    摘要: Emission of a surface light source device is prevented from having brightness-unevenness, having a uniformalized brightness. A plurality of LEDs are disposed opposite to an incidence face of a light guide plate. A reflection sheet is disposed along a back face of the light guide plate while a cover member for the LEDs is disposed on an emission face in the vicinity incidence face. A light diffusion member, first and second light control members are laminated disposed along a part of the emission face which is not covered by the cover member. A top of the reflection sheet is secluded a predetermined distance L from the incidence face to provided a part which is not covered by the reflection sheet in the vicinity of the incidence face. The predetermined distance L may be given, for example, by L=2h·tan θ (where h=thickness of light guide plate at incidence face, θ=critical angle at an interface between light guide plate and air.

    摘要: In this parallel gripper suitable for gripping a work for a robot or the like, in which a pair of fingers are opened and closed by keeping the parallel condition between them by the transmission of the driving force of a fluid pressure actuator to the fingers by means of a power transmission mechanism, use is made of a pair of pistons, that are relatively slidable in a single cylinder bore under the action of fluid pressure, as the fluid pressure actuator, thereby obtaining substantially twice as large gripping force as in the case of empolying a single piston. Further, simplification in constitution and reduction in weight of the parallel gripper are achieved by constructing the gripper so as to supply a pressurized fluid to the pressure chamber formed between the pair of pistons in the cylinder bore, and by transmitting the driving force of both pistons that are driven in the mutually opposite directions to the fingers by means of a simple power transmission mechanism which employs levers as its principal components.
