Abstract: PURPOSE:To enable the tentative fixing of a package to an insulating board by a method wherein heating pads are provided on the insulating board, on which connection pads joined to the solder bumps of the package are arranged, so as to be located outside the outer shape of the package, and the heating pads and the connection pads are connected together with heat transfer patterns provided with a solder dam on their surfaces. CONSTITUTION:A printed circuit board is formed in such a structure that connection pads 3-1 are formed at positions in matrix on the primary face of an insulating board 2 so as to be opposed to the solder bumps of a package, heating pads 14 are provided close to the connection pads 3-1, for instance, located at the four corners of foot patterns 3, and the heating pads 14 and the connection pads 3-1 tentatively fixed to the solder bumps are connected together through a heat transfer pattern 15 which is excellent in thermal conductivity and provided with a solder dam that prevents molten solder on the connection pad 3-1 from flowing to the heating pad 14. When the heating pads 14 are heated as making the connection pads the solder bumps 1-1 bear against the connection pads 3-1, the connection pads 3-1 rise in temperature by the heat transfer pattern 15 and the solder bumps 1-1 which bear against the connection pads 3-1 are fused and they are joined together. At this point, self- alignment is made and the relative position of a connection pad to a solder pad is corrected and they are tentatively fixed together.

The relative position of the connection pads 2-2a to the solder bumps 1-1 is corrected through a self-alignment effort induced by molted solder and they are tentatively fixed. The reflective mirror 13 is removed, and all the solder bumps 1-1 are made to reflow in a vapor solder bath, and thus the package 1 is mounted.

Title: Method for supervising plant status
Inventor: YAMAHATA NOBORU
IPC: G05B23/02
Filed: 1982-09-07
Abstract: PURPOSE:To monitor easily a plant by executing data processing only when the status of a plant signal is changed. CONSTITUTION:Plural plant apparatus and detectors are divided into related two groups and respective signal lines are connected to a data way 8 through process I/O devices 41, 42 connected correspondingly to the groups. When detecting the change of a plant signal, a data processor 7 forms a flag. The variation of signal state is detected in an analog signal when the signal is transferred to a different level area and in a digital signal when the level is changed from ''H'' to ''L''. The data processor 7 checks the state of a group in which a flag is formed with a prescribed cycle in detail and displays the state. Since the processing is executed only when necessary, the data processor 7 is prevented from loads.

Abstract: PURPOSE:To prevent a developer from a developing device on an undriven side from sticking on a photosensitive drum without rotating a magnet roller at every time by putting a developing device on a selected driven side closer to an image carrier and moving the developing device on the undriven side away from the image carrier. CONSTITUTION:The 2nd developing device 7 moves away from the photosensitive drum 4 and an interlocking cam 77 further rotates after the photosensitive drum 4 rotates by a specific angle, so that a projection 82 moves to the arrangement part of a rotary roller 87. The projection 82 presses the rotary roller 87 and then the developing roller 31 of the 1st developing device 6 comes close to the photosensitive drum 4 and faces it, so that development is carried out by a magnetic brush B. Further, when the 2nd developing device 7 is selected and switched from the driving state of the 1st developing device 6, the 2nd developing device 7 is arranged behind the 1st developing device 6 in the rotating direction of the photosenstive drum 4, so even if toner Da from the 1st developing device 7 sticks on the photosensitive drum 4 unnecessarily, it is never mixed with the toner Da in the 2nd developing device and the photosensitive drum 4 need not be rotated.

Title: Wire saw
Inventor: MATSUBARA MASA
IPC: B23D61/18
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To remove a fear of leading from break of a thin element wire to rapture of a wire without strong contact of a cylindrical sleeve of a bead with the wire by a method wherein an inner peripheral surface of the cylinderical sleeve is made a curved surface wherein an inner diameter continuously expands over from an inside of the cylindrical sleeve to its end part. SOLUTION: In a wire saw, an inner peripheral surface at both ends of a cylindrical sleeve 2 of a bead is curved surface 7 wherein an inner diameter continuously expands over from an inside of the cylindrical sleeve 2 to its end part. Therefore, when the wire saw is bent by a small radius of curvature such as when all circumference of a loop is short, at a corner of a cutting part, when a diameter of a driving pulley is small, etc., an end part of the cylindrical sleeve 2 of the bead is not locally pushed onto a wire 3. Then, stress received from the cylindrical sleeve 2 of the bead onto the wire 3 is dispersed thereby, and there is no fear that a thin element wire of the wire 3 is broken by contact with the end part of the cylindrical sleeve 2, and it leads to rapture of all the wire 3.
