Abstract: PURPOSE:To attain adoption to the coding information recording of a narrow track and high density by mixing pilot signals reproduced at the time of reproduction from first and second tracking areas and permitting rotary heads to follow an ideal tracing position. CONSTITUTION:ATF areas where the pilot signals f1 and f2 are recorded in a magnetic tape 22 are partially brought into contact with the ATF areas of the adjacent tracks in a head scanning direction B, and if possible, the leading end and the trailing end of one ATF area are positioned in the center part of the ATF area of the adjacent track or the adjacent track on an opposite side. At the time of reproducing an information signal, the pilot signal in signals obtained by mixing the reproducing signal of the rotary head 24A tracking the first tracking area and that of the rotary head 24B tracing the second tracking area are used, and the rotary heads are permitted to follow the objective track. Thus, adoption for coding signal recording can be attained.

Title: Comb-line filter for y/c separation
Inventor: ORIMO TATSUYA
IPC: H04N9/78
Filed: 1985-11-26
Abstract: PURPOSE:To reduce a cross color according to the deterioration in a correlation between near-by scanning lines by a simple circuit constitution by providing a correlation detecting circuit for detecting a degree of the correlation between the near-by scanning lines and a variable band passing filter circuit for sampling a chrominance signal for making the passing band narrower as the correlation detected in the correlation detecting circuit is deteriorated. CONSTITUTION:The output of a subtracter 5 is filtered by the variable band-pass filter circuit 13 for sampling the chrominance signal having a central frequency equal to a chrominance sub-carrier frequency and a passing band width varied according to the degree of the correlation between the near-by scanning lines and outputted from an output terminal 9 as the chrominance signal C. The passing band width W of the variable band-pass filter circuit 13 for sampling the chrominance signal is 1MHz when a band width control signal K is zero, namely, when the correlation between the near-by scanning lines is complete. This passing band width W is gradually reduced as the band width variable control signal K is increased, namely as the correlation between the near-by scanning lines is deteriorated. As a result, a passing component of the chrominance signal is gradually reduced and the deterioration of a picture quality is reduced.

Abstract: PROBLEM TO BE SOLVED: To enable the elevating/lowering of a tundish during electrically heat- casting by providing an electric supplying side plasma electrode shifting mechanism for contact-conducting while press-inserting the electric supplying side plasma electrode to an electric receiving side plasma electrode. SOLUTION: When an elevating arm 18, the laid and supported tundish 17 and a projected electric receiving side plasma electrode 25 are elevated/lowered by working an elevating cylinder 20, one pair of the electric supplying side plasma electrodes 35a, 35b press-inserting the electric receiving side plasma electrode, elevating cylinder 36 and an elevating frame are elevated/lowered by following up to secure the conduction between the electric supplying side and the electric receiving side. Since the elevating frame 28 is connected with a wt. 43 through a hang-supporting wire 38, the wt. related to the elevating frame 28 is reduced and the following elevating movement is smoothly executed.  By this constitution, wiring between a shifting truck and the tundish 17 is unnecessary, and the automatic fitting/removing of the electrode and the elevating/ lowering of the tundish 17 during electrically heat-casting can be executed, and the operational ratio of the continuous casting can be improved.

Title: Production of magnetic recording medium
Inventor: ICHIJO MINORU
IPC: G11B5/66
Filed: 1986-11-07
Abstract: PURPOSE:To improve durability and corrosion resistance by depositing titanate by vacuum evaporation on the surface of a thin ferromagnetic metallic film layer, then hydrolyzing the same in the atm. to provide a dense and tough protective film layer consisting of titanium dioxide which has network structure and is grown to macromolecules. CONSTITUTION:The thin ferromagnetic metallic film layer 2 consisting of cobalt is formed on a polyester film 1 and, for example, isopropyl titanate is deposited by vacuum evaporation on the thin film layer 2 and is exposed to an atmosphere of 40 deg.C and 80% RH to hydrolyze the isopropyl titanate, by which the protective film layer 3 consisting of titanium dioxide is formed. The titanate induces hydrolysis quickly when exposed to water or wet air. The titanate condenses simultaneously and grows to macromolecules to form the titanium dioxide having the network structure. The protective film layer 3 consisting of the formed titanium dioxide has the extremely good adhesiveness to the layer 2 and is further dense so that said layer has a water repelling effect. The protective film layer is thereby securely deposited on the layer 2, by which the durability and corrosion resistance of the medium are greatly improved.
