Abstract: A vehicle display apparatus includes an image display panel, a backlight, and a translucent plate. The image display panel displays an image in a display area. The backlight emits a light in a direction from a back surface of the image display panel toward the display area. The translucent plate has a plate shape and is disposed between the image display panel and the backlight. The translucent plate transmits the light emitted from the backlight. The translucent plate has a three-dimensional indicator configured to be visually recognized through the image display panel, and a periphery portion of the translucent plate is disposed out of the display area.

Abstract: A display device for a vehicle includes: a first display unit that displays a real image of first information in a first display portion; and a second display unit that displays a virtual image of second information in a second display portion by projecting an optical image to the second display portion, the second display portion being disposed above the first display portion and transmitting an external image. The display device includes: a light emission unit located adjacent to a side of the first display portion to form a light emission area; and a control unit that changes the light emission area in a guiding direction from the first display portion toward the second display portion during a linking period for linking a particular virtual image display of the second information with a real image display of the first information.

Abstract: A control system for an electric storage system, in which a plurality of pairs of storage batteries and converters are connected in parallel to a power system, includes: a unit that decides charge and discharge of total power by the pairs of storage batteries and converters; and a unit that distributes the charge and discharge power decided by the charge and discharge power decision unit to the pairs of storage batteries and converters. The power distribution decision unit compares the charge and discharge total power with a limit output when conversion efficiency of the converters is equal to or greater than standard efficiency, and decides a running number by which an output of all the pairs of running storage batteries and converters is equal to or greater than the limit output when the charge and discharge total power is equal to or greater than the limit output.

Abstract: An electrical grid control system includes a plurality of power conversion apparatuses each storing active power relationship information indicating a relationship between an active power control level representing a level of control for active power output to an electrical grid, and a connection point frequency being a frequency at a connection point to the electrical grid; and a control apparatus that repeatedly receives information indicating a system frequency measured in the electrical grid, determines the active power control level based on the system frequency, and transmits the active power control level to the plurality of power conversion apparatuses. Each power conversion apparatus repeatedly measures the connection point frequency, receives the active power control level from the control apparatus, and controls the active power based on the measured connection point frequency, the received active power control level, and the active power relationship information.

Abstract: An electronic device includes: a first housing 1; a cover 11 capable of covering a portion of the first housing 1 to be covered; and a waterproofing member 12 placed around the portion to be covered. The cover 11 is displaceable between a closed position at which the cover covers the portion to be covered and an open position at which the cover opens the portion to be covered. The cover 11 is in contact with the waterproofing member 12 when it is at the closed position. Even if the number of terminals increases, since the waterproofing member 12 is provided on the first housing 1, the single waterproofing member can render all of the terminals waterproof. Thus, it is possible to reduce the number of components and to reduce the number of assembling steps.

Abstract: A casing 1, a lid component 11 for covering a terminal 13 disposed in an opening of the casing 1, and a water sealing component 12 disposed around the terminal 13, are provided. The lid component 11 is structured such that a support portion 11h of a fixing portion 11g is rotatably fixed to the casing 1, and a slidable portion 11b slides relative to a lid portion 11a. Thus, a projection 11c is engaged with a recess 14, and a pair of engagement portions 11f engages with a pair of fixed projections 16. Thus, the lid component 11 engages with the casing 1 in three directions, and is held by being pressed against the water sealing component 12. With this structure, an electronic device having a lid component which can be assuredly locked is obtained.

Abstract: A casing 1, a terminal plate 30 that is exchangeably mountable in an opening 23 formed in the casing 1; and a water sealing component 50 disposed around a terminal 31 formed on the terminal plate 30, are provided. A flange 24 is formed inside the opening 23 so as to surround a center of the opening and project toward the center of the opening. When the terminal plate 30 is mounted on the flange 24, an outer side surface of the terminal plate 30 is flush with a surface 21 of the casing in a portion where the opening is formed. With this structure, an electronic device can be obtained that is reliably waterproof and/or dustproof in a connection terminal portion that is exchangeable so as to enhance an expandability.

Abstract: A main device includes fixing portions that fix a holding device to one principal surface thereof and project from the one principal surface. An extension device includes a placement portion on which the main device is placed and a wall portion on which the placement portion is provided in a standing manner. The wall portion that faces the one principal surface, to which the holding device is fixed, in a parallel relation, has such a shape as to not interfere with the fixing portions that fix the holding device of the main device, when the main device is placed on the placement portion. The main device can be mounted on the extension device with the holding device mounted thereon, and time and effort to remove the holding device can be saved when the main device is mounted on the extension device.
