Title: Method and device for automatic soldering
Inventor: YOKOTA SENICHI
IPC: B23K101/42
Filed: 1987-12-14
Abstract: PURPOSE:To prevent a bridge, icicle and drippings by projecting a molten solder from the plural small sized nozzles inclined at specified angle respectively for the transfer direction of a substrate and preventing the solder concentrating at the center part in the width direction of the substrate at soldering completion time. CONSTITUTION:A solder 4 is flowed in the direction of the arrow mark B by rotating an impeller 12 by starting a motor 18 after the solder of a secondary solder tank 8 becoming a molten solder 4 by being heated by a heater and is projected upward from each small sized nozzle 6. A primary soldering is executed by the nozzle 23 for primary soldering by transferring a substrate 1 in an arrow mark A direction by driving chain conveyors 26, 27 by a motor 28 to approach to the small sized nozzle 6 for secondary soldering. Due to the molten solder wave 4a having nine crests being inclined about 45 deg. for the progressing direction the solder flow in the orthogonal direction to the substrate direction is caused. The molten solder can be made not to be concentrated at the center part in the width direction of the substrate in case of its solder cut. As a result, the generation of various soldering defects can be prevented.

Title: Electronic circuit device
Inventor: TAWARA HIROKI
IPC: H05K3/32
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent breakage and degradation of the electrode of surface mounting type parts caused by a stress propagating in an adhesive material, by using, as a conductive bonding agent, a silicone group conductive bonding agent where a silicone group resin is mixed with a conductive filler. SOLUTION: An electrode 4 formed on both ends of a surface mounting type part 2 and a wiring film 3 of a printed board 1 are connected together with a silicone group conductive bonding agent 6. As for the silicone group conductive agent 6, a conductive filler, for example, a silver filler, is distributed in a silicone group resin to provide a conductivity, which is small in elastic modulus compared with a solder and an epoxy group conductive bonding agent. Thus, most of a force is absorbed by elasticity of the silicone group conductive bonding agent 6 itself, resulting in relaxed stress.

Abstract: PURPOSE:To enhance productivity and to prevent the damage to machinery by a method wherein one of a pair of rolls is formed into a truncated cone shape so that the outer diameter thereof expands in the axial direction of the roll and a safety apparatus contracting the gap between a bearing and a hydraulic cylinder against the elastic force of a spring is mounted. CONSTITUTION:A movable roll 4 has a columnar shape and a fixed roll 3 has a truncated cone shape and both rolls 3, 4 are adjusted by a hydraulic cylinder 5 so that the approach peripheral surfaces of the rolls 3, 4 become parallel to generate a predetermined roll gap delta. The number of rotations of the roll 3 and that of the roll 4 are constant but the speeds thereof become same only at an intersecting point E but become different at the other part and a raw material to be ground receives shearing force along with compression force to pass through the gap between both rolls 3, 4. When abnormally large force acts on the rolls 3, 4 by the foreign matter bitten between both rolls 3, 4, the disc 4e of the safety device 20 interposed between the bearing 4a of the roll 4 and the hydraulic cylinder 5 is suddenly moved leftwardly to expand the gap between both rolls 3, 4 to exclude the foreign matter. After the foreign matter is excluded, a steel ball 27 is moved rightwardly by the energizing force of a compression coil spring 28 and received in a notch 21a to stop.

Title: Automatic focusing device
Inventor: MAKIHIRA HIROSHI
IPC: G02B7/28
Filed: 1987-12-16
Abstract: PURPOSE:To simplify an optical system structure and adjustment by determining bright and dark sample positions by means of using a strip pattern detecting signal outputted from an image sensor as reference and storing the positions in a memory. CONSTITUTION:According to the strip pattern detecting signal from the image sensor 1, the bright and dark positions of a pattern are detected, and their sample images are automatically determined and stored in the memory 7. Therefore the stored position information always coincides with the bright and dark positions indicated by the strip pattern detecting signal, whereby conventionally required adjustments, that is, adjustment for positioning an image sensor to match the bright and dark positions of a strip pattern to preset sample positions in image elements composing an image sensor, and magnification adjustment, are not needed. Thus an adjusting mechanism and adjusting work can be simplified.

Abstract: PROBLEM TO BE SOLVED: To provide an assembling method by which gold wires can be bonded to copper pads on a substrate in excellent states and, at the same time, solder bumps can be formed on the copper pads in excellent forms. SOLUTION: The first and second pads 14 and 16 of a substrate 11 are formed by respectively forming thin gold films 22 and 24 on copper pads 21 and 23. In this case, an oxide film 25 which is formed on the surface of the film 22 owing to the diffusion of the copper contained in the pad 21 in the film 22 is removed by plasma etching. Electronic parts are assembled by bonding gold wires to the gold film 22 on the first pad 14 and forming a solder bump on the gold film 24 on the second pad 16. Therefore, the cost of the electronic parts can be reduced by eliminating the need of any nickel film and reducing the thicknesses of the gold films 22 and 24. In addition, the gold wires can be bonded firmly to the solder bump.
