摘要:
The track width of a magnetic head is specified by the interval between a pair of grooves in the slider surface that are formed by a projection ion beam. Specifically, the grooves are processed by projecting a mask having the pattern of the pair of grooves with a projection ion beam with reduction to a magnification of 1/10, for example. Although the peripheral strain of the pattern thus formed is large and the current distortion is not uniform when the projection ion beam batch irradiation area is limited, the increase in depth of the grooves formed at the periphery of the grooves does not affect the track narrowing process at the center portion of the projection ion beam since the strain thereof is negligibly small. As a result, a narrow track width is processed with high precision.

A processing method and a processing apparatus realizing the method use a focused ion beam generator. The apparatus includes a plasma or liquid metal ion source producing ions not influencing electric characteristics of a sample, an ion beam generator for extracting ions from the ion source into an ion beam, an ion beam focusing device for focusing the ion beam, an irradiator for irradiating the focused ion beam onto the sample, and a sample chamber in which the sample to be irradiated for processing is installed. The focused ion beam is irradiated onto a sample such as a silicon wafer or device to conduct on a particular position of the sample a fine machining work, a fine layer accumulation, and an analysis.

A weak-link Josephson junction is of the type employing a thin film of an oxide superconductor, in which a crystal grain boundary produced reflecting an artificial crystal defect is utilized as the weak-link junction. The crystal grain boundary is formed concretely by a method in which atoms of different species are deposited on the predetermined part of the surface of a substrate, the predetermined part of the surface of a substrate is disturbed, or parts of different crystal face orientations are formed at the surface of a substrate, whereupon the superconducting thin film is epitaxially grown on the substrate, or by a method in which the predetermined part of the superconducting thin film, epitaxially grown on a substrate, is diffused with atoms of different species hampering a superconductivity, or the predetermined part of the superconducting thin film is disturbed, whereupon the superconducting thin film is annealed.

A partition is formed by the process including a step for providing a sheet-like partition material that covers a display area and outside thereof on the surface of the substrate, a step for providing a mask for patterning that covers the display area and the outside thereof, so that a pattern of the portion arranged outside of the display area of the mask is a grid-like pattern, a step for patterning the partition material covered partially with the mask by a sandblasting process, and a step for baking the partition material after the patterning.

A functional sheet is brought into intimate contact with a front surface of a plasma display panel, and the functional sheet has a structure in which heat diffusion is superior to heat insulation between the plasma display panel and outside air. In addition, a display device includes a controller for controlling a drive voltage pulse train so that power consumption in a unit area in a light emission region within the screen is limited under a set value when one image is displayed.

A technology capable of stably maintaining the address discharge characteristics even in a long-term drive of a PDP is provided. A PDP has a structure where projecting portions are provided to a display electrode pair used for surface discharge so as to extend toward a reverse slit side in a cell region. Address discharge is performed between a scan electrode having the projecting portion and an address electrode. Since surface discharge in the display electrode pair and address discharge using the projecting portion are positionally separated from each other in this structure, address discharge characteristics are stabilized even if a protective layer is degraded due to the surface discharge.

A front sheet that is a layered film glued on a front face of a display panel includes a front portion made of plural layers having the same plane size and different functions and a rear portion having a plane size smaller than the front portion and larger than the screen, and the rear portion is put on the front face of the display panel.
摘要:
A transmission-type PDP capable of dealing with a moiré pattern which occurs on a display surface of a panel is provided. This PDP comprises: a rear unit having a pair of lateral display electrodes; a front unit having a longitudinal address electrode and including a display surface; and a barrier rib having transmittance and a phosphor layer. An electric potential of the address electrode is held constant in a display period. In this manner, a layer of the longitudinally striped address electrodes (first shielding layer) achieves an effect of shielding electromagnetic wave. Further, a layer of a laterally-striped electrode pattern (second shielding layer) may be arranged on a front surface of the panel. Superposing the above two shielding layers prevents the occurrence of a moiré pattern.
