摘要:
A communication apparatus performs communication of data using assigned time slots within a frame. In a case where data cannot be transmitted in a transmission time slot that has been assigned in order to transmit data, a time slot later than this transmission time slot is reserved as a time slot used to transmit the data, this later time slot being reserved within the frame having the transmission time slot in which the data cannot be transmitted.

The present invention provides a method of forming a fine pattern by the post-firing method. The production method of a metallized ceramic substrate comprises: a first step of forming an organic base layer on a ceramic substrate; a second step of forming a metal paste layer on the organic base layer to produce a metallized ceramic substrate precursor; and a third step of firing the metallized ceramic substrate precursor, wherein the organic base layer is a layer which absorbs a solvent in the metal paste layer and thermally decomposes at a temperature of firing the metal paste layer.

The present invention has as an object to render a photochromic coating layer free from air bubbles and obtain a uniform layer without film thickness unevenness in the coating layer. In the prevent invention, entrained air in a coating fluid stored in a vessel of a coating unit comprising the vessel, a check valve for preventing back-flow of the coating fluid connected to the vessel, and optionally an ejection nozzle connected to the check valve; air existing inside of the check valve; and optionally air existing inside of the ejection nozzle are removed by plugging an outlet of the coating fluid existing downstream of the check valve and then rotating the coating unit on an axis of the vessel and orbiting the coating unit on a revolution axis simultaneously.

An alpha-turn coil includes: a plurality of coil main bodies made by winding a wire rod having a desired diameter; and lead wire having a start part and a stop part formed integrally with outer peripheries of the coil main bodies, and connecting the coil main bodies to each other. The stop part of the lead wire of a forward coil main body is extended to the start part of the lead wire of a backward coil main body, and the lead wire is extended to compose the coil main body.
摘要:
A feature value corresponding to each of a plurality of pixel values is calculated for an image. A pixel value is selected for which a minimum distance is obtained in a feature space between the calculated feature value and a feature value of a template. The selected pixel value is employed as a threshold value at which a subject area and a background area in the image are separated from each other.
摘要:
Processing for improving the contrast of an image of interest is executed by an image processing circuit in an X-ray photography apparatus. The image is decomposed into coefficient values of a plurality of frequency bands by a frequency-component decomposition circuit to obtain coefficients of each and every frequency band. A coefficient conversion circuit converts coefficient values with regard to at least one frequency band of the plurality of frequency bands in such a manner that a frequency distribution of coefficient values of every frequency band will become a prescribed frequency distribution. A restoration circuit generates an image using the coefficient values obtained by the conversion performed by the coefficient conversion circuit.
