IPC: G11B20/02
Filed: 1988-02-15
Abstract: PURPOSE:To obtain a magnetic recording and reproducing device which is free from inversion on its black-and-white screen by detecting a component which is different from the frequency component of the reproduced signals reproduced by its own device from reproduced signals and correcting the frequency and phase characteristics of the reproduced signals in accordance with the detected frequency component. CONSTITUTION:A frequency component detector 9 which detects a frequency component peculiar in the reproduced signals reproduced by another device from reproduced signals extracts frequency components f1-f3 which appear in accordance with the equalizer characteristic at the time of recording. By actuating frequency characteristic correcting amplifiers 31-33 and phase correctors 40-43 respectively corresponding to switches, the equalizer characteristic of the equalizer circuit 3 at the time of reproduction by another device is caused by compensate the equalizer characteristic at the time of recording. Therefore, at the time of reproduction by its own device only an equalizer amplifier 30 and phase corrector 40 are actuated to compensate the equalizer characteristic at the time of recording by its own device and, at the time of reproduction by another device, the equalizer characteristic of the reproduced signals are switched by discriminating the equalizer characteristic at the time of recording and the equalizer characteristic is compensated. Therefore, high-quality reproduced video signals which are free from white-black inversion are obtained in the case of not only the reproduction by its own device, but also the reproduction by another device.

A circuit R consisting of the comparator 11 and a flip-flop 14 constitutes of a data identifier, and the outputs of flip-flops 15 and 16 are applied to an AND circuit 17. The flip-flop 15 outputs ''1'' when an input signal is lower than Vth+DELTA; while the flip-flop 16 outputs ''1'' when the input signal is higher than Vth-DELTA. Thus an output of ''1'' is obtained from the circuit 17 when the input signal is set at Vth+ or -DELTA. A counter 19 counts the outputs fed from the circuit 17 to count the signals entering an area of oblique lines shown in a figure.

Filed: 1983-03-03
Abstract: PURPOSE:To meet quick temperature change, enhance mechanical reliability and improve operation efficiency by forming a thermal conductive layer consisting of good thermal conductive material is formed to a protruded body in such a way as being placed in contact with it and is connected to a mother body. CONSTITUTION:A thermal conductive layer 8 consisting of copper and aluminium having good thermal conductivity is placed and connected in contact with a helium tank 2 at the surface of protruded reinforcing plate 2a and supporting leg 2b. As a method of placing the thermal conductive layer 8 in contact with the protruded bodies 2a, 2b and helium tank 2, it is just suited to weld a plate by the exprosion welding or to thermally spray copper or aluminium in order to form a layer at the surface. Or, a pair of reinforcing plates 2a, 2a are welded keeping a space and a good thermal conductive material is thermally sprayed to such space and thereby a layer 8 is formed. Thereby, during a preheating before the liquid helium is pored to the helium tank 2 or during temperature rise to the normal temperature after the liquid helium has been pored, heat is transmitted quickly by the thermal conductive layer 8 placed in contact with the protruded body from the helium tank 2. Accordingly, the tank as a whole is almost simultaneously heated to the same temperature.
