Title: Optical fiber type current sensor
Inventor: MORIZAKI SUMIKO
IPC: G01R33/032
Filed: 1985-09-17
Abstract: PURPOSE:To make it possible to prolong the length of a Faraday material without increasing the transmission loss of a sensor, by receiving two lights having the same characteristics as signal lights by one output optical fiber. CONSTITUTION:The light lin incident on rutile flat plate (double refraction material) 8 from the input optical fiber 1 arranged on the optical axis a-a' of a self-converging rod lens 3 is polarized to be separated into a normal light l1 and abnormal light l2 and passes through a Faraday material 6 and a 1/4 wavelength plate 9 to be reflected by a reflective plate 7 while the reflected light again passes through the wavelength plate 9 and the material 6 to be again incident to the flat plate 8. Two lights l1, l2 incident again are polarized to be separated into normal light and abnormal light to obtain four lights l11, l12, l21, l22. Because the lights l12, l21 reaches to the side end surface of the flat plate 8, that is, the point separated by a polarizing/separating width from the position of the optical fiber 1 to the polarizing/separating direction of the flat plate 8, said two lights are simultaneously received by an output optical fiber 2. The angle formed by the optical axis of the 1/4 wavelength plate 9 and that of the double refraction material 8 is set to about 22.5 deg.+npi/2 (n: an integer).

Title: Mos type semiconductor device
Inventor: TAKENAKA KAZUHIRO
IPC: H01L29/78
Filed: 1987-08-18
Abstract: PURPOSE:To prevent field concentration at an edge part and breakdown strength from decreasing and to increase breakdown strength of the drain, by covering entirely a first diffusion layer of high concentration which constitutes the drain with a second diffusion layer lower in concentration than the first. CONSTITUTION:As for P-type substrate, an oxide film 2 for isolation is of LOCOS structure. A diffusion layer N<-> layer 6 of low density which becomes an offset portion is formed through a method such as ion implantation of phosphorus and annealing at N2 atmosphere after a poly Si electrode 4 is shaped. An N+ layer 8 is formed through ion implantation of phosphorus or thermal diffusion of POCL3 together with an N<+> layer 3 of source. Since an edge 12 of N+ layer is covered with an N<-> layer 6, the field concentration at the edge of N+ layer which developed conventionally can be eliminated and the drain withstanding voltage drop therein can be prevented. Because the bottom 13 of N<+> layer is also covered with the N<-> layer 6, the field concentration between the bottom of N<+> layer and P substrate can be reduced and the breakdown strength can be improved.

Abstract: PROBLEM TO BE SOLVED: To improve the precision of a description format and content standardization in every description element in a document by defining verification content in every kind of a control code attached into the document. SOLUTION: A processing part 102 analyzes if a control code exists in an input sentence after inputting a structured document that becomes input data and when it exists, it outputs results to the display of a computer, a printer, etc., after verifying a description element according to a content defined by a verification content definition table 103. In such a case, the table 103 uses the control code of a document description language applied to the structured document that becomes an object to be processed when the control code appears in the processing object document in order to specify what kind of viewpoint the verification of a description element is executed from. Thus, the control code which specifies a document structure and an element is attached to a document whose document structure is relatively regular, such as a created structured document by applying the document description language.
