Filed: 1980-02-20
Abstract: PURPOSE:To regenerate a frequency-multiplexed signal with an excellent S/N ratio like a luminance signal and color signal, by providing windings to a magnetic head having a single working gap and by providing a signal regenerating circuit to every winding. CONSTITUTION:A luminance signal induced at winding 6a is peaked by rotary transformer 7a, step-up transformer 8a, capacitor 14, etc., to obtain a signal with a sufficient level, which is supplied to regenerative amplifier 9 to be led out via HPF10 as a signal with an excellent S/N ratio. On the other hand, although a color signal induced at winding 6b is processed by a similar circuit, the number of winding turns of winding 6b is increased and the boosting ratio of the circuit is also increased to obtain a chrominance signal with an excellent S/N ratio by way of LPF11. Therefore, both the luminance and chrominance signals can be regenerated by magnetic head 3 having a single working gap with an excellent S/N ratio.

Title: Power consumption controller
Inventor: NAKAGAWA TOSHIYUKI
IPC: H02J3/00
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To use power up to the contract power and prevent the frequent stop of one and the same load by providing a linear control section for linearly controlling the power consumption of a load and an on/off control section for separating the load based on an output signal of the linear control section. SOLUTION: When the power consumption is a little bit over the contract power, a control section 5 controls a linear control section 7 based on the setting conditions of a setting section 6 to bring down the power consumption within the contract power by phase control or step-down control of a load. When the power consumption is well over the contract power, the control section 5 controls an on/off control section 8 based on the setting conditions of the setting section 6 to separate the load and bring down the power consumption within the contract power. By this method, the power consumption can be always kept within the contract power and one and the same load never stops frequently.

IPC: G11B5/48
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To avoid crosstalk from adjacent tracks. SOLUTION: At least a 1st magnetic layer 11 and a 2nd magnetic layer 12 are laminated, and the 1st magnetic layer 11 has a high coercive force at around room temperature and is formed of a magnetic layer having a Curie- point higher than that of the 2nd magnetic layer 12, and the 2nd magnetic layer 12 is formed of a magnetic layer of which the axis of easy magnetization is almost in the direction of the film plane in the Curie-point temperature range of the 2nd magnetic layer 12 from the room temperature.  And, crosstalk from adjacent tracks is avoided by reproducing the recorded information recorded on this information recording medium 1 as an information magnetic domain by detecting the leakage magnetic field due to the information magnetic domain under optical assistance, namely, optical irradiation, and limiting a deriving part of the leakage magnetic field from the record information magnetic domain of the 1st magnetic layer 11 by the 2nd magnetic layer 12.

Title: Electro-optical light modulator
Inventor: KONDOU MITSUKAZU
IPC: G02F1/03
Filed: 1978-02-21
Abstract: PURPOSE: To facilitate production and increase quenching ratio by evenly applying the electric field perpendicular to the light transmission direction by using the crystal whose optical anisotropy is small and changes gradually in the light transmission direction.  
     CONSTITUTION: A light modulating medium 21 is cut out from a lithium tantalate crystal and its composition ratio of Li and Ta is selected at around 1.2 so that the refractive index n e  to abnormal light and the refractive index n 0  to normal light become approximately equal. Namely, if ε is assumed to be a positive number infinitely close to 0, it is 0 ≠ |n e  - n 0 | < ε. The value of n e  - n o  gradually changes in the Y-axis direction being the growth direction of the crystal. The electric field of the X-axis direction is evenly applied by a signal generator 22 and electrodes 23. Since this applied electric field and Pockels coefficient r 51  cause the main axis of the refractive index ellipsoid of the medium 21 to rotate, part of the incident light 24 polarized in the X-axis direction is converted to the polarized component of the Z-axis direction. This light then passes through an analyzer 25 to become exit light 26.

Title: Holographic radar
Inventor: OHASHI YOSHIMASA
IPC: G01S7/02
Filed: 1987-01-29
Abstract: PURPOSE:To prevent the lowering of the sensitivity of a radar even when a target is present in a valley of fixed beams, by providing phase shifters conducting prescribed phase shift of the respective outputs of receiving antennas, and by making the amounts of these phase shift variable. CONSTITUTION:A reflected signal from a target is received by receiving antennas 1 in the number of N and inputted to phase shifters 4 in the number of N. Then, the phase of #K (K=0, 1...N-1) phase shifter 4 is obtained by a beam steering computer 5. By using lambda as the wavelength of a carrier wave, f0 as the frequency thereof, alpha as an interval of disposition of the receiving antennas 1 and alphaT as a deviation angle of a beam at the time when it is formed by the receiving antenna 1, Formula I is obtained as an output of a beam- forming circuit 3. A beam direction alphar obtained by r=0, 1, 2...N-1 with thetaB=lambda/Nd herein is given by alphar=cos<-1>(rthetaB+cosalphaT). Accordingly, when the phase is given to the phase shifter 4 appropriately by the computer 5, the target can be caught approximately at the top of a beam formed in the circuit 3, and thus the lowering of an antenna gain can be prevented.
