摘要:
A transfer belt for use on an electrostatographic duplicator. The belt has a body defining an image transfer surface. The body is made up of a rubber composition including a combination of epichlorohydrin-ethyleneoxide copolymer and hydrogenated nitrile rubber, to which a metallic salt of an unsaturated carboxylic acid and an organic peroxide are added.
摘要:
A belt for conveying articles, which belt has a body having a surface against which articles are placed to be frictionally held and thereby conveyed as the belt is advanced in operation. The belt body surface is defined by rubber and a porous filler in the rubber. The porous filler is present in the rubber in an amount of at least 5 parts by weight of porous filler per 100 parts by weight of rubber.
摘要:
A toothed belt having a body with a length, laterally spaced sides, an inside and an outside, and defining a plurality of teeth spaced in a lengthwise direction on one of the inside and the outside of the body. The body is defined at least in part by a rubber composition made up of at least an ethylene propylene diene monomer (EPDM) and a diene rubber. A cloth layer is provided on the teeth on the one of the inside and the outside of the body. The cloth layer is treated with a resorcin-formalin-latex solution.
摘要:
A drive system having a belt with a length and a plurality of teeth spaced regularly along the length of the belt and a first pulley having a plurality of grooves for receiving the belt teeth with the belt and first pulley in operative relationship. The single pitch difference between the belt teeth and the grooves in the first pulley is between -0.04 mm and 0 mm.
摘要:
There is provided a metal detection device capable of effectively detecting a metal mixed in food or the like by generating AC magnetic field simultaneously tuned to respective frequencies by a single transmission coil in response to frequency components of different frequencies without switching an element by a switch or the like. Constituent elements constituting magnetic field generation means (2) are connected so that a transmission coil L1 and a capacitor C1 resonate in the first frequency F1. Moreover, constituent elements are connected so that the transmission coil L1 and a capacitor C2 resonate in the second frequency F2. Furthermore, constituent elements function so as to effectively separate the capacitor C1 and capacitor C2 so that they do not interfere at least in the same frequency.
