Title: Measuring method and device using sonde with measuring pad
Inventor: PASUKARU PANTA
IPC: E21B47/026
Filed: 1982-09-08
Abstract: Dip measurements and investigation of geological formations traversed by a deviated borehole is carried out by means of an apparatus comprising a measuring sonde and a cartridge connected to a cable. The sonde carries four measuring pads regularly distributed by means of articulated arms which keep the pads parallel to the axis of the sonde. The opposite arms are forced to stay symmetrical in relation to the sonde. The sonde is connected to the cartridge so that its axis can depart angularly from the axis of the cartridge, enabling the latter to rest on the borehole wall. The pads have a length smaller than twice the transverse dimension D of the sonde.

Title: Qam demodulator
Inventor: KAWANAKA ZENICHI
IPC: H04L27/38
Filed: 1995-05-31
Abstract: PURPOSE: To demodulate a modulating signal by detecting a synchronization symbol from a position of the symbol at which the result of product sum operation between the amplitude error and the phase error has a minimum value so as to correct the phase thereby conducting phase correction based on detection of accurate synchronization. CONSTITUTION: A regeneration circuit regenerates a symbol signal. An AGC circuit adjusts the gain of the symbol signal. When S-sets of synchronization symbols are in existence for a prescribed period and a phase angle error detection circuit obtains an error of each of S-sets of consecutive synchronization symbols with respect to a phase, the phase angle detection circuit uses a product sum computing element 21e to obtain components I(T) and Q(T) predicted from 2nd and succeeding synchronization symbols with sinα and cosαbeing coefficients calculated from a difference α from a phase angle of each one- preceding synchronization symbol. Then an error of a phase angle is obtained by comparing the components I(T) and Q(T) predicted from the 2nd and succeeding synchronization symbols. with the components I(T) and Q(T) of the recovered symbol signal.

When opening a drain valve 11 under this condition, the flooding portion a 1  is drained by pressure difference between a lower basin and a runner 4 because the water-level of the lower basin is higher than the runner 4. When the runner is exposed to air, the runner is revolution started, and a motor for driving a pump water turbine is inserted in parallel with the system after the number of revolution reaches the number of prescribed revolution. When the feed and exhaust pipe 8 is opened to the atmosphere and the feed and exhaust valve 9 is slowly opened, water flows around the runner while passing a portion C, and flowing-in water is pushed to an outer circumference of the runner by centrifugal force. Thus, a void portion b is completely flooded, a guide vane 2 is opened and the pump is operated.
