Patent number: 5215338Abstract: A universally articulable supporting sheath comprises an interconnected series of links, each having a convex spherical surface at one end, and a concave spherical surface at its opposite end. The concave and convex surfaces mate with one another to form the sheath. Special links having branch openings may be provided. Various forms of waterproofing seals are provided, including O-rings, axially compressed rings, flexible belts, and ridges on the spherical surfaces. The links can be fitted together by thermal expansion. However, an axially split link is also described, which comprises two parts which snap together. The split parts may be molded as a unit with an integral thin wall hinge. The bending characteristics and bending radius of a sheath can be modified by insertion of spacers between the links at selected locations, or by the insertion of pins into radial holes provided in the links.Type: GrantFiled: December 2, 1991Date of Patent: June 1, 1993Assignee: Tsubakimoto Chain Co.Inventors: Akira Kimura, Nobuo Kitao, Hiroshi Yasuda, Kiyoshi Isozaki, Hiroshi Nishimura, Yoshimasa Shimomura

Patent number: 5198884Abstract: A semiconductor device having a double-layer interconnection with contact portions between first and second metal films covered with at least a silicon nitride film is provided wherein an electromigration characteristic at the contact portions is improved. The improvement is achieved by defining a value obtained by multiplying a thickness of the silicon nitride film by a stress of the nitride film formed at the contact portions is not larger than 2/5 of a value obtained by multiplying a thickness of the silicon nitride film by a stress of the nitride film formed at non-contact portions. By this, the stress exerted on the second metal film is reduced to improve the electromigration life at the contact portions by about one order of magnitude. The first and second metal films are made of Al or Al-based alloys.Type: GrantFiled: March 27, 1991Date of Patent: March 30, 1993Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kohsaku Yano, Tetsuya Ueda, Teruhito Ohnishi, Hiroshi Nishimura

Patent number: 5113865Abstract: In one aspect of correcting phase distortion in an MR imaging system at high speed and with high precision, partial regions having any shapes are established on a complex image reconstruction, linear phase distortion is estimated for every partial region and the phase distortion of the whole image is corrected by use of the estimated phase distortion. In another aspect, a plurality of phase distortion patterns are measured in advance through phantom imaging and stored. The phase distortion pattern is invariable and hence it is not necessary to perform the measurement for each impage processed. Phase distortion included in data acquired through imaging is corrected by representing it as a summation of the plurality of phase distortion patterns with weighting factors.Type: GrantFiled: April 5, 1989Date of Patent: May 19, 1992Assignees: Hitachi Medical Corporation, Hitachi Ltd., Hitachi Microcomputer Engineering Ltd.Inventors: Akira Maeda, Takashi Kasama, Tetsuo Yokoyama, Hiroshi Nishimura

Patent number: 5081672Abstract: An automatic telephone answering machine which is capable of selecting a new outgoing message or an old outgoing message. If a new OGM is unsatisfactory, the operator may retain an old OGM and discard the new OGM. Both a semiconductor memory and a magnetic tape are utilized in switching the OGM's from one to the other. The OGM stored in the semiconductor memory is automatically checked and read out at least once at an end of storage of the OGM in the semiconductor memory, and thereafter the OGM is automatically read out again and transferred to and recorded in an area of a magnetic tape.Type: GrantFiled: May 2, 1990Date of Patent: January 14, 1992Assignee: Sony CorporationInventors: Satoshi Mita, Akira Matsubara, Hiroshi Nishimura, Yoshitomo Nakano

Patent number: 5018888Abstract: A paper tension adjusting device in which one of the tractors with feeding pins changing feeding apertures in the paper is movable widthwise to adjust widthwise paper tension. The desired tension is determined from paper thickness which is in turn determined from the hammer flight time. Lengthwise tension is adjusted by adjusting paper clampers separated from the tractors. The tension is both widthwise and lengthwise directions is determined by optically sensing the positions of the feeding pin with respect to the aperture in which that pin is engaged.Type: GrantFiled: September 11, 1989Date of Patent: May 28, 1991Assignee: Hitachi Koki Co., Ltd.Inventors: Hiroshi Nishimura, Masao Miyasaka, Nobuhiko Itoh, Toshio Hiki, Akira Igarashi

Patent number: 5003152Abstract: In a plasma processing apparatus, a gas to be activated into a plasma is introduced into a plasma formation chamber through a gas introducing pipe. Input microwave energy from a microwave source is also supplied to the plasma formation chamber, so that the introduced gas is activated into the plasma by electron cyclotron resonance. The input microwave energy in a TE mode from the microwave source is received by a tapered waveguide in which a dielectric plate is accommodated, so that at least a part of the input microwave energy is transformed into microwave energy in a TM mode or hybrid mode having an electric field component in the direction of the propagation of the input microwave. Microwave energy in both the modes is introduced into the plasma formation chamber through a microwave introducing window.Type: GrantFiled: October 19, 1988Date of Patent: March 26, 1991Assignee: Nippon Telegraph and Telephone CorporationInventors: Seitaro Matsuo, Hiroshi Nishimura, Mikiho Kiuchi
