摘要:
A precursor sol of aluminum oxide contains a polycondensate formed by the hydrolysis of an aluminum alkoxide or an aluminum salt, a solvent, and an organic aluminum compound having a specific structure. An optical member is produced by a process including a step of immersing an aluminum oxide film in a hot water with a temperature of 60° C. to 100° C. to form a textured structure made of aluminum oxide crystals, the aluminum oxide film being formed by feeding the precursor sol of aluminum oxide onto a base.

摘要:
If connection postures of a first and a second housings (10, 40) are inclined from proper ones at a final stage of a connecting process of the first and second housings (10, 40,) pressing portions (73) of a lever (60) press pressable portions (29) of the first housing (10) to correct the connection postures of the first and second housings (10, 40). A mutual connection force of the first and second housings (10, 40) reaches a maximum value when an operable portion (61) of the lever (60) is located at a position near the rear surface of a cover (12) or overlapping the rear surface of the cover (12) before the pressing portions (73) press the pressable portions (29) in the connecting process of the first and second housings (10, 40).
摘要:
Two supports (24) are formed on one side surface of a first housing (20) at positions symmetrical to a center of a connection area with a second housing (40) in a lengthwise direction (L). The lever (60) is selectively mounted in a first mode on one of the two supports (24) and rotated toward one side or in a second mode on the other support (24) and rotated toward the other side. The lever (60) has a first and second parts for exerting pushing forces on the first housing (20) in a direction to proceed with a connecting operation of the housings (20, 40) as the lever (60) is rotated. The first part is a cam groove (68) engageable with a follower pin (43) of the second housing (40) and the second part is a recessed groove (73) engageable with the support (24) not supporting the lever (60).
摘要:
An insulating film is formed on the surface of the base of a semiconductor, and a portion of the insulating film is removed to cause the surface to appear outside. The exposed surface is terminated with hydrogen, and then energy beams are applied to selectively remove the terminating hydrogen. Metal is selectively deposited on the portion terminated with left hydrogen atoms.

A magnetic field generator includes a base, a plurality of magnetic field generating cores formed on the base, magnetic field generating coils respectively wound around the plurality of magnetic field generating cores, a magnetic material member being disposed between adjacent twos of the plurality of magnetic field generating cores, and a drive device for driving the magnetic field generating coils. Also, a magneto-optical recording apparatus includes an optical head for irradiating a light beam to a magneto-optical recording medium and the magnetic field generator. The magnetic field generator can set the maximum modulation frequency at a higher value while ensuring a scope of the effective vertical magnetic field sufficiently and efficiently, to thereby permit multi-recording.
摘要:
A multi-track magnetic head having at least three conversion elements deposited on a common substrate includes a medium sliding face which is formed in a curved shape. The positions of at least two of the three conversion elements are shifted from each other perpendicularly to the alignment direction of the conversion elements in conformity to the curvature of the medium sliding face.
摘要:
A thin-film magnetic head having a magnetic core formed by a thin-film deposition technique on a substrate formed of crystallized glass which comprises of a mass of microcrystalline aggregation particles having an average particle size of 1 to 10 .mu.m and each comprising of an aggregation of microcrystalline grains having an average grain size of about 0.5 .mu.m or smaller. This structure enables an improvement in the abrasion resistance of the head and, hence, an improvement in the recording/reproduction characteristics while maintaining the desired workability of the substrate, thereby improving the head in producibility and reliability.
