摘要:
A roll type huller including a housing, a pair of hulling rolls parallelly spaced apart within the housing, a main shaft carrying one of the rolls and supported by the housing rotatably about a fixed axis, and a counter shaft carrying the other roll and supported near the free end of an arm mounted at the base by a pivot which is spaced from, and parallel with, the fixed axis, so that the counter shaft can move toward and away from the main shaft while maintaining the parallelism. The pivot is supported by the housing in a relative position opposite to the roll-carrying portion of the counter shaft. The location of the pivot may be inside the housing beneath the counter shaft or outside of the housing above the shaft or elsewhere provided the aforesaid relationship with the shaft is maintained.
摘要:
An automatic control system for a hulling machine including a fixed rotary hulling roll, a movable rotary hulling roll, means for moving the movable rotary hulling roll toward and away from the fixed rotary hulling roll to adjust the gap between the two hulling rolls and a main electric motor for driving the two hulling rolls. The system includes load detecting means for detecting the load applied to the main electric motor, and control means for connecting the load detecting means to the means for controlling the movement of the auxiliary shaft whereby the gap between the two hulling rolls can be automatically adjusted in accordance with the load applied to the main electric motor.

Provided is a sealant applicator which enables an operator to uniformly apply a given amount of sealant to a fastener in a short time regardless of the skill of the operator. The sealant applicator according to the present invention includes: an inner space defined by a substantially cylindrical inner surface that receives a fastener in an axial direction from one end; and a concave-convex portion formed in the inner surface and composed of a convex portion to be located adjacent to the fastener and a concave portion to be located apart from the fastener.

The present invention provides a metal matrix composite having stable performance without extremely weak portions and capable of assuring strength with a simple structure, the metal matrix composite being formed by hot-pressing or hot-isostatic-pressing a flat formation of reinforcing fibers 10 sandwiched between metal matrices 12 and comprising a joined end part 11 in the longitudinal direction of reinforcing fibers 10 which is joined obliquely at a joining angle of 5 to 60 degrees with respect to the longitudinal direction of reinforcing fibers or more preferably wherein a plurality of metal matrices 11 and a plurality flat formations of reinforcing fibers 10 are lapped each other to form layers of metal matrices and flat formations of reinforcing fibers so that the adjacent upper layers of flat formations of reinforcing fibers and the adjacent lower layers of flat formations of reinforcing fibers to a layer having a joined part of flat formations of reinforcing fibers are continuous and have no joined parts.
摘要:
An optically variable magnification mechanism that comprises a motor which rotates in one direction. A rotary cam is arranged so as to be rotated in one direction by the motor and has cam surfaces assigned on a periphery thereof corresponding to a plurality of magnification steps. A cam drive unit is arranged for transmitting a rotary force from the motor to the cam. An optical system is movable between positions corresponding to the magnification steps. A transmission system is arranged for transmitting a rotary force of the cam to the optical system to change the positions of the optical system sequentially.
