  • Patent number: 8096393
    Abstract: In the breakdown preventive mechanism of a rotary damper, when the upper rotor is rotated in one direction, a communication path is formed between the valve body and the lower rotor, and the pressure in the pressure chamber is formed between the lower rotor and the lower housing is lowered, and rotation is easily performed. When the upper rotor is rotated in another direction, the viscous fluid does not flow between the valve body and the lower rotor, and the pressure in the pressure chamber formed between the lower rotor and the lower housing is raised. As a result, the viscous fluid pushes down the relief valve and a cage type relief valve by resisting the elastic element, and thereby prevents breakdown of the rotary damper.

  • Patent number: 8009376
    Abstract: Embodiments of the present invention help to improve the capacity and the performance of a disk drive device. According to one embodiment, a data track pitch is set to each recording surface. The recording surfaces are divided into bands. A hard disk drive (HDD) sequentially moves a head to an adjacent data track in a band and performs a head switch at the band end in its data accessing. On a recording surface, the number of data tracks in each band is variable; and each band is constituted by different number of data tracks as necessary. The number of data tracks in each band is set so that the radial position of the band end comes close to the radial position of the corresponding band end on another recording surface. Accordingly, even if the recording surfaces have different variation rates of the data track pitch in the radial direction, increase in process time due to head switches can be suppressed.

  • Publication number: 20100243747
    Abstract: One information code unit is configured by a first module and a second module which are “red,” a third module which is “black,” a fourth module and a fifth module which are “white,” and a sixth module and a seventh module which are “black.” When the information code is read by first reading means such as a barcode reader, white or black binarization determination is performed. As a result, the code is recognized as “white, black, white, black,” as in the read result of a conventional monochromatic barcode. On the other hand, when the information code is read by second reading means such as a mobile phone camera, the “black” regions can be read as “black” and the “white” regions as “white,” while the “red” region can be differentiated from the “black” and the “white” regions. Thus, the information code can be utilized as a multi-signal information code.
