Title: Apparatus for screening broken bag from can and bottle
Inventor: KOMODA MOTOAKI
IPC: B07B4/06
Filed: 1995-01-30
Abstract: PURPOSE: To separate automatically broken bags from cans and bottles. CONSTITUTION: The inside of a porous rotary cylinder 2 is divided into a negative pressure chamber 4 and a positive pressure chamber 5 by a fixed partition wall 3. Waste W of a mixture of bags (a) broken by a bag breaker and cans and bottles (b) is supplied to the negative pressure chamber 4 side of the cylinder 2. The broken bags (a) are attracted by the suction force of the negative pressure chamber 4 to be separated from cans and bottles. In this way, by supplying waste of a mixture of broken bags, cans and bottles to the negative pressure chamber of the rotary cylinder, the broken bags attracted by the suction force of the negative pressure chamber are transferred with the cylinder, while cans and bottles are not attracted and fall down so that the broken bags can be separated surely from cans and bottles.

Title: Safety device of dump truck
Inventor: YAMAGUCHI KOUZOU
IPC: B60P1/04
Filed: 1984-02-25
Abstract: PURPOSE:To inhibit the descending of a rear deck through erroneous operations during maintenance by not only pushing down a control lever but also controlling a switch set on the outside panel of a cab when lowering the rear deck of a dump car. CONSTITUTION:A descent switch 12 is set on the outside panel of a cab, and an arrangement is made so that the electromagnetic open/close valve, which is inserted in and connected to the high-pressure circuit of a hoist cylinder 14, can not be opened without controlling this switch. And the descent switch 12 can be made smaller in size as compared to the existing ones and it can be easily attached to any car. Moreover, the descent switch 12 can be controlled seeing under a rear deck 18, so the safety can be secured when the rear deck goes down. Even if a worker should go under the tilted rear deck and accidentally pull the remote control cable, the hydraulic circuit of the hoist cylinder could not be switched; thus the safety is assured all the time.

Abstract: PURPOSE: To separate acrylic fibers well in the calcining step and to improve the coherency in the carbonization step, by applying a water-dispersible silicon oiling agent to fivers, obtained through spinning, drawing, rinsing and drying steps, and by carbonizing the fibers as a precursor.  
     CONSTITUTION: Acrylic fibers obtained by drawing fibers spun from an acrylonitrile polymer solution, by rinsing with water, and drying the fibers, are oiled with a water-dispersible silicon agent to give an oil pickup of 3W25 wt.% o.w.f. and a water pickup of 3W25 wt.% o.w.f., and used as a precursor. The fibers thus obtained are readily windable, will neither form collapsed corns readily, nor cause abnormal fluffing or widening by static build-up although with suitable separation in the calcining step. Cohesion or bonding in the calcining can be effectively prevented with high continuous calcining operation efficiency give high modulus and tensile corbon fibers.

Abstract: PROBLEM TO BE SOLVED: To prevent increase in frictional torque by reducing the axial height of inner rings of outer rings of a side, to which a preload is to be applied, smaller than the axial height of the inner rings or the outer rings, to which the preload is not applied. SOLUTION: In each upper and lower ball bearings 24, 27, an axial height (thickness) (h) of inner rings 28, 29 to which a preload is to be applied, is formed smaller than an axial height H of outer rings 30, 31, to which the preload is not applied. Consequently, in the ball bearings 24, 27 ends of the outer rings 30, 31 are projected from ends of the inner rings 28, 29 by a predetermined length (d) due to the difference between the height H, (h) of the outer rings 30, 31 and the inner rings 28, 29, and this length (d) is formed larger than the quantity of play between the inner and the outer rings 28, 29, 30, 31 and a ball 17.  Consequently, the outer rings 30, 31 are provided without interposing a spacer so as to form a clearance twice a constant length (d) between each end surfaces of the inner rings 28, 29, and fitting failure is eliminated so as to prevent the increase in the frictional torque.
