摘要： A valve gear for an internal combustion engine capable of promptly switching the position of a piston in a rocker arm to thereby change the engine operating condition with a satisfactory response, even in a low rotation region in which an adequate amount of oil discharged from an oil pump cannot be expected. Depending on positions of pistons slidably fitted in low-speed and high-speed cylinder portions provided in an intake driven rocker arm, a low-speed or high-speed drive rocker arm is selectively operated to press a corresponding one of the pistons. The piston in the low-speed cylinder portion switched in a low rotation region is made smaller in diameter than the piston in the high-speed cylinder portion, to be enabled to be promptly switched.

摘要： A plurality of oil passages are formed in a shaft body of a rocker shaft, which partially constitutes a valve drive system of an internal combustion engine. A bolt hole is formed in the shaft body in such a manner as to substantially perpendicularly intersect the axis of the shaft body. A bush is fitted into the bolt hole in such a manner as to prevent the bolt hole from establishing communication between the plurality of oil passages. A bolt is fastened through the bush to thereby fix the rocker shaft on a cylinder head. This structure improves the support rigidity of the rocker shaft and the dynamic characteristics of the valve drive system, and reduces the number of components and the number of working man-hours.

摘要： An electrophotographic recording apparatus including a light-sensitive drum for carrying toner images developed thereon, and a transfer unit arranged at a prescribed distance from the light-sensitive drum for transferring the toner images from a light-sensitive drum to the image recording paper. The transfer unit has a charging wire electrode for electrically charging the paper and a generally inverted U-shaped housing having spaced sidewalls with respective bottom edges. A separator is provided for separating the paper from the light-sensitive drum as the paper travels along a conveying path and comprises a paper separating plate extending from the downstream one of the bottom edges of the housing of the transfer unit in the downstream direction of the travel of the paper along the conveying path side thereof, with and the housing of the transfer unit is grounded. The paper separating plate has a distal end having a saw tooth shape along the length thereof, as measured transversely to the conveying path.

摘要： There is provided a valve system for an internal combustion engine, in which a rocker shaft required to have a higher stiffness has a larger diameter. A rocker shaft on an intake side is formed to have a larger diameter than that of a rocker shaft on an exhaust side, and therefore, it is possible to ensure such stiffness as to compensate for an excess in weight and to improve valve operating characteristics of a valve system.

摘要： A toner quantity detecting system has a toner quantity detector (4c) and is capable of accurately detecting the decrease of the quantity of toner contained in the toner container of the developing unit of an image recording apparatus to an upper threshold quantity and to a lower threshold quantity regardless of the inherent output characteristic of the toner quantity detector (4c) and determining a prewarning voltage (E.sub.nep) representing the upper threshold quantity and a warning voltage (E.sub.emp) representing the lower threshold quantity so that the difference between the prewarning voltage (E.sub.nep) and the warning voltage (E.sub.emp) is sufficiently large. The prewarning voltage (E.sub.nep) and the warning voltage (E.sub.emp) are determined on the basis of the inherent output characteristic of the toner quantity detector (4c). The output voltage (E.sub.s) of the toner quantity detector (4c) is compared with the prewarning voltage (E.sub.nep) and the warning voltage (E.sub.emp) to provide a prewarning signal (NAL) upon the reduction of the quantity of the toner to the upper threshold quantity and to provide a warning signal (EAL) upon the reduction of the quantity of the toner to the lower threshold quantity.
