Title: Method and apparatus for processing ceramic components
Inventor: GILGEN RALF DR
IPC: B01D53/96
Filed: 1998-07-28
Granted: 2000-04-11
Abstract: The invention  relates to a method and apparatus for porcessing ceramic components, mainly ceramic catalysts used in denitration plants. In said plants, the catalysts are impinged upon by low frequency sound. This enables the surfaces of the catalysts to be cleaned and simultaneously enhances their efficacy. If the catalysts cannot be reactivated they are subjected to final intensive cleaning wherein they are exposed once more to low frequency sound. Subsequently, the catalysts are crushed and the ceramic material can be used in all cases where the chemical properties of the material are of no particular significance. The cleaned particles containing pollutants are dumped or disposed of in melting chamber furnaces.

Between the main body and tapered thread-forming zone is located an additional thread forming zone having an axial length of approximately one thread pitch and a cross section that conforms to the high out-of-round of the tapered zone. The maximum diameter (at the lobes) of the additional thread-forming section approximately matches that of the full-diameter main body section. A lower-diameter stabilizing section can be provided ahead of the tapered zone, adjacent the tip of the fastener.

Title: Electrostatic protection circuit and semiconductor integrated circuit using the same
Inventor: HASHIMOTO MASAMI
IPC: H01L27/02
Filed: 2000-01-19
Granted: 2001-11-11
Abstract: The electrostatic protection circuit of the present invention is composed of the followings: the first power source terminal 1, which applies the first voltage; the second power source terminal 2, which applies the second voltage lower than the first voltage; the first diode 12, which is connected between the first and the second power source terminals in a reverse direction; and the second diode 11, which is connected between the first and the second power source terminals in a forward direction. Thus, for the static electricity that has the charges having an arbitrary polarity between the positive and the negative polarities, and is added between the first and the second power source terminals, one of the first and the second diodes must be in the forward direction. Therefore, the charges generated due to the static electricity are quickly absorbed and eliminated by the diode that has a forward direction for the charges.
