Title: Plating method
Inventor: KANO OSAMU
IPC: H05K3/24
Filed: 1987-04-06
Abstract: PURPOSE:To surely apply partial plating and to facilitate the handling of an engaging member by using water-expandable rubber as the engaging member to be press-fitted in and engaged with the part not to be plated in partial plating. CONSTITUTION:For example, a penetrating hole 1a is formed in a substrate 1 as the material to be treated, the peripheral wall of the hole 1a must not be plated, and a plated film is formed on both principal planes of the substrate 1 except the peripheral wall. In this case, a dried plug 2 consisting of water- expandable rubber and having a diameter same as or somewhat smaller than that of the hole 1a is inserted in the hole 1a. The plugged substrate 1 is then dipped in water, and the plug 2 is cubically expanded and pressed on the peripheral wall of the hole 1a. Under such conditions, the substrate 1 is dipped in a plating bath, and plated films 4a and 4b are formed by electroless plating. In this case, since the plug 2 is surely pressed on the peripheral wall of the hole 1a, a plated film is not formed on the peripheral wall. In addition, the plug 2 contracts by the drying of the substrate 1 after treating, and hence is easily detached.

Title: Signal sampling circuit
Inventor: KUBOTA KIYOMICHI
IPC: G06F3/05
Filed: 1994-04-22
Abstract: PURPOSE:To attain high performance with high stability and fidelity by adding a polarity inversion arithmetic circuit, a delay phase generating circuit, a comparator and an AND gate circuit to a sampling timing circuit so as to eliminate an error component from an output waveform entirely. CONSTITUTION:When an analog input signal 40 is given to the circuit, in which a waveform 11 appears, which comprises a semicircular invalid waveform 12 located to the left and the right end and two valid component waveforms 11 having rectangular positive and negative components in pairs. When the positive valid component is received, a SW of a sampling SW circuit 2 is thrown from the position NC to the NO and the analog input signal 40 is given to an A/D converter 3. In this case, an output waveform 29 of an AND gate 24 is outputted as a sample timing signal. Furthermore, since only a true value component 16 synchronously with a trigger wave being a waveform 29 outputted from the AND gate 24 is outputted from an output terminal 4 of the A/D converter 3, the error component of the invalid waveform 12 is not outputted. Thus, the A/D conversion accuracy as the signal extract circuit is high.

Title: Control method of oxygen concentration in combustion waste gas
Inventor: HIROI KAZUO
IPC: F23N5/00
Filed: 1983-05-16
Abstract: PURPOSE:To quicken the response of an oxygen concentration control system, by a method wherein a change in an oxygen concentration set value is promptly reflected in an air excess rate mu in a form in which the change is backed up with a theoretical formula. CONSTITUTION:Depending upon the output of an oxygen concentration setter 24, a muS computer 21 performs computation of muS=A/(A-O2S), wherein A is oxygen content in the air, and O2S is an oxygen concentration set value, to find an air excess rate muS. Based on a signal MV(DELTAO2), representing a deviation amount DELTAO2, from an oxygen concentration regulating meter 5, an output muS of the muS computer 21, and a constant A, computation of mu=muS+MV(DELTAO2)mu<2>S/A is executed through multipliers 20 and 25 a divider 26, and an adder 22, and this obtains a value mu to which a reference air excess rate muS in relation to a combustion system is corrected. This enables control of combustion at a low oxygen concentration, and permits formation of a combustion system, which is effective to energy-saving and prevention of environmental pollution, through ensurance of an optimum air-fuel ratio.
