Abstract: A disk controller for a plurality of disk drives is disclosed. This controller includes a plurality of first memory means (21), the number of which is equal to the number of the disk drives and each of which stores a group number (G i ) representative of a kind of the associated disk drives, and further includes a plurality of sets of second memory means (23,24,25), the number of which is equal to the number of the kinds of the disk drives and each of which stores control parameters used for controlling the associated kind of the disk drives. One of the first memory means is accessed in response to a disk drive selecting signal and one of the sets of second memory means is selected in response to the group number read from the accessed first memory means. The controlled parameters stored in the selected set of second memory means are thereby read out to control the disk drive.

Abstract: The present invention provides an organic nonlinear optical material comprising a benzylidene-aniline derivative having an electron-donating substituent introduced at the 4-position and an electron-accepting substituent introduced at the 4ʹ-position, by following two contrivances: (l) selecting as the conjugated π electronic system a benzylidene-aniline derivative having a large molecular hyperpolarizability and yet a dipole moment as small as those of benzene derivatives, and (2) introducing a molecular alignment-regulating substituent. The centrosymmetry in the bulk state of the material, for example, in the crystal state, is destroyed and the molecular alignment is regulated to such a bulk structure in that the optical nonlinearity possessed by the molecule is effectively utilized. The material shows even a large optical nonlinearity never attained by the conventional techniques. 
     The intermolecular cohesive force due to the π electron interaction between the molecules in the present invention is larger than that between benzene derivatives. Consequently, the material has, compara­tively, a high melting point, a low subliming property, and a low water-absorbing property. In conclusion, a practically invaluable nonlinear optical material having a high durability in the bulk state and an excellent resistance to laser damage can be provided.

Abstract: A vehicle suspension system has a gas-sprung hydraulic strut (6,7) for each of its four wheels (2,3).

A linear potentiometer (26) within each strut (6,7) provides a signal representative of the strut length to an on-board computer (28), which, when it detects a difference in the signal from any strut sensor (26) from a predetermined value, causes a proportional servo-valve (35) to admit hydraulic liquid from the actuator chamber of that strut at a flow rate proportional to the detected difference to return the strut length towards its predetermined value.

IPC: G04G7/02

Abstract: A radio signal controlled clock (62) which decodes time informa­tion in a radio signal (12) and thereby determines the current time. The clock collects and stores radio signal data as soon as a reasonably decodeable radio signal is located, even before the minute boundary of the radio signal's time base has been located. This data is stored and later used for decoding and verifying the digits of the time informa­tion after the minute boundary has been located. Digits are verified using a scoring method which is highly noise tolerant, allowing digits to be decoded and verified even if a single error free digit is never received. In another aspect of the present invention, an internal counter in the clock is periodically resynchronized with the radio signal (12), and the average of the adjustments required for this resynchronization is maintained. When no radio signal is available, or the radio signal is too noisy to be reliably decoded, the average internal counter adjustment value is used to periodically adjust the internal counter - and thereby helps to keep the clock's internal counter as closely synchronized with the radio signal's time bases as possible when the radio signal is not available or not usable.

Abstract: The device comprises essentially a body (1) or shaped piece of cylindrical form and of a circular or polygonal cross section, comprising tubular cavities (2 - 5) of different diameters for receiving the bars (B) to be machined of different diameters and/or profiles. The tu­bular cavities (2 - 5) can comprise longitudinal distri­bution channels (11) for feeding oil under pressure to the bar (B) to be machined. The cylindrical body (1) further comprises indexing grooves (23) at its external periphery, means of distribution of oil (13) at the rear part of the device, an oil extractor (16) located at the front part of the device and cavities (7, 8) permitting the return of the oil to a hydraulic group (20). Rein­forcing ribs (10) are provided between the tubular cavi­ties (2 - 5) and between the latter and a mantle of the cylindrical body (1) so that the latter has a great mo­ment of inertia which ensures a good stability of the device. The tubular cavities (2 - 5) may comprise tubes (18) aligned along the longitudinal axis of the cavities and rotating freely with play in these tubular cavities (2 - 5). These tubes (18) are the proper guiding tubes and they protect the tubular cavities (2 - 5) against the damages which could be caused by the fast rotating bars (B) to be machined. These tubes (18) permit also to create a double hydrodynamic bearing permitting to im­part very great speeds of rotation to the bars (B) to be machined.
