Title: Thermomagneto-optical recording medium
Inventor: KUDO TOSHIO
IPC: G11B11/10
Filed: 1989-10-20
Abstract: PURPOSE:To increase a Kerr rotating angle even if a Kerr enhancement layer is extremely thin and is single layer and to obtain good reproducing characteristics by having the enhancement layer which is formed by sputtering vapor deposition and contains Zn and S. CONSTITUTION:The ZnS layer formed by the sputtering vapor deposition is provided as the Kerr enhancement layer 3. The effect of enhancing the Kerr rotating angle is, therefore, extremely increased and the performance index (Kerr rotating angle X reflectivity) can be increased as well by controlling the thickness of a recording layer 2 and the wavelength of the light to be projected according to the material of the above-mentioned layer. Further, the refractive index of the light in the transparent region of the ZnS layer can be increased to the value above 2.3 and the matching with the recording layer 2 consisting of the amorphous alloy of a rare earth-transition metals, etc. is improved. The Kerr rotating angle and performance index are improved in this way even if the thickness of the ZnS layer 3 is small. The extremely good reproducing characteristics are thus obtd.

Title: Time counting instrument
Inventor: SATO IESATO
IPC: G01S13/10
Filed: 1984-12-24
Abstract: PURPOSE:To eliminate the need for correction when the 2nd signal is not generated by setting a specific reference time from the point of time when the 1st signal is generated, and counting the time from the point of time of the generation of the 2nd signal to the end of the reference time and calculating the time between both signals. CONSTITUTION:A device which counts the time from the generation of the 1st signal A to the generation of the 2nd signal B is provided with a timer 2 in which the specific time longer than an estimated time is set. The timer 2 is started simultaneously with the generation of the 1st signal A and a counter 11 counts clock pulses generated from the generation of the 2nd signal B to the end of the reference time of the timer 2. The counted time is subtracted from the reference time to calculate the time between both signals A and B. Consequently, the counter 11 does not operate unless the 2nd signal B is generated, so an error in measurement is eliminated.

Title: D/a converter
Inventor: KADAKA TAKAYUKI
IPC: H03H17/02
Filed: 1990-10-12
Abstract: PURPOSE:To obtain a low-noise analog output by frequency-dividing a system clock signal having a frequency fs into <=fs/4 and, at the same time, passing a signal to be filtered through a low-pass filter after generating the signal to be filtered within one period of the frequency-divided clock signal. CONSTITUTION:A filtered signal generation circuit 20 forms a frequency-divided clock signal phi2 having a frequency fs/4 by frequency-dividing a system clock signal phis having a frequency fs. Since the signal phi2 contains no leakage noise, the signal content of the output B of a noise shaper is detected based on the signal phi2. The detection of the signal content of the output B of the noise shaper is performed at every period (1/fs) of the system clock signal phis in one period (fs/4) of the signal phi2. Then a signal CO to be filtered having a pulse width corresponding to the detected signal content is generated at every detecting period and supplied to an LPF 18. Thus, an analog output AO corresponding to the digital input DI can be obtained from the LPF 18.
