Title: Polarization separation element and optical head using the element
Inventor: FUNATO HIROYOSHI
IPC: G11B7/135
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To reduce a count of processes and a unit price, by mounting an anisotropic film showing different indices of refraction as a periodic lattice to different vibration faces of an incident light on a transparent substrate, coating an isotropic overcoat layer thereon, and separating a polarization light orthogonal to the incident light to a O-order light and a diffraction light. SOLUTION: A polarization separation element 1 has an anisotropic film 3 of a structure of a periodic lattive formed on a transparent substrate 2 of glass, plastic, etc. An isotropic overcoat layer 4 is coated over the anisotropic film 3. The anisotropic film 3 shows anisotropy of different indices of refraction to a light vibrating in a direction of a paper face and a light vibrating perpendicularly to the paper face. Supposing that a light entering the polarization separation element 1 has vibration components in two directions, i.e., the direction of the paper face and the direction perpendicular to the paper face, the light of the vibration component in the direction of the paper face runs straight as a O-order light. The light of the vibration component in the perpendicular direction to the paper face is diffracted as a ± first-order light.  The polarization separation element thus acts to change an advancement direction because of the polarization.

Title: Mountain-shaped tape cutter egde shape
Inventor: YOTSUKA HIROSHI
IPC: B26D1/02
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To eliminate side deviation and very lightly perform a cutting by making the center part of an edge of a tape cutter higher than both end parts of the edge. SOLUTION: Wrinkles at the center part of a tape and cut remainings on one side are generated on occasion because a horizontal inclination of an edge shape is generated when a tape is going to be cut by being pulled, horizontally and averagely being pushed on an edge shape because an edge part is horizontal in a conventional tape cutter. Therefore, a center part 3 of a cutting edge 1 is constituted to be a mountain shape by making the center part 3 higher than both the tip parts 2 of the cutting edge 1 to compensate this defect. Because the center part of the tape can be cut at the center part 3 of the cutting edge 1 at first by this constitution, side deviation is eliminated and the tape can be very lightly cut.

Title: Address conversion controlling system
Inventor: TONE HIROSADA
IPC: G06F12/10
Filed: 1982-06-30
Abstract: PURPOSE:To prevent undesirable rewriting of address conversion buffer by writing the result of address conversion on a port register instead of writing on an address conversion buffer that stores a memory protection key at the time of nonstorage protection check mode. CONSTITUTION:When an address conversion buffer 2 in which a memory protection key KEY is referred through comparators 3, 4 and effective address set in an effective address register 1 is not set in an address conversion mechanism 8, effective address is converted to physical address and stored in the buffer 2. On the other hand, at the time of nonstorage protection check mode, physical address extracted from the mechanism 8 when setting is not made is not stored in the buffer 2, but written on a port regiser 7 and transferred to a result register 6. By this configuration, contents of address conversion buffer are not rewritten undesirably, and effective address conversion can be carried out.
