摘要:
A pneumatic radial tire has a nominal section width of 255 mm or more, and an outer diameter of 720 mm or more. At least one carcass layer is constructed between paired right and left bead cores with the two end portions of the carcass layer being folded back from the inside to the outside of the tire around the respective bead cores in a way that their corresponding bead fillers are enclosed in the two folded end portions thereof. The length of each bead filler in the radial direction of the tire is 5% to 20% of the section height of the tire. The carcass layer is formed of organic fiber cords each made of at least one type of organic fiber which has an expansion ratio of 1% to 5% when a load of 2.0 cN/dtex is applied to the organic fiber. A sheet-shaped rubber reinforcement layer with a thickness of 0.5 mm to 2 mm, whose rubber has a larger rigidity than that of the sidewall section, is interposed between the carcass layer and a sidewall section on each side of the tire.

A rotation detecting device for detecting the rotational speed of a gear in a transmission without increasing the width of the gear in the axial direction, using any expensive sensor and not limiting the location of a shift drum. An internal combustion engine includes a crankcase in which a crankshaft and a transmission are accommodated. The transmission includes a plurality of gears for shifting, an input shaft for inputting a rotational drive force from the crankshaft, and an output shaft wherein the rotational drive force is transmitted from the input shaft through the gears and to the output shaft to a drive wheel. The internal combustion engine includes rotation detecting devices for respectively detecting the rotational speeds of the gears. The rotation detecting devices respectively include detecting portions opposed to the gears rotating with the rotation of the input shaft and positioned in the axial direction of the transmission.

A request control apparatus and a request control method are configured such that when an A type request that is an overtaking acceptable request allowed to overtake and to be overtaken among the other requests is turned to a retry matter on a pipeline, a request-order control unit performs an information renewal such that the A type request is rearranged to a place immediately preceding a B type request that is an overtaking inhibited request inhibited to overtake or to be overtaken among the other requests, and a request fetching unit fetches requests from ports by using the information renewed by the request-order control unit. Moreover, the request-order control unit is configured to perform request order control per request source.

Disclosed is a process for production of succinic acid, which comprises the step of reacting a bacterium which has been modified so as to increase the expression of a sucE1 gene or a product produced by any treatment of the bacterium with an organic raw material in a reaction solution containing a carbonate ion, a bicarbonate ion or carbon dioxide gas to thereby yield the desired succinic acid.

Provided is an ultra-low profile pneumatic radial tire for SUV or the like having an aspect ration of 55% or less and a tire outer diameter of 720 mm or more, which has improved load durability while managing a weight reduction without deteriorating driveability. A carcass layer (4) thereof is configured as a single ply, and both ends thereof are folded back around left and right bead cores (7) so as to wrap bead fillers (8). A folded-back portion (4t) is wrapped on the inner side of an end of a belt layer (5) in a range not greater than 10% of the maximum width of the belt layer (5). The hardness of the bead fillers is 65 to 80 in terms of JIS durometer A hardness, and a height hb of the bead fillers (8) from a bead base is brought to 10 to 20% of the height H of a tire cross-section.
摘要:
A cache-memory control apparatus controls a level-1 (L1) cache and a level-2 (L2) cache having a cache line divided into a plurality of sub-lines for storing data from the L1 cache. The cache-memory control apparatus includes a control-flag adding unit, an L1 cache control unit, and an L2 cache control unit. The control-flag adding unit provides an SP flag to each of the sub-lines. The L1-cache control unit acquires an access virtual address, and, when there is no data at the access virtual address, outputs an L2 cache-access address to the L2-cache control unit. The L2-cache control unit switches the SP flag based on a virtual page number in an L1 index and a physical page number in an L2 index. Based on the SP flag, corresponding one of the sub-lines is written back to the L1 cache.

A clutch control device is provided for a clutch to connect and disconnect the transmission of a rotational drive force from a power source to a drive wheel in a vehicle. A clutch control unit is configured to control a control amount for said clutch. A drive wheel rotation start detector is configured to detect a start of rotation of said drive wheel. A control correction amount calculator is configured to calculate a control correction amount of said clutch based on a difference between the clutch control amount detected at the start of rotation of said drive wheel and a predetermined reference value. The clutch control unit is further configured to apply said control correction amount to the control amount for said clutch to control said clutch.
