Filed: 1991-03-19
Abstract: PURPOSE:To attain the suitable color discrimination by considering the hue and saturation of a substance which becomes an object and is travelling or is remote and discriminating the tint of the screen coalesce. CONSTITUTION:A color image held at an image holding circuit 13 is sent to an RGB/HSI converting circuit 14 and converted to respective images H, S and I. At an H image slice circuit 15, the hue near 85 counting is removed, inputted to a mask preparing circuit 16 and a mask image is generated. An S image obtained by the RGB/HSI converting circuit 14 is inputted through the image holding circuit 13 to a multiplying circuit 17, and multiplied and overlapped with the mask image from the mask preparing circuit 16. At a standardizing circuit 18, the mean value of the saturation of the color area which becomes an object out of the color images and the area ratio which rate the area occupies in the image is are calculated, both are multiplied and the standard value to show the tint of the whole screen is obtained. The standard value is inputted to a deciding circuit 19 and the threshold and the standard value are compared and decided.

Abstract: PROBLEM TO BE SOLVED: To prevent the deviation in position of an Si chip by making a peripheral part of a semiconductor mounting section of a metal plate thicker than the other part, in a junction substrate made by joining metal plates to a ceramic substrate. SOLUTION: To both faces of a ceramic substrate 1, copper plates of, for example, 0.4mm and 0.4mm are directly bonded as a circuit board 2 and a radiation plate 3 respectively at a given temperature in an inactive atmosphere. After that, etching resist is applied onto the circuit board 2 and then a pattern is printed and then the resist is hardened and an etching is conducted to form a copper pattern. Nextly, the circuit plate 2 except for a chip mounting section 4 is half-etched to make it into, for example, 0.25mm in thickness and then the circuit board 2 is so half-etched that a peripheral part of the chip mounting section 4 may be thicker than the other part to obtain a chip mounting section of, for example, 0.30mm thickness. After that, a solder plate of, for example, 0.10mm thickness in the same size as that of an Si chip is mounted on the chip mounting section and then an Si chip is mounted on the solder plate and heating is conducted in a reduced atmosphere to solder the chip.

Abstract: Molded bodies of SiC ceramic can be firmly bonded to each other or to molded bodies of other ceramic material or to metal workpieces by the establishment of diffusion-welding conditions when a metal alloy layer is interposed between cleaned and polished surfaces that are to be joined. The alloy metal of the layer is MnCu or MnCo or multi-component alloys containing the foregoing as a base and additions of other metals to a total percentage not exceeding 70% with each single other metal being present in the range from 2 to 45% by weight. Such other metals constitute 1 or more of Cr, Ti, Zr, Fe, Ni, V and Ta. The Mn, Cu alloy or alloy base has a Cu content from 10 to 90%, preferably 25 to 82% and the MnCo alloy or alloy base has a cobalt content of 5 to 50% by weight. MnCuFe eutectic compositions containing 5 to 30% by weight Fe and 10 to 90% by weight Cu and MnCoCr eutectic compositions with chromium content from 2 to 45% by weight are preferred, especially 50:40:10 MnCuFe and 60:30:10 MnCoCr. Preferred alloy metal layer thickness is from 5 to 200  mu m, especially about 10 to 50  mu m. In the case of SiSiC bodies, a preliminary treatment to convert free silicon at or near the surface to be joined into silicon nitride or silicon carbide is desirable. The provision of the alloy metal layer between the surfaces to be joined may be performed by interposing an alloy metal foil between the surfaces or by sputtering or vapor-deposition of the alloy on a silicon carbide surface to be joined. The diffusion welding is performed at a temperature lower than the melting point of the alloy layer by 20 DEG  to 300 DEG  C. while the surfaces to be joined are pressed together with a force of from 0.5 to 60 MPa.

Abstract: PURPOSE: To electrically detect the liquid level or the remaining liquid amount from the apparent weight of weights, by avoiding the moving part of the liquid level meter through the system suspending weights in place of float.  
     CONSTITUTION: The weight SP having greater specific gravity than the liquid L in the liquid tank 1 is fixed to the suspension frame SP' as shown in figure. The weight of the weight SP is delivered to the reception plate 4 via the adjusting bolt 3 screwed to the suspension frame SP', the piezo-electric element 6 detects the weight and converts it into electric amount corresponded. Further, the reception plate 4 is mounted on the piezo-electric element 6 and it is not fixed on the housing 2 and it receives the weight of SP. The weight SP receives buoyant force proportional to the length in the liquid L, that is, the height of the liquid surface L', and the electric quantity from the piezo-electric element 6 is changed accordingly. Based on the change in the electric quantity, the liquid level is measured. Since the weight SP is not fluctuated like float, friction and wear are not caused.
