IPC: F04B39/00
Filed: 1989-12-19
Abstract: PURPOSE:To more effectively prevent leakage of compressed air and to improve maintenance by mounting a plurality of piston rings to the outer peripheral part of a piston and forming a communicating passage having a given flow passage area in the piston or the piston ring. CONSTITUTION:A plurality of piston rings 7 and 8 to prevent leakage of compressed air are mounted to the outer peripheral part of a piston 2 in a state to make slide contact with a cylinder 3. A communicating passage 9 having a given flow passage area enough for introduction of gas compressed in the cylinder 3 to a space between the piston rings 7 and 8 is formed in the piston 2 or the piston rings 7 and 8. Through control of a difference between pressures exerted on the two surfaces of the piston rings 7 and 8, a force by means of which the piston rings are pressed against the inner peripheral surface of the cylinder 3 can be properly regulated. Leakage of compressed air can be prevented by sharing the work with the piston rings 7 and 8. This constitution improves compression efficiency and improve maintenance.

Inventor: OKUMA SHIGEO
IPC: G01M3/26
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To improve the leak diagnosis accuracy of an evaporating fuel treatment device. SOLUTION: This diagnosis device sets a decision level for diagnosing a leak on the basis of the first drive current of a motor operated pump 28 when air flows to a first passage 25 provided with a reference orifice 24 and compares the second drive current of the motor operated pump 28 when air is supplied to a canister 21, an evaporating fuel introducing passage 20 and a purge passage 22 from a second passage 27 bypassing the reference orifice 24 with the decision level to diagnose the presence or absence of the generation of the leak. In this case, when the first drive current is outside a reference level and the second drive current immediately after the switching operation of a selector valve 26 for switching the passage is outside a decision level set properly immediately after the switching operation, a leak diagnosis is stopped.  Thus, when the clogging or the stain of the reference orifice is generated or the switching operation of the selector valve 26 is imperfect, the leak diagnosis is stopped to prevent an erroneous diagnosis.

Title: Control device for dc brushless motor
Inventor: TOMIYAMA HIDEKI
IPC: H02P6/28
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To obtain a control device which prevents generation of a noise at a carrier frequency, by a method wherein the carrier frequency of a PWM control circuit is changed by a motor coil current so as to have a proper modulation width, an effective current is controlled and a rotational speed is changed. SOLUTION: When a current flows to a motor coil 6-1, a voltage at the (-) terminal of a comparator 11 exceeds a voltage at its (+) terminal. That is to say, the output of the comparator 11 becomes a level (L), a second NPN transistor 3-5 is turned off, a first NPN transistor 3-4 and a PNP transistor 5-1 in an switching control circuit are turned off, and the switching of the motor coil 6-1 is stopped. When the switching of the motor coil 6-1 is stopped, a voltage is not generated in a current detecting resistor 12, the voltage at the (-) terminal of the comparator 11 becomes lower than the voltage at its (+) terminal so as to become the same state as that immediately after a power supply is turned on, and a current flows to the motor coil 6-1.  In this manner, the electrification of the motor coil 6-1 is continued intermittently, and this operation is repeated so as to be set to a switching state.
