  • Patent number: 7388269
    Abstract: A diode such as a cell string bypass diode or a reverse-current preventive diode exhibiting excellent heat dissipativity and preferably sealed integrally in a solar cell module. An N terminal (11) consists thickness part of 0.8 mm or above, i.e. an N substrate part (12), one thin part, i.e. an N thin part (13), and a P connecting wire receiving part (24). In a state where a diode chip (31) is connected, the thicknesses of the entire lead terminals are substantially the same, the total value of the plane area of the N substrate part and the P substrate part is 200 (mm)2 or above, and the diode with a lead terminal is sealed together with the solar cell between the front surface material and the rear surface material for sealing the solar cell.

  • Publication number: 20070221919
    Abstract: The object of the present invention is to provide a diode that acts as a cell string bypass diode or a reverse-current preventive diode, has excellent heat dissipativity, and are preferably sealed integrally in a solar cell module. An N terminal 11 has an N substrate part 12 having an even thickness of 0.8 mm or more, an N thin part 13, which is one thin part, and an N connecting wire receiving part 14, which is the other thin part. A P terminal 21 has a P substrate part 22, a P thin part 23, and a P connecting wire receiving part 24. In a state where said diode chip 31 is connected, the thickness of the entire lead terminal is almost the same as that of the substrate part, i.e. the terminal, and the total of plane area of the N substrate part and that of the P substrate part is 200 mm2 or more. Said diode, together with the solar cell, is sealed between a front surface material and a rear surface material where the solar cell is to be sealed.

  • Patent number: 7129727
    Abstract: A defect inspecting apparatus in which a plurality of probes to measure electric characteristics of a sample including a fine wiring pattern are combined with a charged-particle beam unit includes graphic user interfaces (GUI) to simply control the plural probes. The apparatus includes a probe image processing unit to display the plural probes on a display; a selecting unit to select, from the probes displayed on the display, a probe to be operated; and a display unit to simultaneously display the probe selecting unit and information indicating that the selected probe is an operable probe, or the probe is in a non-selected state.

  • Publication number: 20040264421
    Abstract: Traffic that can be processed at a cell station is increased without reducing communication quality. When a channel is allocated to every time slot constituting a communication frame and radio control section receives a link channel establishment request from a personal station through a control channel allocated to any of the time slots, a control section notifies the personal station through the traffic channel of an allocation message indicating that the time slot allocated to the control channel will be allocated to a traffic channel. The transmission of the control channel is stopped when a predetermined time (a control channel transmission/reception duration) passes after the notification of the allocation message.
