Title: Polarization controller
Inventor: OOTSUKA TETSUO
IPC: G02F1/139
Filed: 1979-11-19
Abstract: PURPOSE: To generate two linear polarized lights differing in polarization surfaces by using one linear polarizing plate provided at the incident side of light together with a twisted nematic liquid crystal cell and by applying an alternate low-frequency voltage and high-frequency voltage between the opposite electrodes.  
     CONSTITUTION: Between two glass plates 1 equipped with transparent electrodes 2, nematic liquid crystal changing in the sign of dielectric anisotropy according to the frequency of an applied voltage is injected and slanting angle (α) from the substrate surface of liquid crystal molecule 5 should be between 2 and 50°. As a voltage of a low frequency is applied with switch S, light passed through linear polarizing plate 4 passes through the liquid crystal layer without turning the polarization surface, so that linear polarized light parallel to the paper surface can be obtained. When a high-frequency voltage is applied with switch S, on the other hand, the light passed through linear polarizing plate 4 outputted with its polarization surface turned by 90° by the liquid crystal layer. Namely, the linear polarized light having the polarization surface perpendicular to the paper surface can be obtained.

Title: Print control device
Inventor: MASUYAMA TOMIO
IPC: B41J21/00
Filed: 1993-06-22
Abstract: PURPOSE:To print without dividing a character string into two times or more also in the case of bit pattern expanding method so as to improve printing grade by providing a driving means for driving a print head based on a printing data divided by a dividing means which divides at a height of a print head. CONSTITUTION:When a record signal is sent from a system bus, the record signal is converted into a recording data for printing in between a gate array 1704 and an MPU 1701. Motor drivers 1706 and 1707 are driven and a record head is driven in accordance with the recording data which are sent to a head driver 1705 so as to carry out recording. In the case of a document consisting of only characters, there is ordinarily a gap of 1 dot or more between lines. In that case, printing is performed by making the space from the top edge of the line to the gap 1 line, so that characters in each line are printed by one time of printing without fail unless a size of a character exceeds the size of the print head (64 dots in this case), thereby improving printing grade.

Title: Dynamic pressure air bearing type polygon scanner
Inventor: ITAMI YUKIO
IPC: G02B26/12
Filed: 1990-06-07
Abstract: PURPOSE:To prevent a mirror presser from shifting in position owing to a rise in temperature resulting from continuous operation and unbalance quantity at the same time by setting the coefficient of linear expansion of a material which constitutes the mirror presser <=1.2 time as large as the coefficient of linear expansion of a material which constitutes a hollow rotary shaft. CONSTITUTION:For example, stainless steel, carbon steel, etc., are used as the material of the mirror presser 5 and its coefficient of linear expansion is set nearly equal to or less than, i.e. <=1.2 times as large as the coefficient of linear expansion of the material of the hollow rotary shaft 1. Then the hollow rotary shaft 1 is made of stainless steel, e.g. SUS420J2, so stainless steel or carbon steel whose linear expansion coefficient is nearly 1.2 time as large as that of said SUS420J2 is selected. Therefore, the applied pressure of thermal expansion due to the temperature rise resulting from the continuous operation is not generated and the mirror presser 5 is prevented from shifting radially. At the same time, the increase in the unbalance quantity of a rotary body 8 is eliminated and the rotary body 8 rotates extremely silently and smoothly.
