A system and process for capturing and rendering ink is described. An ink canvas object may contain none, one, or more objects or elements and may specify the z-order of the objects or elements. The ink canvas object may host a variety of objects or elements and, therefore, provide ink functionality to the objects or elements, even though they themselves may not have ink functionality.

The present invention provides a method for manufacturing an electronic component of laminated ceramics such as a laminated ceramic capacitor in which, when a ceramic paste is applied on a ceramic green sheet in order to substantially eliminate steps caused by the thickness of a film of inner circuit elements such as an inner electrode, the ceramic paste is prevented from generating a gap between the paste and the film of inner circuit elements, or the thickness of the ceramic paste is prevented from being increased, by allowing the paste to overflow the film of inner circuit elements, even when the application position has been a little shifted, wherein an inclined face is formed at the periphery of an inner electrode that serves as the film of inner circuit elements, the ceramic paste being applied so as to overlap the periphery of the inner electrode, and wherein the used ceramic paste contains about 40% by weight to 85% by weight of solvents in order to facilitate smooth leveling of the applied ceramic paste.

A non-volatile semiconductor memory device is provided with a circuit that protects a tunnel oxide film from the charging phenomenon. This circuit comprises a first junction diode including an N+-type diffusion layer and a P-type well, and a second junction diode including a P-type well and an N-type well. When a voltage applied to the control gate is greater than all of a write voltage, a read voltage, and an erasure voltage that would be applied to the control gate, a current is guided through that circuit.

摘要:
A micro-abrading method wherein an abrading section undergoes a micromotion in the XY-direction parallel with the surface of a workpiece according to the operation of an actuator comprising piezoelectric elements, and an abrading material is held between the abrading section positioned at the lower end of an abrading tool and the workpiece. The phase difference between the X-direction motion and the Y-direction motion is cyclically changed while the abrading section is undergoing the micromotion, and the surface of the workpiece is entirely and uniformly abraded even though a large area is abraded.
