Title: Original reader
Inventor: YAMAGUCHI TETSUJI
IPC: H04N1/10
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of the reader by decreasing the number of sensors that sense a size and a direction of an original. SOLUTION: An original size.direction sensor 7 senses an original of a size that cannot be sensed by original size sensors 3-5. For example, when the original size sensors 3-5 can sense an original of longitudinal A4 size/lateral A5 size or over, the original size.direction sensor 7 can sense an original of longitudinal B5 size that cannot be sensed by the original size sensors 3-5. Furthermore, whether an original is placed longitudinally or laterally is sensed based on the presence of sensing of the original by the original size.direction sensor 7. Thus, the original size.direction sensor 7 can discriminate the original of longitudinal A3 size/lateral A4 size, longitudinal B4 size/lateral B5 size, or longitudinal A4 size/lateral A5 size.  Then total number of the sensors is decreased to reduce the cost by using the original size.direction sensor 7 to detect the original size and the placing direction of the original in this way.

Title: Exterior wall panel
Inventor: SUZUKI TOSHIRO
IPC: E04C2/06
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To obtain an exterior wall panel in which a foamed concrete board can be firmly fixed to a frame body and which prevents the foamed concrete board from breaking. SOLUTION: A foamed concrete board 2 in which a metallic mesh 1 is buried in almost the whole face thereof is fixed to a frame body 3 by fixing tools 6. Since the metallic mesh 1 is buried in almost the whole face of the foamed concrete board 2 in this way, when the foamed concrete board 2 is fixed to the frame body 3 with the fixing tools 6, the fixing tools 6 are completely caught by the metallic mesh 1. Hence, the foamed concrete board 2 can be firmly fixed to the frame body 3 and the board 2 is prevented from breaking even at the breakable edge thereof. Even when an original foamed concrete board 2 is cut for use, the metallic mesh 1 is left and hence, the strength is not decreased.
