Title: Video output device, video output method and television receiver
Inventor: TOMIKAWA KAZUHIRO
IPC: H04N3/223
Filed: 2000-06-13
Abstract: PROBLEM TO BE SOLVED: To solve a problem that a conventional video output device has increased the cost because of addition of an analog circuit to a high voltage circuit resulting in increasing the number of components and increasing work processes at the assembling. SOLUTION: A DC-DC converter 80 converts a voltage level of a V-RAMP outputted from a chroma IC 20 and outputs the converted V-RAMP to an A/D port of a microcomputer 30. Thus, the microcomputer 30 detects that a peak voltage of the V-RAMP is fluctuated with a temperature change and outputs control data to set a peak voltage of a deflection drive signal so as to cancel the fluctuation component, and hence, the image screen size can be corrected by adjusting the deflection drive signal while reducing the cost.

Title: Reciprocal oscillation actuator and portable electronic equipment
Inventor: MARUO TSUNEHIRO
IPC: H02K33/06
Filed: 2000-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a reciprocal oscillation actuator of a small size, lightweight and high generating efficiency with a low power consumption. SOLUTION: This reciprocating oscillation actuator is equipped with an oscillator 23 with a magnet 25 supported by the movable end of a leaf spring 24 and is operated in such a manner that the oscillator 23 is driven at a specified angle θ resisting the spring force of the leaf spring 24 from an original position P1 to a rocking position P2 via the magnet 25 by energizing the drive coil L1 of a unidirectional drive magnetic circuit 27. Further, when the energization of the drive coil L1 is terminated, the oscillator 23 is automatically returned via the magnet 25 from the rocking position P2 to the original position P1 with the help of the spring force of the leaf spring 24.  Following the described operation, a counter electromotive force generated in a counter electromotive force generating coil of a magnetic circuit 33 for counter electromotive force generation, is energized to the drive coil L1 of the unidirectional drive magnetic circuit 27 by means of the magnet 25 during the automatic return of the oscillator 23 to the original position P1. Thus the rocking motion of the oscillator 23 is repeated.
