Title: Radio-wave radar equipment
Inventor: HATASHITA HIROSHI
IPC: G01S13/28
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a radio-wave radar equipment for measuring the distance to a target by suppressing the occurrence of a shadow distance and avoiding the occurrence of interference with other radio-wave utilization. SOLUTION: The wavelength is set shorter than the irregularity size of a target 500 for the carrier wave of the radio wave emitted from a transmitting antenna 140. Then, the modulation of a spread spectrum method is performed. The received signal, which is reflected from the target 500 and received by a receiving antenna 210, is demodulated with the same local reference signal as the carrier wave. The correlation between the demodulated signal and the spread spectrum signal is obtained. The distance to the target 500 is measured based on the time delay, which makes the autocorrelation function maximum. An alarm is generated by an output part 300 in correspondence with this distance.

Abstract: PURPOSE: To ensure the compensation to keep the constant output voltage, by applying the compensation voltage set previously and corresponding to the reduction of the output voltage to the control loop when the power units being driven in parallel are cut off from each other.  
     CONSTITUTION: Power units 9 and 12 are driven in parallel until time t 0  of the normal state, and thus output voltage V 0  is supplied to the load. Relay 14 is under the nonworking state with b-contact X 2 b closed each. Accordingly, rectilinear signal 11a is applied to capacitor C1 to keep the terminal voltage at constant voltage V 21 . If some fault occurs to unit 12 at time t 0 , fault detection circuit 8 actuates relay 14 at time t 1 . Thus contact X 2 b is opened at unit 9 with a-contact X 2 a closed each, and accordingly the voltage of C1 is applied to adder 15 as shown in fig. (a). This voltage, i.e. compensation voltage signal V 2  is applied to the control loop including inverting circuit 3 and control circuit 4 each via adder 15. As a result, voltage V 0  can hold the constant level as shown in fig. (b).

Abstract: PURPOSE:To increase the document input processing speed, by adding an A area of a prescribed capacity for each page of (n characters)X(m lines) of a memory, storing the excessive input information over the (n characters)X(m lines) of document information to the A area and providing a sequential operating means to the next page. CONSTITUTION:In forming a document, when a format of (n characters)X(m lines)X(P pages) is set, a format set section 202 of a CPU adds an Ai (where i=1-P) with a prescribed capacity at each page and each unit of (n characters)X(m lines), and a memory area securing the P page's share is set as a document memory 201. After the document information is inputted to a page area Pi, the information overflowed over (n characters)X(m lines) is stored in the area Ai with edition and proof reading. In calling a certain page, when a page arrangement instruction key 204 is operated, a page arrangement section 203 sequentially transfers the information inserted in the area Ai to the head of a page area Pi+1 on the next page. If the page Pi+1 exceeds (n characters)X(m lines), sequential transfer to the page Pi+2 is generated. Thus, the number of execution times of the sequential transfer can be reduced and the document input processing speed can be increased.

Abstract: PROBLEM TO BE SOLVED: To reduce a time till the frequency and phase of an input signal and of a VCO output signal respectively match each other in a locked state by providing a frequency matching means and a phase matching means to the PLL circuit. SOLUTION: Since a frequency change in a loop filter 30 being a component of a PLL circuit 10a is equivalent to the change in a voltage across a capacitor C1, the operation requires some time attended with charging/discharging operation of the capacitor C1, but since a phase change is equivalent to the change in a voltage across a resistor R2, the change is attained quickly. In this circuit 10a, till the frequencies are matched, charging or discharging of the loop filter 30 is conducted, and after the frequencies are matched, the phase is being matched while repeating charging/discharging, then in the case of frequency matching, the frequency approaches a prescribed frequency from a lower frequency or a higher frequency and charging/discharging is not repeated.
