Filed: 1991-08-21
Abstract: PURPOSE:To convert a time axis with one memory system by sharing a luminance signal and a line sequential chrominance signal to a field memory for each 1H and selecting the luminance signal or the chrominance signal alter nately based on a write clock. CONSTITUTION:A luminance signal and a chrominance signal are read alternately for each 1H based on a clock from A, B channel memories 13-18. The output is selected alternately by selectors 23, 24 and the selected output is outputted. The data of the luminance signal becomes a reproduced Y signal via a dropout compensation circuit. A chrominance signal data is inputted to a sequence replacement circuit, the data sequence is replaced and a line sequential chrominance signal series is obtained. The output of the sequence replacement circuit is a signal of a data series via a dropout compensation circuit. Then the line sequential chrominance signal is interpolated via a vertical filter and a signal PB and a reproduced PB are obtained. The reproduced Y signal and the signal PB and the reproduced PB are converted respectively into analog signals by D/A converters 25, 26 and the result is outputted. Thus, the circuit scale is reduced.

Abstract: PURPOSE:To perform a rapid reaching of an injection nozzle to its target position, restrict a heat generation at a motor and improve durability of a hot water feeder by a method wherein a feed-forward control and a feed-back control are combined to each other. CONSTITUTION:At a control part 30, the number of output value of a required rate of combustion calorie of a burner is calculated in reference to a set hot water feeding-out temperature and a feeding water flow rate. A feed-forward control is carried out up to an advancing position (the number of steps of a stepping motor 12) of the nozzle 11 corresponding to the calculated number of outputs in reference to a relation between the number of outputs and the injection nozzle position. This control is carried out by outputting the stepping motor 12 up to the calculated number of steps. Then, the actual fed-out hot water temperature and a set outputted hot water temperature are compared to each other at the control part 30 and then a feed-back control is carried out at a control value corresponding to the difference. This control is carried out by intermittently outputting the driving pulse of the stepping motor with a width variation outputting system.

Title: Stator core for linear motor
Inventor: YAGISAWA TAKESHI
IPC: H02K1/18
Filed: 1989-08-17
Abstract: PURPOSE:To reduce vibration and noise due to magnetic attraction by laminating punched core sections, while shifting slightly in the direction of lamination, such that a stair type cross section is provided at the butting section. CONSTITUTION:Five types of core boards 6-10 punched from an electromagnetic steel plate are laminated, while shifting the cutting position slightly at the yoke section, such that a stair type end section is provided. The core components are butted and jointed to construct a stator core, where the position of a gap 5 to be formed at the butting section is shifted layer by layer in the cross section at the yoke section. Flux in the punched core board 6a does not flow through the gap 5, as shown by arrows, but passes through the punched core boards 7, 10 laminated vertically and returns to the original layer, i.e., a punched core board 6b. Since the flux does not flows through the gap, no magnetic pole is produced. Consequently, inter-pole magnetic attraction is not produced and thereby vibration and noise can be suppressed.
