Title: Anti-lock brake controller
Inventor: HIGASHIMATA AKIRA
IPC: B60T8/66
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To conduct optimum anti-lock brake control while suppressing operating noise generated at an actuator in a low road surface friction coefficient condition. SOLUTION: A vehicle body speed gradient VXX and an estimated vehicle body speed VX are calculated based on the wheel speed detected value VWi (i=FL, FR and R) of three channels. A present estimated wheel cylinder pressure Pi for respective wheel cylinders is calculated based on a control signal condition against a previous actuator and present master cylinder pressure PMCF PMCR.  When it is in the initial condition of a moderate pressure intensifying mode and on a low friction coefficient road surface, by setting an initial moderate pressure intensifying amount ΔPZ0i , which is larger than on a high friction coefficient road surface, setting a moderate intensifying cycle longer than on the high friction coefficient road surface (steps S93b, S94a), and setting the next moderate pressure intensilying amount ΔPZi small (step S99), pressure intensifying amount per unit-hour is decreased to suppress pulsation generated at the actuator, thus it is possible to suppress operating noise.

Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To easily move into mesh both gears with each other by moving one gear in the diametrical direction and by meshing it with the other gear which is separated from an assembling surface. SOLUTION: While other shaft 6b of a second gear is supported by a chuck 8 or a second support, one shaft 6a is inserted in a gear hole 2. The chuck 8 is moved in an arrow K direction to move the second gear 6 in the diametrical direction so that the axial line of the shaft 6a is coincided with the axial line of the second shaft hole 4.

IPC: H03F1/30
Filed: 1987-10-26
Abstract: PURPOSE:To attain temperature characteristic compensation with high accuracy by providing 1st and 2nd variable current sources and a fluctuation detection means controlling a bias current outputted from the 1st variable current source and a bias current outputted form the 2nd variable current source. CONSTITUTION:Suppose that an emitter potential of a transistor(TR) Q3' rises due to the temperature drift of the TR Q3', an output of an operational amplifier OA is acted positively and a collector current of a TR Q4' is increased. Thus, the current injected to an FET Q1' is increased and the collector potential of the TR Q4' is decreased. The change is sent to the TR Q3' via a TR Q5' to decrease the emitter potential of the TR Q3'. Thus the temperature drift of the TR Q3' is compensated and always kept to zero. Then the temperature drift of TR Q3 is also compensated.

Title: Stepless one-way clutch
Inventor: OKADA WATARU
IPC: F16D41/02
Filed: 1994-10-06
Abstract: PURPOSE:To surely transmit torque while ensuring appropriate buffering effect by independently stopping or rotating an annular cam follower, concurrently contacting the action surface of a pair of coaxial idling eccentric cams, regardless of the rotation of a cam shaft by cam follower guide. CONSTITUTION:The torque of a cam shaft 6 is converted into the rectlinear motion of an annular cam follower 2 in a radial direction via a cam 8. When the rectlinear motion is limited by an idle tapered cam 10, surface pressure is generated between the annular cam follower 2 and the idle tapered cam 10 to transmit the torque of the cam shaft 6 to a rod 7. When an operating lever 20 is pulled down by about 90 deg. in a Q1 direction, a lever stay 23 is pulled out rightward and also tilted by the operation of a cam 16 serving also as a crescent. Accordingly, thrust in this direction is transmitted to the cam 10 via a stud 14 to detach a cam lining 10A, an action surface of the cam 10, from the action surface 2A of the annular cam follower 2. This can operate e.g. the reclining mechanism of the seat of an automobile.

Title: Method of controlling inverter device
Inventor: HASEGAWA MASAYASU
IPC: B66B1/30
Filed: 1987-10-27
Abstract: PURPOSE: To prevent low speed torque shortage at the time of hoisting and low speed over excitation at the time of lowering by selecting separate V/F patterns at the time of hoisting and lowering. CONSTITUTION: Hoisting and lowering are determined by the rotating direction of a three-phase induction motor 5. An ordinary normal-reverse rotation command is therefore used to distinguish hoisting and lowering. A hoisting command relay contact 7 is closed to perform hoisting. At this time, large starting torque is required, and it is necessary to compensate voltage drop by primary resistance r1 and primary leakage reactance x1 so as to select a pattern 1 of low speed with an increased V/F ratio. After stop, a lowering command relay contact 8 is closed to perform lowering. At this time, large starting torque is unrequired, and the rise of primary induced voltage E by regenerative energy is suppressed so as to select a pattern 2 lower in speed than the normal V/F pattern, with a lowered V/F ratio. Overexcitation of a motor can therefore be prevented.

Consequently, the press-contacting force to make the TL members abut and stabilize on the positioning members is positioning out of the moving routes of the TL members and a member transmitting the moving force, therefore, the whole device can be made small and thin by effectively utilizing the unused space in the device.
