Inventor: YANO TAKASHI
IPC: H04J13/00
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To stably maintain the synchronization even under an environment where many reflected waves arrive. SOLUTION: A matched filter 101 receives a received signal, where correlation with a spread code from an spread code generator 108 is conducted and outputs an inversely spread signal. A delay profile detection section 102 receiving the inversely spread signal outputs a delay profile a(n), which is given to a delay profile average section 103, where a time averaged delay profile Ave (|a(n)|2) for each timing (n) can be obtained. A data symbol detection section 104 uses the a(n) and the Ave (|a(n)|2) to apply RAKE synthesis to the inversely spread signal. A representative path timing calculation section 105 uses the a(n) and the Ave (|a(n)|2) to output the representative path timing value such as power weight of a path to control the spread code generator 108 via a loop filter 106 and a clock control section 107.

Title: Detector for bnzs code error
Inventor: KOBAYASHI KOUICHI
IPC: H03M5/16
Filed: 1982-04-05
Abstract: PURPOSE:To detect a BnZS code error without requiring a timing extraction circuit by means of a circuit in small scale. CONSTITUTION:A pattern detection circuit 9 comprises AND gates. An output signal of a conversion circuit 7 is inputted to the gates to prevent malfunction at the point of time of change. When a bipolar signal is a VBV, it is discriminated as a zero replacing pattern, is not regarded as a code error. Waveforms a-g correspond to a-g of the block diagram. The waveform (a) at t=4-10 is the zero replacement pattern with B6ZS codes. The bipolar error is detected at t=6-7,9-10 as shown in the waveform (c). Since an FF8 is cleared at t=10 with an output signal of the circuit 9, no BnZS code error takes place. Further, the error pulse is not cleared like the waveform (a) at t=12-13, and the B6ZS code error like the waveform (g) at t=17-19 is detected. Thus, the device is operated satisfactorily as the error detector.

IPC: H01L21/8242
Filed: 1987-03-11
Abstract: PURPOSE:To obtain the constant voltage having a desired level and high accuracy by obtaining a constant potential difference to obtain the constant current based on said potential difference and then obtaining the constant voltage based on said constant current. CONSTITUTION:At a constant potential difference generating part 5, the drain and gate electrodes of an nMOSFET connected in common to each other are connected to a power supply terminal 9 and also to a ground power supply terminal 10 through a resistor 8. The resistance value of the resistor 8 is set at such a level where an FET 4 is actuated in a state set before and after a weakly inverted state is changed to an intensively inverted state. In such a way, the voltage VCC higher than the threshold voltage of the FET 4 is supplied to the terminal 9. Thus, the FET 4 is saturated and the voltage approximately equal to a threshold level is obtained between the gate and the source. This voltage is supplied to a constant current generating part 6 so that the part 6 serves as a constant current source. A constant voltage generating load part 7 outputs the desired reference voltage V0 to a reference voltage output terminal 13 based on the constant current supplied from the part 6.

Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To provide an electrostatic spray coating system comprising a measuring device to measure the present value of high voltage of at least one high voltage electrode to charge a paint electrostatically. SOLUTION: A control voltage, that is an input voltage U2, is measured on the input of a transformer circuit 4, 6 and multiplied by a multiplication factor of the transformer circuit 4, 6 and thereby forms a theoretical value of the high voltage on the high voltage electrode 8. This theoretical value deviates from the actual value of the electrode high voltage U2 by the amount of the internal voltage drop generated at the voltage transformer circuit 4, 6 when a current flow through the transformer circuit 4, 6. This internal voltage drop is determined by calculation 32, 34 as a function of the electrode current I2 and is subtracted from the theoretical value 38 in order to generate a signal voltage 32 corresponding to the actual value of the electrode high voltage U2.  This signal voltage 32 is subtracted from a target voltage value and generates a regulating differential voltage for a controller 44 as a function of the electrode high voltage U2.
