Patent JP-S6222243-A (JP)
Title: Optical head device
Inventor: TODE HIDEKAZU
IPC: G11B7/08
Filed: 1985-07-23
Abstract: PURPOSE:To improve the quality of a read signal by providing a correction optical element changing the position of an optical axis of a focusing lens and its direction between a light source and the focusing lens being an optical means so as to pass the optical axis of the focusing lens through the light source. CONSTITUTION:In providing the correction optical element 9 comprising a collimated glass plate with a tilt to the optical axis 8, the optical axis 8 is displaced by a quantity depending on the tilt angle of the correction optical element 9 while the direction is not changed. Through the utilization of the principles above, the tilt of the correction optical element 9 is adjusted to give a proper displacement to the optical axis 8 thereby correcting the deviation with the light source 1. As a result, the irradiated luminous flux 2 from the light source 1 becomes an axial object point light through the focusing lens 4 and an ideally small collected spot is irradiated on an information recording medium 3 without aberration. Thus, jitter of the read signal is decreased and the modulation is improved so as to improve the equality of the read signal.

Title: Control device for counterbalance valve
Inventor: DOI TOSHIAKI
IPC: F15B11/02
Filed: 1984-07-31
Abstract: PURPOSE:To prevent generation of hunting, by indexing a target value of displacement of a control spool and directly controlling the target displacement to adjust an opening of a control unit. CONSTITUTION:A flow sensor 43 is provided in a passage 11, and a pressure sensor 44 is provided in a passage 13. A flow signal and a pressure signal are applied to an operating unit 40. A target flow rate of return oil from a bottom chamber 12 is calculated in the operating unit 40, and a target opening of a control unit is computed on the basis of the target flow rate to directly control a control spool of a counterbalance valve C. Accordingly, when a counter load is applied, the control spool may be controlled irrespective of pressure on the side of a supply passage. Therefore, even when fluctuation in the pressure on the side of the supply passage is large, it is possible to prevent generation of hunting.

Title: Frequency modulating circuit
Inventor: ISHIDA MASAHARU
IPC: H03C3/24
Filed: 1980-11-17
Abstract: PURPOSE:To remarkably suppress the dispersion in the degree of modulation and to enable nonmodulation of the degree of modulation, by returning a feedback signal for oscillation to a connecting point between a circuit converting a modulation signal into a current and a transistor. CONSTITUTION:A conversion output of a current conversion circuit 22 is applied from the collector of a transistor TR24 to a TR2, and the gm of the TR2 is changed. As a result, the oscillating frequency of an oscillation circuit having a feedback loop consisting of a tank circuit with a capacitor C and a coil 16, TR2 and capacitors 18, 20 is changed and a frequency modulation output can be obtained. Since a feedback signal from a capacitor 14 and the coil 16 is returned to a connecting point between the TRs 2 and 24 which are not subjected to the effect of a resistance value, the amount of feedback can be decided only with the impedance value of the capacitors 18, 20. Thus, the dispersion in the degree of modulation due to the resistance value can be suppressed remarkably as conventional cases, adjustment of the degree of modulation can not be achieved, and the circuit is most suited to circuit integration.

Title: Burst wave detector
Inventor: OIDE TAKAYOSHI
IPC: H04L27/22
Filed: 1991-07-03
Abstract: PURPOSE:To improve the detection accuracy of an incoming signal wave by identifying two distributions of a detector output. CONSTITUTION:A detection voltage obtained by detecting a burst signal wave modulated and arrived at random by a detector is given to an amplitude detection circuit 1, in which square of the voltages are summed and rooted and the resulting amplitude is inputted to a moving mean circuit 2, where the amplitude at a time t0 and an amplitude in an optional n-clock preceding time t0-n are averaged. Thus, two distributions of probability density of the detected voltage with respect to the moving mean amplitude are both made steep and its variance is decreased. Since the overlapped part of the Rhys distribution of the probability density of the detection voltage with respect to the amplitude and the Rayleigh distribution at noise only in the absence of the arrival signal is less, the probability of occurrence of non-detection and mis-detection with respect to an input signal wave is considerably reduced. Then the moving mean value is compared with a reference value at a comparator 3 and when the moving mean value is more than the reference value, a demodulator 4 is operated.

Abstract: PURPOSE:To enable high density recording by making two subcarriers that synchronize relative movement between a video head and a magnetic medium and intersect at right angles a color tone when magnetically recording a carrier luminance signal at different azimuth between adjacent tracks. CONSTITUTION:Three kinds of carriers (1)-Asineomegact, (2) Acosomegact, (3) Asinomegact are made from output of an oscillator 1 by a phase shifter 2.

Another chrominance signal EB-Y and the signal 2 are inputted to another balanced modulator 5 and the signal 3 is added to this balanced modulation wave to make another carrier chrominance signal CB (t). After multiplexing + or -CR (t) and CB (t), a signal 21 made by composing the carrier luminance signal CY (t) and a reference signal fP is recorded by using inclined azimuth so that horizontal synchronizing signals are made uniform and phases of signals 2, 3 are made uniform between adjacent tracks.
