IPC: G03G21/14
Filed: 2001-10-12
Abstract: PROBLEM TO BE SOLVED: To solve the problem that throughput is lowered more than necessary in the view of the reduction of warming at a part through which no paper passes since throughput in the case of using a paper of 150 mm length, e.g. with which warming at the part through which no paper passes is small is not different from that in the case of a paper of 249 length with which warming at the part through which no paper passes is large, because there is only one step of the distinction level of small sizes and the sizes are sorted only to a normal size not shorter than 250 mm and a small size shorter than 250 mm. SOLUTION: There are at least two steps of paper feeding intervals corresponding to a material to be heated shorter than a prescribed length, and a relation between the paper feeding interval I1 of the shortest material to be heated and the paper feeding interval I2 of a material to be heated which is longer than this by one step is I1<I2.

Title: Piezoelectric speaker panel and electronic device using the same
Inventor: WATABE YOSHIYUKI
IPC: H04R17/00
Filed: 2001-10-19
Abstract: PROBLEM TO BE SOLVED: To obtain a piezoelectric speaker panel having high sound pressure with good yield. SOLUTION: A sheet 102 for a piezoelectric element is cut into comparatively small pieces from a green sheet 100 formed of piezoelectric ceramics, including PZT (lead zircon titanate). A piezoelectric speaker 200 is obtained by using the cut pieces 102 for the piezoelectric element. The obtained small piezoelectric speaker 200 having a comparatively small area is sandwiched between flexible sheets 120A, 120B to obtain a piezoelectric speaker panel 300. A plurality of piezoelectric speakers 200 are connected in parallel. Cutting the sheet for the piezoelectric element into a comparatively large piece from the sheet 100 causes a defect at its large area portion. However, cutting the sheet for the piezoelectric element into a comparatively small pieces enhances yield.  Simultaneously driving the plurality of piezoelectric speakers obtains high sound pressure even if each piezoelectric speaker has a small driving area.
