Title: Polarization-independent optical isolator
Inventor: SUGIYAMA SHIN
IPC: G02B27/28
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To make an optical isolator of high performance, cabbage of being miniaturized and reduced in cost, by providing the double refraction crystal of a polarized light separating element to incline in a direction in which the angle formed by its optical axis and an incident light beam smaller to suppress the degradation of a signal due to multiple reflected lights and to exert a larger isolation characteristic. SOLUTION: In the change of a separation distance at the time when the optical isolator is inclined for the purpose of eliminating multiple reflected lights, the separation distance is increased or decreased depending on the positive angle or the negative angle of an incident angle, in short, the separation distance is changed by the inclination angle of the optical isolator. When the isolator has the same performance both in the positive inclination angle and the negative angle in order to suppress the multiple reflected lights, it is desirable to incline the element to a direction in which the enhancing of the isolation characteristic can be expected together with the suppressing of the reflected lights. The direction is a direction in which the angle formed by the optical axis θ of the double refraction crystal and the incident light beam θ' becomes small.  Moreover, it is desirable that this inclination angle is large as much as possible for the pupose of eliminating the multiple reflected lights, but when the effective diameter of the polarization-dependent loss element of a forward direction beam is considered, the angle of the range of 3 deg.∼5 deg. is suitable.

Filed: 1988-08-31
Abstract: PURPOSE:To increase the processing speed by performing the processing to develop vector data expressing outline information of a graphic character to a dot pattern by either of the curve approximating method using a curve function and the line approximating method using lines and substituting curve approximation with line approximation at the time of not especially giving importance to the quality. CONSTITUTION:When an output instruction related to vector data is received from the external, a vector data converting part 1 takes in corresponding data from a vector data storage part 2 to perform conversion of interpolation processing data. Converted data is processed by a vector data processing part 3 and is transferred to a dot pattern developing part 4, and the processing of development from vector data to dot data is performed in this part 4. That is, curve approximation using Bezier curve is expressed with line approximation. Since there is probability that the dot pattern is difficult to discriminate as shown in a figure (b) when curve interpolation is expressed with only line interpolation as it is, outline points and curve interpolarting points are successively approximated to lines as shown in a figure (c).

Title: Photodetection device
Inventor: FUJIWARA MASATOSHI
IPC: H01L31/0264
Filed: 1992-07-22
Abstract: PURPOSE:To eliminate nonluminous crystallization on the surface of the photodetection face of carriers and to reduce a signal noise by a method wherein a magnetic field is applied in such a way that minority carriers contributing to a signal are moved away from the surface of the photodetection face by a Hall electric field. CONSTITUTION:Since a magnetic field in a direction indicated by an arrow 2 is applied by a magnetic-field application means, a Hall electric field in a direction indicated by an arrow 3 is generated, and minority carriers contributing to a signal out of carriers in a photodetection layer 6 are moved away from the surface of the photodetection layer by the Hall electric field. Thereby, it is possible to realize a photodetection device wherein carriers which reach the surface of the photodetection layer to cause nonluminous recrystallization can be reduced sharply and a signal noise is small. In addition, since a vibrating magnetic field is applied in such a way that the magnitude of the Hall electric field is changed periodically, only an electric signal component can be provided with the same frequency aa the vibrating magnetic field. When only a signal of the frequency is detected selectively, it is possible to obtain the signal from which a noise component having no frequency has been removed.
