Title: Characteristic correcting device
Inventor: TSUNASHIMA KENJI
IPC: H03M1/18
Filed: 1989-11-13
Abstract: PURPOSE:To easily and accurately execute level correcting operation by adjusting the level of a reproduced video signal by a level difference detecting means and a variable gain amplifier means and holding the reproduced video signal in a range appropriate for level correction. CONSTITUTION:At the time of reproducing a video signal, the level difference detecting means detects a level difference between a reproduced video signal and an original video signal based upon a reproduced reference level signal and outputs a level difference detecting signal. The variable gain amplifier means 16 adjusts the level of the reproduced video signal to the optimum level in response to the level difference detecting signal. The level-adjusted video signal is inputted to a level correcting means 13, which detects a signal correcting reference signal inserted into the blanking period of the reproduced video signal and corrects the level of the reproduced video signal based upon the height of the reproduced reference pulse and pulse height data. Consequently, level correcting operation can be effectively executed even by a signal recording/ reproducing device having no time base collector device and the level adjustment of a reproduced signal can be omitted.

Abstract: PURPOSE:To enable always displaying of a correct fuel residue by displaying a detection value (fuel residue) when a rate of change per unit time of the detection value of a residue detection means for detecting the fuel residue in a fuel tank of a vehicle is a normal value. CONSTITUTION:A residue detecting section 1 outputs a voltage corresponding to a level of a liquid surface of a fuel in a fuel tank as detection data G and the data G is inputted into a reasoning part 3 and a differentiation part 2. The differentiation part 2 performs a differentiation computation of the data G and the results are outputted to the reasoning part 3 as rate of change of DELTAG per unit time. The reasoning part 3 judges whether the data DELTAG is above a reference rate of change or not. When the rate of change in the data DELTAG is abnormal, no detection data G is outputted from the reasoning part 3. When the data G as abnormal value is inputted continuously at a specified frequency, the data G(t) inputted currently as display data S1 is outputted to be displayed 4 while an abnormal data S2 is outputted. In other words, for example, a trouble of fuel leakage is determined to occur to perform an abnormal display indicating the generation of the trouble on an abnormality display device 5.

For example, a usual shifting gate pulse voltage is 10V, and -5V is used as -VSS, and then, the voltage impressed equivalently to the shifting gate 3 comes to be 15V and an approximately complete depletion can be executed.
