Title: Magnetic recording medium
Inventor: KARASHIMA KAZUTO
IPC: G11B5/706
Filed: 1983-03-14
Abstract: PURPOSE:To improve the recording characteristic within a high density range by including metallic magnetic powder having a prescribed characteristic into a magnetic layer and applying orientation so as to attain >=1,000 gauss of vertical residual magnetic flux density. CONSTITUTION:As the metallic magnetic powder, powder having uniaxial anisotropy, needle shape and <=0.4mu of grain diameter is used. When the grain diameter is larger than 0.4mu, the surface smoothness of a magnetic tape is deteriorated and a short wavelength output is deteriorated. The powder like this is coated on the base by an optional means such as roll coater or gravure coating together with a binder resin and the base is dried while being orientated vertically by using a rod magnet with a magnetic field in vertical direction to the base. Then, the vertical residual mangetic flux density of the magnetic layer thus obtained is taken as >=1,000 gauss.

Title: Vibrator holding structure
Inventor: YAMADA KOJI
IPC: F16F15/02
Filed: 1989-02-22
Abstract: PURPOSE:To make it possible to effectively utilize a holding structure for both frequency and phase modulators used with a piezoelectric ceramic vibrator by constituting dead load of the vibrator that supported the cylindrical vibrator in a sealing liquid with a supporter to be almost balanced with buoyancy made by this sealing liquid. CONSTITUTION:The title holding structure consists of a sealed box body 2, a sealing liquid in this box body 2 and a supporter 3 fixed in this box 2, while a cylindrical vibrator 1 is held in the sealing liquid 4 with the supporter 4 in a state of being displaceable in both radial and axial directions, and dead load of the vibrator 1 and buoyancy by the sealing liquid 4 are made so as to be almost balanced with each other. Since the vibrator 1 is gently held by the sealing liquid like this, when it is applied to a holding structure of a piezoe lectric ceramics vibrator, by way of example, any influence to be given to voltage and vibrator characteristics is very little. Accordingly, the holding structure can be effectively utilized for both frequency and phase modulators used with this piezoelectric ceramic vibrator.

Title: Transmission type screen
Inventor: SEKIGUCHI HIROSHI
IPC: G03B21/62
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To obtain a transmission type screen which prevents the formation of double images and decrease in the resolution by providing the light-outgoing face of the sheet with a Fresnel lens sheet having light absorptivity. SOLUTION: A Fresnel lens sheet 11 disposed in the face where light outgoes of the transmission type screen has absorptivity for light, and practically, the sheet base material is colored so that the absorptivity of light is controlled to about 50%. The Fresnel lens sheet 11 is colored by using dyes or pigments by mixing or dispersing in the molding resin. Double images are produced when part of light entering the Fresnel lens sheet 11 is reflected from the face of a Fresnel lens 11a and further reflected from the back face of a Fresnel lens 11b and then the light outgoes. Therefore, the optical path length (shown as a double dotted chain line) L2 of the double image is three times or more as long as the optical length L1 in the Fresnel lens sheet 11 for a normal image.  Thus, by controlling the absorptivity of the sheet to 50%, the light of the double image is decreased by (0.5)3=0.125, namely, about 1/10, and the double image is hardly seen.

Title: Gradation display of image output apparatus
Inventor: YAMADA KUNIO
IPC: G06T5/00
Filed: 1988-02-25
Abstract: PURPOSE:To stabilize the reproduction of gradation and thereby improve image quality by limiting the number of protruding parts which are difficult to reproduce accurately among micropixels forming halftone dots and arranging the protruding part in a direction where it can be easily reproduced stably. CONSTITUTION:An image is subdivided into pixels of a minute area, the pixel is further subdivided into micropixels of a more minute area, and halftone dots (P0-P16) are formed by the micropixels colored in the pixel. Then a gradation is displayed by the proportion of the colored micropixels to the total micropixels. The halftone dots P0-P16 are always formed with a single group of connected micropixels, and the colored micropixels are decided in response to each gradation. When each gradation level is displayed, the colored micropixels which form a single halftone dot are specified so that the number of protruding parts formed by a single colored micropixels is limited to at most one. Consequently, a protruding part consisting of a single colored micropixel is arranged in a direction where it can be easily reproduced stably, and thus the reproduction of a gradation becomes stable.
