  • Publication number: 20110316224
    Abstract: A recording apparatus includes a slider that has a cam face with which a cam of the stopper comes into sliding contact and moves in the insertion direction from a first position to a second position with a resistance when the cassette is inserted into the mounting unit. The cam face includes a first cam face on which the cam slides when the slider moves from the first position to the second position and a press cam face against which the cam presses when the paper sheet comes into contact with the stopper. The press cam face has an inclination relative to a reference straight line which is perpendicular to a plane parallel to the insertion direction of the cassette which is greater than that relative to a straight line which extends from the contact point between the press cam face and the cam to the shaft.

  • Publication number: 20110187050
    Abstract: A sheet material transport apparatus includes a second planetary gear engaging with a transmission gear and providing planetary motion around the transmission gear. The second planetary gear is in a second separated position not capable of engaging with a first planetary gear during forward-direction rotation. The transmission gear engages with the first planetary gear and rotates in a direction that causes a second transport roller to rotate in the forward rotation direction, and positioned to engage with the first planetary gear that is positioned in a first engaging position during reverse rotation. A load is placed on the transmission gear by the second transport roller. The transmission gear rotates in the opposite direction to the forward-direction rotation. The second planetary gear applies a force on the first planetary gear in the direction that separates the first planetary gear from the transmission gear due to rotation.

  • Patent number: 7744769
    Abstract: The invention relates to a gas for removing deposits by a gas-solid reaction. This gas includes a hypofluorite that is defined as being a compound having at least one OF group in the molecule. Various deposits can be removed by the gas, and the gas can easily be made unharmful on the global environment after the removal of the deposits, due to the use of a hypofluorite. The gas may be a cleaning gas for cleaning, for example, the inside of an apparatus for producing semiconductor devices. This cleaning gas comprises 1-100 volume % of the hypofluorite. Alternatively, the gas of the invention may be an etching gas for removing an unwanted portion of a film deposited on a substrate. The unwanted portion can be removed by this etching gas as precisely as originally designed, due to the use of a hypofluorite. The invention further relates to a method for removing a deposit by the gas.

  • Patent number: 7649822
    Abstract: A recording/reproducing apparatus is provided which can write continuously a file of large-capacity at high-speed. A record area of HDD is provided with a disk cache area for temporarily storing data to be written. The disk cache area is defined as a area that is not used by a host apparatus (3) in an LBA space, and the disk cache area is disposed in an area with a high transfer rate such as an outer circumferential area of a disk (10). A file transferred from the host apparatus (3) is written in the disk cache area, and the file is transferred from the disk cache area to a usual user area during an idle period to release the disk cache area and prepare for next transfer data write.

  • Publication number: 20090327598
    Abstract: Disclosed is a disk storage apparatus to control writing to a storage medium having a storage area to which a first address space is allocated and whose transfer rate spatially changes, including a command reception section and control section. The command reception section receives a write command from a host apparatus and containing an address of the first address space. The control section performs control to divide the storage area into zones, pre-define a second address space where blocks are successively allocated to the zones from a beginning address of the first address space, replace, for each of the write commands received by the command reception, an address of the first address space contained therein with an address of the second address space, select one of the zones as a write target zone by cyclical changing, and perform a writing process to the storage medium for each selected zone.

  • Patent number: 7472219
    Abstract: A data-storage apparatus, a data-storage method and a recording/reproducing system are provided, which effectively use the time elapsing before data is transferred to be written in a recording medium, such as disc-seeking time and disc-rotation standby time, thereby to raise the speed of transferring data. A hybrid storage apparatus has two storage areas, i.e., a disc and a nonvolatile solid-state memory. The disc and the memory have a disc cache area, a system area, and a user area each. If data is transferred from the host apparatus, it is written into the cache area of the nonvolatile solid-state memory that can be accessed at high speed for the first super cluster. While the data being so written, the head is moved to a prescribed position. Any data coming after the head is moved to this position is written into the cache area.
