Abstract: An uninterruptible power supply includes a plurality of uninterruptible power supply modules each including a power converter, an input/output module that outputs power converted by the power converter to an outside of the uninterruptible power supply, and a disconnection module including a housing that houses disconnection switches that electrically disconnect each of the plurality of uninterruptible power supply modules individually.

Abstract: An uninterruptible power supply includes disconnectors that perform a disconnection operation to electrically disconnect a plurality of uninterruptible power supply modules individually. Each of the disconnectors includes a connection conductor that electrically connects a first conductor to a second conductor, and a moving member mechanically moving the connection conductor in a direction in which the connection conductor approaches and contacts the first conductor and the second conductor, and a direction in which the connection conductor is spaced away from the first conductor and the second conductor.

Abstract: In an uninterruptible power supply, first connection members that connect input side-switches of a plurality of uninterruptible power supply modules to each other and that connect output-side switches of the plurality of uninterruptible power supply modules to each other, and second connection members connected in parallel to the first connection members are disposed at positions accessible from a front side of the uninterruptible power supply modules.

Abstract: A food storage and delivery device is formed of a reservoir for food items, a holding and transferring section situated adjacent to the reservoir, an ascending section for moving the holding and transferring section, and a controlling section for controlling the device. After positioning the holding and transferring section to one side of the storage and delivery sections at a predetermined vertical level by means of the ascending section based on a delivery command, the food item is delivered from the storage and delivery section to the holding and transferring section to hold the food item temporarily. After positioning the holding and transferring section to a vertical level corresponding to a delivery portion, the temporarily held food item is delivered to the delivery portion. The food items can be automatically and quickly delivered.

Abstract: A storage and delivery device for packed foods retained in containers is formed of a plurality of shelf cases each having a plurality of vertically oriented shelves for retaining the containers thereon, a storage shed for retaining the shelf cases therein and having a cyclic-moving device for cyclically moving the shelf cases horizontally along a horizontal closed loop, a processing device for processing the packed foods in the containers, and a robot. When an order is received, the robot takes out the container from the shelf of the shelf case and transfers the container to the processing device for processing the packed food. A storage room retains the storage shed, the processing device and the robot. The containers with the foods can be stored and automatically delivered after processing.
