Filed: 1994-09-29
Abstract: PURPOSE: To prevent the complication of constitution and to improve an extinction ratio characteristic without impairing the characteristics of driving voltage by providing a light incident part or light exit part with a region of a small concn. of Ti atoms. CONSTITUTION: The front layer of a substrate 2a consisting of LiNbO3 is provided with waveguides 8 by incorporating a prescribed concn. of Ti atom therein. A light incident part 8a, a branching part 8b, phase modulating part 8c, a multiplexing part 8d and a light exit part 8e are formed in these waveguides 8. The light incident part 8a or the light exit part 8e is provided with a region of a low concn. of the Ti atoms. Setting of a refractive index distribution in such a manner that a TM mode is excited and a TE mode is put into the state of cut off is made possible, by which the coexistence of the TE mode component in the exit light is averted or the component is decreased down to a relative low level.  The easy formation of the waveguides simply by forming a prescribed mask shape in the photolithography thereof is possible in the case of production of the waveguides by thermal diffusion of Ti.

Title: Device for modifying shape of beam
Inventor: HONMOU HIROSHI
IPC: C30B25/10
Filed: 1983-12-14
Abstract: PURPOSE:To form a high-quality single crystal film having large crystal particle size, by dividing a light beam into ordinary ray and extraordinary ray with a birefringence plate, and placing an element to deflect the direction of the polarization plane of ordinary ray or extraordinary ray by a specific angle to the emission side of the birefringence plate. CONSTITUTION:The laser beam 1 is divided into the ordinary ray 3 and the extraordinary ray 4 by passing through the birefringence plate 2. The ordinary ray 3 is a linearly polarized light having an electric field oscillating perpendicular to the plane of the paper, and the extraordinary ray 4 is a linearly polarized light having an electric field oscillating parallel to the plane of the paper. The plane of polarization of the ordinary ray 3 is different from that of the extraordinary ray 4 by 90 deg.. Accordingly, when the phase of the extraordinary ray is shifted by 180 deg. by passing the ray through the half- wave plate 5, the plane of polarization of the extraordinary ray is deflected by 90 deg., and the extraordinary ray 4 is converted to the linearly polarized light 6 having an electric field oscillating perpendicular to the plane of paper similar to the ordinary ray 3. An ordinary ray 3 and a linearly polarized ray 6 having the same plane of polarization can be obtained by this process, and the obtained light beam has double-humped cross-section.

Title: Catching detecting method of power window device
Inventor: MIURA YUKIO
IPC: E05F15/16
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To quicken detection by a means at low cost by calculating motor load torque by using a time table when the catching of a window is to be detected. SOLUTION: When the catching of a window is detected by a micro-control unit MCU, motor load torque is used as a parameter value employed for detection, the voltage fluctuation of a motor driving section 3 is added naturally when motor load torque is computed, and accurate detection is conducted without considering the voltage fluctuation of the motor driving section 3 when catching is detected. Since the MCU calculates load torque by using a first time table 1, in which the dependence item of motor driving voltage is stored, and a second time table 2, in which the dependence item of edge intervals is stored, detection calculating speed can be made steeply larger than motor torque is arithmetically operated discretely, and the catching of the window can be detected at high speed.
