Title: Scroll fluid machine
Inventor: NAKAMURA SATOSHI
IPC: F04C18/02
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To increase the set volume ratio so as to prevent stress concentration on the tip of a scroll lap by allowing gas in a first space to flow to a discharging part through a sub passage after it is separated from the other space inner wall corresponding to the lap cut-off angle of one scroll. SOLUTION: A discharge port diameter is decreased and the set volume ratio is increased. That is, after a scroll lap forms a pair of minimum closed spaces 31, 32, compressed gas is allowed to flow to a discharging part 15 through a discharging chamber 35. In relation to this timing, the timing in which a lap outer wall surface 100 of a turning scroll traverses the contour line of the discharging port 15 is delayed. As a result, compressed gas in the first space 31 of a pair of minimum closed spaces 31, 32 is compressed until it is allowed to flow to the discharging port 15 through an opening part of the discharging port 15, and the set volume ratio is increased. Therefore, input of a compressor is reduced in the high pressure ratio operation, it is not necessary to make a shape of the cut-off of the scroll lap into an acute angle, and a problem of strength is dissolved.

IPC: G01R29/12
Filed: 1991-08-31
Abstract: PURPOSE:To measure the intensity of an electric field with high sensitivity by attaching a dielectric having a specific inductive capacity higher than that of an electrooptic crystal to the side face of the electrooptic crystal in an electric field impressing direction. CONSTITUTION:Rays of light from a light source are made incident to an electrooptic crystal 21 of lithium niobate, etc., from its surface in its z-axis direction through an optical fiber 22, lens 23, polarizer 24, and wave plate 25. The rays of light go out from the other side face of the crystal 21 after advancing through the crystal 21 and enter a photoreceptor through an analyzer 26, lens 27, and optical fiber 28. In this case, a dielectric 29, such as a rutile crystal, etc., having a specific inductive capacity higher than that of the crystal 21 is attached to the side face of the crystal 21 in a faced state in its X-axis direction and an electric field E to be measured is impressed upon the dielectric 29 and crystal 21 in the X-axis direction. As a result, the distribution of equipotential lines becomes sparse at the part of the dielectric 29 and relatively close in the crystal 21. Therefore, the detective sensitivity of the electric field can be increased, since a sufficiently large electric field intensity difference is produced in the crystal 21 in its X-axis direction and the optical change of the transmissive light further increases.
