IPC: D01H1/36
Filed: 1992-05-15
Abstract: PURPOSE:To properly vary the rotational speed of a bobbin corresponding to the spinning condition for each increase of the number of wound roving layers by automatically calculating the decrease of the rotational speed of the bobbin by the increase in the roving layers corresponding to the spinning condition. CONSTITUTION:A program memory 28 stores a data base to calculate the decrease in the rotational speed of a bobbin for the increase in the number of wound roving layers as a function of variables such as the weight of roving, the kind of fiber, the rotational speed of a flyer and the wound number of a presser. The decrease in the rotational speed corresponding to the increase in the number of the wound roving layers is calculated by a CPU 27 based on the spinning conditions inputted by an inputting apparatus 29 and the data base stored in the program memory 28. The winding motor 11 is decelerated by a control signal transmitted from the CPU 27 corresponding to the increase in the number of roving layers and the rotational speed of the bobbin is decreased by a prescribed decrement.

Inventor: KOMAKI YASUSHI
IPC: F23C99/00
Filed: 1993-04-28
Abstract: PURPOSE:To provide a burner device wherein the generation of carbon monoxide and the production of nitrogen oxides are little. CONSTITUTION:First burners 1 and second burners 2 are alternately arranged, and respective flame hole surfaces 5, 6 are so raised as to be formed into a V shape. A flame hole omitting part 16 on which there are not flame holes 3, 4 is provided on a center V-shaped base bottom part 17 of respective flame hole surfaces 5, 6. The low temperature flame base part of low density premixed gas to be injected from the second burner 2 is flame-held by high temperature flames of high density premixed gas to be injected from the adjacent first burner 1. And the low temperature flames receive heat of the high temperature flames to be stably burned, thereby its stable combustion is promoted. Moreover the combustibility becomes good by the retention effect where the upper side flames are pushed up by the lower side flames, and also the generation of CO is decreased. Moreover, since the just above part of the flame hole omitting part 16 becomes the evacuated zone in the combustion, the recirculating of combustion exhaust gas is performed, thereby the combustion becomes sluggish, so that the production of nitrogen oxides is restrained.
