Filed: 1990-04-20
Abstract: PURPOSE:To improve the security function for facsimile communication by converting received picture data to a cipher data to store it in a storage memory and deciphering this cipher data by an inserted IC card to print out data. CONSTITUTION:An ciphering part 3 converts reception picture data 20 to cipher data 21 to store it in a storage memory 4, and when an IC card 10 is inserted, a transfer part 5 takes out cipher data 21 in the storage memory 4 and transfers it to the IC card 10. The IC card 10 deciphers this cipher data 21 to return deciphered data 22, and the transfer part 5 transfers deciphered data 22 received from the IC card 10 to a recording part, and the recording part prints out this data. Since reception picture data 20 is converted to cipher data 21 in this manner, the normal print output cannot be obtained unless the IC card 10 is inserted. Thus, the security function is improved.

Title: Photoelectric conversion device
Inventor: TANAKA AKIMASA
IPC: H01L31/10
Filed: 1989-04-26
Abstract: PURPOSE:To increase detection sensitivity of a photoelectric transducer by a method wherein donar is formed in an N-type impurity region, insulating layers are positively charged, electron in the impurity region is attracted, electric field is not concentrated at end-portions of a PN junction surface, and the increase of leak current is prevented. CONSTITUTION:Donar is formed in an N<+> type diffusion region 14, and oxide layers 12, 16 are positively charged, so that electron in the diffusion region 14 is attracted. Hence a depletion layer formed at end-portions 15a of a PN junction surface 15 is stretched in the entering direction under a light shielding layer 13, and electric field is not concentrated. Since the oxide layer 12 is thinnly formed, oblique incidence ultraviolet rays scarcely exist, and the amount of ultraviolet rays projected under a light shielding layer 13 is remarkably reduced. Hence the increase of leak current generated mainly at end-portions of a P-N junction surface by the irradiation of ultraviolet rays is almost blocked, and detection sensitivity of a photo diode array can be stably improved.
