Title: Solder supply plate
Inventor: TSUKADA KIYOTAKA
IPC: H01L21/52
Filed: 1990-04-18
Abstract: PURPOSE:To supply solder to a fine connection terminal of an electronic component or the like with high precision but with no short circuits of terminals by providing parts corresponding to connection terminals with solder supply terminals and by making the soldering adhesiveness of this terminal lower than that of a connection terminal. CONSTITUTION:Solder 30 on a terminal 11 of a solder supply plate 10 is melted to move the solder 30 of this solder supply plate 10 to a connection terminal 21 of a board 20 or an electronic component 21, and the solder 30 is supplied to the connection terminal 21 by removal of the solder supply plate 10. At this time, making the soldering adhesiveness of this terminal 11 lower than that of the connection terminal 21 makes it easy to move and deposit the solder 30 which holds the terminal 11 to the connection terminal 21 of the electronic component 20. A method for making differences in the adhesiveness of the solder 30 between the terminals 11, 21 is to reduce the area of the terminal 11 of the solder supply plate 10: a possible method employed is a usage of a metal of an angle of contact with the molten solder 30 smaller than that of the metal used for the connection terminal 24 for the terminal 11 of the solder supply plate 10.

Title: Table moving device for sheet material working machine
Inventor: KOJIMA YASUHIRO
IPC: B21D43/00
Filed: 1989-04-24
Abstract: PURPOSE:To suppress the generation of hunting at the time of the stop of tables and to work sheet materials with high accuracy by detecting the weight of the sheet material placed on the tables, controlling the driving of the sheet material according to the detected weight and then moving the sheet material to a working section. CONSTITUTION:A servo motor 16 is driven by a control section 40 to move the moving tables 8, 9 imposed with the sheet material 11 in an Y-axis direction. A servo delay quantity is detected by a servo detecting circuit 35 and is inputted as the weight value of the sheet material 11 to the control section 40 which in turns stops the tables 8, 9. The control section 40 sets the time constants of the tables 8, 9 and work holders 13, 14 respectively according to the weight of the sheet material 11. The moving and stopping of the tables 8, 9 are then executed by using the set time constants to suppress the generation of the hunting at the time of the stop of the tables 8, 9. Further, a motor 20 is driven to move the work holders 13, 14 in the X-axis direction at the set time constants, by which the movement is rapidly and exactly controlled. The sheet material 11 is positioned between an upper turret 12 and a lower turret 22 in this way so that the sheet material can be worked with the high accuracy.

Title: Longitudinal cutter for flat slab
Inventor: HATSUTORI HIROSHI
IPC: B21B15/00
Filed: 1980-07-31
Abstract: PURPOSE: To cut a flat ingot hot longitudinally with high performance and form the same into optimum sectional shapes by forming both side parts of the flat ingot with edgers on the inlet side of cutting rolls and properly opening or closing appropriately a pair of guides for ingot on the inlet and outlet sides.  
     CONSTITUTION: A slab 8 is formed to the sectional shapes shown by the rolls 4a of edgers 4, and is shifted to the position of side guides 2. The guides 2 move forward and backward and backward each other (open and close) to firmly hold both side faces of the slab 8 thereby positioning the slab 8 in such a way that an intended cutting line passes the leading end position of the V-shaped cutting blades of cutting rolls 1. The slab 8 is screwed down by the rolls 1 and is shorn by the upper and lower cutting blades. Side guides 3 prevent the cut slab 8 from bending too much. The shapes of the cut parts of the cut slab are approximately the same as the shapes of both side parts of the slab 8 before cutting owing to the screwing down of the cutting blades, and this is advantageous for rolling in the next stage.

CONSTITUTION:When both photo diodes 3, 4 receive a reflected light from an object 24, the result is inputted to an inverting input of the differential amplifiers 9, 10 as pulse voltages V1, V2. Further, the voltage V1 is divided by voltage division resistors 11, 12 and the result is fed to a non-inverting input of the differential amplifier 10 as a reference voltage V3. The voltage V2 is divided by voltage division resistors 13, 14, and the result is fed to a non-inverting input of the differential amplifier 9 as the reference voltage V4. Then the differential amplifier 10 amplifies the difference between the reference voltage V3 and a pulse voltage v2 to generate a voltage V5 across a resistor 19. A comparator 20, when the voltage V5 exceeds a prescribed level, generates a photodetection output voltage V6. An integration circuit 22 integrates the photodetection output voltage V6, converts it into a DC output and eliminates noise, and conducts a transistor 23 to output the detection signal of the object 24.
