Title: Method for producing large round-sealed quartz glass pipe, and device therefor
Inventor: ITO TOSHIHARU
IPC: C03B23/13
Filed: 1993-05-31
Abstract: PURPOSE:To obtain a large round-sealed quartz glass pipe having a high precision in a high productivity by fusing the end surface of a quartz glass pipe with a quartz glass disk, and subsequently charging a gas being controlled in pressure from the other end of the glass pipe to form the round part of the quartz glass pipe.

A quartz glass disk 3 is set to a rotation support means attached to the right end of the glass lathe so that the center of the disk 3 conforms with the center of the faced glass pipe 2. While the right rotation support means is laterally moved, the glass pipe 2 and the glass disk 3 are heated with an oxyhydrogen burner 5 to fuse with each other. While the integrated product is rotated, the surface to be roundly sealed is heated with the oxyhydrogen flame burner 5, and the pressure of a gas 10 charged from the other end of the quartz glass pipe 2 is simultaneously controlled to form the round sealed surface as a round part having a specific curvature, thus providing a desired large round sealed quartz glass pipe.

Abstract: PURPOSE:To reduce the consumption of a ribbon to 1/n (n is a positive integer) of that in a standard case, by a construction wherein a standard taking-up function for taking up a ribbon by a predetermined amount for each predetermined amount of printing and a ribbon-saving taking-up function for taking up the ribbon by an amount equal to 1/n of the predetermined amount are switchably provided. CONSTITUTION:Where the ribbon-saving taking-up function is selected, a CR motor is driven until the number of CR driving steps becomes 0, whereby a carriage is returned to an original printing-starting position. However, a ribbon motor is driven until the number of ribbon-driving steps (RDS) becomes 0. The number RDS is set to be 1/n of the number of the CR driving steps. Accordingly, the ribbon 12 is taken up by 1/n of the amount used for printing, namely, it is taken up by the amount of l/n.

Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To suppress an increase of steering force caused by the assist-off state occurring on a steering system of a transmission ratio variable mechanism and a steering force auxiliary mechanism by changing the transmission ratio of the transmission ratio variable mechanism to a larger value with a transmission ratio setting means based on the travel state of a vehicle when the steering force auxiliary mechanism exceeds the prescribed operating speed.

If the vehicle speed V is higher than Vth, the value of the transmission ratio G is left as it is. If the vehicle speed V is a low speed lower than Vth, a correction coefficient K is set to a value larger than 1 when the steering speed dθh/dt exceeds a specified value in the steering direction specified with right steering as positive and left steering as negative (S 206), and the transmission ratio G is changed based on the arithmetic result K.G of the transmission ratio G and the correction coefficient K(S 208). The assist-off state can be prevented by setting the transmission ratio G to a larger value in a high-steering speed region.
