Title: Fire-resistant cover structure
Inventor: IKEDA KENICHI
IPC: E04B1/94
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To provide a fire-resistant cover structure having no possibility of being dropped at a low cost without increasing the practical beam depth of a steel frame beam by filling a fire-resistant cover material into spaces surrounded by the upper flange and lower flange of the steel frame beam and a web between the upper and lower flanges. SOLUTION: A fire-resistant cover material 12 such as rock wool is filled into spaces A, A surrounded by the upper flange 10a, lower flange 10b, and web 10c of a steel frame beam 10 into a nearly U-shape, and it is sprayed to cover the side edge sections and the lower face of the upper flange 10a and the lower flange 10b. The fire-resistant cover material 12 has the heat conductivity lower than that of the steel frame beam 10, it suppresses an abrupt temperature rise caused by a fire, and it can exert a temperature rise suppressing effect because of its large volume. Since it is not required to be sprayed thick, it has no possibility of being dropped, and the practical beam depth is prevented from being increased because its spraying thickness to the lower face of the lower flange 10b of the steel frame beam 10 can be suppressed.  Its specific gravity is small, it is inexpensive, the weight is largely suppressed, and the cost can be reduced.

Title: Numerical controller
Inventor: YONEDA TAKAO
IPC: G05B19/18
Filed: 1992-09-26
Abstract: PURPOSE:To completely perform the debugging work of an NC program with single block execution by effectively utilizing a structured description format so as to process the condition judge part of a conditioned control sentence and the processing part of a branch destination as different blocks. CONSTITUTION:The control condition discrimination part of the conditioned control sentence and the processing part of the branch destination are defined as different blocks. For example, the block of an IF sentence is partitioned like a figure and when one block is executed from a pointer (1) and a 'condition expression' is true, single block stop is performed by a pointer (2) or when it is false, single block stop is performed by a pointer (3). In this case, both of an NC sentence and a macro sentence are available for sentences 1 and 2. Since the condition discrimination and the machine operation are not executed in one block, the program debugging of a structured NC language is enabled on the same operation environment as the conventional single block execution.
