Title: Tracing device for travelling object
Inventor: YAMADA MATSUICHI
IPC: H01Q3/00
Filed: 1981-01-27
Abstract: PURPOSE:To simplify the constitution and to increase the reliability, by converting a tracing angle error signal into an on/off signal at a comparator and controlling a motor. CONSTITUTION:When a motor 6 is rotated clockwise, an antenna 1 is driven so that an angular error voltage is reduced toward negative value, and when the motor is rotated counterclockwise, the antenna 1 is driven so that the voltage is increased toward positive direction. When an output of a comparator 8 is a positive on signal, the motor 6 is driven by an on/off switching device turning on the power supply so that the motor 6 is rotated clockwise, and when the output of the comparator 8 is a negative on signal, the power supply turns on so that the motor 6 is rotated counterclockwise. While the comparator 8 outputs an off signal, the power supply is interrupted. When the power supply of the motor 6 turns on/off with the decision of the comparator 8, the antenna 1 is driven so that an angular error between a flying object and the antenna 1 is eliminated to trace the flying object. The accuracy of tracing can be arbitrarily varied with reference voltages V1--V4 of the comparator 8.

Inventor: SAKO YOICHIRO
IPC: H03M13/00
Filed: 1986-01-21
Abstract: PURPOSE:To effectively correct a burst error by performing the correcting processes successively for series of 2-dimensional arrays so as to attain the alternating processes and correcting the series at the other side again after correction of the series at one side in case the correction is impossible for the series at the other side. CONSTITUTION:An address generating circuit 2 produces the address data to read the data on the column and row blocks alternately out of a memory 1 through the column or row block with which the decoding is started. A control circuit 6 produces the control signal to correct again the blocks preceding the block at the other side in case the correction of errors is impossible for the block at the other side after correction of errors of the block at one side when the column and row blocks are corrected alternately. The control signal of the circuit 6 is supplied to the circuit 2. Thus such errors that could not be corrected by a conventional method may sometimes be corrected by this new method. In such a way, correcting capability for burst errors is improved.

Abstract: PROBLEM TO BE SOLVED: To obtain a new crystal element which can generate short wavelength light and contains boron trioxide as the basic structure by using an element for generation of short wavelength light comprising a specified crystal. SOLUTION: A yttrium-calcium-oxyborate crystal wavelength converting element is produced by using an element for generation of short wavelength light comprising a yttrium-calcium oxyborate crystal expressed by YCa4 O(BO3 )3 . The birefringence of the obtd. crystal is 0.041 at 1064nm wavelength and 0.0433 at 532nm wavelength, which is larger than a GdCOB crystal having 0.034 birefringence. The limit wavelength for generation of second harmonic waves resulted from the birefringence is 720nm, which is short by about 120nm. Since the obtd. nonlinear optical crystal YCOB element can be grown from a molten state, a large crystal can be grown in a short time and the obtd. crystal is excellent in mechanical and chemical characteristics. The obtd. YCOB crystal element is useful as a nonlinear optical crystal to generate UV rays.
