Patent EP-0393915-A2 (EP)
Inventor: BROOKS PETER EVERETT
IPC: G11B23/50
Filed: 1990-04-10
Abstract: A disk drive includes a cast base 5 which supports the spindle assembly and the actuator assembly, and a cover 11 that is loosely received by the cast base to form the head-disk enclosure. The cover is secured and sealed to the cast base by a malleable metal foil tape 30 that surrounds the enclosure and continuously overlies the interface between cover and base. The tape complies with the surface irregularities and does not creep, to provide permanent shielding and sealing between base and cover. Cable exiting the enclosure is sealed using a piece of double sided adhesive between the cable and the casting, with the malleable foil tape thereover. Thus no significant thickness is added to the enclosure by the tape, which also provides noise and EMC shielding in addition to securing and sealing the cover.

Abstract: A roll-up door for enclosing a doorway in a building. The door comprises a horizontal rotatable drum mounted above the doorway and a flexible door panel (8) is wound on the drum. A pair of first pulleys (17) are secured to opposite ends of the drum and one end of a flat belt (18) is secured to each first pulley, while the opposite end of each belt is dead-ended on a fixed object. A counterbalancing weight (23) is attached to the belt intermediate its ends and exerts a counterbalanc­ing force to wind the door panel (8) on the drum. A pair of second pulleys (27) are secured to opposite ends of the drum and located adjacent the first pulleys. One end of a second flat belt (28) is secured to each second pulley (27), while the opposite end of each second belt is connected to the lower end of the door panel (8). A drive member, such as a hydraulic motor (9), is operably connected to the drum and operation of the motor in one direction will unwind the door panel from the drum and move the door to a closed position, while operation of the motor in the opposite direction will wind the door panel on the drum to move the door panel to an open position. A resilient member or spring (37) is connected to the second belt (28) intermediate its ends and exerts a biasing force to stretch the door panel.

Abstract: The invention relates to a method of forming a crystalline metal oxide body from sinterable material. During conventional manufacture of such bodies, they are subject to much handling as they are shaped and ground prior to the final sintering. With this handling, there is a risk that invisible cracks will be produced on the edges and propagate on sintering. 
     The invention provides a method of manufacture wherein a presintered body (12) is produced and a partial cut (16b) made preventing any cracks produced at the edges of the presintered body from propagating through the body during sintering. The sintered body can then be broken at the cut-region to remove the cracked, and possibly chipped, edges and produce a body of the required shape.

Abstract: For the production of nitrogen by means of membrane separation, the feed gas used is the waste gas forming in the combustion of hydrocarbons with air. As a result of the combustion, the oxygen from the air is bound, so that the purity of the nitrogen produced from the waste gas increases. If an internal combustion engine is used for producing the waste gas, the feed gas obtained is already under pressure and heated, so that a lower compressor power suffices for the compression of the feed gas before the membrane separation and gas preheater stations can be omitted. Moreover, the internal combustion engine can serve as drive for the feed gas compressor.

Abstract: In a communication system (100) that performs radio channel management, there is a method and and apparatus for reducing contention and superfluous channel allocation between a plurality of mobile units (101,102 and 103), making multiple requests. In this effort, upon receipt of an access request (at 210 or 510) and after a determination that communication resources are available (at 530-570), the system determines an access request count (at 310) for each received access request. Thereafter, the system is responsible for altering system resources (at 360 or 370) as a function of the access request count in order to reduce the likelihood of contention. In addition, the system (100) is designed to determine a system processing delay (at 610) for each received access request and thereafter adjust a range of mobile unit retry intervals ((at 645 or 655) as a function of the processing delay, whereby the likelihood of more than one channel being assigned to a unit making multiple requests is reduced.

Abstract: A stopwatch stores a lap time, measured by the operation of a lap switch (3), in a RAM (2). When the lap switch is operated, a minute hand (12) is immediately moved to a 0 o'clock position, and is started its rotation. The hand is rotated at such speed that the hand arrives at a 10 o'clock position after the preceding lap time stored in the RAM is elapsed. For the rotation of the hand at that speed a microprocessor unit (1) calculates the time interval to supply pulse signal to a step motor (10). Since the hand is moved to the 10 o'clock position at that speed, percentage of the lap time being measured at present to the preceding lap time can be immediately known.

Abstract: This protocol data generator-analyzer encodes and decodes protocol data units, which are transfer syntaxes used in data communications, for setting of or reference to the values as components of the protocol data units. First, table generation means (12) generates, from an abstract syntax (11) described according to an international standard specification as input data, a machine-processible table showing the data structure of the abstract syntax. For encoding of a protocol data unit, component data input means (14) inputs the values of protocol data unit components. List generation/reference means (15) generates a list having values corresponding to the data structure of the abstract syntax based on the values input by the component data input means (14) during encoding, and converts the values to those referable using the list during decoding. Protocol data unit encoding/decoding means (17) encodes sending protocol data units (18) by inputting the table and list or decodes received protocol data units (19) based on the table for list generation. Component data reference means (20) refers to the values converted by the list generation/reference means (15) based on the list generated by decoding of received protocol data units.

Abstract: A regulated power supply provides a regulated supply voltage at a preselected level under normal operating conditions. When power demands of the circuitry driven by the supply requires a higher voltage, the supply adapts to supply such a higher voltage. Such a supply can be used with automotive electronic circuitry, and can supply voltages up to approximately the voltage available on an automobile battery when such higher power demands occur. The higher supply voltages remain regulated, and return to normal levels when the extra power requirement is removed.
