  • Publication number: 20100119655
    Abstract: To provide a muscular protein denaturation inhibitor which is effective only in a small addition amount because of exerting an excellent effect of inhibiting heat denaturation and freeze denaturation of fish meat-origin muscular proteins, shows almost no taste as a solution, has been approved as a food additive, also has been employed as a component in supplements due to its health-promoting effects, and is safe to the human body. A muscular protein denaturation inhibitor characterized by containing a citric acid salt as the active ingredient and being capable of inhibiting heat denaturation and/or freeze denaturation of fish meat-origin muscular proteins.

  • Patent number: 7061508
    Abstract: A method of loading a pallet that begins by showing a plan view of the pallet on a display screen. The direction and patterns of articles to be placed on the pallet are shown in the plan view. The pattern of articles is then moved to a selected position in the plan view of the display screen. The layout of articles is determined by changing the direction of the pattern to a selected direction. Using this method, positioning of goods on a pallet is done on the basis of the pallet and previously loaded articles. Once the pattern of articles has been determined, the given tier of the pallet is generated.

  • Patent number: 6837741
    Abstract: A connector having a connector main body including a base and a plurality of signal terminals and a plurality of ground terminals both fixed to the base; and a cable positioning member made of conductors for positioning a plurality of cables relative to the connector main body, the cable positioning member including a plurality of securing portions at which the cable positioning member is secured to the ground terminals, and a cable holding portion including a plurality of outer conductor holding portions adapted to hold an outer conductor protruding from the end of each cable and a plurality of insulating layer holding portions adapted to hold an insulating layer protruding from the end of each cable. The cable positioning member is electrically contacted to the ground terminals at the securing portions and to the outer conductors at the outer conductor holding portions.

  • Patent number: 6519507
    Abstract: A method of teaching a robot off-line having a traveling axis, by which the final position and final posture are determined when a robot having a traveling axis stops at an arbitrary position on a traveling axis. The method is able to take an arbitrary posture at the arbitrary position, change from the arbitrary position and arbitrary posture, and move a control point of the robot until it agrees with a movement target point. This position on the traveling axis of the robot is determined so as to minimize the distance between a coordinate origin of the robot a movement target point.
