Title: Linear actuator
Inventor: TAKETOMI MASAKI
IPC: H02K41/035
Filed: 1988-12-05
Abstract: PURPOSE:To enhance the conversion efficiency of electromechanical energy of a linear actuator by so providing a deflecting coil as to cross a magnetic flux, and reducing the width of the coil smaller than the longitudinal size of a permanent magnet. CONSTITUTION:Permanent magnets 3, 3 are so disposed on a center yoke 1 that different poles are opposed on the upper, lower surfaces and the inner surface of a side yoke 2 and different poles are alternately existed longitudinally. A pair of deflecting coils 3 having a coil width size smaller than the longitudinal size of the permanent magnet 3 are interposed longitudinally movably of the center yoke 1 and the side yoke 2 in a magnetic air gap 12 formed between the permanent magnets 3 any 3. Further, the deflecting coils 3 are supported by a movable member 4. Thus, when an AC current of a frequency synchronized with the rotating speed of a work is conducted in the deflecting coil, the movable member can be reciprocated by the frequency by the relationship to the magnetic flux by a permanent magnet, thereby enhancing an electromechanical energy conversion efficiency.

Title: Clock switching circuit
Inventor: SAGAWA YUICHIRO
IPC: G06F1/06
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To prevent an output waveform from becoming indeterminate after a system reset cancellation, and to prevent generation of a spike to output signals at the time of switching clock signals. SOLUTION: A D flip-flop 11 turns system reset signals RST to a reset input, and frequency-divides a master clock MCLK into two at the rise of the master clock MCLK, then outputs a clock CLK which is frequency-divided into two. The D flip-flop 12 turns the system reset signals RST to the rest input and latches and outputs clock changeover signals SEL at the rise of the output CLK of the D flip-flop 11. An inverter circuit 13, OR circuits 14 and 15 and an AND circuit 16 constitute a selector circuit, which outputs the master clock MCLK, when the output (a) of the D flip-flop 12 is high and the clock CLK frequency-divided into two, when it is low.
