    摘要： The polyimide film of this invention is formed from a polyimide, which is prepared by reacting a diamino compound represented by the general formula (1): ##STR1## wherein X represents a hydrocarbon group having 1 to 20 carbon atoms or a sulfur atom; R represents each independently a halogen atom, a hydrocarbon group having 1 to 6 carbon atoms or a halogen-containing hydrocarbon group having 1 to 6 carbon atoms; a represents each independently an integer of 0 to 4; with a tetracarboxylic dianhydride represented by the general formula (2) ##STR2## wherein Y represents a tetravalent organic group having 2 or more carbon atoms. The polyimide film obtained can be applied favorably to a flexible printed circuit board without adhesion layer, a protective coating for electronic parts and electric wires, or a heat resistant adhesive.

    摘要： The polyamino oligomers of this invention are obtained by reacting diisopropenylbenzenes or bis(.alpha.-hydroxyisopropyl)benzenes and anilines in the presence of an acid catalyst and characterized by the recurring unit having an indane skeleton. These polyamino oligomers can be used as curing agent for laminate resins. Also, they can be reacted with maleic anhydride to prepare polymaleimide compounds of this invention.The polymaleimide compounds of this invention are low in melting point (or softening point) and, in combination with a substance producing three-dimensional crosslinkage such as triallyl isocyanurate, aromatic diamine, etc., can provide thermosetting resin compositions suited for producing copper-clad laminates. The copper-clad laminates obtained from the thermosetting resin compositions of this invention are low in dielectric constant, heat-resistant and also low in water absorptivity, so that they are useful for multi-layer printed boards.

    摘要： A heat roller for a fixing device included in an image forming apparatus has an insulation layer and a conductive layer sequentially formed on the inner periphery thereof. To form each of the insulation layer and conductive layer, a spray gun is inserted into the heat roller. Subsequently, paint, which is a liquid for forming the insulation layer or the conductive layer, is fed under pressure to the spray gun. The paint is radially jetted via the holes of the spray gun and evenly deposits on the inner surface of the heat roller. In this condition, the spray gun is moved in a preselected direction in order to coat the entire inner periphery of the heat roller. After the insulation layer has been formed and then sintered, the conductive layer is formed on the insulation layer and then sintered. The two layers can be formed in a short period of time and provides the heat roller with high quality at low cost. A method of producing the heat roller is also disclosed.

    摘要： An access control apparatus, method, and recording medium for storing a program, provides equal input/output (IO) opportunities to auxiliary memory units for all users by attaching priority information for each user to user-entered IO commands. The prioritized IO commands are stored in an IO queue corresponding to a particular one of the auxiliary memory units, and physical IO is performed on each of the auxiliary memory units in the sequence of priority information attached to the prioritized IO commands in each IO queue irrespective of who the entrant users are.
