Abstract: Provided is a cement composition that has high fluidity (for example, a 0-drop flow value of 200 mm or more) before curing and exhibits high compressive strength (for example, 320 N/mm2 or more) after curing. The cement composition includes a cement, a silica fume having a BET specific surface area of from 10 m2/g to 25 m2/g, an inorganic powder having a 50% cumulative particle size of from 0.8 ?m to 5 ?m, a fine aggregate having a maximum particle size of 1.2 mm or less, a water reducing agent, an antifoaming agent, and water. The ratio of the cement is from 55 vol % to 65 vol %, the ratio of the silica fume is from 5 vol % to 25 vol %, and the ratio of the inorganic powder is from 15 vol % to 35 vol % in the total amount of 100 vol % of the cement, the silica fume, and the inorganic powder.

Abstract: A hood attachment jig includes a holding member whose diameter is increasable and that holds an endoscope hood in a state where the holding member is inserted into the endoscope hood; a diameter increasing member that increases the diameter of the holding member by entering the holding member, so that the diameter of the endoscope hood increases; and a push-out member that, when an attachment operation is performed in a state where a tip portion of the endoscope enters the holding member with the increased diameter, pushes out the holding member and the endoscope to separate the holding member and the endoscope from the diameter increasing member so that the endoscope hood, a force of restitution of which reduces the diameter of the holding member, is brought into contact with an outer circumferential surface of the tip portion of the endoscope and further pushes out the endoscope to detach the endoscope from the holding member so that the endoscope hood is attached to the endoscope tip portion.

Abstract: An image display device comprises multiple gate lines each of which corresponds to each pixel line along the vertical directions in the display panel, and each of which transmits a scan signal to the pixels of each pixel line. Transmission directions of the scan signals of each two adjacent gate lines are opposite to each other. Accordingly, even though the waveform distortion of the scan signal causes display unevenness between the near side and the far side of the transmission direction of the scan signal in each pixel line, the direction of the gradation of each two adjacent pixel lines corresponding to each two adjacent gate lines are opposite to each other. Thus, the display unevenness of the display panel is totally balanced regardless of the size of the display panel, so that the display unevenness of the display panel can be reduced.
