Patents by Inventor Takuya Arimura

Takuya Arimura has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10916032
    Abstract: According to the present disclosure, for example, when a line of a character as an object is to be thickened, an enlargement process is performed. Then, a correction process is performed to deform the line of the character into a moderate thickness. Moreover, when a line of a character as an object is to be thinned, a reduction process is performed. Then, a correction process is performed to deform the line of the character into a moderate thickness. Also for a hollow character as an object, a similar contour process is performed to deform the line of the hollow character into a moderate thickness.
    Type: Grant

  • Patent number: 7429439
    Abstract: An electrophotographic photoreceptor of excellent durability having high sensitivity and light responsiveness, not suffering from lowering of the electric characteristics by exposure to light, change of circumstance, or repetitive use, and excellent in the cleaning property and not suffering from lowering of the picture quality of formed images for a long times, in which an enamine compound represented by the general formula (1), for example, an enamine compound represented by the following structural formula (1-1) is incorporated in a photosensitive layer 14, and the surface energy (?) on the surface of the photosensitive layer 14 is set to 20.0 mN/m or more and 35.

  • Patent number: 6985468
    Abstract: The memory circuit of the present invention temporarily stores information symbols included in a reception signal according to a CDMA system which allows multi-code communication to carry out coherent detection using a pilot symbol. The memory circuit of the present invention is constructed of a plurality of electrically independent memory blocks. Each memory block corresponds to one code and one slot of an information symbol. Write access and read access to memory blocks are generated periodically on condition that write access and read access to one memory block do not occur simultaneously. Blocks to which no access is generated are forcibly set to a low power consumption mode to reduce power consumption caused by accesses.

  • Publication number: 20050287455
    Abstract: An electrophotographic photoreceptor having good electric properties such as chargeability, sensitivity and responsibility, having good oxidizing gas resistance, and having good property stability in that the good electric properties thereof do not worsen in repeated use, is provided. An undercoat layer is provided between the conductive support and the photosensitive layer of an electrophotographic photoreceptor, and the undercoat layer contains an amine compound expressed by the following formula (1) added thereto.
