摘要:
A downward component force of a tensile force exerted on a timing belt at a belt coupling part and the weight of a carriage act upon a first sliding surface of a first guide member and a second sliding surface of a second guide member via a first sliding protrusion and second sliding protrusions. Since the center of gravity of the carriage is located between the first sliding protrusion and the second sliding protrusions, the carriage can be stably supported by the first and second guide members while the carriage remains stationary or moves at a constant speed in a main scanning direction.

A fuel supply system attached to the gasoline engine includes a first tank storing a mixture of gasoline and ethanol, a second tank storing water, a microbubble generator connected to the first and second tanks, and a fuel injection valve connected to the microbubble generator. The mixture and the water are mixed in an environment where microbubbles generated by operation of the microbubble generator are supplied. The mixed fuel thus prepared is injected, via the fuel injection valve, into a supply pipe connected to a cylinder block which is included in the gasoline engine. The mixed fuel is then mixed with the air flowing through the supply pipe to be supplied into a combustion chamber. The resulting configuration lowers the combustion temperature in the gasoline engine so as to reduce the amount of NOx contained in exhaust gas.

An image-recording device including a carriage, a recording head, a guide rail, a flexible flat cable, a flexible ink supply tubes, and a top cover. The recording head is provided at the carriage. The guide rail extends in a widthwise direction of a recording medium fed in a feeding direction perpendicular to the widthwise direction. The flat cable has a broad surface extending in a horizontal direction and bent into U-shape so that an upper region of the flat cable faces the top cover whereas a lower region of the flat cable faces the base. The carriage is reciprocally movable in the widthwise direction. The flat cable is oriented upward from the carriage at a prescribed angle with respect to a horizontal plane and extends in the widthwise direction, so that at least the U-shaped bent portion of the flat cable is in continuous contact with the top cover.

An exhaust apparatus for a vehicle includes a spark arrester having a tubular spark arrester body assembled on a rear portion of a muffler connected to an exhaust pipe. A tail pipe is inserted in the spark arrester body and is mounted on the spark arrester such that exhaust gas flowing through the muffler is discharged into the atmospheric air from the tail pipe through the spark arrester, to carry out, expansion and contraction of exhaust gas in the spark arrester occurs to augment the sound reduction performance. An annular partition plate cooperates with an inner face of a spark arrester body to form a throttle path therebetween that is securely mounted on a tail pipe wherein a plurality of expansion chambers that communicate with each other through the throttle path are formed between the tail pipe and the spark arrester body with the annular partition plate disposed therebetween.

A transporting apparatus includes a base unit made of resin, a tray configured to support a sheet, a transporting section supported by an upper portion of the base unit and configured to transport the sheet, and a feeding section supported by a lower portion of the base unit and including a feeding roller configured to contact an upper surface of the sheet supported by the tray and to feed the sheet toward the transporting section. The base unit is integrally formed with an inner-side guide which defines an inner side of a curved path which is configured to guide the sheet fed by the feeding section to the transport section.

An internal combustion engine includes a crankshaft, a variable flow rate oil pump apparatus including oil pumps having a drive shaft thereof operatively connected with the crankshaft, and a rod-shaped oil passage switching valve operatively connected with the oil pumps. The oil passage switching valve and the drive shaft of the oil pumps are arranged such that axial directions thereof are parallel to an axial direction of the crankshaft. Also, the oil pumps and the oil passage switching valve are disposed so as to overlap each other in the axial direction of the crankshaft. With such configuration of the engine, the effect on various components around the pump can be reduced, while downsizing the oil pump and the engine.
