Title: Recording method of halftone image
Inventor: SUGINO TAKASHI
IPC: B41J2/205
Filed: 1980-11-27
Abstract: PURPOSE:To obtain high speed records of high quality and linear gradation by varying the reflexibility of dots by combining plural number of recording head each of which is capable of forming dots of different characteristics and by the use of a gamma compensator and a conversion ROM. CONSTITUTION:Sixteen kinds of dot form a-p can be made by combining 4 kinds of dot 11-14 of which diameter differs from other obtained by recording heads each of which differs in characteristics. Further, 16 kinds of dot form can  also be made by combining 4 kinds of dot of which diameter and reflection factor (by concentration of ink) differ from other. In reproducing image signals,  the variaion of heads and the overlap of dots are compensated by a gamma  compensator 56 and in case the dots of (h) are darker in gradation than that of  (i), the gradation of dots of (i) is exchanged with that of (h) by a conversion  ROM 58 and by this method, the linearity of gradation can be maintained.

Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To provide an optical transmission-reception module, which is applicable to the optical communication system of a subscriber system, is small-sized and is low in cost. SOLUTION: Transmission signal light emitted from a laser diode 1 in a can package 10 enters a photodiode 3 arranged slantingly to its optical axis while being diverged. 50% of the signal light entered by an optical branching element formed on the diode 3 is reflected by the diode 3 and enters a lens 11.

Abstract: PURPOSE:To enable the high speed of a chemical compound semiconductor to be taken out at the maximum by forming the gate electrode of a MESFET only on the active semiconductor layer by means of the self alignment method, thereby removing the stray capacity due to overlapping of the gate electrode and the insulating layers. CONSTITUTION:As the gate metal in forming a gate electrode by self alignment, a metal which forms a Schottky junction with a semiconductor and can be anisotropically etched is made into a lower-layer metal 47, and a metal becoming a mask for the etching of this lower-layer metal 47 is made into an upper-layer metal 48. And these are deposited on a semiconductor substrate 41 which is uneven due to insulating films 43, 46 having an opening for exposing an active layer 42 in the gate forming portion, filling up the opening. Thereafter, by planarizing the surface of the upper-layer metal 48, or by further performing overetching after the planarization, the upper-layer metal 48 is removed to a vertically extended position of the interface position where the active layer 42 faces on the semiconductor substrate surface, recessing the end portion thereof. Thereafter, with the remaining upper-layer metal 48 as a mask the lower-layer metal 47 is anisotropically etched, forming the gate electrode only on the exposed active layer 42.

Title: Fault monitoring device
Inventor: KIYOTA SHINJI
IPC: H04L25/02
Filed: 1980-11-28
Abstract: PURPOSE:To make the conventional abnormality detecting device considering S/N unnecessary, by detecting the abnormality of the transmission state by the current value consumed in a repeater station. CONSTITUTION:When a receiving signal which is not shown in figure is inputted to a repeater 1 continuously, a transmission driver which is not shown in figure consumes a required current; however, if a fault such as disconnection of the transmission line occurs, this receiving signal is broken, and the current consumption becomes small. This reduction of the current consumption for this abnormality is converted to a voltage value by a resistance element R1 inserted in series between a DC power source 7 and a power supply terminal 2 of the repeater 1. Consequently, when the abnormality occurs, the voltage supplied to the + terminal of the first operational amplifier 5 through a variable resistance RV1 is increased, and the voltage supplied to the + terminal of the second operational amplifier 6 exceeds a reference voltage determined by resistances R6 and R7, and thus, a lamp 9 indicating the abnormality is lit.

Title: Recording method for magneto-optical recording
Inventor: KIRINO FUMIYOSHI
IPC: G11B7/0055
Filed: 1993-07-07
Abstract: PURPOSE:To execute high-density magneto-optical recording by suppressing the degradation in the output of reproduced signals due to fluctuation in the recording sensitivity of a disk and deterioration of a recording film by repetition of recording/erasing at the time of test recording. CONSTITUTION:An Si3N4 film 2 is sputtered on a substrate 1 having guide grooves and a TbFeCoNb film 3, an Si3N4 film 4 and an Al95Ti5 film 5 are successively superposed thereon by sputtering. There are some other structures with which magneto-optically large Kerr rotating angles are obtainable in addition to the structure described above if optical interference is taken into consideration. Finally, the recording medium laminate is coated with a UV curing type resin 6. These films are used and further, the way of applying heat from the magneto-optical disk device to a disk is devised. Since meximum temp. of the recording film at the time of irradiation with a laser beam is lowered, the deterioration in the magnetic characteristics by the relaxation of the structure, etc., of the recording film is suppressed and the accuracy in the control of the shape of the recording magnetic domains is improved. High-density magneto- optical recording is thus possible.

The laminated type polarizer 15 is formed by alternately laminating many layers of metals and dielectrics. Only the light polarized in the direction coinciding with the lamination direction of the multilayered films transmits the films and the light polarized in the direction orthogonal therewith is absorbed by the free electrons of the metal when the arbitrarily polarized light is made incident on the polarizer. The system, such as optical fiber sensor, is miniaturized in this way.
