Title: Laminated piezoelectric actuator element
Inventor: TAKAHASHI YOSHIKAZU
IPC: H01L41/083
Filed: 1990-03-19
Abstract: PURPOSE:To improve reliability of a laminated piezoelectric actuator element and to obtain an element having small deviation loss, deviation distribution and internal stress by stacking a plurality of laminated longitudinal effect piezoelectric element subunits, and reducing the area of a junction member for bonding between adjacent subunits equal to or smaller than the area of inner electrodes. CONSTITUTION:A laminated piezoelectric actuator element 10 is composed of a laminated longitudinal effect piezoelectric element subunit 5, a junction member 3 for bonding adjacent subunits, and outer electrodes 6 for supplying a drive voltage to a piezoelectric ceramic layer 2. In the unit 5, an inner electrode layer 1, outer electrodes 6 and an electrode lead 11 are screen printed on the layer 2 of substantially square-shaped lead titanate-zirconate, and laminated. A piezoelectric inactive part 7 in which the drive voltage is not applied exists on the periphery of the subunit 5. Since the number of laminated layers is small, control of the thickness of the layer, the uniformity of crystal grain size and the denseness in the case of sintering are facilitated, and decreases in reliability of piezoelectric properties, insulating properties are entirely eliminated.

Title: Liquid crystal display element
Inventor: OKUMURA OSAMU
IPC: G02F1/133
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To achieve a bright display with less coloring property, and to prevent a display from being viewed as double-image by using a liquid crystal through which incident light on a liquid crystal cell becomes a linearly polarized light on the reflection plane of a reflection means. SOLUTION: Linear polarized light made incident on a liquid crystal cell through a polarizing plate 2 passes through a crystal liquid layer two times, and it is again made to pass through the polarizing plate in the same state of the linearly polarized light. Namely, the incident light from the left becomes linearly polarized light through the polarizing plate 2. And then, while a phase difference is being produced by a double refractivity of liquid crystal molecular 16, the light generally changes into elliptically polarized light. If this light is linearly polarized light when it has reached a reflection plate 4, it follows exactly the same steps of polarization changes as those in the outward path to revert to the original linearly polarized light, and is able to pass through the polarizing plate 2 without loss of light quantity.  Thus, the display can be made brighter by a light quantity equivalent to an efficiency of the polarizing plate 2 by using solely the polarizing plate 2.

Abstract: PURPOSE:To attain to enlarge a range capable of absorbing the output of a turbine, by constituting the suction and exhaust lines of a compressor as a closed loop and changing the air density of the closed loop in a wide range from almost vacuum to a high pressure air state. CONSTITUTION:Air compressed by an air source 2 is adjusted to predetermined pressure by a pressure control valve 4 and sent to the turbine 7 of an overcharger through a stop valve 6. The turbine 7 issues the output corresponding to the introduced amount of air. The compressor 9 directly connected to the turbine 7 allows air to recirculate through a closed loop consisting of a pressure control valve 21, an air cooler 22 and a branched pipe 23 to absorb the output of the turbine 7. The regulation of the absorption of load is performed as follows. That is, the air of the closed loop is exhausted to a vacuum line 29 to lower the air density of the suction line of the compressor 9 while air is introduced into the closed loop from a high pressure air line 26 to enhance air density and the exhaust and introduced amounts of air are adjusted by a pressure control valve 24.

Abstract: PURPOSE:To diagnose a power source switching circuit even in a failure of a DC/DC converter by arranging another reverse current preventing diode between a power source switching circuit and a reverse current preventing diode so as to connect respective cathodes with each other. CONSTITUTION:A microcomputer 11, to which electric power is supplied from a circuit system power source 15 via a power source line Y, turns on a power source limiting circuit 8 on the basis of an acceleration signal fed to an input terminal A and supplies electric power to a detonator 9 for operating an air bag and the like.
