Abstract: A blower tube connected to a blower of an air-jet type cleaner comprises a straight tube part having one end connected to the blower; and a deflecting part, extending from the other end of the straight tube part, for receiving an airflow within the straight tube part and deflecting thus received airflow. A nozzle for jetting out the airflow deflected by the deflecting part is defined in the straight tube part and deflecting part. The deflecting part does not protrude sideways from the straight tube part. In this configuration, the blower tube can be handled as if it is a straight rod-like body, and can be inserted into a narrow space for cleaning.

Abstract: The present invention relates to a driving unit comprising a multiple-stage planetary gear type reducer used to reduce rotation speed of a hydraulic motor and output the reduced rotation speed, which is used as a driving device for a traveling apparatus. The driving unit of the present invention is so structured that a trunnion boss for rotatably supporting a planetary gear train of a final state is supported at opposite ends thereof. This structure enables the load applied to the trunnion boss to be dispersed to the both ends, and as such can allow the trannion boss to be reduced in diameter or can allow the fixed casing to be reduced in circumferential dimension. This can produce a downsized driving unit. The present invention has additional features, such as the feature that an output shaft of the hydraulic motor and an input shaft of the reducer are formed in the form of a single rotating shaft.

Abstract: A method for extracting parasitic capacitance from an integrated circuit layout includes decomposing nets in the integrated circuit layout into conductive segments along two mutually perpendicular directions. The method further includes summing capacitances between the conductive segments in a selected net and the other conductive segments in the integrated circuit layout that are aligned with the conductive segments in the selected net and multiplying the sum by a first scaling factor to obtain a first capacitance value. The method further includes summing capacitances between the conductive segments in the selected net and the other conductive segments in the integrated circuit layout that are transverse to the conductive segments in the selected net to obtain a second capacitance value. The first capacitance value and the second capacitance value are added together to obtain a total capacitance value for the selected net.

The slide mounting bar is adapted to move along an axis of a side opening of the body of the blowout preventer. A swivel is coupled to the mounting bar and to the bonnet. The swivel is adapted to enable rotation of the bonnet when the bonnet is disengaged from the body of the blowout preventer.

Abstract: A centrifugal blower comprises an impeller; and a casing, having an intake port disposed at a region opposing the air inlet portion of impeller, for accommodating the impeller. The casing is provided with a port cover constituted by rod-shaped members which are arranged in a net structure, in order to cover the intake port of casing. A trailing edge portion of the rod-shaped members is formed with a slanted surface. Due to this slanted surface, the flow of air passing through the port cover so as to flow into the air inlet portion is smoothly deflected away from the axis of rotation of impeller. As a consequence, swirls are restrained from occurring, whereby a sound-insulating effect is exhibited.

Then, an acid regenerating agent B is passed through the strongly acidic cation exchange resin to regenerate the strongly acidic cation exchange resin.

Abstract: A memory allocation scheme for object allocation in concurrent object-oriented server-side environments that combines the time efficiency of thread-local allocation schemes with the space efficiency of shared-heap allocation schemes has been developed. A pool of memory allocation spaces is maintained so that when a thread transitions to a runnable state, it is allocated a private memory space. However, when the thread transitions out of the runnable state and no longer needs its allocated memory, the space is re-allocated back to the pool for use by another runnable state thread.
