Abstract: An ion source is provided. The ion source includes a plasma generation chamber, a plate member, and an extraction electrode. The plasma generation chamber is supplied with a halogen-containing material. The plate member is provided on an end of the plasma generation chamber located on a side toward which an ion beam is extracted. The extraction electrode is disposed downstream of the plate member. The plate member is formed with a gas supply passage via which hydrogen gas is supplied to the extraction electrode.

Abstract: To provide an information processing system and an information processing method capable of increasing the effect of advertising distribution. An information processing system includes: a mail creation unit for distributing, to multiple users, mail including link information that can identify the users; and a cushion page creation unit which, when access based on the link information is received from a client of a user, transmits a web page to the client to cause the client to receive a cookie for transmitting attribute information according to an attribute of the user to an ad network server based on the link information.

Abstract: An encoder according to the present invention includes an encoding unit for encoding an input video or audio signal into an elementary stream; a creating unit for creating elementary stream buffer index information on the elementary stream; and a storing unit for storing the elementary stream encoded by the encoding unit and the elementary stream buffer index information created by the creating unit.

Abstract: A contact pin aligned in an IC socket body can be made by stamping, the pin comprising a base, a connecting terminal, a first contacting piece provided at the corresponding position to said connecting terminal and having a slanted or vertical contacting face, a second contacting piece connected to said base through a spring part, and a contacting face to make a conductive contact with the other face. The second contacting face can instead be angular to make a linear contact.
