Patent JP-H02125677-A (JP)
Title: Manufacture of piezoelectric ceramic
Inventor: HONDA KOJI
IPC: H01L41/39
Filed: 1988-11-04
Abstract: PURPOSE:To produce orientated crystals easily and to obtain a piezoelectric ceramics having desirable characteristics by heating a compact mainly composed of ceramic powder successively from zone to zone. CONSTITUTION:A binder or the like is added to the principal component, ceramic powder of lead zirconate titanate for example to produce a compact. The compact is previously heated to a first temperature so as to prevent the compact from being subjected to thermal stress abruptly. The compact heated to the first temperature, typically 800 to 1000 deg.C, is further heated to a second temperature (typically 1200 to 1400 deg.C) successively from zone to zone. The compact is then left to stand or cooled by an appropriate cooling means. Thereby, orientated crystals can be produced easily. Thus, a piezoelectric ceramic element having desirable electric characteristics can be obtained.

Filed: 1994-11-16
Abstract: PURPOSE: To form and hold a uniform gap and to prevent the misalignment/ warpage, etc., of substrates at the time of sticking liquid crystal panels to each other. CONSTITUTION: A work 4 formed by holding adhesives between two sheets of the substrates to an integral shape is set on a work stage 6 and air is supplied from through-holes 11 to pressurize the work 4.

The pressure P2 is set at 0 to prevent the warpage of the substrates if the flatness of the substrates of the work 4 is good.  Further, the pressure P2 is set at a value to cancel the weight of the lower substrate to prevent the expansion of the spacing of the gap during curing in the case where the work 4 is pressurized by fixing the positions of its substrates of the work and holding the lower substrate in a movable state.
