Title: Correcting circuit of phase of chrominance signal
Inventor: FUNASHIRO HIDEKAZU
IPC: H04N9/455
Filed: 1983-06-15
Abstract: PURPOSE:To attain correction of discontinuity of a phase of a chrominance signal by detecting the phase of a color burst signal at every other horizontal period and forming a control signal in response to the phase to apply phase control to the chrominance signal. CONSTITUTION:The color burst signal and a horizontal synchronizing signal (a) separated from a reproduced video signal are applied respectively to input terminals 1, 10. The color burst signal is applied to a color burst phase detecting circuit 2 to generate a pulse signal (b) constituting of the 1st positive pulse and the 2nd negative pulse in response to the phase. Further, a gate signal (e) is formed from the signal (a) by an oscillating circuit 11 and a frequency dividing circuit 12. Then an FF circuit 13 is reset in the period A where the 1st track is scanned for reproduction, no chrominance signal is subject to delay, the circuit 13 is set in the period B entering the 2nd track and the chrominance signal is delayed by 1H. The discontinuous point of the chrominance signal is detected by utilizing the relation of phase between the signals (b) and (e) at each change of track, the amount of delay of the chrominance signal is changed and the discontinuity of phase is eliminated.

IPC: H01F27/02
Filed: 1980-08-04
Abstract: PURPOSE:To conduct excellent oil filling work by a method wherein the inside of a tank, a side wall thereof is formed by a corrugated radiation plate with a finny projecting section, of the oil-filled electrical machinery and apparatus is filled with insulating oil and hermetically sealed, and the voluminal change of insulating oil is absorbed by utilizing the elastic deformation of the projecting section. CONSTITUTION:The corrugated radiation plate 1 shaping the side wall of the tank, an upper frame, a bottom plate 8 and a cover 9 are all constituted through welding in the tank 5 housing a content 6. The inside of the tank 5 is filled with the insulating oil 12 without leaving space until the surface of oil reaches the cover 9 including the inside of the finny projecting section 2 of the radiation plate 1, and a oil-filling port is sealed and the inside of the tank is hermetically sealed completely. When a transformer is operated, the content 6 generates heat, and the insulating oil 12 is heated and expanded.

IPC: H01L23/64
Filed: 1984-05-28
Abstract: PURPOSE:To obtain accurate voltage divider by forming the pattern of a resistance wiring layer in a sawtooth shape connected with partial wiring pattern having a slope of 45 deg., thereby eliminating the adjustment of the pattern of the folded part of a resistance voltage divider. CONSTITUTION:Metal wirings of width W are connected at + or -45 deg., disposed in sawtooth shape, the mean length between adjacent terminals of voltage dividing terminal can be represented by the length (l) between representing points P, the lengths (l) between the points are all equal, and the same at the folded part. If the length (l) is considerably long with respect to the width W, the current distribution of the section Q of the middle part is uniform and equal, the voltages between voltage dividing terminals A2 and A1, A1 and A, A and B become equal to each other, thereby obtaining divided voltage having excellent linearity. According to this configuration, the misalignment of the conventional folded part can be eliminated to obviate the circuit regulation, thereby obtaining accurate resistance voltage divider and facilitating high integration.

Title: Interleaving method
Inventor: YAMAGUCHI SUSUMU
IPC: H03M13/27
Filed: 1987-05-01
Abstract: PURPOSE:To contrive the improvement of the correction capability against a code error by giving a delay in the unit of sampling data as the main interleave processing and applying the C1 interleave and the C1 de-interleave before and after the production of a 2nd error correction code. CONSTITUTION:A sampling data of a digital audio data inputted to an input terminal 1 is separated into an odd number series and an even number series by a scrambling processing section 2 and the odd number series is retarded by a prescribed time (T- block) with respect to the even number series. Then a C2 encoder processing section 3 generates an error C2 correction code from a data whose arrangement is changed by the processing section 2. Thus, a main interleave processing section 4 applies different linear delay to them in the unit of sampling data to interleave the C2 error correction code in time series. Then a C1 interleave processing section 5 retards the low-order symbol of the sampling data for a prescribed time (1 block) and a C1 encoder processing section 6 generates a C1 error correction code. Then the C1 error correction code is added to the data series retarded by the processing section 5, and a C1 de- interleave processing section 7 constitutes one block while the high-order symbol of the sampling data is retarded for the same time (one block) by the C1 de-interleave processing section 7 to apply recording onto a recording medium.
