Abstract: An alkali-earth vanadate compound functioning as a phosphor is a reaction product of vanadium oxide and an alkaline-earth metal or salt thereof.

Abstract: In a state in which any one of selection buttons is selected (state in which a color is reversed), a touch panel in a controller is operated, and, the selected state of the selection button is released when an operation signal from the above controller is corresponding to a moving trajectory from a gray zone to another gray zone through a cancellation zone. Thereby, unnatural feeling at operation caused by distance between a finger position on the touch panel of the controller and a position of the selection button in the selected state is reduced or eliminated.

Abstract: A rearview mirror has a housing. The housing includes a front surface facing a driver's seat, a rear surface at the opposite side of the front surface. The housing has a slot for receiving a recording medium that stores predetermined data. The slot has a width, which is larger than a width of an insert potion that of the recording medium. The recording medium is inserted into the slot at an arbitrary position in the width direction of the slot. An interface performs at least one of reading of data from the recording medium and writing of data to the recording medium. The interface includes a detector, a data input/output unit and a moving mechanism. The detector detects insertion of the recording medium into the slot. The data input/output unit swaps data with the recording medium. The moving mechanism moves one of the data input/output unit and the recording medium to a position where the data input/output unit faces the recording medium.

Abstract: A portable device is detachably attached to the dashboard of a vehicle. The image of the condition outside the vehicle is taken by an infrared camera. The taken image is shown on a display, which is part of the portable device. The infrared image shown on the display is projected onto a translucent screen.
