Title: Voltage controlled oscillator
Inventor: OMORI HIDEKI
IPC: H03B5/12
Filed: 1994-03-17
Abstract: PURPOSE:To realize oscillation in a wide frequency range by supplying a control voltage to an oscillation circuit through a bias circuit consisting of elements set in prescribed conditions to suppress the voltage drop due to rectification of a varactor diode of the oscillation circuit. CONSTITUTION:The DC control voltage from a terminal 5 is supplied to an oscillation circuit 9 through a bias circuit 10. At this time, impedance elements 6 and 7 and a capacity element 8 of a bias circuit 10 constitute low pass filters having cut-off frequencies f1 and f2 respectively, and elements 6, 7, and 8 are so set that f1<f2 and f1>f2 are true where f0 is the oscillation frequency. Consequently, the impedance is low when viewed from the oscillation circuit 9 but is high when viewed from the input terminal 5, and generation of the voltage due to the rectifying action of a varactor diode 3 is suppressed, and reduction of the control voltage is suppressed to supply the control voltage to the oscillation circuit. Thus, the oscillation frequency range is approximately equal to theoretically obtained one.

Filed: 1981-03-31
Abstract: PURPOSE:To prevent an image from coloring by providing curved-surface parts, which slant in the opposite direction to slanting parts for distance measurement, in unit grating parts of a multiple eschelette type grating. CONSTITUTION:A multiple eschelette type grating as a substitute for a split image prism performs distance measurement over a wide F-number range precisely, but an image may color possibly in a large-F-value range or when an eye shifts from a finder optical axis.

Consequently, the wavelength dependency of the optical path is reduced to make the image hard to color, and the distance measurement is facilitated regradless of an F number and the position of the eye.

By changing a position, the sliding member 10 can change the biting position of the brake arm 6, and can freely change the magnitude of the braking torque. Thus the excessive tension is prevented from being generated on the magnetic tape when the reel base 5 is stopped.
