Inventor: MAYES MICHAEL KEITH
IPC: H03K17/10
Filed: 1991-11-06
Abstract: A logic level control circuit prevents impact ionization in a CMOS integrated circuit. The substrate bias voltage of the CMOS integrated circuit is detected by the control circuit and a control signal is provided in response to the detected bias voltage. The bias voltage can be zero volts or negative five volts. If the bias voltage is zero volts, the control signal is a logic level one. If the bias voltage is negative five volts, the control signal is a logic level zero. The control signal is applied to the gate of at least one other controlled device on the integrated circuit for turning that controlled device on and off. The controlled device coupled to a further CMOS device and turning the controlled device on and off prevents impact ionization by allowing the controlled device to alternately divide a voltage level with the further CMOS device or be effectively removed from the circuit.

Abstract: A method and apparatus are disclosed for controlling the cross slope angle cut by the blade of an articulated frame motorgrader (100) being steered through a turn, operated in a straight frame mode, in a crabbed steering position and/or traveling in a non-horizontal plane. The blade angle is sensed and controlled such that the sensed blade angle is maintained substantially equal to a calculated blade angle. In a first embodiment, the blade angle calculation is performed using the equation: 
tan BS = (sin  τ′ )(tan R) + (cos  τ′ )(tan CS) where BS is the required blade slope angle of said blade (114) relative to horizontal;  τ′  is a rotational angle of the blade with respect to the blade's direction of travel (112) projected into horizontal; R is an angle between the blade's direction of travel (112) and horizontal; and CS is the desired cross slope angle which is entered by an operator of the motorgrader (100). In a further embodiment, the blade angle calculation is performed using the equation: 
tan BS = (sin  τ˝ )(tan R′) + (cos  τ˝ )(tan CS) where BS is the required blade slope angle of the blade (114) relative to horizontal;  τ˝  is the rotational angle of the blade with respect to the blade's direction of travel (112) projected into horizontal with the lateral slope angle of the front steering unit (106) set equal to zero; R′ is an angle between horizontal and the direction of travel (112) of the blade with the lateral slope angle of the front steering unit (106) set equal to zero; and CS is the desired cross slope angle.

Abstract: A camera shake correcting apparatus comprises a variable angular prism (7), a microcomputer (20) serving as a means for driving the variable angular prism (7), actuators (6) and (15), vertical angle sensors (8) and (16), angular velocity sensors (1) and (10) for detecting an angular velocity caused by a camera shake, and damping coils (26) and (32). The variable angular prism (7) is driven by a signal which results from subtracting detected results of the vertical angle sensors (8), (16) and the angular velocity sensors (1), (10) from detected results of the angular velocity sensors (1), (10). The position signal from the vertical angle sensor is subtracted from the detected signal obtained from the angular velocity sensor when camera shake occurs. The prism is driven by a signal which results from subtracting rotational angular velocity signals detected by a damping coil from the subtracted result. Therefore, a nonlinearity of the prism can be alleviated, i.e., the prism can be driven smoothly. Also, the phase margin of the servo characteristic can be increased. Thus, the camera shake correcting apparatus can be made resistant to the fluctuation of elements in its mass-production and a dependency of temperature characteristics.

Abstract: A system for pattern based text translation using translation patterns for machine translation that can easily be created and efficiently retrieved by a user is provided. A translation pattern comprises a source language pattern (18A), a variable (18B) that replaces this source language pattern with one character, and a target language pattern (18C) as a translation sentence corresponding to said source language pattern. In addition, the source language pattern includes a nest in which another source language pattern can be nested as a variable. A translation sentence is generated based on the result of matching between an input text sentence and the translation pattern. If there is no matching translation pattern, translation is performed by a general machine translation apparatus based on a grammar. Because a nested structure is employed, the user can create a number of translation patterns based on a specific method of expression, and can easily perform customisation. Furthermore, fast pattern matching becomes possible by creating an index with a tree structure.

Abstract: In a noise controller which forms a noise cancelling sound having a phase opposite to and a sound pressure equal to those of a noise infiltrating into a closed space, any deviation in its transfer characteristics from the initial equalization is easily checked and judged owing to the provision of an adaptive filter 10 which automatically varies the filter coefficient and forms a cancelling signal for forming a cancelling sound, a coefficient updating means 11 which updates the filter coefficient based on an error signal after the noise has been cancelled, a second simulated transfer characteristics compensation means 13 which forms the initial equalization by simulating transfer characteristics of a transmission path via the space in which the noise is to be cancelled and forms a reproduced reference signal, a white noise generating means 15 which generates white noise to check the initial equalization, and an initial equalization judging means 18 which judges the accuracy of the initial equalization based on a ratio (S/N) of the reproduced reference signal obtained from white noise to the error signal. A change in the conditions for cancelling noise is detected in the closed space, and any deviation from the initial equalization is judged.

Abstract: Maximum operating speed is achieved in an array of memory cells (10) by performing both read and write operations within a single memory cycle. As outgoing data are read from the memory cells, incoming data are stored immediately in those cells. Reduced power consumption is achieved in such memories by preventing the occurrence of a write operation if the value of a bit to be written to a memory cell is the same as the value of the bit currently stored in that memory cell. More particularly, the result of a read operation on a particular memory cell is compared (e.g. in an EX-OR gate in 12) with the data value to be written to that cell to determine whether a subsequent write operation is required. If the value in the cell equals the value to be written, the write operation is not performed.

Abstract: A disk player has a magazine for storing disks and a disk transport mechanism transporting a selected disk between four positions including an ejection position, a load position, a playback position, and an initial store position which lie in a single plane. The selected disk is carried upon a tray from the ejection position to the load position where the selected disk is partially removed from the tray to the playback position above a disk reader. The partial removal of the disk from the tray to the load position provides a required clearance for the disk reader permitting a tray length to be minimized. The magazine accepts a plurality of disks. An alignment mechanism provides relative movement between the magazine and a plane of transport of the disk transport mechanism permitting a selected disk to be inserted or removed from the magazine at the initial store position. The disk reader is positioned to read the selected disk overlapping disks stored in the magazine resulting in a smaller disk player size. An embodiment of the invention transports the disks upon carriages accepted in the magazine and a lifter mechanism pivots apart disks in the magazine to allow sufficient clearance for the reading of a selected disk.

Abstract: A rotary actuator disk drive uses substantially identical dual-element inductive write/magnetoresistive read transducers for both the top (11) and bottom (12) disk surfaces. There is no requirement that the read elements (91,95) be mechanically offset from the write elements (92,96), as is typically the case in rotary actuator disk drives due to the head-to-track skew caused by the inherent nonlinear path of the heads across the data tracks. The transducers are supported on the trailing ends of the head carrier (13,17,90,94)  in such a manner that the geometric centers of the read and write elements are aligned without any mechanical offset (d). The sense current (108) for the magnetoresistive elements is provided with opposite polarity to the elements (120,122) on the top and bottom disk surfaces to shift the magnetic centers (110) of the top and bottom read elements in opposite directions relative to their geometric centers (104). The amount and direction of the magnetic shift is such that the read elements are effectively offset from their respective write elements so that the skew caused by the rotary actuator has minimal effect on alignment of the read and write elements with the data tracks.
