Filed: 1991-10-31
Abstract: PURPOSE:To improve a recognition rate by making it possible to correct a recognition error which is different from a position for which an analysis becomes impossible by dividing an analysis definition range and an error range and performing a processing to replace doubtful parts only within the error range. CONSTITUTION:For the output result of a character recognition part 1, a word collation processing and a morpheme analysis processing are performed in a word collation part 2 and a morpheme analysis processing part 3, respectively. At this time, when an analysis becomes impossible in the process of the morpheme analysis, an error range is decided in an error range decision part 4. When the error range is decided, most doubtful parts are corrected in an erroneous recognition correction part 5.

Title: Optical tuner

IPC: G02B13/18
Filed: 1987-11-12
Abstract: PURPOSE:To provide an optical tuner having a simple structure capable of receiving only the light of a necessary wavelength from plural wavelengths in a piece of an output optical fiber by providing an angle-adjusting mechanism to a holographic diffraction grating. CONSTITUTION:Five different signals from the input optical fiber 3 are entrained in the light consisting of five different wavelengths and is projected diagonally to the holographic diffraction grating 1 through an aspherical lens 2, by which the light consisting of the five different wavelengths is subjected to wavelength dispersion and is reflected at the angle varying with each wavelength. This light is condensed by the aspherical lens 2 and only the light of one wavelength N in the light of the different wavelengths is focused onto the end face of the output optical fiber 4. The light of the other wavelengths is not projected onto the output optical fiber. The light of the other wavelengths can, therefore, be received by adjusting the angle of the holographic diffraction grating by using the angle-adjusting mechanism consisting of a piezo-electric actuator 5, a fulcrum point 6 and a support 7 to project the light of the required wavelength on a photodetecting element and by converting said light to an electric signal.

Title: Semiconductor device, manufacture of the same, and semiconductor substrate
Inventor: KANAI AKIRA
IPC: H01L21/822
Filed: 1987-11-12
Abstract: PURPOSE:To form a semiconductor device of good electric characteristics without any crystal defect such as an oxidation stacking fault by a method wherein the direction of extension of orientation flat is coincident with the direction of an off-angle and the direction and orientation of a substrate inclination with respect to the orientation flat remain unchanged at all times. CONSTITUTION:A wafer 1 is provided in a direction where an orientation flat 3 is coincident with the direction of an off-angle. In a silicon crystal, the crystallizability of in above direction, i.e., in a direction equivalent to [100] plane demonstrates a lowest piezo resistance effect. Additionally, when a semiconductor device such as an active element is formed on the principal surface of the wafer 1, one side of a rectangular chip region 6 is laid out along the orientation flat. The direction of the orientation flat 3 demonstrates a lowest piezo resistance effect because the orientation of the crystal is equivalent to the [100] direction. Accordingly, the characteristics of a device pattern part is stabilized where the characteristics of the device are made unstable owing to diffusion resistance and the piezo resistance effect. Further, the present method presents the good use of the wafer without requiring a layout where the orientation of the formation of the diffusion resistance 7 in the formation of the semiconductor device is included.
