Title: Character processing device
Inventor: KASHIMA YOZO
IPC: B41J5/44
Filed: 1992-12-16
Abstract: PURPOSE:To improve processing speed in a character processing device which utilizes a font cache memory. CONSTITUTION:In a font cache memory 300, diagram data such as characters are registered as dot pattern. A registration/un-registration determining means 100 determines whether an output request character is being registered in the font cache memory 300 or not. When it is being registered, a first read means 200A is started. When it is unregistered, a second read means 200B is started. The first read means 200A reads out, from the font cache memory 300, an 'identical character' which coincides with the output request character in kind of character, size of character, and typestyle. The second read means 200B reads out a 'similar character' with which only kind of character and size of character coincide.

Title: Foundation for cylindrical tank
Inventor: SHIBUE TADASHI
IPC: B65D90/12
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To prevent a cylindrical tank from laterally sliding at the time of an earthquake to improve safety. SOLUTION: The foundation 1 for a straight-standing cylindrical tank includes an upper face of the foundation having a smooth concentric protruding form wherein a position corresponding to a center of a tank bottom 4 is the highest or a smooth concentric recessed form wherein the position corresponding to the center of the tank bottom is the lowest. When a typical cylindrical tank having a flat bottom is placed on the upper face of this foundation, the tank bottom comes into tight contact with the upper face of the foundation by its own weight. When liquid is filled inside, the tight contact further increases. Since the upper face of the foundation has a protruding or recessed form, frictional resistance increases so that the tank may be difficult to slide with respect to horizontal force of an earthquake.
