摘要:
A recording and/or reproducing apparatus for discs including a housing unit housing a large number of discs, a recording and/or reproducing unit on which one of the discs held within a large number of disc holders provided in the housing unit is selectively loaded and a transporting mechanism for transporting the disc held within a pre-set one of the holders of the housing unit to the recording and/or reproducing unit. In the course of transporting the disc, the disc transporting mechanism detects whether or not the disc is held in the holder. The housing unit include a plurality of the holders for radially holding the discs with the disc surfaces being erected upright. The disc held in the holder is transported by the transporting mechanism in the upstanding position as far as the disc reproducing unit and there loaded. The recording and/or reproducing apparatus for disc-shaped recording media has a group designating unit for designating the information of a desired one of the recording media housed within the housing unit and the air information recorded on such desired disc-shaped recording medium and grouping the designated information for classing the large number of the recording media into several groups.
摘要:
A black steel sheet having a sufficiently small coating thickness to allow the welding of the steel sheet, and yet exhibiting an excellently black surface. It is a steel sheet having a surface plated with zinc or a zinc alloy, and carrying a chromate film formed on its plated surface, and a black film formed on the chromate film from a composition comprising specific proportions of a thermosetting resin and a black dye, which are both soluble in an organic solvent, and having a sufficiently small thickness. The composition may further contain a solid lubricant, or a granular rust-inhibitive pigment, or both.

A multi-color filter without a so-called bipolar phenomenon for use of color liquid crystal display devices is prepared by such a manner that plural sets of electroconductive circuits are prepared on transparent substrate; a given set of circuits on which a first color layer is to be formed is provided with a feeder circuit traversely in one lot; and the first electrodeposition is conducted by applying a current only to this set of circuits in order to impress a given voltage while voltage is increased gradually to a given level over a certain period of time, thereby forming the first color layer, and the electrodeposition is repeated in the similar way by applying current to each of the remaining sets of circuits.

A high-ortho phenolic novolac resin having excellent curability, heat stability and flowability can be produced safely at low cost by a process which comprises reacting a phenol and an aldehyde at a temperature of more than 100.degree. C. with (A) a catalyst effective for the addition reaction selected from the salts of divalent metals in combination with (B) a catalyst effective for the condensation reaction, or comprises reacting a phenol and an aldehyde under reflux in the presence of the catalyst (A), adding an acid to adjust the pH to 1-5, removing water under reduced pressure and then subjecting the product to reaction at a temperature of more than 100.degree. C. This process enables the addition reaction and the condensation reaction to proceed with a good balance, can solve problems arising in the prior process such as gelation, low yield and the like, and can produce a high-ortho type phenolic novolac resin safely at low cost. Accordingly, this process is quite advantageous in industry.

Novel antimicrobial substance C-3603 was obtained from the culture of Streptococcus mutans C-3603, FERM-P No. 4128, ATCC No. 31383. The novel antimicrobial substance C-3603 shows a high antimicrobial activity against a variety of gram-positive bacteria, particularly cariogenic bacteria in the oral cavity and it is expected for the utilization to prevent oral infectious diseases, particularly dental caries.
摘要:
A transfer apparatus is provided of the type in which a toner image formed on a photosensitive member is transferred onto a transfer or copy sheet. The apparatus is used in a copying machine of a so-called delivery type in which the sheet is conveyed using a sheet gripper. During the transfer of a toner image, the appartus applies a corona discharge to the rear side of the sheet which is of the opposite polarity from that of the toner image. The apparatus comprises a diaphragm member for restricting an opening of a transfer charger and disposed between the transfer charger and the photosensitive member, the diaphragm member being movable away from the photosensitive member as the sheet gripper passes between the transfer charger and the photosensitive member.
摘要:
A distal end of an inserted pole makes contact with a bottom surface or tapering surface of a portion corresponding to a bottom of an insertion hole. A lever rotates about a pivot shaft, and a pressing surface facing from a recessed portion formed in the insertion hole presses a side surface portion of the pole. The pole pressed by the pressing surface is mainly received by ridge portions, particularly the ridge portions positioned on the opposite side with a central axis therebetween in relation to the pressing surface. The ridge portions are positioned on both sides of the pole with the cross section along the line A-A therebetween as viewed in the axial direction. As the lever is rotatably operated in the tightening direction, the pressing position gradually approaches the central axis, thereby increasing the pressing force.
摘要:
An image processing device for converting an input image into an output image whose blur is reduced. The image processing device includes a first image extracting section that extracts a plurality of pixels composed of a pixel of the input image corresponding to a pixel of interest in the output image and predetermined pixels surrounding the pixel of the input image. A first feature quantity calculating section calculates a first feature quantity from the plurality of pixels extracted by the first image extracting section. A second pixel extracting section extracts a plurality of pixels composed of the pixel of interest and predetermined pixels surrounding the pixel of interest from the input image. A predicting section then generates a pixel value of the pixel of interest.
