Title: Table recognizing device
Inventor: KAMIMURA YUJIRO
IPC: G06K9/36
Filed: 1993-05-28
Abstract: PURPOSE:To recognize table structure based upon a table picture inputted from a scanner. CONSTITUTION:A solid ruled line is extracted by connecting runs more than a fixed length out of runs in the two vertical and horizontal directions of a table picture inputted from a picture input part 21. Then, a black-white inverting cell candidate extracting part 24 extracts a part surrounded by width more than a threshold out of the extracted ruled line as a black-white inverting cell candidate. If the density of black picture elements in the extracted candidate is >50%, a black-white inverting cell determining part 25 determines the part as the black-white inverting cell. Picture elements in the determined cell are inverted by a picture element inverting part 26 to execute character recognition similarly to a normal cell. In the case of recognizing a table having a black- white inverted cell, the inverted cell is extracted at first and picture elements in the cell are inverted, so that table structure and internal characters can be more accurately recognized.

Title: Endoscope
Inventor: IKEDA KUNITOSHI
IPC: A61B1/00
Filed: 1995-05-26
Abstract: PURPOSE: To rarely damage the skin of a curve section and easily discover a pinhole on the skin of the curve section, if any, by providing an inside/outside communicating base near the connection section of an insertion section and an operation section. CONSTITUTION: A valve element 23 is moved to the rear side of a connection section of an insertion section 2 and an operation section 5, and an inside/outside communicating base 20 communicating the inside and outside of an endoscope is protruded. Since the inside/outside communicating base 20 is arranged below the grip section 5a of the operation section 5, it does not hinder the operation of the endoscope. When a light guide connector and the portion of a curve section 1 are held together to carry the endoscope, the skin of the curve section 1 is not damaged because the inside/outside communicating base 20 is not provided on the light guide connector.  Since the inside/outside communicating base 20 is located near the curve section 1, bubbles are easily released from a pinhole, if any, on the skin of the curve section 1 when air is fed into the endoscope from the inside/outside communicating base 20 for a pinhole check.

Title: Magnetic recording method and current driver for magnetic recording head used for method
Inventor: HERUMAN FUERIAA
IPC: G11B5/09
Filed: 1985-06-13
Abstract: PURPOSE:To reduce the heating of the recording head without altering the design of the head in common use by driving the head with a pulse periodically during the recording of one bit. CONSTITUTION:The recording head consists of two magnetic poles 10 and 12 across a gap, and the magnetic poles 10 and 12 magnetize a coating 14 to either of the two polarities corresponding to the direction of a supplied current. Assuming that a tape and its coating 14 are stationary at specific time, the magnetic poles 10 and 12 form bubble-shape magnetic saturation areas 16 in the coating. The bubbles extend laterally, so they overlap one another to form a continuous magnetized area of bubbles 20, 22, and 24. A next bubble 26 belongs to a bit to be recorded next and its polarity is opposite to that of the bubble 24 right before it.

Title: Anti-jamming socket
Inventor: FUJIMOTO KIYOJI
IPC: H01R33/76
Filed: 1992-05-20
Abstract: PURPOSE:To fully shield an IC socket so as to protect a high frequency signal component against jamming by a method wherein a shield plate is fixed onto the underside of an IC socket, and all the IC socket is covered through the intermediary of a gasket mounted on the circumference of the shield plate. CONSTITUTION:A shield plate 13 is fixed to the underside of a main mold 11, and a gasket 14 is mounted on the circumference of the shield plate 13. The shield plate 13 is kept at a ground potential coming into contact with an ground terminal 17 and prevented from coming into contact with a power supply terminal 16 and signal terminals. In result, an IC socket of this design can be lessened in ground impedance and shields jamming radio waves emitted from a digital IC main body. The gasket 14 is formed circular and elastic to produce no gap between the gasket 14 and a shield case when the main mold 11 is covered with the shield case, whereby a shielding operation can be fully carried out. Therefore, a digital IC socket can be more completely protected against, jamming at a lower cost.

Abstract: PURPOSE:To realize the simple and inexpensive binary counter. CONSTITUTION:When the up-count mode is commanded by an up/down control signal, a binary data stored in each of flip-flops 3a-3n is converted into 1's complement and then converted into 2's complement, and the binary data after the conversion of 2's complement is used to rewrite a storage data in each of the flip-flops 3a-3n. Thus, the binary data stored in each of the flip-flops 3a-3n is incremented by one. On the other hand, when the down-count mode is commanded by the up/down control signal, the binary data stored in each of flip-flops 3a-3n is converted into 2's complement and then converted into 1's complement, and the binary data after the conversion of 1's complement is used to rewrite the storage data in each of the flip-flops 3a-3n. Thus, the binary data stored in each of the flip-flops 3a-3n is decremented by one.

Title: Corrosion preventing method
Inventor: HAMADA IKUHISA
IPC: C23F15/00
Filed: 1979-10-05
Abstract: PURPOSE:To perform corrosion preventing treatment enabling easy detection of defects by periodic inspection, etc. by covering a corrodible part of the inside of a container holding a corrosive material with a metal thin film lower than the container forming member in galvanic series. CONSTITUTION:The weld line of a container holding a corrosive material such as liq. ammonia is apt to undergo stress corrosion cracking, so the inside of the weld line part of about 120mm. width is covered with Zn, Al or other metal, especially Zn lower than a steel sheet as the container member in corrosion potential rank by spraying. Since the thickness of the covered layer is adjusted to 0.2-0.3mm., defects can be detected by magnetic powder flaw detection with accuracy equal to that of the case with no sprayed layer. Accordingly, it is not required to remove the sprayed layer in periodic inspection, etc., and high corrosion preventing effect can be attained.

When one of each color R, G, and B of the filter 9, for example the R-section, a xenon lamp 8, and the end section of a light guide, through which the light is inputted, are arranged in one line, a shaft encoder 11 generates a luminous trigger signal 102 and the xenon lamp 8 is excited to emit light for a fixed time. The light is condensed in the vicinity of the light inputting end of the light guide after it passes through the R-section of the filter 9 and becomes a red monochromatic light. The condensed light reaches a light transmitting section 2a of an original plate 2 and lights an original 1. The light reflected by or transmitted through the original 1 forms an image on a photoelectric reading element 5, and the scanning on the image is started by a scan trigger signal 101, and thus, all bits are scanned. This procedure is performed in the same way on the next G and B sections.
