Title: Polarizer beam splitter and its production
Inventor: KATAYAMA RYUICHI
IPC: G02B27/28
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a polarization beam splitter with which a high efficiency is obtainable even if only either of +1st order diffracted light, and -1st order diffracted light is utilized and production is easy and a process for producing the same. SOLUTION: Proton exchange regions 2 having staircase-like sections of 2<n> stages ((n) is an integer of >=2), for example, 4 stage, of depths are formed on the front surface of a lithium niobate substrate 1 having an optical axis within the plane. Phase compensation films 3 having four stages of periodically formed staircase-like sections are formed on these proton exchange regions 2. Of incident light 5, the polarized light component (ordinary ray component) perpendicular to the optical axis 4 transmits the polarization beam splitter and turns to transmitted light 6. The polarizing plate component (extraordinary ray component) parallel with the optical axis is diffracted by the polarization beam splitter to induce the +1st order diffracted light 7.  The efficiency of the +1st order diffracted light is, therefore, high and the efficiency in the case the diffracted light is used is enhanced.

Filed: 1988-09-21
Abstract: PURPOSE:To ensure that an analog waveform line to be drawn is drawn as s uniform line by a method wherein at the time of moving a printing head from one plotting point to the next, the head is once moved in the opposite direction to provide an approaching section, and then the head is moved at a fixed velocity between the plotting points. CONSTITUTION:First, input signals are taken into a controlling circuit 13, and a target position Xa for a head 8 and a feed quantity for a recording paper (p) are calculated. A motor 11 is rotated reversely, whereby the head 8 is moved reversely by an approaching section DELTAx. Immediately upon the reverse movement, the head 8 is started moving toward the target position Xa. The approaching section DELTAx is so set that the head 8 started moving toward the target position Xa can be moved at a fixed velocity after the time t* when the head 8 is passed again through its initial position X0. After the head 8 is passed through the initial position X0, the head 8 jets ink droplets toward the paper (p) at predetermined intervals, thereby plotting an analog waveform line. Because the head 8 is being moved at the fixed velocity at the time of plotting, the plotting density of the line is uniform over the entire length thereof, without any breakage or partial dot gaining.
