Title: Optical isolator
Inventor: YANAGAWA HISAHARU
IPC: G02B27/28
Filed: 1990-02-16
Abstract: PURPOSE:To obtain the optical isolator which has no dependency on polarization by forming respective polarizers of the polarizers which intersect orthogonally with each other in the pass polarization directions thereof. CONSTITUTION:Polarization separator/couplers 4a, 4b can separate or couple the two polarized light components intersecting orthogonally with each other. The two polarized components are coupled to one optical path and are emitted after the incident polarized light component on the polarization separator/coupler 4b passes the polarization separator/coupler 4b when the crystal direction of the polarization separator/coupler 4b is assumed to rotate by 135 deg. from the crystal direction of the polarization separator/coupler 4a. On the other hand, the incident reflected light on the main optical path is so separated as to be reversed in the polarization separator/coupler 4b and propagates backward in the branching optical paths 3a, 3b. The optical isolator has the characteristic not relying on the polarization in this way and can be inserted between optical fibers of a non-polarization maintaining type.

Title: Cassette
Inventor: YODA KUNIKAZU
IPC: B65D85/00
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To improve light emitting intensity and light emitting time of a luminous ink layer so as to shorten the discriminating time by providing a light reflecting layer to a part to observe a cassette and then forming the luminous ink layer on this light reflecting layer. SOLUTION: A reflecting layer 3 is formed on the surface of a supporting member 2. A luminous layer 1 is further formed on the reflecting layer 3. The luminous layer can be formed by printing available ink in which stimulable particle is dispersed. The light from the laminated body including the luminous ink is reflected by the reflecting layer 3 at the rear surface side. Therefore, light is mainly released to the external side. Accordingly, light intensity in the dark area is doubled in maximum and light emission can be continued for a longer period in comparison with the case where the reflecting layer is not used. Thereby, not only the light can be recognized easily in the dark area but also the time to read the characters entered in the label can be extended for a longer period.

Abstract: PURPOSE:To reduce an installation space, to increase the work efficiency and to improve convenience for use. CONSTITUTION:At the time of placing materials to be counted thrown in from a counting and stacking device on stacked materials on a transport conveyer 40, a difference in levels between both side edges of stacked materials and counted materials is detected and the counted materials are reversed if necessary by a reversing mechanism 20 so as to improve the stability of stacked materials and stacked materials are stably stopped and transported by front and rear stoppers 53, 63. Accordingly, a bucket conveyer is no more required and it is not necessary to push out stacked materials from a bucket in the direction intersecting perpendicularly to the transport direction, so that a transport line can be made rectilinear without bending in the right-angled direction. Furthermore, the capacity of the line may not be limited by the capacity of the pusher. Further, the amount of the stacked materials on the transport conveyer 40 is reduced and the general control data for controlling the stacked materials are decreased so as to facilitate processing for the stacked materials.
