Abstract:
PROBLEM TO BE SOLVED: To provide a door locking and unlocking device which enables the free adjustment of the operating time and timing of the maintenance and release of a released state of a locking mechanism. SOLUTION: A release lever 8 for restricting the motion of an open lever 7 for moving a sliding claw 4 is provided, and connected to a movable iron core 12a of a solenoid 12. The release lever is disengaged from the open lever in an on-state, and engaged with the open lever in an off-state. A locking lever 10 is provided to control the motion of the release lever with respect to the open lever in the off-state, and connected to a movable iron rod 13a of a solenoid 13. The locking lever is disengaged from the release lever in the on-state, and engaged with the release lever in the off-state. A tongue piece portion 2a of a cylinder lock 2 can simultaneously bring about the disengagement of the release lever from the open lever, and the disengagement of the locking lever from the release lever.

Abstract:
PROBLEM TO BE SOLVED: To provide a method that can exactly and safely carry out the harvesting/processing operations for bulbous vegetables such as scallion as well as can achieve a large labor saving. SOLUTION: A net 20 is laid in the ground and seed scallions are planted on the net 20 and allowed to grow. At this time, the roots 31 growing from the scaly bulbs 30 pass through the meshes of the net 20 and expand into the ground, but the branched new/grown bulbs cannot pass through thus the root parts come together in the lower part of the net 20, while the bulbs 30 stay on the upper part of the net 20. Since the grown bulbs are fixed to the net 20 with their own roots 31, thus they can be easily harvested only by pulling up the net 20 from the ground. The harvested scallions are introduced into the processing device as the bulbs are fixed to the net 20, and the leaf and stem part 32 are cut off from the bulb part 30 with the rotary blades 47a, 42a set on the position apart from the net face by a prescribed distance.

Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk polishing device which can uniformly and smoothly polish the reading face of an optical disk and is superior in the polishing efficiency and durability of a polishing element. SOLUTION: The optical disk polishing device comprises a doughnut-shaped polishing element 20 shown in the figure; a polishing element rotating mechanism rotatably holding the polishing element 20; a disk rotating mechanism rotatably holding the optical disk 10; a drive part for driving at least any one of the polishing element rotating mechanism or the disk rotating mechanism; and a disk pushing mechanism for pushing the optical disk 10 to the disk rotating mechanism. The center of the polishing element 20 is positioned more inside than the outer periphery of the optical disk 10, and the outer periphery of the polishing element 20 is positioned more outside than the outer periphery of the optical disk 10.
