IPC: G06K9/34
Filed: 1989-04-17
Abstract: PURPOSE:To raise precision, and to accelerate speed by dividing a document picture into plural areas in the direction of a line, and segmenting the line by deciding whether it is the line or a space between the lines according to projection in a line direction within check width wider than it, and segmenting a character by deciding a range according to the projection in the direction perpendicular to the direction of the line. CONSTITUTION:The line is segmented by dividing the document picture into plural areas in the direction of the line by a control part 101, and the line is segmented by the control part 106 by deciding whether the area is the line or the space not by checking horizontal projection for the line segmentation in respect of the range of each divided area but by checking it in respect of the range of the check width which is wider than each divided area and in which the adjoining divided are overlaps partially each other. Then, the character is segmented by a character segmenting part 111 by determining the segmenting range of the character according to the projection in the direction perpendicular to the direction of the segmented line. Thus, segmenting processing can be executed highly precisely and at high speed.

Abstract: PURPOSE: To prevent water, etc., from infiltrating into a heat-insulating space part by disposing, in an outer case, a deaeration member for discharging high-pressure air through a through-hole in the case where an air pressure in the heat-insulating space part surrounded by both the outer case and an inner case becomes higher as compared with an ambient air pressure. CONSTITUTION: A hot-keeping/cold-keeping container comprises an outer case 1 and an inner case 3 housed in the outer case 1 with a heat-insulating material therebetween and forms a heat-insulating space part 5 surrounded by both the outer case 1 and the inner case 3.

Title: Shaft seal structure of refrigerator compressor
Inventor: FUJIWARA YASUSHI
IPC: F16J15/34
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To effectively prevent a leakage of carbon dioxide refrigerant gas out of the shaft seal part of a refrigerator compressor, which is caused by changing the refrigerant gas of a refrigerating cycle to the carbon dioxide from fluorocarbon. SOLUTION: A first mechanical seal 3 and a second mechanical seal 4 are installed in a space between an inboard space A and an outboard space B of a refrigerator compressor, and CO2 insoluble or slightly soluble mineral lubricating oil L is filled up in an intermediate chamber C lying between both these seals 3 and 4.  Since a part of high pressure CO2 refrigerant gas in the inboard space A is melted in refrigerating machine oil, it is slightly leaked into the intermediate chamber C through the refrigerating machine oil being interposed as a lubricating oil film in a sealed sliding surface 30 of the first mechanical seal 3, but a sealed sliding surface 40 of the second mechanical seal 4 sealing a space between the intermediate chamber C and the outboard space B is lubricated by the mineral lubricating oil L, so that the CO2 refrigerant gas in the intermediate chamber C is checked of its more leakage into the side of the outboard space B. After pressure in the intermediate chamber C is approximately balanced with that in the inboard space A by the leakage of the CO2 refrigerant gas, the leakage of the gas into the intermediate chamber C from the first mechanical seal 3 is also checked as well.

Ferromagnetic oxide magnetic substances 16 and 17 respectively constitute the main parts of the first and second auxiliary magnetic poles. Thus the perpendicular magnetic recording/reproducing head at the high magnetic recording/reproducing efficiency can be obtained.

Title: Method and apparatus for confirmation of life or death of cable
Inventor: HASHIZUME TOSHINARI
IPC: G01R1/067
Filed: 1992-04-17
Abstract: PURPOSE:To safely confirm whether a cable is live by a method wherein, while a pressing-into rod in which the circumference of a conductive part has been covered with an insulator is being pressed into toward the center of the cable, the potential of the conductive part is measured. CONSTITUTION:A pressing-into rod 1 is constituted of an insulating rod body in which a conductive part has been buried in the central part; its tip part is worked to be sharp. A cable 14 as an object to be confirmed is sandwiched between, and held by, sandwiching and holding members 6; a fluid pressure is supplied gradually to a pressing-into cylinder 3 from a pressure pump 10. Then, a piston 4 is advanced; the pressing-into rod 1 is pressed into the central direction of the cable 14. As the pressing- into operation of the pressing-into rod 1 progresses, an induction voltage is generated at the conductive part in the pressing-into rod 1. A potential measuring instrument 8 measures its potential. When the potential of the induction voltage exceeds a prescribed potential, a judgment device 12 judges it as a live-wire state. An alarm is issued from an alarm part 13; the pump 10 is stopped and the pressing-into operation is stopped. Even when the cable is in the live-wire state, a ground fault is not caused because the pressing-into rod 1 is insulating. A live or dead state can be confirmed safely.
