Title: Corrosion resistant member
Inventor: TSUKATANI TOSHIHIKO
IPC: H01L21/3065
Filed: 2005-10-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide a corrosion resistant member whose surface exposed to a chlorine-based corrosive gas can be sufficiently resistive even to the chlorine-based gas or exposure of its plasma, which can avoid the deterioration of an anticorrosion performance caused by periodical cleaning, and which can avoid surface contamination.  <P>SOLUTION: The corrosion resistant member is made of a material to be exposed to a chlorine-based gas or a chlorine-based gas plasma. After being exposed to the chlorine-based gas or the chlorine-based gas plasma and then exposed to atmosphere, the material surface of the corrosion resistant member is immune to moisture absorption. Accordingly, the surface exposed to the chlorine-based gas or its plasma can be prevented from producing chloride particles from the corrosion resistant material. Further, since the base material of the member exhibits no liquid property causing corrosion of the material even when the member is cleaned with an aqueous solution, the base material can be avoided from being damaged with the aqueous solution, thus avoiding degradation of a corrosion resistance performance.  <P>COPYRIGHT: (C)2007,JPO&INPIT

Title: Power converter
Inventor: OZEKI YOSHIHIKO
IPC: H02M1/00
Filed: 2005-10-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a power converter which can reduce the turn-off loss more than conventional one while suppressing the rise of off-surge voltage.  <P>SOLUTION: In the power converter which uses an IGBT as a switching element, the magnitude of external resistance is set to 2 Ω or over but less than 9 Ω, in case that an IGBT has such a property that turn-off loss decreases and besides off-surge voltage increases when the magnitude of external resistance is reduced from 20 Ω to 9 Ω and that the magnitude of turn-off loss decreases and besides off-surge voltage decreases when the magnitude of external resistance is reduced from 9 Ω to 2 Ω, in changing the magnitude of the external resistance of a gate. Hereby, as compared with the case of setting the magnitude of external resistance to 9 Ω or over, it can generate dynamic avalanche phenomena more at turn-off of the IGBT, consequently it can reduce the turn-off loss more than conventional one while suppressing the rise of off-surge voltage.  <P>COPYRIGHT: (C)2007,JPO&INPIT
