Abstract: PURPOSE:The reaction between a fluorine gas containing halogen and elementary carbon permits technically safe, easy and economically advantageous production of high-purity carbon tetrafluoride used as a cryogenic refrigerant or an etchant for semiconductors. CONSTITUTION:At least one selected from halogens such as I, Br, or Cl and/or at least one selected from halogen fluorides such as IF6, IF7, BrF3 and ClF3 are added to a fluorine gas. The resultant gas and an equivalent amount of elementary carbon, preferably petroleum coke crushed in an appropriate size are continuously fed to effect the reaction in a temperature range from 250 deg.C to 500 deg.C to produce a colorless gas of carbon tetrafluoride boiling at -128 deg.C and melting at -184 deg.C. The amount of the halogen or halogen fluoride added is more than 0.5mol/100mol of the fluorine gas in case of halogen or more than 1mol in halogen fluoride and a halogen fluoride is preferred.

Title: Substrate mounting structure for electronic part
Inventor: HAGA SHOICHI
IPC: H05K1/18
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To easily lessen weight stress on a substrate without making another member hold a weight parts. SOLUTION: Attaching/fixing of a weight parts 4 to a substrate 1 and attaching/fixing of the substrate 1 to a base material 13 are performed for integration with a common screw 16. By this, the weight parts 4 is directly attached/fixed to the base material 13, so that weight stress of the weight parts 4 is not directly applied on the substrate 1. Thus the substrate 1 is not bent or distorted with the weight parts 4 without holding the weight parts 4 with another member. Thus the weight stress on the substrate 1 is easily lessened only by employing such structure as this for each weight parts 4.
