摘要:
There is provided an optical information recording medium which can meet opposite requirements of enhancement in ink absorption and fixation properties of an image forming layer and suppression and prevention of solid attachment of a printed portion, which has excellent printability to obtain high image quality and an excellent holding property of the printed portion, and which little makes the solid attachment on the printed surface layer occur. At this time, a thick layer can be formed even by the use of a coating solution for the image forming layer. The optical information recording medium has the image forming layer on various layers stacked on a surface of a light transmitting substrate and optically readable signals are recorded or can be recorded therein by the use of laser beams incident on the other surface of the light transmitting substrate, wherein the image forming layer includes an ink absorbing porous layer made of a resin layer containing vapor inorganic particles. A hydrophobic portion is formed in a portion beside the porous layer on the surface of a layer adjacent to the porous layer. An anchor layer is disposed under the porous layer.

摘要:
First pumping threads are formed on an inner circumferential surface of the seal lip portion of an elastomer lip member. The first pumping threads generate a pumping action in a leakage direction when a shaft rotates. A first resin lip member is arranged at a rear side of the elastomer lip member. Second pumping threads generate a pumping action in a direction opposite to the leakage direction when the shaft rotates. The second pumping threads are formed from an inner circumferential surface of a seal lip portion of the first resin lip member to a rear portion of a bent portion thereof. A second resin lip member is arranged at a rear side of the first resin lip member and has a surface sliding on the shaft, which is formed smoothly.

A piezoelectric substrate includes vibrating arms, a base portion to which one end portion of each vibrating arm is connected, spindle portions formed in the other end portion of each vibrating arm, formed to have a large width, and having first groove portions formed therein, and second groove portions that are formed along the resonator center line of each vibrating arm, and flexure-torsional combined resonator is excited. A piezoelectric resonator element has flexural resonator of flexure-torsional combined resonator that is excited as its principal resonator and sets the cutting angle of the piezoelectric substrate, the widths and the depths of the first groove portion and the second groove portion, and the thickness of the vibrating arm such that the frequency-temperature characteristics represent third-order characteristics with respect to the temperature.
摘要:
A lip type seal (3A) has an annular casing (31), a plurality of seal lips (32, 34) and a rear surface support ring (35) arranged at the rear side. The casing (31) is installed to an inner circumferential surface of a seal installation part (1a) of a shaft hole housing (1) of an equipment through a main gasket (36) made of rubber state elastic material. An inner circumferential part of the seal lips (32, 34) is closely contacted with an outer circumferential surface of a rotary shaft (2). A sub-gasket (41) made of a material having a CO2 transmission coefficient being smaller than that of rubber material is interposed between the rear surface support ring (35) and the shaft hole housing (1).
摘要:
An optical information mediumis made up of a transparent substrate, on which are formed a dye recording layer of at least one dyestuff, a reflective layer of metal, and a protective layer in sequence, wherein said protective layer is formed from a plurality layers of resin which are formed sequentially. Further, the reflective layer is made of silver, and the dye recording layer is made of a material which does not contain iodine ion. The protective layer contains a material for trapping molecules and/or ions which corrode the reflective layer. For instance, a metal powder or porous pigment is contained in the protective layer, which is active on or absorbs the molecules and/or ions corroding the reflective layer.
