Filed: 1988-08-18
Abstract: PURPOSE:To maintain the quality of a system clock by providing a peak hold circuit, an A/D converting circuit and a cound down circuit and executing the optimum control of sampling timing for phase comparison between a reproducing clock and the system clock. CONSTITUTION:When the peak value of the control voltage of a voltage control oscillator 7 is small, the C/N of a line is satisfactory and a point, for which a reproducing clock 2 has the most satisfactory quality as a clock, is in front of a bit timing recovery window.

Inventor: MINAMINO IKUO
IPC: G11B7/09
Filed: 1985-09-18
Abstract: PURPOSE:To decrease the crossing speed at a just focus position with a simple constitution and to perform secure automatic focusing operation by fitting focus iron pieces to the flank of the cylindrical part of an objective lens holder. CONSTITUTION:The focus iron pieces 19 and 20 which generate focus-directional force to the objective holder 6 are fitted on the flank of the cylindrical part of the holder 6 and normally positioned in a magnetic gap. When the iron pieces 19 and 20 are in the magnetic gap, no force operates on the iron pieces 19 and 20 in very direction, but when the lens 14 approaches to the just forcus position and moves out of the gap, attractive force which attracts the lens back into the gap operates on the iron pieces 19 and 20. This attractive force serves as braking force to decrease the crossing speed of the lens at the just focus position, so that the automatic focusing operation is performed securely without any failure.

Abstract: PURPOSE:To widen the supply voltage range which can be used at the time of testing. by connecting an NMOS transistor, whose resistance value varies transmissively with he supply voltage, with the grounding side of a final stage inversion circuit. CONSTITUTION:When the input voltage to an input terminal 52 is raised over a voltage VDD from a power supply 51 to cause the difference from it VDD to attain the threshold voltage of a PMOS transistor 1, a channel thereof 1 is turned on, and if the input voltage is further raised to cause the channel resistance of the transistor 1 to sink below that of an NMOS transistor 2, a higher voltage than the logical threshold voltage is fed to an inverting circuit consisting of a PMOS transistor 3 and an NMOS transistor 4, and the output of the output terminal 55 is turned to L-level. In the low voltage range, however, the channel resistance of an NMOS transistor 5 becomes smaller as the voltage VDD rises, and the logical threshold voltage of tone inverting circuit becomes a lower value, so that the input voltage VDET with which the inverted output is obtained becomes a low value, and the level range of the service voltage VDD is widened.

Abstract: PURPOSE:To increase engine output in the service rotation region to improve acceleration property in an ignition timing control device of an internal-combustion engine equipped with a supercharger by reducing delay angle control quantity at ignition timing in a partial load region where supercharging pressure does not reach a limited value. CONSTITUTION:In an ignition timing control device, when a transistor 22 is turned on, an electrode of a resistance 21 connected to a collector of the transistor 22 has earth potential and the output of an analog gate 3 is divided by resistances 20, 21 to be sent to the input of a noise level detector 5.
