Patent EP-0415544-A2 (EP)
Inventor: MATTA FARID
IPC: H01L21/60
Filed: 1990-07-20
Abstract: A Demountable Tape-Automated Bonding System for providing connections to a chip is disclosed. The chip is attached to or is held in place on a TAB frame that includes a generally flexible dielectric film which bears a pattern of conductive traces. A multitude of closely-spaced contacts which protrude downward from the chip contact the conductive traces on the TAB frame. The chip may be maintained in its proper location on the TAB frame by either a bonding agent or by compressive forces supplied by a cap which is fastened to the TAB frame and to a substrate, such as a printed circuit board, below the TAB frame. The substrate carries an array of conductive traces around the edges of the substrate. These traces match the traces on the TAB frame. The conductor traces on the TAB frame and on the substrate are held in contact with each other by compressive forces supplied by the cap which is fastened to the TAB frame and to the substrate. An optional bottom plate may be affixed beneath the substrate to provide additional strength and rigidity to the assembly. An optional heat sink may be attached above the cap to conduct away heat generated by the chip. An alternative embodiment of the invention includes an elastomer which is inserted between the cap and the substrate to cushion the compressive forces borne by the chip. The invention may also utilize a heat spreader placed directly above the chip. The Demountable Tape-Automated Bonding System constitutes a major improvement in the electronics industry which provides reliable, removable connections to delicate integrated circuit chips, eliminates the need for soldering, greatly diminishes alignment and bonding requirements, and offers a modular chip package that guards against mechanical, chemical, and electrical threats to its contents.

Abstract: An exhaustion fan device of a portable air conditioning apparatus (11), which includes an evaporation type condenser (13) cooled by water and air discharged to the outside of a defined space to be cooled, is stopped when the actual temperature Ta in the defined space reaches a prescribed value Ts to decrease an amount of water conveyed by air exhausted from the defined space to the outside of the defined space through the condenser (13). In addition, the stopping of the exhaustion fan device (35) prevents the actual temperature Ta in the defined space from fluctuating after the actual temperature Ta reaches the prescribed value Ts by decreasing the amount of air entering into the defined space from the outside of the defined space.

Abstract: Print heads 50, 60 are formed with spaced subheads 51, 52, 53, 61, 62, 63 having nozzles such that all of the lines or pixel rows on a print medium such as a sheet of paper are printed by scanning of the print head along the face of the sheet. The head structures include three subheads, each having nozzles for printing one or more adjacent lines with the subheads being spaced the same number of lines apart as the number of lines each prints; and three subheads spaced the equivalent of seven lines apart, each subhead having three nozzles spaced at the equivalent of alternate lines. The heads are advanced between scans by an equivalent number of lines generally equal to the number of nozzles in the head, whereby all print lines are addressed only once. Apparatus 70 for printing includes the use of pointers in registers 122, 124, 126, 128 to keep track of head structure and location on a print medium for calculating print addresses. A partial page memory 80 is used which wraps around to the beginning from the end. A positive printer carriage position encoder 180 uses an index marker 186 located in the middle of a strip 182 of incremental markers 184. Sensing of the index marker resets an up/down counter 198 with a value that gives a positive value for all count conditions.

Abstract: A tapped digital shift register suitable for use with a finite-impulse-response (FIR) filter in applications such as high-definition television is implemented using a random-access memory (RAM) 201. The RAM contains x words having yz bits each, where x represents the number of elements in each section of the shift register, y represents the number of taps and z represents the number of bits in each element. Words are continuously read from and written back into the RAM. Before being written back, each word is modified by removing a z-bit portion from one end (on 215) and appending a z-bit portion representing new information to the other end (from 217). The shift-register architecture disclosed is particularly suited for implementation on very-large-scale integrated circuits together with the FIR filter circuits.

Abstract: During the processing of a transaction or other distributed computation, a computation management system creates a number of agents to handle various aspects or portions of the computations to be performed. Each agent progresses through a predefined set of state transitions which define the status of the agent at any point in time. The computation management system defines for each agent a set of dependencies, each dependency corresponding to a state transition which will be blocked until a particular state transition occurs in another specified agent. By defining selected combinations of dependencies for each agent, a variety of different interdependencies and cooperating protocols can be implemented. The distributed processing management system can be used both for managing transaction processing and for synchronizing events in other types of distributed computations.
