Title: Construction method of concrete structure
Inventor: SHINDO TAKEFUMI
IPC: E04B1/21
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To sharply reduce a reinforcement quantity in a joining part, and to construct an economical and high-quality structure by placing blending concrete having large compressive strength and bond strength in the joining part of a column and a beam. SOLUTION: Portland cement, a particulate body, an aggregate grain having the maximum grain size not more than, for example, 800 μm; nonferrous metal fiber having the length of, for example, 4 to 20 mm and the length of 10 to 20 times the aggregare grain, a high performance water reducing agent or a high performance AE water reducing agent are mixed by setting the water- cement ratio to a range of, for example, 10 to 30% In this high strength concrete, for example, compressive strength becomes 500 to 2000 kg/cm2, and bond strength becomes 300 to 800 kgf/cm3. Thus, since the bond strength can be expected when using this high strength concrete in a joining part of a column 2 and a beam 1, the length of a lap joint can be sharply reduced.  Since there is no need to arrange reinforcements for reinforcing shear, manhours of bar arrangement work of a joining part can be reduced, time can be shortened, and concrete placing work can be facilitated by a cut and a reduction in a steel material quantity of the joining part.

Title: Thermal head driving circuit
Inventor: ISHII HIROSHI
IPC: H04N1/23
Filed: 1985-06-11
Abstract: PURPOSE:To reduce a stray circuit current and to simultaneously drive all of electrodes without erroneous recording and to attain to enhance a recording speed, by driving the adjacent electrode corresponding to recording input at reversal potential and driving the adjacent electrode corresponding to non- recording input at the same potential. CONSTITUTION:Electrodes 3-1, 3-2, 3-3, ... 3-N are simultaneously driven by the outputs of AND gates 5-1, 5-2, ... 5N. When CLOCK input is 'H', recording data inputs D1, D2, ... D(N-1) become effective. However, before recording data input passes through an AND gate 5, by an exclusive OR(Eor), the potential of each electrode is converted not only to potential for reversing the adjacent electrode corresponding to recording input but also to bring the adjacent electrode corresponding to non-recording input to the same potential. By this signal conversion, only the part of the resistor between adjacent electrodes corresponding to recording input is allowed to generate heat and a predetermined dot can be recorded. Because the adjacent electrode corresponding to non-recording input is driven at the same potential, a stray circuit current can be reduced and eroneous recording can be prevented even when all of electrodes are simultaneously driven.
