Inventor: ODA MIYAO
IPC: G02B6/06
Filed: 1985-09-20
Abstract: PURPOSE:To improve the image quality by repeating the arithmetic processing of the output of a sensor based on the characteristic of an optical system. CONSTITUTION:Assuming that the optical system can satisfy the conditions of isoplanatism the difference between an output image (y) of a visual device and a scalar product of the point spread function (h) of the optical system including an image fiberscope obtained by actual measurement and an appropri ately set initial value or a value Zj-1 obtained by the arithmetic processing of previous time is taken, and a value available from multiplying said difference by a constant is added to said initialized value or the previously calculated value Zj-1. Then this arithmetic processing is repeated. After the point spread function (h) and a multiplier 2 multiply an initial value read out of a memory 1, for instance, or the previous Zj-1, the multiplied value is subtracted from an image output (y) from an array sensor S, amplified by an amplifier 3, added to the previous Zj-1 from the memory 1, becomes a new value Zj, and updates the previous value Zj-1 in the memory 1.

IPC: F28F21/04
Filed: 1981-12-23
Abstract: PURPOSE:To improve the heat shock resistance by an arrangement wherein a stress buffer layer is formed near the joint portion of a hub at end faces of through-holes of a honeycomb structure and the latter, while said stress buffer layer has a thermal expansion coefficient which has little difference from that of the hub. CONSTITUTION:A stress buffer layer 6 is formed near the joint portion A of a hub 4 in at least one end face 5, 5' in which through-holes 2 of a honeycomb structure 1 opens and the structure 1. By such an arrangement, part of the through-holes 2 of the honeycomb structure 1 which is kept in contact with the hub 4 is blocked so that high temperature fluid or low temperature fluid is not allowed to flow through the through-holes 2 in that region. Further, the heat conductivity in that region is as small as about one sixth of that of the hub 4 so that a reduced temperature gradient and an improved heat shock resistance can be obtained. Moreover, the heat shock resistance can be increased further by forming the stress buffer layer 6 with a material having a thermal expansion coefficient which differs from that of the hub 4 by 0.1% or below at 800 deg.C.

Title: Level shifting circuit
Inventor: MIZUGUCHI HIROSHI
IPC: H03F3/343
Filed: 1981-12-22
Abstract: PURPOSE:To obtain a circuit of simple constitution which operates stably at a low voltage as a level shifting circuit which shifts a fine input signal by a specific level. CONSTITUTION:When the base-emitter forward voltage of a transistor (TR) 1 is nearly equal to that of a TR3, the level at an input terminal X is equal to the collector level of a TR2 unless the TR2 is saturated. When the level at the terminal X falls, the balancing state between the TRs 1 and 3 is not maintained any more and the emitter current of the TR3 is reduced. As a result, the base current of the TR2 increases and while the level at the terminal X is equal to the collector level of the TR2, the TRs 1 and 3 are balanced. On the other hand, an input voltage is shifted in terms of direct current by the voltage IoR depending upon the constant current Io of a constant current source 5 and the resistance value R of a resistance 4 and then supplied to a terminal Y.

Title: Target tracking device for guided airframe
Inventor: KUNITOKI KOUICHI
IPC: G01S13/68
Filed: 1981-12-23
Abstract: PURPOSE:To enable the discrimination and tracking for one of targets flying in formation, by tracking the target within a tracking band width with use of a BPF of a smaller band width than that and therefore detecting a small difference of temperature of the targets flying in formation. CONSTITUTION:A circuit having a tracking function including a local oscillator 1a, a mixer 2a, a BPF3a, a frequency discriminating circuit 4a, an LPF5a and a control circuit 6a is provided at the output side of a BPF3. In this case, the pass band width SW2 of the BPF3a is set smaller than the pass band width BW1 of the BPF3. Then one of the targets a1, a2, a3 and a4 within the width BW1 is detected by varying the oscillating frequency of the oscillator 1a. This selected target is tracked. Therefore, the output of the BPF3a includes only the signal of the target a3, and it is possible for an angle error detecting circuit 7 to detect an error to the target a3. This enables to discriminate and track one of the targets flying in formation.

Title: Overwritable magneto-optical recording method, magneto-optical recording medium used by same and magneto-optical reproducing method
Inventor: SATOU MASATOSHI
IPC: G11B11/10
Filed: 1986-09-04
Abstract: PURPOSE:To cast a narrowed laser beam on the front of a track and to set a recording width below a prescribed one by exploiting laser's cohesive property excellent in terms of space and hour and narrowing a beam to a spot almost the same as a diffraction limit determined by the wavelength of a laser beam. CONSTITUTION:The laser beam L is narrowed and heated on the recording layer of a substrate 20a in an optical magnetic recording body. A recording magnetic field Hb with a direction opposite to an initialized field during the heating is impressed on the heated part from the outside. By impressing the recording magnetic field Hb, the coercive force Hc of the heated part is partially decreased to minimize the recording magnetic field Hb. As a result, the magnetization of the part is in the direction of the recording magnetic field Hb to form a magnetized bit conversely. The cohesive property of the laser is exploited to project a small spot narrowed to the same level of the diffraction limit determined by the laser beam on the track, and a bit with a width narrower than a prescribed one is formed on the recording layer accordingly.

IPC: G02F1/1343
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device which allows driving with a low voltage and has excellent display characteristics. SOLUTION: Comb-shaped pixel electrodes 11 and common electrodes 12 are arranged on a substrate 13 and a counter substrate 14 in such a manner that the teeth of respective combs are paralleled and alternated with each other. When voltage is impressed on the liquid crystal display device, an electric field in a diagonal direction is generated by the pixel electrodes 11 and the common electrodes 12 and liquid crystal molecules 10b having positive dielectric anisotropy are oriented along the electric field in a diagonal direction. The pixel electrodes 11 and the common electrodes 12 are preferably arranged by parting the spacings therebetween in such a manner that the electric field in a diagonal direction is made more nearly horizontal in order to eliminate the dependence of the liquid crystal molecules 10b on visual field angles.  On the other hand, a higher driving voltage is made necessary in order to make the inter-electrode spacing larger. Then, the angle A formed by the electric field direction with the substrate surface with respect to the liquid crystal display device having a cell gap of 4 to 10μm is set larger than 20 deg. and below 45 deg..

Abstract: PURPOSE:To reduce the manufacturing cost of the anode body structure in the title, by forming at least either one of each anode strap and a microwave output leading-out conductor, out of copper, coating its surface with a metallic plating layer of thermal conductivity lower than that of the copper, and radiating laser beams onto the conjoined portion of the anode strap or the conductor and each anode vane for melting the plating layer. CONSTITUTION:At least either one of each of anode straps 9, 10 which short- circuit many copper anode vanes, 2a, 2b alternately, and a microwave output leading-out conductor 11 mounted onto one of these anode vanes, 2a, 2b is formed out of copper and then, its surface is coated with a metallic plating layer having its thermal conductivity lower than that of the copper so that laser beams are radiated onto conjoined portions of the anode straps 9, 10 or the conductor 11, and the anode vanes, 2a, 2b for melting plating layers, 9b to 11b. A fast sticking effect can be produced accordingly without any hindrance, even if the plating layers, 9b to 11b have their melting point higher than that of the copper. This procedure eliminates the necessity of a heating furnace for melting a silver soldering material as in the prior art process so that the cost of soldering can be reduced.
