The inactive area of the main surface of the layer 2 is removed by isotropic etching by using the mask 23 and a separating groove 21 is formed to an area regulated by the mask 23 and the section below the end section of the mask 23. After the part of the groove 21 below the end section of the mask 23 is filled with an insulating film 5B selectively formed by a depositing method, a silicon oxide film is formed on the surface of the groove 21 by an oxidizing method and an element separating insulating film 5 is formed on the silicon oxide film. At the time of forming the film 5, the part of the groove 21 below the end section of the mask 23 is filled with an insulating film 5A so as to reduce the oxidized quantity in the lateral direction. Therefore, stress concentration at the end section of the film 5 can be relieved and occurrence of defective crystals in the active area of the epitaxial layer can be reduced.

Title: Image monitor device
Inventor: KATSUTA SEIJI
IPC: G08B21/00
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To send a necessary number of images corresponding to the kind of abnormality to a guard center by discriminating the abnormality kind and controlling the number of images sent out according to the abnormality kind. SOLUTION: An image sensor 2 input images of a monitor area from an image pickup means at specific intervals of time and stores them in a sequential image storage area. Then the latest image which is inputted is compared with the reference image for trespass abnormality decision making in a reference image storage area. The image sensor 2 once detecting trespass abnormality rewrites only three frame images newly from the image memory at the time of the abnormality detection in an image memory. The image sensor 2 when receiving a state call signal from a controller 1 sends a trespass abnormality signal to the controller 1. Then the three frame images before the abnormality detection which are stored in the sequential image storage area and seven frame images after the abnormality detection, i.e., 10 images in total are sent out to the controller 1. The controller 1 receives those accumulated images and sends them to the guard center 7.

Abstract: PURPOSE:To prevent a delamination accident by incorporating a compd. (alkyl polysiloxane having a polyoxyalkylene chain at the side chain) into a back layer coated on the surface of a base on the side opposite from an image receiving layer. CONSTITUTION:First the polysiloxane compd. (alkyl polysiloxane having a polyoxyalkylene chain at the side chain) is incorporated into the coating layer of the back layer coated on the surface of the base on the side opposite from the image receiving layer in the formation of an image receiving sheet. A photosensitive sheet formed by coasting the respective layers on a transparent polyethylene terephthalate base and a processing liquid are then prepd. The photosensitive sheet is exposed through a color test chart. The image receiving sheet is superposed thereon and the processing liquid is developed between the two sheets to 65mu thickness. The processing is executed at 25 deg.C. The photosensitive sheet and the image receiving sheet are stripped in 90sec after the processing. The delamination accident is prevented by the addition of the polysiloxane compd. to the protective layer even if the image receiving sheets are left in the state of superposing the image receiving layer side and back layer side thereof.

Title: Antenna for small sized radio equipment
Inventor: KUDO KAZUHIRO
IPC: H05K3/46
Filed: 1987-09-16
Abstract: PURPOSE:To ensure a sufficient gain even for a small sized and thin profile radio equipment by using part of a display part as a major component of the small sized radio equipment. CONSTITUTION:The titled antenna consists of a feeder 3, a ground plate 2, a reflecting plate 8, a conductor plate 7 and a short-circuit plate 6 to form an inverse-F shaped modified antenna. The feeder 3 is connected to a receiver circuit of a circuit board 4 from the reflecting plate 8. The antenna part and the circuit system of the receiver are shielded by the ground plate 2 and the LCD 1 has a structure adhered closely to the rear face of the reflecting plate 8 when viewed from the antenna, then the electromagnetic effect is less. Thus, since the short-circuit plate 6 is designed to provide a reactance to compensate the capacitive component by the conductor plate 7 for the purpose of decreasing the resonance frequency of the antenna, although the width of the plate 6 is made thinner than the width of the conductor plate 7, the LCD connection part 5 connects the LCD 1 and the circuit board 4 along the short-circuit plate 6, then the effect of the LCD connection 5 given onto the characteristic of the antenna is less.

Filed: 1989-09-05
Abstract: PURPOSE:To simplify a calculation formula and to reduce the number of times of calculation by using coordinates of five points in a simplified mapping block to correct the inclination of a reception picture due to the attitude of a satellite by easy calculation. CONSTITUTION:A grid point extracting part 1 extracts coordinate data of the central grid point and grid points due south, due north, due east, and due west from this point from the simplified mapping block. An inclination calculating part 2 calculates an inclination Dlambda of the north-south axis and an inclination Dphi of the east-west axis in accordance with coordinate data extracted by the extracting part 1. A grid point correcting part 3 uses coordinate data Xc and Yc of the central grid point extracted by the extracting part 1 and inclinations Dlambda and Dphi calculated by the calculating part 2 to correct distributed coordinate data X and Y and outputs corrected coordinate data (x) and (y). A picture data transposing part 4 writes picture data corresponding to distributed coordinate data X and Y of the grid point in the address of data (x) and (y) of a storage device to transpose picture data. Thus, the inclination of the reception picture is corrected.
