Novel norbornene fluoroacrylate copolymers are provided. The polymers are useful in lithographic photoresist compositions, particularly chemical amplification resists. In a preferred embodiment, the polymers are substantially transparent to deep ultraviolet (DUV) radiation, i.e., radiation of a wavelength less than 250 nm, including 157 nm, 193 nm and 248 nm radiation, and are thus useful in DUV lithographic photoresist compositions. A process for using the composition to generate resist images on a substrate is also provided, i.e., in the manufacture of integrated circuits or the like.

A common electrode and an individual electrode are provided in plural pairs on a first transparent substrate, and recesses are formed in a second substrate in positions corresponding to the pairs of electrodes to define discharge cells of display cells. The display cells of a display panel can be individually driven on the cell-by-cell basis and the planar panel has a reduced thickness. A voltage pulse is applied to the individual electrode to reverse the polarity of wall charges accumulated on a dielectric layer, and a voltage pulse is then applied to the common electrode so that an electric field of the wall charges caused upon the reversal of the polarity is additionally applied. Thereby provided are a planar display panel which can set a large control margin in the display operation, ensure stable display, and present gradation display with high reliability and quality.

An electron emission light-emitting device comprises an electron emission device and a fluorescent material layer formed on the thin-film metal. The electron emission device comprises an electron-supply layer made of semiconductor formed on an ohmic electrode; an insulator layer formed on the electron-supply layer; and a thin-film metal electrode formed on the insulator layer. The electron emission light-emitting device emits light when an electric field is applied between the electron-supply layer and the thin-film metal.

A color cathode ray tube includes a generally rectangular shadow mask having a curved apertured portion having a multiplicity of electron-transmissive apertures, a curved imperforate portion surrounding and integral with the apertured portion and a skirt portion bent back from a periphery of the curved imperforate portion, and a generally rectangular support frame for suspending the shadow mask by spot welding the skirt portion thereto, within a panel portion of the color cathode ray tube. The skirt portion is provided with a plurality of embossments and is fitted inside the support frame. The embossments protrude inwardly and extend in a direction of a height of the skirt portion. A distance between a bottom of each of the plurality of embossments and a border of the curved apertured portion is at least 4.5 mm.

A recording medium carrier system of an image forming apparatus is constituted by independent units as a paper supply cassette, a paper feed unit, a transfer unit, a fixing unit, and a paper ejecting unit. An intermediate transfer unit in the transfer unit is provided with an intermediate transfer belt to which a toner image formed on a photoconductive drum is primarily transferred at a primary transfer position and which secondarily transfers the toner image on a recording medium at a secondary transfer position, and a driving roller for circulating the intermediate transfer belt. The primary transfer position is arranged close to the driving roller.

A common electrode and an individual electrode are provided in plural pairs on a first transparent substrate, and recesses are formed in a second substrate in positions corresponding to the pairs of electrodes to define discharge cells of display cells. The display cells of a display panel can be individually driven on the cell-by-cell basis and the planar panel has a reduced thickness. A driving circuit for changing luminance in accordance with the number of pulses applied to the individual electrode within a unit time to make gradation display is provided, and gradation control is achieved by performing switching control for each of the individual electrodes provided independently of one another in one-to-one relation to the display cells. A voltage pulse is applied to the individual electrode to reverse the polarity of wall charges accumulated on a dielectric layer, and a voltage pulse is then applied to the common electrode so that an electric field of the wall charges caused upon the reversal of the polarity is additionally applied. Thereby provided are a planar display panel which can set a large control margin in the display operation, ensure stable display, and present gradation display with high reliability and quality, as well as a manufacturing method, a controller, and a driving method for the planar display panel.

An optical print head, which records an image in accordance with image data on a photosensitive recording medium by exposure/unexposure to light, comprises a light source for emitting light, a light source conversion unit for converting the light into linear light in substantially uniform light quantity in the same direction as a main scanning direction and emitting the linear light. A liquid crystal shutter array selectively passes or shuts out the linear light falling on the recording medium based on the image data.

A color cathode ray tube including a generally rectangular shadow mask with at least a long side, a short side and a corner, and having a curved apertured portion with a multiplicity of electron-transmissive apertures, a curved imperforate portion surrounding and integral with the apertured portion and a skirt portion bent back from a periphery of the curved imperforate portion. A generally rectangular support frame is provided for suspending the shadow mask by spot welding the skirt portion thereto within a panel portion of the color cathode ray tube. The skirt portion is provided with a plurality of slits extending in a direction of a height of the skirt portion and a plurality of embossments extending in the direction of the height of the skirt portion in one of a long side and a short side of the skirt portion. The plurality of slits and the plurality of embossments are juxtaposed around a circumference of the skirt portion with a majority of the plurality of slits in the one of the long side and the short side of the skirt portion being unbridged slits or with the plurality of slits extending a distance no greater than 70% of the height of the skirt portion from a rear end of the skirt portion on an opposite side thereof from the panel portion.

A method of forming a groove having a desired cross section easily and rapidly, by making laser beam scan in the longitudinal direction of the groove. In the method, a laser beam 11 is irradiated to a work 15 to form a groove 16. When the longitudinal and the width direction of the groove is the x-axis and the y-axis, respectively, an intensity distribution of the laser beam in an irradiated region Q on the work is expressed by f(x, y). An integral of f(x, y) with respect to x, i.e., g(y), is proportional to a depth distribution of the groove 16, d(y), and the intensity distribution f(x, y) is formed by passing the laser beam 11 through a mask pattern 12a which has an appropriate transmission factor distribution. The groove 16 is formed by moving the region Q in the x-axis direction. The cross section of the groove 16 is determined by the mask pattern 12a. And the groove 16, having a desired cross section, is obtained in one scanning in the x-axis direction.

A trick action type clock, wherein a dial plate which is arranged in front of ornaments is made of left and right side dial plates mating along a line passing through a center of rotation of the hands. A planetary gear mechanism actuates the left and right side dial plates so as to make them rotate and revolve around the center of rotation of the hands to produce an opening and closing motion. Therefore, the dial plate made of the two mating parts performs an opening and closing motion which produces a strong impression due to the surprising dynamic change.
