Title: Array antenna feeding device
Inventor: OKUMURA MINORU
IPC: H01Q3/30
Filed: 1987-11-28
Abstract: PURPOSE:To control the driving phases of all array elements by means of the smaller number of phase shifters than that of the array elements by providing first and second circulators to be respectively connected to the output terminals of an electron distributer and between first and second array elements and a non-reversible phase shifter whose input terminal and output terminal are connected between respective branching terminals of the first and second circulators. CONSTITUTION:In order to control the amplitude phase of the array element, non-reversible phase shifters 121 and 122 are used. The non-reversible phase shifters 121 and 122 have a character that transmission phases are different in the case where an electromagnetic wave is carried from the input terminals to the output terminals and in the case of where it is carried from the output terminals to the input terminals when the electromagnetic wave is carried inside them. Consequently, by means of circulators 111 and 113 connected to input terminals 161 and 162 of the non-reversible phase shifters 121 and 122 and by means of circulators 112 and 114 connected to output terminals 171 and 172 of the non-reversible phase shifters 121 and 122, by separating the electromagnetic wave to be carried from the input terminals to output terminals of the non-reversible phase shifters 121 and 122 and the electromagnetic wave to be carried from the output terminals to the input terminals, the transmission phases of the two electromagnetic waves can be set at different values by one non-reversible phase shifter.

IPC: H02J1/00
Filed: 1991-11-15
Abstract: PURPOSE:To increase the quality control level including voltage margin checking by installing the plurality of non-redundant power units, each having a higher- than-rated capacity and a redundant power unit having a rated capacity which is equal to the highest of the rated capacities of the non redundant power units or above. CONSTITUTION:Three power units 8 (8a-8c) which use an AC 100V input line 9 and a DC output line 10 in common are connected in parallel to constitute a redundant power system having a 100A output rating. When either of the three power units 8 gets down and the voltage of the output line 11 is lowered, current is supplied to a DC load from the other two units and therby the voltage of an output line 10 can be maintained normal. Each power unit 8 has a 50A output rating and therefore the maximum 150A current can be supplied from these three power units 8. By setting a capacity rating at 100A for the entire power system, the power system can work as a redundant power supply from which the normal output is supplied even if one power supply gets down.

Title: Thin-film type magnetic recording medium
Inventor: FUKUICHI TOMOHIRO
IPC: G11B5/66
Filed: 1989-11-16
Abstract: PURPOSE:To obtain a thin film type magnetic recording medium having reduced modulation noise by specifying the rotational hyterisys loss which is determined from a torque curve measured in the plane of a magnetic recording layer on a substrate. CONSTITUTION:Rotational hyterisys loss RH for various kinds of thin film type magnetic recording mediums is obtained from measurement of torque curve and the relation between the loss and modulation noise is obtained. It is found that when the rotational hyterisys loss RH is <=0.8, the modulation noise can be reduced. By using CoNi alloy for the magnetic recording layer 2 and by deviding the recording layer 2 parallel to the surface into two layers with an intermediate layer 4 interposed to decrease magnetic coupling (interaction) of two layers, the rotational hyterisys loss RH decreases and modulation noise also decreases. The intermediate layer 4 consists of, for example, Cr, Au, Ag, Pt, Bi, or Ta.

Abstract: PURPOSE:To enable the constitution of a solid key top part of a thin form having excellent durability by forming a contact point for conducting a key input by the contact with a metal outer casing having flexibility in the inner side opposite position to the outer casing. CONSTITUTION:An opening part is provided in the pressure sensitive adhesive 4 part corresponding to a key top part, and an outer casing 1 having flexibility as the key top and a distributing board 3 are opposed to each other at a fixed space through the pressure sensitive adhesive 4 as a spacer.

Title: Heat resistant member and production thereof
Inventor: OHINATA YOSHIHIRO
IPC: C04B41/85
Filed: 1992-11-12
Abstract: PURPOSE:To obtain a inexpensive, lightweight and durable heat resistant member by forming a fireproofing coating layer on the surface of a base body consisting of a porous material. CONSTITUTION:The fireproofing coating layer 3 which is dense at the surface side, and porous at the side of the joining interface to the base body and whose porosity is gradually decreased from the joining interface to the surface is formed on the surface of the base body 2 consisting of the porous material. The surface of the base body is spray-coated plural times with the slurry of the fireproofing inorganic material powder so as to be smaller in particle size in proportion as the layer is upper and is fired. As a result, the concentration of thermal and mechanical stress caused by the difference of density and thermal expansion between the base body and the coating layer is prevented by making the density in the vicinity of the joining interface to the base body approximate to the density of the base body. The stress is uniformly distributed by giving inclination to the density of the coating layer. The surface of the coating layer is made dense to prevent the diffusion of the components of the material to be fired, the deterioration of base body caused by the reaction of the diffusion components with the base body is prevented.

Abstract: PURPOSE:To miniaturize and simplify the entire part of a display device by constituting the device in such a manner that a relay lens system is made approximately telecentric to the display means side. CONSTITUTION:The luminous flux La based on the image information displayed on a display means 11 is condensed by a relay lens system 12 and the aerial image of the image information is formed in an intermediate imaging position 13. The luminous flux La is thereafter made incident on a condenser mirror 15 via a beam splitter 14 arranged in front of an observer.

Title: Fingerprint collating device
Inventor: OMORI TADASHI
IPC: G06K9/00
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To obtain a fingerprint collating device which compares an important part unless a fingerprint can be collated sufficiently, and eliminate an inadequate authorization judgement in case of illegal use, etc., of a password number. SOLUTION: Even when a collating means 14 does not perform collation in the case of a fingerprint unable to be collated, a forcible identification judgement 24 is outputted when a feature point numerical/value 19 as a feature of a fingerprint having small unevenness is an abnormal value deviating from a specific range value 21. An authorization decision 17 is outputted through the output of the forcible identification judgement 24. Consequently, even when the fingerprint can not be collated, an authorization judgement 17 is never outputted for the fingerprint having small unevenness only in response to the matching of a password number 8, thereby eliminating an inadequate authorization judgement 17 in case of the illegal use, etc., of the password number 8. Consequently, discrimination performance of high reliability by a fingerprint collation system is displayed.
