IPC: H04B1/7095
Filed: 1988-11-14
Abstract: PURPOSE:To speed up synchronization between a received signal and a reference code by providing a code generating means to generate the reference code, a convolving means to take correlation between the received signal and the reference code, a peak detecting means and a code synchronizing means. CONSTITUTION:The convolver 11 takes the correlation between a received diffused signal and the reference code generated by a generator 17, and the peak detection circuit 13 detects the peak of the output of the convolver 11, and outputs it. Next, a phase comparator 14 controls a voltage controlled oscillator 16 so that a clock which is generated by a frequency divider 18 and synchronizes with the reference code coincides with the clock which is generated by the circuit 13 and synchronizes with the received diffused signal. Besides, a diffused code generator 17 outputs a reference diffused code system starting point signal to a variable delay circuit 111 so as to synchronize with time when one period of the reference diffused code coincides with the integration area of the convolver 11. The circuit 111 operates so as to delay an input signal by twice longer time then the time from the input of the signal till the rise-up of the output of the frequency divider 18. Thus, synchronism acquisition is attained, and the synchronization between the received signal and the reference code can be made fast.

Title: Raster width adjusting device
Inventor: URUFUGIYANGU FURIIDORIHI UIRUH
IPC: G09G1/16
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To attain display with high quality by obtaining an increased deflection current requiring to compensate a reduced raster width caused by a increased alter voltage which might sometimes decrease the raster width in a short time. SOLUTION: On the occurrence of a short-time increase in an alter voltage which might sometimes cause reduction in the raster width, the reduction in the raster width is given to an inverting terminal of an amplifier U1. As a result, the conduction amount of a serial current path transistor(TR) Q10 is increased thereby increasing a deflection voltage. Thus, the increased deflection current requiring to compensate the reduced raster width caused by the increase in the alter voltage is obtained. When the alter voltage that might sometimes causes the decreased raster width increases, a line deflection voltage adjustment device 60 of a line receiving the feedback voltage acts like increasing its output thereby increasing the deflection current resulting that the raster width is increased. As a result, the reduction in the raster width caused by the alter voltage is compensated.

Filed: 1990-10-26
Abstract: PURPOSE:To use a unit antenna with a long boom length and to attain quick tracking by forming a support arm with plural rotary arms and connecting plural directional antennas to the plural arms turnably respectively. CONSTITUTION:Plural arms 12a, 12b being components of a support arm 12 are turned by a same angle respectively around plural rotary shafts 14a, 14b placed on a line. Thus, when the rotary shafts 14a, 14b are turned, the plural arms 12a, 12b are turned by a same angle to keep the parallel state. Moreover, plural directional antennas 11a-11d are connected to plural positions around the center of a boom in a way of being turned with respect to the plural arms 12a, 12b. Thus, when the rotary shafts 14a, 14b are turned, the boom of the directional antennas 11a-11d and the plural arms 12a, 12b trace a satellite while they form a parallelogram. Thus, the antenna with a long boom and high directivity gain is usable as a unit antenna 11 and the antenna is turned quickly with a small power.
