Patent IT-1020252-B (IT)
IPC: B23K1/20
Filed: 1974-08-28
Granted: 1977-12-20
Abstract: A flat surface of a semiconductor chip is soldered to a relatively larger flat surface of a heat sink by forming a plurality of closely spaced grooves in the flat surface of the heat sink, coating the flat surfaces of the chip and the heat sink with nickel, disposing solder between the coated surfaces of the chip and the heat sink, and heating the surfaces until the solder melts. The grooves in the heat sink prevent the entrapment of gas bubbles between the chip and the heat sink, thereby providing good thermal conductivity and a relatively low electrical resistance between the chip and the heat sink.

Patent PT-82331-B (PT)
IPC: H01H71/50
Filed: 1986-04-02
Abstract: In the switching mechanism, a rigid contact lever (4), provided with a latching point (4a) can be latched via a spring-loaded manual operating toggle (2) and a pawl bracket (3). The contact lever (4), preferably designed as a flat stamped part, can in this case swivel freely with a longitudinal cut-out (4b) about a shaft (5) fixed to the housing. In this way, the contact lever (4) is supported in the braced state merely on the latching point (4a) and with its contact point (4c) on a fixed contact piece (6). The contact force is applied by a tension spring (10) which also causes the contacts to open on the basis of its point of application on the contact lever (4). Significant to the invention in this case is the point of application of the tension spring (10) in an eye (4e) which is located in the direction of tension in front of the two supporting points (latching point 4a, contact point 4c) and between the latching point (4a) and the longitudinal cut-out (4b). In addition, the tension spring (10) is suspended on the housing point (1d) at the same height as the contact lever (4), so that the direction of its effect coincides with the functional plane or plane of swivelling of the contact lever (4). In this way, the tension spring (10) has a stabilising effect on the flat contact lever (4) and tipping or slanting is prevented.

Abstract: A video signal generator employs a host subsystem (11), display controller system (18), display generator subsystem (20), refresh memory subsystem (24), and video data system (28) to process pixel data in parallel to achieve high pixel frequency rates permitting large flicker-free images. To achieve high pixel frequencies, parallel processing is maintained from the bit map memory (36) until the data is processed by the digital-to-analog converter (DAC) (54). The display generator subsytem (20) outputs a multi-bit digital data address signal (35) which is used to address a plurality of bit map memory (BMM) arrays (36). The BMM arrays (36) operate in parallel, and the data (35) is read into a portion of each BMM array (37, 39) until the array (37, 39) is filled. The data is read out of the arrays (37, 39) in parallel (32) and into a plurality of BMM output multiplexers (MOM) (38), new data continuously being read into each BMM array (37, 39). The MOM (38) time division multiplexes the data signal (32) into data nibbles (26), of fewer bits, representing the color intensity of the data signals (32). The data nibbles (26) are multiplexed by a plurality of video multiplexers (40) to produce a multi-bit color intensity code )44) which is used to address a plurality of color look-up tables (CLUTs) (40). The CLUTs (40) select the array data for display, and generate color codes (48). The color codes (48) are multiplexed to the desired pixel frequency rate and are input into DACs (54) to drive a monitor (58).
