Patent EP-0728909-A2 (EP)
Inventor: BARR JOHN D
IPC: E21B47/18
Filed: 1996-02-13
Abstract: A steerable rotary drilling system has a bottom hole assembly which includes, in addition to the drill bit, a modulated bias unit (10) and a control unit (9), the bias unit comprising a number of hydraulic actuators (13) around the periphery of the unit, each having a movable thrust member which is hydraulically displaceable outwardly for engagement with the formation of the borehole being drilled. Each actuator can be connected, through a control valve (138, 136), to a source of drilling fluid under pressure and the operation of the valve is controlled by the control unit so as to modulate the fluid pressure supplied to the actuators as the bias unit rotates. If the control valve (138, 136) is operated in synchronism with rotation of the bias unit the thrust members impart a lateral bias to the bias unit, and hence to the drill bit, to control the direction of drilling. Pulses transmitted through the drilling fluid as a result of operation of the bias unit (10) are detected and interpreted at the surface, or at a different location downhole, to obtain information regarding the operation of the bias unit or other parts of the bottom hole assembly. Data signals from downhole sensors (27) may be arranged to modify the control and operation of the bias unit (10) in such manner that the data is encoded as pulses generated in the drilling fluid by the bias unit.

Abstract: The present invention provides for selective droplet dispersion. The selective droplet dispersion technique of the present invention is used to optimize image quality from a continuous ink jet printer. Initially, a pixel to be printed is identified, and then placement of droplets within the pixel to be printed is selected to optimize image quality. The selection can be unconditional, wherein the placement of droplets is not dependent on neighboring pixels. Such selection includes printing first or last available droplets, or centering the droplets within the pixel to be printed. The selection can also be conditional, wherein placement of droplets is dependent on surrounding pixels. Such selection includes providing data from at least one surrounding pixel relative to the identified pixel and using the surrounding pixel data to select droplet placement within the identified pixel.

Abstract: A method and apparatus for simultaneous voice/data transmission of signals through a single communications channel wherein the transmitted voice and data signal quality is greatly enhanced over current practice. A time-varying stream of coded voice and data signals is simultaneously transmitted and the sequence of transmitted data signals is determined only after receiving data signals for a predetermined period of time. The received signals are buffered and a received coded data signal sequence is compared to a predetermined plurality of permissible coded data signal sequences to correlate the received coded data signal sequence with the particular permissible coded signal sequence with which the data signal was coded prior to transmission. The correlated data signal sequence is then separated from the combined voice and data signal to recover the coded voice signal. The recovered voice signal and correlated data signal sequence are thereafter decoded to recover the voice and data signals that were received and coded by the transmitter. Timing and equalization of the receiver are also maintained during intervals in which no data signals are transmitted, i.e. "voice only" mode, by generating in such intervals a data tracking signal for combination with the coded voice signal and transmission of the resulting combined signal to the receiver.

Abstract: The circuit (20) comprises a reference potential-generation circuit (21), a differential amplifier (22), and a feedback circuit (23). The reference potential-generation circuit (21) generates a reference potential (VR) substantially equal to the upper limit of that high level of each of the bit lines (13) which is assumed at the time of writing. The differential amplifier (22) has an input terminal to be supplied with the reference potential (VR). A write voltage (SW or Vpp) serving as an operation voltage is applied to the amplifier (22). The feedback circuit (23) is connected between the other input terminal and output terminal of the differential amplifier (22). The feedback circuit (23) generates, under the control of the differential amplifier (22), a write control voltage (VA) higher than the reference potential (VR) by the threshold voltage of the writing transistor (15), and applies the write control voltage (VA) to the gate of the writing transistor (15). Also, the feedback circuit (23) feeds a voltage (VB) obtained by reducing the write control voltage (VA), back to the other input terminal of the differential amplifier (22).

Abstract: To restrict a fitting length of an inserting side tubular member such as a corrugate tube into a receiving side tubular member having a flexible portion such as a rubber boot when the inserting and receiving side tubular members are connected. 
     Projections (stopper means) 16 are formed on the inner surface of a fitting end portion 13. When a corrugate tube 20 is fitted into the fitting end portion 13, a leading end 20A thereof comes into contact with the projections 16, thereby restricting any further insertion of the corrugate tube 20. This prevents the entry of the corrugate tube 20 into the flexible portion 12. Accordingly, there is no likelihood that the smooth deformation of the flexible portion 12 is hindered by the entry of the corrugate tube 20 into the flexible portion 12. Further, since there is no need for a consideration as to an excessive insertion of the corrugate tube 20, the connection can easily be performed.

Abstract: In a TDMA cellular mobile communications system the radio interface between a mobile station and a base station consists of traffic frames which include several time slots in which in one time slot of an uplink direction frame the mobile stations can transmit in an access burst a request to the network to be assigned a radio connection for traffic. A repeater is added in the system through which the radio connection between the base station and the mobile station can pass, if necessary. The repeater converts the carrier wave frequency used by the base station to the carrier wave frequency used by the mobile station, and the carrier wave frequency used by the mobile station to the carrier wave frequency used by the base station. The repeater adds its own burst to the access burst of the mobile station, the said burst including the information which identifies the repeater.
