Title: Polarizing plate with wide visual field
Inventor: SAIKI YUJI
IPC: B29K1/00
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To obtain a polarizing layer which can enlarge a well-visible region in a liquid crystal display device. SOLUTION: A polarizing plate with wide visual field has a double refractive layer A31 having <=300μm phase difference in a thickness direction defined by a formula: (ns -nz )d and <=20nm intra-plane phase difference defined by a formula: (ns -nf )d and a double refractive layer B32 having 50 to 200nm intra-plane phase difference and 0.8 to 3.5Nz defined by a formula: (ns -nz )/(ns -nf ) at one side of the polarizing layer 1 (in the formulas, ns is a refractive index in a lagging axis direction, nz is a refractive index in a leading axis direction, nz is a refractive index in a thickness direction and (d) is a layer thickness). Further, a lagging axis of the double refractive layer B32 and a transmission axis of the polarizing layer 1 are in relation of being parallel or orthogonal to each other.  Therefore, degrading of brightness and contrast can be prevented in a front surface direction perpendicular to the polarizing layer surface, state change of linear polarized light by double refractivity of a liquid crystal cell is compensated, a well-visible region which has no color change such as coloring and no gradation inversion and is excellent in contrast and brightness can be enlarged and the liquid crystal display device having the wide visible angle range can be obtained.

Title: Laser recorder
Inventor: BUREA IAN FUINKERUSHIYUTAIN
IPC: G11B7/125
Filed: 1993-12-14
Abstract: PURPOSE: To minimize laser feedback during data recording by providing a controlling means for enabling the establishment of a state a little out of focus selected during the data recording operation. CONSTITUTION: An optical disk 10 reflects a beam supplied from a laser 11 through an objective condenser lens 19 and an optical system 300. The optical system 300 changes the direction of a reflected light, and directs it along an optical path 22 to a focus detector 304. The focus detector 304 supplies a focal error signal to a condensing circuit 23'. The circuit 23' is connected to a focal coil 303 so that a proper focus control signal for activating the movement of a lens carriage 32 can be supplied. In this constitution, it is preferable that a focus 330 is not directly abutted to the reaction layer of the optical disk 10 by shifting a little the focus of the lens during a writing processing. Therefore, the focus servo of the circuit 23' can establish and hold the focus 330 at a position out of focus relatively to the surface of the optical disk 10.

Title: Sensing method for foreign matter on semiconductor wafer
Inventor: SAWA TOSHIO
IPC: G01N27/02
Filed: 1990-11-21
Abstract: PURPOSE:To sense defect of wafer in an early stage by judging the degree of cleanliness in the washing process for semiconductor wafer by means of in-line measurement. CONSTITUTION:A semiconductor wafer 1 is inserted between electrodes 2, 3 and placed on the former 2, and either the wafer is put in contact with the latter 3 or a space is provided. Externally, for example from a frequency response device 4, a high frequency voltage is impressed to the gap between these two electrodes 2, 3. Therein the wafer 1 and impurities have different electric resistances and capacitances, and therefore, their components are separately measured by varying the frequency of the impressed voltage. This electric resistance is proportioned to the thickness of impurities and is in inverted proportion to the area, while the capacitance is in inverted proportion to the length and is proportioned to the area. Accordingly changes in the thickness and area of the impurities become apparent as changes in the electric resistance and the capacitance, which are thus measured.

Filed: 1990-11-21
Abstract: PURPOSE:To improve recording density by making a core on the trailing side higher than that on the leading side in the saturation magnetic flux density of a thin-film magnetic head in the transport direction of a medium. CONSTITUTION:When the saturation magnetic flux density of a core 1 on the trailing side of a thin-film magnetic head is made higher than that of a core 2 on the leading side in the transport direction of a recording medium 6, the thin-film magnetic head, in which the magnetic saturation of the core 1 is inhibited by the differential effect of saturation magnetic flux density, the lowering of the reproduction output with the increase of coersive force is reduced sufficiently, recording density characteristics are improved and recording reproducing ability sufficient even for a high coercive force medium is obtained, is prepared, and a magnetic disk device suitable for high density recording is manufactured. Since the high saturation magnetic flux density of a core material is required for recording reproduction enough to the high coercive force medium, saturation magnetic flux density on the leading side having low saturation magnetic flux density must be equal to or higher than at least a normal type core.

Filed: 1995-12-01
Abstract: PURPOSE: To reduce weight of a tire without injuring its physical characteristic by reducing the thickness of a mutually twisted yarn in accordance with the thickness calculated from the required tensile strength and compensating the loss of the tensile strength by means of reducing the twisted quantity to less than that calculated from the fatigue degree. CONSTITUTION: The thickness, or in other words, the mass of a yarn 2 is reduced in accordance with the thickness or the mass calculated from the required tensile strength and the loss of the tensile strength yielded therefor is compensated by simultaneously reducing the twisted quantity to a quantity less than that calculated from the required fatigue degree. When the arrangement of the yarn 2 and the number of cords per ply in a twisted thread 1, or in other words, a cord are the same due to the reduction of the yarn 2 thickness, weight of the rubber adhered ply reduces. A rubber layer 3 arranged in the upper part and the lower part of a textile ply for isolating from and joining with an adjoining structure body is proportionately reduced and weight of an elastic rubber material is reduced by the reduction of net weight of the cord and making it a thin cord.
