摘要:
A chain guide structure having, in combination, a chain cover and a chain guide member which can easily and securely be placed on the chain cover for temporary assembling, and capable of improving the efficiency of the assembling work. A chain guide structure for guiding a chain wound round a driving sprocket supported on the sidewall of a crankcase and covered with a cover attached to the sidewall includes an elastic chain guide member having a substantially semicircular shape opening toward the rear and supported on the inner surface of the cover so as to extend along the chain. At least two ribs are formed on the inner surface of the cover so as to hold the chain guide member by elastically deforming the chain guide member so that the width of the open end of the chain guide member is changed.

When controlling each operational process in a molding cycle by variably controlling the number of revolutions of a drive motor 3 in a hydraulic pump 2, a hydraulic pump 2 where at least multiple fixed discharge flow rate Qo and Qs can be set is used as the hydraulic pump 2. At the same time, the fixed discharge flow rates Qo . . . are set corresponding to operational processes based upon predetermined conditions in advance, respectively, and the hydraulic pump 2 is switched to the fixed discharge flow rates Qo . . . by corresponding to each operational process at the time of molding. At the same time, each operational process is controlled by variably controlling the number of revolutions of the drive motor 3.

The inside of a crankcase for a four-cycle engine is divided by a bulkhead into a crank chamber and a transmission chamber. A crankshaft and a balancer shaft for suppressing engine vibrations by rotating in accompaniment with rotations of the crankshaft are rotatably attached within the crankshaft, and the balancer shaft is driven by the crankshaft via a gear set housed within the crank chamber. Meshing parts of a gear set can be sufficiently lubricated by oil mist without a special lubricating structure being required. Furthermore, the engine can be decreased in size without forming a sealed space for lubricating the gear set.

A bonding apparatus according to the present invention relates to a sewing machine (28) which on stitching a connecting flap and a flap to be connected (hereafter referred to as only ‘connected flap’) of one unit, one set of two sheets for a corrugated cardboard box, ensures the folding of the connecting flap and the connected flap, inhibits the blind movement of the position, rectangular in section, of the sheets for the corrugated cardboard box when thread-stitching them, solves the load burdened on a looper mechanism, and provides an appropriate thread-stitching work. The sewing machine (28) comprises a sewing-machine needle mechanism (28b) provided with a sewing-machine needle (28a) and the looper mechanism (28d) having a needle plate (28c). This sewing machine (28) arranges the needle plate (28c) of the looper mechanism (28d) inside the connecting flap (12a) and the sewing-machine needle mechanism (28b) outside the connected flap (12b) and holds the position, rectangular in section, of the both sheets (W1. W2) of the corrugated cardboard box and intermittently moves them in parallel to the first folding line (10) and synchronizes the sewing-machine needle (28a) with the intermittent movement to reciprocally move it horizontally from the outside to the inside of the threading portion (S) so as to stitch the threading portion with threads.

摘要:
A lubrication system for an engine includes an oil discharge port in a lower section of a crankcase. A crankshaft, with a crank web attached thereto, rotates in a rotation direction within the crankcase. A first distance is formed between the crank web and a first inner surface of the crankcase, downstream of the oil discharge port. A second distance is formed between the crank web and a second inner surface of the crankcase, upstream of the oil discharge port. The first distance is less than the second distance. Also, the oil discharge port is defined in part by a back edge, which is wedge shaped and points in a direction opposite the rotation direction of the crankshaft. The back edge scoops oil from the crank web and into the oil discharge port.
