The diameter Do of a column body part 10 is made the substantially same as the outside diameter size of the lower side steel frame column 3 of a large diameter, and formed of equivalent thickness. A projection part 11 seriously forms an inside projection part 11a largely projecting only size necessary for joining of the upper side steel frame 2 toward the inside and an outside projection part 11b necessary for joining of a steel frame beam.  The inside projection part 11a forms thickness (t) and size A so that a support angle in which the flow line of vertical load which leads to a column body part 10 from the upper side steel frame column 2 is formed is 45 degrees or larger. Thereby welding can be surely efficiently performed and quality management of welding can be enhanced high.

Title: Vaporization type combustion device
Inventor: KAWAMURA MITSURU
IPC: F23N5/20
Filed: 1992-07-09
Abstract: PURPOSE:To suitably control the preheating of a vaporizer by controlling the preheating temperature of the vaporizer in a corresponding time zone according to a value stored in a storage area of a memory. CONSTITUTION:When an operation switch 17 is turned ON to start combustion, a predetermined value is added to a storage area in a time zone, to which a memory ME corresponds, according to the counting time of a 24-hour timer TM and, at the same time, a value smaller than the predetermined value is added to the storage areas in the preceding and succeeding time zones of the corresponding time zone. Accordingly, a value in a storage area in a time zone where combustion is frequently started becomes greater. Besides, values which are great to some degree are also stored in the storage areas in the preceding and succeeding time zones of the time zone. Consequently, in the time zone where combustion is frequently started, a preheating temperature of a vaporizer is sufficiently elevated and, even in the preceding and succeeding time zones of the time zone, the preheating temperature of the vaporizer is elevated to some degree.

When ions 2 produced by discharging gases of Ar and the like are applied to the whole surface of the above substrate, a damaged part 4 is shallowly formed at the surface of an exposed part of the silicon single crystal substrate 3. After doing damage 4 to the surface of the substrate in this way, this device allows an amorphous metal 5 to adhere to the whole surface of its substrate. Meanwhile, the amorphous metal 5 is formed by performing the glow discharge in a metal halogenide gas at a low temperature. Then silicide is selectively formed at the exposed part by treating rapidly with heat which is produced through lamps in an inactive gas.
