摘要:
The present invention provides a radio frequency identification (RFID) tag which exchanges information with an external device in a noncontact manner, in which a paste is used as a material for an antenna, and which is designed to prevent sinking of bumps. A stopper for limiting sinking of bumps of a circuit chip caused by a pressing force when the circuit chip is connected to an antenna is provided on the circuit chip or a base at a position adjacent to the bumps.

An IC chip mounting method which mounts two or more IC chips on a base, includes: preparing a wafer by mounting a tape on a face thereof, which is the reverse of the wafer having a mounting surface to be attached to the base, and by dividing the wafer into IC chips by dicing while leaving the tape; positioning the wafer to face the base in such a direction that the mounting surface to be attached to the base faces the base; sequentially pressing the IC chips on the wafer against the base and temporarily fixing the IC chips while the base is being fed in a prescribed one-dimensional direction along the wafer and while the wafer is being moved two-dimensionally along the base; and fixing the IC chips temporarily fixed on the base on the base by heating and pressurizing in a batch manner.

A magnetic field detector includes: a magnet; a magnetic resistance element used for detection having a layer structure containing a ferromagnetic layer, the resistance being changed when a direction of magnetization of the ferromagnetic layer is changed; and a magnetic resistance element used for reference having the substantially same layer structure as that of the magnetic resistance element used for detection, wherein a magnetic field, the magnetic intensity of which is higher than the saturation magnetic field, is impressed by the magnet in the direction which is felt by the ferromagnetic layer of the magnetic resistance element used for reference.

The magnetic head tester of the present invention drives a medium for rotation to float a slider from the medium so as to test a magnetic head for its characteristics, and the tester includes a holder removably holding the slider opposed to the surface of the medium, and suspension means provided in the holder which has the same function as a suspension supporting the slider in a real apparatus. With this tester, tests can be executed by exchanging the slider alone, and it is unnecessary to discard the suspension even when the magnetic head is judged to be defective, thus the loss of production costs for the suspension and processing costs for assembling the slider in the suspension can be avoided.

A coating machine 3 serving as a rotary atomizer comprises a hollow unrotary paint nozzle shaft 5 provided in the center of a motor shaft 10 serving as its rotary shaft. The paint nozzle shaft 5 is provided at a tip thereof with a gun-spray paint nozzle 5g and a gun-spray air nozzle 5f on the outside of the gun-spray paint nozzle 5g in the diametrical direction, and a needle shaft 21 is disposed in a paint passage 5b in the paint nozzle shaft 5 so as to serve as a valve mechanism for selectively supplying paint to either a bell cup 4 or the gun-spray paint nozzle 5g.

A resin block has a treating solution channel extending between and opening at front and back surfaces thereof. Heat conductive members are face-bonded to the front and back surfaces of the resin block, respectively, for closing the channel. Consequently, no air is present between the resin block and heat conduction members, thereby improving the efficiency of heat exchange. A nozzle of simple construction is realized only by face-bonding the two heat conductive members to the open front and rear surfaces of the resin block. Temperature control plates hold the heat conductive m embers along with the resin block to effect a temperature control, whereby the temperature of a treating solution in the treating solution channel is controlled effectively through the heat conductive members. The treating solution adjusted to a desired temperature is delivered from a discharge opening to a substrate for performing substrate treatment with high accuracy.

A solid-state imaging device has a substrate in which are formed a pixel array portion having a plurality of pixels, and a peripheral circuitry portion. The device is characterized in that a first multilevel metallization structure is formed over the peripheral circuitry portion, and a second multilevel metallization structure thinner than the first multilevel metallization structure is formed over the pixel array portion.

A remote controller which is associated with a player is configured by a first remote controller and a second remote controller. The first remote controller 100 is a simplified remote controller comprising only operating keys relating to basic functions, such as a power source key 5, a play key 6, a stop key 7, a forward key 8, and a reverse key 9. Because of the small kinds of keys, even a child can easily operate the player. By contrast, the second remote controller is an ordinary remote controller which comprises various keys in addition to the operating keys 5 to 9 of the remote controller 100, thereby enabling complex operations to be performed.

A method of making a casting having a cast portion and a cap nut includes forming a hole with a stepped shape in the cap nut to have a large-diameter hole on an opening side and a threaded small-diameter hole on a bottom side, inserting a fixing member into the large-diameter hole, supporting the fixing member in a sand mold, pouring a casting material into the sand mold so that the cap nut is enveloped in the cast portion and that a first surface of the cap nut adjacent to the hole is exposed outside without being covered with a second surface of the cast portion, and removing the fixing member from the cap nut after the casting is taken out of the sand mold.
