Title: Commutator motor
Inventor: NAKAMURA YUICHI
IPC: H02K23/66
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To provide motor characteristics for preventing spark between a brush and a commutator and having reduction effect of third harmonic current components even if an AC sine-wave voltage is applied, in the stator magnetic structure of a commutator motor. SOLUTION: A stator core is split to an outer magnetic circuit 2a and an inner magnetic circuit 3. Anisotropic silicon steel plate is used as the circuit 3, and its axis of easy magnetization is fixed to fix the direction of flowing a magnetic flux. The flowing direction of the flux is fixed to alleviate the local saturation of the core to make the flow of the flux uniform, thereby preventing the variation of the neutral point of the armature. When an AC voltage is applied, the third harmonic wave current due to the local saturation of the flux can be reduced.

Title: Drive circuit for field effect transistor
Inventor: ITO KAZUYUKI
IPC: H03K17/04
Filed: 1984-09-12
Abstract: PURPOSE:To attain a compact and light-weight FET drive circuit having high efficiency, high reliability and high performance, by providing a switch circuit and a capacitor to a winding at the signal source side of a transformer in order to ensure high-speed and assumed ON/OFF operations of the FET. CONSTITUTION:When a drive pulse is applied to a switch circuit 2 from a signal source 1 through a switch element Q2, both elements Q3 and Q4 are turned on and off alternately. Then a capacitor C1 is charged with the power supply voltage V2 when the Q4 and Q3 are turned on and off respectively. At the same time, the pulse voltage V2' corresponding to a winding ratio is transmitted to a winding N2 from a winding N1. Thus an FETQ1 is turned on. Then the electric charge stored at the capacitor C1 is discharged through the Q3 when the Q4 and Q3 are turned off and on respectively. Thus the voltage Vn2 corre sponding to a winding ratio is transmitted to the N2 from the N1. This voltage Vn2 has the polarity opposite to the gate-source polarity of the Q1 and therefore the Q1 is turned off. Here the voltage Vn2 is set at a fixed level in an ON mode of the Q3 since the stored electric charge of the C1 is set at a fixed level dependent on the voltage V2 when the Q4 is kept ON. Thus the Q1 is turned off assuredly and at a high speed despite the narrow width of the drive pulse.

This prevents a surface oxide film generated when using a III-V compound semiconductor substrate from being generated, and the group III element nitride semiconductor having larger band gap than that of the semiconductor itself is used as the insulator film. When coating it with the group III element nitride after the semiconductor is epitaxially grown, the group III material of the III-V compound semiconductors, the group V material of the III-V compound semiconductors, the group III material of the group III element nitrides and a nitrogen material are sequentially supplied.

Filed: 1996-07-01
Abstract: PROBLEM TO BE SOLVED: To decide an optimum motion vector by using a spatial correlation between the picture elements of block signals, which is compensated with a timewise correlation between frames. SOLUTION: An error function between picture element data on the search block of the present frame and picture element data on respective candidate blocks of candidate block forming parts 24-1 to 24-N is calculated and an error function value on the candidate block is obtained in block matching parts 26-1 to 26-N.
