摘要:
This invention aims to provide a communication device, installation structure for the communication device, a method of manufacturing the communication device, and a method of communication with the communication device in which the communication device is able to exceedingly restain a conductive material from attenuating magnetic flux and to expand communication distance even when the communication device is attached to a conductive member e.g., metal, in a closely contacting manner.This invention has a sheet-like amorphous magnetic material being arranged in a manner extending from a magnetic flux generating portion of a concentric disk-shaped antenna coil of an RFID tag serving as the communication device to an outer area of the antenna coil.

An engine suspension device for a motorcycle can be increased in design flexibility and weight. An engine suspension device for a motorcycle has a suspension link provided between a body frame and an engine for pivotably supporting the engine. The suspension link includes a link body. Two pairs of right and left cylindrical members are provided at opposite ends of the link body and are connected to the body frame and the engine, respectively. The pairs of right and left cylindrical members are spaced apart from each other in the lateral direction of the motorcycle. The suspension link further includes a right connecting member for connecting the right cylindrical members and a left connecting member for connecting the left connecting members. The right and left connecting members are connected to each other by the link body.

摘要:
An inspection head is used for an inspecting apparatus that inspects whether there is an abnormal projection on a disk surface having a first lubrication layer, and floats over the disk surface. The inspection head includes a floating surface covered with a second lubrication layer that is repellent to the first lubrication layer.
摘要:
A method for moving magnetic heads in a magnetic recording/reproducing apparatus, which comprises the steps of writing high-frequency signals in the magnetic recording/reproducing tracks; and then, either (i) conducting DC erasing or AC erasing to inspect extra pulse signals reproduced from the erased tracks, or (ii) inspecting concurrently occurring signals of missing pulse and spike pulse, which are reproduced from the written signals, whereby minute protrusions on a surface of the tracks were detected. Reading and writing of information are conducted while the magnetic heads are moved in a manner controlled so that reading and writing of information in specific tracks having defects is avoided. This method enhances reliability and life of the magnetic recording/reproducing apparatus.

摘要:
In a catalyst element for purifying exhaust gases having a metallic carrier and a catalyst carrying layer, an undercoat layer is formed by coating the surface of the carrier with a heat resistant inorganic oxide which is superior in adhesion to a metal. The catalyst carrying layer is then formed by carrying platinum (Pt) and rhodium (Rh) on an alumina layer. The catalyst carrier layer can thus be adhered in a close and better contact with the carrier via the undercoat layer. Even when the carrier is subjected to thermal expansion and vibrations, the amount of peeling of the platinum and rhodium off (or away from) the carrier can be minimized. Consequently, the decrease in the purifying characteristics can be minimized.
