A method for manufacturing a microelectrode includes one of allocating organic molecules or forming an organic molecular layer on a first substrate, applying a release agent onto a desired pattern formed on a second substrate, attaching an electrode material to the release agent, and bonding a surface of the second substrate to which the electrode material is attached and a surface of the first substrate on which the organic molecules are allocated or the organic molecular layer is formed to transfer the electrode material to the first substrate.

In a probe apparatus that intermittently irradiates a sample with excitation light to observe the sample while subjecting a cantilever including a probe arranged to face a surface of the sample to self-excited vibration at a predetermined frequency, the sample is irradiated with the excitation light at a predetermined timing when a distance between the probe and the sample is not greater than a predetermined distance.

The fact that “with respect to a process in which the output value of a downstream air-fuel ratio sensor (sensor output value) is inverted from the minimum output value to the maximum output value during execution of an active control, the local maximum and minimum values of the secondary differential value of the sensor output value is widely affected by the size of the response delay of the downstream air-fuel ratio sensor and the size of the degree of the degradation of the three-way catalyst” is utilized. By preliminarily acquiring and memorizing, as maps, these relations obtained through an experiment, and applying the “local maximum and minimum values of the secondary differential value of the sensor output value” calculated from the transition of the sensor output value acquired during execution of the active control to the maps, the response delay (time constant) of the downstream air-fuel ratio sensor is acquired.

A second waveguide is formed near a first waveguide for guiding light to the vicinity of a main pole of a thermally assisted magnetic recording head, and a portion of light propagated through the waveguide 1 is branched to the second waveguide. The light transmitting in the second waveguide is detected by a photodetector to detect an intensity of the light propagated through the first waveguide. In the magnetic recording apparatus, an intensity of a semiconductor laser is decreased when an amount of light incident to the photodetector is large and the intensity of the semiconductor laser is increased when the amount of light incident to the photodetector is small. By constituting a feedback loop as described above, the intensity of the light propagated through the first waveguide is kept constant.

A magnetic recording head includes a main magnetic pole generating a recording magnetic field, a trailing shield, a recording coil generating a magnetic field and a high frequency oscillator. The trailing shield includes a magnetic region including a gap side end surface facing a write gap and a nonmagnetic film arranged in the vicinity of the write gap in the trailing shield, and within a plane including track width direction centers of the main magnetic pole and the high frequency oscillator and being perpendicular to a recording layer of a recording medium, a film thickness of the nonmagnetic film along a track moving direction is substantially equivalent to or more than a half of a distance from the gap side end surface to the nonmagnetic film.

An optical near-field generating efficiency of an optical near-field generating element is improved and a temperature rise of the element is suppressed. An optical near-field is generated using a conductive structure having a cross-sectional shape whose width in a direction perpendicular to a polarization direction of incident light transmitted through a waveguide gradually becomes shorter toward a vertex where an optical near-field is generated and having a shape whose width gradually, or in stages, becomes smaller in a traveling direction of the incident light toward the vertex where an optical near-field is generated. The waveguide is arranged beside the conductive structure and an optical near-field is generated via a surface plasmon generated on a lateral face of the conductive structure.

A thermally assisted magnetic recording head is formed of a slider and a magnetic head. The magnetic head includes a main pole, a reader, a coil, a near-field transducer, and a waveguide. A metal film with high thermal conductivity is formed at both sides of the near-field transducer in a width direction of the magnetic head. The use of the metal film as a radiator plate ensures to prevent the temperature of the near-field transducer from becoming locally high.
摘要:
A homeotropic alignment liquid crystal film is provided with a liquid crystalline substance containing a side chain liquid crystalline compound having an oxetanyl group, as a constituent, aligned homeotropically on an alignment substrate while being in a liquid crystal state and fixed in the homeotropic alignment by allowing the oxetanyl group to react. Thus, the homeotropic alignment liquid crystal film can be stably produced without necessitating a complicated step such as light irradiation under an inert gas atmosphere and is excellent in alignment retainability after being fixed in the homeotropic alignment and in mechanical strength.
摘要:
When a semiconductor laser is arranged outside a slider and a light is to be guided to the slider through a waveguide, the following problems will be solved: the stability of the flying slider is deteriorated due to a stress from the waveguide; and when an actuator is arranged near the flying slider, the motions of the slider are hindered by the waveguide. A waveguide for guiding a light to a light irradiating unit inside a slider, which floats over a medium and has the light irradiating unit for irradiating a light to the medium; and a waveguide for propagating a light from the light source to the waveguide inside the slider, are included. The two waveguides are not in contact with each other, and a relative portion between the two waveguides is movable.
