Abstract: PURPOSE:To obtain the recognition device, accuracy thereof is high, for the position of an IC pad by executing oblique illumination and detecting the rectangularly crossed sections of a plurality of bright lines in a picture as edge corners by using an L-shaped sensor. CONSTITUTION:A pickup information of which the ridgeline section of a semiconductor chip is displayed as the bright lines 9 generated by reflection through oblique illumination is made contain into a frame memory, and the picture information is scanned Y in the lateral direction in succession from the upper direction by a cut-out window KM, thus detecting the presence of the edge corner, which must be checked previously, within the range. Distances alpha, beta up to the center of a detecting window from a chip- corner previously inputted while using a chip-corner C1 as a base station and the quantities of displacement DELTAalpha, DELTAbeta by the inclination of the chip are obtained, and the detecting window 19, which has the center where separate by alpha-DELTAalpha in the X direction from the chip-corner C1 and by beta+DELTAbeta in the Y direction and has the sides of gamma and delta, is cut out. A pad-pattern in the detecting window 19 is recognized in such a manner that the binary coded signal is projected to an X axis and a Y axis and the width of the pattern and the center are acquired from the number of the signal bits.

Abstract: PURPOSE:To produce a large-sized ferrite single crystal, economically, in high yield, by contacting a single crystal ferrite to a surface of a polycrystalline ferrite, and heating the product while applying a means to suppress the discontinuous grain growth at the back surface of the polycrystalline ferrite. CONSTITUTION:A polycrystalline ferrite 2 prepared from iron oxide having spinel structure or having the history of spinel structure, and a single crystal ferrite 1 having the same composition as above, are polished to mirror surface. The polished faces are made to contact with each other interposing an organic acid or an inorganic acid therebetween, and a means 3 to suppress the discontinuous grain growth is applied to at least the back surface of the polycrystalline ferrite 2. The assembly is heated at about 1,300-1,350 deg.C. The crystal of the single crystal ferrite 1 is grown toward the polycrystalline ferrite 2, and the growth of the crystal having undesirable crystal direction can be suppressed by this process to obtain a large-sized ferrite single crystal 4. The above means to suppress the discontinuous grain growth is e.g. a dummy core of ferrite having low rate of crystal growth or a skin membrane formed by heating the polycrystalline ferrite.

Filed: 1986-03-13
Abstract: PURPOSE:To detect an inputted timing diagram, even if it is entered somewhat roughly, if it is within a section, by settling the section where the timing diagram is entered by means of a section settling means of a timing diagram reader. CONSTITUTION:An image which is read temporarily by a CCD and is stored in a storage part 5 has unit characters extracted by measuring the size of an isolated graphic form in a character image separating part 7. Thereafter, reference symbols written at four corners of an input form are retrieved by a reference symbol part 9, and symbol positions P1-P4 are obtained with coordinate values. Based on positions P1-P4, a virtual rectangle calculating part 11 calculates coordinates of a virtual rectangle t(mn) after obtaining the inclination and the degree of expansion/reduction of the image so that M-step N-signal description is possible. An image feature detecting pat 15 generates a histogram of the number of black picture elements in X and Y-axis directions based on the position of the virtual rectangle and performs raster scanning in the Y-axis direction to obtain the Y coordinate where the first black image element exists. The classification to which the timing diagram belongs to is decided 17 based on features of the picture.

Abstract: PURPOSE:To decrease the inclusion of high b.p. impurities such as lead and iron considerably and to recover zinc of high grade by condensing part of zinc vapor in the flow passage of a downcomer and flowing the same down into a well part. CONSTITUTION:The vapor of Zn reduced and formed in a vertical retort is fed through a downcomer 16 into a condenser 17, and is subjected to shock cool by the zinc splash in a sump, whereby Zn is condensed and is recovered as a base metal. During this time, part of the vapor of Zn is condensed with a cooling body 20 suspended in the downcomer 1. The gaseous flow is brought into collision against the body 20 to change flow so as to flow into the condenser 17. The fine particle dust and Pb drop contained in the gaseous flow are adsorbed and captured on the molten zinc drop condensed on the body 20 and are separated from the gaseous flow. Such molten zinc is flowed down into the well 21 in the lower part of the downcomer 16 from which the zinc is discharged continuously into a depositing furnace. As a result, only the zinc vapor of high purity is fed into the condenser 17, and the base metal having high zinc grade is recovered.

Title: Differential self-exciting bridge type current sensor
Inventor: TAKEUCHI SHINJIROU
IPC: G01R15/18
Filed: 1984-03-21
Abstract: PURPOSE:To make it possible to detect an input current with high sensitivity, by negating uniform parallel magnetic field components applied to two magnetic cores by diffential connection and using the operation amplifier in a bridge as a voltage control switching element. CONSTITUTION:Magnetic cores 4a, 4b are inserted into the central space part of a glass tube around which exciting winding 2 is wound in reversed polarity. Now, when the output of an operation amplifier OP1 is changed over to positive saturation DC voltage, the magnetic flux density level in a united magnetic core is rapidly returned to the magnetic flux density level prescribed by input current to be measure inputted to terminals 50a, 50b. As said magnetic flux density level approaches positive max. magnetic flux density, the impedance Z2 of the exciting winding 2 is lowered and, when Z2<R10 is formed, negative saturation DC voltage is generated in the output of the operation amplifier OP1. By this mechanism, the saturation DC voltage of the operation amplifier OP1 is automatically changed over every time when the united magnetic core reaches positive and negative max. magnetic flux density and this output is integrated by an operation amplifier OP2 and the direction and intensity of the input current are displayed by an indicator 19.
