  • Publication number: 20050224844
    Abstract: A drain region 8 of a modulation transistor TM, which outputs a pixel signal in accordance with a photoelectric charge while a threshold voltage of a channel between a source region 7 and the drain region 8 is controlled by the photoelectric charge stored in a modulating well 5, is formed with a high concentration N+ layer 8a surrounding the collecting well 4 and the modulating well 5, and an N? layer accommodating the N+ layer 8a in the periphery of a ring gate 6 to become a diffusion layer with lower concentration than the N+ layer, thereby avoiding effects of the crystal defects of the drain region 8.

  • Publication number: 20020178219
    Abstract: When a client needs to repair an apparatus, a person in charge for transportation in a sales company visits the client to receive the apparatus. The sales company repairs the apparatus. When the sales company cannot repair the received apparatus, the sales company commissions the apparatus to a third party. The sales company returns the repaired apparatus to the client. A system for managing this service has a database which registers information on apparatuses held by said client even for those apparatuses which are to be repaired at different sections; and a server which accepts a repair request made by each client, acquires information on the apparatus to be repaired by referring to said database and executes a processes of receiving the apparatus, repairing the apparatus, and returning the repaired apparatus to said client.
