摘要:
A bonding apparatus (10) that bonds an electrode of a semiconductor die (12) and an electrode of a circuit board (19) using a metal nano paste includes a bump formation mechanism (20) that forms bump by injecting microdroplets of a metal nano paste on each electrode, a primary bonding mechanism (50) that carries out primary bonding to the electrodes in a non-conductive state by pressing the bump of the semiconductor die (12) against the bump of the circuit board (19), and a secondary bonding mechanism (80) that includes a pressurizing unit that pressurizes the primary bonded bump in bonding direction, and that carries out secondary bonding so that the electrodes become conductive by heating the bump up to a temperature higher than a binder removal temperature of the metal nano paste and a dispersant removal temperature of the metal nano paste, removing the binder and the dispersant, and pressurizing and sintering the metal nanoparticles in the bump. With this, it is possible to efficiently bond the electrodes with a simple and easy way while reducing a bonding load.

A soft magnetic material includes a plurality of composite magnetic particles (40) each including a metal magnetic particle (10) and an insulation coating (20) covering the surface of the metal magnetic particle (10), wherein the insulation coating (20) contains Si (silicon), and 80% or more of Si contained in the insulation coating constitutes a silsesquioxane skeleton. Therefore, it is possible to effectively decrease a hysteresis loss while suppressing an increase in eddy-current loss.

An electric cutoff circuit for preventing overheating of a load. The current shutoff circuit includes an FET connected to a motor circuit. A relay fault detection circuit is connected to the motor circuit to detect potential at the motor circuit. A CPU sends a control signal to a relay. The CPU determines whether a fault has occurred in the relay based on the control signal sent to the relay and the detection of the relay fault detection circuit. When determining that a fault has occurred in the relay, the CPU opens the FET to configure an open circuit with the motor circuit.

A start control apparatus has a steering lock mechanism, which includes a lock pin and a lock control unit. The lock pin is selectively engaged and disengaged from the steering shaft. The lock control unit controls the lock pin. The start control apparatus further includes a portable communication device, a verification control unit, which communicates with the portable communication device, a power source control unit, which control power supply, an engine control unit, which controls the engine, a lock state detecting switch, which detects an engaged state and a disengaged state of the lock pin. The lock control unit and the power source control unit monitor detection signals from the lock state detecting switch. The engine is permitted to be started on condition that the control units acknowledge that the lock bar is in the disengaged state.

A vehicle security device for improving the security level of a vehicle. The vehicle security device is connected to an engine and communicates with a portable device. A smart ECU performs a first coded communication to establish mutual authentication with the portable device. An ID code box is connected to the smart ECU, has a first code and a second code, and does not communicate with the portable device. The ID code box performs a second coded communication using the first code to establish a second mutual authentication with the smart ECU. An engine ECU performs a third coded communication using the second code to establish a third mutual authentication with the ID code box. The engine ECU enables the engine to be started when every one of the first, second, and third mutual authentications are established.

A bonding apparatus 10 including an X and Y motor parts 20 and 50, which have substantially the same construction, and a moving table 60, which can be moved in the XY plane by these motor parts. The X motor part 20 and Y motor part 50 are connected to the moving table 60 by joint mechanisms 42 and 52 that are rotatable. In the X and Y motor parts 20 and 50, the movable coils 30 of the movable elements 24 are shaft-supported by shaft-supporting mechanisms 36 so that these coils are rotatable about the Z axis, and the shaft-supporting mechanisms 36 are guided so as to be movable linearly in the X and Y axial directions respectively by a guide mechanism formed with guide rails 38 and linear guides 37.

A CI signal of a V.8 protocol is transmitted in response to the reception of a DIS signal indicating the provision of a V.8 facility, and the V.8 protocol is executed in response to the reception of an ANSam signal of V.8, and when the DIS signal indicating the provision of the V.8 facility is received without receiving the ANSam signal, the CI signal is retransmitted. When a transmitting station or a receiving station does not have a V.34 facility after the V.8 protocol, the DIS signal indicating the non-provision of the V.8 facility is transmitted. Thus, when the V.8 protocol facility is provided with a facsimile apparatus, communication with a conventional apparatus having only a T.30 protocol is attained.

When a plurality of pages of image data are combined into one page of image data for transmission, the direct combination of the image data having different resolutions and the resulting recording of the image data on one record sheet while the image is partially expanded or reduced are prevented. In combining two pages of image data into one page of image data for transmission within a range in which the number of read lines of read image data does not exceed the number of available lines for recording per page at a transmission destination terminal, if the read resolutions of both image data are equal, the two pages of image data are combined into one page of image data for transmission, and if the read resolutions are different, the combination is not conducted and the image data of the respective pages are transmitted as the independent pages of image data. A facsimile apparatus minimizes the possibility of transmission disable due to a full state of a memory when a plurality of pages of image data having short sub-scan lengths stored in the memory are transmitted. The image data acquired by reading a document sheet by a contact sensor 13 is compression-coded by an encoder 103 of a read/write codec device 10 and it is stored in an image memory 6. After a plurality of pages of image data having short sub-scan lengths have been stored in the image memory 6, the image data are combined into one page of image data on a communication protocol and it is transmitted to a transmission destination apparatus through a modem 17 and a network control unit 18. When it is detected that a remaining capacity of the image memory 6 is small, the combination transmission of the image data is canceled and the image data stored in the image memory 6 is immediately read and transmitted.
摘要:
In a data communication apparatus, when performing a calling operation, an image transmission speed is assigned using a CCITT nonstandard reception command NSS after transmitting a dial signal, and the NSS is repeatedly transmitted at a predetermined time interval. Upon reception of a reception-preparation-confirming signal transmitted from an apparatus of a communication partner, a command, an identification signal and image data are transmitted at the image transmission speed based on information relating to the communication partner's apparatus which has been stored, so that the time required for communication procedures is shortened.
