Abstract:
An image forming apparatus includes; an image forming unit; an annular belt that moves circularly; a detection unit that detects a state of a surface of the belt; and a tension increase unit that increases a tension of the belt, at a detection position by the detection unit, when detection is performed by the detection unit, as compared with the tension of the belt before detection at the detection position is performed by the detection unit.
Abstract:
Disclosed is a carbon nanotube field effect transistor which stably exhibits excellent electrical conduction properties. Also disclosed are a method for manufacturing the carbon nanotube field effect transistor, and a biosensor comprising the carbon nanotube field effect transistor. First of all, an silicon oxide film is formed on a contact region of a silicon substrate by an LOCOS method. Next, an insulating film, which is thinner than the silicon oxide film on the contact region, is formed on a channel region of the silicon substrate. Then, after arranging a carbon nanotube, which forms a channel, on the silicon substrate, the carbon nanotube is covered with a protective film. Finally, a source electrode and a drain electrode are formed, and the source electrode and the drain electrode are electrically connected to the carbon nanotube, respectively. A field effect transistor manufactured by these processes stably exhibits excellent electrical conduction properties since the carbon nanotube, which serves as the channel, is not contaminated.

Abstract:
A relay device 40, when it relays data blocks transmitted in succession from a transmitter device 20 to a receiver device 10, is caused to identify a state code showing a state of a communication resource used when the data blocks are transferred. Relay device 40 divides the identified state code into portions of a predetermined data size and writes the divided portions into a predetermined area of the data blocks. Receiver device 10 transmits to transmitter device 20 an acknowledgement containing the same data as is written in a predetermined area of the received data block. Transmitter device 20, upon receipt of the acknowledgement, reads the state code that is divided and written in the acknowledgement and increases or reduces the number of data blocks on the basis of the state code.
Abstract:
An image-forming device has an image-forming unit, a toner density detection unit, a reflective shutter, a storage unit, and a control unit. The control unit calculates a correction value for correcting the output value to control an image-forming unit according to the correction value. The image-forming unit forms a reference toner image on the image-carrying member. The toner density detection unit receives a reflected light beam from the reflective shutter positioned at the shielding position to generate a first output value, the first output value being stored in the storage unit. The toner density detection unit receives another reflected light beam from the reference toner image to generate a second output value when the reflective shutter is positioned at the retracted position, the second output value being stored in the storage unit. The control unit calculates a ratio of the second value and the first value and then calculates the correction value based on the ratio.

Abstract:
Upon receiving an acknowledgement after retransmission of a data segment, an acknowledgement number contained in the acknowledgement is compared with an acknowledgment number expected to be contained in an acknowledgement pertaining to the retransmitted data segment. When the former is larger than the latter, it is determined that the acknowledgement pertains to a data segment that was originally transmitted.
Abstract:
There is provided a flat transmission belt that suppresses occurrence of cracks in the belt surfaces to extend the life of cover rubber layers and hence the life of the belt as a whole. A flat transmission belt of the present invention has a first cover rubber layer and a second cover rubber layer formed on a side of the belt opposite to the side on which the first cover rubber layer is formed, and is wound between driving and driven pulleys when in use. The first cover rubber layer and the second cover rubber layer are respectively formed of rubber materials that are of the same kind but differ in mixing ratio of the components thereof, and the first cover rubber layer, which contacts a smaller number of the driving and driven pulleys, has an extension ratio higher than the extension ratio of the second cover rubber layer, which contacts a larger number of the driving and driven pulleys.
