Filed: 1981-11-16
Abstract: PURPOSE:To realize a simultaneous production of plural magnetic heads having extremely small track widths with a small number of processes of production, by forming a closed magnetic circuit of a magnetic thin film having high magnetic permeability on a substrate of a nonmagnetic rigid body. CONSTITUTION:A winding window hole 8 is formed on a substrate 5 of a nonmagnetic rigid body. The substrate 5 uses a plate of nonmagnetic ferrite, glass, alumina, etc. with its well polished surface. A magnetic thin film 6 of high magnetic permeability such as a ''Permalloy  '' or amorphous film, etc. is formed on the substrate 5 with <=2mum thickness. Then both gap 7 and external form of a closed magnetic circuit 6A are formed with an etching process. The substrate 5 including the circuit 6A is cut, and the gap surface rubbing on a magnetic recording medium is polished. Then a winding is wound around the gap surface. Thus an annular thin magnetic head is obtained with a small track width. In such a way, it is possible to produce a number of magnetic heads by forming a number of closed circuits at one time on the same substrate.

Title: Small-sized fluorescent lamp
Inventor: TAGAWA KOJI
IPC: H01J61/10
Filed: 1990-07-13
Abstract: PURPOSE:To enhance the brightness and life by using an electrode in which a metal mesh holding an emitter material is disposed on the inner surfaces of electrode bases connected to each other at an opening angle within 3O deg., and enhancing the sealing pressure of rare gas. CONSTITUTION:The sealing pressure of rare gas is 80Torr-130Torr, and an electrode 3 has a constitution in which two electrode bases 31 are connected to each other at an opening angle within 3O deg., and a metal mesh 32 holding an emitter material 33 is disposed on their inner surfaces. Thus, the emitter material can be applied in a large quantity, the metal mesh is stronger than a filament coil. Further, as the opening angle of two electrode bases is within 3O deg., the scattering of the emitter material is suppressed, and a bulb becomes difficult to black. By enhancing the sealing pressure of rare gas, the heat conduction of the gas is suppressed, and the temperature rise after lighting is hastened to promote the evaporation of mercury. Thus, the lighting efficiency is improved to enhance the brightness, and the lighting life and the brightness characteristic can be compatible.
