Title: Television receiver
Inventor: SARUGAKU TOSHIO
IPC: H04N7/01
Filed: 1991-03-04
Abstract: PURPOSE:To attain normal display without deviation in a video image and a brightness change thereof by using in-field information to the supply of a non-standard signal so as to implement the scanning line interpolation and using a discrimination signal stabilizing means so as to make the discrimination stable. CONSTITUTION:Scanning line interpolation circuits 50Y, 50C use infield information or field information other than the relevant field based on a detection signal of a moving state of a supplied video signal to implement scanning line interpolation. On the other hand, a standard signal discrimination circuit 12 discriminates a scanning line number for one field from a delayed vertical synchronizing signal to discriminate whether the signal is a standard signal or a non-standard signal. When the non-standard signal is inputted to a discrimination stabilizing circuit 14 three times consecutively from the circuit 12, its output is fed to coefficient control circuits 90Y, 90C as the non-standard signal. Then the circuits 50Y, 50C are controlled so as to implement interpolation by using only the in-field information forcibly. Thus, the discrimination is made stable and a normal video image is displayed.

Abstract: PURPOSE:To achieve a low noise by a method wherein a conductive guard which surrounds an element to be measured and a connecting cable is installed and the potential of the guard is controlled to be identical to the potential of an electrode from which a current to be measured flows out. CONSTITUTION:A guard 30 is attached to a lower-part member 2 via insulating spacers 31, 32, and it is fixed mechanically to the member 2 so as to be electrically insulated. A guard 33 forms a pair with the guard 30, and it is connected mechanically and electrically to the guard 30 by conductive thumscrews 34, 35. In addition, both of the guards 30, 33 are insulated electrically from an upper-part member 3 or the member 2. The guard 30 is connected electrically to an upper-part terminal for a standoff terminal 15 in a point 19 so that it becomes the same potential as an internal shield 11 for a measuring cable. When a measuring hig (JUG) constituted in this manner is used, the high- accuracy measurement of a very small current can be performed with good operability.

IPC: H04N9/81
Filed: 1983-04-07
Abstract: PURPOSE:To remove a crosstalk component by expanding the recording and reproduction band of a luminance signal and improving resolution, and using a delay circuit of a comb-shaped filter for crosstalk removal. CONSTITUTION:The low-frequency component of the luminance signal is multiplexed on time-division basis with a time-axis compressed line sequential color difference signal by time-axis compression or without time-axis compression and then recorded and reproduced by frequency modulation; and the high-frequency component of the luminance signal, on the other hand, is recorded by frequency conversion so that its band does not overlap a band lower than the band of an Fm time-division multiplex signal, and this is reproduced. Consequently, the recording and reproduction band of the luminance signal is expanded as compared with the present low-frequency conversion type recording and reproducing device. Further, the delay circuit of the comb-shaped filter for crosstalk removal is composed of an analog or digital memory and its amount of delay is varied by clock pulses which have variation of a reproduction time-axis to remove a crosstlak component from an adjacent track properly almost without the influence of the variation of the reproduction time axis.
