  • Patent number: 6693750
    Abstract: A zoom lens system with superior optical performance capable of carrying out vibration reduction correction. The zoom lens system includes, in order from an object, a first lens group G1 having positive refractive power, a second lens group G2 having negative refractive power, a third lens group G3 having positive refractive power, and a fourth lens group G4 having positive refractive power. Zooming is carried out by moving the second lens group G2 and the third lens group G3 along the optical axis. The fourth lens group G4 is composed of, in order from the object, a front group G4F having positive refractive power, a middle group G4M having negative refractive power, and a rear group G4R having positive refractive power. An imaging position is varied by shifting the middle group G4M in the direction perpendicular to the optical axis resulting in vibration reduction correction.

  • Publication number: 20040021863
    Abstract: Light from a light source 10 is linearly polarized by a polarizer 11. Then it propagates via a half-mirror 12 almost parallel to the normal to a reflective liquid-crystal panel 13 and falls on the reflective liquid-crystal panel 13. The reflected light reflected by the reflective liquid-crystal panel 13 is received by a detector 15 via the half-mirror 12 and an analyzer 14. In this state, the reflective liquid-crystal panel 13 is rotated about an axis almost parallel to the normal to the reflective liquid-crystal panel 13 and an angle (extinction angle) at which the output signal of detector 15 reaches minimum is measured. Then, the gap of the reflective liquid-crystal panel 13 is detected based on the measured extinction angle.

  • Patent number: 6681478
    Abstract: When any of facilities of a film producing and packaging system suffers a failure, a film processing controller shuts off the film producing and packaging system. The operator repairs a failing facility and manually discharges a length of an elongate film which may possibly be defective. After the failing facility is repaired, the film processing controller is restarted to operate the film producing and packaging system, which then automatically discharges a length of the elongate film corresponding to a preset number of sized films. It is possible to easily and quickly discard a portion of the elongate film which has been made defective by the facility failure.

  • Patent number: 6658717
    Abstract: Firstly, using a cutting tool 30, connecting ribs 13 are cut off from the end face of a duplex pipe 10 which is held with an outer pipe 11 chucked (rib cutting step). Next, the duplex pipe 10 is cut at and from the end face of the duplex pipe 10 up to the portion thereof corresponding to the exposed length of the inner pipe 12 to thereby form a slit 21 in the outer pipe 11 and connecting ribs 13 (slit forming step) The cutting tool 30 comprises a guide hole 31 into which the inner pipe 12 can be inserted while guiding the inner pipe outer peripheral surface 12a, a cutting device 32 for cutting the connecting ribs 13, and a guide pin 33 which is disposed in the guide hole 31 and can be inserted into the inner pipe 12 while guiding the inner pipe inner peripheral surface 12b.

  • Publication number: 20030112563
    Abstract: A head substrate and a protective substrate are formed of an electrostatic-discharge resistant conductive material having an electrical resistivity of 102 to 1010 &OHgr;cm. These substrates are electrically connected to a base metal through the use of conductive paste and are set to a ground potential via the base metal and a rotating drum. This suppresses a discharge current flowing through an MR element when an electrostatically charged substance touches or approaches a magnetic reproducing head, a terminal, a conducting wire, etc. to generate an electrostatic discharge. The magnetic reproducing head including an MR element and the like is prevented against an electrostatic discharge damage. It is possible to provide the magnetic reproducing head, a head drum apparatus, and a magnetic recording-reproducing apparatus which can highly effectively prevent an electrostatic discharge damage.

  • Publication number: 20030071995
    Abstract: An apparatus for detecting a pretilt angle is comprised of a light source 1, a polarizer 2, a liquid-crystal cell 3, a quarter-wave plate 4, an analyzer 5, a photodetector 6, and a processing device. The processing device receives from the photodetector transmitted light intensities of light that is transmitted through the liquid-crystal cell 3 at a plurality of light incident angles. The processing device calculates Stokes parameters corresponding to the plurality of light incident angles based upon the transmitted light intensity corresponding to the plurality of light incident angles. Furthermore, an apparent retardation corresponding to the plurality of light incident angles is determined based upon the Stokes parameters corresponding to the plurality of light incident angles. The pretilt angle of the liquid-crystal cell 3 is determined based upon the determined apparent retardation corresponding to the plurality of light incident angles.
