An exercise machine comprises an element for an application of a force by a user, a plurality of weights for countering the force applied on the element, which can be stacked on one another, a load regulator which in turn comprises a pulling bar, the pulling bar is able to slide in a longitudinal slot and can be associated with the weights and has a plurality of grooves along its longitudinal extension.

A bending machine has a base and a stage having a movable ram to press a metal plate on the base with a shaping process. The base has an opening corresponding to the ram to allow the ram to pass through the opening. The stage has a pivotal end mounted pivotally with a side of the base, and a detachable end detachably mounted with the other side of the base and adjacent to the opening of the base. When a shaped metal plate tightly clamps the ram, the detachable end of the stage can be detached fr...

A working machine includes a working arm, the arm in use, carrying a working implement, the arm being raisable and lowerable about a generally horizontal axis by a power operated device, a cab structure for an operator, an engine for providing power to a ground engaging drive structure to drive the machine over the ground and for operating the working arm, each of the working arm, the cab structure and the engine being mounted on a machine chassis, and the machine being characterized in that the...

A lobster banding machine having a tube feeder for feeding a tube of elastic material, a guillotine assembly to cut individual elastic bands from the tube material, jaws to grip and move the tube of elastic material, the gripping assembly having first and second arms, each arm having a finger mechanism mounted at a distal end for gripping a single elastic band.

A magnet seat is disposed on a second yoke portion and projects into respective spaces between circumferentially-adjacent pairs of second claw-shaped magnetic pole portions, and permanent magnets are disposed only near the second yoke portion so as to be held by the magnet seat so as to face an inner circumferential surface near a tip end of each of a plurality of first claw-shaped magnetic pole portions. Each of the permanent magnets is magnetically oriented in a reverse direction to an orienta...

In a rotating electric machine including a field pole unit having ten magnetic poles (P=10) and an armature having twelve teeth (Q=12), armature coils are wound around the successive teeth with phase relationships and winding polarities arranged in the order of U+/U+, U-/V+, V-/V-, W-/V+, W+/W+, W-/U+, U-/U-, U+/V-, V+/V+, W+/V-, W-/W- and W+/U-, where "U," "V" and "W" represent three phases of the individual armature coils while "+" and "-" denote winding polarities. Among all harmonic componen...

A computer natural language translation system inputs source language text and outputs target language text. The target language text is generated from the source language text using stored translation data generated from examples of source and corresponding target language texts. The stored translation data includes a plurality of translation components, each having surface data representative of the order of occurrence of language units in the component; dependency data related to the semantic...

A sewing machine includes a rotating hook, a lower shaft rotating the rotating hook in synchronization with vertical movement of the needlebar, a lower shaft gear including a helical gear and slidably mounted on the lower shaft, a hook gear including a helical gear capable of mesh engagement with the lower shaft gear and mounted on the rotating hook, a drive force transmission mechanism supporting the lower shaft gear so that the lower shaft gear is axially moveable and transmits rotation of the...

A boom control circuit for controlling hydraulic fluid fed to a boom cylinder is provided separately and independently from a travel/stick/bucket control circuit, which serves to control hydraulic fluid fed to travel motors, a stick cylinder, and a bucket cylinder. The boom control circuit includes a boom pump, an energy recovery motor disposed in a return passage through which return fluid from the boom cylinder 8bmc passes, and a boom motor generator connected to the energy recovery motor. The...

A sawing machine includes a base, a saw arm assembly pivotally connected to the base and having a L-shaped groove defined therein, a saw blade pivotally mounted to the saw arm assembly, a handle pivotally mounted to the L-shaped groove of the saw arm assembly for rotatable movement relative to the saw arm assembly, and a locking mechanism mounted to the handle for locking the handle to the saw arm assembly. Before operation, the handle is adjusted to the best angle that the user can conveniently...
