Abstract: An integrated circuit structure includes a first metal feature formed into a first dielectric layer, a second metal feature formed into a second dielectric layer, the second dielectric layer being disposed on said first dielectric layer, and a via connecting the first metal feature to the second metal feature, wherein a top portion of the via is offset from a bottom portion of the via.

Abstract: A method and system for inspecting deviation in dynamic characteristics of a feeding system are provided, and the method includes: exciting the feeding system and detecting vibrations of a subcomponent of a component to be inspected of the feeding system to generate a monitoring excitation signal in a monitoring mode; calculating, by a modal analysis method, monitoring eigenvalues and monitoring eigenvectors of the monitoring excitation signal; determining, by a modal verification method, similarity between the monitoring eigenvalues and standard eigenvalues of a digital twin model and similarity between the monitoring eigenvectors and standard eigenvectors of the digital twin model; determining that the dynamic characteristics of the subcomponent are deviated, when the monitoring eigenvalues and monitoring eigenvectors are not similar to the standard eigenvalues and standard eigenvectors. Therefore, the subcomponent whose dynamic characteristics are deviated can be sensed remotely and precisely.

Abstract: An apparatus for producing silicon carbide crystal is provided and includes a composite structure formed by a plurality of graphite layers and silicon carbide seed crystals, wherein a density or thickness of each layer of graphite is gradually adjusted to reduce a difference of a thermal expansion coefficient and Young's modulus between the graphite layers and silicon carbide. The composite structure can be stabilized on a top portion or an upper cover of a crucible made of graphite, thereby preventing the silicon carbide crystal from falling off.

Abstract: A pivot device includes first and second shafts. A first torque component unit is coupled to an end of the first shaft. A second torque component unit is coupled to an end of the second shaft. A positioning unit is coupled to another ends of the first and second shafts and includes a first positioning board, a second positioning board, and a positioning block. A first transmission unit is disposed between the first and second positioning boards. A second transmission unit is disposed between the second positioning board and the positioning block. Each of the first and second transmission units includes a wheel mounted on the first shaft, a cam mounted on the second shaft, and a sliding block movable between the wheel and the cam, with each sliding block selectively stopping the wheel or the cam to prevent rotation of the first or second shaft, providing multi-stage switching.

Abstract: A disc tray for a printing device includes a driving mover including a first guiding portion; a main body including a disc receiver having a holding portion and a sloping portion connected with each other, a second guiding portion engaged with the first guiding portion, and a third guiding portion, with the driving mover driving the main body by way of the first guiding portion and the second guiding portion to move the main body; and a supporter including a fourth guiding portion engaged with the third guiding portion to allow the fourth guiding portion to move along the third guiding portion. The supporter and the holding portion are used to support a printed disc. When the disc receiver receives the printed disc, the supporter is moved to be veiled under the main body for dropping the printed disc from the sloping portion of the disc receiver.

Abstract: A system and a method of controlling a processing device for automatically and continuously processing discs are disclosed. The method comprises: determining if a tray in a processing system is opened by adapting a first sensor; determining if any one of the discs is loaded in the tray by adapting the second sensor; in the event of the tray being opened and one disc being loaded, unloading the loaded disc by adapting a transporting device; in the event of the tray being opened and no disc being loaded, loading one disc by adapting the transporting device; and closing the tray for processing the one disc being loaded in the tray transported by the transporting device and controlled by the computer.

Abstract: A bridge device for a disk drive has the I/O terminals to which an external automatic controlling apparatus is connected, so the external automatic controlling apparatus directly controls a disk tray of the disk drive to move in or move out without a computer. In addition, the bridge device also further has a computer connecting port, to which the external computer is connected. The computer controls operations of the disk drive.

Abstract: A device and a method for automatically turning over a disc relate to a guide rod provided with a movable member. The movable member is assembled to a rotating member via a pivot member in such a manner that the movable member can axially move along and radially rotate around the guide rod. The pivot member is disposed between the movable member and the rotating member and powered to rotate. The rotating member is provided with a disc-carrying device in a direction of its rotation around the pivot member for taking the disc. The pivot member drives the disc to rotate via the rotating member, so as to turn over the disc, so that the rotating member makes the disc slide down into the tray in an inclined manner.

Abstract: A method for transporting discs, A disc transporting device and a drawer type disc transporting device are disclosed. The disc transporting device comprises a lifting mechanism, a swing mechanism and a control element, wherein the lifting mechanism further comprises a clipper element, a drive element and a rotational connection element, the swing mechanism further comprises a corresponding connection element and a swing rotation element. The clipper element can grab at least one disc. The drive element is coupled with the clipper element and drives the lifting mechanism. The rotational connection element engages with the drive element; the corresponding connection element of the swing mechanism corresponds to the rotational connection element to enable the lifting mechanism going up/down along the swing mechanism. The control element engages with the swing rotation element of the swing mechanism to control the swing mechanism.
