An image forming apparatus is provided that includes urging members provided at first and second ends in an axial direction of at least one of rollers around which an endless belt is wound, so as to urge the at least one roller and apply a tension to the endless belt. The urging members include a first urging member for applying a first moment about a middle point of a contact portion of a predetermined one roller in the axial direction and a second urging member for applying a second moment about the middle point. The second moment is different from the first moment such that a first-side portion, where a guide is provided to fit into a groove formed on at least one roller, of the endless belt with respect to the middle point is extended by a same length as a second-side portion of the endless belt.

Disclosed is a novel packing for a solar cell module laminator. An object is to solve the problem of durability involved in conventional packings and to stably manufacture a high-quality module over a long period of time. The packing is composed of an olefin based rubber crosslinked with an organic peroxide and allowed to have a Shore A hardness, a dimensional stability, and a compression set each falling within a certain range. The olefin based rubber is suitably an EPDM rubber and/or an EPM rubber and is made possible for achieving extrusion molding.

The present invention relates to a thermoplastic resin composition which comprises 100 parts by weight of a polyamide resin (component A) and 1 to 400 parts by weight of a granular inorganic filler (component B) comprising an inorganic filler having an average particle diameter of 0.01 to 100 μm and a water-soluble polyester resin binder, and having a bulk density of 0.4 to 1.5 g/mL; and a resin molded article obtained by molding the thermoplastic resin composition. The thermoplastic resin composition is improved in various properties such as extrusion moldability, rigidity, impact resistance, thermal stability and hue, and exhibits an excellent balance between these properties.

A relay apparatus compresses an information amount of channel quality information notified from a plurality of terminal apparatuses to notify a control station apparatus, and thereby improves spectral efficiency. The relay apparatus 400, which is applied to a communication system in which a control station apparatus and a terminal apparatus perform wireless communications using a plurality of sub-channels and relays the communications between the control station apparatus and the terminal apparatus, has a receiving section 402 that receives channel quality information indicative of channel quality of sub-channels from the terminal apparatus, a compressing section 405 that compresses an information amount of the received channel quality information and that generates notification information to notify the control station apparatus, and a transmitting section 406 that transmits the generated notification information to the control station apparatus.

Provided is a communication system that can allocate resources on an uplink for a CQI report, and can reduce the overhead of the CQI relay transmission from a relay station apparatus to a base station apparatus. To each mobile station apparatus (501, 502) that transmits CQI directly to a base station apparatus (500), resource blocks on a base station apparatus uplink to be used for the transmission of each CQI to the base station apparatus are allocated. To each mobile station apparatus (511 to 513, 521 to 524) that transmits CQI to the base station apparatus via each relay station apparatus (510, 520), resource blocks on a relay station apparatus uplink to be used for the transmission of each CQI to the relay station apparatus are allocated. Resource blocks on the base station apparatus uplink to be used for each relay station apparatus to relay-transmit to the base station apparatus the CQI received from the mobile station apparatus are allocated on the basis of the allocation result of the resource blocks on the relay station apparatus uplink for each relay station apparatus.

A connector cover (10) has of two half pieces (20, 30) mounted on a rear of a connector housing (51). Upper and lower ribs (20U, 20L) are formed in one half piece (20) near a rubber plug (60) mounted in a rear end portion of the connector housing (51) at opposite sides of an extension (L) of the axial line of a through hole (61) of the rubber plug 60, through which hole a wire (W) is inserted. The upper and lower ribs define a first wire guide (22) to bend small-diameter wires (W1) drawn out backward from the through hole (61). The connector cover (10) also has a second wire guide (23) for bending the small-diameter wires (W1) bent by the first wire guide (22) in a direction opposite to a bending direction by the first wire guide (22).
摘要:
A thermal type flow sensor includes a base portion provided along the direction of a fluid flowing through a main passage, and a sensor element mounted on the base portion and having an exothermic resistor formed on a substrate for detecting the fluid flow rate. The base portion has a rectangular recessed portion in which the sensor element is fixed so that the surface of the detecting portion of the sensor element is positioned lower than an upper edge of the recessed portion. A wall portion of the measuring passage facing the sensor element is constricted. The exothermic resistor is disposed along the fluid passage and spaced away from the upstream side upper edge of the recessed portion and cannot be substantially affected by a fluid flow disturbance due to a step portion formed between the upper edge of the recessed portion and the detecting portion surface.
