Title: Gas-doped getter device
Inventor: OKAI TADAKI
IPC: H01J17/18
Filed: 1982-12-23
Abstract: PURPOSE:To exhibit adsorbability of the captioned device up to the maximum, by adding aluminum powder into the getter material. CONSTITUTION:A container is filled with barium-aluminum alloy powder, nickel powder, nitride and aluminum powder, all of which act as getter material. The addition quantity of aluminum powder is preferably to be 1.6-3.8wt%. In the preparation of the barium-aluminum alloy, if excessive aluminum is charged in the composition, free aluminum may be existent present, but this aluminum is flaky and not mixed uniformly.

IPC: C21D9/00
Filed: 1986-09-24
Abstract: PURPOSE:To enable execution of adequate temp. control of a heating furnace by adequately correcting the quantity of the heat that the ingot to be detected of its temp. receives from the positional relation with the in-furnace ingots, more particularly the adjacent ingots. CONSTITUTION:A temp. distribution arises in the longitudinal direction of the ingots according to how the ingots are positioned adjacent to each other if the ingots of different lengths line up in a heating furnace 1. However, this method permits the execution of the heating control to take said temp. distribution into consideration by adequately recognizing the temp. distribution.
