Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To perform optimum shading correction corresponding to conditions at the time of read by selecting a correction data read mode corresponding to the read speed of original images. SOLUTION: The high speed/low speed of a read mode are judged by a transmission resolution set by input from an operation part 43 by a user.

Title: Method for producing anti-corrosive type pc board
Inventor: SUMINO MASAHIRO
IPC: E04C2/04
Filed: 1993-12-28
Abstract: PURPOSE:To provide a PC board with an excellent anti-corrosion function as well as salt- and gas-barrier properties within the time conventionally required for its production by a method wherein a coating film having an anti- corrosion function is formed on the surface of the PC board and the PC board is produced by a mere addition of plaster work to apply resin mortar, etc., using the existing production equipment. CONSTITUTION:PC mortar is first kneaded and after being placed in a formwork is vibrated for compaction. After being allowed to stand for about 2-3 hours at room temperature, the mortar is subjected to vapor curing for about 6-8 hours at a temperature of about 35-40 deg.C. The surface of the mortar deprived of a laitance layer is coated with a resin mortar. The coating operation is performed within 8-24 hours after the mortar placement. The resin mortar contains a hydrophilic epoxy resin and quartz sand as fine aggregate in a weight ratio of 1 :: 1-2 and the resin mortar is laid on the surface of the PC board with a metal trowel, etc., to a thickness of about 1-3mm. This method does not hinder the hydration of the cement, even if the resin is applied when water remains in the PC board and the hydration is proceeding.

IPC: G03G15/16
Filed: 1994-12-29
Abstract: PURPOSE: To prevent omission in a toner image even when transferring the toner image to a thick transfer material.

Abstract: PURPOSE:To smoothen the surface of a medium by forming two or more magnetic layers consisting essentially of ferromagnetic metal particles and a binder on a nonmagnetic supporting body in such a manner that the uppermost magnetic layer has the max. weight ratio of the binder to the ferromagnetic metal particles in a magnetic layer. CONSTITUTION:As for the binder, polyurethane resin PU and polyvinylchloride copolymers PVC are used and the weight ratio, PU to PVC is made max. in the uppermost layer. The weight ratio (a) of the binder to the ferromagnetic metal particles in the uppermost layer is preferably 15-30 pts.wt. of the binder per 100 pts.wt of the ferromagnetic metal powder. In magnetic layers except for the uppermost magnetic layer, the weight ratio (b) of the binder to the ferromagnetic metal powder is preferably 10-18 pts.wt. of the binder per 100 pts.wt. of the ferromagnetic metal powder. By specifying the weight ratios to a>b, influence of self demagnetization is decreased and the uppermost layer has higher coercive force than the other magnetic layers. Thereby, the surface of the medium can be smoothened, which improves luminance output and S/N.

Title: Laminated board for printed circuit
Inventor: UEKI MASAAKI
IPC: H01B5/14
Filed: 1993-12-08
Abstract: PURPOSE:To produce a laminated board without generating even when the resin content is increased and improve its workability by using a resin composition that is made by mixing a matrix resin and a resin filler made of a crushed cured resin with the same composition. CONSTITUTION:A conductive layer is provided on at least one side of an insulation layer. Then, a matrix resin and a resin filler that is made of a cured resin with the same composition are integrally formed, as an insulation layer, on a fiber substrate together with an essential resin composition through heating and pressurizing by using a coated, immersed and dried prepreg, thereby producing a laminated board for printed circuit with a low dielectric constant. Because the resin composition is mixed with a resin filler made of cured resin powder, its melting viscosity becomes high, and as a result, even when the resin content is increased, a resin hardly flows during a thermal press laminating process and the shift of a prepreg or mirror-finished stainless plate for wear plate hardly occurs as well.
