Title: Solid-state image sensing device
Inventor: MATSUMOTO SHIGENORI
IPC: H04N5/335
Filed: 1986-06-17
Abstract: PURPOSE:To form a photodiode, in which an afterimage phenomenon is hardly generated, by shaping an insulating film containing ions in a partial region in the main surface of a semiconductor substrate and using the partial region as the photodiode. CONSTITUTION:Ions having fixed positive charges are introduced into the film of an silicon dioxide film 5, thus forming a photodiode. A depletion layer is shaped without requiring the application of voltage from the outside in the vicinity of the surface of a P-type silicon substrate 1, and electrons in electron- hole pairs generated by light projected from the surface of the photodiode are stored in the depletion layer and employed as signal charges. When signal charges are read to a transfer channel 4, complete transfer can be realized easily by sufficiently increasing voltage applied to a transfer gate 6 because electrons as signal charges are stored as minority carriers. Accordingly, an afterimage phenomenon is removed completely.

Title: Crt display device
Inventor: YAMADA HIROSHI
IPC: G09G1/04
Filed: 1988-06-08
Abstract: PURPOSE:To effectively prevent fluctuations on the display screen of a CRT due to an external magnetic field with simple constitution by detecting fluctuations of a point displayed at a specific position on the display screen and controlling a deflecting means so that the point display stops. CONSTITUTION:The point displayed at the specific position 11 on the CRT 1 stops when there is not the influence of the external magnetic field. A two-dimensional optical sensor 4 outputs a signal corresponding to the point display position to a correcting circuit 5. When the display is affected by the external magnetic field, the light of the sensor 4 fluctuates together with the image plane of the display area 10, so variation of the display position fluctuating with time is found. The correcting circuit 5 receives a signal indicating the point display position from the sensor 4 and calculates a correcting signal for stopping the point and when the signal is applied to a deflection control circuit 23, the point position stops. The fluctuations on the display screen are prevented effectively by the simple constitution without using any shield case.

IPC: G03B27/73
Filed: 1992-06-02
Abstract: PURPOSE:To stably obtain proper copy conditions for individual original images with high precision by finding an exposure quantity on the basis of image characteristic vectors consisting of statistic values obtained by specific statistical processing after pieces of digital image information by colors are divided into plural areas by common mask processing. CONSTITUTION:Image signals 22a-22c which are supplied from an image pickup part 10 are selected with an analog switch 30, sampled by a sample holding circuit 31 and an A/D converter 3, and obtained at an LUT 34 as logarithmically converted digital image signals which are proportional to the transmissivity of an original image. The four colors B, G, R, and N (neural color) which are thus obtained are divided into plural areas by, for example. an equal dividing method or histogram dividing method. Then a mask image from the shadow part to the highlight of a subject is generated and statistically processed by the divided areas to find divided image characteristic vectors, which are weighted in consideration of the visual sensation characteristics of the human being to find exposure quantity vectors, thereby generating a copy image of the color image. Therefore. optimum copy conditions can stably be obtained with high precision without reference to characteristics, development and storage conditions, etc., by the quantity of a photographic film.

Abstract: PURPOSE: To reduce exposure to radioactivity by checking the corrosion of the stud bolt with a protective cap having a seal mechanism mounted to the lower end of the stud bolt through a female thread cut thereinside such a manner as to be partly engaged with the stud bolt sufficiently covering the bolt.  
     CONSTITUTION: Where a well 16 of the reactor is filled with water after a top cover 12 is removed from the pressure vessel of the reactor, a stud bolt 13 remains attached to a flange 17 of the pressure vessel. A cap 14 is made cylindrical in size necessary and enough to cover the stud bolt 13 and a female thread is cut in the inside thereof at a portion corresponding to a thread section of the stud bolt 13 in such a manner as to match thereof. This enables complete isolation of the stud bolt from the water thereby checking the corrosion of the bolt. In other words, since the water pressure for sealing is no higher than about 1 kg/cm 3 , sealing is possible with the slight torque by which the cap 14 can be clamped to the stud bolt.
