Embodiments of the present invention help provide a simple and inexpensive actuator mechanism for a magnetic disk drive. The actuator mechanism includes an approximately circular coil and a simple shaped magnet, and is capable of displaying adequate performance required for the magnetic disk drive. According to one embodiment, the magnetic disk drive includes an actuator mechanism which has an approximately circular coil and an approximately rectangular magnet. The long axis direction of the rectangular magnet is oriented in parallel to a straight line connecting the center of the inner circle of the circular coil in a state in which the actuator is positioned at the outermost circumference of a data area and the center of the inner circle of the circular coil in a state in which the actuator is positioned at the innermost circumference of the data area.

A magnetic disk apparatus capable of reducing deformation of a magnetic disk is disclosed. The magnetic disk apparatus comprises a magnetic disk on which data is recorded while the disk is driven, a hub around which the magnetic disk is supported from an under side of the magnetic disk, and a clamp in contact with the other side of the magnetic disk and fixing the magnetic disk. An O-ring is interposed between a flange formed at an outer circumference of the hub and the magnetic disk, and a spacer is interposed between the magnetic disk and the O-ring. Thus an upper surface of the hub is in contact with an under surface of the clamp and defines a vertical position of the magnetic disk.

Toner remaining on a photosensitive drum may be prevented from being given out after a toner image is transferred, by causing a seal member to abut on both a photosensitive portion of the photosensitive drum and a flange disposed on each of ends of the photosensitive portion and having less hardness than the photosensitive portion, further a flange being configured to be smaller in outer diameter than the photosensitive portion so that a contact pressure of the seal member on the flange may be reduced, and accordingly, in an image formation apparatus, this may allow flange galling to reduce without seal characteristic degradation.

A method for forming a Ru layer for an integrated circuit by providing a patterned substrate in a process chamber, and exposing the substrate to a process gas comprising a ruthenium carbonyl precursor and a CO gas to form a Ru layer over a feature of the patterned substrate. In one embodiment, the CO partial pressure in the process chamber is varied during the exposing to control the step coverage of the Ru layer over the feature. In an alternative or further embodiment, the step coverage can be controlled by varying the substrate temperature during the exposure.

A method for depositing a thin film on a substrate in a vapor deposition system is described. Prior to the deposition process, the substrate is provided within the vapor deposition system and coupled to an upper surface of a substrate holder within the vapor deposition system, whereby the substrate is heated to a deposition temperature in a first gaseous atmosphere. Thereafter, the first gaseous atmosphere is displaced by a second gaseous atmosphere, and the pressure is adjusted to a deposition pressure. The second gaseous atmosphere comprises a gaseous composition that is substantially the same as the carrier gas utilized to transport film precursor vapor to the substrate and the optional dilution gas utilized to dilute the carrier gas and film precursor vapor.

In a ladder-type piezoelectric filter, attenuation in stop bands on a low frequency side and a high frequency side are increased while a pass band is widened. The ladder-type piezoelectric filter is made up by alternately connecting parallel arms and series arms. The parallel arms are respectively made up by serially connecting parallel resonators and LC element networks, and the series arms are respectively made up of series resonators. The LC element networks are respectively made up so as to be inductive in resonant frequencies of the serially connected parallel resonators. Further, the LC element networks include capacitors which contribute to formation of a new series resonant point in the stop band on the high frequency side.

An image forming apparatus for forming an image on a recording medium is disclosed. The image forming apparatus includes a print head (4) having an ink emitting surface (6) in which there are formed a plural number of ink emitting openings (13). An ink is emitted from the ink emitting openings (13) for forming an image on a recording medium. The image forming apparatus also includes an emission controller (41) for controlling the ink emission from the ink emitting openings (13) formed in the ink emitting surface (6). The emission controller (41) is responsive to an input image signal to control the quantity of preliminary ink emission from one or more of the ink emitting openings (13) or to select one or more of the ink emitting openings (13). In this manner, the quantity of the preliminary ink emission from the ink emitting openings (13) is controlled, or one or more of the ink emitting openings (13) is selected, responsive to the image signal, to diminish the wasteful ink emission and to clean the ink emitting openings (13) or the vicinity without damaging the ink emitting surface (6).

A novel method and apparatus is disclosed, that embeds with, or otherwise makes available to an adaptive equalizer, suitable for use in IEEE 10G-LRM standard compliant receivers, digital logic that monitors some of the Layer 1 and preferably some of the Layer 2 processing that typically occurs after the equalization step during decoding and processing of the record data stream. From this additional logic information, the equalizer is able to make a much more accurate prediction of equalizer convergence by counting processing errors and prove convergence by calculation of BER. The novel method and apparatus are applicable to ASIC embodiments and the complexity of the logic information obtained can be programmably scaled back or enhanced as appropriate in light of the particular communication environment.
