IPC: F01L9/11
Filed: 1993-07-07
Abstract: PURPOSE:To reduce vibration in a valve which is opened and closed through the reciprocation of a valve plunger fitted in a cylinder hole and operated by hydraulic oil, by tapering the on-coming direction end part of the valve plunger so that the valve plunger is damped during on-coming operation. CONSTITUTION:A cam plunger 7 is reciprocated in association with the rotation of a cam 10a synchronized with the rotation of an engine, hydraulic oil in an oil chamber 11 which is pressurized during the reciprocation, is led into a small diameter hole 25 in a cylinder hole 25. When the hydraulic oil is led into a damper chamber 27 by way of a hole 26e, an oil sump chamber 26d, a small diameter part 26b and a large diameter part 26a of the valve plunger 26 are pressed. Accordingly, the valve plunger 26 is reciprocated, and a valve 2 is lifted from a valve seat 4, overcoming a spring 3. During reciprocation of the valve plunger 26, the valve plunger 26 is prevented from abruptly decreasing its speed since the front end part of the small diameter part is tapered so that the hydraulic oil can flow through the small diameter hole 25b when the small diameter part 26b is initially fitted into the small diameter hole 25b.

Title: Swash plate hydraulic rotary machine
Inventor: SAKAIRI TETSUYA
IPC: F03C1/253
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To suppress a pressure fluctuation occurring when a cylinder communicates with a discharge port. SOLUTION: A displacement piston 25 is situated in a piston containing groove 24 formed on the rear casing side. An oil chamber 26 communicating with a discharge port 20 is partitioned in the piston containing groove 24 by the displacement piston 25. A spring 29 is disposed between a displacement piston 25 and the piston containing groove 24 and the displacement piston 25 and a valve disc 18 are coupled together through a coupling pin 30. Thereby, when a pressure in a discharge port 20 is increased to a value higher than a reference pressure, the valve disc 18 is rotated as a result of the displacement piston 25 being displaced within the piston containing groove 24 against the spring force of a spring 29 and a timing at which communication with the discharge port 20 is executed by disconnecting communication with a suction port 19 by a cylinder is delayed.  This constitution suppresses a pressure fluctuation occurring when the cylinder communicates with the discharge port 20.

Filed: 1989-07-26
Abstract: PURPOSE:To reduce in thickness a well region of a MOS transistor without degrading performance by providing a high impurity concentration layer and preventing the well region from becoming of a low concentration even if the impurity is diffused in the well region. CONSTITUTION:A P<+> type region 20 having high impurity concentration is formed in a P-type well region 5 near a boundary between the region 5, an N<+> type buried layer 2b and an N-type well region 7. An N<+> type buried layer 2a is formed in a region A of a bipolar transistor Tr 100 on a substrate 1, and a buried layer 2b is formed in a CMOS region. A P-type buried layer 3 to become an isolating region of an NPN type Tr 100 is so formed as to surround the layer 2a. Thereafter, an N-type epitaxial layer 4 is so formed as to cover the layers 2a, 2b, 3. Then, since there is the high concentration layer even if the N-type impurity is diffused from the layers 2a, 2b, 3 in the regions 3, 7 by heat treating, it can prevent the P-type impurity of the regions 5, 7 from becoming a low concentration. Thus, the region 7 can be reduced in thickness without degrading performance of the Tr 100.

Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent the impedance characteristic of reception termination from being affected by the frequency characteristic of output impedance in a constant current source. SOLUTION: In the case of supplying ECL current output from transmission ICI to reception IC2 through a transmission line 3 having specified characteristic impedance Z0, a resistor 21 is connected to a connection terminal B with the transmission line 3 is reception IC2.
