Abstract:
An electronic watermark embedding apparatus for embedding watermark information as digital information into a document image includes a background eliminating unit that determines whether pixels on an input image are pixels composing a background image and eliminates the pixels determined as the pixels composing the background image from the input image, and a watermark embedding unit that embeds a watermark into a background eliminated image from which the background is eliminated by the background eliminating unit so as to form a watermark image. A readable watermark can be embedded into a multi-valued image including a halftone/gradation portion on the background of the input image.
Abstract:
In a wire electrical discharge machining apparatus, an upper main-discharge power supply is connected between an upper conducting terminal and a workpiece using an upper main-feeder line capable of configuring outward and homeward paths, and a lower main-discharge power supply is connected between a lower conducting terminal and the workpiece using a lower main-feeder line capable of configuring outward and homeward paths. Moreover, a sub-discharge power supply is connected between the upper conducting terminal and the workpiece and between the lower conducting terminal and the workpiece using an upper and a lower sub-feeder lines that have higher impedances than the impedances of the upper and the lower main-feeder lines and can configure outward and homeward paths.

Abstract:
This invention is to improve data retention properties of a nonvolatile memory cell having an ONO film. A first cavity is disposed, in a position between the nitride film serving as a charge storage film and a memory gate and below an end portion of the memory gate, adjacent to the upper oxide film. A second cavity is disposed, in a position between the nitride film and a substrate and below an end portion of the memory gate, adjacent to the bottom oxide film. These cavities are closed with sidewall spacers formed over the substrate along the sidewalls of the memory gate.

Pressing an electronic device (2) to be tested to contact terminals (132a and 132b) while bringing a heater (112) having equal or close temperature change characteristics to those of the electronic device to be tested by a test pattern, transmitting a test pattern to the electronic device to be tested in this state, and controlling a power consumption of a heater so that total power of a power consumption of the electronic device to be tested by the test pattern and a power consumption of the heater becomes a constant value.
Abstract:
A transfer roller lies opposite to a supporting roller across an image carrying belt and abuts against the outer surface of the image carrying belt to form a transfer nip. A driving force transmission unit transmits driving force from a driving source to a driving roller. A drive control unit performs drive control of the driving source. A feedforward control unit performs feedforward control on the driving source via the drive control unit. An entry detecting unit detects entry of a sheet in the transfer nip. The feedforward control unit considers an entry detection signal output by the entry sensor as a trigger for performing feedforward control after a predetermined time.
Abstract:
A discharge-generation control unit applies at least a preliminary-discharge voltage pulse and a main-discharge voltage pulse between a wire electrode and a work. A discharge-position determining unit determines a discharge position from results of measurement by a plurality of current measuring units. A machining-energy adjusting unit adjusts machining energy generated by the main-discharge voltage pulse based on a discharge position determined before applying the main-discharge voltage pulse, and reflects a result of the adjustment on the generation of an electric discharge by feeding the result to the discharge-generation control unit.

A wire electric discharge machine includes a wire electrode; a machining power supply that supplies a machining current to between the wire electrode and a workpiece; a first power feed contact and a second power feed contact that respectively feed power to the wire electrode; a first machining-current loop that lets a first machining current to flow from the first power feed contact toward the workpiece; a second machining-current loop that lets a second machining current to flow from the second power feed contact toward the workpiece; an impedance switching circuit that is provided in at least any one of the first machining-current loop and the second machining-current loop; and a control unit that controls a flow ratio of the first machining current and the second machining current by changing an impedance of the impedance switching circuit.
Abstract:
An encoding unit (44) individually encodes display image-forming image data, i.e., image data from an image input unit (2), decoded data from a decoding unit (46), and graphics image data from a graphics-generating unit (47). A storing unit (45) stores the individually encoded image data. As a result, when a user intends to reuse, more specifically, replay, edit, or transmit the stored display image, the user can selectively decode required image elements, thereby reusing the selectively decoded image elements. This feature provides improved user-friendliness.
