Title: Woven or knitted fabric similar to crepe fabric
Inventor: NEGORO ISAO
IPC: D03D15/00
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To inexpensively obtain a light and flexible crepe fabric-like woven or knitted fabric having a rough touch, a small METSUKE, and a rich volume touch, because the yarns on the surface of the fabric are bulkily opened. SOLUTION: The surface of the crepe fabric-like woven or knitted fabric is formed from doubly wound yarns 14 each produced by twisting a catching yarn 13 on a surface yarn 12 entangled on an axial yarn 11. The surface yarn 12 is fed at an overrate of >=1.5 times those of the axial yarn 11 and the catching yarn 12 to form the doubly wound yarn 14, so that the surface yarn 12 is elevated from a space between the twist mountains 17 of the catching yarn to form a RINNA 18. Thus, the surface of the doubly wound yarn 14 is unevenly covered with fine RINNAs 18 elevated from spaces between the twist mountains of the catching yarn 13 to give a rough touch to the surface of the fabric. Since the surface yarns 12 form the RINNAs 18 released from the catching actions of the catching yarns 13 to open the yarns of the surface of the fabric, the light and bulky crepe fabric-like woven or knitted fabric having the bulkily swollen surface having a rich volume touch, a small METSUKE and a rough touch is obtained.

Title: Picture memory circuit for printer device
Inventor: SHIRAKU YUTAKA
IPC: H04N1/387
Filed: 1990-07-20
Abstract: PURPOSE:To enable drawing without rotationally operating a processor by setting a data read direction vertical on a picture memory in the case of rotational printing. CONSTITUTION:In the case of rotational printing, after the second word, an adder 7 calculates the sum of the A-side value (X value) of an increment storage register 6 and a preceding address value, this sum is set to a second address register 4 as the next high-order address, and this value is applied through an address selector 5 to a picture memory 1. The picture data is selected by a selector 14 and outputted to an output (g) for each bit and when the number of count clocks (d) in the data reaches Y, a carry signal (f) is outputted from a data counter 10. At such a time, the B of the increment memory register 6 is selected, and the address of the head bit in the next scan line is calculated by the adder 7 and stored in the second address register 4. Thus, it is not necessary to write a dot image in the picture memory after rotation, and performance is improved in the case of rotational printing.
