摘要： Grooves for constructing transport passages 12 for transporting semiconductor chips 28 are provided (the grooves are provided in parallel to one another in a number corresponding to quality levels of the semiconductor chips 28). An air blow pipe 27 is provided at a starting end Pa of the transport passage 12 in a transport direction (direction indicated by the arrow in FIG. 7) to give the thrust for moving the semiconductor chips 28 in the transport direction. A large number of air-jetting holes 26 for floating the semiconductor chips 28 are provided through a transport surface. Especially, the air-jetting holes 26 are provided at a terminal end in the transport direction in a number larger than those for the other portions. Thus, the floating amount of the semiconductor chip 28 is maximized at the terminal end. A plurality of slits 29 are provided vertically through a terminal end wall 20a in the transport direction. Accordingly, a transport system is realized, in which the object is transported in one direction while floating the object by means of air. Especially, it is possible to realize the automatic operation for picking up individual objects one by one.

摘要： A parallel light beam is introduced from a collimator lens into through holes defined in a honeycomb-shaped object, and any light emitted from the honeycomb-shaped object is read by a CCD camera through a Fourier-transform lens to produce a Fourier-transform image of the honeycomb-shaped object. The honeycomb-shaped object is tilted such that the axis of the through holes is inclined at a certain angle to the optical axis of the parallel laser beam. If the partitions contain interstices spaced at intervals and light introduced into the through holes passes through such interstices, the Fourier-transform image includes a stripe pattern induced by diffracted light from the interstices. Since the stripe pattern can easily be distinguished from a dot-matrix pattern representing light emitted from the through holes, the interstices contained in the partitions can reliably be detected.

摘要： Disclosed herein is a passage detection apparatus capable of detecting a passage of an object in a specific space. The passage detection apparatus includes a transmitting device, a receiving device, and a shielding member. The transmitting device is provided with a vibration generating source. The receiving device is arranged at the position corresponding to the transmitting device across the specific space. The shielding member has a through-hole, and is arranged so as to be interposed between the transmitting device and the receiving device.

摘要： A lower electrode 4 and an auxiliary electrode 8, a piezoelectric/electrostrictive film 5, and an upper electrode 6 are sequentially arranged in layers on a substrate 1. The lower electrode 4 is continuously formed in a region ranging from a first portion of the thick-walled portion 2 to a thin-walled diaphragm portion 3. The auxiliary electrode 8 is continuously formed in a region ranging from a second portion of the thick-walled portion 2 opposite the first portion to a position on the thin-walled diaphragm portion 3, the position being separated from the lower electrode 4. The upper electrode 6 is formed in such a manner as to overlie the piezoelectric/electrostrictive film 5 and the auxiliary electrode 8. Furthermore, a connection electrode 20 is provided for electrically connecting the upper electrode 6 and the auxiliary electrode 8. Thus, a plurality of paths are provided for electrically connecting the upper electrode 6 and the auxiliary electrode 8. Therefore, even when connection through a certain path is cut off due to fracture of a portion of the upper electrode 6 caused by deterioration in insulating performance of the piezoelectric/electrostrictive film 5, electrical connection between the upper electrode 6 and the auxiliary electrode 8 can be maintained through the remaining path(s).
