PURPOSE:To enable to arbitrarily change the driving mode so as to suit to running conditions by a structure wherein a differential lock clutch is arranged between the input side and the output side of a differential gear and at the same time a change-over clutch is arranged in the part of the output side of the differential gear. CONSTITUTION:A differential gear 7 provides with a pair of output sh...

A method of reducing the lateral force variation exerted by a rotating pneumatic tire on its supporting surface, which method comprises mounting the tire on a rotatable rim, inflating the tire to a preselected pressure, urging the tire against a load roll with a preselected force, rotating the tire to determine the lateral force variation, grinding the axially outer rib of the tire on the side of ...

PURPOSE:To enable to transmit driving force in both of forward and reverse directions and to rotate driven shafts freely at a high speed, by the use of a clutch mechanism adopting all types of pawl members, rollers and sprags as clutch elements. CONSTITUTION:A pair of pawl members 10a, 10b are supported in a pivotally movable manner on a pin 10 which is formed integrally with a driving shaft. In d...

PURPOSE:To perform quickly and safely increasing and decreasing of the quantity of water supply at a complicated water supply lines by controlling the number of revolutions of a pump as well as an opening degree of a valve by comparison a pressure in the tube at the determined position of the water supply lines with the set upper and lower limit pressure.

A centrifugal separator having a rotary bowl for receiving feed which forms a pool within the bowl a skimmer movably mounted to fixed structure within the bowl for removing liquid from the pool to a discharge system with an outlet external to the bowl, and adjustment means operable from outside the bowl for adjustably moving the skimmer oppositely toward and away from the bowl axis to vary the poo...

A computer implemented process for optimizing the decarburization of a predetermined mass of molten metal by controlling the amount of coolants, the charging time of coolants, the dilution ratio of injected oxygen to inert gas, the changing time of said dilution ratio and the amount of injected gases which comprises : considering that from a standpoint of kinetic theory the reaction in AOD vessel ...

A creel (10) comprises a frame (14) mounted in a C-shaped support structure to be pivotal about its vertical central axis (17). The frame (14) defines four spaces (22) on each of three levels. In each space (22) are pivotally mounted a pair of rigidly spaced package support arms (24, 25) which are together pivotable between two operative positions offset towards each side of the space (22) so that...

A linear actuator is a hybrid in that movement of the armature is influenced by the field of permanent magnets and the field of a coil when it is energized by direct current. The coil is fixed in a ferromagnetic shell and a pair of permanent magnets are fixed in the shell axially of the coil. The armature has a reduced diameter tip or end which is influenced by the magnets when the coil is deenerg...
