According to one embodiment, an electroforming master comprises a patterns of protrusions and recesses formed on one major surface of an Si substrate having two major surfaces, corresponding to information for positioning of a read/write head (a preamble, address, and burst), recording tracks or recording bits. Impurity ions are doped in the surface of this patterns of protrusions and recesses. The impurity ion concentration distribution in the film thickness direction of the Si substrate has a peak in a portion from the patterns of protrusions and recesses surface to a depth of 40 nm in the film thickness direction. The impurity concentration of this peak is 1×1020 to 2×1021 ions/cm3.

According to one embodiment, a magnetic recording medium includes a substrate, an auxiliary layer formed on the substrate, and at least one perpendicular magnetic recording layer formed on the auxiliary layer. The perpendicular magnetic recording layer includes a magnetic dot pattern. The perpendicular magnetic recording layer is made of an alloy material containing one element selected from iron and cobalt, and one element selected from platinum and palladium. This alloy material has the L10 structure, and is (001)-oriented. The auxiliary layer includes a dot-like first region covered with the magnetic dot pattern, and a second region not covered with the magnetic dot pattern. The first region is made of one metal selected from (100)-oriented nickel and (100)-oriented iron. The second region contains an oxide of the metal used in the first region.

A side surface light emitting unit illuminates, from its side surfaces, one or more objects to be illuminated which are arranged to extend in one direction on a flat surface. The side surface light emitting unit is provided with a light guide body arranged along the side surface of the objects to be illuminated, for projecting light to the side surfaces of the objects, and an LED arranged at least on one end of the light guide body. In the side surface light emitting unit, the upper surface and the lower surface, excluding the side surfaces facing the objects, are blocked from light. The objects to be illuminated, such as key switches, can be brightly illuminated by unintermittent continuous outgoing light, along the arrangement direction of the objects from one end.

A portable terminal includes a first casing having a first wiring board, a first operation portion, and an accommodating portion opened in its peripheral surface, and a second casing configured to be accommodated in the accommodating portion through the opening and having a second wiring board and a second operation portion. A casing movement guiding/supporting mechanism is interposed between one side portion of the first casing and that of the second casing in one direction intersecting a moving locus of the second casing between a retracted position and an extended position in relation to the accommodating portion, and supports the second casing to be movable linearly between the retracted and extended positions. The second casing is selectively locked at the retracted position by a locking mechanism. A battery for supplying electricity to the wiring boards is accommodated in an accommodating chamber in at least one of the casings.

A system controller, which executes a speculative fetch from a memory before determining whether data requested for a memory fetch request is in a cache by searching tag information of the cache, includes a consumption determining unit that monitors a consumption status of a hardware resource used in the speculative fetch, and determines whether a consumption of the hardware resource exceeds a predetermined value; and a speculative-fetch issuing unit that stops issuing the speculative fetch when the consumption determining unit determines that the consumption of the hardware resource exceeds the predetermined value.

The energy conversion efficiency from light that is to be converted to converted light of a wavelength conversion device is adjusted so as always to be kept stably at a maximum. The wavelength conversion device is provided with a laser light source 10 for generating a fundamental wave light, a nonlinear optical crystal 16 into which the fundamental wave light is made to enter to generate converted light, and an optical path adjusting portion 30 for adjusting the direction of propagation of the fundamental wave light and the position of the light beam of the fundamental wave light in order to make the fundamental wave light enter the nonlinear optical crystal 16 while satisfying phase matching conditions. The optical path adjusting portion 30 is constituted so as to be provided with a first reflecting mirror 12 and a second reflecting mirror 14, and the first reflecting mirror is provided with adjustment means driven by motors M1 and M2, and the second reflecting mirror is provided with adjustment means driven by motors M3 and M4. Additionally, the wavelength conversion device is provided with a semi-transparent mirror 18 for splitting off and taking out one portion of output light 17, and a photodetector 22 for detecting this split off output light. An electrical signal 23 that is output from the photodetector 22 is input into an adjustment value calculating means 26, and in this adjustment value calculating means, the necessary adjustment values for the adjustment means in the optical path adjusting portion 30 are calculated using fuzzy inference, and this result is output to an optical path adjusting portion control device 28. The optical path adjusting portion control device 28 carries out adjustment of the optical path based upon output signals 27 from the adjustment value calculating means 26.
摘要:
An output instruction including output conditions that differ by page is instructed by the output instruction unit, the instruction data is analyzed by a data analysis unit, instruction data including instructed output conditions that differ by page is stored, the image data is image-processed by an image processing unit in accordance with the instruction data stored in the data analysis unit, to thereby create an output image, the output conditions of the printing mechanism are switched by an output control unit in accordance with the instruction data, and the output image generated at the image processing unit is printed by a printing mechanism. It is determined whether or not there are contradictions in the instruction data of the image data, resetting is prompted with respect to contradictions, and an appearance when image recording is actually effected in accordance with the instruction data is displayed.
