Abstract: An E-mail communication apparatus that edits files attached to an E-mail and transmits the E-mail. The apparatus comprises a mail generating unit, a temporary-file generating unit, a temporary-file editing unit, an attached-file updating unit, and a transmitting unit. The mail generating unit generates a mail which is to be transmitted and to which a file is attached. The temporary-file generating unit generates a temporary file by copying the file attached to the mail that is to be transmitted. The temporary-file editing unit calls an application associated with the file attached to the mail that is to be transmitted, edits the temporary file and updates the temporary file. The attached-file updating unit replaces the file attached to the mail that is to be transmitted, with the temporary file copied. The transmitting unit transmits the mail to be transmitted.

Abstract: According to the present invention there is provided a piezoelectric type actuator wherein a compressive force is exerted on a piezoelectric laminate, using a coil spring having a relatively small spring constant and a coned disc spring having a relatively large spring constant, the said compressive force being in the range of 4.0 to 50 in terms of the ratio of the spring constant of the coned disc spring to that of the coil spring.Under the above construction, the performance of the piezoelectric laminate is not deteriorated under any conditions during use, and the size of the piezoelectric type actuator can be reduced.
