Title: Magnetic recorder and reproducer
Inventor: NAGATSUKA SHINTAROU
IPC: H04N5/7826
Filed: 1980-03-13
Abstract: PURPOSE:To ensure an assured compensation for a shift of the tracking position of a magnetic head, by superposing the pilot signal on the horizontal synchronous signal period for recording in the recording mode and extracting the crosstalk component of the pilot signals of the adjacent tracks in the reproduction mode to compare the amplitudes of both signals with each other. CONSTITUTION:The video signals supplied to the input terminal 15 are divided into the luminance signal group and the color signal group. At the same time, in each horizontal synchronous signal period, the pilot signal, which is selected to position at the middle between the luminance signal received a frequency modulation during a recording and the carrier chrominance signal received a low-range conversion and put outside the band of the video signal information, is superposed on both the luminance FM signal and the carrier chrominance signal and mixed up by a mixer 21 to be supplied to the magnetic head A(B) for recording. As the pilot signal is selected outside the band of the video signal, the crosstalk component can be extracted assuredly during a reproduction for the pilot signals of the adjacent tracks. As a result, a highly accurate compensation is possible for a shift of the tracking position of a magnetic head.

Title: High-frequency transistor
Inventor: ISHII KYOICHI
IPC: H01L21/8222
Filed: 1985-02-19
Abstract: PURPOSE:To obtain a small-sized high-frequency transistor and high-frequency characteristics of large gains by increasing impedance on the input side of the high-frequency transistor. CONSTITUTION:Since emitter DC currents in a first transistor 11 flow through an inductance 19 and do not flow through a second transistor 15, the efficiency of a collector is not lowered, and high-frequency currents do not flow through the inductance 19, and flow through the second transistor 15 and are amplified. That is, the second transistor 15 conducts C class operation as high-efficiency operation, and conducts operation optimum for high-output amplification at high frequency. Since the treating power of the first transistor 11 is reduced only by the power gain section of the second transistor 15, the peripheral length of an emitter short only by a section corresponding to the power gain section is sufficient, thus realizing a transistor having high input impedance.
