Filed: 2001-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a method or manufacturing a pressure sensor and a semiconductor substrate used for the same, which can be thinned and miniaturized, while keeping high performance. SOLUTION: Spacers 6 made of a polyimide on a semiconductor substrate 3 having a rear electrode 4, and the circumferential edge of a vibrating electrode film 8 is fixed on the spacers 6, thereby constituting a capacitor comprising the rear electrode 4, a space 9 (air) and the vibrating electrode film 8. A conversion circuit for converting the change in capacitance of the capacitor, due to the vibration of the film 8 to a voltage signal, is provided on the substrate 3. In this way, since the number of parts is smaller and the parts are smaller in size than those of the same type of sensor, the sensor can be thinned and miniaturized, while keeping its high performance. Furthermore, a silicon nitride film 7 serving as a polarization film is provided on the spacers 6 made of polyimide, to suppress the variation in thickness of a polyimide film, depending on individual devices.  As the result, variations in performance depending on individual devices can be suppressed, and a pressure sensor of high reliability can be obtained.

Title: Data communication program, computer readable recording medium having the same program recorded thereon, data communication equipment and data communication method
Inventor: MAE TAKEO
IPC: G06F13/00
Filed: 2001-03-31
Abstract: PROBLEM TO BE SOLVED: To more efficiently rewrite firmware irrespective of the transmission/ reception order of divided firmware. SOLUTION: When an email with firmware is received (S1007), it is judged whether the whole firmware data in a write-enabled state are made available (S1009). When the whole data are available, a message is down-loaded from a mail server to a printer controller. Firmware which is taken out is transmitted to a picture generation device (S1015) and the rewriting permission of the firmware is obtained (S107). Thus, firmware is collectively rewritten in a picture generating device-side. When the whole data whose write processing is enabled are not available, a system waits until firmware where a write processing is enabled is received while keeping the data in the mail server (S1021).
