Filed: 1990-11-02
Abstract: PURPOSE:To improve packaging accuracy by providing a vertically movable first nozzle rod joined with rotary means for rotating a part to a proper mounting angle and a second nozzle rod for holding the part. CONSTITUTION:A nozzle housing 11 is raised by nozzle elevation means 14, and hereby a theta-rotation driving rod 1 and a first nozzle rod 2 are joined together.

Title: Inspection apparatus for circuit board
Inventor: YUHARA YOSHIYUKI
IPC: G01R31/02
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To obtain an inspection apparatus by which the costs of a designing can be reduced by a method wherein a reference signal is oscillated and it is frequency-divided in a frequency-dividing ratio based on an input setting signal so as to be output as a clock signal. SOLUTION: In a clock part 34, a reference oscillation circuit 41 oscillates a reference signal, e.g. at 1MHz, it is frequency-divided into, e.g. 1MHz by a frequency divider 42, and it is frequency-divided further by a programmable counter 43 so as to be output as a clock signal CL. When the frequency divider 42 receives a changeover signal S14 , it frequency-divides the reference signal in a fixed frequency-dividing ratio, e.g. 1/10. When the changeover signal S14 does not exist, the reference signal is not frequency-divided so as to be output to the programmable counter 43. The programmable counter 43 frequency-divides the reference signal in respective corresponding frequency-dividing ratios according to setting signals S21 to S36 from a CPU 21, and the clock signal CL in a duty ratio of about 50% is output only when a clock control signal S13 is output from the CPU 21.  As a result, the CPU 21 can control a measuring timing at a measuring board 33.
