Abstract: A showcase includes: a case main body; and article mounting shelves that mount articles as objects to be stored. The showcase causes the articles to be visually recognized through a customer serving face. Each of the article mounting shelves includes: a pair of brackets supported by a pair of shelf columns; and a shelf board. Each of the brackets includes locking pieces that are provided with respective notches at lower ends of predetermined areas. The showcase is supported by each of the shelf columns by causing the locking pieces to be inserted into corresponding inner face locking holes formed on an inner face of each of the shelf columns and causing lower edges of the inner face locking holes to relatively enter the notches, to cause the locking pieces to be locked to the inner face locking holes.

Abstract: Fire retardant tablet is provided which is produced by tableting a fire retardant mixture containing heat-expandable graphite (A), and a water-soluble fire retardant synergist (B) or one containing additionally water-insoluble fire-retardant synergist (C). A method for fire retardation, a fire-retardant polymer composition, and a molded article of a fire-retardant resin by use of the fire retardant tablet are also provided. In the production of a fire retarding polymer composition containing heat-expandable graphite, the crushing of the heat-expandable graphite under melt-shearing is minimized.

Abstract: A selector sequentially selects different coefficients during a time interval T. A plurality of coefficient multipliers multiply an input signal sampled at intervals T and coefficients selected by the selector. An input circuit selects, at interval T/2, an input signal supplied at intervals T. A pipeline type adder adds an output signal of the input circuit and output signals of the coefficient multipliers. An output circuit adds an output signal of the adder in an interval of T/2 and outputs the result of the addition as a signal of a period of T.
