An IC tag can be mounted without deteriorating appearance of a container, breakage or the like of the IC tag can be prevented and excellent wireless communication between a reader/writer becomes possible by eliminating influence of the metal container by ensuring a long communication distance to the reader/writer by allowing excellent communication properties to be exhibited even when an existing IC chip is used and mounting an insulated and sealed IC tag on a metallic cover having a low possibility of being brought into contact with other goods and equipment and being hidden by the adjacent metallic containers. The metallic cover is provided with an IC chip (41), which has a pull-tab (33), and an IC tag (40) for the IC chip (41) mounted on the tab (33), an antenna for the IC tab (40) and a matching circuit (50) for matching impedances between the antenna and the IC chip.

An object of the present invention is to provide a novel system for supporting a vibrator having a terminal for electrical connection so that the vibrator may be miniaturized and the deviation of vibration property among vibrators mounted on the supporting systems may be prevented. The supporting system has a substrate 11 and bonding wires 9, 10 supported on the substrate 11 and to be joined with a vibrator 1. The vibrator 1 is supported with the bonding wires 9, 10 so that the vibrator 1 does not directly contact the substrate 11 and bonding wires 9, 10 are electrically connected with a terminal 6 of the vibrator 1.

Method and apparatus of controlling an image display process in which image data is input to display an image of the image data on a display. The input image data is stored in a first memory with respect to pixels, and a second memory, having at least an address space corresponding to a display region on the display in which the image of the image data is displayed, stores, in each display address, address information on an address of the first memory in which pixel data in the image data on a pixel to be displayed in the display region in accordance with the display address. The address information on the address in which the pixel data is stored is read out and the pixel data is read out from the first memory based on the address information to display the pixel.
摘要:
A vibration gyro element includes drive vibrating arms and detection vibrating arms at the opposite side, and has a first detection mode in which the drive vibrating arms flexurally vibrate oppositely to each other in an out-of-plane direction in an opposite phase to an action direction of Coriolis force and the detection vibrating arms flexurally vibrate oppositely to each other in the out-of-plane direction in an opposite phase to that of the drive vibrating arms, and a second detection mode in which the drive vibrating arms flexurally vibrate oppositely to each other in the out-of-plane direction in the same phase as the action direction of the Coriolis force and the detection vibrating arms flexurally vibrate oppositely to each other in the out-of-plane direction in the same phase as that of the drive vibrating arms.
摘要:
A bending vibration piece has a pair of drive vibration arms and a pair of detection vibration arms in an opposite direction thereto which are connected to a supporting part. The supporting part has recessed portions formed on both lateral parts in a direction of width, and a through-hole formed substantially at the center in a plane part of the supporting part and more toward the drive vibration arms than the recessed portions are. On a surface of the supporting part, drive electrode pads are arranged toward the drive vibration arms and detection electrode pads are arranged toward the detection vibration arms, with these electrode pads being separated from each other in a longitudinal direction by the recessed portions on both lateral part of the supporting part and the through-hole in the plane part.
