Title: Stator structure for rotation sensor
Inventor: OSHITA KOZO
IPC: G01P3/488
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To obtain a stator structure by which a magnetic body for magnetic-flux correction can be placed and held easily and surely by forming a holding hole in a magnetic-pole cover and attaching the magnetic body to it. SOLUTION: A plurality of cover bodies 3 which are composed of an insulating material, which are arc-shaped and which are in a segment shape are placed, in units of prescribed angles, on a ring-shaped stator 1 on which a plurality of magnetic poles 2 are formed so as to protrude. The ring-shaped stator 1 at 360 deg. is covered wholly with the over bodies 3. In addition, in every magnetic pole cover 4 on every magnetic pole 2, a flange part 4a is formed at its tip so as to prevent every stator winding 6 from overflowing to the outside. A pair of holding holes 11 are formed integrally on both sides of every flange part 4a along the axial direction of the ring-shaped stator 1, and magnetic bodies 10 such as pins or the like for magnetic-flux correction can be inserted.  Consequently, when a magnetic flux from every magnetic pole 2 is corrected, the magnetic bodies 10 are inserted into the respective holding holes 11, and a generated magnetic flux is set at a prescribed magnetic flux intensity. When the holding holes 11 are formed in this manner, the interference of every stator winding 6 with the magnetic bodies 10 can be prevented even when the magnetic bodies 10 are inserted via respective slots, and the magnetic bodies 10 can be placed easily and surely.

Title: Torque detector
Inventor: AOKI HIROYUKI
IPC: H02K11/00
Filed: 1986-02-04
Abstract: PURPOSE:To accurately detect a torque acting on a shaft to be measured, by making a local anisotropy of magnetic permeability in the surface of the shaft being measured isotropic by a magnetic field to eliminate variations in the output due to the rotation of the shaft. CONSTITUTION:A yoke 4 comprising an exciting coil 2 and a detection coil 3 is made to approach a hardened or annealed shaft 1 of a magnetic body to form a magnetic circuit with a magnetic flux of the coil 2 to detect a magnetostrictive component passing through the shaft 1 with the coil 3. When clockwise or counterclockwise torque T is applied on the shaft 1, the magnetic permeability increases or decreases by +sigma or -sigma as inclined by 45 deg. to the shaft and the sum thereof is captured as output. After the shaft 1 is inserted into a solenoid coil, an alternating magnetic field is applied thereto and then, the voltage is lowered to 0. This can turn a local anisotropy of the magnetic permeability in the surface of the shaft isotropic, which eliminate output variations to stabilize it, thereby enabling accurate detection of a torque acting on the shaft.

Title: Ignition timing controller for internal-combustion engine
Inventor: TATE TAKAO
IPC: F02P5/15
Filed: 1983-02-14
Abstract: PURPOSE:To prevent engine stop by controlling the ignition timing in accordance to engine speed and load, by igniting with predetermined lead angle upon detection of deceleration thereby preventing dropping of revolutions immediately after reset of idling. CONSTITUTION:When a throttle valve 8 is fully closed and the car speed is below referential level, a microcomputor 28 will decide it to be an idle state and to read out the idle ignition lead angle stored in ROM. Then predetermined angle is subtracted from basic ignition lead angle calculated from every predetermined time or crank angle to perform processing for approaching gradually to idle ignition lead angle and return. Thereafter the basic ignition lead angle is corrected on the basis of signals to be provided from various sensors to obtain the ignition lead angle which is used together with ignition angle calculated to approach gradually to the idle ignition lead angle to control on-off period of ignitior and the ignition timing. In such a manner, ignition lead angle from deceleration to immediately after reset of idling is led when compared with conventional one to prevent drop of rotation upon unclutching immediately before stoppage.
