Title: Lead frame
Inventor: TSUMORI MASAHIKO
IPC: H01L23/495
Filed: 1984-10-29
Abstract: PURPOSE:To inhibit warp, curing, and undulation after resin molding so that transfer and positioning can be accurately carried out, by a method wherein a pair of slits are formed alternately from inner and outer rims at a suitable point of a band plate section in the oblique direction to its longitudinal direction. CONSTITUTION:At the middle point between resin-molded parts 3, 3 disposed in an array at fixed pitches, slits 6, 6 are cut alternately from the inner and outer rims of the band plate section 1 in an oblique manner to the longitudinal direction. The place and number of slits 6 are suitably selected according to the degree or distribution of the thermal shrinkage of the part 3. The band plate section 1 receives compression stress in the longitudinal direction with the thermal shrinkage accompanying the cooling after resin molding; however, this stress is absorbed by the deformation of the slits 6, and so deformation, warp, curving, and undulation do not generate. Although the band plate section 1 receives tensile force in the longitudinal direction during the transfer of lead frames having element main bodies, the lead frames do not elongate unexpectedly because the tensile force branches into the component in the depth direction of the slit 6 and the component in the width direction.

Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To lessen the soaring up of iron oxide and to rapidly improve bulk density by charging iron oxide powder having a specific apparent bulk density within the hermetic vessel of a roller type compacting machine and reducing the inside of this hermetic vessel to a specific vacuum degree and actuating a revolving roller and revolving plough to revolve. SOLUTION: The roller type compacting machine constituted by revolvably disposing a revolving roller which is perpendicularly revolvable on the bottom plate of the hermetic vessel and disposing the revolving plough for guiding the powder on the revolving orbit of the revolving roller is used. The iron oxide having the apparent bulk density of 0.4 to 0.6 is charged into the hermetic vessel and the inside of the hermetic vessel is decompressed to the vacuum degree of 200 to 100Torr. The revolving roller and revolving plough described above are actuated to revolve at a revolving speed of 1 to 2m/second, by which the iron oxide powder having the high bulk density is obtd. The bulk density increases rapidly from the atm. pressure (760Torr) and the high bulk density is obtd. in the final as the vacuum degree is lower (160Torr).  The probable reason thereof lies in that the soaring up of the iron oxide is substantially eliminated by the reduced pressure and that the iron oxide is effectively meshed into the lower part of the revolving roller.

Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a handle bar vibration control device which can change a resonance point easily without changing the weight of a dead weight largely, and whose fitting work is easy. SOLUTION: At the opening end part of a handle bar 1, a vibration absorbing rod 12 extending in the axial direction of a handle bar 1 is fixed so as to be overhung, a resonance point is changed easily so as to reduce amplitude by changing the length and the diameter of the vibration absorbing rod 12, and the need for changing largely the weight of a dead weight 10, which was required for a conventional type, is eliminated. A resonance point can be also changed without changing the length of the vibration absorbing rod 12 largely by forming a swelling part 21 at the front end of the vibration absorbing rod 12 and changing its shape and size.  It is thus possible to facilitate fitting work by forming such a structure as a nut 11 is pushed into an expandable cylindrical part 16 uncluding a slit 17 by a bolt 13 which is inserted from the outside of the dead weight 10 to bring the cylindrical part 16 into pressure contact with the inner periphery surface of the handle bar.
