Patent GB-2302982-A (GB)
Title: Data recording/reproducing apparatus employing read-after-write system
Inventor: ISHIBASHI HIROSHI
IPC: G11B20/12
Filed: 1996-06-28
Abstract: A recording apparatus, eg a digital audio tape recorder or a data storage device includes means for ensuring the correctness of parity data. An ECC unit 23 appends parity data for error correction to recording data and transmits the resulting data to recording heads Hw1, Hw2, while also storing the parity data in a RAM 61 for subsequent comparison with reproduced parity data. The recording and parity data are reproduced from a magnetic tape 32 by magnetic heads Hr1, Hr2 and supplied to a sub-code separation unit 45. A syndrome detection unit 62 detects the number of error corrections performed by parity by an error correction unit 46. A system controller 63 compares the number of times of error corrections to a threshold value and compares the parity data read out from the RAM 61 with the parity data from the sub-code separation unit 45 in order to detect if the recording data has been recorded correctly. If the recording data has not been recorded correctly, the system controller controls a recording/reproducing unit 30 for re-recording the same recording data.

Title: Method of locking rotation and tensioning coupling using such
Inventor: LUDKIN BASIL
IPC: B60P7/08
Filed: 1997-01-31
Abstract: Rotation of an inner body, e.g. a hollow cylinder 24, is allowed in one direction but prevented in the other, within an outer sleeve 23 by a spring 30 between them and cooperating with them. A tensioning coupling comprises two cylindrical bodies, each being provided with a respective connector and being arranged for linear movement with respect to each other. The first body comprises a threaded rod 22 and the outer sleeve 23 spaced apart therefrom, the second body comprising the hollow cylinder threadedly engaging the rod 22. The spring 30 engaging around the outer surface of the cylinder 24, has its ends 31 located in apertures 33 of the sleeve 23, one aperture retaining the end 31 fixed and the other being elongate to allow end movement. This allows for spring diameter to increase in one rotational direction to allow rotation of the cylinder 24 in the sleeve 23, e.g. for increasing tension in the coupling.

Title: Adaptive threshold circuit
Inventor: ISHIKAWA NOBUHIRO
IPC: G01B7/00
Filed: 1997-10-02
Abstract: The amplitude detected output from a contact probe (figure 1) using a piezoelectric oscillator contains a high frequency component S2 and a low frequency wave S1 superimposed on a DC signal S0 and a DC level transition signal S3 (figure 3) caused by contact. An adaptive threshold for the contact detecting comparator 23 is produced by a low pass filter 21 followed by a voltage divider or multiplier 22. The low pass filter removes the high frequency signal, while the divider 22 provides an offset that follows the low frequency wave S1, thus allowing reliable detection of probe contact and production of a touch trigger signal despite the presence of noise and drift. The thresholding circuit may be applied to other transducers, such as pressure or acceleration sensors.

Filed: 1997-11-13
Abstract: A phase locked loop includes a comparator 50, Fig 3 and a VCO 54 having a multi-stage oscillator 68, Fig 4 and a combinational logic stage 70. The comparator is responsive to an input clock 56 and a VCO comparison clock 62 and produces an output 60 to control the VCO 54. The multi-stage oscillator 68 oscillates at a VCO clock frequency during a steady state and provides a plurality of clock phases at the VCO clock frequency. The combinational logic stage 70 is responsive to at least some of the clock phases and combines the clock phases to provide an output clock frequency that is a multiple of the input clock frequency. A frequency divider 63 may be provided. A further aspect relates to the VCO and a method for multiplying an input clock frequency including applying an input clock to a delay chain, developing a plurality of phase shifted clocks by tapping into the delay chain, and combining the plurality of phase shifted clocks in combinational logic stage 70 to produce an output clock having a frequency that is a multiple of the input clock frequency. Examples of the multi-stage oscillator 68 are described (Figs 5, 8, 12, 15a and 15b). Also the combinational logic stage 70 is described in detail (Figs 6a, 6b, 9a-9e, 12 and 13).

Title: A method of modelling pore distribution in a porous sample of variable porosity
Inventor: DERUYTER CHRISTIAN
IPC: G09B23/40
Filed: 1997-11-13
Abstract: The invention relates to a method of modelling the pore distribution of a porous sample of variable porosity which can be used to conduct laboratory studies on the behaviour of the modelled medium with respect to fluids. The porosity of the porous medium is modelled along one or more sectioned surfaces by means of networks (R) of inter-connected channels (C), the nodes of which represent pores (P), the size of these channels translating physical properties of the medium and being selected from one or more discrete distributions of channel sizes. In order to model the porosity of a heterogeneous sample having zones of very differing porosity, several discrete channel distributions are used by preference, these distributions being disjoint or not, so that one is used to model zones of low permeability and the other zones of higher permeability. The geometric model produced is converted into a physical model from a previously constructed geometric model using a controlled laser, for example, to form on a material which reacts to light a network of channels translating the porosity of the sample along one or more sectioned surfaces and join them to one another. Application in particular to modelling porous rock samples taken in particular from hydrocarbon reservoirs.
