Inventor: HIRANO AKIRA
IPC: G11C19/08
Filed: 1981-06-05
Abstract: PURPOSE:To prevent a conductive part from being damaged and to form an electrode  part by previously applying MgF2 to the surface of a metallic layer forming the conductive pattern of a memory chip, forming a window on the conductive part by dry- etching and then removing MgF2 remaining in the window part. CONSTITUTION:An insulating layer (SiO2) 2 is applied to the surface of a magnetic  garnet crystal layer 1, a conductive layer (Au) 3 is formed on the surface of the layer  2 and the upper and lower surfaces of the layer 3 are coated with Ta.Mo alloy layers  4 to improve and protect the adhesive property of the Au layer 3. Subsequently a protective layer 15 consisting of MgF2 is formed on the layer 4 applied to the upper surface of the layer 3, a driving pattern 6 is formed on the layer 15 through an insulating  layer 5 and an SiO2 protective layer is formed on the surface of the layer 5 including  the pattern 6. A resist pattern is formed on the protection layer 7 and a window 8 is  opened by plasma etching so as to reach the conductive layer. Since the etching speed  of the SiO2 layers 5, 7 is several hundreds times faster than that of the MgF2 layer,  the window 8 is opened without damaging the Au layer. The remaining MaF2 layer is  easily dissolved and removed by dipping the layer in a nitric acid solution.

Filed: 1983-05-18
Abstract: PURPOSE:To increase a combustion amount regulating ratio and to stabilize an air-fuel ratio, by a method wherein either an air amount regulating means or gas amount regulating means is controlled dependently on the load of a burner, and the other is controlled according to a difference between two output signals from a differential pressure signal discriminating circuit. CONSTITUTION:When pressure switching valves 14a and 14b are borught into a first state, PG and PA are applied in pressure guiding holes 13 and 15 respectively, of a differential pressure sensor 12. When the pressure switching valves 14a and 14b are brought into a second state, PA and PG are applied in the pressure guiding holes 13 and 15, respectively, of the differential pressure sensor. Namely, the output of the differential pressure sensor alternately produces an output, corresponding to (PA-PG), and an output corresponding to -(PA-PG) having reverse polarity thereto. A gas pressure proportional valve 10 is controlled by feedback so that an input signal (PA-PG) is brought to zero by means of an air fuel ratio regulating circuit 19 including an integrating computing element. This causes maintaining of PG=PA without being effected by the error of a differential pressure sensor 12 and a differential pressure sensor detecting circuit 16.
