Abstract: A device for inspecting waterproofness of an object includes a lower jig and an upper jig configured to support the object to be inspected, inspection modules configured to contact an outer surface of the object, and an air compressor configured to supply air to the inspection modules. Each of the inspection modules includes a jig that is configured to contact the outer surface of the object and defines a chamber configured to communicate air, a valve defining a passage in communication with the chamber, an air supply line connecting the valve to the air compressor and configured to guide air to the passage, and a pressure sensor connected to the valve and configured to detect an air pressure in the passage.

Abstract: Provided is an apparatus for testing waterproofness of a half-finished product, wherein the apparatus is configured to form a chamber space such that areas of holes and parts of the half-finished product are separated from each other, and high-pressure air is injected into the chamber space, thereby performing a waterproofness test. In addition, a sliding block is provided such that a hole blocking means blocking the holes of the half-finished product is moved forward and backward through engagement and disengagement of a body and a cover without requiring a separate power, and the apparatus includes the body, the cover, a sealing means, and a hole blocking means including a sliding block moved in a lateral direction of the half-finished product, a blocking member blocking a side hole of the holes, and a pushing member pushing the sliding block to be moved forward when the body and the cover are combined.

Abstract: In order to suppress facility cost and improve convenience of input and output of data, a programmable display device includes a cradle section connected to an apparatus to be controlled, and a tablet section attachable and detachable to/from the cradle section. The cradle section and the tablet section transmit and receive information therebetween through short-distance radio communication.
