Title: Electron flood device for neutralizing charge accumulation on substrate in ion implantation
Inventor: ITO HIROYUKI
IPC: H01L21/265
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To neutralize the positive charge accumulation on a substrate during ion implantation into the substrate by introducing a low-energy electron flux from a chamber to a tube through an outlet port, and combining it with an ion beam. SOLUTION: When a plasma is formed with in a plasma chamber 15, the plasma species tends to move through an outlet port 16 and form a plasma bridge with an ion beam 12. Since the mobility of electron is high, compared with that of argon ion, the electron flux from the plasma chamber 15 is naturally larger in size than the ion flux by about two orders of. Since the plasma within the plasma chamber 15 tends to be positively charged by this, the electron flow passing the outlet port 16 is reduced and then finally stopped. The plasma can be discharged by the presence of an electrode 21, so that the current flow passing the outlet port 16 can be kept in a controlled flow rate.

Title: Fatigue strength measuring method for engine valve
Inventor: SATO KOJI
IPC: G01M13/00
Filed: 1994-07-28
Abstract: PURPOSE:To simply, quantitatively evaluate fatigue strength by locally heating a boundary between the neck and the shaft of an engine valve to a highest temperature, and repeatedly applying a tensile stress until it is broken in the vicinity of the boundary. CONSTITUTION:For local heating means, a high-frequency induction heat having narrow heating range and easy temperature control is desirable. Since a heating position may be the vicinity of the boundary between the neck and the shaft of an engine valve for generating a fatigue destruction, a large-scale heater is eliminated. For a fatigue tester for applying a tensile stress, a tensile-tensile type in which a repetitive stress is applied to a test piece similarly to the stress loading state of an actual machine, is preferable. The piece is clamped by hydraulic clamping with a jig manufactured to match the actual valve shape. However, it is necessary to carefully consider the shape of the jig and the size of the high-frequency coil so that the jig is not excessively large to cause a high temperature. A thermocouple is mounted at a site of the highest temperature to measure the temperature, thereby, it is made possible to generate the fatigue crack and destruction at a highest temperature.
