摘要:
A fixing roll for electrophotography having a surface layer of a cured room-temperature-vulcanizing silicone rubber composition comprising a mixture consisting of two diorganopolysiloxanes, one of which is terminated at the chain ends with silanol groups and has a relatively high viscosity, and the other of which is terminated at the chain ends with trialkyl silyl groups and has a relatively low viscosity, an alkoxysilane or a partial hydrolysis-condensate thereof as the crosslinking agent, a metal salt of an organic acid as the reaction catalyst, and three kinds of inorganic fillers, namely, calcium carbonate, iron oxide, and titanium dioxide, and containing substantially no siliceous fillers. The fixing rolls have excellent properties including, in particular, the ability to provide a long copy-life to electrophotographic copying machines.

摘要:
A CPU provides a fluorescent light detecting head with an irradiation instruction, in response to which the fluorescent light detecting head irradiates an ultraviolet ray for detection on an ultraviolet curing resin material to be examined. The CPU then acquires from the fluorescent light detecting head an intensity of a fluorescent light emitted from a photo polymerization initiator included in the ultraviolet curing resin material when receiving the ultraviolet ray for detection. The CPU retrieves a predetermined number of past data of the intensity of the fluorescent light from a storage unit and performs a (moving) average calculation processing to calculate the intensity of the fluorescent light at the current time. The CPU performs an estimation processing of a state of the ultraviolet curing resin material based on the calculated intensity of the fluorescent light.

Two mirrors (15) and (16) making an angle of 90 degrees are formed on a front face of a mirror member (17). An optical fiber for input (12) and an optical fiber for output (13) are held in a fiber array (14) with a predetermined interval, and an emission lens (23) and an injection lens (24) are provided on a front face of the fiber array (14) in a way that they are opposed to end faces of the optical fiber for input (12) and the optical fiber for output (13) respectively. According to the variable optical attenuator, when the mirror member (17) is straightly moved by an actuator (18), light attenuation can be varied thereby.
