Abstract: PURPOSE:To obtain a titled head having reduced magnetostriction and high output by incorporating specified wt% each of Al and Si into a metallic magnetic film. CONSTITUTION:Nonmagnetic substrates 1 and 1' having specified thermal expansion coefficients are provided, and a metallic magnetic film 2 contg. 5.5+ or -1.0wt% Al and 9.5+ or -1.0wt% Si is formed on the substrate 1by sputtering. In addition, SiO2 is sputtered to form a film 3, and a metallic magnetic film 2', an SiO2 film 3', and a metallic magnetic film 2'' are successively formed. Then a glass film 4 is formed on the metallic magnetic film 2'' by sputtering low-melting point lead glass. Similar low-melting point glass film 4 is formed on the other substrate 1'. Both substrates 1 and 1' thus obtained are welded and butted with the glass film 4 to form a core body 7. Then the body 7 is cut of a specified azimuth angle to obtain core half bodies 6 and 6 whose cut surfaces are lapped, sputtered with gap spacers 5 and 5', heated and bonded to obtain the metallic magnetic thin film head.

Title: Display device
Inventor: KANEDA ISAO
IPC: G09G3/28
Filed: 1985-08-26
Abstract: PURPOSE:To secure such an image that is excellent in a contrast, by using a plasma display as a driving source of a liquid crystal display. CONSTITUTION:A plasma display (PD) having a discharging gap 5 and a liquid crystal display (LCD) having a liquid crystal layer 12 are unitized in one, constituting a display device. The plasma display constitutes a series circuit for a condenser in terms of equivalence, therefore if a pulse current passes through, in conformity with the polarity, a wall voltage in proportion to integral but inverse proportion to capacity of the pulse current is left behind at both ends of each condenser. Since each terminal voltage of these condensers is relatively high, it printed on the liquid crystal display upon being divided by impedance. With this constitution, such a hybrid structural display device as being suitable for either day and night, beside a large screen is securable.
