Title: Interface for disk drives
Inventor: BIZJAK JOHN F
IPC: G11B19/02
Filed: 1991-11-06
Abstract: A disk drive that can read from and write to both standard floppy disks and high capacity floppy disks. The present invention provides a single slot disk drive that can accept both standard floppy disks and high capacity floppy disks. After a floppy disk is inserted, physical cues on the floppy disk are used to inform the disk drive as to the nature (standard or high capacity) of the inserted disk. The disk drive incorporates two interfaces, a standard floppy disk controller (39, 22) and an IDE interface (38, 21) for high capacity disks. The disk drive is configured so that both interfaces can communicate with a host computer at all times, regardless of what type of disk is inserted in the disk drive. This allows the host computer to operate as if it had two separate disk drives available.

Abstract: The invention relates to a power source, especially a welding power source, and a method for controlling it. In order to be able to control the magnitude of the output current more easily and precisely, it is proposed to frequency-modulate the input voltage on the primary side of the transformer. To this end, a controllable invertor (7) is arranged in the power source (1) on the primary side of the transformer (8) and is acted on by a controller (6). The controller (6) may also carry out network compensation (15). It is equipped with a dedicated microprocessor (12) or may be connected to a central process controller (14). <IMAGE>

Abstract: In a preferred embodiment of the invention, an evaporator core (10) for an automotive air-conditioning system or the like comprises a brazed plate-and-fin heat exchanger (12) formed of aluminium alloy and having air passages (20) opening at an upstream face (21). The evaporator core (10) further comprises a biocidal fixture (14) attached to the upstream face (21) of the heat exchanger. The fixture (14) comprises a carrier (26) formed of an electrically non-conductive polymer and a metallic copper plating (40) deposited on the surface of the carrier (26) spaced apart from the heat exchanger (12). During air-conditioning operations, condensate collecting on the copper surfaces reacts with the copper to generate cupric ions that disperse in the condensate to inhibit biological growth within the heat exchanger passages (20). Moreover, the carrier (26) electrically, as well as physically, isolates the copper from the aluminium to prevent galvanic coupling that would otherwise produce accelerated corrosion of the heat exchanger (12).

Abstract: A mechanism for handling processing errors in a computer system. The mechanism includes a first means for processing a stream of instructions, second means for detecting an error caused by a timing dependant defect and occurring during processing of the instruction by the first means and third means for varying the instruction processing cycle time of the first means in response to the detection of the error by the second means, and for causing the second means to retry at least a portion of the instruction subsequent to the varying. In a preferred embodiment, the mechanism uses the variable frequency oscillator, controlled by recovery code, to increase the system clock cycle time by a specified time (Textend) following what has been determined to be a critical fail and after normal retry has been unsuccessful. The increased cycle time extends the net slack and, thereby, provides tolerance to certain AC (path delay) defects which have developed in any cycle time dependant latch to latch segment. The time (T) is chosen based on maximum cycle time restrictions resulting, for example, from the pipelining of data in system cables.

Abstract: Process for treating room air for the human domain, in particular for living rooms and work rooms, in which the room air to be treated has or can have physically and/or chemically separable pollutants. The room air is treated climatically in a climate-control apparatus and transported by a blower in the region of the climate control apparatus. In at least one oxidiser, the room air is treated with ozone generated in an ozoniser, for the oxidation of oxidizable pollutants. The room air coming from the oxidiser is treated in at least one filter device having a conversion filter for converting ozone into stable molecular oxygen and the room air coming from the filter device is analysed for ozone by at least one ozone sensor. The ozone generated in the ozoniser is controlled and/or regulated in terms of volume depending on electrical signals from the ozone sensor. The treated room air is vented through at least one outlet channel having an air outlet into the assigned room to be climatised. Before the treatment in the oxidiser, the room air is analysed quantitatively for oxidisable pollutants by at least one pollutant sensor and the ozone generated in the ozoniser is additionally controlled and/or regulated in terms of volume depending on electrical signals from the pollutant sensor. The room air coming from the filter device, before the analysis with the ozone sensor, is impinged with ozone concentration pulses by a self-test ozoniser. In the absence of electrical self-test signals from the ozone sensor, the ozoniser is controlled into a stand-by state. An air-conditioning unit for carrying out the process is also specified. <IMAGE>
