Title: Dust-collecting method in structure for blast furnace
Inventor: IIZUKA MOTOHIKO
IPC: C21B7/14
Filed: 1978-03-16
Abstract: PURPOSE:To collect dust efficiently, by installing a partition which separates a blast furnace body from the front casting area, and by sucking dust-contg. air from the top of a structure constructed in the above-described front area, at the same time, by introducing air from outside to the blast furnace side. CONSTITUTION:A blast furnace body 1 is separated completely from a structure sonstructed in front area of the casting floor by partition wall 7'. Fresh air is introduced from outside by installing air pipe 12 at the blast furnace side of the partition wall 7' in order to dilute and remove toxic gas. In the front area, on the side opposite to the tap hole, is equipped a movable wall 8 in order to carry the dust by air flow, preventing shortcut air flow to the intake 11 of a dust collector. This constitution makes it possible to replace the conventional exhauster for the dust collector by an exhauster of smaller performance.

IPC: G06K9/34
Filed: 1985-02-19
Abstract: PURPOSE:To cope with character cut out of a handwritten drawing, a free format document, OCR paper without character frame etc. by enabling to separate character one by one even when characters are in contact with each other in the data. CONSTITUTION:In a character data processing device, the result of optical scanning of a drawing in which handwritten characters to be segmented are written is stored in a picture memory 1, and scanned data are loaded from inside of the picture memory 1. Character area of the loaded data is determined by a character area determining section 2. A character frame of the determined character area is extracted, and segmenting of individual character is made by a character frame extracting section 3. Segmenting of individual character is identified supposing that, for instance, the width W of a character is within 2/3h where (h) is the height of the character. That is, the characters adjoining but written off from each other are segmented on the basis of such width W.

Title: Manufacture of semiconductor device
Inventor: SHIMADA TAKASHI
IPC: H01L21/31
Filed: 1984-02-17
Abstract: PURPOSE:To reduce the difference in conversion from a mask by a method wherein an oxidation-resistant film is formed on an element-forming region after formation of a groove for the element isolation area on the surface of a semiconductor substrate, and the section other than the element-forming region in contact with the insulator filling the groove is partly removed; then, this section of removal is thermally oxidized. CONSTITUTION:Grooves 23 are formed in the element-forming region 22 of one main surface 21a of the substrate 21 where circuit elements are to be formed, and an SiO2 film 25 and an Si3N4 film 24 are formed over the entire surface. Next, doped oxide or SiO2 is formed as the insulator 26 so as to fill the groove 23, and further the surface is flattened by coating with a photo resist layer 27. Thereafter, etching is carried out from the surface of the resist layer 27 and stopped at the time of exposure of an oxidation-resistant mask 24. Then, the mask 24 and the film 25 on the main surface 21a in contact with the insulator 26 are removed, and etching is carried out to a depth not reaching the bottom of the groove 23. A thick SiO2 oxide layer 28 is formed by thermally oxidizing the section not coated with the mask 24. This manner enables the avoidance of generation of thermal strain due to the difference in the rate of thermal expansion from the Si substrate 21.

Title: Ceramic coil component
Inventor: BANDAI HARUFUMI
IPC: H01F27/29
Filed: 1990-02-08
Abstract: PURPOSE:To obtain a large inductance even with a small size and to realize a high Q by providing the following: a spirally arranged conductive part while its main face is in the direction parallel with the outer circumference face of a cylindrical ceramic sintered body; and outer electrodes which are formed at the cylindrical ceramic sintered body and which are connected electrically to the conductive part. CONSTITUTION:While the main face of a spiral conductive part 25 used to generate an inductance portion is in the direction parallel with the outer circumference face of a cylindrical ceramic sintered body 22, the conductive part is extended spirally from the side of one end 22a to the side of the other end 22b of the cylindrical ceramic body 22. The thickness direction of the spirally arranged conductive part 25 is perpendicular to the direction in which a magnetic flux generated by applying an electric current is extended. Consequently, since the spirally arranged conductive part 25 does not disturb the magnetic flux so much, the effective crosssectional area of a coil is increased effectively. Thereby, a ceramic coil component which is small-sized and whose inductance value is high can be realized without lowering a Q.

This information is an identification number of a mobile communication exchange 6 relating to a position registration area to which the mobile device 2 belongs and is, e.g. 40. This information is transmitted from the CC52 to the CC42. The CC42 controls a channel 41 based on this information before the connection control, connects the talkie device 45 and informs the position of the mobile device 2 to the telephone set 1.

Abstract: PURPOSE:To position wafers by a method wherein the first wafer is set correctly and with a digital information on a part thereof set standardized, a maximum point for correlative function with an arbitrary positional information for those of the second and after is calculated. CONSTITUTION:The first wafer is set correctly, scanned optically for one pellet, and a detection signal is digitalized to store. For those after the second on, the digitalized detection signal is detected after a rough positioning. A correlative function of the two is calculated as gammaalphabeta where discrepancies are alpha, beta at detection ranges l<=i<=M, l<=j<=N. alpha, beta are calculated so as to have gammaalphabeta at maximum, and from correction by alpha, beta, the wafers after the second one can be positioned correctly. For angle theta, a contrast is detected by a beam scanning in the direction of y at two spots several chips apart in the direction of x, a maximum value of correlative function for a periodic distribution is obtained, and the angle theta is thus sought. According to this method, a correct positioning is secured even if the difference between a dicing line and a character in the pellet is not clear.

Filed: 1990-02-09
Abstract: PURPOSE:To make improvement in durability and reliability by forming liners of non-woven fabrics contg. >=30wt.% polyester films and/or polyacrylonitrile fibers and incorporating polyurethane as a binder into a magnetic layer. CONSTITUTION:The non-woven fabrics contg. >=30wt.% polyester films and/or polyacrylonitrile fibers are used as the liners 4, 5. The non-woven fabrics have not only the effect of preventing elimination by bonding woven bodies but also can exhibit a sufficient cleaning effect by forming the woven bodies of the non-woven fabrics even with the same fibers alone. The quantity of these fibers is, therefore, essentially required to be >=30wt.% of the total weight of the non-woven fabrics. The polyurethane in which the negative functional group forms the intramolecular salt is used as the binder used for binding magnetic powder. The polyurethane has intrinsically wear resistance and has the high adhesive strength to other materials. The improvement in weatherability is thus made.
