Title: Variable capacity vane pump
Inventor: NAGATA SEIICHI
IPC: F04C14/22
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To reduce vibration and noise in a variable capacity vane pump. SOLUTION: A cam ring 70 is constructed to change opening positions of an inlet port 30 and a discharge port 40 in response to a rotating position of the cam ring 70. As the cam ring 70 rotates to a side of delaying timing when pre-compression and pre-decompression occur (leftward rotating direction), an end time of connecting the inlet port 30 with a pump room and a start time of connecting the discharge port 40 with the pump room are delayed while an end time of connecting the discharge port 40 with the pump room and a start time of connecting the inlet port 30 with the pump room are delayed.

Title: Hand piece for dental
Inventor: MATSUTANI KANJI
IPC: A61C1/08
Filed: 1988-11-11
Abstract: PURPOSE:To prevent the rotation of a holding body from being lowered by cooling water by connecting a second space, in which the cooling water leaks out, with the exhausting route of high pressure air by a connecting route and providing a seal member in the inner wheel of a bearing. CONSTITUTION:The cooling water to be supplied from a cooling water supply source is passed through a route 38 and injected into a flow-in hole 37. The most part of the injected cooling water is passed through a hole D for cooling water and emitted from a tip part. On the other hand, one part of the cooling water, which is emitted from the route 38 into the flow-in hole 37, goes to be a sprayed shape and leak into an upper space 28. This leaking cooling water is passed through the connecting route 38, sucked into an exhausting route 36 and exhausted to an external part together with exhausted air. Since a seal member 46 is fixed to an inner wheel 26a of a ball bearing 26, the cooling water to invade from an interval between the inner wheel 26a and an outer wheel 26c into a lower space 27 is flicked off by the centrifugal force of the seal member 46. One part of the high pressure air, which blows into the lower space 27, passes through the interval between the inner wheel 26a and outer wheel 26c of the ball bearing 26 and blows into the upper space 28.

Title: Internal heat insulation type gas pipe device and its corrosion prevention method
Inventor: ICHINOSE TOKUYUKI
IPC: F01D25/00
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To provide a convenient and inexpensive device without using an anticorrosive material by connecting a purge gas pipe which removes gas containing corrosive component which remains in a heat insulation material layer section of a pipe at least at one section on an outer face of the pipe. SOLUTION: Air pipes 5, 9 for purge are arranged from an air source 3 for control which has higher pressure than pressure of exhaust gas at a temperature below dew point of corrosive oxide in an exhaust gas pipe system having high temperature and high pressure. Purge gas 12 flows into a heat insulation material 10 of an external pipe 7 (exhaust gas pipe) from the air pipe 9 for purge from the time before corrosive oxide in exhaust gas when boiler load drops becomes dew point temperature till the time when exhaust gas does not flow after a boiler stops. Consequently, the corrosive oxide which remains in the heat insulation material 10 flows into exhaust gas flow passage, the corrosive oxide in the heat insulation material 10 part is purged, and a problem of corrosion of the external pipe 7 is eliminated.  Accordingly, it is unnecessary to use an expensive anticorrosive external pipe, and it is possible to realize an inexpensive internal heat insulation type gas pipe device.

Title: Swash plate structure of variable displacement swash plate type compressor
Inventor: KOBAYASHI HISAO
IPC: F04B27/08
Filed: 1989-11-02
Abstract: PURPOSE:To convert rotational motion of a swash plate into reciprocation so smoothly by forming an outer diameter of the swash plate into an ellipse setting the axial direction of tilt rocking to the breadth, and setting this breadth down to the sum of a distance between a turning axis and a center of shoe curvature and a radius of shoe curvature. CONSTITUTION:In a variable displacement swash plate type compressor, when a turning shaft 7 is rotated, a double-ended piston 6 reciprocates in both cylinder bores 5a, 5b in response to a tilt angle of a swash plate 13, whereby a refrigerant gas is compressed. This swash plate 13 is formed into an ellipse whose outer diameter sets the axial direction of tilt rocking down to breadth, and since this breadth is formed into length almost equivalent to the sum of a distance between an axis of the turning shaft 7 and a center of curvature of a shoe 15 and a radium of curvature of this shoe 15, even if a spherical recess 6a formed in the piston 6 is made deeper, there is no mutual interference when the piston 6 is moved and set up in a neutral position where the swash plate 13 and the piston 6 are liable to interfere with each other. Thus rotary motion of the swash plate can be converted into reciprocation of the piston so stably and smoothly.
