Title: Supply source turn-off type water boiler
Inventor: NISHIKAWA MAKOTO
IPC: F24H1/20
Filed: 1980-03-31
Abstract: PURPOSE: To improve handleability and safety of the titled device by a method wherein a tubular body having a resisting plate coupled to a float is arranged is connected between a water supply pipe and a hot-water tank.  
     CONSTITUTION: On the secondary side of a valve 12 for controlling the quantity of supplied water, which is provided at the water supply pipe 1 is connected the tubular body 3 wherein the resisting plate 4 coupled to the float 6 and moved by the pressure of supplied water is arranged. An opening at the end part on the water-inlet side of the tubular body 3 is made small, while the space at the rear end part thereof is made large, and the resisting plate 4 is fitted freely in the body. The float 6, made of a hollow synthetic resin body, is made to appear above or disappear below the level of water, whereby the change in the level of water is made large. When the valve 12 is opened, the water flowing into the tubular body 3 presses the resisting plate 4 down to the rear end part, pressing down also the float 6 through an extension shaft 5 and making the same sink below the level of water. Then the level of water inside the hot-water tank 2 rises sharply and the hot water is discharged from an overflowing port 8, and when the valve 12 is closed, the pressure of the supplied water on the resisting plate 4 is removed, the float 6 comes up on the level of water with buoyancy and thereby the level of water inside the hot-water tank 2 is lowered sharply.

Abstract: PROBLEM TO BE SOLVED: To provide a misfire detecting device capable of measuring and discriminating abnormal combustion and an amount of a misfire at a low-cost with high-precision by diverting a rotation speed detecting sensor used in an electronic control engine and a generating power signal. SOLUTION: The rotation angular velocity of the output shaft of an internal combustion engine is measured and an angular velocity fluctuation amount Fn being a difference between an average rotation angular velocity and a measuring rotation angular velocity is obtained. Based on an angular velocity fluctuation amount reference Fs predetermined corresponding to the rotation angle of an output shaft at each measuring point of time and the angular velocity fluctuation amount Fn, an angular velocity fluctuation difference G is determined and an angular velocity fluctuation amount Da in a given stroke is led out.  To discriminate the misfire state of an internal combustion engine based on the angular velocity fluctuation difference amount Da, a misfire is discriminated by the angular velocity fluctuation difference amount Da representing an abnormal rotation fluctuation except a rotation fluctuation due to a fluctuation of an engine load. According to the misfire discrimination reference, the angular velocity fluctuation amount reference Fs is updated in correspondence to an angular velocity fluctuation difference amount Da.

Title: Extracting method of framework line of linear pattern
Inventor: SAKAI TOSHIYUKI
IPC: G06V30/168
Filed: 1982-03-18
Abstract: PURPOSE:To extract the framework line of a linear pattern, by extracting coccyx points, i.e., the information on 2-dimensional variable density of the linear pattern and connecting the spine points. CONSTITUTION:When the framework line of a linear pattern like a character, a chart, a graph, etc. is extracted, the linear pattern is observed through an observing window. Then the center picture element E in the observing window is extracted as a coccyx point when the density value of the element E becomes maximum in >=2 directions. In other words, the density of the picture element within the observing window is compared among 4 directions D1, D2, D4 and D8, and the direction where the element E becomes maximum. Such decision is done for all picture elements of the linear pattern while shifting the observing window for each picture element. Thus the coccyx points are extracted. Then a label showing the directivity of the coccyx is attached to the coccyx point. A direction (dotted line is direction where the center value is not maximum) where the  density value of the coccyx point is not maximum at its center is allotted to the label. Then the picture elements extracted as spine points are connected to each other in consideration of the above-mentioned direction of the density value. Thus the framework line of a linear pattern is extracted.
