摘要:
A heating device for heating a recording sheet. The heating device has a first heater located within a heating roller. The first heater has a heat distribution effective to form a low temperature region in an axially central portion of the heating roller and a high temperature region in each of axially opposite end portions of the heating roller. There is a second heater located within the heating roller that has a heat distribution effective to form a high temperature region in the axially central portion of the heating roller, a low temperature region in each of the opposite end portions of the heating roller, and a second-level high temperature region in each of axially opposite end portions of the high temperature region, the second-level high temperature region being lower in temperature than the high temperature region.
摘要:
A selective sputtering method and resulting substrate are provided. This may involve obtaining a substrate and identifying a die placement area and a keep out area of the substrate. A protective area may be formed over the substrate between the die placement area and the keep out area. This may be done using a selective sputtering process. Underfill material may be provided over at least the die placement area of the substrate without the underfill material flowing to the keep out area based on the surface roughness of the keep out area.

摘要:
A device for automatically fixing bus bars and after-fixing bus bars on an insulating board includes a workpiece setting table, on which a bus bar plate and an insulating board are set, is moved towards an upper die and a lower die, which are provided with an insulating board holding section and a bridge cutting and bus bar fixing section. The upper die is moved downwardly and upwardly, so that the bridges are removed from the bus bar plate, and the insulating board is picked up. Thereafter, an insulating board holding board holding the insulating board is moved to the bridge cutting and bus bar fixing section. The upper die is moved downwardly and upwardly again, so that bus bars are fixed onto the insulating board. As the upper die moves downwardly and then upwardly, the bridges are removed from the bus bar plate, and the insulating board and the intermediate product are lifted. Under this condition, the holding board is moved toward the cut punch plate, and the upper die is moved again downwardly and then upwardly, so that the first-fixing group of bus bars are fixed onto the insulating board while the after-fixing group of bus bars are fixed onto the intermediate product, whereby an intermediate product and a complete product are newly formed.
摘要:
A mounting board having a plurality of terminals. The ends of each of the plurality of terminals are inserted into and soldered to through-holes positioned in a printed board, and the terminals are mounted on the printed board. A plurality of pedestals are disposed on one side of the printed board. The pedestals support the terminals. The pedestals are integrally coupled to one another through deformable coupling portions. Mutual displacements among the pedestals are allowed by the coupling portions.
