摘要:
In an antenna apparatus, at least one choke in the form of a groove is arranged between a transmitting antenna and a receiving antenna. The choke functions to suppress the mutual electromagnetic coupling between the transmitting antenna and the receiving antenna. The depth of the choke is in a range from 0.15, to less than 0.225λ where λ is a wavelength of a carrier wave.

A control system for an internal combustion engine having fuel injectors for injecting fuel into a combustion chamber of the engine. A fuel property is estimated based on a combustion state of the fuel injected into at least one cylinder of the engine. The fuel injectors are controlled so that a specific amount of fuel is injected into the at least one cylinder and an amount of fuel corresponding to an operating condition of the engine is injected into cylinders other than the at least one cylinder. An additional fuel injection is performed after the fuel injection of the specific amount with respect to the at least one cylinder, for example, when a torque difference parameter indicative of a difference between a torque generated by the at least one cylinder and a torque generated by the other cylinders is equal to or greater than a predetermined threshold value.

摘要:
A solder bonding method and a solder bonding device are provided, in which solder is melted, and heating of electrode portions is performed by irradiating laser light to an inner side of a region where electrodes portions are provided, making the temperature difference between the electrode portions and the melted solder smaller to improve the wettability of the solder and increase bonding reliability. The solder bonding method and the solder bonding device perform bonding of the electrode portions that are formed on an object to be bonded by melting the solder. After supplying the solder onto the electrode portions before melting, a laser is irradiated to the solder and to the electrode portions in the periphery of the solder. The solder melts, and the electrode portions are heated. The wettability of the solder with respect to the electrode portions thus improves, and the reliability of an electrical connection between the electrode portions can be increased.

Provided are a solder ball bonding method and a solder ball bonding device for performing bonding of a plurality of electrode portions formed on objects to be bonded by melting solder balls. The solder balls are suctioned by using a plurality of suction nozzles that follow the electrode portions of the objects to be bonded, and conveyed onto the electrode portions. A laser irradiation portion that is positioned above the suction nozzles is then moved in a direction along which the suction nozzles are arranged, while the solder balls are irradiated with laser light passing through suction openings of the suction nozzles by using the laser irradiation portion. Accordingly, it is possible to melt the plurality of solder balls on the electrode portions by using only a single laser irradiation portion.

The present invention provides a magnetic head construction, a connection method and a connecting device by which excellent electrical connection can be carried out between a core electrode and a substrate land face on a flexure in a magnetic head employing the piggy back system. In order to attain the object of interest, in the present invention, a fine adjustment actuator is arranged between a core and a flexure; a projection portion which is projected from the fine adjustment actuator when viewed from the flexure is provided in the core; a hole is provided in the position, on the flexure, corresponding to the projection portion; only the core is fixed by a support portion provided through the hole portion and a clamp pin without applying any load to the fine adjustment actuator; and while maintaining this fixing state, an electrode and a substrate land are bonded to each other with a wire.
摘要:
A method for mounting a head stack assembly (HSA) circuit assembly is disclosed. A flexible circuit substrate may be coupled to a stiffener. The stiffener may be a metal, such as aluminum, or some other stiff and durable material. The flexible circuit substrate may be made of an organic material and may have a series of electronic leads embedded in the flexible circuit substrate. The flexible substrate may be coupled to the stiffener by an adhesive or laminated onto the stiffener. The stiffener may be mounted onto the actuator arm by soldering or by laser welding.
摘要:
The invention provides an exhaust gas purification device that can prevent deterioration of the emission during a regeneration process for a particular filter for trapping particulates contained in the exhaust gas.Particulate filter regeneration timing determining unit estimates the amount of particulates trapped by the particulate filter to determine the filter regeneration timing based on the estimated particular amount. In response to the regeneration timing determination, heating unit heats the particulate filter to raise an exhaust gas temperature, so that a particulate filter regeneration process starts. At this time, intake air amount reducing unit reduces the intake air amount to raise the exhaust gas temperature while combustion maintaining unit controls the combustion in the internal-combustion engine so as to be maintained in a desired condition.
