In a stacker for successively stacking cut papers on a bottom plate, a winding shaft for winding a non-cut continuous paper therearound is provided on a back side plate so as to project substantially perpendicularly to the paper restriction surface of the back side plate. This structure of the stacker makes it possible to stack the cut papers successively on the bottom plate and also makes it possible to easily wind the continuous paper around the winding shaft. In the stacker for successively stacking cut papers therein by inserting a cut paper beneath the previous stacked papers comprising a paper press for pressing the stacked papers from the top surface thereof and a press force switching mechanism for contacting the paper press and applying press force to the stacked cut papers until the stack height of the stacked papers reaches a prescribed value and for releasing the application of the press force when the stack height of the stacked papers exceeds the prescribed value. This structure makes it possible to apply always an appropriate press force to the stacked papers and to stack the papers on the bottom plate with assurance.
摘要:
A rewriteable card of the invention is composed of a thermally reversible thermosensitive recording material which changes reversibly between a slightly opaque state and a transparent state depending on a given heating condition wherein the rewriteable card includes a reference slightly opaque portion at the part thereof having the reflectance equivalent to a slight opacity state of the thermally reversible thermosensitive recording material in an early stage or a last stage of use of the rewriteable card. A method of judging the life of the rewriteable card is based on the result of detection of the reflectance on a printing slightly opaque portion and that on the reference slightly opaque portion, and a printing apparatus is provided with a card life judging device employing the judging method.

The compound exhibits a superior antimicrobial activity, especially against gram positive microorganisms, and is thus useful for the treatments and prevention of various infectious diseases in clinics.
摘要:
In detecting indices (references) provided on a base paper with a distance therebetween along the longitudinal direction of the base paper, wherein either passed or reflected light amount through or from the indices differs, by a light detector positioned on a feed path while the indices are fed along the longitudinal direction, a threshold value is renewed each time when at least three indices are detected based upon peak values (maximum and minimum values) of output signals from the light detector. This is accomplished by renewing the threshold value by calculating the new threshold value based upon an intermediate or average value among the peak values between, for example, the indices in order to continue the indices position detecting process in an accurate fashion even if there is an abnormality in the base paper or others when the abnormality is minor such that it does not interfere with the subsequent process.
摘要:
Novel imidazole derivatives and their acid adducts are disclosed. The imidazole derivatives are represented by formula: ##STR1## wherein R.sub.1 represents an alkyl group, R.sub.2 represents a hydrogen atom, an alkyl group which may have a substituent, or an aralkyl group which may have a substituent, provided that R.sub.1 and R.sub.2 are not both methyl groups at the same time. They have strong antimicrobial activity, especially against those fungi belonging to the genera Candida, Trichophyton, Microsporum, and Epidermorphyton, as well as against Gram-positive bacteria, and thus is useful as an antimicrobial agent.
