Title: Image synthesizing device of electronic copying machine
Inventor: HORIUCHI TATSUMI
IPC: G03G15/043
Filed: 1985-01-29
Abstract: PURPOSE:To prevent a synthesized copy from being overprinted by forming a slight blank part between both a trimming and a masking area when the synthesized copy is taken. CONSTITUTION:The 1st original is placed on an original platen, and a ten-key 6 and function keys 7 are operated to input coordinate data on the trimming area 11 to a control circuit 21. Similarly, coordinate data on the masking area 12 of the 2nd original is also inputted. When the composite copy of both areas 11 and 12 is taken, the trimming area 11 is copied firstly and then the masking area 12 is overprinted, but the control circuit 21 controls the width of electrostatic discharging so that a slight blank part is formed between both areas 11 and 12. Consequently, the formation of the overprinting part 13 of both images is prevented and an excellent image is formed.

Title: Methacrylic resin for optical information recording medium
Inventor: TAYAMA SUEHIRO
IPC: G11B7/24047
Filed: 1991-02-07
Abstract: PURPOSE:To enhance the heat resistance, flowability and productivity of the resin for a substrate without deteriorating the optical characteristic by using a methacrylic resin consisting of methyl methacrylate and isobornyl acrylate. CONSTITUTION:This resin consists of 80-99.5wt.% of a methyl methacrylate unit (A) and 20-0.5wt.% of an isobornyl acrylate unit (B). When the unit A is controlled to >99.5%, the mol.wt. has to be lowered to maintain its flowability, and hence the mechanical strength is reduced. Meanwhile, when the unit B exceeds 20%, the mechanical strength is remarkably lowered. Besides, the melt flow rate and heat-deflection temp. of the resin are preferably specified.

Filed: 1990-01-26
Abstract: PURPOSE:To ensure graft polymn. by setting the discharge time of a stage for graft polymerizing N, N'-dimethyl acrylamide on a lens surface for 2 seconds to 10 minutes. CONSTITUTION:Radicals are generated on the surface of a molding by treating the molding of the contact lens.

Further, the peroxides are decomposed to form an initiator when this molding is immersed in a hydrophilic monomer soln. and the temp. is raised. The polymn. starts and the hydrophilic monomer is grafted. The density and quantity of the formed radicals are dependent upon the discharge time. Namely, the molding formed with 2 seconds to 10 minutes of the discharge time is stuck with the specific graft quantity or above of the N, N'-dimethyl acrylamide after the surface treatment. The effect of the surface reforming is permanently enhanced in this way.
