Title: Seismic sensor
Inventor: MORIYAMA HIROYUKI
IPC: G01H1/00
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain a unit for detecting vibration or impact due to earthquake or the like by making a decision whether the vibration level is higher than a set seismic level or not based on the detection output from a vibration sensor and producing a corresponding output or interrupting power supply to a load. SOLUTION: A microcomputer 26 converts variation in the frequency of a vibration sensor 25 into the variation of vibration and analyzes the vibration pattern. When the vibration has the vibration pattern of earthquake, the vibration level is determined and a corresponding seismic level is calculated. A decision is then made whether the seismic level thus calculated is higher than a seismic level set by a set switch 15 and when the former is higher, a corresponding relay output is fed to an output relay 27. The relay 27 has output terminals 7-9 connected with machines for which power supply must be interrupted on the occurrence of earthquake or a generator or alarm to be actuated on the occurrence of earthquake. On the occurrence of earthquake having seismic level higher than a set level, these machines are interrupted or actuated surely.

Title: Mask defect correcting method and mask defect correcting device
Inventor: OOKA MASATO
IPC: G03F1/72
Filed: 1994-03-17
Abstract: PURPOSE:To correct chromium defect without resticking of the chromium or damage on a substrate even if the defect is large. CONSTITUTION:Aluminum piece 8 is stuck to the isolated chromium defect 6 on a mask and this mask is immersed in sulfuric acid. The aluminum piece 8 elutes in this sulfuric acid in the form of ions. The naturally oxidized film on the surface of the chromium defect in contact with the aluminum piece 8 is reduced to chromium 9 by the electrons made to remain at this time, thereby the film is eventually dissolved into the sulfuric acid. Further, this chromium is eluted into a sulfuric acid tank, thereby, the electrons are made to remain and the reduction of the naturally oxidized film of the chromium is successively spread. All the chromium defects are thus dissolved into the sulfuric acid and the chromium defects are corrected.

Title: Memory control circuit
Inventor: NISHIBE SHINJI
IPC: G06F13/42
Filed: 1983-03-22
Abstract: PURPOSE:To vary a memory operation time without changing the hardware constitution by setting preliminarily numeric information, which corresponds to the speed of a used memory element, in a register. CONSTITUTION:Numeric information NR is set to a register 12 by an initializing microprogram. During the memory operation, a counter 16 performs the counting-up operation synchronously with a basic clock CLK. Contents of the counter 16 are cleared at a system initialization time. When the count value of the counter 16 reaches the value of numeric information, a comparator 18 detects the coincidence to output a logical-''1'' coincidence detection signal. An AND gate AND20 outputs the basic clock CLK to an OR gate OR22 during the memory operation as it is only when the coincidence detection signal is logical ''1''. As the result, the OR22 outputs a memory operation completion signal ME.

Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To reduce the scale of a circuit detecting the quantity of motion from 1st and 2nd field image data forming frames and attain a high operation speed. SOLUTION: A difference absolute value calculation device 3 calculates a difference absolute value for each picture element between 1st field image data from a field memory 2 and 2nd field image data and a comparator 4 compares the difference absolute value with a 1st threshold level Th1 and a total sum calculation device 5 obtains the total sum of the comparison outputs. A comparator 6 compares the obtained total sum with a 2nd threshold level TH2 to discriminate the quantity of motion of a frame image. Thus, number of adder circuits and shift registers being components of the total sum calculation device 5 is reduced to reduce the circuit scale.

Title: Digital arithmetic unit
Inventor: TSUDA KATSUHISA
IPC: G06F1/30
Filed: 1989-02-28
Abstract: PURPOSE:To ensure a normal writing operation despite the absence of a power holding capacitor by preparing an EEPROM and writing the decided data out of the arithmetic result together with the flag data. CONSTITUTION:Plural process signals undergo the A/D conversion and a microprocessor of a digital arithmetic part 2 applies the arithmetic operations to these digital signals. These arithmetic results are stored in a memory RAM 3. A read/write control part 4 writes the decided data into the blocks B1 and B2 of an EEPROM 1 and controls them out of those arithmetic results. In this case, the flag data is also written to show whether the data is normally written or not. Thus the data written into the blocks B1 or B2 is correctly held despite the occurrence of an unexpected trouble. As a result, the data can be correctly written into the EEPROM 1 even with no use of a power holding capacitor.

Title: Method for burning ceramic product
Inventor: SUGIYAMA TAKAYUKI
IPC: F27D5/00
Filed: 1990-02-28
Abstract: PURPOSE:To carry out homogeneous burning and prevent ceramic products to be burned from deforming and cracks from occurring, etc., due to spalling by burning the products to be burned in a state buried in innumerable ceramic hollow granules in burning the ceramic products. CONSTITUTION:Products (ceramic products) 1 to be burned (e.g. ceramic pipe) are contained in a container 2 made of a refractory and innumerable ceramic hollow granules 3 (e.g. alumina bubbles) are filled in the container 2 so as to bury the products 1 to be burned. In this state, the container 2 made of the refractory is then carried into a furnace and burned. Thereby, the products 1 to be burned are softened at high temperatures during burning. Since the whole peripheries thereof are surrounded with groups of the ceramic granules 3 so as to be tightened from the surroundings therewith, regular shape properties are retained without causing strain due to their own weight. Although the products 1 to be burned are covered with the ceramic granules 3 in the form of layers, the ceramic granules 3 are hollow and lightweight. As a result, strain, deformation, etc., of the heat softened products 1 to be burned can be prevented.
