摘要:
A DNA encoding a cell surface polypeptide of Porphyromonas gingivalis, and a recombinant DNA being a DNA having integrated said DNA thereinto. The cell surface polypeptide of the periodontopathic organism useful for prophylaxis and diagnosis of periodontal diseases can be obtained in a large amount by a microorganism containing the recombinant DNA wherein the DNA was integrated.

摘要:
A composition containing magnetic metal oxide ultrafine particles, which comprises an aqueous sol of a complex of the magnetic metal oxide ultrafine particles with a polysaccharide, a polysaccharide derivative and/or a protein; and an organic monocarboxylic acid. The composition is free of side effects such as platelet aggregation, is safe for use with living bodies, and, in the case of intravascular administration, has no harmful effects on living bodies, and is useful in fields such as medicine and diagnostic drugs.
摘要:
An oxidized complex comprising a water-soluble carboxypolysaccharide and magnetic iron oxide, which is characterized by being obtained by oxidizing a complex comprising a water-soluble carboxypolysaccharide and magnetic iron oxide. Said oxidized complex has very low toxicity, is very stable, exhibits little or no blood pressure-reducing action and has low platelets-aggregating action when administered directly into the blood vessels of animals, and is useful in medical fields such as contrast medium for magnetic resonance imaging, exothermic medium for hyperthermia and the like.
摘要:
A two-dimensional image is displayed on a screen (SC) by scanning the screen (SC) two-dimensionally with light beams from a laser light source (1) that are deflected to orthogonally-intersecting first and second scanning directions by means of a mirror (10) in a deflection apparatus (3). The deflection apparatus (3) is arranged to incline obliquely in the second scanning direction (e.g. vertical direction) lower in a scanning speed than the first scanning direction (e.g. horizontal direction), and performs an oblique projection onto the screen (SC). Assuming a direction in which the incidence angle of a light beam deflected by the deflection apparatus (3) and entering the screen (SC) increases in the second scanning direction is positive side, the light beam from the laser light source (1) impinges on the deflection apparatus (3) from the negative side in the second scanning direction, and the normal to the mirror (10) in the deflection apparatus (3) in a state where the center of the screen is displayed inclines to the negative side in the second scanning direction with respect to the normal to the screen (SC).
摘要:
Scanning projection device PJ two-dimensionally deflects a beam emitted from light source unit 1 and performs scanning with deflection element 3, and projects the beam obliquely on screen SC with projection optical system 7. By defining a range of an incident angle to screen SC properly, projection optical system 7 does not disturb an observation of images, and a correction of a spot shape does not become difficult. Further, by defining a ratio of scan-angle magnifications between in the vertical direction and the horizontal direction properly, difference in resolution between in the vertical direction and the horizontal direction can be reduced, and a high-quality and excellent image can be displayed, even when a beam obliquely projected.

A very safe therapeutic composition having a sufficient curative effect on hyperparathyroidism of a patient subjected to artificial dialysis, which composition contains as the active ingredient at least one member selected from .gamma.-linoleic acid, dihomo-.gamma.-linolenic and derivatives thereof.
摘要:
The printer drives the sheet feeding mechanism in response to the initial sheet-setting command and both the first sensor's and the second sensor's detection of no sheet, first forward until the second sheet sensor detects no sheet, then backward until the second sheet sensor detects no sheet, and finally forward the predetermined distance. The paper is neither caught nor crumpled near the exit of the first sheet supplier when the paper is fed backward.
摘要:
An oblique projection optical system enlarges an image formed on a display device surface, and obliquely projects the enlarged image on a screen surface. The oblique projection optical system has, in the order from a reduction side: a refraction optical portion having a positive optical power, a concave reflection surface having a positive optical power, and a convex reflection surface having a negative optical power. The refraction optical portion includes a rotationally symmetric coaxial refraction group. An intermediate image of the image formed on the display device surface is formed between the refraction optical portion and the concave reflection surface. An aperture stop image is formed between the concave reflection surface and the convex reflection surface. The concave reflection surface and the convex reflection surface fulfill prescribed conditional formulae.
摘要:
The number of signal lines needed to communicate a plurality of data types and a plurality of data status levels is reduced and the system cost thereby reduced. A first function unit 1 and a second function unit 2 of the function units in an electronic device are connected by a signal bus 3 for communicating a plurality of data types and a plurality of data status values. The first function unit 1 and second function unit 2 each have a data table of status patterns assigning status values to the data types. The first function unit 1 converts the status pattern to conversion data by referring to the data table and sends the conversion data to the second function unit 2. The second function unit 2 reconverts the received conversion data to the status pattern by referring to the data table.
