Title: Displacement measuring device
Inventor: SHIBATA KAZUTO
IPC: G01D5/245
Filed: 1993-11-18
Abstract: PURPOSE:To properly inform the generation of abnormality even with respect to gradually advancing abnormality by providing a cumulated tolerance difference memory means storing the value of a measuring error and detecting abnormality from the change tendency of the measuring error. CONSTITUTION:In a displacement measuring device using an encoder A1 to measure the displacement of an object to be measured, a measuring error detection means A2 detects the measuring error at a reference position. When the measuring error detected by the detection means A2 is a predetermined value or less, a cumulated tolerance difference memory means A3 stores the value of the measuring error. A device abnormality judging means A4 judges the generation of device abnormality from the change tendency of the measuring error stored in the memory means A3. Since the measuring error detected at every measurement by the detection means A2 is stored in the memory means A3, the generation tendency of the measuring error can be detected. Therefore, gradually advancing abnormality can be detected and the judging means A4 can inform the generation of abnormality in a relatively slight trouble stage.

Abstract: PURPOSE: To perform compression encoding of data in an image with high efficiency by encoding the residual component of a predictive image and an input image in a current frame corresponding to reliability functions on the candidate positions of eyes or mouth in the image. CONSTITUTION: A synthesizer 3 forms a predictive image 24 of the current frame by deforming a preceding frame image 21 corresponding to the reliability functions of candidate positions based on motion parameters provided from a motion analyzer 2. A threshold value processor 8 inputs a residual component 25 of the predictive image 24 and an image 22 of the current frame and inputs a reliability function 26 provided from a searching device 1. When the reliability functions are '1' and '0' concerning an image area x-y, a threshold value is turned to '0' and adjusted the more the reliability functions get close to '0' and '0', the more the threshold value can be enlarged. Then, threshold value processing 27 is performed to the residual component 25 and the function 26, and they are outputted. In this case, an encoder 4 transmits the residual component 27, to which threshold value processing is performed, and the motion parameter outputted from the motion analyzer 2 to the side of a receiver. Thus, the data in the image are compressed and encoded with high efficiency.

Abstract: PURPOSE:To provide a safe constitution of a heat exchanging device in which a home-use hot water feeding or heating equipment can be used for a long period of time. CONSTITUTION:Fins 13 and a fin pipe 14 are connected by a connector pipe 15 outside a drum 11. A clearance size L at a part (a) at an end part of a heat exchanging chamber of the fins 13 is set wider than another clearance size S, and an excessive temperature increasing prevention device 16 is fixed to the connector pipe 15 at the part (a). Some scale adheres to the clearances of the fins 13 to clog the clearances. However, the clearance size L at the part (a) is set to be wider than the other clearance size S, so that even if the scale adheres to it, the clearance is hardly clogged and a large amount of combustion gas flow at the clearance at the part (a) and the combustion discharging gas flowing between other fins 13 shows a small amount of flow. Due to this fact, a temperature of the fin pipe 14 to which the temperature over-heating or increasing prevention device 16 is fixed is increased more than a normal temperature at an output and then the temperature over-heating preventing device 16 may operate.
