Title: Manufacture of steel having superior resistance to sulfide cracking
Inventor: TSUMURA TERUTAKA
IPC: C22C38/00
Filed: 1983-08-31
Abstract: PURPOSE:To manufacture a steel having superior resistance to sulfide cracking by restricting the chemical composition of a steel and conditions during rolling and heat treatment. CONSTITUTION:The composition of a steel is composed of, by weight, 0.15- 0.45% C, 0.01-0.1% Nb, Ti and/or Zr satisfying Ti+1/2Zr=0.005-0.05%, and the balance essentially Fe.

Patent JP-H0210032-A (JP)
Title: Hot air space heater
Inventor: OGINO TOSHIRO
IPC: F24D5/02
Filed: 1988-06-28
Abstract: PURPOSE:To uniformly heat the total space of a room by a method wherein a hollow duct which has a hot air passage therein and multiple hot air outlet ports perforated on the upper surface thereof is arranged on the floor surface in the vicinity of a wall surface in the room or at the lower part of the wall surface so as to cover at least the total length of the wall surface and hot air is introduced through a part of the duct. CONSTITUTION:Hot air generated by a hot air generator 1 is introduced into a duct 3 and blown upward out of multiple hot air outlet ports 4 perforated on the upper surface of the duct 3. Since the duct 3 is arranged in the vicinity of a wall surface, a portion of warm air ascends while heating the wall surface cooled by the external air, and the vicinity of the duct 3 causes negative pressure due to the outlet of hot air and the ascending stream of warm air. As a result, air near a floor surface, which is relatively low at a temperature, moves toward the duct 3 and is heated by hot air blown out of the hot air outlet ports 4. Accordingly, in a room is generated a large circulating stream of air which ascends above the duct 3 and decends in a space ranging from the substantially central part in the room to the vicinity of a wall surface opposed to the wall surface where the duct 3 is arranged. Thus, the inside of the room can be heated almost uniformly.
