Patent number: 7156649Abstract: A fixed mold (10) has engaging pins (17) projecting towards a movable mold (20). Each engaging pin (17) includes a shaft (17A) and a large-diameter portion (17C) formed at the leading end of the shaft (17A). The large-diameter portions (17C) of the engaging pins (17) interfere with the bottom surfaces of recesses (53) of an ejector plate (50) in the process of separating the movable mold (20).

Patent number: 7147714Abstract: When a SiC substrate is heated up to around 1800°C., sublimation of SiC occurs from the SiC substrate. Moreover, temperature of the front surface of the SiC substrate is lower than that of the back surface of the SiC substrate. Therefore, sublimation gas sublimed from a back-surface vicinity of the substrate, where temperature is high, moves to a front-surface vicinity of the substrate, where temperature is low, through the hollow micro-pipe defect. Epitaxial growth proceeds on the front surface of the substrate while the sublimation gas is recrystallized at the front-surface vicinity of the substrate, so that the micro-pipe defect is occluded.Type: GrantFiled: April 27, 2004Date of Patent: December 12, 2006Assignee: Denso CorporationInventors: Masami Naito, Kazukuni Hara, Fusao Hirose, Shoichi Onda

Patent number: 7125242Abstract: A sprue bushing includes a melt channel for receiving a melt stream of moldable material from a source. The melt channel includes a first portion, a second portion and a decompression cavity located between the first portion and the second portion. A manifold having a manifold channel receives the melt stream from the melt channel of the sprue bushing and delivers the melt stream through the nozzle channels of several hot runner nozzles towards at least one mold cavity. A decompression device, which includes a rod having an enlarged head, is movable by an actuator to reciprocate within the decompression cavity between a retracted position and an extended position. Movement of the enlarged head from the extended position to the retracted position causes the suck back of the molten material in the hot runner nozzle and causes a portion of the molten material to be drawn toward the decompression cavity.Type: GrantFiled: August 11, 2003Date of Patent: October 24, 2006Assignee: Mold-Masters LimitedInventor: Neil Dewar

Patent number: 7108500Abstract: Within a process for recycling of PET-material and/or objects of PET, the PET-material to be processed is heated and dried in the course of a pre-treatment step and simultaneously is crystallized at elevated temperature. This pre-treatment step is followed by a main-treatment step under vacuum. In this main-treatment step, the processed material is again dried and crystallized at a temperature that is higher than the temperature of the pre-treatment step. Preferably, also in the main-treatment step no plasticizing of the material takes place; the plasticizing or, respectively, melting of the material takes place only after the main-processing step. An apparatus for performing this process comprises a pre-processing device (3) in which the processed material is dried and simultaneously crystallized at elevated temperature, and, if desired, is also comminuted.Type: GrantFiled: May 25, 2004Date of Patent: September 19, 2006Inventors: Helmut Bacher, Helmuth Schulz, Georg Wendelin

Patent number: 7105055Abstract: A single-wafer, chemical vapor deposition reactor is provided with hydrogen and silicon source gas suitable for epitaxial silicon deposition, as well as a safe mixture of oxygen in a non-reactive gas. Methods are provided for forming oxide and silicon layers within the same chamber. In particular, a sacrificial oxidation is performed, followed by a hydrogen bake to sublime the oxide and leave a clean substrate. Epitaxial deposition can follow in situ. A protective oxide can also be formed over the epitaxial layer within the same chamber, preventing contamination of the critical epitaxial layer. Alternatively, the oxide layer can serve as the gate dielectric, and a polysilicon gate layer can be formed in situ over the oxide.Type: GrantFiled: May 6, 2004Date of Patent: September 12, 2006Assignee: ASM America, Inc.Inventors: Armand Ferro, Ivo Raaijmakers, Derrick Foster
