Title: Lighting device for fluorescent lamp
Inventor: SATO MASARU
IPC: H05B41/24
Filed: 1991-11-28
Abstract: PURPOSE:To eliminate the interference of lighting frequencies so as to prevent erroneous operation of a remote control device by responding an external synchronous signal so as to determine the timing of stagger lighting when a plurality of fluorescent lamps are turned on, and by energizing a lighting circuit with this timing. CONSTITUTION:In a synchronous lighting circuit, the output side of an OR circuit 24 is connected to the base of a transistor 25 whose collector is connected to a node D f an inverter 5 through nodes S, P, N, K, E, and the emitter thereof is connected to a terminal 28a of an output terminal assembly 28 through a resistor 26. When an output signal is transmitted from the thus constituted circuit 24, the transistor 25 is energized so that a signal received from an input terminal 27 is delivered from the terminal assembly 28. Accordingly, the rate of the transmission of the input electrical signal to the terminal assembly 28 through a pohotocoupler 15, AND circuits 22, 23 and the circuit 24 becomes higher so as to enable high frequency lighting fluorescent lamps 2A to 2C may be synchronously turned on. That is, the turn-on frequencies of the fluorescent lamps 2A to 2C becomes equal to one other.

Filed: 1989-12-28
Abstract: PURPOSE:To lower resistance of a gate electrode and source/drain diffusion regions to accelerate operation of a CMOS transistor by constituting the gate electrode of a MOS transistor of first high melting point metal or its metal compound and constituting a source/drain electrode of second high melting point metal or its metal compound.

Title: Stepping motor
Inventor: NARISAWA SADAYOSHI
IPC: H02K37/14
Filed: 1991-11-30
Abstract: PURPOSE:To obtain a stepping motor having less vibrations and noises by rotating a rotor magnet by applying pulses to the coreless coils of the stator in which a plurality of coreless coils having no yolks are arranged in parallel in a ring shape. CONSTITUTION:A stator 12 comprises the main bodies 22a and 22b which are separable into two in the axial direction; a plurality of first coreless coils 24 and second coreless coil 26 arranged in parallel in a ring shape on the outer circumference of the main bodies. Then, when pulses of a given cycle are applied to an odd numbered coreless coil 24 and an even numbered coreless coil 26, the magnetic poles having inverted polarities are generated in a given cycle because the coreless coils 24 and 26 have different winding directions. Further, the polarities of the magnetic poles generated by the adjacent coreless coils 24 and 26 are the inverted polarities. Thus, for the stator 12, N pole and S pole are formed by the coreless coils at equal intervals in the circumferential direction. The magnetic poles are inverted in a given cycle to cause the rotor magnet 14 to rotate, but there are no cores in the coreless coils, hence making it possible to reduce the generation of vibrations and noises.
