Title: Optical pickup device
Inventor: KUME HIDEHIRO
IPC: G11B7/13
Filed: 1988-10-29
Abstract: PURPOSE:To correct the asymmetry between a beam spot formed in the focus deviation direction and a recording track and to improve the correlation between the focus deviation value and the displacements of various characteristics of an optical pickup device by setting a semiconductor laser element so as to tilt the meridional surface of the light beam projected on an optical disk in the tangent direction of the recording track of the optical disk by a prescribed angle. CONSTITUTION:The light beam radiated from a light transmission/reception composite element 3 is made incident on an objective lens and then projected on a signal recording surface of an optical disk 101. In the case, the element 3 is set so that the meridional surface of the light beam is set by a prescribed angle, i.e., about 45 deg. to the tangent direction of a recording track of the disk 101. Thus it is possible to correct the asymmetricalness defined on the basis of the tangent of a beam spot produced on the disk 101 according to the focus deviation direction. As a result, the characteristic of an optical pickup device are improved to the focus deviation.

Title: Ink jet recorder
Inventor: YAEGASHI HISAO
IPC: B41J2/01
Filed: 1993-11-02
Abstract: PURPOSE:To conduct waste ink generated by recovery operation (action) efficiently cirtainly to the whole of an waste ink absorbing material to be held without clogging. CONSTITUTION:In an ink jet recorder, a waste ink absorbing material 28 before inserting into a member to be covered is a truncated conical isotropic polyurethane foam absorbing material. Since a diameter of the waste ink absorbing material 28 is the larger for the further downstream side, ink absorptivity of the waste ink absorbing material 28 is low on a side wherein waste ink flows in from a recovery device and high on its opposite side. That is, by inserting the waste ink absorbing material 28 into the cylindrical member to be covered 27, the ink absorbing material 28 becomes cylindrical, and the capillary thinner state can be made towards the further downstream side. Therefore, the waste ink made to flow in from an upstream side is sent to the downstream side according to an inclination of capillary force.

Title: Optical fiber coil
Inventor: OGURA KUNIO
IPC: G02B6/00
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To obtain an optical fiber coil which can be formed by only naturally winding an optical fiber in a coil-like state and is small in polarization dispersion by winding a coated single-mode optical fiber in which the thickness deviation in the resin coating of the fiber changes in the length direction around a reel. SOLUTION: When a dispersion-compensating optical fiber 3 is drawn with a fiber drawing device 10, the fiber 3 is coated with a first-layer resin by means of a die 12 and the resin 13 is cured in a resin curing oven 13. Then a dispersion compensating single-mode coated optical fiber 1 is obtained by generating a thickness deviation in the second coating by periodically vibrating a die 14 at the time of coating the fiber 3 with a second-layer resin and curing the resin in a resin curing oven 15 and the fiber 1 is wound around a reel. Since the thickness deviation in the coating of the fiber 1 changes in the length direction, the directions of stresses caused by side pressures applied to the fiber 1 and bends are averaged and double refraction hardly occurs. Therefore, an optical fiber coil which is small in polarization dispersion is obtained.

Title: Tape carrier for tab and chemical polishing method thereof
Inventor: CHIBA TSUKASA
IPC: H01L21/60
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To obtain specified lead strength so as to ensure required thickness of a Cu foil after removal of an anticorrosive film in punching holes. SOLUTION: The tape carrier for TAB comprises a Cu foil 1 having an anticorrosive film at one side and a polyimide film 4 having previously formed punching holes 5. The film 4 is coated with adhesive 3, and bonded to one anticorrosive side of the Cu foil 1. The thickness difference between the Cu foil in the punching holes 5 after removal of the anticorrosive film 2 from these holes and Cu foil at other parts than the holes is within 2μm enough to minimize the Cu foil thickness difference. This prevents the lead strength in the punching holes from reducing and hence from being bent or deformed.
