Title: Flow rate control valve
Inventor: HATTORI HIROAKI
IPC: F16K31/06
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of leakage of an idle rotation speed control valve. SOLUTION: A movable valve seta 19 formed of an elastic substance is provided with an annular first seal part 19a, and an opening part 19b is opened to the inner periphery of the first seal part 19a. This movable valve seat 19 is formed such that an outer peripheral part is fixed and the inner peripheral side is bent in the direction of a plate thickness and by bringing the first seal part 19a into contact with a fixed valve seat 13, a first outflow passage 9 is shut off. A valve element 20 is formed such that a second seal part 20a protruded with it positioned facing the movable valve part 19 is brought into contact with the periphery of the opening part 19b, resulting in closing of an opening part 19b and the second seal part 20a parts from the movable valve seat 19, resulting in opening of the opening part 19b.  The movable valve seat 19 is pushed by the valve element 20 for adhesion to the fixed valve seat 13, whereby no gap is provided between the first seal part 19a and the fixed valve seat 13 and leakage of fluid from an inflow passage to the first outflow passage 9 is prevented from occurring.

Title: Driver for dc brushless motor
Inventor: ONISHI ICHIRO
IPC: F24F140/00
Filed: 1992-04-07
Abstract: PURPOSE:To alleviate stress in a component by predicting demagnetization of rotor magnet from the ratio between r.p.m. of motor and output voltage thereof and making a decision that the magnet is damagnetized when the predicted value drops below a predetermined value thereby limiting maximum r.p.m. CONSTITUTION:A pattern determining section 11 determines a 120 deg. conduction pattern output corresponding to current operational mode. A speed operating section 12 determines a motor speed. A comparing section 13 compares a speed command fed from a speed command section 21 with an actual speed to produce an error which is employed in a PI control section 14 for determining a duty. A duty ratio with respect to an r.p.m. omega is then operated at a ratio calculating section 15 and demagnetization of rotor magnet is predicted if thus operated ratio is lower than a predetermined value. At that time, a life prolonging operation mode for limiting maximum r.p.m. takes place and a corresponding chopping signal is outputted for controlling an inverter circuit 2. When a decision is made that the rotor magnet is not demagnetized, a chopping signal is outputted in normal operation mode and the inverter circuit 2 can be controlled.
