  • Patent number: 7454317
    Abstract: There is provided a system and method for monitoring an apparatus from a remote location. A vendor-side computer obtains operating state data obtained by a monitoring device provided in an apparatus via a communication line, and monitors the operating state of the apparatus from a remote location. Maintenance data at a part replacing time is transmitted from the apparatus, and the vendor-side computer that has received maintenance data calculates an optimal replacement period of a part based on this. The calculated optimal replacement period of each part is sent to a plant. The plant feeds the optimal replacement period back to the operating of the apparatus.

  • Publication number: 20060010087
    Abstract: A business practitioner who offers a maintenance service for a machine (15) quantifies the productivity of the machine (15) in a predetermined service period (S42). The business practitioner compares the quantified productivity with a predetermined productivity reference, and calculates the difference between them (S43). The business practitioner determines a charge amount for the maintenance service in the service period based on the calculated difference (S45). Due to this, charging is realized which can satisfy both of the user of the machine (15) and the maintenance business practitioner.

  • Patent number: 5436571
    Abstract: A probing test method including contacting probe of a probe card with pad on an IC chip on a semiconductor wafer, relatively moving each of the probe along the top of each of the pad, and sending test signal to the pad through the probe. Oxide film on the top of each of the pads can be removed by relative motion between each probe and each pad at an area where they are contacted with each other, contact resistance between the probes and the pads can be reduced to a greater extent, and test signal can be more reliable transmitted between the probes and the pads.

  • Patent number: 5374888
    Abstract: A method for positioning and testing an object to be tested wherein the surface of an object to be tested for electrical characteristics is brought into contact with a test probe. The side of the object opposite the surface to be tested is held by a suction device on the end of one of many arms which are attached to a rotating shaft. The object is then transported to a position to bring it into contact with the test probe where testing is performed to determine whether or not the object is faulty. If necessary, the arms are manipulated in an up and down and an in and out direction with respect to the shaft, and the suction device rotated, to maintain the object to be tested in a proper orientation.
