摘要:
A thin-film magnetic head constructed in the manner that a magnetic circuit is composed of a base of magnetic material and a thin-film magnetic core layer, which form an operating gap at the front end thereof and a rear junction at the rear end of the magnetic core layer, and a conductor layer forming a winding is provided between the base and the magnetic core layer. The magnetic core layer has a larger width at the portion where it crosses over the conductor layer, than at the operating gap portion, whereby magnetic fluxes generated by electric current flowing through the conductor layer are effectively passed through the magnetic core layer and so recording efficiency is improved.

This invention provides a thin film magnetic head composed of at least one conductive body layer formed in a magnetic material substrate with grooves therein, each groove being filled with a non-magnetic material, an insulating layer formed on the face of the magnetic material substrate including the conductive body layers, and a magnetic material layer formed on the insulating body layer. To precisely form the groove, an electrolytic etching process of the substrate and an annealing process of the substrate surface layer are combined to provide an straight-line property of the groove and the groove section, circular in arc, with better reproducibility.

A bias conductor layer for a bias current path extends through the gaps of a plurality of unit thin-film magnetic heads, which are placed side by side over signal conductor layers. A spacer layer is provided between upper and lower magnetic material layers and extends over the area including the gaps formed between the bias conductor layer and the signal conductor layers, and an additional thickness of spacer material is provided at the gaps so that the distance between the upper and lower magnetic material layers is increased and therefore magnetic short-circuiting is avoided.

There is provided a vehicle system, including an electromobile having a fuel cell power generator mounted therein, and a predetermined mobile unit jointable to the electromobile, such that cogeneration within the mobile unit can be realized even during the travel of the electromobile. Via a joint section 30, a vehicle 10 including a fuel cell 13 as a source of motive power is jointed to a mobile unit 20 capable of travelling and at least including a storage battery 23 and a water tank 25. The water produced in the fuel cell 13 is recovered by a water recovery section 21 via the joint section 30. The heat produced in the fuel cell 13 is recovered by a heat recovery section 22 via the joint section 30. The recovered water is warmed up with the recovered heat, and thereafter stored in the water tank 25. The hot water stored in the water tank 25 is utilized as hot water to be used for controlling the temperature of the mobile unit 20 or supplied as hot water. Any excess electric power generated by the fuel cell 13 is stored in the storage battery 23, and supplied onto electric wiring within the mobile unit 20.

摘要:
On a silicon substrate is formed a silicon dioxide film and then hemispherical grains made of silicon, each having an extremely small diameter, are deposited thereon by LPCVD. After annealing the hemispherical grains, the silicon dioxide film is etched using the hemispherical grains as a first dotted mask, thereby forming a second dotted mask composed of the silicon dioxide film. The resulting second dotted mask is used to etch the silicon substrate to a specified depth from the surface thereof, thereby forming an aggregate of semiconductor micro-needles. Since the diameter of each of the semiconductor micro-needles is sufficiently small to cause the quantum size effects as well as has only small size variations, remarkable quantum size effects can be obtained. Therefore, it becomes possible to constitute a semiconductor apparatus with a high information-processing function by using the aggregate of semiconductor micro-needles (quantized region).
