Patent JP-H09186285-A (JP)
Title: Double layer lead frame
Inventor: SEGAWA TAKAO
IPC: H01L23/50
Filed: 1996-01-04
Abstract: PROBLEM TO BE SOLVED: To easily engage a heat radiating plate and a suspending lead at a lower manufacturing cost by inserting a projection for engagement into an engaging hole formed at the engaging part of the suspending lead and providing thereby the engaging condition by deforming the head of the projection for engagement with the deforming process. SOLUTION: Before engagement with a lead frame, a heat radiating plate 4 allows the projection 5 for engagement to be formed with the press machining at the area to be engaged with a suspending lead 2. Next, the projection 5 for engagement formed on the heat radiating plate 4 is inserted to a hole 6 for engagement provided at the suspending lead 2 in order to obtain a double- lead frame. Next, the head of projection is deformed by pressing the head of the projection 5 for engagement projected from the surface of the suspending lead 2 and thereby the heat radiating plate 4 and suspending lead 2 can be caulked. Thereby, the double-surface adhesive tape or laser welder which has been required for the double-layer lead frame of the related art is now unnecessary and manufacturing cost of the double-layer lead frame can be lowered.

Abstract: 1409971 Melting mineral ROCKWOOL AB 2 Jan 1973 [11 Jan 1972] 193/73 Heading C5G In a method of melting mineral in a cokefired shaft furnace, batch coke lumps, fed into the furnace and passed vertically down through the furnace in countercurrent to hot stack gases, are coated with a solid surface layer of melting point sufficiently high to prevent reduction of the CO 2  in the stack gases by the coke up to the edge of the combustion zone. The surface layer may be applied by spraying a slurry on to the lumps or dipping them in a slurry or paste. The slurry may be of lime in water. Binding agents such as glue or plaster, or soluble or hydraulic binding agents may be present. The surface layer may also contain material soluble in the bloom of the mineral, e.g. metal oxide.

Abstract: 1522901 Securing loads to pallets FMC CORP 6 Jan 1976 [29 April 1975] 00277/76 Heading B8C  Apparatus for strapping an article K to the deck of a pallet P comprises means for passing a strap over the article on the pallet, said means being operated by a pneumatic or hydraulic motor; and a strap guiding lance L which is advancable under the deck of the pallet to guide the strap under the pallet, the lance being advanced and retracted by an electric motor 21, the electric control being dependent on the fluid-pressure circuit. Into a strap guide frame F is placed a pallet P carrying a load K which is to be strapped to the pallet. A carriage 88 is moved along a guide bar 86 by an electric motor 21 to advance the lance L under the deck of the pallet until the free end engages a projection 79a at the foot of the far side of the strap guide frame, thereby providing strap guiding means which fully encircles the pallet P and load K. A reel 16 dispenses continuous heatsealable strap material S. A pneumatically operated strap feeding mechanism M feeds strap material up the near side of the strap guide frame F, over the top, down the far side, back along the lance, and up the near side of the frame F to a sealing and gripping mechanism g Corner guides 76, 76a, 76b and 76c (this latter being suitably positioned in the fully extended position of the lance) guide the leading edge of the strap material round the comers. The sealing and gripping mechanism g grips the free end of the strap whilst the pneumatic motor supplying the strap material is reversed to pull the strap tight about pallet and load, and includes means for heat-sealing together the ends of the strap material encircling the pallet and load, and for severing said encircling strap material from the continuous supply. In operation, the electric motor 21 is then reversed to withdraw the lance L from beneath the deck of the pallet.

Abstract: 309,422. Aldinger, OÀ Jan. 7 1928. Heating by electricity.-In apparatus for drying the hands, an electric motor 3 coupled to a fan 5 for driving air over electric heating elements 7 is controlled by a switch 12 which automatically stops the motor after it has run for a predetermined time. The arm 13 of the time switch closes the circuit of the heating elements on reaching the contact 14 and after a predetermined time reaches the contact 15 and closes' the motor circuit. Figs. 2 and 3 show a particular construction of time switch. The clockwork is wound up by turning the nut 27 with consequent release of the arm 25 and closure of contacts 19, 21 to close the heater circuit. The arm 29 rotates and on reaching the strip 31 closes the motor circuit. On leaving the strip at the other end the motor circuit is broken, the arm 25 is retracted to open the heater circuit, and a clutch is released to enable the arm 29 to be returned by a spring.

Apparatus for feeding lasts into fibre-soled shoes to facilitate sewing, comprises a pair of inclined rails located above a train of moving shoes, lasts having projections for engaging the Tails, means at the lower end of the rails to introduce the lasts into the shoes, and means for removing the lasts from the shoes and carrying the lasts to the upper part of the rails. The lasts 5 are removed from the shoes by rotating arms 21 which engage the projections 6 to carry the lasts to the upper end of the rails 1. Lasts sliding from the upper part of the rails are checked by a stop 10 on a lever 7. The lever is connected by a rod 18 to a cranked lever 16a, 16 in turn connected by a rod 15 to a cranked lever 13, 14. The lever 16, 16a is fixed to a member 9 pivoted at 24 and having release members 19. A last carried by a shoe in the train 2 engages the arm 13 to release the last checked by the stop, and to lower the end of the member 9 placing an intermediate last in the path of the next shoe. Movement of the shoe releases the intermediate last from the member 9, and springs urge the members 7, 9, 19, 13 back to the position shown in the figure so that a last is checked by the stop, an intermediate last is held in the member 9 by the release members, and the last just released is underneath the arm 13. The lasts are pressed whilst the shoes are sewn at a position under the middle of the rails.

The delivery end of a jigging conveyer 2 is straddled by a two-part frame 1, Figs. 1 and 1A, each part of which comprises pairs of skids 4, leg members 3 and side members 5. The members 5 of the two parts.are jointed at 6, the relative inclination of the parts being determined by the angle of the wedge 7 inserted between' them. A jigging elevator 8 is supported by horizontal rollers 9 and guided by vertical rollers 11 mounted on the members 5. This elevator is pivotally connected to a feeding trough 18 and a delivery trough 19, the latter of which is supported by a vertically adjustable rocker frame 21. The elevator .8 is connected by a rod 13 to a T-sectionbar 14 which lies in a trough 15 of the conveyer and can be secured thereto by a clamp 16 mounted thereon. The jaws 47, Fig. 5, of the clamp are mounted on pivot pins 45, 46 in a member 41, Fig. 4, which is pivoted at one end 42 to a spring- controlled push rod 43 and at the other end 40 to a link 38. This link is mounted on the eccentric part of aspindle 36 which can be turned through 180 degrees by a handle 37 and locked in either extreme position by a spring-loaded plunger 54. The pin 46 is mounted in a slot and is adjusted to vary the distance between the jaws by a bolt 48. The frame. and elevator are moved backwards as filling proceeds by releasing the clamp at the end of a return stroke of the conveyer and re-engaging it with the bar 14 at the end of a subsequent forward stroke. The bar then moves backwards and draws the elevator with it, so bringing a spring 24 into contact with a stop 25 on the frame to move the frame backwards.
