  • Publication number: 20080304106
    Abstract: An image processing apparatus comprises a transfer processing section, a plurality of image processing sections, and a control section. The transfer processing section is for transferring image data to a memory. The image processing section is for carrying out an image process with respect to image data, and writing, into the memory, the image data that has been subjected to the image process. The control section is for controlling the transfer processing section and the plurality of image processing sections. The control section includes: a selecting section that selects two or more processing sections from among the transfer processing section and the plurality of image processing sections; and an initialization control section that causes the processing sections selected by the selecting section to carry out an initialization process with respect to the memory. This makes it possible to carry out an initialization process with respect to the memory at a high speed, without causing an increase in cost.

  • Publication number: 20080266600
    Abstract: A print control apparatus includes a command section for causing a printing apparatus to execute a print job, the print job for printing a print subject image on a sheet, with a mark overlaying the sheet. Furthermore, the print control apparatus includes: an accepting section that accepts a processing condition for an image process of the mark, during a processing condition accepting period, which is set for every print job and is the period before an input of an executive instruction; and an image processing section that performs the image process of the mark in accordance with the processing condition during the processing condition accepting period. This makes it possible to prevent delay in initiation of printing, without excessive consumption of storage capacity of a storage device.

  • Publication number: 20070046286
    Abstract: Embodiments of the invention provide an inexpensive magnetic head tester employing component parts of a production HDD and capable of exercising functions very close to those of a production HDD. In one embodiment, a magnetic head tester employs the VCM actuator and the control circuit of a production HDD and has a lightweight, simple HGA fixing mechanism mounted on an actuator arm. The HGA fixing mechanism fixes an HGA to the actuator arm by a method using a very light holding spring mounted on the arm, a method of mechanically clamping an HGA by using air pressure, or a method of fixing an HGA to the arm by elastically deforming a rubber clamping member by air pressure. Servo control is achieved by the actuator of a production VCM. An end part of the VCM actuator is stopped by a stopping mechanism and is held by a holding spring to prevent the runaway of the VCM actuator. Servo control is performed by balancing the driving force of the VCM and the resilience of the spring.

  • Patent number: 7054610
    Abstract: In a cellular telephone provided with a receiving circuit of a direct conversion type, a passive low-pass filter is arranged between a mixer for an I-channel and a base band circuit for removing interference waves of or above a channel next to a channel neighboring to the I-channel, and another passive low-pass filter is arranged between a mixer for a Q-channel and the base band circuit for removing interference waves of or above a channel next to a channel neighboring to the Q-channel. Since the low-pass filters for removing the interference waves of or above the channel next to the neighboring channel are of a differential type, the circuit scale can be small, and the power consumption is small. Since the interference waves are removed by the passive low-pass filters and the active low-pass filters, only the desired channel can be reliably received.

  • Patent number: 6980610
    Abstract: A level of a base band signal at an input side of a variable gain amplification circuit is detected by a logarithmic amplifier having a wide input voltage range at a start of an operation, a control unit then performs a coarse feedforward control on a gain of the variable gain amplifier based on the detected level and finds a level of an output of an A/D converter by a mean square deriving circuit and inputs the resulting signal to the control unit. Then the control unit performs a fine feedback control on the variable gain amplifier based on the detected level.

  • Publication number: 20050179136
    Abstract: In a multi-layer substrate module receiving from an external earth node (20) supply of a reference potential (Vss) for grounding, a plurality of ground lines (170-1, 170-2, 170-3) are provided respectively corresponding to a plurality of internal circuits (210, 220, 230). Moreover, a common node (Ncmn) for coupling the ground lines (170-1, 170-2, 170-3) is provided in an insulating layer (105C) of the multi-layer substrate module. The common node (Ncmn) is electrically coupled to the earth node 20 through a ground pin terminal 204 shared by the plurality of internal circuits (210, 220, 230). Preferably, the common node (Ncmn) is provided in the lowest insulating layer of the multi-layer substrate module. Thus, parasitic inductance of the portion through which an earth current flows, that is, the portion common to the plurality of internal circuits (210, 220, 230), can be suppressed with a small number of ground pin terminals.

  • Publication number: 20050161798
    Abstract: The present invention relates to a semiconductor device and, more particularly, has for its object to provide a technique for improving the performance of a semiconductor device having a ground terminal and a plurality of signal terminals arranged around the ground terminal. To attain the object, the present invention features isolation between a ground terminal (5, 35) connected to a functional block (11) and a ground terminal (6, 36) connected to a functional block (12). Thus, a ground potential applied to one of the functional blocks through the corresponding ground terminal is prevented from varying depending on the magnitude of a current flowing through the other functional block. This improves the performance of each functional block to improve the performance of the semiconductor device.
