Title: Manufacture of molded coil
Inventor: MIZUTANI YUUJI
IPC: H02K15/12
Filed: 1984-06-22
Abstract: PURPOSE:To improve the finishing external appearance by molding by two stages for switching molding and pouring pressure from low to high pressure when disposing a stator in a mold and integrally molding the resin, and eliminating to expose the end of a winding with the resin surface after molding. CONSTITUTION:When a stator core 1 in which a stator winding is mounted is disposed in a mold having a lower die 2 and an upper die 4, thermosetting resin 6 is poured to be integrally molded, the resin 6 is initially poured under low pressure C, the pouring pressure is switched from the pressure C to a high pressure D immediately before filling completely the resin 6 in the mold, thereby completing the molding of the coil. Thus, since the coil end of the stator winding is not pressed toward the inner peripheral direction of the stator, the end of the winding is not exposed on the surface of the resin 6.

Abstract: PURPOSE:To reduce a reversible change which is generated by the irradiation of light and thermal annealing by specifying the sodium concentration of an active semiconductor layer to the minimum concentration region and also specify ing a recombination center density. CONSTITUTION:The remaining sodium inside a quartz jig and the like is degassed by holding a quartz substrate 10 in a reactor l, mixing hydrogen chloride 99.99% or higher purity in the reactor 1 land heating them at 1150 deg.C.The sodium concentration is reduced until it becomes 5X10<18>cm<-3> to 1X10<14>cm<-3> in the minimum concentration region.

Title: Rear wheel steering angle regulator
Inventor: WATANABE RETSUO
IPC: B62D7/14
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To prevent the sudden change of a rear wheel steering angle even with the generation of runaway of a controller at the time of large steering angle steering by moving a locking member with a locking groove or a locking hole formed to insert the tip of a lock pin, by an electric motor rotated synchronously with a front wheel steering angle. SOLUTION: A locking groove 107 is formed in a locking plate 104, and the tip of a lock pin 108 fixed to a rod 2 is inserted therein. When a stepping motor 101 is rotated, the lock pin 108 is moved in the axial direction of the rod 2. When the rod 2 is controlled normally, the locking groove 107 moves along with the lock pin 108 so as not to impede the movement of the rod 2, but in case of a controller outputting a signal unsuited to a front wheel steering state because of mulfunction, the synchronization of the rod 2 and locking plate 104 collapses due to runaway of the motor or the like, and the lock pin 108 can move only in a range of a clearance in the locking groove 107 even if the movement of the rod 2 becomes fast. No sudden change of a rear wheel steering angle is therefore generated.
