Title: High-sensitivity superconducting digitizer
Inventor: AANORUDO EICHI SHIRUBUAA
IPC: G01R19/25
Filed: 1993-07-22
Abstract: PURPOSE: To input a magnetic flux obtained by converting an input current and positive and negative modulated magnetic fluxes from a waveform generator to a d.c. squid to generate a pulse train which is the period function of the input, determine the difference between frequencies of the squid outputs by positive and negative signals, integrate them by an integrator to apply an analog negative feedback, and also generate a digital output. CONSTITUTION: A coil 36 converts an input current to a magnetic flux, and a waveform generator 46 generates three-state modulatedmagnetic flux signals of positive, negative and zero. A d.c. squid 38 inputs both the magnetic fluxes and generates a pulse train having a frequency which is the period function of the input. A switch 52 is controlled by the generator 46 to distribute the pulse train to the up side or down side terminal, of an up - down counter 60 according to positive and negative, and generates a difference between pulse frequencies of the squid 38. A digital integrator 70 integrates the differential output of the counter 50. A D/A converter 72 converts this output and imparts an analog negative feedback magnetic flux. A digital filter 66 inputs the integrator 70 and generates a digital output.

Title: Optical head
Inventor: ANDOU HIDEO
IPC: G11B7/1381
Filed: 1983-09-29
Abstract: PURPOSE:To stabilize electrically a detection when an out-of-focus quantity has become large, by constituting a titled head so that light protrudes from a projecting lens when the out-of-focus quantity is large, and reducing the sum total of an out-of-focus signal. CONSTITUTION:An out-of-focus detection is executed by an objective lens 5, a light shielding plate 13, a projecting lens 15 and a photodetector 16. In this case, the radius of the projecting lens 15 is designed so that a large out-of-focus is detected for the first time in a state that only 1/4 total area of a laser spot passes through the projecting lens 15 and reaches the photodetector 16, by a specified expression base on particulars of said optical system and a working distance of the lens 5. Therefore, it is detected that the lens 5 has approached a disk abnormally. In this way, when an out-of-focus quantity has become very large, a light quantity going toward the photodetector 16 is reduced, and the sum total of the light quantity to the photodetecting cell 16 is reduced. As a result, an output voltage of an adding circuit 25 becomes small, and by determining in advance a reference value to a CPU27, a state that an out-of-focus quantity is very large is decided.

Title: Phase locked oscillator
Inventor: NAKAYAMA AKIHIKO
IPC: H04L7/00
Filed: 1988-07-22
Abstract: PURPOSE:To always output a stable clock pulse by performing phase control by using the state information of an input clock signal in addition to the phase difference information of the input clock signal and an output clock signal as phase control information for a phase controlled oscillator. CONSTITUTION:A phase comparator 10 compares the phase of the input clock signal with that of the output clock signal outputted from the phase controlled oscillator 30, and outputs a phase difference signal representing the phase difference of them to the phase controlled oscillator 30. Meanwhile, a protection circuit 20 always monitors the state of the input signal, and outputs a phase control suppression signal to suppress the phase control to the phase controlled oscillator 30 when the abnormal state of the clock signal is generated for the regulated number of times or more within a constant time. Here, at a time when it is judged that the input clock signal functions normally for a regulated time or more by the protection circuit 20, the output of the phase control suppression signal is stopped. In such a way, since the phase control is performed only when the input clock pulse functions normally, it is possible to output the stable clock pulse even when the input clock pulse functions abnormally.

Title: Magnetic bubble device
Inventor: SUZUKI MAKOTO
IPC: G11C19/08
Filed: 1985-08-21
Abstract: PURPOSE:To increase the data transfer speed with a few detection circuits by combining at least >=2 sets of thick film detectors having different patterns to form an electric bridge. CONSTITUTION:When a magnetic bubble passes beneath a detection line, the resistance of the detection line is changed by a leakage magnetic field from the magnetic bubble and an output is obtained by taking a difference from the resistance of a detection line (dummy detection line) through which no magnetic bubble passes, and the output waveform depends on the shape of the detection line. Detection lines 7 having different patterns are combined to form a bridge, then sum of outputs of the two detection lines 7 appears and since the phase of main peaks P1a, P1b is different, each peak is detected. Thus, a thick film detector is used, one detector processes plural detectors to increase the data transfer speed.
