Abstract: A diffractive-refractive achromatic lens that has a positive resultant power includes a refractive lens system and a positive diffractive grating. The refractive lens system is provided with a positive lens having relatively small dispersion, a negative lens having relatively large dispersion and an additional refractive lens. The additional refractive lens is a positive lens. The refractive lens system exhibits longitudinal chromatic aberration that is substantially proportional to wavelength such that the back focus of the refractive lens system decreases as the wavelength becomes shorter. The positive diffractive grating corrects the longitudinal chromatic aberration of the refractive lens system. The condition 0.005<f/fD<0.2 is satisfied where f is the focal length of the entire lens system, and fD is the focal length of said positive diffractive grating.

Abstract: A POP access section accesses a POP3 server using a first user ID/password registered in a user ID registration table, fetches message information from a mailbox of the user ID, and stores it to RAM. A message information extracting section extracts necessary information from the message information, and stores it to be associated with the user ID. Thereafter, a reception list generating section reads message information of all user IDs from RAM, and generates a reception list. Sequentially, the reception list generating section outputs the generated reception list. A user, who has seen the reception list, instructs the POP access section to fetch an e-mail message from a panel control section. This improves communication concealment.
