Title: Method for correcting camber of core chip
Inventor: MIKUMO KOICHI
IPC: G11B5/127
Filed: 1987-02-20
Abstract: PURPOSE:To properly correct the camber of a core chip meeting the degree of the camber and to improve the reliability thereof by a stage for sticking a thin film of a nonmagnetic metallic oxide by high-frequency sputtering on the recessed surface of said core chip. CONSTITUTION:The core chip 10 which is cambered in a core sliding stage is imposed on a substrate holder 21 of a high-frequency sputtering device 20 and a thin SiO2 film 22' of a target plate 22 consisting of SiO2 is adhered onto the recessed surface 30 of the chip 10. Gaseous Ar from a valve 27 intrudes at a high speed into the crystal lattice of SiO2 and drives the surface molecules of the crystal into the inside springing out the same. The tensile stress inducing the reverse camber is therefore, acts as the thin 22' is formed, by which the chamber is eliminated. The correction meeting the degree of the camber is permitted by controlling the conditions for vapor deposition. The reliability of the core chip is thereby improved.

Title: Manufacture of inorganic thin film
Inventor: FUNAKOSHI NORIHIRO
IPC: H01L21/027
Filed: 1982-03-11
Abstract: PURPOSE:To make it possible to manufacture an inorganic thin film locally containing a metallic impurity without the need for a treatment with aqua regia, by locally exposing a metal thin film laminated on an inorganic thin film. CONSTITUTION:An inorganic thin film is formed on a substrate, and a metal thin film is laminated on the inorganic thin film. Then, the metal thin film is subjected to a local exposure having an intensity sufficient for the metal forming  the metal thin film to move. As a result, the metal forming the metal thin film in the non-exposed region is absorbed in the inorganic thin film in the exposed region, so that the metal is absorbed in almost only the inorganic thin film in the exposed region. By this method, it is possible to manufacture an inorganic thin film locally containing a metallic impurity without the need for a treatment  with aqua regia which may damage the whole of the inorganic thin film.

Title: Subscriber circuit
Inventor: KUSANO YOSHITAKA
IPC: H04Q3/42
Filed: 1992-02-26
Abstract: PURPOSE:To simplify circuit constitution by providing a balance amplifier generating the voltage of inverse polarity at same amplitude and shifting a gain with the feedback resistant value as a value different from a prescribed resistant value. CONSTITUTION:The balance amplifier 1 has large amplification degree. Since resistances R3 and R4 operate as negative feedback resistances, the voltage of a + terminal and that of a - terminal become equal. A four-wire line signal inputted to the + terminal of the amplifier 1 is current/voltage-converted by the amplifier 1 and resistances R1-R6 and it becomes a two-wire line signal, whereby it is outputted to a TiP line and a Ring line. A two-wire/four-wire conversion circuit 2 is composed of an operand amplifier 4 and resistances R7-R10, it multiplies the Tip line and the Ring line by a prescribed resistant value ratio and converts the signal into the four-wire line signal. Thus, the feedback resistant value of the amplifier 1 and resistant values R7-R10 connected between an input terminal and the circuit 2 are made into different values, and the gain of the feedback circuit by the amplifier 1 can be shifted. Then, an AC feedback circuit can be eliminated and circuit constitution becomes simple.
