Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To reduce the size of an ultra-micro floating gate semiconductor storage device having areas which function as bit lines on a substrate side and adopting a buried element separating system to an ultra-micro size. SOLUTION: In an Si substrate 1, buried conductor films 2 which function as source-drain areas and bit lines, diffusion layers 3, and buried separating insulating films 7 are provided. On the substrate 1, a gate insulating film 4, floating gate electrodes 5, a capacitor insulating film 8, control gate electrodes 6, gate top insulating films 11, side-wall insulating films 12, tunnel insulating films 10, and an erasing gate electrode 9 are provided.

Title: Method of updating pattern-matching-network
Inventor: MAASHIYARU AI SHIYOO
IPC: G06N5/04
Filed: 1989-07-27
Abstract: PURPOSE: To speed up processing by caching a value that is given by a variation token argument in a loop when the value is constant and making good use of it for subsequent test repetition, and eliminating the need for recounting. CONSTITUTION: A program 11 executed by a digital computer having an internal memory 13 is arrayed as a matching network program. Whether or not there is a test to be conducted between a change token and a partial match token is inspected as to one predetermined node. When it is decided by the inspection that there is the test and there is no variation in value in the test, the change token value is calculated for the 1st repetition of the test, the change token value is temporarily stored as to a node, and the temporarily stored change token is used as to subsequent repetition of the test. When there is a change during the test, a change token argument value is calculated each time the test is repeated. Consequently, all recalculations for input are evaded and RETE operation is improved.

Filed: 1987-07-31
Abstract: PURPOSE:To make it possible to form a high breakdown strength and highly reliable insulating film by a method wherein nitrogen ions are implanted by an ion-implantation method at the time of formation of an Si nitride layer to form the Si nitride layer. CONSTITUTION:An Si substrate 4 is thermally oxidized and the surface of a thermal oxide film 1 is nitrided using nitrogen (n, n) ions. Here, an energy within a range of 40-200eV is desirable as the energy of the nitrogen ions. Then, a steam oxidation is performed to oxidize the surface and a surface oxide film 3 is formed. Thereby, hydrogen atoms, which cause the deterioration of characteristics, can be decreased and moreover, a film having comparatively more the inherent composition ratio, Si3N4, of an Si nitride film 2 can be formed by the intensity of the reactivity of the ions and the low kenetic energy of 40-200eV of the ions and the breakdown strength of a device is improved.

Title: Method for confirming function of brake for control rod driving apparatus
Inventor: NAKAMURA AKIRA
IPC: G21C7/12
Filed: 1990-07-23
Abstract: PURPOSE:To confirm the function of a brake by detecting the presence of rotation by starting the electromotor of a control rod driving apparatus in such a state that output torque is limited. CONSTITUTION:When a test for confirming the function of an electromagnetic brake 20 is performed, the output of an electromotor driving control apparatus 100 is connected to a current limiter 101 to limit the output torque of the electromotor 7 and the electromotor 7 is started in such a state that the function of the brake is released. The current limit value of the current limiter 101 is set so as to become larger than the value of the output torque of the electromotor 7 acting on a screw shaft 12 when piping 18 is broken and smaller than the rated holding torque of the brake 20. The electromotor 7 is started in this state and, when the electromotor 7 is not rotated at this time, it is cleared that the brake 20 has torque equal to or more than the falling torque of control rods. When the electromotor 7 is rotated, it is cleared that the function of the brake is deteriorated and, therefore, the function of the brake 20 can be confirmed in such a state that the brake 20 is mounted on a control rod driving apparatus 3.

Filed: 1989-07-26
Abstract: PURPOSE:To remove the generation of distortion at the time of manufacturing a yoke piece and prevent the occurrence of turbulence of magnetic flux distribution within a magnetic circuit at the time of use by forming a clip fixing part in such a manner as to be protruded from the yoke piece. CONSTITUTION:A deflection yoke is obtained by installing a clip 3 to each protruding part 4a, 4b at the time of final assembling after insertion of a coil, and integrally fixing two yoke pieces 1a, 1b. The protruding parts 4a, 4b forming clip fixing parts have protruding structures protruded to the outside of the yoke pieces 1a, 1b. Therefore, generation of distortion at the time of manufacturing the yoke pieces can be removed, and also, as the yoke pieces 1a, 1b have no locally thinned part, turbulence of the magnetic flux distribution in a magnetic circuit never occur at the time of use, and the magnetic flux can be uniformed.

The roller 30 and glass 1 are maintained in a minute gap size 'delta'. For such a reason, at the time of reading the original, the roller 30 is made into a condition to abut on the back surface of the original 7, the original 7 can be prevented from floating from the surface of the glass 1, and the defocus can be prevented. Since the roller 30 is rotated, a dirt and a flaw due to a scratch by the original 7 cannot be generated.
