The output signal 104 of the NAND circuit 5 is inputted to a driving circuit as an input signal. Thus, even if the signal 101 continuously becomes '0' level, the signal 102 is returned to a reset state ('0' level) after a predetermined period (Tw) of time is elapsed. Therefore, the transistor of the driving circuit is prevented.

Title: Automatic brightness compensation circuit of cathode-ray tube radar display unit
Inventor: NAGASHIMA HIROSHI
IPC: G01S7/06
Filed: 1979-11-28
Abstract: PURPOSE:To ensure an automatic control for the brightness of a CRT in correspondence to the change of the rotational speed of an antenna, by installing a frequency-voltage converter F/V and others and thus securing an automatic variation for the brightness of the CRT in correspondence to the rotational speed of the antenna. CONSTITUTION:The angle signal of the antenna 10 emerges as the output of the digital angle signal generator 11. The minimum angle signal of the digital signal is supplied to the F/V converter 12 to obtain the analog voltage which is based on the input/output properties. In other words, the analog voltage of the output increases as the rotational speed of the antenna increases. Accordingly, the compensated voltage amplitude V3' is obtained by supplying the analog voltage to the brightness control circuit 3. The amplitude V3' increases and decreases by the voltage value of the analog voltage V4, i.e., the rotational speed of the antenna. Thus the potential difference between the grid G and the cathode K of the CRT1 varies automatically by the rotational speed. In such constitution, the brightness is controlled automatically for the bright line on the CRT.

Filed: 1978-12-18
Abstract: PURPOSE: To decrease internal stress, to prevent deterioration in the initial stage and to lengthen life, by forming pn-junction on a neutral surface where stress between a semiconductor substrate and a crystal layer is zero.  
     CONSTITUTION: A heterogeneous material semiconductor device is made up by growing a crystal layer 2 on a semiconductor substrate 1. The warps of the semiconductor device depend upon the coefficients of thermal expansion of the substrate 1 and the crystal layer 2 and a method that the misfit dislocation of the interface is built up, and the internal stress of the crystal layer 2 is as shown in the figure. When a pn-junction surface is formed on a neutral surface 22, on which the internal stress δ=0, stress near to the junction is little, and life is lengthened. A material with heterogeneous structure need not be the specified material, and deterioration in the initial stage can be prevented by making up the junction on the neutral surface.
