Patent EP-0419909-A2 (EP)
Inventor: GUNJI SHIZUKA C O INTELLECTUAL
IPC: G06F1/26
Filed: 1990-09-06
Abstract: A computer system is provided with both an auto power off mode and a resume mode. In the computer system, the motor off command (MOC) for an HDD (42) is kept effective from the time when the system is turned on to the time when the HDD (42) is accessed. During the interval, therefore, no power is supplied to the HDD (42). When the HDD (42) has just been accessed, the motor off command (MOC) is made ineffective, to thereby supply power to the HDD (42). When the power supply to the HDD (42) is started, with the system in the resume mode, the CPU (11) permits data processing to be performed from the state immediately before the power supply is stopped.

Abstract: In an automatic transmission 16, clutch-to-clutch powered downshifting is controlled by filling the on-coming clutch C1-C5 at a low pressure while ramping down the off-going clutch pressure Pioff until turbine speed is pulled up due to off-going clutch slippage, and then increasing the off-going pressure stepwise to compensate the change from static to dynamic coefficients of friction. Then the on-coming pressure Pion is gradually ramped up and a closed-loop profile control period starts wherein the slip of the on-coming clutch C1-C5 is measured and controlled to a slip profile by controlling the off-going clutch pressure Pioff. When synchronization of the on-coming clutch C1-C5 is first detected, a closed-loop sync control period starts wherein the off-going pressure Pioff is controlled to minimize the slip and the on-coming pressure Pion is ramped up at a steeper rate to begin clutch engagement during the sync control period.

Abstract: A power conversion apparatus for providing AC to DC to AC power conversion which is particularly adapted for use with single phase uninterruptable power supply systems. By having the power flow completely unidirectional from AC line to load, only four active switches are required to provide independent control of the input and output currents, a common neutral connection, line connection, sinusoidal input currents independent to load currents, as well as battery charge and discharge regulation. In an embodiment where low voltage battery and resonant link operation is desired, an additional switch is utilised. The apparatus utilises a rectifier bridge, a DC power source inverter having gate controllable switching devices connected in a bridge configuration and control means for controlling the switching of the controllable switching devices to provide AC output at a selected frequency, a common neutral line being utilised which is common to one of the input terminals and one of the output terminals of the apparatus and also to one output node of the inverter bridge configuration.

Abstract: A vehicle roof is indicated, especially one intended for trucks or the like, on which a cover can be opened out about two axes running transversely to the longitudinal axis of the vehicle and an opening device in relation to a frame, the frame being insertable in a roof opening provided in the fixed roof face of the vehicle. In order to form an emergency exit hatch, an emergency unlocking device is provided which separates the cover from the frame in the area of both swivel bearings by means of a common operating device, which can be operated from inside the vehicle or from outside. In one embodiment the emergency unlocking device separates the swivel bearing with the opening device from the frame, whilst in another embodiment the emergency unlocking device and the swivel bearings on the frame separate. The emergency unlocking devices are in this case designed in such a way that separation in both opposing swivel bearings of the cover can essentially be performed simultaneously and only one operating movement has to be performed of the emergency locking device which is provided on one swivel bearing area. The transmission of the movement for the other swivel bearing is performed by a carrier device in the form of a draw wire or a Bowden cable. As an anti-theft safeguard an additional locking device can also be provided which, where necessary, can be coupled to a central locking system of the vehicle. The emergency unlocking device can be constructed in such a way that it can be released either from outside or from inside by applying a compressive force or a tensile force in order to separate the swivel bearing of the frame. Operation of the operating handle of the emergency unlocking device can also be performed by a rotary movement.

Abstract: The present invention comprises a method and apparatus for simultaneously drilling and casing a wellbore. More specifically, the apparatus comprises and outer conduit string (70) containing an inner drill string (50) carrying a bit (64) capable of drilling a wellbore of greater diameter than the outer string. The drill string (50) may be adapted to drill a nonlinear wellbore (20) by offsetting the drill bit from the longitudinal axis of the outer string, and the drill bit (64) is preferably retractable to permit withdrawal of the drill string after the wellbore is completed, leaving the outer string (70) of casing or liner in place. The wellbore is drilled by rotating the drill bit and advancing the drill string by pushing from the surface, and the outer string is advanced by being pulled along by the drill string.

IPC: G01F1/66
Filed: 1991-06-27
Abstract: The invention relates to a method and a device for determining the beat frequency of intensity-modulated pulse-shaped signals, particularly of scattered-light signals triggered by moving particles and modulated by spatially changing light/dark effects. Signals of this type are triggered in optical velocimeters, particularly in laser Doppler anemometers, by particles which emit scattered light when crossing through a spatially periodic field of light/dark stripes. When the stripe spacing of the light/dark field is known, the speed of the particle perpendicular to the stripe spacing can be determined from the beat frequency of the signal. To be able to determine the beat frequency with a high measuring rate within a wide frequency range, it is proposed according to the invention that a sampling process is initiated at the signal start and is stopped at the signal end and that during the sampling process the time-dependent signal intensity is measured in a timing pattern with a sampling frequency which decreases with time. The sampling frequency is preferably halved in successive time intervals and the length of successive time intervals is doubled. The sequence of measurement values determined in this manner is evaluated, for example by a fast Fourier transformation, for determining the beat frequency. A measurement value sequence corresponding to an equidistant subpattern is expediently used for the evaluation, the pattern spacing corresponding to the sampling frequency in the vicinity of the signal end. Provisions for accurate signal detection are made in the interests of precise measurement and a high measuring rate.

Abstract: An image area determining apparatus acquires a multi-value image to determine to which one of a picture area and a character area an image signal of the multi-value image belongs. A density detecting unit detects whether or not a density value of the multi-value image is within a range between two preset density threshold values. A density variation amount detecting unit detects whether or not a variation amount of the density value of the multi-value image is less than a preset density variation threshold value. The determining apparatus determines that the multi-value image is related to a picture area when the density value of the received multi-value image is within the range between the two density threshold values and the density value variation amount of the multi-value image is less than the density variation threshold value.

Abstract: In an image encoding apparatus, conversion data obtained by converting image information onto a frequency region, and corresponding to several frames are parallelly output using a one-frame period delay circuit (34a...34d). The parallelly output conversion data are quantized by a quantization circuit (32a...32e) and a data amount to be obtained when the quantized data are encoded is obtained by a variable-length coding circuit (40a...40e). The data amount information is input to a coefficient operation circuit (44a...44d) for determining a quantization step of the next stage. Conversion data quantized according to an output from the coefficient operation circuit are encoded, and the encoded data are output.
