Provided is a phase-locked loop frequency synthesizer, including: a reference oscillator; a voltage controlled oscillator; a variable frequency divider that divides the high frequency signal in frequency to output a feedback signal; a phase comparator that compares the reference signal and the feedback signal with each other to output a phase comparison signal; a loop filter that outputs a control signal of the voltage controlled oscillator based on the phase comparison signal; and a frequency/phase control circuit that generates frequency division number control data in synchronism with any one of the feedback signal and the reference signal based on setting data which is input from an external to give an output frequency and setting data which is input from the external to give a phase to the reference signal, to thereby output the frequency division number control data to the variable frequency divider.

摘要:
When transmitting an RF signal for power supply or a pulse signal for data transmission, amplification is made in such a manner that the peak power of the RF signal becomes greater than the peak power of the pulse signal. Thus transmitting the RF signal with the greater peak power enables charging of a capacitor 23 of noncontact wireless communication equipment 2 even if the distance to the noncontact wireless communication equipment 2 is long.

A play toy system using a remote-controlled traveling toy, which enables the remote-controlled traveling toy to make a movement that is more unexpected than before. The remote-controlled traveling toy includes one front wheel and two rear wheels. The traveling toy is remotely controlled by remote control signals and is so constructed as to travel on a traveling surface of a play board. The diameter sizes of the two rear wheels 7 and 9 are different. With one front wheel and two rear wheels having a different diameter, the remote-controlled traveling toy can move more unexpectedly than anyone has ever experienced, according to the state of the traveling surface of the play board.

A quadrant deciding section decides the quadrant to which a received signal belongs based on a baseband signal. A rotation projector rotates the received signal and projects the rotated signal to a straight line that intersects orthogonally at the origin with a straight line that bisects the decided quadrant. An integrator integrates the signal after the projection. A one-bit quantizer quantizes the integration result by deciding the sign of the integration result. A delay circuit delays the quantized signal by a predetermined time. An adder adds the decision result and the quantized signal modulo the phase 2π. A low-pass filter sequentially latches phase values after the addition with internal shift registers, converts the phase value to a prescribed specific value when the phase values that cross over 2π exist in the whole data within the registers, and averages the phase values.

A soft-magnetic FeCo based target material is provided which has a high saturation magnetic flux density and superior atmospheric corrosion resistance. The target material is a soft-magnetic FeCo based target material made of an FeCo based alloy. The FeCo based alloy comprises 0 to 30 at. % of one or more metal elements selected from the group consisting of B, Nb, Zr, Ta, Hf, Ti and V; and the balance being Fe and Co with unavoidable impurities. The Fe:Co atomic ratio ranges from 10:90 to 70:30. The FeCo based alloy may further comprise 0.2 at. % to 5.0 at. % of Al and/or Cr.
摘要:
The benzylamine derivative represented by the formula below and a pharmaceutically acceptable acid addition salt thereof, and a pharmaceutical containing the derivative or the pharmaceutically acceptable acid addition salt thereof, and a therapeutic or prophylactic agent for pollakiuria or urinary incontinence containing the derivative or the pharmaceutically acceptable acid addition salt thereof are provided. The benzylamine derivative of the present invention and the pharmaceutically acceptable acid addition salt thereof have less possibility of occurrence of side effects than known compounds, and show a better therapeutic effect against pollakiuria or urinary incontinence, so that they can be used as excellent therapeutic or prophylactic agents for pollakiuria or urinary incontinence.
摘要:
A remote control toy system includes a plurality of sets each including a transmitter and a movable machine controlled on the basis of a control signal transmitted from the transmitter. An attack signal is transmitted from the movable machine on the basis of an attack order contained in the control signal and transmitted from the transmitter in response to an attack operation of a user. Damages due to an attack are processed and executed on a movable machine that has received the attack signal. Each of the movable machines includes a device for storing own offensive power information, a device for generating the attack signal that contains the offensive power information, a device for transmitting the attack signal, and a device for executing processing to make a degree of damage different, according to the offensive power discriminated from the received attack signal.
