Abstract: PROBLEM TO BE SOLVED: To provide a plate material for building, by which while the connecting strength is held, the executability of sliding or the like at the time of connecting and fixing work or positional alignment or the like can be improved. SOLUTION: A male-like connecting part 12 of one edge in the cross direction of a siding material 10 formed by providing a filler 14 in the interior of an inverted gutter-like surface material 11 and covering the same with a back material is so constructed that a projecting part 12b of the central part in the direction of thickness of the siding material 10 and a nailing piece 12d of the lower end part are parallel to the surface material 11. A female-like connecting part 13 connected to the above part 12 is formed by a horizontal upper clamp part 12b and a lower clamp part 12d inclined downward to open, which are connected to each other by a substantially circular guiding recessed part 12c.  Thus, at the time of connection, inclination of the lower clamp part 13 is utilized to connect the parts 12, 13 with a gradient, and after connection, the fine adjustment can be facilitated by decrease in the contact area caused by the upper and lower clamp parts 13b, 13d.

Title: Wire bonding method and equipment
Inventor: KOMAKI YUJI
IPC: H01L21/60
Filed: 1991-10-31
Abstract: PURPOSE:To inspect at once a true wire loop which is not affected by adverse influence like vibration due to conveyance, by detecting a wire after bonding by using a camera for setting the bonding position coordinates. CONSTITUTION:A picture image wherein a semiconductor chip or leads are sensed is displayed on a monitor surface, and two bonding position coordinates P1, P2 are set. A capillary 4 is moved by controlling an XY driver 22 and a Z driver 24, and a wire 3 is connected between an electrode 1A and a lead 2. After bonding, a control equipment 30 determines the equation y=ax+k of a straight line which passes the two designated coordinate points P1 and P2 by calculation. The amount of curl wherein a wire loop is most bent is obtained by calculation and displayed on the monitor. Since the amount of curl of the wire loop can be inspected by a bonding equipment itself, adverse influence due to vibration during conveyance is eliminated, and true inspection results which are reliable can be obtained.

Abstract: PURPOSE:To simplify the drive mechanism of magnetization yoke and enhance the productivity by shortening the cycle time of a magnetization process. CONSTITUTION:On a turntable 1 rotated intermittently around a shaft 18, a plurality of anisotropic polar magnets (a), i.e., works are sequentially supplied from the work supply section 3, their poles are first aligned by a permanent magnet in a temporary magnetization section 4 and are temporarily magnetized.
