IPC: H01L21/60
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a work soldering method which can secure the electric continuity between a bump and a pad enough by lessening the quantity of flux used or further preferably by dispensing with the flux. SOLUTION: A highly hard projection 3 is projecting downward from the bump 2 of a work 1 provided with a bump.

Filed: 1986-10-15
Abstract: PURPOSE:To prevent a dishonest user from repeatedly using a remote office equipment by transmitting a specific command code from a center equipment to the remote office if a pass word inputted from the remote office is dishonest, and prohibiting the remote office from originating. CONSTITUTION:If the pass word of the user is a dishonest one which is not registered in a memory part 9 as the result of comparing and collating the pass word, a control part 8 transmits the specific command code from a modulating and demodulating part 10 to a MODEM 4 in the remote office and disconnects a line.

Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To make it easy to change display items on mutual correlative pictures by retrieving equipment which has properties corresponding to a specified management picture from a definition table and generating display information for displaying the management picture. SOLUTION: When a monitor picture display process is performed again, an arithmetic unit 4 specifies an equipment monitor picture as last display information, so equipment names by equipment kinds are specified in the definition table to generate display information. At this time, when lighting 3 is deleted from the definition table, 'lighting 1', 'lighting 2', and 'lemergency lamp' are left, and the display information for the monitor picture which consists of those equipment names is generated and outputted to a display device 3. When the monitor picture is switched in this state, equipment names are extracted by floors from the definition tables to generate display information for a monitor picture which consists of them. Thus, when the floor monitor picture or equipment monitor picture is displayed, corresponding equipment names are retrieved from the definition table to generate the monitor picture.

Abstract: PURPOSE:To attain a miniaturization, a lower price and a high definition by adjoining two pieces of point succession type line sensors and arranging them on a same chip with mutually shifting in the direction of main scanning by 1/2-times of arrangement pitch of a photoelectric transfer part. CONSTITUTION:Point succession type line sensors 21 and 22, of which color filter is repeatedly arranged in the order of R, G and B, are mutually shifted by 1/2-times against the arrangement direction (namely, main scanning direction) of photoelectric transfer parts 23 and 26. This color image pickup element is used as a scanner and moved in the direction (sub-scanning direction) orthogonal to the main scanning direction. Consequently, the same position of a still subject being image-picked-up by the point succession type line sensor 21 is continued and the image pickup is executed by the point succession type line sensor 22. Thus, reflected distortion is reduced and the miniaturization and the high definition can be inexpensively obtained.
