Title: Square root extraction arithmetic unit
Inventor: KISHINO MASAHIKO
IPC: G06F7/552
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To efficiently execute fast extraction of square root processing with the addition of a relatively small scale hardware by dividing a square number into plural parts and executing processing extracting partial square root through parallel processing in each part partially several times. SOLUTION: A number to be extracted is set to a number to be extracted part 61. For instance, when the number to be extracted is 16 bits, the number to be extracted is delimited into 4 bits each, and a partial square root calculating device which has two subtracting devices 64 to 67 that are serially connected repeats processing that calculates a 2-bit partial square root through parallel processing to each 4-bit data four times. The square root of numbers to be extracted is calculated by synthesizing partial square roots which are calculated in each processing. Thus, for example, two subtracting devices are needed to double an arithmetic speed, and it is possible to accomplish the improvement of an equivalent arithmetic speed with increase of fewer hardware scales in comparison with a conventional square root extraction of arithmetic unit.

Title: Optical modulator
Inventor: SAKATA HAJIME
IPC: G02B5/30
Filed: 1985-03-05
Abstract: PURPOSE:To obtain an optical converter provided with high light utilizing efficiency for incident light having a polarization characteristic by forming a grating of the boundary face between the 1st material having optical isotropy and the 2nd material which permits the control of the two states; optical anisotropy and optical isotropy. CONSTITUTION:The optical state variable material 1 exhibits the optical anisotropy in a static state and the optical axis thereof faces the groove direction of the grating. Polarization components 6 and 6' intersecting orthogonally with each other of the incident light 5 sense the grating consisting of refractive indices no and ng, ne and ng. The material changes to the isotropic material and the polarization components sense the grating consisting of the refractive indices ni and ng when heat is exerted to the material 1 by a transparent heater 3 so as to be heated up to the critical temp. or above. Zero order transmitted and diffracted light 8 is not generated in the static state if prescribed relations are set among the refractive indices ne, no, ni of the material 1, the refractive index ng of the material 2 and the wavelength lambdao of the incident light. The incident light 5 is fully transmitted through the grating and exits therefrom as zero order transmitted and diffracted light 8 when the state of the material 1 is changed to the optical isotropy by the heater 3.

Title: Blanket for offset printing
Inventor: IWASAKI YOSHIO
IPC: B41N10/02
Filed: 1988-02-26
Abstract: PURPOSE:To eliminate the need for a complicated adjustment of damaging water and prevent a reverse trapping phenomenon or contamination of non- image areas with an ink from occurring, by composing a surface printing layer of a hydrophilic oil-resistant material. CONSTITUTION:A surface printing layer is a hydrophilic surface printing layer composed of an oil-resistant material having a surface tension of 35-60mN/m. With the surface tension of the surface printing layer set in the range, it is possible to prevent a reverse trapping phenomenon or contamination of non- image areas with an ink from occurring. The surface printing layer is formed from an oil-resistant material (e.g., a synthetic rubber or polyurethane) and various additives, e.g., a crosslinking agent, a filler or a plasticizer. Hydrophilicity with a surface tension of 35-60mN/m can be imparted to the surface printing layer by, for example, a method wherein a polymer having a hydrophilic group is used as a polymer component of the layer, or a method wherein a modifier, an activator or the like is added to the polymer components in a hardening reaction of the layer. Since the surface printing layer is preliminarily provided with a predetermined degree of hydrophilicity, a uniform water film can be formed even by use of a small amount of dampening water.
