Title: Production of optical disc
Inventor: IKENO SHINOBU
IPC: G11B7/2533
Filed: 1984-06-25
Abstract: PURPOSE:To obtain a disc suitable for high-density information recording, by molding the body of an optical disc from a resin containing an acrylate ester and p-methylstyrene as a comonomer and crosslinking it by irradiation. CONSTITUTION:The body of an optical disc is molded by using the following resin and this molding is crosslinked by irradiation. Said resin is a copolymer prepared by copolymerizing 20-80wt% acrylate ester with 10-70wt% p-methylstyrene and/or isomers thereof and 0-50wt% vinyl monomer copolymerizable therewith. When 0.1-10wt%, based on the copolymer, crosslinking agent is mixed therewith, the crosslinking efficiency increases still higher, which makes it possible to perform its crosslinking by irradiation at smaller dose.

Abstract: PURPOSE:To reduce sludge-treating cost, by a method wherein an addition quantity A of an organic high polymeric flocculant with which the thickness of a dehydrated cake attains a maximum value is calculated, and the flocculant is added to a sludged in an amount equal to the addition quantity A multiplied by a constant of 0.7-1.5. CONSTITUTION:The addition quantity A of the flocculant corresponding to a maximum of the thickness of the dehydrated cake in the relationship between the quantity of the flocculant added and the thickness of the dehydrated cake is determined, and the addition quantity A is mulitplied by a constant of 0.7-1.5 to obtain a set point of addition quantity. The flocculant is added to the sludge in an amount equal to the set point to form flocs, which are coagulated, followed by dehydrating by a belt press type dehydrator. The thickness of the dehydrated cake is determined by removing end parts in the width direction of the dehydrated cake to leave a substantially uniform part and measuring the thickness of the uniform part.

Title: Device for forming gradation image by heat-sensitive printer
Inventor: YOSHIZAKI OSAMU
IPC: B41J2/36
Filed: 1980-09-25
Abstract: PURPOSE:To obtain gradation images having picture elements each uniform in image thickness without varying the image thickness irrespective of the direction of scanning, by a device wherein a recording time for each picture element is divided into equal intervals and power is fed for a period of time required for providing a given thickness throughout the recording time for each picture element. CONSTITUTION:A recording time T for each picture element is divided into intervals of time t and power is fed for a time period of t0=T0/n (T0=feeding time during the time T for forming a image) every thus divided time t. A thermal head is fed for each feeding time t0 which is uniformly distributed throughout the recording time T. By so doing, the amount of heat moving from a heat emitting material to a base is reduced comparing to the centralized feeding mode and a rise in temperature of the base is restricted within a range in which there occurs no trouble for a practical use. Also, a change in temperature for the recording time T becomes smaller in the divided feeding mode, so that a thickness grade is not produced in each picture element.
