摘要： A pressure container that easily fixes a sample or installs various measurement sensors onto a material tester before initiating various tests under an ambient pressure using the material tester, the container including a cover member that is mounted on the bottom surface of an upper loading frame plate with the loading cylinder of the material tester penetrating the center thereof, a bottom member that is mounted on the top surface of a lower loading frame plate with the platen of the material tester penetrating the center thereof, and a cylindrical side wall member having the same outer diameter as the cover member and the same inner diameter as the bottom member. The side wall member is disposed so as to slide vertically around the bottom member and can be detachably fixed to the cover member in its uppermost position in which the side wall member touches the cover member. This type of pressure container enables various preparatory work to be conducted without removing the loading frame plates from the material tester after a sample inside the pressure container has been adhered directly to the loading cylinder of the material tester.

摘要： A blue-violet semiconductor laser device has a first p-electrode formed on its upper surface and a first n-electrode formed on its lower surface. A red semiconductor laser device has a second n-electrode formed on its upper surface and a second p-electrode formed on its lower surface.

Solder films are partially formed on the upper surface of the first p-electrode in the blue-violet semiconductor laser device. Two of the solder films are formed with a predetermined distance between them on the upper surface of the first p-electrode. This results in a portion of the first p-electrode being exposed.

摘要： A high-quality keyboard device for a keyboard instrument, which can be manufactured by a simplified manufacturing process and at reduced manufacturing costs. A keyframe is formed by a molded piece of a synthetic resin. A plurality of front rail pins and a plurality of balance rail pins are arranged in a juxtaposed manner in a left-right direction at a front part and a central part of the keyframe in a front-rear direction. A plurality of keys are made of wood and each have a balance rail pin hole formed in a central portion thereof in the front-rear direction. A first reinforcing member and a second reinforcing member are made of metal and provided in the vicinity of the balance rail pins and the front rail pins for reinforcement of rigidity of the keyframe. The keys are swingably supported on the keyframe in a state where the balance rail pins are each engaged with the balance rail pin hole associated therewith and at the same time the keys are prevented from being swung in the left-right direction by the front rail pins associated therewith.
