Title: Data processing system
Inventor: NISHIHARA MASATO
IPC: G06F7/76
Filed: 1987-06-17
Abstract: PURPOSE:To decide the overflow at high speed for the processing result of the variable length data and at the same time to reduce the capacity of a processing program, by securing an AND between the processing result of the fraction data and deciding whether the processing result of the fraction data has an overflow or not. CONSTITUTION:When the processing is through excluding the fraction data, the length of the variable length data is held. Then such a constant is produced by the value (b) shown by lower (a) bits of said variable length data that the bits of the b-unit are all equal to logic 0 together with other bits equal to logic 1 respectively and with the higher or lower bit number (a) of the variable length data defined as a single unit. An AND is secured between the processing result of the fraction data and said constant and it is decided whether said processing result has an overflow or not. As a result, the fraction data on the variable length data can be simply processed. Thus it is possible to decide at a high speed whether the processing result of the variable length data has an overflow or not and also to reduce the capacity of a processing program.

IPC: F23D11/40
Filed: 1977-12-15
Abstract: PURPOSE: For increasing flame keeping capacity, to eliminate the extreme difference between the combustion speeds upon ignition and steady combustion by making a number of burner slits slantly of the depth direction of the circumferential side wall of a cylindrically-formed burner head.  
     CONSTITUTION: Burner slits 14 are slantly made in the circumferential side wall of a burner head 13 vertically and slantly so as to have a fixed angle with the depth direction of said cirumferential wall.
