Title: Polarizer and its manufacture
Inventor: ISHIKAWA SHINJI
IPC: G02B6/024
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To provide a polarizer which is easily designed and manufactured and has superior polarizing characteristics and its manufacture. SOLUTION: When the core mode light propagated in a polarization maintaining optical fiber 10 reaches the area 13 where a long-period grating is formed, a specific-azimuth polarized component of the core mode light has loss owing to the coupling with clad mode light and is cut off by the long-period grating. Other-azimuth polarized components, on the other hand, are transmitted through the long-period grating with low loss without being coupled with the clad mode light.

Title: Card delivery device
Inventor: SUKEGAWA KAORU
IPC: G06K13/14
Filed: 1993-08-19
Abstract: PURPOSE:To properly deliver cards one by one even when two cards strongly adhere to each other by forming a step on a feed roller along a direction orthogonal with a rotating direction and, then, positioning the upper surface of the feed roller lower than the upper surface of an idle roller. CONSTITUTION:A stepped roller 3C has a step 3C' all around and the upper surface of a pair of rollers 3a and 3b forming a feed roller 3 is positioned lower than the upper surface of idle rollers 2a and 2b by the prescribed distance.

Title: Method of garbage collection
Inventor: SHINAGAWA AKIO
IPC: G06F9/44
Filed: 1982-12-27
Abstract: PURPOSE:To enable simultaneous access of plural member nodes and speed up garbage collection by dividing a memory and providing an address register that can access each domain simultaneously. CONSTITUTION:The leftthand side part (r0, a0) of the register 1 indicates address of lefthand member node, and the righthand side part (r1, a1) indicates address of righthand member node. Whether this address indicates a domain I 3 or domain II 4 is controlled by a signal switching circuit 2. In this case, if a member node is read out newly, the leftthand member node is stacked on a stack 7. Similar procedure is repeated, and when a stage in which lefthand member node read out from the memory is a terminal node is arrived at, a value drawn out from the stack 7 is set to the register 1. Thus, simultaneous access of plural member nodes is made possible and garbage collection can be speed up.
