Filed: 1983-07-13
Abstract: PURPOSE:To attain ease of consititution of a coder and a decoder by operating a TV camera at the transmission side and a TV receiver at the reception side based on a signal of an independent frequency source. CONSTITUTION:A difference between a TV signal inputted from an input terminal 3 and an output of a forecasting circuit 4 is obtained by a difference circuit 5 and the result is quantized by a quantization circuit 6.

Title: Magnetic head
Inventor: KAWAKUBO YOUICHI
IPC: G11B19/04
Filed: 1985-06-12
Abstract: PURPOSE:To detect that a recording medium is brought into contact with and is slided on a magnetic head, by detecting the reflection state of a laser beam from the surface of the recording medium. CONSTITUTION:The laser beam which is reflected on a magnetic disc 10 and is returned to a laser 7 is stabilized in the normal operation state and has only a gentle change due to rotation of the magnetic disc. However, if a slider 5 is brought into contact with and is slided on a magnetic disc 10, the change of a high voltage is generated in a laser terminal voltage, and this change is taken out by a filter 12 and is amplified by an amplifying circuit 13 and it applied to a detecting circuit 14. When the output of the amplifier exceeds a reference value, the detecting circuit 14 discriminates the occurrence of slide to send the detection signal to a control circuit, and the control circuit stops the magentic disc and transmits an abnormality indication signal to a computer body or the like to which the magnetic head is connected. Thus, troubles due to slide are held down to a minimum.
