Title: Preprocessor
Inventor: TANABE YOSHIHISA
IPC: G06K9/36
Filed: 1984-03-19
Abstract: PURPOSE:To form a binary-coded pattern signal close to a psychological pattern image by constituting a preprocessor of a feature extracting circuit, a matching circuit, a binary-coding circuit, and a reference wave pattern changing means. CONSTITUTION:An original pattern I is converted into an electric signal waveform by a photoelectric converting circuit 10 and the feature of the waveform is extracted by the feature extracting circuit 11. The waveform is matched with a reference waveform pattern in a dictionary memory 13 by the matching circuit 12 and a waveform pattern determined on the basis of the matched result of the matching circuit 12 is converted into a binary-coded signal BP by the binary coding circuit 14 on the basis of a previously set up slice level. The binary signal BP is recognized by a recognizing circuit 15, and when the binary signal BP is rejected, the reference pattern in the dictionary memory 13 is changed. Thus, a waveform pattern close to a psychological pattern image can be obtained on the basis of the matching processing between the feature waveform pattern of the original pattern and the previously prepared reference waveform pattern.

Title: Electro-chromic display element
Inventor: WADA SHUICHI
IPC: G02F1/17
Filed: 1988-03-07
Abstract: PURPOSE:To improve the reaction efficiency of coloring/decoloring of the title display element and to improve the display characteristic and to prolong the life of the element by allowing V to hold a metallic porous body a conductive paste containing a counter-electrode active substance by counter-electrode substance layer of the element. CONSTITUTION:A facing electrodes 8 is constituted of a facing electrode 9 and counter-electrode substance layer 10 formed on the electrode 9. The layer 10 is formed by thinly applying a conductive paste 10b containing a counter- electrode active substance to a metallic porous body 10a. Therefore, the electric resistance on the facing electrode 8 side is reduced, since the surface area on the facing electrode 8 side which contributes to the coloring and decoloring reactions becomes larger and, moreover, the metallic porous body 10a has excellent conductivity. Accordingly, the reaction efficiency to the coloring/decoloring is improved and high response speed is achieved even when the applied voltage is low. In addition, the coloring contrast becomes larger and the life of this display device can be prolonged.

Title: Scroll compressor
Inventor: MIYAKE SHIGEJI
IPC: F04C18/02
Filed: 1990-03-07
Abstract: PURPOSE:To prevent a poor compression and increase operating pressure range by connecting a back pressure chamber with a discharge pressure part through a passage having a solenoid valve and a resistance means interposed therein, and providing a control means for increasing the pressure of the back pressure chamber in proportion to discharge pressure. CONSTITUTION:A back pressure chamber 17 is connected to a discharge pressure part 20 through a bypass pipe 27 in which a solenoid valve 26 and a resistance means 28 are interposed. When the actual pressure calculated by an integrated circuit 24 is lower than an optimum pressure by a certain fixed level or more, the integrated circuit 24 opens the solenoid valve 26 to communicate a discharge pipe 21 to the back pressure chamber 17. Thus, the pressure in the back pressure chamber 17 can be controlled to prevent a poor compression due to the poor adhesion of a turning scroll 6 with a fixed scroll 5 because of pressure lack in the back chamber 17, and operating range can be increased.

Filed: 1990-03-05
Abstract: PURPOSE:To improve the processing capability of a grain receiving and measuring device by providing a constitution wherein the grain in a storing tank in which the grain is supplied at the last time among a plurality of storing tanks is fed into a measuring device at first. CONSTITUTION:After a producer's code and the Nos. of storing tanks T1 and T2 are collated, corresponding tank shutters S3 and S4 are opened. Grain is fed into a storing tank 13 with the full amount being monitored. When the same kind of the grain is stored in two tanks T1 and T2, the shutter S3 or S4 corresponding to the tank T1 or T2 in which the grain is stored at the last time is opened at first. After the tank T1 or T2 is emptied, the shutters S3 and S4 corresponding to the other tank T1 or T2 are opened. In this way, the time until the tanks become vacant can be shortened. As a result, the feeding of grain which is conveyed into hoppers H1 and H2 and fed into the tanks T1 and T2 for the next measurement can be started earlier.

Filed: 1992-02-05
Abstract: PURPOSE:To obtain the galvanized steel plate having excellent blackening resistance by forming an electrogalvanizing layer limited in lead content on the surface of the steel plate. CONSTITUTION:The electrogalvanizing layer is formed on at least one surface of the steel plate. The lead content in the electrogalvanizing layer of this electrogalvanized steel plate is confined to <=10ppm. The lead content in an electrogalvanizing bath is required to be decreased and the plating is required to be executed under the conditions under which the lead hardly precipitates in the electrogalvanizing layer in order to attain the <=10ppm lead content. A chromate film is preferably formed on the above-mentioned electrogalvanizing layer in the case of use without coating. As a result, the electrogalvanized steel plate which does not generate the blackening in spite of production under any conditions and has the excellent blackening resistance is obtd.

Abstract: PURPOSE:To set a threshold level by which an object is clearly separated from its background by obtaining a density level that maximizes an inter-class dispersion within a prescribed density level range when density distribution is divided into two classes and setting the density level as a threshold level used to separate the object from the background. CONSTITUTION:A cast iron piece 2 being an object is picked up by a CCD camera 18, and its resulting image is given to an A/D converter section 22, and its output is stored tentatively in a picture memory 24. A character segmentation section 26 specifies a position of each character based on the stored picture signal and a density distribution measurement circuit 28 measures the density distribution of each specified character within a range of a circumscribed rectangle shape. Then, a threshold level calculation circuit 32 calculates a threshold level used to separate the character from its background by using inter-class dispersion. In this calculation, the density level maximizing the inter-class dispersion is obtained within a prescribed density level range stored in a 1st picture memory 34 and a binarization processing section 36 realizes a stable binary image.
