Abstract: PURPOSE:To prevent accidents due to the fault of the device by storing a scale value before and after the performance of the fixed motion of a head part, comparing them, and discriminating as a failure in fixing or the abnormality of a fixing means when the scale value is different more than an allowable range. CONSTITUTION:A head control means 5 moves the head part 4, fixes it at any position by the fixing means 7 of the head part, and simultaneously allows a scale value comparing means 6 to read and store the scale value. After the fixing motion is completed, the means 5 allows again the means 6 to read the scale value and compare with the stored scale value. Then, if the difference of the scale value is within the allowable range, the means 6 discriminates the fixing state as normal, and if it is out of the allowable range, it discriminates the fixing state as abnormal and outputs a signal to the means 5. A driving part control means 8 based on information from the means 5 processes the abnormality. Thus, the accidents due to the fault of the device is prevented.

Title: Selective removal method by applying equipotential
Inventor: TAKADA YUJI
IPC: H05K3/06
Filed: 1989-12-18
Abstract: PURPOSE:To allow the etching of only the surface metal of a work even with a printed wiring board integrated to a high density by using an external power source exclusive of the work and connecting the work to a soln. CONSTITUTION:Metals generate respectively different potentials when the potentials of the metals are measured at the time of melting of the metals. For example, the melting potential of copper is 50mV and the melting potential of nickel is 80mV. The potential of a laminate formed by laminating the nickel on the copper, therefore, maintains 80mV until the nickel melts first when this laminate is melted. The copper is exposed on the surface when the nickel melts completely and, therefore, the melting potential of 50mV is maintained if the treating liquid is thereafter weakened and the surface of the metal is measured. The work 2 is, thereupon, immersed in the treating liquid 3 and the melting potential is applied on the surface metal of the work 2 by using the external power source to maintain the potentials specific to these metals, by which only the desired metal is etched.
