Filed: 1995-06-14
Abstract: PURPOSE: To obtain a phase synchronizing circuit having a hysteresis comparator used for detecting an unnecessary section at the time of a pull-in and capable of executing high speed operation. CONSTITUTION: A multiplication phase comparator 2 detects a phase difference between an input signal from an input terminal 1 and an output signal sent from a switching circuit 11 to an output terminal 8 and outputs a phase difference signal indicating the phase difference.

Title: Power control method at time of call capture in cdma mobile communication system
Inventor: ULRICH FABEA
IPC: H04W28/04
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To keep constant the closed loop of a mobile station by starting a closed loop power control algorithm when the normal decoding of a preamble signal is confirmed. SOLUTION: A nominal signal/interference ratio(SIR) threshold and a nominal maximum allowable bit error rate(BER) threshold are provided to a detector 6. Closed loop power control increase is set to a fixed value and the mobile station increases transmission power by 0.1 dB per power control group. When the SIR is smaller than the SIR threshold or the current transmission power is less than maximum transmission power, power control increase is set to increase for 0.1 dB and a power control bit is sent to the mobile station. When the SIR value is larger than the SIR threshold or the current transmission power is more than maximum transmission power, on the other hand, the power control bit is sent to the mobile station and the closed loop power control is not contributed to the increase or decrease of transmission power at the mobile station in average. When a preamble frame is decoded without error, the closed loop power control algorithm is started.

Title: Heat exchanger with fins
Inventor: ADACHI MASAAKI
IPC: F25D21/00
Filed: 1984-07-16
Abstract: PURPOSE:To remarkably prolong the driving time until the spaces between fins are blocked with frost layers by forming fin groups by disposing fins cur and raises so that the air inlet and portion has concave and convex portions alternately in the step direction. CONSTITUTION:In the air inlet portions of fin groups 9 and 8, respective fins are cut out ot alternately have concave portions 10 and convex poritons 11 in a direction perpendicular to the air stream, that is, a step direction, and in a direction parallel to the air stream, respectively. Since in the air inlet portions of the fin groups 7 and 8 and fin intervals in the pipe axial direction are widened at every step the spaces between the fins are blocked with frost layer 12 at the frosting time, and hence the driving time until defrosting is required, can be remarkably prolonged. Further, the amount of frost accumulated in resepctive fins 7 and 8 substantially become the same. Hence, the time required for defrosting are substantailly the same in respective fins 7 and 8. Thus, the defrosting efficiency is improved. Further, since the dimensions of concave and convex portions can be made to that these portions have a heat transfer area which is equal to that of a fin having an air inlet portion of a two-way shape, and hence the heat exchange quantity does not decrease.
