Title: Electrostatic actuator and its manufacture
Inventor: SATO KAZUHIKO
IPC: B41J2/045
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To enhance durability so that an electrostatic attraction force of opposite members does not decrease and the opposite members are not attracted too much in an electrostatic actuator having the opposite members shifted relatively by an electrostatic force. SOLUTION: Hydrophobic films 53, 15 of HMDS(hexamethyl disilazane) are formed on surfaces of a bottom wall (common electrode) 51 of an ink chamber 5 and a segment electrode 10 of an ink-jet head 1 as an electrostatic actuator. The HMDS has smaller molecules than PFDA(perfluorodecanoic acid), etc., and therefore the hydrophobic film can be formed uniformly even if a gap G between opposite electrodes is small. Moreover, the HMDS hydrophobic film is highly durable and shows high film stability. The electrostatic actuator of high durability and high operation stability can thus be realized.

Title: Air cooling structure of liquid crystal display device
Inventor: TAKUSHIMA AKIRA
IPC: F25D1/00
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To efficiently guide the flow of a cooling fan because of a large rise in the temperature of a liquid crystal display part and further suppress the temperature on the whole by providing a blocking member which closes part of the cooling air intake of a ventilation path at the cooling air intake. SOLUTION: The ventilation part 40 is constituted between an incidence-side polarizing plate 2 and a liquid crystal 1, and the liquid crystal panel 1 and a projection-side polarizing plate 3. Then blocking members of heights H1 and H2 in, for example, a wall shape are provided above and below the cooling air intake 31 of the ventilation part 40. The lower part of the intake for cooling air is closed, so the capacity of passing air decreases and the flow faces down on the whole. Then the air is warmed and strikes on the lower end of the liquid crystal display part 30, so the air changes its direction upward and flows out of the upper part of the liquid crystal display part 30.  Consequently, air having passed above an intake part where the heating value is relatively small passes through the center part where the heating value is large and flows out of the upper part of the liquid crystal display part 30 where the heating value is small, so the rise in temperature becomes uniform on the whole.

Thus, demodulation by the QPSK system is attained and the SS communication system with a fast transmission speed is built up.
