Abstract: A wet type sliding apparatus in which a multilayer sliding member is used in the presence of a lubricating oil, characterized in that the multilayer sliding member is composed of (1) a backing metal layer, (2) a porous, sintered layer provided thereon and (3) a surface layer consisting essentially of polyetheretherketone formed by impregnating and coating the porous, sintered layer with a sliding resin consisting essentially of polyetheretherketone. The above sliding member has a small friction coefficient and excellent wear resistance. In particular, the sliding noise can be more effectively inhibited by adjusting the face roughness of the surface layer of the sliding member to 2 .mu.m or less.

Abstract: A system for performing the desired transaction when the customer follows a specified procedure comprising a sequence of steps includes an electronic visual display unit for displaying a message and a graphic illustration at the same time, and a plurality of functionally operative physically manipulative function units arranged around the display unit. The physical operations are performed by the customer in a sequence of steps, and some of the function units serve different functions for different steps. The display unit displays stepwise, immediately before each of the steps is performed by the customer, an instruction comprising the combination of a procedure specifying textual message describing the procedure to be followed by the customer and a procedure specifying graphic illustration pictorially depicting the physical enactment of the procedure in corresponding relation to the message.
