摘要:
A method of preparing pattern information for a jacquard fabric produced on an electronically controlled knitting machine is disclosed. Yarn color information that is to be fed to yarn feeders for the courses in a knit fabric is prepared. This information is resolved into information for knitting and welting which is to be fed to different wales for each yarn feeder. Tucking information for the different colored yarns is separately prepared. This tucking information is resolved into tucking and welting pattern information. The knitting and welting information which is to be fed to different wales for each yarn feeder is combined with the separately prepared information on tucking and welting to form synthesized pattern information for knitting, welting, and tucking.

The shell main body for a muffler includes an inner shell in a cylindrical shape with a cross-section of an imperfect circle defined by small arc portions alternating with large arc portions; and an outer shell wrapping the inner shell and formed in a cylindrical shape similar to the inner shell. An end portion of the inner shell and an end portion of the outer shell are overlapped in a circumstantial direction of the shell main body to form a shell overlap portion that is capable of discharging vapor in a gap of the large arc portions formed between the inner shell and the outer shell into one of an outside and an inside of the shell main body. This shell overlapping portion is located in one of the small arc portions.

An object of the present invention is to provide a modifier for styrene resins that has excellent powder characteristics and that can provide a styrene resin composition for a styrene resin having high impact resistance and formability when the modifier is contained in a small amount.A modifier (C) for styrene resins that has improved powder characteristics can be obtained by mixing, in advance or in advance in latex form, 1 to 400 parts by weight of a styrene copolymer (B) with 100 parts by weight of a polyorganosiloxane-containing graft copolymer (A) having a polyorganosiloxane backbone produced by polymerizing an organosiloxane and a grafting agent, and then granulating the resulting mixture. Thus, the above-described object can be achieved.
摘要:
An electronic pattern circular knitting machine and method are provided in which a first encoder is operatively associated with the needle cylinder with which it rotates synchronously and generates a pulse signal for each knitting needle and transmits that signal to a central controller for the knitting machine, in which is stored a datum position for the first encoder, for comparison with pre-stored pattern data to calculate the position of each knitting needle; in which a second encoder is operatively associated with a dial and its cam system, the movement of which changes the knitting timing, for generation and transmission of a position signal to the central controller for comparison with a stored corresponding position to the datum position of the first encoder and a determination of whether the knitting timing has been changed and if so, to adjust automatically the needle selection timing.
