The invention discloses a method for plugging a leaking point of a flange face and a sealing gasket of high-pressure equipment. The method includes the following steps: disposing a glue injection bolt in a bolt hole, and enabling an outlet of an L-shaped hole to be positioned at the leaking point of the flange face and the sealing gasket, wherein the glue injection bolt is provided with the L-shaped hole formed downwards from the head of the glue injection bolt along the axial direction, and the L-shaped hole is a glue injection passage; injecting a sealing agent through the glue injection passage to plug the leaking point; screwing a sealing bolt into the L-shaped hole to seal the glue injection bolt, wherein the sealing bolt is matched with the L-shaped hole. Correspondingly, the invention further discloses a device used in the method. The device comprises the glue injection bolt and the sealing bolt. The glue injection bolt is provided with the L-shaped hole downwards formed from the head of the glue injection bolt along the axial direction, an outlet end of the L-shaped hole is communicated with the outside, and outer diameter of the sealing bolt is matched with inner diameter of the L-shaped hole. The method and the device have the advantages that the leaking point, positioned on the flange face and the sealing gasket, of the high-pressure equipment can be plugged quickly, conveniently and effectively.

PURPOSE: To effectively prevent an electronic slip from being falsified by a malicious operator by reading a symbol on the slip, thereafter comparing management numbers, and applying an image processing only to the slip the management number of which is not recorded on a file CONSTITUTION: The slip 1 formed by the customer is read by an image reading part 2a and the management number is printed This image processed electronic slip is registered in the temporary file 3b of a processor 3 together with the management number In the processor 3, the registered management number is compared with the management number registered in an image file 3c in an management number comparison circuit 3a, when the same number is not present in the file 3c, the image processed electronic slip is delivered to a terminal equipment 4 and deleted from the file 3b In the equipment 4, associated and required information is recorded supplementarily from an input part 4c according to the image processed electronic slip displayed on an image display part 4b and registered in the file 3c together with the image processed electronic slip Accordingly, the processed image electronic slip reenters and is not changed to the image processed electronic slip COPYRIGHT: (C)1987,JPO&Japio

Indelible system for electronic slip

PURPOSE:To instantaneously input a character rejected due to a non-reading by correcting and inputting the recognition result of an image OCR mechanism by a hand written data input means. CONSTITUTION:Image OCR data read and recognized from a source slip by the image OCR mechanism 2 is displayed on an image display mechanism 3. In this case the non-read part is displayed as a '?' mark. To the non-read part displayed on the image display mechanism 3, corresponding data is inputted by hand writing the corrected character of the rejected character on the hand writing input mechanism 4 by referring to the source slip. The hand written data is displayed on a position adjacent to the non-read part of the image display mechanism 3. The OCR recognized and completed image OCR data is stored in an OCR data file 5.
