Title: Character reader
Inventor: OKAWA MASAHIRO
IPC: G06K9/03
Filed: 1995-02-16
Abstract: PURPOSE: To exactly read a character overlapping a frame by providing a laterally long straight line detecting part with which a laterally long straight line continued in a prescribed length is detected, segmenting a character image in the area having overlapped the laterally long straight linen after the straight line was deleted, and reading character information in that area. CONSTITUTION: Concerning the area having a laterally long line segment, the lateral histogram of a character image is prepared and an image more than a reference is judged as the laterally long line segment. The presence/absence of the laterally long line segment is judged by processing 13 for laterally long straight line detection at a laterally long straight line detecting part 12. Then, the number of laterally long straight line is judged and when there are two laterally long straight lines in a valid range, those lines are judged as cancel lines but when there is one line, it is judged as a print guide frame. Then, the canceled lines are removed and the number of canceled digits is judged, and one space before the canceled character, the canceled character, for example four digits, and the space after the canceled character, is detected.  Then, the canceled area is outputted as reject and the laterally long straight line is removed. Next, character recognition is performed and the result is outputted.

A part of the light leaks to the optical fiber 12 via the connection section 14. The leaked light is inputted to a photodetector 31 of the measuring section 30 via an optical fiber cable 41 so that the optical intensity as measured.

Title: Exhausting device for mill
Inventor: TAKAHASHI YOSHITAKA
IPC: B01D46/02
Filed: 1992-02-14
Abstract: PURPOSE:To efficiently utilize crushing heat and to save maintenance cost by connecting a soundproof room and a dust collecting room with a crushing heat duct for supplying the crushing heat of a mill. CONSTITUTION:Since crushing heat in a mill 6 is radiated from the external surface of the mill 6, the temp. of air in the soundproof room 9 is raised by the crushing heat. Thus, a slight opening 33 is provided on the lower part of a soundproof wall 8 so that open air enters the soundproof room 9. Then, the crushing heat from the soundproof room 9 is supplied to a dust collector 15 by a crushing heat duct 32 to heat the exhaust air from ducts 16, 17 by the crushing heat from the crushing heat duct 32. Thereby the temp. of the filter cloth surface of the dust collector 15 is raised to the vaporization point of water or above to prevent the condensed water from being stuck on the filter cloth surface. Consequently, clogging of filter cloth due to coagulated sticking of water and collected dust is prevented.

Title: Method of recording defective region of disk medium
Inventor: GO KOKUZUI
IPC: G11B7/004
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To realize an efficient recording method of defective regions of a disk medium capable of recording a variable number of defective regions to one-defect list input. SOLUTION: This is a method of recording defective regions in a disk medium like a non-rewritable and rewritable optical disk where many successive defective regions may occur. In the medium, the addresses of defective regions are recorded in such a type of code as a run-length limit code. For example, in a main defect list of a defect management region of the optical disk, a group of consecutive region numbers is recorded using (N, L) format. N presents a starting region number of the group in consecutive regions, and L presents a length of the group of consecutive region numbers. Many defective regions can be recorded by this method. It becomes possible to manage defects of a disk medium of a high capacity without increasing defect management regions by this coding mode.

Title: Coder and decoder between frames
Inventor: IIJIMA MASAHIKO
IPC: H04N19/50
Filed: 1980-03-06
Abstract: PURPOSE:To enable to quickly make in agreement with the content of the frame memory of the transmitter/receiver, by adding the coding mode control circuit with the coder. CONSTITUTION:The coding mode control circuit 40 generates the coding stop signal in response to the refresh control information given to the input terminal 41 and it is given to the quantizing circuit 23. The circuit 23 responds to this signal to zero the output of the circuit 23. Thus, the content of the frame memory 13 is fixed to the video signal immediately before the coding stop. Further, the generating speed of the output information of the variable length coding circuit 31 is very less and the amount of information storage of the buffer memory 32 is gradually decreased. The circuit 40 supplies PCM TV signal to the coder 20 in the frame when the amount of information storage of the memory 32 is a given value or less. Thus, the content of the memory 13 is rewritten by using the local decoding signal obtained from the coder 20. On the other hand, in the decoder, when the refresh mode is detected from the coding mode signal at the variable length composite circuit 51, the content of the frame memory 72 is rewritten to the output of the decoder 60 in the frame.

Filed: 1989-02-10
Abstract: PURPOSE:To prevent a storage efficiency from lowering by forming a sample inlet and a solvent outlet in a cylindrical container main body and installing a solvent permeable separation membrane in either of them. CONSTITUTION:A solvent 5 in which a sample 6 is dissolved is led through a sample inlet and packed in a container main body 2 and then reaches a solvent permeable separation membrane 3. The whole of the sample 6 dissolved in the solvent 5 is captured. Meanwhile, the solvent 5 is permeated the solvent permeable separation membrane 3 and becomes reproduced solvent. Owing to the property of the separation membrane 3 which does not change the composition of the solvent 5 at all, the reproduced solvent 7 can be reused as a solvent 5. The sample is stored in the whole area surrounded with a sample inlet 1, the container main body 2, and the separation membrane 3 and the storage and transportation efficiency of the sample is improved.
