Abstract: PROBLEM TO BE SOLVED: To cope with power measurement in various kinds of circuit systems including a three-phase four-line circuit with one model by providing a plurality of voltage and current input means of a three-phase or single-phase electric circuit and a means for setting a circuit system. SOLUTION: The multiple-circuit-type wattmeter is provided with, for example, voltage input means 9 and 10, power input means 11 and 12, and a circuit system setting means 13 for setting the circuit system of an electric circuit being measured by three-phase three-wire, single-phase three-wire, single-phase two-wire, three-phase four-wire, or the like. And, when the circuit system is set to three-phase four-wire, both the voltage input means 9 and 10 and voltage input means 11 and 12 become the input wire of single-phase three-wire, add each phase power for two circuits of the single-phase three-wire by a power measurement means 14, and measures the power of the three-phase four-wire. An watthour can also be metered by the similar method. The watthour can be grasped individually for each phase.  Measurement can be made by performing each specific setting for the cases of single-phase three-wire, single-phase two- wire, and three-phase three-wire systems.

Title: Transmission system for television signal
Inventor: KAGEYAMA MASAHIRO
IPC: H04N11/14
Filed: 1991-09-25
Abstract: PURPOSE:To attain the transmission giving less disturbance to an existing receiver while keeping compatibility with an existing television system and separating a luminance signal and a chrominance signal in an excellent way without being affected from the transmission line by applying time division multiplexing to specific main and a auxiliary signals respectively and sending the result. CONSTITUTION:Color difference signals I,Q are subject to orthogonal modulation by using a subcarrier fsc' having a spectrum at a location symmetric to a chrominance subcarrier with respect to a 'time-vertical' frequency region to obtain an auxiliary signal H. Then a main signal resulting from frequency-multiplexing the luminance signal and the chrominance signal is allocated in the center of the screen (main part) and an auxiliary signal H resulting from frequency-converting the chrominance signal is allocated to a position symmetrical to the chrominance signal with respect to a 'time-vertical' frequency region at an upper and lower parts of the screen (mask part) and they are sent. A receiver side reproduces the chrominance signal from the auxiliary signal H and the reproduction chrominance signal is reduced from the main signal to reproduce the luminance signal. Thus, since the transmission characteristic of the main signal and the auxiliary signal H is balanced, the luminance signal and the chrominance signal are separated without crosstalk independently of a still or a moving picture.

Title: Silver halide photographic sensitive material for direct positive
Inventor: UESAWA YUTAKA
IPC: G03C1/79
Filed: 1985-10-31
Abstract: PURPOSE:To eliminate the influence of the fluctuation in the moisture content of a paper substrate by incorporating an alkyl acrylate polymer latex having compatibility with a gelatin at 10-50wt% by the weight of the gelatin binder into a silver halide emulsion and incorporating a polyhydric alcohol at 3-30wt% by the weight of the gelatin binder therein. CONSTITUTION:The alkyl acrylate polymer latex having compatibility with the gelatin is incorporated at 10-50wt% by the weight of the gelatin binder into the silver halide emulsion for direct positive and the polyhydric alcohol is incorporated at 3-30wt% by the weight of the gelatin binder into said emul sion. Stability with lapse of time is not improved if at least either of the alkyl acrylate polymer latex and polyhydric alcohol is below the above-mentioned content range. Low sensitivity and soft gradation are caused and the photo graphic performance is poor if the amt. of the alkyl acrylate polymer latex to be used exceeds the above-mentioned range. On the other hand, the film surface of the photosensitive material absorbs moisture and the adhesion trouble such as sticking of the films to each other during storage arises if the amt. of the polyhydric alcohol to be used exceeds the above-mentioned range.

Title: Blocking circuit for picture signal
Inventor: YONEMITSU JUN
IPC: H04N19/00
Filed: 1987-09-30
Abstract: PURPOSE:To excellently interpolate the picture element data of a block, whose error cannot be corrected by forming the two blocks with the picture element data at every prescribed interval included in the area with the double range of the block, and separately positioning the picture element data of the two blocks at the time of transmission. CONSTITUTION:In the two areas to respectively belong to two continuous frames and to occupy the same spatial position, the two blocks are formed by white and black dots positioned in a five-spot lattice-shaped die. A blocking circuit 3 is composed, for example, to possess two two-frame memories, and the data are alternately written and read in the two memories. The two blocks are recorded at separate positions at the time of recording, and a burst error prevents the both from being the error data together. In the reproduced data, when one of the data block, for example those of the white dots, becomes the error data, since the correct data of the black dots of the other block is circumferentially positioned, the error data can be interpolated in the frame to a smoothing/interpolating circuit 38 by interpolating the data of the central white dots using, for example, the mean value of the circumferential data.
