A semiconductor device comprises a semiconductor element and a support body made of a stack of ceramic layers having a recess in which electrical conductors are electrically connected with the semiconductor element, wherein at least a part of a top face of a recess side wall is covered by a resin, thereby providing a light emitting device. The invention can include first and second resistors having one end of each of the resistors, whose resistances are different, connected to a power supply terminal to which a power supply voltage is supplied. A controller is provided for automatically activating the spray nozzle assembly in accordance with user selected settings. The apparatus then derives subsequent screen coordinates for the display of AR in relation to other real-world object points based on the calibration data. If a disparity is detected, and if the disparity is determined to be greater than some threshold, an allocation module resizes the tiles for the next frame. An anesthetizing agent and a euthanizing agent are dispensed from the canister when the dispensing nozzle is engaged to the valve.
