Abstract: A printing apparatus for use in a printer with a photo-sensitive drum. The printing apparatus includes a spotlight source for generating a light provides essentially a point source. A fiber-optical converter which is optically coupled to the spotlight source converts the light from the spotlight source to linear rays of light. A plurality of shutter window optically coupled to the fiber-optical converter selectively transmits the light at selected portions of the array to the photo-sensitive drum. As a result, a light path is defined from the spotlight source through the fiber-optical converter and the microshutters to the photo-sensitive drum.

Abstract: Disclosed herein are N-(2-chloro-4-trifluoromethylphenyl)-3-trifluoromethylbenzensulfonamide derivatives represented by the following general formula (I): ##STR1## wherein X and Y individually mean a hydrogen or chlorine atom, and agricultural fungicides containing said derivatives.

Abstract: A method of processing soybeans is disclosed which comprises heating raw soybeans in the absence of added water with superheated steam under atmospheric pressure, and cooling the resulting beans by exposure to the atmosphere. This method permits removing any offensive smell fully from the beans without impairing the natural flavor or taste of the beans.

Abstract: A method and apparatus for making a two-dimensional copy from either a two-dimensional or three-dimensional object is provided. In making a two-dimensional copy from a three-dimensional object, the object is submerged in the liquid contained in a container having a transparent bottom portion to which the object is brought into contact by placing a cover member thereon. The object is then exposed through the transparent bottom portion thereby the projected image of the object viewed through the transparent bottom portion is reproduced on a sheet of copy paper.

Abstract: Disclosed are novel 3-nitrobenzene sulfonanilide derivatives and, among others, that of the formula ##STR1## as well as fungicidal compositions containing such compounds as the active ingredient. The compounds of the invention are markedly effective in controlling plant diseases and, in particular, clubroot disease of Brassica spp., have no toxicity to men, beasts, and fishes, exert no phytotoxicity on crops, have neither irritant nor unpleasant odor, and manifest their excellent fungicidal effect at low concentrations. Accordingly, they are ideally useful in fungicidal compositions.

Abstract: An image transfer unit provided with cleaning means for use in an electrophotographic copying machine comprising an electrically conductive transfer roller disposed in abutting relationship with a photosensitive member, an electrically conductive, rotatable cleaning means disposed in abutting relationship with the transfer roller, and electrical bias means connected with the cleaning means and having a switchable polarity. During a transfer step, a bias voltage of opposite polarity to that of the toner is applied to the transfer roller through the cleaning means. At this time, toner attaching to the transfer roller is electrostatically transferred onto the cleaning means. During a cleaning step, a bias voltage of the same polarity as the toner is applied to the cleaning means, whereby the toner attaching thereto is transferred back to the photosensitive member through the transfer roller. The toner which is transferred back to the photosensitive member is removed by separate cleaning means.

Abstract: The apparatus comprises a projection optical system and a copying system. The projection optical system can project an image of an original either onto a screen or to an exposing position of the copying system by switching between two positions. The copying system comprises a plurality of chargers providing different charging conditions in accordance with the types and sizes of copy sheets, by utilizing a change-over switch. A plurality of switches adapted for use with copy sheets of different lengths are arranged along the path of movement of a sheet of paper and, when the switch corresponding to the particular length of copy sheet desired is actuated, the movement of the sheet of paper is stopped, so that the central portion of the copy sheet can be brought into alignment with the optical axis for exposing at all times regardless of the difference in the length of copy sheets.
