Abstract: An inspection device is a device that inspects the appearance of a target, including: an imaging device configured to image the target from a first direction; an illuminating unit configured to apply light to the target; and a controller configured to acquire a first inspection image by causing the imaging device to image the target to which light is applied from a first position, to acquire a second inspection image by causing the imaging device to image the target to which light is applied from a second position, and to inspect an appearance of the target based on the first inspection image, the second inspection image, and a reference image. The first position and the second position overlap each other when viewed from the first direction.

Abstract: A CRT-matrix type big screen display system having self-emitting type picture cells is provided with a deflection waveform as a sawtooth waveform and a deflection waveform in the other direction as a step deflection waveform crossing the picture cells. Inclination of the scanning line is eliminated so that fluctuations in display brightness thereto are avoided and a satisfactory picture display is achieved. Also in CRT-matrix type big-screen display systems, index elements or cells are provided between sets of primary color cells and in the scanning direction. At least at the start of the scanning operation, the index elements or cells are scanned and the positional information thereof is stored in a memory for use in processing a video signal to achieve a satisfactory picture display.

Abstract: A large area display has a plurality of cathode ray tubes mounted adjacent each other in X, Y matrix and each cathode ray tube includes a plurality of pixels arranged in an X, Y matrix on a front panel and each pixel comprises three horizontally extending stripe-shaped luminous elements aligned in the vertical direction and the front panel of the cathode ray tube is formed with a thinner portion adjacent its outer edge where it joins to the funnel to reduce the spacing between adjacent cathode ray tubes to a minimum to allow the pixels to be viewed over a wider angle.

Abstract: A timer display apparatus is disclosed which has a timer time display member, a memory capable of memorizing a plurality of timer times and a discriminating circuit which compares the memorized timer times in the memory with the present or instant time and then discriminates the timer time of the memorized timer times nearest but after the instant time. Then, based upon the output from the discriminating circuit, the timer time nearest but after the instant time is read out from the memory and displayed on the timer time display member.
