Abstract: The objects of this invention are to set a predetermined height position for the portion of parison or preform that is the first to come in contact with body molding planes of a split mold and to prevent air from being trapped between in-mold labels and the container which is blow molded from the parison or the preform. In-mold labels are fixed to the entire outer surface of body of main container. An annular thinnest wall portion is formed in the wall of the body so that the thinnest wall portion is the first to come in contact with the body molding planes of a split mold. Under this construction, no bulge of air is formed between the body and the in-mold labels fixed to the entire surface of the body.

Abstract: In case a burden is discharged from a vessel (3), the vessel (3) is raised obliquely backward with respect to a vehicle body (2) by a hoist cylinder (10). However, when discharging work is stopped on the way, the vessel (3) is temporarily lowered to a position at which this sits on the vehicle body (2). When the vessel (3) lowers, a weight of the burden left loaded thereon acts on the hoist cylinder (10) as a load in addition to the weight of the vessel (3). A controller (35) determines whether the vessel (3) lowers in a burden loading state based on various detection signals. When the vessel (3) lowers in the burden loading state, switching of directional control valves (20) and (21) is controlled so as to decrease a contracting speed of the hoist cylinder (10), thereby prevent the vessel (3) from colliding against the vehicle body (2).

Abstract: A control valve device comprises two direction control valves. The direction control valve includes an expansion side variable throttle portion and a contraction side variable throttle portion. The direction control valve includes an expansion side variable throttle portion and a contraction side variable throttle portion. When a hoist cylinder is telescopically operated to raise or lower a vessel, as the hoist cylinder approaches a stop position, a controller determines that the hoist cylinder gets close to the stop position. Based upon this determination, the controller variably adjusts a flow passage area of the direction control valve using the variable throttle portions or variably adjusts a flow passage area of the direction control valve using the variable throttle portions in such a manner as to slow down or speed up the telescopic speed of the hoist cylinder corresponding to the weight in the side of vessel.

Abstract: A load measuring device for a construction machine includes a processing unit for acquiring signals indicative of cylinder pressure of front and rear suspension cylinders via pressure sensors and computing a weight value of a load put on a dump body of the construction machine. When the construction machine is traveling on a curvilinear route, the construction machine makes the output of the weight value ineffective. In particular, when the differential speed value between the rear wheels, received from a speed difference detector, is below a preset value, the arithmetic unit outputs a loading weight W computed by the processing unit, as final loading weight, and so that when the differential speed exceeds the preset value, the arithmetic unit makes ineffective the computed loading weight W as the final loading weight output.

Abstract: When the drive of a lubricant pump (46) is stopped to prevent the lubricant pump (46) from assuming an idling state, a determination is made as to whether or not a temperature difference (?T) between the temperature (T) of a lubricant oil detected earlier by a temperature sensor (51) and a warning temperature (Toh) is equal to or lower than a predetermined threshold value (?). When the temperature difference (?T) is within the threshold value (?), an “overheat” warning is issued to an operator of a dump truck (1). In consequence, even in a case where a temperature sensor (51) is provided on the output side of the lubricant pump (46) by being located on an outer side of a wheel mounting case (19), planetary gear reduction mechanisms (23), (31) inside the wheel mounting case (19) can be prevented from overheating by warning the operator of the vehicle.

Abstract: A bag container including a synthetic-resin container body shaped by using a mold and including a spout-forming portion and a filling inlet portion that project outward therefrom. Contents are first filled through the filling inlet portion, and then fusion-bond sealing is applied to the filling inlet portion. The filling inlet portion has, at its sealing base portion, a square cross-sectional shape. A tip-end-side cross-section-changing portion and a cylindrical portion are provided on the tip-end side with respect to the sealing base portion. Four triangular panels each isosceles triangle shaped are connectedly provided on the side of the container body with respect to the sealing base portion along a circumferential direction of the filling inlet portion, a base of each isosceles triangle formed of one of sides of the square cross-sectional shape.

Abstract: A traveling speed reduction gear lubricating oil cooling device has a temperature sensor for detecting the temperature of lubricating oil to be installed outside a wheel mounting sleeve without running the risk of damage to a lubricating oil pump in a cold work environment. A startup operation reference speed lower than a reference speed for normal operation is set so as to ensure that air intake does not occur. A startup operation comparison device compares the speed detected by a speed sensor with the startup operation reference speed. If the detected speed is lower than the startup operation reference speed, a drive motor for the lubricating oil pump is engaged in operation at a speed lower than a normal operation speed. If the detected speed is higher than the startup operation reference speed, the drive motor for the lubricating oil pump is turned off.

Abstract: A bag container includes a synthetic-resin container body shaped by using a mold and including a body portion including a bottom portion and a spout-forming portion. A spout is formed by tearing an easy-to-tear portion of the spout-forming portion and removing a to-be-torn-off portion. The spout-forming portion is provided projecting upward, perpendicular to a placing surface formed by the bottom portion, from the body portion. An opening tab piece including an engagement hole with which the ball of a finger is to engage is provided projecting on one side of the spout-forming portion. The engagement hole has a shape that guides the finger such that, when the easy-to-tear portion is to be torn, the ball of the finger engages with a circumferential edge portion of the engagement hole from the inner side thereof while being oriented toward the circumferential direction centering about an end of the easy-to-tear portion.

Abstract: A thermal effect from a bottom cutoff portion of parison is dispersed and reduced by forming at least three pinch-off lines in an outer surface of a bottom and laying out these pinch-off lines radially from a center of the bottom of a bottle-like direct blow molded product made of a synthetic resin, which prevents a deeply dented portion from developing in an inner bottom surface. In the case of a square body, four pinch-off lines are disposed in the shape of a cross and are positioned along diagonal lines on the bottom surface and one of the diagonal lines is located on the parting line. Each outermost end of the pinch-off line is placed near bottom foot where parison walls are locally drawn and molded, which reduces the drawing rate at the foot to prevent the walls from getting extremely thin.
