摘要:
An image is recorded on an elongate image recording medium by feeding the image recording medium in an auxiliary scanning direction from a loading unit and applying a light beam to the image recording medium in a main scanning direction transverse to the auxiliary scanning direction. A loose loop is formed out of the image recording medium between the loading unit and an image scanning recording unit. Guide plates are angularly displaced to allow the image recording medium to hang by gravity with the image recording medium with the image recorded thereon having a free distal end. The hanging image recording medium is moved back toward the image scanning recording unit after the image has been recorded. The guide plates are displaced back to deliver the image recording medium to a next process.
摘要:
A process for producing a cycloolefin addition polymer in which one or more cycloolefin monomers can be (co)polymerized by addition polymerization with a small palladium catalyst amount to produce a cycloolefin addition (co)polymer while attaining high catalytic activity. The process for cycloolefin addition polymer production is characterized by addition-polymerizing one or more cycloolefin monomers comprising a cycloolefin compound represented by a specific formula in the presence of a multi-component catalyst comprising (a) a palladium compound and (b) a specific phosphorus compound.

摘要:
A snowmobile includes a quadrilateral linkage system formed between a vehicle body frame, a front torque arm assembly, a rear torque arm assembly, and an extendable member. The four-node linkage is coupled with at least one slide rail to provide for the vertical distance between the vehicle body frame and the at least one slide rail to vary. The nodes of the four-node linkage are configured to generally define a quadrilateral shape in at least fully contracted and fully expanded configurations.
