Title: Method and device for linearization of operation of external optical modulator
Inventor: YUUDEI TORISUNO
IPC: G02F1/01
Filed: 1991-09-12
Abstract: PURPOSE: To economically and easily produce a device for reducing harmonic distortion by precompensating a modulation signal by an odd-order distortion component having the same component as a distortion component generated by a modulator but having reverse polarity. CONSTITUTION: An RF signal is inputted to a terminal 10 and divided by a branch 12, the phase of a branched signal is shifted by a phase shifter 16 in a 1st route, a branched signal on a 2nd route is distored by a distortion generator 14 consisting of a pair of diodes connected in parallel in the reverse polarity, and the distorted signal is inputted from an attenuator 18 to a gain controllable amplifier 20. The phase-shifted signal from the 1st route and the distored signal from the 2nd route are coupled by a coupler 22 as a modulation signal for an external modulator 30. The distortion generator 14 is an adaptive harmonic distortion generator and forms the same distortion component as distortion generated by the external modulator 30 but its phase is reversed.  The phase delay of the phase shifter 16 and the amplitude of the amplifier 20 are controlled so that optimum linearity can be obtained from the output of the modulator 30.

Title: Optical recording medium
Inventor: SATO YOSHIO
IPC: G11B7/24047
Filed: 1986-11-04
Abstract: PURPOSE:To permit partial erasure and entire erasure of a memory at a high speed by segmenting a recording film consisting of a good conductor having a high tendency to generation of eddy current by a resistant material having large specific resistance and a lower tendency to generation of eddy current to areas. CONSTITUTION:The recording film 14 is segmented to regions by insulating films 16 having the large electric resistance. The eddy current is generated in the recording film 4 if a magnetic field is generated in a core 42 by passing high frequency current to a coil 44, but the recording film 14 is partitioned by the insulating films 16 and, therefore, the spread of the generated eddy current over the entire surface of a disk is prevented by the films 16 and the concentration of the eddy current is permitted. The local and efficient heating of the film 14 with small electric power is, therefore, possible. Since the heating of the adjacent recording films partitioned by the insulating films is suppressed to a lower level, the erasure of only the assigned region is possible.

Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain a bright image as a con-focal image and non-con-focal image by detecting the light which is reflected from a sample and is transmitted through a con-focal diaphragm to obtain the con-focal image, detecting the reflected light which is not passed through the con-focal diaphragm and adding the con-focal image to the non-con-focal image, thereby forming the non-con-focal image. SOLUTION: An objective lens 10 condenses the light emitted from a light source 1 onto the sample 11. Galvanomirrors 4, 7 are arranged between the light source 1 and the objective lens 10 and scans the surface of the sample 11 in directions orthogonal with each other by changing the incident angle of the light entering the objective lens 10. A first detector 18 passes the light from the sample 11 through a pinhole mirror 17 as a con-focal diaphragm, detects the light and outputs a con-focal image signal. A second detector 20 detects the light reflected without passing the con-focal diaphragm. An adder adds the con-focal image signal outputted by the first detector 18 and the output of the second detector 20 and outputs a non-con-focal image signal.

Title: Semiconductor memory
Inventor: TAGUCHI MASAO
IPC: H01L27/04
Filed: 1985-11-20
Abstract: PURPOSE:To process against a leakage current at low temperature by using a dielectric film having specific dielectric constant larger than a silicon nitride as the insulating film of a capacitor, and operating it in the state cooled colder than an ambient temperature in DRAM using a charge storage capacitor as a memory cell to increase a storage capacitance. CONSTITUTION:Capacitor electrodes 20 are contacted at the center with a diffused region 14b, risen at one side on a gate electrode 16a, at the other side on a word line 16b, and a dielectric film 22 and capacitor electrodes 24 are formed in the same shape as the electrodes 20 (stacked capacitor type). Since Ta2O5 capacitor is formed in the step after forming an MOS transistor, it is less exposed within high temperature atmosphere. Since Ta2O5 film varies in its crystal structure in atmosphere of 600 deg.C or higher, it can prevent a leakage current from abruptly increasing. PMOS is used for a transfer transistor of the memory cell to prevent a hot electron effect from occurring at low temperature. The memory cell employs a CMOS structure in n-well to prevent minority carrier from implanting to the capacitor due to alpha-ray emission.

Filed: 1988-10-17
Abstract: PURPOSE:To omit a guide pole and to obtain the stable back tension as well by using a tension regulator pole also as a guide pole at an outlet of a supply reel and changing a tape contact angle with the tension regulator pole in accordance with a tape winding diameter around a supply reel. CONSTITUTION:The tape tension regulator pole 44 of a tension arm 40 is functional as a guide, by way of which a tape to be supplied from a supply reel 18 is traveled first, so that a guide pole for regulating the position on the side of the supply reel can be eliminated. Moreover, since the tape to be supplied from the reel 18 is traveled via the pole 44 for the first time, the tape contact angle with the pole 44 is varied in accordance with the tape winding diameter of the reel 18, and hence by setting properly a lever ratio and a brake band winding angle, etc., irrespective of the winding diameter, the stable back tension can be given accordingly.
