  • Patent number: 10495796
    Abstract: There is provided a near-infrared cut filter which has a visible light transmitting property and a near-infrared shielding property both at high levels by that its transmission spectrum has a steep inclination in the vicinity of the boundary between the visible light and the near-infrared, and which can also be sufficiently reduced in size and thickness. The near-infrared cut filter has a near-infrared absorbing layer which contains a near-infrared absorbing dye containing at least one dye in which a condensed ring structure containing at least a benzene ring and a ring having nitrogen atom is bonded to both sides of a squarylium skeleton and which have a carboxylic acid amide structure at a second position of the benzene ring (where the carboxylic acid has a substituent having 5 to 25 having one or more branches), and a transparent resin with a refractive index of 1.45 or more.

  • Publication number: 20150234680
    Abstract: A task control unit executes a task according to execution request information for the task, which task is registered using a function provided by task control unit. The task control unit separately controls a task (P-Task) whose execution time is set by a programmer and a task (S-Task) whose execution time is set by a system so that the tasks do not interfere with each other. The task control unit executes plural S-Tasks while complying with their execution periods. By controlling tasks by the foregoing methods, energy is saved and a network load is reduced.
