Abstract: A susceptor assembly for supporting a crucible during a crystal growth process includes a susceptor base, a tubular sidewall connected to the susceptor base, and a removable sacrifice ring interposed between the susceptor base and the sidewall. Each of the susceptor base and the sidewall is formed of a carbon-containing material. The susceptor base has an annular wall and a shoulder extending radially outward from an outer surface of the annular wall. The sidewall has a first end that receives the annular wall to connect the sidewall to the susceptor base. The sacrifice ring has a first surface that faces the outer surface of the annular wall, a second surface that faces an interior surface of the sidewall, and a ledge extending outward from the second surface that engages the first end of the sidewall.

Abstract: A wheel rim processing machine which includes an oscillating table rotation base. A workbench is provided on an extending section of the oscillating table rotation base. A power source is provided on the work bench. A connecting element is connected to the workbench for connecting a power cylinder provided at a bottom side thereof and a plurality of gripping jaws lined with a griping jaw arrangement at a top side thereof. The connecting element is provided with an outer gear. The retaining arrangement on the connecting element has a connecting rod shaft element which is penetratedly fastened to the gripping jaw arrangement via pin elements. A block, which is provided below the connecting element at an inner side thereof, is connected to a pivot connecting element connected which retains the power cylinder below the connecting element via at least one screw element.

Abstract: A foldable support base includes a first board, a second board, and a third board. The first board has an edge forming a positioning section. A surface of the first board and a surface of the positioning section of the first board are provided with a first pad for protection against scratching. The second board has an edge that is in movable pivoting joint with an opposite edge of the first board. The third board has an edge that is in movable pivoting joint with an opposite edge of the second board. The second and third boards are provided with at least one second pad to protect against scratching and to prevent undesired movement. The above described arrangement helps, in either expanded or folded condition, reducing overall volume for easy carrying and protecting against damage caused by scratching and also providing a function of secure positioning and retention.

Abstract: A keyboard to be an inside page of a notebook comprises a main body on which a keyboard region, an electronic region having a transmission device mounted therein, a mounting region having a liftable cover mounted thereon, and a connection part are mounted. A top plate is pivotally connected to the top edge of the cover. After lifting up the cover, the bottom edge of the top plate is leant against a supporting surface for providing the mounting region with a more powerful supporting force for steadily mounting a hand-held electronic apparatus. The connection part comprises through holes corresponding to the loose-leaf binders in positions. By means of the keyboard region of the main body, the data are inputted into the hand-held electronic apparatus. The keyboard can couple with any notebook having the loose-leaf binders mounted therein through the connection part of the main body to facilitate carry.

Abstract: A notebook type keyboard apparatus is disclosed. The apparatus comprises a keyboard coupled to a main body in the form of a notebook. Containing slots for firmly receiving a PDA or mobile phone are mounted on the keyboard. The handheld electronic apparatus is connected to a wireless transmission apparatus on the keyboard for inputting data. The main body comprises a bottom plate and a cover plate of the support rack mounted on its outside. The cover plate can be folded against the bottom plate, or unfolded for operation on a planar surface by the support of the support rack, so that the main body is treated as a support framework of input operation. Notepapers are mounted in the main body below the keyboard for handwriting the record. Therefore, an integrated data input apparatus is provided. It is easy to fold and set up this apparatus. When it is not in use, it conserves space, and is portable.

Abstract: An external keyboard structure for connecting a keyboard or various handheld devices by a wireless signal or a connector, and then used as a keyboard structure for storing or driving the whole keyboard; such a structure comprises a folding base; an adjusting device disposed on the folding base and corresponsive to the keyboard; and an accommodating area disposed between the folding base and a keyboard.
