pressure or more, but even in this case, fluid passing sound is extremely low since the flow control passage A is formed in narrow annular shape.

Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To quickly complete communication by judging a state where a data amount to transmit is smaller than a prescribed quantity, and designating communication through a second communication system to a modem at the time of judging that the data quantity is smaller than the prescribed amount. SOLUTION: There can be two kinds of communication systems; a first communication system where a data communication speed itself is comparatively fast and a time for negotiation is comparatively long, and a second communication system where a data communication speed itself is comparatively slow but a time for negotiation is comparatively short. A mode judging part 11 judges a mode signal selected by a tuner 2 and gives the result to a communication system designating part 12. Thereby, in a state where the data amount to transmit is smaller than a prescribed amount, the second communication system where the data communication speed is slow but a time for pre-procedure is comparatively short. Consequently, at the time of transmitting a very small amount of data in advance, communication is quickly completed.
