A microphone apparatus for processing and outputting an output signal of a microphone array including at least nine microphones includes a directivity function processing circuit that converts the output signal of the microphone array into a unidirectional signal and that outputs the unidirectional signal. The directivity function processing circuit expands a directivity function whose variable is an incident angle of an acoustic wave into a Fourier series up to at least third order. The variable in the expanded expression is produced from output signals of the microphones forming the microphone array.

The object of the present invention is to efficiently dissipate heat from the upper and lower main surfaces of a semiconductor device carrying a semiconductor element. A semiconductor device (1) is provided with an insulating substrate (10A), an insulating substrate (10B) provided so as to face the insulating substrate (10A), and a semiconductor element (20) disposed between the insulating substrate (10A) and the insulating substrate (10B) and having a collector electrode and an emitter electrode provided on the side opposite to that of the collector electrode. The collector electrode is electrically connected to a metal foil (10ac) provided on the insulating substrate (10A), and the emitter electrode is electrically connected to the metal foil (10bc) provided on the insulating substrate (10B). As a result, heat generated by the semiconductor element (20) is efficiently dissipated from the upper and lower main surfaces of the semiconductor device (1).

A DMA controller controls DMA transfer in an information processing system. Input and output devices are a transfer source or a transfer destination in DMA transfer and request DMA transfer. A DMAC activating unit is provided with an event monitoring unit and an event register. The event register registers an event subject to monitoring. The event monitoring unit detects an event generated in the input and output devices and determines whether the detected event matches an event registered in the event register. If it is determined that the events match, the event monitoring unit activates the DMA controller.

The object of this invention is to provide a method for producing a component for vacuum apparatus and a resin coating forming apparatus capable of easily forming a resin coating on an internal flow path complex in shape.The resin coating forming apparatus (21) comprises a monomer vapor supplying unit (23), a vacuum pumping line (24) for transporting monomer vapor, a connection portion (24c) connectable with the internal flow path of a component (22A) provided on part of the vacuum pumping line (24), and a temperature adjusting unit (31) for depositing the monomer vapor onto the internal flow path of the component (22A) connected with the connection portion (24c) to form a resin coating. The above arrangement permits the formation of a uniform, high-coverage resin coating on the internal flow path of the component (22A) by merely exposing the internal flow path to monomer vapor.

In producing a semiconductor device, a solder alloy is prepared to contain antimony in a range of from 3 to 5 wt %, a trace amount of germanium, and a balance of tin. An insulative substrate having conductor patterns on both surfaces thereof is prepared, and a heat sink plate is mounted on a back surface of the insulative substrate by a soldering process using the solder alloy at a temperature ranging from 310 C.° to 320 C.° in a hydrogen reducing furnace. A semiconductor chip is mounted on a front surface of the insulative substrate.

A lifting plate provided in a sheet accommodating member is locked at a position, to which the lifting plate is downwardly turned against a pushing force of a spring, by a locking mechanism having a locking member configured to lock the lifting plate, and also having a lock releasing lever configured to release locking of the lifting plate by the locking member. When the sheet accommodating unit is mounted, the lock releasing lever is made to abut against a lock release member. Thus, the lock releasing lever is moved integrally with the locking member in a lock release direction. When the sheet accommodating unit is drawn out, the lock releasing lever is made to abut against the lock release member. Thus, the lock releasing lever is singly moved in a direction opposite to the lock release direction to maintain the locking of the lifting plate by the locking member.

An inkjet printhead includes: a cavity unit having aligned nozzles, pressure chambers correspondingly aligned, and a common-chamber member having a common chamber connected, at an introduction place, to an ink source to receive and distribute ink to the pressure chambers, and extending along the pressure chambers row to overlap each pressure chamber when seen in the superposition direction, and a cross-sectional area of the common chamber perpendicular to its longitudinal direction gradually decreases in a direction away from the introduction place, at a portion remote from the introduction place; an actuator on the cavity unit to pressurize the distributed ink to eject ink droplets from the nozzles; and a compensating member having a rigidity lower than that of the common-chamber member, and being disposed in contact with the ink, at the remote portion so that a supporting rigidity of the common-chamber member is substantially uniform along the pressure chambers row.

Disclosed are a semiconductor device, a method for manufacturing the same, and a method for mounting the same. The method for manufacturing a semiconductor device includes the steps of: preparing a package film having a planar configuration whose region is divided into a device-mounting film portion having a device hole forming therein, an external-connection film portion, and a bent portion located between the device-mounting film portion and the external-connection film portion, an external electrode pad being formed on the external-connection film portion on a first surface side of the package film, an inner lead being formed in such a manner as to lead from the device hole to the external electrode pad via the bending portion; mounting a semiconductor chip on the device-mounting film portion on the first surface side by bonding the inner lead to an electrode pad of the semiconductor chip in a region where the device hole is formed; and bending the external-connection film portion at the bending portion 180° toward a second surface side of the package film and fixing the same. The method for mounting a semiconductor device on a mother board in close contact therewith includes the steps of: depositing solder balls on electrode pads of the mother board; and placing the semiconductor device on the mother board and melting the solder balls so as to electrically connect the electrode pads of the mother board and the external electrode pads of the semiconductor device.
摘要:
An ink-jet head comprises an ink chamber, a pressure chamber, an actuator, a constriction, and a nozzle. The ink chamber contains ink. To the pressure chamber, ink is supplied from the ink chamber. The actuator is applied with a drive pulse to thereby change the pressure of ink in the pressure chamber. The constriction is disposed between the ink chamber and the pressure chamber and has a passage width narrower than that of the pressure chamber. The nozzle communicates with the pressure chamber and ejects ink in association with the pressure change of the ink in the pressure chamber. A ratio Ra/Rb between a flow resistance Ra of the constriction and a flow resistance Rb of the nozzle is 0.48 to 1.26.
