Filed: 1987-01-31
Abstract: PURPOSE:To produce a cast iron member having superior corrosion and fatigue resistances by chilling a prescribed part of the surface of a graphite cast iron member, decarburizing the chilled part and plating it with a corrosion resistant metal. CONSTITUTION:When a member is cast in graphite cast iron such as flake graphite cast iron or spheroidal graphite cast iron, the surface of a specified part of the member is chilled by rapid cooling, or the surface of a specified part of a cast graphite cast iron member is chilled by partial melting with high density energy such as laser beams or TIG arc and by resolidification by rapid cooling. The member is heated in a decarburizing atmosphere to decompose eutectic cementite in the chilled structure and cementite (Fe3C) in pearlite in the structure and to remove C as CO or CO2. By this decarburization, the chilled surface is made free from graphite and holes due to the escape of graphite. The surface is then plated with a metal or alloy having superior corrosion resistance such as Ni, Ni-P or Ni-Cr to produce a graphite cast iron member having improved corrosion and fatigue resistances at a specified part.

Title: Field effect transistor and its manufacture
Inventor: EMERU ESU BUURATSUTO
IPC: H01L29/772
Filed: 1993-01-18
Abstract: PURPOSE: To improve the linearity of the capacity of a device by adopting ion-implantation process in two stages. CONSTITUTION: N-type impurities of the lightly administered quantity of phosphorus or arsenic are implanted with high energy, and a first band 29 is generated in a source face region 21. Then, a second band 30 is generated in the respective first bands 29 by ion-implanting the N-type doping material of heavily administered quantity with a low energy level. Source and gate members 33A and 33B are brought into ohmic-contact with the second band of the source region 29 and a gate region 25 in the source and gate face regions. When the N-type doping material of lightly administered quantity is guided in the first band deeper than the source region of a conventional system, the impurity density of silicon in an epitaxial growth layer increases only in the narrow part of the channel region of a device, where the pinch-off of the device occurs.  The change of impurity density reduces a gate-drain junction capacitance at a low drain voltage and improves the linearity of device capacitance.
