摘要： A DRAM having a data preset function is disclosed. A memory cell includes connectors which are formed of contact holes or through holes and which can be selectively formed in order to program preset data. For example, when preset data "0" is programmed, connectors are formed, and connector 17 is not formed. When a data precharge signal of a high level is applied, a transistor is turned on and as a result, a data storage capacitor is discharged. In other words, predetermined data is written into capacitor. Thus, the DRAM having the data preset function is provided.

摘要： The present invention provides a PDP especially having a high definition or super high definition cell structure and realizing excellent image display performance by obtaining light-emitting efficiency as favorable as or more favorable than conventional PDPs while suppressing discharge voltage rise.Therefore, strip-shaped display electrodes 4 and 5 of a PDP 1 are respectively composed of a combination of a transparent electrode 41 and a bus electrode 42 and a combination of a transparent electrode 51 and a bus electrode 52. An electrode gap d between electrodes 41 and 51 falls in a range of 5 μm to 60 μm. A ratio of a total surface area of the electrodes 41 and 51 to a total surface area of discharge cells falls in a range of 0.6 to 0.92. Thus, a discharge start length is larger than the electrode gap d. A product of a total pressure P of a discharge gas and the electrode gap d falls in a range of 13.33 Pa·cm to 133.3 Pa·cm. The discharge gas consists of xenon of 100%. The total pressure P of the discharge gas falls in a range of 2.0 kPa to 53.3 kPa. Thus, a start point of discharge is longer than electrode gap d.
摘要翻译：本发明提供了一种特别是具有高清晰度或超高分辨率单元结构的PDP，并且通过在抑制放电电压上升的同时获得优于常规PDP的发光效率而实现优异的图像显示性能。因此，PDP1的带状显示电极4和5分别由透明电极41和总线电极42的组合以及透明电极51和总线电极52的组合构成。电极间的电极间隙d 41和51落在5μm至60μm的范围内。电极41和51的总表面积与放电单元的总表面积的比率落在0.6至0.92的范围内。因此，放电开始长度大于电极间隙d。放电气体的总压力P与电极间隙d的乘积在13.33Pa·cm〜133.3Pa·cm的范围内。放电气体由100％的氙组成。排出气体的总压力P在2.0kPa〜53.3kPa的范围内。因此，放电的起始点比电极间隙d长。

摘要： In a method for producing a multilayer printed wiring board, first and second copper foils for surface layer are disposed on both sides of an inner wiring substrate so that each of first and second prepreg sheets provided with through-holes is sandwiched between each of the copper foils for surface layer and each face of the substrate, the through-holes being formed therethrough at desired positions corresponding to positions where the connecting pads on each face of the substrate are formed, and the resulting structure is integrally bonded by applying heat and pressure thereto. During the heat- and pressure-processing step, the through-holes within the prepreg sheets are filled with a resin fused from the prepreg sheets. After selectively removing the copper foil for surface layer within an area which matches each of the connecting pads, the resin is selectively removed by the irradiation of laser beams to form via holes and allow the connecting pads to be exposed. Next, a conductive paste is embedded in the via holes. According to the above-mentioned method, it is possible to suppress occurrence of defective in boring of the via hole for electrically connecting circuit patterns of the surface layer to circuit patterns of the inner layer and also to shorten the production term and reduce the production cost.

摘要： Disclosed is a process for preparing a multi-layer printed wiring board including the step of forming a through hole and an external layer circuit on a laminated board of double-sided or multi-layer construction. Then the laminated board is coated over the whole front and back surfaces with a paste-like heat-resistant resin, simultaneously filling the through hole with a resin. A copper foil is disposed on the whole front and back surfaces of the laminated board. Next, the arrangement is heated and pressure-molded in a vacuum. The copper foil is then removed to form an intermediate laminated board. Then, multilayer molding of at least two sets of intermediate laminated boards with a prepreg interposed therebetween is preformed via a step of heat and pressure-molding. In using the penetrated through hole as the divided via hole, there is no longer a restriction of the thickness of the respective divided via holes on the same lattice point. Thus, it has become possible to use the via holes in a higher multilayer board, dramatically improving wiring capacity over the prior art divided via holes.
