Title: Improved position sensor
Inventor: MORELLI DONALD THOMAS
IPC: H01L43/08
Filed: 1989-07-13
Abstract: For increased sensitivity an improved position sensor includes a magnetic circuit in which a stationary portion (20) includes a permanent magnet (22) whose width (W) is optimally 1.5 times the tooth pitch of an exciter portion (12) of the sensor and the magnet face proximate the exciter portion (12) includes a thin layer (24) of ferromagnetic material over which is centred a narrow magnetic sensing element (16), such as a magnetoresistor. The sensing element (16) has a width typically less than the tooth width. The sensing element includes a thin film of a monocrystalline semi-conductive material, preferably having only a moderate bulk mobility and a larger band gap, such as indium arsenide. Current carriers flow along the length of the thin film in a surface accumulation layer, effective to provide a significant apparent increase in mobility and conductivity of said semi-conductive material, and an actual increase in magnetic sensitivity and temperature insensitivity. The flux density is typically applied by appropriate magnet thickness or choice of magnet material without the need of a flux guide.

Abstract: A dyesheet for thermal transfer printing comprises a substrate supporting a transfer coat comprising a plurality of uniform panels containing different coloured thermally transferable dyes, and a further panel in which instead of a coloured dye there is a thermally transferable colourless absorber of ultraviolet radiation. Using such a dyesheet, a layer of UV absorber can be applied very simply as an extension of the printing process, by causing the receiver to pass through the printer once more, in contact with the further panel, essentially as though the UV absorber were merely a further colour to be added to the print.

Abstract: The invention relates to a device for the aspiration and addition of additives in a fluid flow by means of a T-shaped connection piece having a through-channel for the fluid and a connecting channel, opening perpendicularly thereto, for the additive. To generate a sufficiently high vacuum, a stopper projects transversely into the fluid flow, so that the fluid flow is largely blocked and only narrow flow gaps to the side of the stopper remain free. As a result, such a high vacuum is generated on the side of the stopper remote from the flow that even gel-like substances such as bath additives and the like can be sucked off there. <IMAGE>

Abstract: A mechanical ultrasonic scanner includes a trans­ducer element (11) which is swingably supported in a housing, and a sensor (15) for detecting a swinging angle of the transducer element (11). The sensor (15) includes a permanent magnet (13) swung together with the transducer element (11), and a magnetoresistive element (14-1, 14-2) fixed to the housing (4) to be opposite to a swinging locus of the permanent magnet (13). The per­manent magnet (13) generates a magnetic field between the permanent magnet (13) and the magnetoresistive element (14-1, 14-2). The magnetoresistive element (14-1, 14-2) detects a strength of the magnetic field which changes in correspondence with a swinging angle of the magnet (13), so that the swinging angle of the tra­nsducer element (11) is detected on the basis of the change in the strength of the magnetic field. Even if the housing (4) contains a sound transmitting medium, the magnetic field generated by the sensor (15) is not adversely affected by the sound transmitting medium. Therefore, the swinging angle of the transducer element (11) can be accurately detected to accurately obtain a radiating/returning direction of an ultrasonic beam, thus accurately reconstructing an image. In addition, the position of the transducer element (11) can be con­trolled with high precision.

Abstract: A dual port, random access, read/write memory (14) is provided such that each microprocessor (10,11) can access shared memory locations without regard to the state of the other microprocessor. Previously known dual port systems use delays, called wait states, or handshaking techniques to control memory access and to resolve overlapping memory access requests. This invention avoids the need for special timing controls by improving memory response time. Once a valid address is placed on the address bus (22,25) by the microprocessor (10,11), which is recognised by the memory (33) as being within its range of assigned address values, the memory prefetches the data at that address on the chance that a read request for that address may soon follow. If it does, then the data is placed on the data bus. If it does not, then the prefetched data is ignored and a write operation takes place for the particular address.

Abstract: Disclosed is an optical disk handling system (24), called an autochanger, having two control systems (1504, 1502) to provide the six motions necessary to move optical disk cartridges (43) from storage holding cells (40) to an optical drive (26). Whenever the mechanisms are being moved, the control systems monitor the progress of the movement, and should the control systems detect an error condition, a state update flag is changed to prevent further updates of the state of the system (176). With state updates disabled, the control systems (1504, 1502) will stop all mechanisms and prevent further movement of the mechanisms. The software that calls the control systems (404, 406, 408, 410), however, is unaware of this change in the state update flag, and continues to process until the operation appears complete. When the operation appears complete, an error recovery software function (412) is called. When the error recovery software (412) detects that the state update flag is in an error condition, error recovery is initiated. The type of error recovery performed is based on the state of the machine (176) at the time the error condition was first detected, since this state has been saved by changing the state update flag. The first part of error recovery (422) attempts to put the mechanisms into a known state, based on the mechanisms positions at the time of the error. After the mechanism's state has been established, error recovery movement is started, based on the operation that was being performed at the time of the error, and the state of the machine (176) at the time of the error. The type  operation being performed is saved in non-volatile memory, so that the type of operation will be saved should electrical power fail during the operation. Therefore, after power is restored, power fail error recovery can perform error recovery based on the type of operation being attempted at the time power was lost.

Abstract: Frequency variation in a resonant zero voltage switching (ZVS) power converter is combined with supplemental duty cycle modulation to obtain voltage regulation and to narrow the required frequency band needed for regulation of a given output load. These two regulation processes are applied simultaneously to the power switch control (140) in order to accommodate a wider range of regulated load. Hence in the alternative, for a given load range a smaller frequency range is needed than would be the case if frequency variation alone is used. 
     The regulation control circuit includes both a duty cycle modulator (120) and a frequency modulator (110) each being responsive to an error signal responsive to a differential between an output voltage (191) of the converter and a reference voltage. Each individual modulator has its own transfer function; one transfer function being kHz/volt the other transfer function being %duty cycle/volt. The regulation control circuit output is a rectangular pulse type signal that contains both elements of frequency modulation and duty cycle modulation.
