Title: Motor stator and its formation
Inventor: CHIN RIRYU
IPC: H02K15/02
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a motor stator which is easy to manufacture and allows the enhancement of the efficiency of the motor and increase in a non-defect rate. SOLUTION: This motor stator 1 is formed by integrally molding hollow toothed blades of silicon steel by press working. The toothed blade has four short projected teeth 11 and four long projected teeth, and the long projected teeth and the short projected teeth 11 are coupled alternately with the periphery of a first circular section 13 in the circumferential direction. The long projected teeth are bent, and the posts 15 perpendicularly coupled with the first circular section 13 and the lower projected teeth 14, coupled with the lower end of the posts 15 parallel with the first circular section 13, are integrally molded.  Since the stator is formed by press working, the upper projected teeth 11 and the lower projected teeth 14 can be aligned precisely, so that magnetic poles are at an angle such that they complement each other in the circumferential direction, by press mold designing. Therefore, a motor stator with magnetic poles positioned precisely can by formed by a simple work, and the stability of the motor can be enhanced.

Title: Rotor
Inventor: TAMURA SHINYA
IPC: H02K1/27
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable and thermally strong rotor employing a ring magnet. SOLUTION: An Nd based ring magnet 1 shrinks thermally to apply a stress to a laminate yoke 3 but since a substantially T-shaped pole tooth part 4 is bonded only at the central groove part 5 and not bonded at the arcuate end part, it can flex freely in the inner circumferential direction to absorb stress. Even if an undue stress is applied thermally to the ring magnet, the stress can be absorbed by the features of the bonded part and the substantially T-shaped pole tooth part and thereby the ring magnet can be protected against damage.

Title: Spread spectrum communication equipment
Inventor: KATOU ICHIROU
IPC: H04W92/00
Filed: 1987-06-09
Abstract: PURPOSE:To eliminate a near/remote problem such as increase in noise power depending on the distance between communication equipments by controlling the amplifier gain and the transmission power of a reception system to a proper value in response to the strength of a received signal. CONSTITUTION:When no communication is implemented with an opposite station, an AGC voltage generating circuit 19 controls variable amplifiers 4, 13 to a maximum gain. When an opposite station signal corresponding to the reception channel is given to an antenna 1, after the phase synchronization of the spread code for the modulation and demodulation with the opposite station is established, the reception output signal of the amplifier 4 is increased. Thus, the circuit 19 controls the gain of the amplifier 4 so that the output signal becomes a proper value. Simultaneously, the gain of the amplifier 13 of the transmission system is lowered so that the electric field strength in the opposite side antenna is a proper value. On the other hand, in case of a call, since the amplifier 13 has a maximum gain in the initial state, the electric field strength in the opposite antenna is inadequately large, and the input signal to the circuit 19 is increased by the reply of the opposite party, resulting that the gain of the amplifier 13 is controlled automatically in a way that the electric field strength of the opposite antenna is a proper value.

Title: Controlling method for cooling device to prevent from clogging
Inventor: TAKAMATSU EIJI
IPC: F25B1/00
Filed: 1991-06-14
Abstract: PURPOSE:To prevent clogging induced by dust and dirt by driving a fan reversely for a specified time when the wind velocity of cooling air of a condenser or its air capacity fails to exceed specified value in a cooling device for automatic vending machines. CONSTITUTION:A fan of a cooling device which cools a condenser by means of the fan is so arranged that it may rotate reversely. At first, a predetermined value by a window power or air capacity setting means A is compared with a detected value of a wind power or air capacity detection means B by means of an air capacity drop decision means C. When the wind power or air capacity is decided as lower than a specified value, a normal rotation/reverse rotation decision means D outputs a signal, which rotates the fan reversely, to a normal rotation/reverse rotation output means E. The time for reverse rotation is preset by a reverse rotation capability time zone setting means F. The lapse of the specified time is decided by a timer means G so as to return the operation to normal rotation. It is also acceptable that the fan be rotated reversely for every specified time zone or specified operation accumulation time without depending on the drop in the wind power.
