Abstract: A steel laminate gasket comprises a plurality of thin steel plates to be stacked one after another, and devices for identifying the position of the steel plates formed on the steel plates where no sealing ability is affected. When the steel plates are stacked in the proper order, the devices form a stepped portion with different height relative to a predetermined horizontal plane of the gasket. Consequently, a user can notice the proper order of assembly of the gasket.

Abstract: A multi-item data input apparatus is disclosed whereby an operator can designate one of a plurality of items by actuation of a key, thereby generating a signal indicative of that item. The items are visibly printed or written on a number of item information sheets, each of which is enclosed between a transparent cover sheet and a base sheet each of which is flexible, with the sheets being rolled around a cylindrical holder in a successively overlapping manner. Means are provided whereby a sheet set, comprising an item information sheet with cover sheet and base sheet, can be selectively unrolled and positioned below a keyboard having transparent keys, to allow designation of items on that item information sheet. The item information sheets can be rapidly and conveniently removed, for exchange of sheets or for modification of item information.
