Title: Joint structure and connection method of deformed bar
Inventor: SAKUMA YOSHIKAZU
IPC: E04C5/18
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a joint structure for deformed bars, which is strong and excellent in workability. SOLUTION: A steel pipe provided with recesses at the periphery thereof is used as a joint sleeve of a so-called mortar injection joint. One end of the sleeve 2 is fixed in advance to the front end of one of deformed bars 1 and this is used as a vertical bar and the opening of the sleeve 2 is turned upward and fixed. The other deformed bar is inserted in the opening and both bars are arranged to butt each other in the sleeve. Then, a grouting material is poured from the opening to fill the space S formed between the inner periphery of the sleeve and the bars. Then the opening is bound with pressure by a pressing device to confine the grouting material and cure it. In this way, the sleeve 2 and the reinforcing bar are firmly connected by the mortar. And since it is strong and light, the workability becomes excellent.

Filed: 1992-12-22
Abstract: PURPOSE:To improve the quality of an image signal without improving the conversion accuracy of an A/D converter by correcting conversion error characteristics with the output of the A/D converter. CONSTITUTION:Image signals from a CCD are converted to continuous signals by an S/H circuit, inputted to an A/D converter 3, turned to digital signals and supplied to an A/D error correction circuit 4 later. At such a time, an A/D conversion error signal is stored in a memory 105 of the correction circuit 4. Then, the conversion error signal stored in the memory 105 is added to the output signals of high-order and low-order comparators 101 and 104 at the A/D converter 3 by an adder 106, corrected and processed by a video signal forming means. Thus, high-quality image signals can be provided by correcting the conversion error of the A/D converter with simple circuit configuration.

IPC: H04N5/355
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To solve a problem of a conventional solid-state image sensing device that has had a narrow dynamic range because an output of the conventional solid-state image sensing device provided with a vertical overflow drain is increased as the luminous quantity increases even when excess charges are swept out to the overflow drain, it is required to set a higher voltage to a substrate in order to prevent charges equal to or over the maximum transfer charges from entering a charge transfer register thereby decreasing the maximum electric charge quantity in a linear region (a region where storage electric charges are proportional to an incident luminous quantity). SOLUTION: A part of the stored electric charges in a photoelectric conversion region is swept out to the substrate by applying a sweep-out pulse to the substrate just before reading the storage charges in the photoelectric conversion region through the application of a read pulse so as to prevent electric charges equal to or over the maximum transfer charge quantity from entering the charge transfer register.
