Title: Semiconductor device
Inventor: OKA KENJI
IPC: H01L27/06
Filed: 1979-01-31
Abstract: PURPOSE: To form two elements equivalently by a method wherein a quadrilateral region, with each of its vertices less than 180°, is divided into 4 regions by its diagonals, an element is provided in each region, elements in regions not adjacent to each other are electrically connected in parallel.  
     CONSTITUTION: In the J-FET, a square region, with all of its vertices being 90°, are divided into four regions, an element is formed in each of the resulting triangles, and two elements in regions not adjacent to each other are electrically connected. This J-FET is formed in the direction inclined by an angle θ" with respect to the inclination of the epitaxial layer. The distance between the two elements, x 0 , multiplied by √2/2 becomes the maximum for the channel distance x. But since x 0  is the distance between the two elements, it becomes very samll, so that the channel thicknesses of the two elements become almost the same for the deviation of the epitaxial layer in any direction.

Title: Pressure sensor
Inventor: HINATSU JIYUNJI
IPC: G01L11/00
Filed: 1985-01-25
Abstract: PURPOSE:To reduce the measurement errors caused by the concentrated stress of the members to constitute the press-contacting face by reducing the concentrated stress strength on the impressed surface of the external part pressure by the elasticity which is from this impressed surface upto the optical path of the center part. CONSTITUTION:A photoelastic element 13 is adhesively pinched between a diaphragm 6 and the spacer 7 being fixed to a sensor part. The pressure from the external part impressed on the diaphragm 6 is therefore transmitted to the photoelastic element 13 and due to the elastic deflection caused by this pressure the incident polarized light is subjected to a double refraction by the deflection existing between the crystals of the transferred optical path part. Now in order to reduce the bad effect due to the abnormal elastic deflection caused by the stress concentration the length A of the elastic element 13 is made bigger and the distance from the photodetecting face upto the optical path is extended. The elastic deflection caused by the uneven stress on the optical path is thus reduced and the polarized light is emitted between crystals in the state of smoothed elastic deflection.

Title: Television interphone
Inventor: HAGIO KENICHI
IPC: H04N7/18
Filed: 1993-01-26
Abstract: PURPOSE:To recognize an accurate image by providing an image distortion correcting means. CONSTITUTION:An address conversion means 5 enciphers the characteristic of the image distortion generated by the lens, etc., of a television camera, calculates an conversion address and preliminarily stores the integer part of the result in a memory table. The decimal part of the calculation result is made to be stored in an interpolation factor table 6 and is read as the interpolation factor at the same time when the memory table of the means 5 is accessed. If a high speed arithmetic circuit which is capable of performing a real number calculation of the conversion address by real time is used as the means 5, the integer part of the calculation result does not become necessary to be preliminarily stored in the memory table for address conversion, the decimal part does not become necessary to be preliminarily stored in the table 6, the integer part of the output of the arithmetic circuit as it is may be used as the convertion address and the decimal part as it is may be used as the interpolation factor. An accurate image can be obtained by obtaining a wide visual field by the super-wide-angle lens of the television camera of a slave machine and correcting a generated distortion.
