Title: Output signal correction device for image sensor
Inventor: CHIYOMA HITOSHI
IPC: H04N1/40
Filed: 1992-06-17
Abstract: PURPOSE:To obtain the output signal correction device for an image sensor with high accuracy in which the processing is performed at a high speed and its storage capacity is saved. CONSTITUTION:A white reference level original is read as the initializing, an output signal of an image sensor 1 in this case is separated into an image signal component and a dark signal component by a sample-and-hold circuit 2, a difference signal between both the separated signals is obtained by a differential amplifier circuit 3, the obtained difference signal is digitized by an A/D converter 4 and stored in a memory 5 as white level reference data. In the case of reading of an actual original, an output signal of the image sensor 1 is imparted similarly to the sample-and-hold circuit 2 and the differential amplifier circuit 3, from which a dark signal component is normalized and digitized by the A/D converter 4 and the result is inputted to a divider 6. The divider 6 implements division by letting an output of the A/D converter 4 be a divided and by letting the white level reference data stored in the memory 5 be a divisor to obtain the digitized output signal of the image sensor 1 subject to correction at every pixel.

Title: Device to make particles into flow
Inventor: KANETANI TOSHINORI
IPC: B01F33/40
Filed: 1977-12-29
Abstract: PURPOSE:By the action of a stirrer placed in a flowing layer, scattering of fine particles due to the occurrence of air bubbles or an air layer is prevented, and a flowing layer is maintained uniform and stable in a device to make particles into a flow. CONSTITUTION:An air flow ejected from porous plate 2 blows up particles ejected from port 6, and forms a flow layer inside tank 1. Since a spiral air flow with higher speed compared with the air flow in the surroundings is generated near stirrer 10, the air flow is stirred, and air bubbles and air layers are crushed at the initial stage of generation and hence they do not grow large. Consequently, a stable and uniform air layer is maintained. When the particles are manure, glass peices and other objects contained in it settle down in the lower part of the flow layer due to the differences of relative gravities. Refined manure particles float and overflow from port 7 and are taken out. Other objects are discharged from discharge port 8 from time to time. Further, by changing the height of stirrer, the height of the flow layer can be adjusted.

Title: Superconductor thin-film board
Inventor: YAMAWAKI HIDEKI
IPC: C01G1/00
Filed: 1992-06-17
Abstract: PURPOSE:To lessen the influence of scattered light by a board incident from the rear of a photoresist film, by using a composite layer board for suppressing scattered ultraviolet light from a transparent board for resist exposing. CONSTITUTION:A Bi2Sv2CuOx normal conductor layer 2 and a Bi2Sr2Cu2Ox superconductor 3 are deposited on a plane (100) MgO board 1 by halide CVD, for example. And plane (001) MgO has a lattice constant approximate to those of the normal conductor layer 2 and a superconductor thin-film 3. And the Bi2Sr2CuOx normal conductor layer 2 absorbs ultraviolet rays emitted from the openings of a glass mask 5 effectively, in case of the patterning of a photoresist film 4. Accordingly, it becomes possible to make the patterning precision higher, improve the performance of the superconducting element, and increase reproducibility, since the light-absorbing oxide normal conductor layer 2 absorbs scattered light too which has come back after being reflected by the rear of the MgO single crystal board 1 in groove 6 regions.

Title: Ink jet printing head
Inventor: SHIODA TOYOJI
IPC: B41J2/045
Filed: 1986-07-04
Abstract: PURPOSE:To increase the quantity of ink droplets jetted, without lowering a driving frequency, by partitioning a nozzle corresponding to a pressure chamber by partitioning means into a plurality of nozzles, thereby forming a nozzle group. CONSTITUTION:A first nozzle plate 4-1 made to be as thin as about 40mum so as to set the cross-sectional area of a nozzle 10 to 1/3 and cut out only at the part of the nozzle 10 is laminated with a first partition plate 6-1 made to be as further thin as about 20mum, and a second nozzle plate 4-2, a second partition plate 6-2 and a third nozzle plate 4-3 are similarly laminated with each other to provide a nozzle group consisting of a first nozzle 10-1, a second nozzle 10-2 and a third nozzle 10-3 each of which has a cross-sectional area of 120mumX40mum. Since the cross-sectional area of each of the nozzle is smaller than that in a conventional design though the total cross-sectional area of the nozzle group is the same as that in the conventional design, the radius of curvature of a meniscus is reduced, and a force directed to the exterior is enlarged. Accordingly, deterioration of driving characteristics due to an increase in the quantity of an ink being jetted can be improved.

Title: Abnormality detecting circuit for microprocessor device
Inventor: MIWA TATSUYA
IPC: G06F12/16
Filed: 1990-06-16
Abstract: PURPOSE:To instantaneously and accurately detect the abnormality of a microprocessor device by comparing the parity of the data read out as a program with the parity corresponding to the program data calculated and stored previously. CONSTITUTION:The parity of the data read out as a program is compared with the parity corresponding to the program data calculated and stored previously. That is, a comparator 5 compares the parity data 14 received from a parity calculation circuit 4 with the parity data 14 received from a parity data ROM 3. Then the comparator 5 recognizes the working abnormality of a microprocessor device when no coincidence is secured between both data 13 and 14 and outputs an alarm signal 15. Thus it is possible to instantaneously detect two types of working abnormality, i.e., a reading error occurring during an access given to a program area and the reading of the program data caused by a malfunction to a non-program ROM area respectively.

Title: Continuous voice recognition system
Inventor: ICHIKAWA AKIRA
IPC: G10L15/10
Filed: 1980-11-12
Abstract: This speech signal recognition system compares the two-dimensionals pattern (time sequence of feature vectors) of an unknown signal to prestored standard references patterns for recognition, thus forming a corresponding two-dimensional comparison pattern of points of elemental Hamming distance differences. The sum of the pattern point distances is the similarity measure. To improve accuracy, partial patterns are selected (or "masked") and tested sequentially, and the point values weighted relative to their location within the mask. The mask may be rectangular or oblique.

Title: Design evaluation system
Inventor: YAMAGUCHI EIICHI
IPC: G06F19/00
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To support design improvement of a product by outputting design evaluation information which is information that shows the cause with which the result of production simulation does not satisfy a production plan and is related to a product design. SOLUTION: A database interface 4 extracts necessary information from each database 1 to 3 of design information, production information and sales information, generates conditions, etc., that are needed for simulation and supplies them to a virtual factory simulator 5. The simulator 5 virtually generates a product model based on an inputted condition and also carries out production simulation about the virtual product model. A simulation result outputting part 6 shows design evaluation information on a display from a production simulation result. In such cases, when production demand is not satisfied, information about the cause is outputted. Because of this, a product designer accurately performs design improvement by looking at outputted and displayed design evaluation information.

Filed: 1989-06-22
Abstract: PURPOSE:To miniaturize and lighten a three-way valve, reduce its noise and enhance its profitability by switching the switching direction of a delivery port by means of electricity transmission to a switching means made of an electrothermal shape memory alloy and extended with one end fixed to a valve and the other end to a frame. CONSTITUTION:A linear material 8 made of an electrothermal shape memory alloy is constantly held in a low temperature relaxed state and is stretched and deformed more than its basic form by the resilient force of a spring 6, and a valve 5 is energized leftward and a rubber 11 provided at the end of the valve 5 is seated on the inner end portion of a delivery port 3 so that the delivery port 3 is closed. An auxiliary flow passage 10 and a flow passage 13 are communicated with each other so that a delivery port 4 is opened. The linear material 8 is caused to generate heat by means of electricity transmission and is deformed and recovers to its contracted form at a predetermined temperature. The valve body 5 shifts to the delivery port 4 side and the delivery port 4 is closed, while the delivery port 3 is opened. The three-way valve is thus miniaturized and its working noise, vibration by impact and power consumption are reduced.
