  • Patent number: 7831004
    Abstract: In a synchronous detection circuit, an interpolation circuit regulates an interpolation calculation coefficient based on phase shift information when carrying out interpolation calculation processing over a digitally converted received signal. A sampling circuit samples interpolation data using a recovered clock as a reference and two clocks having phases which are advanced and delayed with respect to the recovered clock. A phase shift detecting circuit monitors a phase shift using three sampling data output from the sampling circuit and outputting phase shift information to the interpolation circuit when detecting a predetermined phase shift. A demodulating circuit performs demodulation processing using the data subjected to the sampling with the recovered clock output from the sampling circuit. Where a synchronous shift is detected, the interpolation circuit performs regulation to match a timing having a maximum signal-to-noise ratio and the recovered clock based on the amount of the phase shift.

  • Patent number: 6815259
    Abstract: A frame-shaped holding frame which has a small thermal expansion coefficient is used. When a complex member in which a metal material is impregnated in a ceramic material, which has a smaller thermal expansion coefficient than 10 ppm/° C., is used, a warp and a wrinkle are greatly decreased. In particular, in the case of a material with a thermal expansion coefficient of 6.5 ppm/° C. or smaller, the warp and the wrinkle are not caused. When the flexible substrate is adhered to the holding frame by an adhesive, an adhesion area may be obtained so that a sufficient strength is kept. Also, since the flexible substrate is adhered onto the upper surface of the holding frame, the thickness of the holding frame is independent on fixing of the substrate. The thickness may be set so that a mechanical strength is kept and the substrate is smoothly transferred.

  • Patent number: 4562493
    Abstract: A magnetic video recording apparatus for intermittent recording comprises a magnetic tape driving circuit (30), a video signal recording circuit (20), a control circuit (40) and a recording start instructing circuit (60). The magnetic tape driving circuit (30) makes a magnetic tape (1) travel at a predetermined speed while it is enabled. The video signal recording circuit (20) records a video signal (VS) in the magnetic tape (1) in a predetermined format. The recording start instructing circuit (60) provides intermittently a recording start signal (RS). The control circuit (40) enables the magnetic tape driving circuit (30) in response to the recording start signal (RS), enables the video signal recording circuit (20) for a predetermined period of time and then disables the magnetic tape driving circuit (30).
