A process for producing a periodic structure comprises the steps of preparing a working object, the property of which changes in view of a photoreaction caused by an exciting energy, generating a light having a photonic energy of intensity of one fraction of natural number divisions of the exciting energy by each of the light sources of light-source groups arranged regularly in a two-dimensional arrangement, and concentrating the light emitted from the light source group at each of the light-concentrating points arranged at regular intervals in the working object to cause a photoreaction at and around the light-concentrating point to form a periodic structure comprised of regions each of which has a changed property in the working object.

According to one embodiment, a disk drive has a magnetic disk and a magnetic head having a spin-torque oscillator. The disk drive further has a head amplifier IC configured to supply a write signal and a drive signal to the magnetic head. The write signal corresponds to write data. The drive signal is supplied to generate a high-frequency magnetic field. The head amplifier IC continuously supplies a drive signal of normal level to the spin-torque oscillator, and supplies a drive signal of high level higher than the normal level, only for a prescribed time after the polarity inversion of the write signal.

The invention provides a block polymer capable of being used as a molecular wire facilitating injection of carriers between itself and an electrode, and a device in which electrodes are bridged by one molecule. The block polymer has a main chain composed of polyacetylene having a spiral structure, and includes a coating insulating block and a conductive block. The coating insulating block has a polyacetylene unit structure having alkyl chains at its side chains through functional groups, the alkyl chains being arranged in a direction parallel to the major axis of the main chain. The conductive block has a polyacetylene unit structure having hydrogen atoms at its side chains through functional groups, the hydrogen atoms being arranged in a direction parallel to the major axis of the main chain. The device has the above-mentioned block polymer, and two or more electrodes.

A compound represented by formula (I) wherein the symbols in the formula are the same meanings as those in specification, salts thereof, solvates thereof, or prodrugs thereof binds to DP receptor and shows antagonistic activity for DP receptor. Thus, it is useful for prevention and/or treatment of diseases such as allergic disease (e.g., allergic rhinitis, allergic conjunctivitis, atopic dermatitis, bronchial asthma and food allergy), systemic mastocytosis, disorders accompanied by systemic mast cell activation, anaphylaxis shock, bronchoconstriction, urticaria, eczema, diseases accompanied by itch (e.g., atopic dermatitis and urticaria), diseases (e.g., cataract, retinal detachment, inflammation, infection and sleeping disorders) which is generated secondarily as a result of behavior accompanied by itch (e.g., scratching and beating), inflammation, chronic obstructive pulmonary diseases, ischemic reperfusion injury, cerebrovascular accident, chronic rheumatoid arthritis, pleurisy, ulcerative colitis, etc. Since it specifically binds to DP receptor and binds weakly to other prostaglandins receptors, they can be pharmaceuticals having little side effect.

摘要:
In a disk drive, a disk medium includes servo areas on which servo data is recorded and data areas on which data is recorded. In each of data tracks in, e.g., an outer radius of the disk medium, the inclination θ2 of the servo data recorded on the servo areas is smaller than the inclination θ1 of the data recorded on the data areas.

A device for detecting a target substance in a fluid is provided. This device comprises a periodic structure having a vacant portion for passing the fluid containing the target substance and a solid portion arranged regularly and capable of transmitting an electromagnetic wave, an electro-magnetic wave-projecting means for projecting the electromagnetic wave to the periodic structure, and a detecting means for measuring the magnetic wave emitted from the periodic structure to detect a change in periodic distribution of a refractive index. This sensor is highly sensitive in a small size.
摘要:
There is disclosed a servo writing method in which servo data is recorded by a perpendicular magnetic recording system. In the servo writing method, at the time of perpendicular magnetic recording of the servo data on a disk, a servo writing operation is executed including an offset process set based on the hard-easy transition shift (HETS) phenomenon.
摘要:
An information recording/reproduction is performed as follows on a recording medium using a probe. A distance between the probe and a recording layer of the recording medium is controlled, and relative movement of the probe and the medium is effected so that the probe scans a surface of the recording layer. Recording bits corresponding to information is recorded or erased on the recording layer under a predetermined recording/erasing condition. The information is reproduced from the recording bits produced on the recording layer upon detection of a physical quantity such as a tunneling current, an electric field radiation current and the like generated between the probe and the recording layer. A characteristic/state such as an electrical characteristic, a surface state and the like of the recording layer is detected. The recording/erasing condition is corrected on the basis of the detected characteristic/state of the recording layer.
