Title: Method for monitoring quantity of light of laser beam
Inventor: YAMAGUCHI AKIRA
IPC: G02B27/28
Filed: 1986-06-12
Abstract: PURPOSE:To highly accurately attain quantity of light monitoring by setting up two polarizing planes of a laser beam to 45 deg. from a plane formed by optical paths obtained before and after the passage of he laser beam through a beam splitter. CONSTITUTION:Both the angles formed by a laser beam 2 made incident upon the beam splitter 3 and the two polarizing planes of the laser beam 2 to the plane formed by a transmitted beam 2A and a reflected beam 2B divided by the beam splitter 3 are set up to about 45 deg.. Consequently, the reflectivity and transmissivity of the beam splitter 3 become equal to all polarizing components, and even if the polarizing component of a laser beam radiated from a two-plane polarizing laser 1 is varied, the laser beam is divided by the beam splitter 3 always at a constant ratio. Thus, the quantity of light of the transmitted light 2A can be highly accurately monitored by detecting the quantity of light of the reflected light 2B by a photodetector 4.

IPC: C08L51/02
Filed: 1981-09-01
Abstract: PURPOSE:To obtain a pressure-fixable good developing toner, by adding a resin obtained by copolymerizing a styrene type monomer, and/or an acrylic monomer, and a maleic acid type monomer, and a wax having a functional group, and a low mol.wt. polyethylene. CONSTITUTION:As long as a wax has >=10c,<=10,000 number average mol.wt., and a proper functional group, it is satisfactorily usable. An amount of wax used per that of syrene and/or acrylic monomer depends on the presence of other monomer, but it is not preferable that said ratio exceeds 2 times, because the properties, such as agglomeration tendency or poor fluidity, become prominent. An amount of maleic acid type monomer in the mixture of the wax and the monomers does not exceed the weight of waxes.
