Abstract: A digital-to-analog converting unit fabricated on a single semiconductor chip comprises a string (91) of resistive elements (R, R/2) coupled between a source of power voltage level (Vdd) and a source of ground voltage level (GND) and an array (92) of switching elements (S2) respectively associated with intermediate nodes each provided between every adjacent two resistive elements, and each of the switching elements is implemented by a parallel combination of an n-channel type component field effect transistor and a p-channel type component field effect transistor even if one of the component field effect transistors of the switching elements near the voltage sources remains off at all times, because the parallel combinations enhances uniformity of pattern on the semiconductor chip, thereby preventing the string of the resistive elements from irregularity of sheet resistance.

Abstract: In order to provide for a mobile communication network of a cellular type a transmission power control system capable of keeping a signal quality constant, an average bit error rate y is measured on a receiving side in connection with a communication channel being in use (step 100). If the average bit error rate y is not greater than a first rate threshold value LV1, transmission power is decreased by a predetermined amount on a transmitting side (step 102). If the average bit error rate y is not less than a second rate threshold value LV2 which is greater than the first rate threshold value LV1 (step 103), the transmission power is increased by the predetermined amount on the transmitting side (step 104). Preferably, an average reception level is additionally measured to adjust the transmission power when the bit error rate is less or greater than the first or the second rate threshold value. The first and/or the second rate threshold value is adaptively adjusted by counting the number of times by which the bit error rate exceeds a predetermined maximum allowable rate. It is possible to use an average carrier to interference ratio with threshold ratio values substituted for the threshold rate values and with a predetermined minimum allowable ratio used.

Abstract: A new interpretation system receives a low resolution log and a high resolution log from a well logging tool that is disposed in a wellbore which traverses a highly laminated formation and generates an output record medium which clearly illustrates and quantifies each layer of the plurality of layers of the laminated formation. In response to receipt of the low and high resolution logs, the new interpretation system generates a rectangular deconvolved log. The rectangular deconvolved log is generated by first selecting a plurality of modes or possible formation types from a histogram. Each of the plurality of modes are then solved, in a least squares sense, by minimizing the sum, over a particular depth interval in the wellbore, of the square of the residual between the tool measurement and the reconstructed log, a calculation which is equivalent to solving a system of N equations and N unknowns. A basis function is determined for each mode, and the rectangular deconvolved log is defined to be the sum of the basis function for each mode multiplied by the calculated value of the associated mode derived from the solution of the N equations and N unknowns. The rectangular deconvolved log is subsequently convolved with a vertical response function of the well logging tool thereby producing a reconstructed log. The reconstructed log undergoes interactive refinement producing a refined rectangular deconvolved log. If no further refinement is needed, a volumetric analysis is performed on the refined rectangular deconvolved log to produce an output record medium which clearly illustrates and quantifies each layer of the plurality of layers of the laminated formation traversed by the wellbore.

Abstract: An automatic coil winder provided with a turret having a rotation axle for carrying a bobbin and a motor for rotating this rotation axle, and provided with a nozzle for supplying wire to the bobbin, further comprises a mechanism for rotating the turret and a mechanism for fixing the turret in a predetermined rotation position. The rotation axis of the bobbin can therefore be inclined depending on the projection direction of a terminal pin on the bobbin, and the tying of the wire around the pin can be easily accomplished. By providing a displacement mechanism which can displace the turret in three dimensions, it is easy to adapt to operations other than winding such as soldering wire to the terminal pin or taping it to the bobbin, and the entire series of coil manufacturing processes can be automated. Further by linking a tiepin, to which the wire is temporarily attached, to the turret via a link mechanism which can be freely engaged and disengaged, the tying of the wire to the bobbin terminal pin can be performed efficiently.
