Abstract: An enclosure for data processing apparatus has a tambour door that slides in a track to partially open the front of the processor enclosure. The tambour door retracts completely into a canister that has a U shaped track that carries the tambour door. The canister is hinged along one edge of the processor frame so that the canister can be swung out to permit access completely along the front of the enclosure with a minimum of interference from the door and canister and with a minimum intrusion into an aisle alongside the processor.

Abstract: A matrix of small diameter holes are located in the module housing adjacent each of the integrated circuit chips to be cooled. A pin or rod is located in each of the holes and extends therefrom into contact with the exposed surface of the chip. A spring means is located between the housing and the pin to provide a predetermined spring loading of the pin-piston against the exposed surface of the chip. A header is located at the outer end of the pin-piston in contact with the exposed surface of the chip thereby, providing multiple pin-piston contact with the exposed surface of the chip regardless of the chip tilt which improves the heat transfer. The heat transfer can be controlled by including or removing pin-pistons in accordance with the heat transfer desired.

Abstract: An improved conduction cooled module of the type having at least one chip mounted on a substrate and having a housing surrounding the chips and sealed to the substrate. The housing having cylinders therein opposite the chips for containing pistons which are resiliently urged against the chip surface. Each piston has an opening extending from the top to the bottom surface and has at least one circumferential groove located in the outer wall of the piston. The opening and circumferential grooves are preloaded with a low melt point heat conductive material which is reflowed after assembly into the module to fill the interfaces formed between the piston and chip and the piston and cylinder. Grooves are located in the piston walls forming the interfaces which facilitate the flow of the molten material into the interfaces.

Abstract: Measurement of a time interval between a start and a stop event is made by activating a start oscillator in response to the start event and activating a stop oscillator in response to the stop event. The number of cycles of each respective oscillator signal which occur between the activation of each oscillator and the coincidence of the respective oscillator signal with that of an independent time base is determined. The number of cycles of the time base signal between the coincident points of it and the start and stop oscillator signal is also determined. These numbers, which are always integers, are used along with the values for the time base period and the difference in frequency between the time base oscillator and the start and stop oscillators to calculate the time interval. Resolution of the measurement is dependent on the frequency difference between the time base signal and the start and stop oscillator signals.
