Title: Polarizer
Inventor: EZAKI SANPEI
IPC: G02B1/08
Filed: 1994-02-07
Abstract: PURPOSE:To suppress degradation in degree of polarization as far as possible even under a thermal stress or dynamical external stress by decreasing the photoelastic constants of transparent substrates to substantially zero. CONSTITUTION:This polarizer is constituted by forming >=2 layers thin films varying in refractive index from each other on the surfaces of transparent substrates 7a, 7b and selects and emits light 4, 5 having specific vibration directions by utilizing the dependency of the reflectivity and transmittance of rays 3 at the boundary faces of the respective thin films on polarization. The photoelastic constants of the transparent substrates 7a, 7b are decreased to substantially zero. The term 'the photoelastic constants are substantially zero' refers to about a value at which the influence to be exerted on reading out light 9 by an optical path difference based on the optical anisotropy of the transparent substrates 7a, 7b is negligible. As an example, the photoelastic constants suffice if the value thereof is in a range from -0.1 to 0.1 [10<-8>cm<2>]/Nl for light of a wavelength 500 to 650nm. The transparent substrates 7a, 7b have the substantial optical anisotropy and the optical path difference is substantially not generated in the light propagating in the transparent substrates 7a, 7b even if the thermal stress and dynamic external stress are generated in the transparent substrates 7a, 7b.

Title: Epoxy resin composition
Inventor: ISOBE ASAO
IPC: C08G59/68
Filed: 1981-01-30
Abstract: PURPOSE: The titled composition which, when irradiated with ultraviolet rays, does not produce an uncured lower layer part, containing a specified epoxy resin, an onium salt of Group VIa element and a boron trifluoride/amine salt.  
     CONSTITUTION: The titled composition contains a nitrogen-free epoxy resin (A) having at least two epoxy groups in the molecule (e.g., bisphenol/epichlorohydrin type epoxy resin), an onium salt (B) of a Group VIa element (e.g., sulfonium salt of a Group Va Lewis acid, especially, triphenylsulfonium fluoroantimonate and boron trifluoride/amine salt (C) (e.g., boron trifluoride/monoethylamine). This epoxy resin composition, because of the presence of component B, cures upon irradiation with ultraviolet rays, and the part left uncured by this irradiation can be cured by heat in the presence of component C. Accordingly, this can solve a problem incidental to conventional ultraviolet ray curing, that is, a problem of uncure of parts shadowed from ultraviolet ray irradiation and of lower layer parts.

Title: Magneto-optical medium and recording and reproducing device
Inventor: KUREBAYASHI MASAAKI
IPC: G11B11/105
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To efficiently record and reproduce by using a medium in which an intraplane magnetization film is partly used, applying signals on a recording magnetic head and detecting magneto-optical signals corresponding to the applied signals when magneto-optical signals are to be reproduced, and adjusting the position of the head to obtain the max. signal amplitude. SOLUTION: This disk has an interference film 2 formed on a polycarbonate substrate 1, and a magnetic film 3 formed on the film 2. The interference film 2 consists of silicon nitride and controls the reflectance by an optical interference effect to increase the Kerr rotation angle of the magnetic film. In the hysteresis characteristics of the Kerr rotation angle with the axis of abscissa representing the external magnetic field Hex and the vertical axis representing the Kerr rotation angle θk, it is shown that the magnetization direction easily changes with an external magnetic field applied and the Kerr rotation also changes with that. Namely, when the external magnetic field changes from Ha to Hb, the Kerr rotation angle changes from θa to θp. Therefore, positioning of a magnetic head can be performed in a reproducing state, which reduces the adjusting time.
