Abstract: A probe testing apparatus reads the surface shape of a contact pad in pressure contact with a contact probe, and differentiates the read surface shape to extract a multiplicity of flat parts. Next, the probe testing apparatus complements the multiplicity of flat parts to generate a reference shape, and subtracts the reference shape from an averaged surface shape to detect a plurality of recesses having a predetermined depth or more. Next, the probe testing apparatus selects one from the plurality of recesses corresponding to reference information, enlarges the selected recess outward by predetermined dimensions, and subtracts the reference shape from the initial surface shape at the position of the enlarged recess to detect an impression of the contact probe. Finally, the probe testing apparatus determines from the position and depth of the detected impression whether the contact probe is acceptable or defective.

Abstract: The key-less entry system of the present invention comprises a transmitter for transmitting a door lock signal, and a vehicle onboard unit for executing a door automatic lock by detecting that a driver side door has made a transition from an open state to a closed state after reception of the lock signal. Accordingly, once the onboard unit is set to automatic lock mode by operating the transmitter, there is no need to again operate the transmitter and transmit a lock request after finishing work, but the door lock is automatically executed when the door is closed.

Abstract: In a visual inspection method and a visual inspection apparatus, a picture processing unit converts an original picture, which is obtained by taking a photograph of a BGA illuminated by a ring illuminator from above, by using a camera, and labels a binary picture obtained by this binary conversion. Then, it forms a circumscribing rectangle circumscribing an outer circumference of a labeling picture obtained by the labeling, and inverts a labeling picture within the formed circumscribing rectangle, and removes a portion of a region formed by the outer circumference and the circumscribing rectangle in a picture obtained by the inversion, and then generates an inspection picture by adding a picture obtained by the removal to the labeling picture, and accordingly judges a pass or rejection of the inspection target sample based on the generated inspection picture. Thus, the appearance inspection can be carried out at a high accuracy irrespectively of a low cost.

Abstract: Two of four light sources have canceling characteristics with respect to color nonuniformity, and the other two light sources have canceling characteristics with respect to color nonuniformity. A light emission stop detector detects that each of the light sources stops emitting light by blowing its bulb, for example, and feeds, if a certain light source stops emitting light, information indicating that the light source stops emitting light to an energization controller. The energization controller stops, when it receives the information indicating that a certain light source stops emitting light, the energization to a light source paired with the certain light source and puts out the light source.
