Title: Electric power detecting device
Inventor: KAWAKAMI NORIKAZU
IPC: G01R21/06
Filed: 1985-02-13
Abstract: PURPOSE:To detect active power and reactive power without any ripple nor delay by detecting a system voltage and a system current and performing arithmetic processing in a power source association system. CONSTITUTION:The system voltage (v) and system current (i) are detected through a transformer or current transformer and passed through a delay circuit to obtain a voltage VLAG and iLAG which are 90 deg. out of phase. Then, the voltage (v) and current (i) are multiplied 10C and the voltage VLAG and current iLAG are multiplied 10D; and both outputs VA and VB are added 15A to obtain an output VP. The output VP contains only a DC component corresponding to the active power when the system voltage (v) and system current (i) are sine waves and no LPF is used, so there is no detection delay. Then, the voltage (v) and current iLAG are multiplied 10E and the voltage VLAG and current (i) are multiplied 10F. Then, the inversion output VC obtained by passing the output of the multiplier 10E through a phase inverter 14 and the output VD of the multiplier 10F are added 15B to obtain an output VQ. The output VQ contains only a DC component corresponding to reactive power when the system voltage (v) and system current (i) are sine waves and no LPF is used, so there is no detection delay.

Title: Thermal copying device
Inventor: FUJIMORI YOSHIHISA
IPC: G03B27/02
Filed: 1988-02-09
Abstract: PURPOSE:To make compensation for the influence on transfer density and to always obtain a uniform density image by arranging a reflecting material brought into contacted with a plane opposing to the transparent part material of exposure light sources or close to the plane and permitting the specific projection area on the transparent part material and reflecting again only such reflected light to the transparent part material. CONSTITUTION:The reflecting material 7a and 7b which permit the projection area of 50% or less of the effective copying region on the transparent part material are arranged so as to be brought into contact with or close to at least the light source planes opposing to the transparent part material. Most of the light of the exposure light sources is condensed in the direction of the transparent part material at the reflecting material 7a and 7b, and the light to be projected again to a copying original 5 among the light reflected by the non-image part of the copying original 5 is almost completely reduced. Therefore, most of the reflecting light caused by the non-image part of the copying original 5 is removed without reducing the exposure light source efficiency, and regardless of the occupation rate and position of the non-image part, the transcription density change is compensated. Thus, the uniform density image is always obtained.

Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To observe a vector amplitude value of a three-phase line current which is inputted to a three-phase induction motor by a DC current value in real time.

The product and sum of the square values are obtained by means of an adder 8 and a constant is multiplied thereto by means of a constant multiplier 9 and a square root is obtained by means of a root operator 10. As a result, a synthetic vector current value of the two-phase condition converted from the three-phase condition is obtained as a DC current value in real time.
