Title: Active optical isolator
Inventor: TAKARA HIDEHIKO
IPC: G02F1/09
Filed: 1990-06-29
Abstract: PURPOSE:To allow the control of the transmission and shut off of light and to allow the shut off of the light in an opposite direction in either case by providing an optically rotary element which can switch non-optically rotatory light and a double refractive crystal plate which separates ordinary ray and extraordinary ray between a polarizer and an analyzer. CONSTITUTION:Only the polarized light rotated 45 deg. with respect to the polarizer P of the light transmitted through a lens L2 from an optical fiber F2 is transmitted by the analyzer A (f). The polarized light transmitted therethrough is further rotated 45 deg. by a Faraday rotor F (g). Then, this polarization direction is an ordinary ray with a double refractive crystal plate B and, therefore, the light advances straight without being refracted by the double refractive crystal plate B. The exit light (h) from the double refractive crystal plate B is not changed in the polarization direction (i) as a voltage is impressed to the optically rotatory element R even if the light is made incident on this element. This light is shut off by the polarizer P and is not coupled to the optical fiber F1. The transmission and shut off of the light are electrically and arbitrarily controlled at need in this way and the light of the opposite direction is shut off in either case.

Filed: 1987-07-10
Abstract: PURPOSE:To enable easy recognition which part of a printed result is the part assigned a color not provided, by using a specified pattern such as a tiling pattern in place of the part assigned a color which is not provided and in which printing can not be performed. CONSTITUTION:An input/output controlling part 201 sequentially stores printing data into a page memory 202, and when preparation for printing is finished, a 'start printing' command is outputted from a host 100. A main controlling part 203 sequentially reads the stored data, checks color designation information, and when printing can be performed, the part 203 converts character data into pattern data by referencing a character pattern generating part 204, and stores the pattern data into a designated color dot pattern memory 205. When a color in which printing can be performed is not designated, the character code or the like is converted into a predetermined pattern, which is stored into a dot pattern memory 206. Subsequently, these pieces of data are stored into scan buffers 207, 208, and a printer engine part 300 performs printing by controlling reading controlling parts 209, 210 in response to the 'start printing' command. By this, printing data assigned a color not provided can be converted into a tiling pattern, thereby informing the operator that the relevant part in the printed result is assigned a color in which printing cannot be performed.
