Abstract: A powder dispensing assembly (10) including an elongated chute (34) having opposite ends (40) pivotally supported for rotation about a pivot axis (38) within an elongated housing (20) and having a funnel-shaped cross-section with a wide upper portion (42) and a narrow lower portion. A dispensing platform (26) is integral with the rear wall (46) of the chute (34) and extends forwardly beneath the front wall (44) and slopes upwardly to a lip (28) over which particles of powder move to define a falling curtain of powder particles. A supply platform (30) is supported just above the pivot axis (38) and receives powder from an elongated slot (32) and supplies powder to the dispensing platform (26) as the powder falls downwardly through the chute (34). The supply platform (30) is wider than the angle of repose of the powder supplied thereto so that when the supply platform is not moving powder is not being supplied to the lower dispensing platform (26). An electromagnet (80) co-operates with a spring plate (66) which is, in turn, connected by a rod (58) through the housing to the rear wall (46) of the chute (34). The electromagnet (80) operates on 60 cycle AC and, when energised, sets up a magnetic field to bend the spring plate (66) to rotate the chute (34) in a counter-clockwise direction about its pivot axis (38) and between cycles the spring plate (66) springs back and returns the chute (34) by rotating it in the clockwise direction. The upper supply platform (30), therefore, rocks about the pivot axis (38) to supply powder to the lower dispensing platform (26), the supply of powder from the supply platform (30) being less than the capacity of the dispensing platform (26).

Abstract: The invention concerns a plane die-cutting machine for die-cutting laminar material, of the type comprising a plane punch and an arc-shaped counter punch, which is controlled by moving means pressing the same against a work material inserted between it and the punch, said counter punch being simultaneously rotated around a line of instant-contact which runs along the punch. To avoid impacts between the reciprocally moving parts, the invention provides extensions integral to the punch and to the counter-punch, which maintain the contact between these latter for a portion of the reciprocal oscillatory movement outside the die-cutting area, so that said reciprocal oscillatory movement takes place with constantly contacting zones, like a blotter of blotting-paper.The die-cutting area is defined in such a way that, when the reciprocally moving parts contact themselves at the ends of said extensions, between the die-cutting parts a hollow space is left, which is sufficient for the passage of the laminar material under work.

Abstract: Asynchronous bus multiprocessor system where a plurality of microprogrammed processors communicate with a working memory through a common bus (DAC BUS). 
<??>Microinstructions can be read out from working memory. 
<??>At least one of the processors, in addition to conventional bus interface registers for latching of data, address, commands to be forwarded to the working memory through the bus, is provided with an additional interface register (39), devoted to the latching of a microinstruction address for a microinstruction to be read out from the working memory. It is further provided with a multiplexer (17) for selectively loading a microinstruction register either from a microprogram control memory or from the system common bus. 
<??>A direct path (25) is established between the system common bus and an input set of the multiplexer. 
<??>The microinstruction transfer speed from working memory to the processor is enhanced by means of different timing for the data transfer through the bus and the microinstruction transfer through the bus. Whilst in case of data transfer a bus access cycle is started at the end of the processor cycle during which the relevant bus interface register are loaded, in the case of microinstruction read out from working memory, the additional interface register is loaded at the beginning of a processor cycle concurrently with the request of bus access cycle, so that the two may overlap.

Abstract: A method of attaching semiconductor die to a package substrate and a composition for such die attach is disclosed, which method and composition comprise the combination of a low and a high-melting powder with a vehicle consisting of a solvent and a binder so as to form a thick-film ink. The ink is deposited onto the package substrate and the semiconductor die with a metallized back surface is located in contact with the deposited ink. The package containing the ink and the die is heated to a temperature of approximately 160 °C so as to remove the solvent from the powders and the residual binder. Next, the package is fired at a temperature within the range of approximately 200 °C to 430 °C so as to melt the low-melting powder which bonds the chip to the package substrate. Then, a lid is sealed over the die-receiving cavity of the package by heating the package and the bonded die to a temperature within a range of approximately 400°C to 450°C wherein the low-melting powder remelts and the high-melting powder partially dissolves into the liquid of the remelted low-melting powder.
