Title: Artificial dental root implant with a buffer
Inventor: PAN YUH-MIN
IPC: A61C13/10
Filed: 1997-02-12
Granted: 1998-05-01
Abstract: An artificial dental root implant with a buffer includes: A fixture; A base installed on the fixture; A cap installed on the base; An abutment cylinder on the cap; A screw for anchoring the abutment cylinder in the cap or the fixture; The features are: An elastic buffer installed between the fixture and the base; A central post installed at the center of the hole of the fixture; A reserved space between the bottom of the central post and the bottom in the fixture; The aforementioned components are assembled in such a relative position that part of the occlusion force applied on the artificial tooth that is supported by the artificial dental root can be absorbed by the elastic buffer surrounding the central post. The fixture is thus buffered and will not transmit a direct impact stress on the teethridge bones such that the possibility for the teethridge bones to absorb the impact stress is reduced. Moreover, the elastic buffer provides the central post with some elastic buffer function that is similar to the effect of teethridge membrane ligament of a natural tooth such that the occlusion relationship between the upper and lower teeth tends to be more balanced; The characteristics of elasticity and buffer are that the components are fixed by the central post and the buffer, and the buffer provides elasticity and surrounds the central post such that the central post is held at the uppermost position and a space is reserved between the central post and the bottom in the fixture.

Granted: 2000-05-11
Abstract: A method for inspecting wafer defects comprises an amount and a location of particle distribution on a blank wafer. A photoresist layer is covered on the blank wafer. A photolithography process is performed on the photoresist layer for the photoresist layer. The patterned wafer is scanned. The location of wafer defects can be found by comparing thepattern and color matching on the wafer. The amount of wafer defects is also counted.

Title: Back extrusion process for forming a manifold port
Inventor: INSALACO JEFFREY L
IPC: B21C37/29
Filed: 1998-03-24
Granted: 2000-10-11
Abstract: A method for forming ports on a heat exchanger manifold, in which risers are back extruded in a single operation from the surrounding material of the manifold such that subsequent machining steps to further define and finish the port are unnecessary. The method of this invention generally includes forging the manifold between a pair of die halves so as to back extrude a localized portion of the manifold into a riser cavity in one of the die halves. Afterwards, and while the manifold remains within the die cavity, a punch is forced through the riser cavity and into the extruded portion in a direction toward the manifold so as to further back extrude the extruded portion. This step causes the raised portion to flow in a direction opposite to the direction of the punch, producing a riser having an internal bore defined by the punch and an outer surface defined by the cavity. An internal chamfer can be simultaneously formed on the internal bore of the riser in order to facilitate assembly of a tube with the riser. The precision of the punch operation yields risers that do not require further machining or finishing to correctly size the risers or form the chamfers.

Abstract: The present invention relates to a construction method and apparatus about placing and arranging reinforcement. First set a bottom base on the ground in a predetermined forming on the simulated spot where the floor walls are to be built. Then construct a main frame surrounding the bottom base. Set a a top base upon the main frame, and have the top and the bottom distanced relatively. Place vertical reinforcement between top and bottom bases and secure the vertical bars on the top. After spacing the transverse reinforcement at intervals upon other base bearby, erect that base and tie up the transverse vertical reinforcement and then remove that base from the wall reinforcement constructed with vertical and transverse bars. Operate crane to lift up the main frame to depart the wall reinforcement fropm the bottom base, and move the frame with the top base onto the certain floor. Then, remove the wall reinforcement off the top base and upright onto the floor. Finally, let the crane hang back the main frame and the top base. This off-site reproducing process, which vertical and transverse reinforcement may be arranged and placed rapidly, could construct easily, save labor, and reduce the working period.

Title: Mixed frequency CVD process and apparatus
Inventor: RAOUX SEBASTIEN
IPC: H01J37/32
Filed: 1998-11-27
Granted: 2000-10-01
Abstract: A substrate processing system that includes a ceramic substrate holder having an RF electrode embedded within the substrate holder and a gas inlet manifold spaced apart from the substrate holder. The gas inlet manifold supplies one or more process gases through multiple conical holes to a reaction zone of a substrate processing chamber within the processing system and also acts as a second RF electrode. Each conical hole has an outlet that opens into the reaction zone and an inlet spaced apart from the outlet that is smaller in diameter than said outlet. A mixed frequency RF power supply is connected to the substrate processing system with a high frequency RF power source connected to the gas inlet manifold electrode and a low frequency RF power source connected to the substrate holder electrode. An RF filter and matching network decouples the high frequency waveform from the low frequency waveform. Such a configuration allows for an enlarged process regime and provides for deposition of films, including silicon nitride films, having physical characteristics that were previously unattainable.
