Title: Agc smoothing circuit
Inventor: KITAYAMA HIROTOSHI
IPC: H03G3/30
Filed: 1987-07-22
Abstract: PURPOSE:To obtain a smoothing circuit where a charging time for a DC detection voltage reaching 2VBE or over from 2BE or below is independent of the discharge time of 2VBE or below by clamping a DC detection voltage terminal to GND when the DC detection voltage reaches 2VBE or below. CONSTITUTION:An AC voltage given to an AC detection voltage terminal is smoothed into a DC voltage and the voltage from a DC detection voltage terminal limits the current at a current control terminal. When the voltage at the DC detection voltage terminal is 2VBE or over, the discharge time is decided by a base current of an NPN transistor(TR) 5 and a capacitor 21. On the other hand, when the terminal voltage at the DC detection voltage is 2VBE or below, the current from the current mirror circuit flows to the base of an NPN TR 7 by a differential amplifier comprising NPN TRs 4, 5 to clamp the DC detection voltage terminal near the GND potential. Then the smoothing circuit having the discharge time where the DC detection voltage is independent of the length of the discharge time with the DC detection voltage of 2VBE or below.

Abstract: PURPOSE:To eliminate punch-through and improve the quality and performance of an MOS IC by a method wherein, after a gate electrode is formed on a one conductivity type semiconductor substrate with a gate insulating film between, impurity ions are implanted into a channel region and source and drain regions. CONSTITUTION:Phosphorus ions are implanted into a channel region and regions for forming source and drain with a high concentration over a gate electrode 13 to form an n<+>type region 63. If an acceleration voltage of as high as several hundreds of voltes are applied,at the time of the ion implantation, ions can be transmitted through the gate electrode 13 and the n<+>type region is formed under an n<->type region 61. On the other hand, the parts of the n<+>type region 63 under the regions for source and drain are formed far below the n<->type region 61. The dosage of phosphorus ions is as high as about 10<12-13>/cm<3>. As the high concentration n<+>type region 63 is formed in the channel region between a source region 5 and a drain region 5, the spread of a depletion layer is suppressed and punch-through can be eliminated. Moreover, the n<+>type region 63 is formed apart from the bottoms of the source and drain regions 5, the dielectric strength is not deteriorated and a parasitic capacitance can be reduced.

Abstract: PROBLEM TO BE SOLVED: To correctly show the true course of a target, even if a vector time of the tracking target is made zero value and even if relative vector display is performed, by showing a symbol in response to the target true course. SOLUTION: Radar echoes 12a-15a and symbols 12c-15c showing a true course are shown on a scope 21 for changing vector display for relative vector display.

Abstract: PURPOSE:To secure the switch output by obtaining the switch output with one optical sensor and the diagonistic output with the other optical sensor, and changing the diagonistic output to the switch output when one of the optical sensors gets out of order. CONSTITUTION:In the process that an actuating piece 15 moves from the free position to the operating position, the light from projecting elements 25 of an optical sensor 23a reaches light receiving elements 26 through a transmission window 27, and the operating output is output from the sensor 23a.
