Title: Adaptive signal processing unit
Inventor: MIZUUCHI TAKAYUKI
IPC: H04B3/04
Filed: 1992-12-15
Abstract: PURPOSE:To implement adaptive processing effectively by devising the processing unit such that it processes a non-steady signal as a steady signal. CONSTITUTION:A 1st A/D converter 20M converts a major input signal into a digital signal by the oversampling system. A 2nd A/D converter 20R converts a reference input signal with strong correlation with a reduction object signal in the major input signal into a digital signal by the oversampling system. An adaptive filter circuit 40 obtains a signal approximated to the reduction object signal in the major input signal based on an output digital signal of the 2nd A/D converter 20R. A synthesis circuit 30 subtracts an output signal of the adaptive filter circuit 40 from the output digital signal of the 1st A/D converter 20M. The subtraction output signal of the synthesis circuit 30 is fed back to the adaptive filter circuit 40, in which adaptive processing is implemented so that the power of the output signal of the synthesis circuit 30 is minimized.

Title: Pretreating agent for electroless plating and pretreatment of electroless plating using the same
Inventor: YAMADA YOSHINORI
IPC: C23C18/18
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To simplify a pretreatment and to suppress the deterioration of a plating solution by treating the surface of a material body with a pretreating agent for electroless plating, which consists of an alkoxysilane or its partially hydrolyzed condensation material, and after that, plating. SOLUTION: At the time of electroless plating the electrically non-conductive material body, the surface of the material body is pretreated with the pretreating agent for electroless plating, which consists of the alkoxysilane expressed by a formula, Hn -Si(OR)4-n (where, R represents a 1-4C alkyl group and (n) represents 1 or 2) or its partially hydrolyzed condensation material. The alkoxysilane changes to a silica like glass by hydrolysis reaction to be hardened and forms a film on the surface of the material body to be plated. The pretreating agent is rapidly hardened only by being applied on the material body and being allowed to stand to proceed with electroless plating. By heating, the hardening is accelerated to decrease the treating time. As a result, the plating solution is prevented from being absorbed inside of the material body and being consumed.
