Title: Flame characteristic adjustable low nox burner
Inventor: MATSUZAKI KATSUNARI
IPC: F23D14/22
Filed: 1978-07-11
Abstract: PURPOSE: To provide the subject burner of a compact structure similar to that of the conventional type burner, wherein generation of nitrogen oxide is remarkably reduced to burn the fuel.  
     CONSTITUTION: The interior of tiles is brought into a negative pressure by the ejector effect due to the injection of air and fuel, and burned gaseous wastes 3 of high temperatures in the spaces within the burner are attracted along the tile wall up to the baffle surface 2. Thereafter, the gaseous wastes 3 flow on the baffle surface 2, and wrap air injection streams 5 and 6 in the tiles. In the primary combustion, the surface combustion 4 is carried out up to the impact surface 9 of injection streams 5 and 6 by residual oxygen in the gaseous waste 3 thereby to accelerate the mixing of the primary combustion gaseous wastes with fuel. On the pther hand, the mixing of the gaseous wastes 3 with combustion air is accelerated up to said impact surface 9, and converted into air of a low O 2  partial pressure and rapid combustion thereof is suppressed. At a part denoted by a the secondary combustion is started. however, since high temperature gaseous wastes within the burner are involved in said part, combustion becomes slow without lowering the flame temperature, and generation of NO x  is extremely inhibited.

Title: Circuit for detecting runaway of computer
Inventor: TAGUCHI YOUICHI
IPC: G06F11/00
Filed: 1983-05-13
Abstract: PURPOSE:To use the titled detecting circuit together with other runaway detecting means and to improve the detecting probability by providing the titled circuit with an address setter, an address comparator, a coincidence detector, etc. and comparing a setting address with a current address to detect the coincidence of the whole digits. CONSTITUTION:The address setter 6 sets up a binary number consisting of three digits and sends binary signals corresponding to respective digits to an address comparator 4 through an address output terminal 7. The comparator 4 compares the binary signals with binary signals from an address bus 2 in each digit and sends the coincidence or inconsistency to a coincidence detector 9. When the signals of the whole digits coincide with the sigals from the bus 2, the detector 9 sends a coincidence signal. The coincidence signal indicates that any address in an unused area of a memory which is set up by the setter 6 is designated by the address bus at present and shows the generation runaway. Thus, the detecting probability by runaway can be improved by detecting the runaway by the runaway detecting circuit and using the circuit together with other runaway detecting means.
