Patent EP-0224379-A3 (EP)
Title: Compensation method to correct thermally induced off-track errors in disc drives
IPC: G11B5/55
Filed: 1986-11-19
Abstract: A thermal test track (- 3) is provided outside the user-accessible area on the disc. A track complete of a known frequency is then written on either side of this thermal test track, preferably half the usual track separate distance away. To develop a thermal compensation constant, the transducer (10) is moved to the thermal test track with no compensation applied. This way, any thermally induced off-track error, which would affect seeks to user-accessible data tracks, will be reflected in the off-track from the nominal position of the thermal test track. The transducer is now moved in a series of defined increments (e.g. 5) smaller than normal track-to-track steps, or "micro-steps", away from the uncompensated position of the thermal track toward one of the tracks written with the known frequency. When the data on the written track to the side of the thermal test track is detected, a note is made of the number of micro-steps the transducer has been moved. The transducer (10) is then micro-stepped incrementally in the opposite direction until the data written on the other side of the thermal test track is detected. A simple comparison of these two micro-step counts will yield the existing thermal shift, which can be converted into a thermal compensation constant for the transducer positioning mechanism by means of a simple look-up table.

Abstract: A gerotor or N(N+1) type pump comprises outer 
and inner lobed rotors 10, 11 defining pumping chambers 
16 and has an inlet port 18 and two outlet ports 19, 
20. Ports 19, 20 are separated from each other by a

is sufficient to ensure that there is always a leakage 
path from the pumping chamber to which the slot opens 
to one or other of the two outlet ports as the slot 
passes the land 22.

Title: Thin film coating method
IPC: B29C65/78
Filed: 1988-02-23
Abstract: In a thin film coating method, tack members are brought close to a surface of a substrate to temporarily tack the forward end portion of a web of thin film to the forward end of the substrate. Compression-bonding rollers are then brought into a tacking position where the forward end portion of the thin film is tacked from a standby position where the compression-bonding rollers do not touch the tack members to make compression-bonding contact with the forward end portion of the tacked thin film after the tack members are moved away from the surface of the substrate. The compression-bonding rollers are then rotated at the tacking position for the double purpose of conveying the substrate and adhering the thin film to the substrate. In this process, the forward end of the substrate is detected to produce a detection signal at a detection position before the substrate is conveyed to the tacking position, the conveyance of the substrate is stopped after the forward end of the substrate has been conveyed from the detection position to the tacking position, and the tack members are brought close to the conveyance passage of the substrate while the forward end of the substrate is being conveyed from the detection position to the tacking position to thereby tack the forward end of the thin film to the surface of the substrate after the forward end of the substrate is stopped at the tacking position. <IMAGE>

Title: Valve device for fluids under pressure
IPC: F16K31/365
Filed: 1988-06-01
Abstract: In a valve device for fluids under pressure, having a diaphragm which is subject to the pressure of the fluid under pressure, it is normal to influence at least one operating parameter by the magnitude of the effective area of the diaphragm which is subjected to the pressure. In this case, the magnitude of the effective area is defined by the dimensions of a support on the housing side. To change the magnitude of the effective area, it is known for the housing part carrying the support on the housing side to be replaced. A wide range of adjustment possibilities for the magnitude of the effective area necessitate a correspondingly wide range of housing parts, with a correspondingly high cost. This cost is reduced by means of the invention. The invention proposes to provide at least one housing insert (1) to support the effective area (12, 15) of the diaphragm (2). <IMAGE>

IPC: F16J15/24
Filed: 1988-06-01
Abstract: The present invention relates to a sealing arrangement for 
sealing a rotary shaft by means of several adjacent ring-type 
packings arranged in a packing box. The disadvantage of known 
arrangements is that, in box-type sealings, only the packing 
rings disposed nearest to the clamping element are clamped 
effectively. In the arrangement of the invention, an inter­
mediate gland (11) is arranged between packing rings (8, 9) 
and said intermediate gland is forced to move to the left 
while the screws (13) are being screwed up. The desired effect 
is achieved by providing the ends of each screw (13) with 
divergent threads (16, 17), which are provided with an unequal 
or equal pitch.
