Abstract: An image processing device includes a judgement section and a generation section. A latent image, which would be retained or eliminated by photocopying, is to be superposed with machine-readable code images, which are encoded supplementary information, to generate a superposed image. The judgement section judges overlapping of the latent image with the machine-readable code images. The generation section, on the basis of judgement results from the judgement section, determines an arrangement of the machine-readable code images and generates the superposed image.

Abstract: In the breakdown preventive mechanism of a rotary damper of the invention, when the upper rotor (12) is rotated in one direction, a communication path is formed between the valve body (16) and the lower rotor (15), and the pressure in the pressure chamber is formed between the lower rotor and the lower housing (17) is lowered, and rotation is easily performed. In the breakdown preventive mechanism of a rotary damper, when the upper rotor (12) is rotated in other 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 (13) and the relief valve (14) by resisting the elastic element (19), and thereby prevents breakdown of the rotary damper.

Abstract: Embodiments of the present invention help to improve test processes for hard disk drives (HDDs) and increase the manufacturing efficiency of HDDs. According to one embodiment, a test process performs a test on an HDD with respect to a plurality of items and stores one or a plurality of test results. Moreover, it determines the optimum specification category to which the HDD is to belong based on the stored test results. One factor of the specifications—storage capacity—has been determined before the test process or is determined during the test process. The test process classifies HDDs with the same storage capacity into different specification categories, and this classification may be performed in a single test process. This achieves efficient manufacture of HDDs with different specifications corresponding to the diversified usage of HDDs.

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.

Abstract: Embodiments of the invention improve the cache hit ratio of read data. A hard disk drive (HDD) according to an embodiment of the present invention determines whether the read buffer should be used in its entirety or the partial continuous space should be used to read read-data from the magnetic disk. When the HDD determines use of the partial continuous space, the HDD specifies the sub-buffer which is a continuous space wherein the leading-end position and the trailing-end position are coupled to each other, and executes data writing to the sub-buffer in parallel with data reading from the sub-buffer and transmission thereof to the host. The sub-buffer capacity coincides with the data length of the back data.

Abstract: An optical fiber sensor can be interposed between a bumper reinforcement and a load transmitting plate to extend in the direction of width of a vehicle along with the bumper reinforcement. In this case, when a change does not occur substantially in an immediately previous predetermined period in an output voltage of a light emission amount of the optical fiber sensor, a feedback control is performed in such a way that the change becomes a level of zero of the output voltage of the optical fiber sensor. In contrast, when a change in the output voltage is not substantially zero, the immediately previous state of emission of light is maintained. Accordingly, it is possible to effectively compensate a zero point shift caused by a temperature change or/and an aging degradation of the optical fiber sensor.
