Title: Picture signal reproducing device
Inventor: OGURA TOKIHIKO
IPC: G11B20/02
Filed: 1989-07-25
Abstract: PURPOSE:To store a reproduced picture signal without being affected by a phase difference between a picture signal and a pilot signal caused in response to a reproduced track position by storing a reproduced picture signal according to a clock signal retarded in response to the reproduced track position. CONSTITUTION:A decoder 21a gives a voltage DV in response to a track number designated by a track designation signal P from a controller and the voltage is converted into an analog voltage VO by a D/A converter 21b. The voltage is amplified into a voltage V1 and fed to an anode terminal of a variable capacity CV connecting to a variable delay line 21d. The voltage VO is increased as the signal P designates more inward track. A voltage V2 (V2>V1) is given from a VCO of this circuit to a cathode terminal of the CV constituted the variable delay line 21b, and the voltage V2-V1 is decreased more as the signal P designates more inward track, resulting that the CV is increased to increase the delay of the variable delay line 21b. Moreover, the signal of the VCO of this circuit is given to a terminal 21e, a write clock signal of the memory is stepwise retarded in response to the position of the reproduction track and stored in the memory synchronously with the reproduction luminance signal. Through the constitution above, the original picture signal is accurately decoded.

Abstract: PURPOSE:To enable measurement of power loss in each phase with a standard capacitor (SC) connected to any one phase, by adding a variable inductance (VL) in series to a variable resistance (VR) and a variable capacitance (VC). CONSTITUTION:Electric current supplied from an AC power source 9 to a machine under test 10 forms a voltage VX1 with a phase leading that of the supplied voltage V1 by the loss angle of the machine 10 through a current transformer 12 and a mutual inductance 13. VR 14, VC 15 and VL 16 are adjusted so that the voltage VX1 and the voltage VS1 across a series circuit of VR 14, VC 15 and VL 16 are balanced. When balanced, from their values the power factor and also the power loss of the machine 10 is determined. The phase 120 deg. lagging the phase connected to SC 11 or the phase 120 deg. leading can be measured like the above only by connecting the current transformer 12 alternatively to each phase. Thus, a power loss measuring instrument using only one SC 11 and not requiring its connection change is available.
