Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To prevent a burner inspection hole from being choked without necessitating piping of an air supply pipe and without lowering thermal efficiency, by a method wherein secondary air in a wind box is introduced into an inspection hole main body as the air for sealing the burner inspection hole. SOLUTION: A burner inspection hole 26 is so constructed that part of secondary air 4 in a wind box 3 having a prescribed positive pressure flows into an inspection hole main body 28, as air 25 for sealing, from a sealing air intake port 27 provided for the inspection hole main body 28 and flows out from the end of the inspection hole main body 28 opening inside a throat 2 in a state of negative pressure. As the result, the part of the opening of the inspection hole main body 28 is sealed with the air 25 for sealing flowing through the inspection hole main body 28 and ashes produced by combustion is prevented from penetrating into the burner inspection hole 26. According to this constitution, an air supply pipe for sealing is dispensed with and, moreover, by using the preheated secondary air, choking of the burner inspection hole can be prevented without lowering thermal efficiency.

Abstract: PURPOSE:To improve the reproducibility of a video signal by converting an inputted analog luminance signal and an inputted color difference signal into the digital signals, outputting the correction data based on those digital signals, and correcting those analog luminance signal and color difference signal based on the analog correction signal obtained by converting the correction data. CONSTITUTION:The inputted analog luminance signal Y and color difference signals R-Y and B-Y are converted into the digital signals by the A/D converters 1A-1C. Based on the levels of these digital signals, the correction data is outputted from a correction data storage means 6. This outputted correction data is converted into the analog correction signals by the D/A converters 3A-3C, and the inputted signals Y, R-Y and B-Y are corrected by the correction signal. In this case, the means 6 is turned into a rewritable one and the contents of the means 6 are rewritten. Thus the signal correction is carried out in proper accordance with the characteristics of the inputted luminance and color difference signals. As a result, a video signal which excels in the color reproducibility is obtained.

Abstract: PURPOSE:To reduce the communication time and to save a recording medium by providing an edit means and a reduction means to reduce plural originals into a data quantity equivalent to one original before a compression section. CONSTITUTION:Reduction keys (1/2, 1/4...) in interlocking with a reduction rate setting section 21-2 is provided to the facsimile equipment, and a thinning section 21-1 thins bits in one line and between lines of an original picture read from a picture memory 15 with a prescribed thinning ratio of bits and lines in a range that the picture content is understandable. A resulting picture data is fed to an edit section 21-3, in which the arrangement to edit plural originals into a data quantity equivalent to one original is set by a page constitution key in linking with the edit section. For example, the picture is reduced to, e.g. 1/2, two originals are edited into one original in a way that the two originals are arranged to the left and right side of one original, a compression section 21-4 compresses codes and the result is stored in a picture code memory 15.

Title: Heating cooker
Inventor: ORITA MASATOMO
IPC: F24C3/06
Filed: 1982-07-26
Abstract: PURPOSE:To facilitate mounting of a control part and to prevent the occurrence of a clearance, by a method wherein, in a heating cooker that the positions and centers of a control part and a part to be controlled are displaced, a groove, formed in a control shaft for operationally coupling the two parts through a gear, is engaged with a cocoon-shaped hole on the body side. CONSTITUTION:A shaft 22' is inserted into a large-sized part D of a cocoon- shaped hole A formed in a control panel 24 to drop it in the direction of an arrow mark (a). This causes a recess part (c), provided in a shaft 22, to mate a small-sized part (d) of the cocoon-shaped hole A to bring it into a condition shown by a solid line. Since diameter (d) of the small-sized part of the cocoon- shaped hole A is smaller than diameter d2 of a part except the recess part (c) in the shaft 22, this constitution restrains movement in the direction of a horizontal axis of the shaft 22'. Thereafter, a mounting plate 25 is engaged with the shaft 22 to secure it to a control panel 24. This restrains vertical movement of the shaft 22 which is coupled to a part to be controlled, not in the drawing, shown, through a gear, not shown also. This constitution facilitates mounting of a gas cock shaft and positioning the gas cock.
