Title: Core and fuel assembly of reactor
Inventor: YAMAOKA MITSUAKI
IPC: G21C3/30
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of core diameter by making void coefficient negative without drastically lowering the height of core. SOLUTION: In a core of reactor constituted by arranging long size fuel assemblies 2 and short size fuel assemblies 3 in a square grid, the long size fuel assemblies comprise axial blankets 4 at the upper and the lower parts of the long size fuel parts and the short size fuel assemblies 3 comprise water excluding vessels 5 at the upper part of the short size fuel parts and axial blankets 4 at the lower part. The water excluding vessel 5 is provided with a gas purge hole at the upper part and a coolant inlet hole at the lower part.  As steam stagnates in the water excluding vessel 5 in normal operation and excludes cooling water, neutron leak from the water excluding vessel 5 is enhanced during increasing of void coefficient in the region outside the water excluding vessel 5, which maintains the pressure in the water excluding vessel 5 equal to the reactor pressure, and reactivity variation during power rising is suppressed.

Title: Oscillating circuit
Inventor: MIYAGAWA YOUICHI
IPC: H03B5/36
Filed: 1981-10-28
Abstract: PURPOSE:To decrease a current consumed in an oscillation circuit, by respectively providing a positive feedback current means for P and N-MOS increasing the current flowing to the oscillation circuit, when a current flowing to a waveform shaping circuit is increased. CONSTITUTION:When a P-MOS 11 turns on at the oscillating state and a current flows to P-MOSs 7, 9, an output terminal 2 approaches a high potential and a current flowing to P-MOSs 8, 10 and 12 is decreased. Thus, the current flowing to the P-MOS 7 can not be increased but decreased. The operation of the N- MOSs is the same. Thus, an oscillation current and an output voltage generated at the output terminal can be suppressed to a preset value or below. The current consumed in th oscillation circuit can be decreased.

IPC: G06K9/62
Filed: 1983-09-19
Abstract: PURPOSE:To increase the processing speed of a pattern recognizer with a simple constitution by recognizing an input pattern with the collation carried out between the feature of the input pattern which is decided as the linear conversion of the input pattern and the feature of a register pattern decided as the linear conversion of the register pattern. CONSTITUTION:A linear conversion circuit 3 applies the 1st linear conversion to a register pattern of each category or the feature extracted from the register pattern together with the 2nd linear conversion which is defined as a product with the conversion carried out in accordance with the 1st linear conversion. A normalizing circuit 4' obtains a normalizing constant from the input and the output of the circuit 3. Then the secondary feature given from the circuit 3 and the output sent from the circuit 4' are stored to a dictionary part 5 with identification for each category. While a preprocessed 6 input pattern is scanned both horizontally and vertically to extract 7 the features, and the output of this extraction is sent to a collation circuit 8. The circuit 8 compares the output of a feature extracting circuit 7 with the output of the part 5. Then the collation is given between the result obtained by applying the 1st linear conversion to the feature of the input pattern and the result obtained by applying the 1st linear conversion to the feature of the register pattern to decide an input pattern.

IPC: H01L27/146
Filed: 1993-06-18
Abstract: PURPOSE:To fabricate an amplifier type solid state image sensing element, in which the transistor for peripheral circuit has LDD structure, through reduced number of steps. CONSTITUTION:Poly-Si 24 and SiO2 25 are deposited sequentially on the entire surface wherein the poly-Si 24 forms the gate electrode at an image part 12 and the SiO2 25 forms the side wall of gate electrode at a peripheral circuit part 13. A transistor 23 is formed into LDD structure through the use of Sin. 25 at the peripheral circuit part 13 and an impurity layer 26 is formed through the use of SiO2 at the image part 12.

Title: Composition containing aluminum phosphite, its manufacture, and rust preventive pigment
Inventor: ISE YOUTAROU
IPC: C09C1/40
Filed: 1980-12-09
Abstract: PURPOSE: To obtain a nonpollution rust preventive pigment consisting of aluminum phosphite and unreacted alumina hydrate by reacting phosphorous acid with alumina hydrate.  
     CONSTITUTION: A composition contg. aluminum phosphite represented by general formulaI(where (n) is a variable) is produced according to expression II by dispersing alumina hydrate in an aqueous soln. of phosphorous acid and heating the dispersion to about 70°C with stirring. Alumina gel, bayerite, boehmite or the like may be used as starting material. As the molar ratio of 3H 2 PHO 3 /Al 2 O 3  becomes closer to 1, and in order to react Al 2 O 3  particles up to the cores, longer time is required. Rust preventing action is due to Al 2 (PHO 3 ) 3  formed on the particle surfaces, so the effect is shown when said molar ratio is ≥about 0.5. When said molar ratio exceeds 1, the reaction in the acidic soln. is accelerated, yet washing for removing H 2 PHO 3  is required after the reaction.

Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To prevent character information from being lacked by recalculating a character size, a character pitch and a line feed width such that the output character size is maximized in a reduced character region based on the character size, character pitch and line feed width of an input character data. SOLUTION: When a reduction rate of a reduction rate input section 203 is inputted at a character data processing section 206, a reduced character size is calculated using the character size information and reduction rate in a character data. A character size comparing section 207 compares the reduced character size thus calculated with a limit value stored in a limit value holding section 208 and if the reduced character size is smaller than the limit value, a reduced character size reconfiguring section 209 recalculates a character size, a character pitch and a line feed width such that the character size is maximized in a reduced character region based on the character size, character pitch and line feed width of an input character data.
