Abstract: A deinking agent comprises a compound of the following formula (I);N(R.sup.1)(R.sup.1) R.sup.2 (I)wherein R.sup.1 is --C(O)R.sup.4 or --(C.sub.2 H.sub.4 O)C(O)R.sup.4 ; R.sup.2 is --(C.sub.2 H.sub.4 O)--(AO).sub.m or --(AO).sub.m ; R.sup.3 is --C(O)R.sup.4 or --(C.sub.2 H.sub.4 O)C(O)R.sup.4 ; R.sup.4 is C.sub.9-23 alkyl or C.sub.9-23 alkenyl; m is a integer from 40 to 100 and A is C.sub.2-4 alkylene, and a quaternary ammonium compound thereof in a molar ratio of 9/1 to 1/9. The deinking agent for reclaiming printed waste paper has abilities to efficiently release the ink from the waste paper in the disintegration process and to collect the ink and produce suitable foam in the flotation process, which provides high quality reclaimed pulp having high whiteness and a low content of remaining ink.

Abstract: A lubricating oil composition comprises an alkylnaphthalene which has one or two alkyl groups each having from 8 to 30 carbon atoms, and at least one member selected from benzo(b)thiophene and derivatives thereof, and naphthalenethiol and derivatives thereof. The composition has good oxidative stability.

Abstract: Herein discolosed is a software information reusing system comprising: a data base for storing software information; a dialogue display terminal; thereby processing the information inputted from the display terminal. First retrieval information of the software information is registered as data related with a link of a data information related concept. If second retrieval information is not in the registered data, it is judged on the basis of the link of the related concept whether or not third retrieval information related therewith exists. The data base is retrieved on the basis of the third retrieval information.

Abstract: A display board illuminating device includes a light guide plate arranged to face the back of a display board and a light source disposed to face the side end of the light guide plate. The side end of the light guide plate is inclined toward the center of the light guide plate in the direction of the display board. By this configuration an angle of an optical axis refracted at the surface of the side end and incident into the light guide plate with respect to a main surface of the light guide plate, so that the whole area of the display board is illuminated efficiently.

Abstract: Automatic layout planning without previously specifying place of each parts is made possible by utilizing groups of rules each comprising a condition section and a procedure section. An appropriate group of rules can be called from a knowledge base according to an intermediate layout plan generated in a data structure by a rule interpreter.

Abstract: A photographic support comprising a polyolefin coating on both surfaces of a paper sheet, in which the surface reflection characteristics are in a range of L being above 90, a being from 0.5 to 1.5 and b being from -3 to -5 on the surface on which an image forming layer is to be coated, with the surface reflection characteristics being measured in accordance with JIS Z8722 and defined in accordance with JIS Z8730.
