Title: Waveguide type isolator independent of polarization
Inventor: KATO YUJIRO
IPC: G02B27/28
Filed: 1993-04-21
Abstract: PURPOSE:To nearly double a forward/backward ratio for a usual type and to remarkably reduce an insertion loss by arranging a waveguide type polarization beam splitter on the incident side and the outgoing side of a specified Faraday rotator. CONSTITUTION:The Faraday rotator is constituted by connecting magnetic garnet crystal waveguides, that is, waveguide type Faraday rotators 1 in series by interposing thin film type polarizers 5, 6 between the rotators 1, and the waveguide type polarizing beam splitters (PBS) 3, 4 are arranged on the incident side and the outgoing side to the rotator as the polarizers. The rotator 1 is the Faraday rotator rotating a polarization plane by 45 deg. unreciprocally, and is formed by machining a garnet crystal film on a crystal substrate. The polarizers 5, 6 are arranged so that respective passable polarization planes intersectt orthogonally to be stuck to the rotator 1. The PBSs 3, 4 are pattern formed on the crystal substrate. The performance of the PBS 3 as the polarizer is nearly 30dB, and the loss is approximately 0.5dB. Further, a reflection return beam is quenched by 30dB.

Title: Deflector device for movable roof type vehicle
Inventor: IMAI HIROSHI
IPC: B60J7/22
Filed: 1989-04-14
Abstract: PURPOSE:To prevent reduction of effective aperture area of a roof and spoilage of beauty of the inside in a vehicle by attaching a deflector to front and rear arms, which are guided by a guide rail at their lower ends respectively and forced to be folded like V-shaped through a spring arranged between their upper ends, and by providing a means for moving the front arm. CONSTITUTION:When a lid is moved forwards through a driving wire not shown in the figure, a front end of a pushing member 11 comes into contacts with a rear face of a slider 8, and moves the slider 8 forwards against a spring 9. In this way, the slider 8 pushes a guide member 21 of the front arm 2 and moves the guide member 21 forwards against a spring 7. Consequently, the front arm 2 and the rear arm 3 do relative rotation about an axis 6 and lie flat. This makes a deflector 1 lie down also. For this reason, the deflector 1 is received above a frame B in a periphery of a roof. By using this constitution, reduction of effective aperture area of a roof and beauty of an inside of a vehicle can be prevented.

Title: Disk clamping mechanism
Inventor: KATAOKA MASANORI
IPC: G11B17/028
Filed: 1989-04-14
Abstract: PURPOSE:To obtain an extremely thin clamping mechanism by sticking a ring on a disk medium and fitting a clamper to the outside of the ring to position the clamper. CONSTITUTION:The main body of a clamper 5 can turn separately with the effect of a bearing 6. One of both ends of a spring 7 is engaged to a spring holder stage 22 with the other end engaged to a spring holding plate 24 respectively. The plate 24 aligns the upper end position of the spring 7. The rings 25 have the diameters slightly smaller than the inner diameter of the pressing surface of the clamper 5 and are stuck on both sides of a disk medium 4. A slanting surface 25a is formed at the entire outer periphery of each ring 25. The clamper 5 is fitted to the outside of the ring 25 and presses the medium 4. Consequently, the approximate coincidence is obtained between a spindle motor 1 and the axial line of the clamper 5. Thus the clamper 5 does not swing despite the rotation of the medium 4. Furthermore no extension of a center shaft 3 of the motor 1 is required and therefore the distance between the upper surface of a turntable 2 and the tip of the shaft 3 can be reduced. Thus a thin disk clamping mechanism is obtained.

Title: Probe needle and probe card
Inventor: HONDA SHINJI
IPC: G01R1/073
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To obtain a probe needle in which passivation cracks hardly occur even in miniaturization of the size of a pad, by forming the cross-sectional shape of the needle tip part of a probe needle for testing IC wafer characteristics in the shape of a long ellipse, with the short axis in the sliding direction and the long axis in a vertical direction with respect to the direction of sliding. SOLUTION: In the cross-sectional shape of the needle tip part of a probe needle, the diameter 4 in the direction of sliding is a breadth of approximately 10 μ, and the diameter 5 in a vertical direction with respect to the direction of sliding is a length of approximately 40 μ. The diameter 4 in the direction sliding is one-half of the diameter 2 (approximately 20 μ) of a circular cross section, and the diameter 5 in a vertical direction with respect to the sliding direction is two times as long as the diameter 2 of the circular cross section. By this, the diameter in the direction of sliding becomes smaller by approximately 10 μ, and the length of the track of the probe needle in the direction of sliding becomes smaller by approximately 10 μas well.  Therefore, the margin of the IC pad opening part in the direction of sliding is secured to reduce problems of passivation cracks due to the miniaturization of the size of the IC pad. In addition, as the contact area between the needle tip part and the IC pad has no difference from a proceeding one, problems do not occurs.

Abstract: PURPOSE:To prevent the device stated in the title from being enlarged by arranging magnetic shield materials at almost regular intervals between the magnetic pole of a condensor lens and a toroidal coil which materials have their longitudinal direction parallel to the direction of the axis of an electronic optical system. CONSTITUTION:Since the upper side magnetic pole 13a of a condensor lens 13 is located on the outside of a toroidal coil 14, a magnetic field 20a unnecessary for deflection is formed outside the coil 14. A magnetic shield 190 comprises a plastic cylinder 190a located around the coil 14 and magnetic shield materials 19a fixed at regular intervals around the cylinder in such a manner that their longitudinal direction is parallel to the axis of an electronic optical system. A magnetic shield 191 is formed by providing plural ring-shaped magnetic shield materials 191a of different diameters coaxially with the axis of the optical system, and the shield 191 prevents a leakage magnetic field from the coil 14 from passing through the upper pole 13a of the condensor lens as indicated by the dotted line in the figure. That driving current of the toroidal coil of the electromagnetic deflector which will not generate hysteresis in the magnetic field of the electromagnetic deflector is thereby reduced to small amount.
