A current-control-type light emitting display in which a reverse current can be supplied to a light emitting element without requiring a negative power supply and without being passed through a forward drive section. An image sensor and a method for manufacturing an image sensor that have a relatively large process margin, which may reduce andor eliminate restrictions in downscaling an image sensor. The slide arm automatically locks relative to the base when the slide arm is moved to the retracted position. In one embodiment, the mast, arms andor elbows may be tubular members made from a composite material that is sufficiently elastic to absorb forces to arrest a falling person, but sufficiently resilient to deform and return to its original configuration . In addition, or in another embodiment, the annotations can be searched based on a user’s location within the electronic document. The program code conversion apparatus determines which types of IR nodes to generate in an intermediate representation of subject code to be translated.
