Title: Synchronizing signal processing circuit for monitor
Inventor: KIN EIMIN
IPC: H04N5/06
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent a cathode ray tube from being damaged by constituting so that the surface of the cathode ray tube on which a video signal is scanned is moved when a key is not inputted for a fixed time. SOLUTION: A shaping part 110 shapes a synchronizing signal to output a shaping signal, and the shaping signal is supplied to a first inversion part 120, and the first inversion part 120 inverts the shaping signal to output a first inversion signal. At this time, the shaping signal is supplied to a second inversion part 140, and the second inversion part 140 inverts the delayed shaping signal to output a second inversion signal. When the second inversion signal is outputted, the output of the first inversion signal is stopped according to a switching state of a control part 130, and the second inversion signal is supplied to a synchronizing signal output part 150, and the synchronizing signal output part 150 inverts again the second inversion signal.  That is, the first inversion signal and the second inversion signal are outputted repeatedly according to the switching state of the control part 130, and the video signal is synchronized with the first inversion signal or the second inversion signal and scanned on the cathode ray tube.

Title: Abnormality judgment method of water-level detector
Inventor: MORIO SHUJI
IPC: G01F25/00
Filed: 1994-09-28
Abstract: PURPOSE: To obtain an abnormality judgment method in which an abnormality can be confirmed easily and at low costs by a method wherein, when the ON-state and the OFF-state of the detection signal of an electrode rod are changed and their change direction and the detection signal of an adjacent electrode rod on the opposite side are not established logically, the electrode rod or the adjacent electrode rod is judged to be a failure. CONSTITUTION: Respective electrode rods 1 to (n)... are connected to a power supply. When a water level WS comes into contact with their lower ends, the electrode rods are set to continuity, and a signal flows so as to become an ON-state. When the water level is separated, the signal is set to an OFF-state. The ON-state and the OFF-state are output to a microcomputer, and an abnormality is judged. Then, when a water-level detection state is changed, only two electrode rods, i.e., the electrode rod and the adjacent electrode rod, are grasped, and the ON-state or the OFF-state is judged. When the read-out signal is a signal which cannot be established logically, the existence of the abnormality can be judged, and its judgment program is simple. Consequently, the creation cost of the program and the cost of a ROM can be reduced.  The abnormality is judged between the two adjacent electrode rods. Even when the electrode rods are increased or decreased, the existence of the abnormality can be judged by using the same judgment program.
