Abstract: We provide a novel and useful process for preparing triphenyl-butene derivative. A process for the preparation of a compound represented by Formula (IV): wherein R1 is hydrogen or substituted or unsubstituted alkyl, characterized by reacting a compound represented by Formula (V): with a compound represented by Formula (VI): wherein R1 has the same meaning as defined above, in the presence of 1) a polyvalent metal chloride, 2) a reducing agent and 3) an alkali metal salt and/or a substituted or unsubstituted phenol.

Abstract: An input check device generates a connected apparatus table showing the correspondence between recording/reproducing devices and their respective output signals on the basis of instruction signals entered from a connection information setting unit. A storage stores information as to which is the current target of reproduction among the recording/reproducing devices connected to the monitor device and also stores the connected apparatus table generated by the input check device.

Abstract: A fiber reinforced composite belt in which a stainless steel fiber aggregate having a diameter of from 5 to 50 .mu.m and impregnated with 1 to 10% by weight of a thermosetting resin such as an epoxy resin is buried as a reinforcing material in a base material for belt, and a process for preparing the above-mentioned fiber reinforced composite belt are provided. This fiber reinforced composite belt is much more excellent in flex resistance, durability, water resistance and coefficient of linear expansion, as compared with not only a rubber belt and a synthetic resin elastomer belt but also belts reinforced by directly burying a stainless steel fiber and a steel fiber in the rubber.

Abstract: In an electrostatic recording material being composed of a multi-layered sheet support having an electroconductive layer and a dielectric layer formed successively thereon, the number of projections having a height of 10 .mu.m or more from the flat surface is limited to a maximum of 50 per 0.1 m.sup.2, so that the material has excellent properties and can produce prints of very high quality.
