A laser welding method for stacked workpieces. A laser irradiation diameter that is irradiated on a surface of one workpiece among two stacked workpieces is set such that a laser irradiation diameter at a weld ending-edge portion is equal to or greater than approximately 1.5 times a laser irradiation diameter at a weld starting-edge portion. Thus, at the weld ending-edge portion, the material is melted in a wider area compared to a conventional example, and therefore, the melted material is supplied to the center portion of the weld ending-edge portion while the weld ending-edge portion is solidifying. As a result, a depth of the recess at the weld ending-edge portion can be made shallow enough to guarantee the welding quality of each of the workpieces.
摘要:
When a device searches a network, there is a case where the device is recognized as different devices as one searched by a protocol A and the other searched by a protocol B. In a proxy server 9300 for executing a protocol converting process in a network system, whether or not another protocol converting apparatus for executing a predetermined protocol converting process does not exist on the network is searched. When another protocol converting apparatus is searched on the network, whether or not the searched protocol converting apparatus has executed the protocol converting process is discriminated.

A butt welding system and a butt welding method of steel plate by which the quality of a product can be ensured. Butting portions of blank members (1,2) to be joined together are butted and a predetermined butting load is applied to the butting portion, wherein the blank members (1,2) are moved relatively in the direction of the welding line thus matching the butting portions. Protrusions and recesses formed on each butting portion of each blank member (1,2) are flattened, whereby linear precision at each butting portion of each blank member (1,2) is enhanced as compared with a case where the butting portions are not matched. Since the gap is reduced extremely at the butting portion, welding is facilitated at the butting portion. Good welding beads are thereby obtained at the butting portion and the quality of a product is ensured.

A deformable mirror includes a deformable section on which a reflecting surface and a COM electrode are formed, a fixing section which fixes the deformable section, a driving and sensing electrode (driving force generating unit) which has a plurality of driving and sensing electrodes provided facing the COM electrode, and which drives the deformable section by applying an electric potential difference between the COM electrode and the driving and sensing electrode, and a capacitance detecting circuit which detects simultaneously a plurality of capacitances between the COM electrode and the driving and sensing electrode.
摘要:
A service proxy processing method is used with a network service system in which a service providing device connected over a network for performing predetermined capability processing can communicate with a plurality of client devices for performing network connection capability processing for recognizing connection status of each service providing device over a network. Each service providing device has a proxy process step of specifying a specific communications capability in response to a communications capability request from any client device when a predetermined service providing process is not performed in a predetermined period, allowing any service providing device in a network to perform as a proxy a communications process based on the specified specific communications capabilities, and making a transition to a network sleep status not recognized by a client device in the network.
摘要:
A network information management unit in which a memory resource that requires the storage of a network information management database is utilized in distributed fashion, as a result of which a single agent need not be equipped with a large-scale memory. The management unit, which is connected to a network and mounted on a network-capable image processing device capable of being shared by a plurality of clients, is constituted by a plurality of agents distributed on a plurality of logically independent controllers that construct the image processing device. Each of the plurality of agents communicates with one another, and generates a network management information response to a network management information request, which has been issued by a network information manager, after each agent has processed the network management information request in distributed fashion.

An ultrasonic actuator driving apparatus which drives an ultrasonic transducer formed by alternately laminating a piezoelectric plate and an internal electrode, by applying a frequency signal to the ultrasonic transducer, includes an oscillating unit which generates the frequency signal for driving the ultrasonic transducer, a driving unit which amplifies the frequency signal and applies the signal to the ultrasonic transducer based on an output from the oscillating unit, a vibration information detecting unit which detects vibration information of the ultrasonic transducer, and, a control unit which detects a frequency near a resonant one of the ultrasonic transducer based on the vibration information, sets the detected frequency as a driving frequency of the ultrasonic transducer, and controls the oscillating unit so as to generate the frequency signal based on the driving frequency.
摘要:
On the basis of control information of an image received from an external device via an external parallel interface, a frame memory control unit stores image data, which has been transferred from the external device, in a band memory B obtained by partitioning a frame memory into band memories A and B. The frame memory control unit subjects the image stored in the band memory B to image processing based upon the received control information, stores the processed results in the band memory A and then sends image data, which is obtained by image-processing the stored results, to a printer or to the external device. Accordingly, highly sophisticated image processing can be achieved with a minimal memory capacity.
摘要:
A client device issues an event notification request to a service-providing apparatus, and notifies the service-providing apparatus whether an event processing unit which processes the event for which the notification request has been issued is active. Upon detecting the occurrence of an event, the service-providing apparatus searches for client devices whose notification requests for the event have been registered, and notifies the occurrence of the event to a client device in which an event processing unit which can process the event is active.
