Title: Leak detecting method for low temperature liquid
Inventor: NUKUI KAZUMITSU
IPC: G01M3/02
Filed: 1986-01-13
Abstract: PURPOSE:To monitor a wide space at low cost and to securely detect a leak of low temperature liquid by detecting variations of a visible light image and a temperature image in the monitor area by a visible-light image detector and an infrared-ray image detector. CONSTITUTION:If the low temperature liquid leaks from piping 1, etc., the temperature near the leak place 6 falls and moisture in the atmosphere is condensed to produce white smoke 7. Temperature variation is detected by the infrared-ray image detector 4 and visual image variation of the white smoke, etc., is detected by the visible-light image detector 4 respectively and they are monitored by a monitor device 5. A line image is varied by any other cause than the leak of the low temperature liquid, but when both images vary at the same time, it is considered that is caused by the leak of the low temperature liquid. Thus, the wide space is monitored at low cost and the leak is detected securely.

Title: Half-tone reproduction system for facsimile or the like
Inventor: OOHIRA HIDEAKI
IPC: H04N1/407
Filed: 1979-01-19
Abstract: PURPOSE: To reproduce an excellent half tone without reference to the kind of a recording system by linearly varying recording density indicating each gradation to or from a threshold level.  
     CONSTITUTION: Counter 23 is cleared at the rise of a reset signal and put into counting operation by a reference signal. Its count content is supplied to decoder 22 and memory circuit 24 as a count signal showing terms of 2 0 ∼2 3 . Decoder 22 selects an output terminal that the count signal assigns and then feeds power. Since resistances R 2 ∼R 9  have their values set depending upon recording density characteristics here, a desired threshold voltage level can be set. Then, the threshold voltage level varying sequentially from a higher voltage synchronizing with a reference clock signal is compared by comparator 21 with an input analog picture signal and only when the picture signal is higher, an output signal is held high in level to stop counter 23 from operating. Circuit 24 stores the count signal at the rise of a set cycle signal of the threshold level to output a level signal. In addition, counter 23 stopping to operate is all cleared at the rise of the reset signal. Then, this operation is performed repeatedly.

Filed: 1988-01-12
Abstract: PURPOSE:To attain the use of a smoothing circuit with a short time constant and to output a pulse width with fidelity to the duration time of an inputted pulse modulation wave by applying full wave rectification to an inputted pulse modulation wave and applying level comparison immediately. CONSTITUTION:A pulse modulation wave A inputted between terminals 101 and 102 is rectified by a full wave rectifier circuit 107 comprising diodes 103-106 to obtain a waveform B. The output is fed to a level comparison circuit 108, compared with a reference voltage V, a level larger than the reference voltage V to obtain a waveform C. The waveform is fed to a smooth circuit 110 comprising a resistor 109 whose resistance is R' (OMEGA) and a capacitor 110 whose capacitance is C(F). The output waveform D is fed to the next stage processing circuit or the like from terminals 112, 113. Then the waveform C shows positive polarity mostly during the duration time of the pulse modulation number and represents '0' at the changes when the input waveform changes from the positive to the negative polarity. Since the smoothing circuit 111 has only to have a time constant holding the positive level for a very short time descending to '0', the pulse width with fidelity to the duration time of the inputted pulse modulation number is outputted.
