Patent JP-S63202722-A (JP)
Title: Optical switch
Inventor: WAKAO KIYOHIDE
IPC: G02B6/12
Filed: 1987-02-19
Abstract: PURPOSE:To miniaturize an element by forming waveguides in a crossing part to the thickness smaller in a current implantation region than in the other regions, inducing total reflection by a small change in refractive index by current implantation and increasing a crossing angle. CONSTITUTION:For example, the current implantation region in the crossing part of the waveguides is formed to the thickness d2=0.7mum smaller than d3=0.8mum in the other regions. The total reflection does not arise with the equiv. refractive index change component DELTAnb in the thin part of the waveguides while no electric current flows to the current implantation region. Light of a port 1 is thus emitted to a port 3. The refractive index decreases by as much as the refractive index change component DELTAna by a plasma effect and the total reflection is induced when the current is passed to the current implantation region. The light of the port 1 is then emitted to a port 4. The total refractive index change component increases to DELTAn=DELTAna+nb and the intersecting angle thetaof the waveguides is increased. The element is, therefore, miniaturized.

Title: Printer
Inventor: MOJI YOSUKE
IPC: B41J35/16
Filed: 1989-02-16
Abstract: PURPOSE:To enhance a cueing accuracy of a multi-color ribbon and to contrive a high-speed processing by a method wherein a motor is controlled so that the multi-color ribbon is taken up in a first frequency when a ribbon take-up reel diameter is less than a predetermined value, and in a second frequency lower than the first frequency when it becomes the predetermined value or more. CONSTITUTION:Since a ribbon take-up running speed increases in proportion to a take-up reel diameter, a motor rotating frequency phim1 is reduced to phim2 when a take-up reel diameter D increases to Dn to prevent a ribbon running speed upsilon from being more than upsilon0 even when the take-up reel diameter D reaches a maximum value Dmax. The value Dn can be easily estimated because it is inversely proportional to a pulse number Ny in feeding a Y detection mark 7a. Namely, when a count value of a counting means 2 during the detection of the detection mark by a sensor 14 is more than a specific value, a take-up reel diameter smaller than Dn is judged, and a motor rotating frequency phim1 is determined. On the contrary, when it is not more than the specific value, a take-up reel diameter of Dn or more is judged, and a motor rotating frequency phim2 is determined.
