摘要:
A gallium arsenide diode is disclosed which has a very thin resistive layer of a metal oxide, typically titanium oxide, formed annularly on a semiconductor substrate across the exposed annular periphery of a p-n junciton. The titanium oxide layer has a sheet resistance of not less than 10 kilohms per square and creates a Schottky barrier between itself and the neighboring n type region of the substrate. The titanium oxide layer can be formed by first vacuum depositing titanium on the substrate and then heating the titanium layer.

A first insulation film is made of a silicon material and is provided on a semiconductor base. A second insulation film is made of an organic material and is provided on the first insulation film. The second insulation film is thicker than the first insulation film. A third insulation film is thinner than the second insulation film and is provided on the second insulation film. The third insulation film is made of a silicon material and has a moisture resistance property. A fourth insulation film is made of an organic material. The fourth insulation film is provided on the third insulation film to prevent a damage on the third insulation film. A wiring layer is provided on the fourth insulation film.

A current detector comprising a current-path conductor assembly and a Hall generator assembly. The current-path conductor assembly includes a sheet-metal current-path conductor and a plastic conductor holder molded in one piece therewith. The Hall generator assembly includes a Hall generator in the form of a semiconductor chip mounted to a metal-made mounting plate, a set of leads electrically connected to the Hall generator, and a plastic encapsulation enveloping the Hall generator and parts of the leads. The Hall generator assembly and the current-path conductor assembly are combined by bonding together the encapsulation of the Hall generator assembly and the conductor holder of the current-path conductor assembly. The conductor holder and the encapsulation are shaped in interfitting relationship to each other, so that when they are united, the Hall generator is positioned to generate a Hall voltage in response to a magnetic field due to the current flowing through the current-path conductor.

A novel pillar is provided. The pillar having a longitudinal axis and first and second ends, an outer skin, an extruded support structure disposed within the outer skin, with the support structure including multiple cells arranged along the longitudinal axis for support of longitudinal loads, and a tension bar disposed at least partially within the extruded support structure. The outer skin and extruded support may include structural plastic, and the extruded support structure may be separately insertable into the outer skin. However, in an alternative embodiment the outer skin and extruded support structure are co-extruded as a single monolithic piece.

A current detector comprising a Hall generator assembly and a current-path conductor assembly. The Hall generator assembly includes a Hall generator in the form of a semiconductor chip mounted to a metal-made mounting plate via a sheet of magnetic material such as Permalloy. A plastic encapsulation envelops at least parts of all the components of the Hall generator assembly. The current-path conductor assembly includes a sheet-metal current-path conductor and a plastic holder molded in one piece therewith. The Hall generator assembly and the current-path conductor assembly are combined by bonding together the encapsulation of the Hall generator assembly and the conductor holder of the current-path conductor assembly into a unitary casing for the current detector. A covering of Permalloy or the like envelopes the casing.
摘要:
A frameless sliding door system for a television cabinet stand having a top board coupled to two vertical guide mounts. The frameless sliding door system has two doors, each door having top and bottom bearing rail mechanism that permits the doors to move horizontally away and towards one another, but fixes the movement of the doors in other directions. Other features are disclosed.

An encoder unit comprising an object to be detected having a track having a first region with a magnetization pattern at a predetermined pitch and a second region having no periodic magnetization pattern, and a detector having a magnetoresistance effect element arranged in the direction which intersects the direction of the magnetic flux of the magnetization pattern and in opposed relationship with the object to be detected. The encoder unit is simple in construction yet capable of detecting the position of the object to be detected with a higher degree of accuracy than conventional encoders.

Magnetic thin films are formed on two base plates in relation to tracks of a recording medium. After a non-magnetic thin film is disposed on the magnetic thin films, the two base plates are joined via the non-magnetic thin film to form a magnetic gap, so that a magnetic head is fabricated. The magnetic head can be mass-produced in a simple process with uniform quality, and offers a small area of the surface opposite to each other in adjacent recording and/or reproducing portions, so that crosstalk is reduced.

A magnetoresistive effect thin film magnetic sensor has a temperature compensating magnetoresistive effect (MR) element arranged non-parallel to a signal detecting MR element to prevent the temperature compensating MR element from being influenced by an external magnetic signal field. Alternatively, it has an L-shaped temperature compensating MR element arranged closely to the signal detecting MR element to prevent the temperature compensating MR element from being influenced by the external magnetic signal field. It further has a magnet member arranged closely to or in contact with the temperature compensating MR element to enhance a positional precision of the temperature compensation and reduce a time lag.
摘要:
The present invention is directed to improvements in a perpendicular magnetic recording-reproducing head. One of the improvements comprises the use of a magneto-resistive effect element to form the main pole of the magnetic head. This feature of the invention enables a stable and faithful reproduction of information recorded in a magnetic recording medium up to the shortest wavelength and to obtain a sufficiently large reproducing output signal. Another improvement comprises the use of such magneto-resistive effect elements in layers. The multilayer structure permits production of a large reproducing output and also an optimum S/N ratio even if the width of track is small.
