摘要:
Remote data entry is performed in such a manner that a plurality of entry items and a plurality of data items are caused to collectively enter within one communication and the check sum is calculated simultaneously with the data entry so that abnormality of the data is easily detected even if the contents of the entry data are changed due to the abnormality occurring in a facsimile apparatus. Data is collectively stored in a receiving buffer and a great quantity of data is caused to remote enter if the capacity of the buffer permits. After all remote data entries have been completed, the check sums of all entry memory regions are performed so that the memory capacity of the program code of the check sum is saved.

In a method for gathering a ring shaped wire rod, particularly a wire rod made of steel, the wire rod is continuously conveyed and gathered in the form of a coil by means of a gathering apparatus including a gathering tub and a coil plate. In accordance with the present invention, the lowering speed of the coil plate is controlled in such a manner that piling position of said rings is always within a predetermined range. In addition, the ring shaped wire rod is dropped, while imparting a movement having a horizontal component to the ring shaped wire rod so as to increase the filling ratio over that of the prior art. The coils gathered in the present invention are more compact than in the prior art.

The present invention provides a powder for a magnetic member being excellent in moldability and difficult to oxidize, a powder compact produced from the powder, and a magnetic member suitable for a raw material of a magnetic member such as a rare earth magnet. A powder for a magnetic member includes magnetic particles 1 which constitute the powder for a magnetic member and each of which is composed of less than 40% by volume of a hydrogen compound 3 of a rare earth element, and the balance composed of an iron-containing material 2 which contains iron and an iron-boron alloy containing iron and boron. The hydrogen compound 3 of a rare earth element is dispersed in a phase of the iron-containing material 2. An antioxidant layer 4 having a low-oxygen permeability coefficient is provided on the surface of each of the magnetic particles 1.

A connector includes: a card edge connector; a first cable drawn out from the card edge connector in a first direction; a first terminal disposed in the card edge connector and connected to the first cable; a receptacle into and from which the card edge connector is inserted and extracted; a second cable drawn out from the receptacle in a second direction; and a second terminal disposed in the receptacle and connected to the second cable. Insertion/extraction directions of the card edge connector are substantially perpendicular to at least one of the first direction and the second direction. The card edge connector includes a first end face which is substantially parallel to the insertion/extraction directions, and the receptacle includes a first wall face which is substantially parallel to the insertion/extraction directions. In a state where the card edge connector and the receptacle are coupled to each other, the first end face and the first wall face are in contact with each other.

Metal nanoink (100) for bonding an electrode of a semiconductor die and an electrode of a substrate and/or bonding an electrode of a semiconductor die and an electrode of another semiconductor die by sintering under pressure is produced by injecting oxygen into an organic solvent (105) in the form of oxygen nanobubbles (125) or oxygen bubbles (121) either before or after metal nanoparticles (101) whose surfaces are coated with a dispersant (102) are mixed into the organic solvent (105). Bumps are formed on the electrode of the semiconductor die and the electrode of the substrate by ejecting microdroplets of the metal nanoink (100) onto the electrodes, the semiconductor die is turned upside down and overlapped in alignment over the substrate, and then, the metal nanoparticles of the bumps are sintered under pressure by pressing and heating the bumps between the electrodes. As a result, generation of voids during sintering under pressure is minimized.

Disclosed is an Internet FAX apparatus which, after receiving an Internet address from a certain destination, can communicate with the same destination in later transmission or during communication by connecting to a LAN and switching to an Internet FAX mode requiring no communication charge. An Internet facsimile apparatus on the receiving side transmits its Internet facsimile function and Internet address on an NSF signal in a standard protocol of G3 facsimile transmission and/or transmits its telephone number, Internet facsimile function, and Internet address on TSI and NSS signals in the standard protocol of G3 facsimile communication. The Internet facsimile apparatus registers an Internet facsimile function and Internet address of a partner apparatus as destination data. The Internet facsimile apparatus communicates with the partner apparatus by using the Internet address in the destination data in later transmission or by disconnecting ordinary facsimile mode communication and switching to the Internet FAX mode.
摘要:
A bonding apparatus including a capillary 40 having a high-frequency coil 50 on its tip end portion and allowing a bonding wire 2 to pass therethrough, a position changing unit for changing the position of the tip of the bonding wire, a gas supply unit for supplying gas into the capillary, and a high-frequency power supply unit for supplying high-frequency power to the high-frequency coil. When the bonding wire is outside a plasma region 52 in the capillary, a microplasma generated in the plasma region is ejected out of the capillary and removes foreign matter or contaminants on the surface of a bonding subject. When the bonding wire is inside the plasma region, the material of the bonding wire is turned into fine particles, and a microplasma 303 containing sputtered fine particles is ejected from the capillary, allowing the material the same as the bonding wire to be deposited on the bonding subject.

A tip end portion and an outer surface of a capillary (or of a wedge tool) used in, for instance, a wire bonding apparatus and method, being covered by a diamond layer with a heating element attached to the outer surface thereof. The inside of the capillary is formed by alumina ceramics, having a tapered hole. The tip end of the capillary is formed by the diamond layer, and a face portion and an inner chamfer portion are formed at the tip end to make a wire heating portion. Heat is transferred from the heating element to the wire heating portion through a heat supply path formed by the diamond layer, and a bonding surface formed by a wire and a pad is heated.
