摘要:
A process for preparing carbon fibers including electrolyzing a carbon fiber in an alkaline aqueous solution, or electrolyzing a carbon fiber in an acidic aqueous solution followed by washing with an alkaline aqueous solution, and then applying a sizing agent of an aliphatic compound with multiple epoxy groups or an aromatic compound with multiple epoxy groups in which the number of atoms between the epoxy groups and an aromatic ring is 6 or greater. Alternatively, the carbon fibers are prepared by electrolyzing a carbon fiber in an aqueous solution of an ammonium salt and then applying a sizing agent of an aliphatic compound with multiple epoxy groups or an aromatic compound with multiple epoxy groups in which the number of atoms between the epoxy groups and an aromatic ring is 6 or greater.

An imaging device includes: an imaging unit that images a subject with three or more kinds of exposures, ratios of respective pairs of exposures of which adjacent to each other in an ascending order or a descending order are equal; and a combining unit that combines, on the basis of the ratios, pixel signals corresponding to the respective three or more kinds of exposures obtained by imaging the subject with the imaging unit.

A PON system capable of utilizing the bandwidth of an optical transmission channel in the PON section. In a PON system including an OLT and a plurality of ONUs, the OLT has: a downstream frame processing unit that removes at least part of the header information in a layer 2 header from a downstream frame received from a wide area network, and converts the remaining frame portion into a frame having a header specific to the PON section; and a downstream frame processing unit that extracts a downstream frame portion to be transferred to a user terminal, from a received frame from a PON, and adds the layer 2 header information deleted in the OLT.

An image processing system and a projector project a calibration image onto a projection target, sense the calibration image to generate sensing information, and generate projection target region information based on the sensing information. The system and projector generate projection area information based on the sensing information, image distortion correction information based on the projection target region information and the projection area information, and correct an image signal based on the image distortion correction information so that image distortion is corrected. The system and projector project an image based on the image signal corrected by the distortion correction section, determine a first height/width ratio that indicates a height/width ratio of the projection target, generate the image distortion correction information to display an image at a first height/width ratio range and display an image at a desired height/width ratio when the first height/width ratio is not within the acceptable range.

An image processing system including: a distortion correction section which corrects an image signal so as to adjust image distortion; an image projection section which projects an image based on the image signal; a sensing section which senses the projected image along an optical axis which does not coincide with an optical axis of the image projection section in order to generate sensing information; an image analysis section which generates edge point information and brightness index value distribution information, based on the sensing information, the edge point information showing a position of a predetermined edge point of the projected image in the sensed image, and brightness index value distribution information showing a distribution of brightness index values of the projected image; and a correction information generation section which generates projection distance information which shows a projection distance, based on the edge point information, and generates correction information for correcting the image signal, based on the projection distance information and the brightness index value distribution information.
摘要:
Provided is an ONU that suppresses transmission of a useless multicast control message to a PON section and enables a communication bandwidth of the PON section to be effectively used. The ONU of the PON system has a multicast group management table that shows a correspondence between a multicast group identifier and an address of a user terminal participating in a multicast group. When the ONU receives a request message of participation in the multicast group from the user terminal, the ONU registers the correspondence between the multicast group identifier indicated by the received message and the user terminal address. A new received message is deleted without being sent to the OLT if another user terminal address is registered already, along with a correspondence with the same multicast group identifier, in the multicast group management table.

摘要:
Pharmaceutical compositions containing adrenomedullin antagonist peptides, DNA, RNA compounds inhibitory on adrenomedullin activity, resulting in the efficient blockade of the induction of macroangiogenesis or vasculogenesis of more than 8 μm (in case of murine models), suppress the proliferation of cancer cells due to that inhibitory effect and suppress the protective activity of adrenomedullin. Accordingly, the pharmaceutical compositions of the present invention described herein can be used to treat various cancers, including, but not limited to, stomach cancer, colorectal cancer, lung cancer, ovarian cancer, liver cancer, and pancreatic cancer. Pharmaceutical compositions containing adrenomedullin expression vectors described herein induce macroangiogenesis and, accordingly are effective in treating cardiovascular and renal diseases such as congestive heart failure, myocardial infarction, hypertension, chronic renal failure, stroke, diabetes mellitus, and septic shock.
