Title: Core internal structure of nuclear reactor
Inventor: HIDA KAZUTAKA
IPC: G21C7/22
Filed: 1990-08-21
Abstract: PURPOSE:To contrive the improvement of reliability and safety of scram by integrating fuel assembles to open clearances one another, dividing into a plurality of fuel assembly blocks arranged as liquid tightness is held and introducing water capable of water level adjustment to the clearances among these fuel assembly blocks. CONSTITUTION:A reactor core 4 is divided into four fuel assembly blocks 21 by a cruciform control area 22. Thirty nine fuel assemblies are integrated in each block 21 and one control rod is inserted and removed among the four fuel assemblies except for the circumferential part of the reactor core 4. When the emergency shutdown of a nuclear reactor is performed in an output operation state, a valve 27 is opened. At this time water 29 of room temperature is pushed by high pressure gas from an injection tank 28 is rapidly introduced into the control area 22 through the valve 27 and a feed water tube 26. As a result, because steam filled in the control area 22 is cooled by the water 29 of room temperature to condense, the pressure of the control area 22 is lowered rapidly and coolant is quickly allowed to flow from a lower plenum 7.

Abstract: PURPOSE:To miniaturize an instrument and to reduce power consumption, and a cost by counting the frequency of a rectangular pulse signal outputted by an oscillating means. CONSTITUTION:A rectangular wave pulse oscillator 1 consists of an inverter element 7, a resistance element 3, and a humidity detecting element 5.

Title: Method of inserting elastic body into hole drilled in plate material
Inventor: SHIRAGAMI MINORU
IPC: B23P19/02
Filed: 1989-08-28
Abstract: PURPOSE:To insert an elastic body unforcedly, promptly and smoothly into a hole drilled in a plate material by compressing and pushing out the elastic body halfway along a guide hole with a thrust rod. CONSTITUTION:An elastic body 3, when pushed with a thrust rod 21, slides along the slope 8b of a guide hole 8, and is compressed toward the center of the guide hole 8 and tapered through a hole 2 as moving toward the hole 2 of a plate material 1. When one flange 3b of the elastic body 3 passes through the hole 2 and its neck 3a tightens at the hole 2, the flange 3b expands by elastic restoring force, which prevents the elastic body 3 from coming out in the direction opposite to the pushed direction. Then when a guide piece 7 shifts in radial directions, the other flange 3c expands by its elastic restoring force to hold the elastic body 3 fixed not to come out of the hole 2 or the plate material 1 in either of the directions.

Title: Divider for linear interpolating device
Inventor: UEDA TOMOAKI
IPC: G06T11/20
Filed: 1985-10-01
Abstract: PURPOSE:To shorten the time necessary for division by executing a subtraction trial obtaining data required for linear interpolation up to the prescribed digits which insures errors against arising on an integer fraction in a state where the prescribed number of addition times necessary for linear interpolation is executed. CONSTITUTION:An exponential fraction data Na included in a dividen data A is inputted to a counter 6, whereby the number of subtraction trial time made by an adder circuit 5 is controlled to be (Na+2) times. When the circuit 5 carries out the subtraction action by times (Na+2) regulated by the contents in the counter 6, a quotient with (Na+2) digits covering 2<(>N<a->N<b)> to 2<-(>N<b+1)> can be obtained. The linear interpolating device matches the obtained quotient to the exponential fraction data Nb of the inputted data B as divider data and adds data by times from 2N<b> to 2<-(>N<b+1)>. Even if the quotient obtained as data with 2<(>N<a->N<b)> digits and 2<-(2>N<b+1)> digits is added by said times, the integer fraction will not pose errors, and precise coordinates at each division point can be available.

Title: Block distortion removing filter, image processor, and filtering method for image signal
Inventor: OOSA KINYA
IPC: H04N19/00
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To sufficiently remove even block distortion which is small in a difference value of a signal at a border of a block without spoiling a high--frequency component of a source image. SOLUTION: When a pixel signal included in pixel blocks forming one image is supplied, a detection part 1 detects a difference in pixel signal level at the periphery of the border of pixel blocks. This difference is compared by a threshold value decision part 2 with a reference value. According to the result of the comparison, an adder 5 adds a specific addition value to the pixel level at the periphery of the said block border. When the specific addition value is added, a random number is generated and based on this random number, a pattern containing the said specific addition value is selected out of addition value patterns. Consequently, the regularity of the difference value at the border of the pixel blocks is disordered and the block distortion generated between pixel blocks can be removed.
