Filed: 1982-08-31
Abstract: PURPOSE:To carry out continuous spinning with high drying energy efficiency reducing the adhesion of dried scum to an extremely low level, by providing a zone wherein the yarn in transported without supply of the scouring liquid on the roll, between the scouring zone and the drying zone. CONSTITUTION:The yarn passed through the spinning zone is introduced along the direction of the arrow 1 into the roll treatment zone composed of the roll 2a and the roll 2b. The roll 2a is continuously supplied with the scouring liquid 5 from the scouring liquid feeder 4. The scouring liquid 5 is attached to the yarn when the yarn passes through the scouring zone 6. The yarn coated with the scouring liquid is transferred through the idling zone 7 wherein no scouring liquid is supplied the roll 2a. The excess scouring liquid attached to the yarn in removed in this zone. The yarn is then dried in the drying zone 8, delivered from the roll treatment zone, and wound by the winder to obtain a filament yarn without troubles.

Abstract: PURPOSE:To increase the dynamic range, improve the sensitivity, and reduce the unit picture element size of a charge transfer element by performing impurity diffusion for forming transfer channels by making ion implantation obliquely and nearly perpendicular to a semiconductor substrate into two or more kinds of plain faces of such three kinds of flat face sections as plain faces between U-shaped grooves, side wall faces of the grooves, and bottom faces of the grooves. CONSTITUTION:U-shaped grooves are formed by trench-etching the first oxide film 12 and a semiconductor substrate underlying the film 12 and impurities for forming transfer channel, such as phosphor, arsenic, etc., are diffused by ion implantation. As a result, N-type diffusion layers 14 for transfer channel are formed on right side wall faces of the grooves. The incident angle of the ion beam used for the implantation is set at about 45 deg. from the surface of the substrate. The second ion implantation is made at 45 deg. in the upper right direction and N-type diffusion layers 15 are formed on the left side wall faces of the grooves. Then N-type diffusion layers 17 and 18 are formed by ion-implanting the impurities for forming transfer channel after areas where no transfer channel is formed are covered with a mask material 16, such as resist, etc. Therefore, transferable charges can be ensured to the same extent even when the transfer channel width per unit picture element area is reduced.

Filed: 1995-05-25
Abstract: PURPOSE: To reduce the penetration of dust or waste refuse into a recording part by providing an electrostatic attraction sheet effectively removing the dust or waste refuse bonded to a recording medium. CONSTITUTION: Recording paper is drawn out of roll recording paper 13 to pass under a guide shaft 17 and inserted in the gap between a platen 14 and a thermal head 15 to be guided to a recording part.

When recording is performed, the recording paper is successively drawn out and the peripheral surface of the roll recording paper 13 is rotated. Therefore, static electricity is generated by the friction with the roll recording paper 13 and the dust or waste refuse bonded to the surface of the recording paper is attracted to the electrostatic attraction sheet 16 and, therefore, a large quantity of dust or waste refuse is not bonded to the recording paper guided to the recording part.
