摘要： A piezoelectric pressure sensor includes a generally elongated sensor housing, a pressure receiving plate disposed at a first end of the sensor housing with a first surface thereof serving as a pressure receiving surface for receiving a pressure applied from outside of the sensor housing, a pressure transmission member accommodated in the sensor housing with a first end thereof held in contact with a second surface of the pressure receiving plate, and a tubular piezoelectric element accommodated in the sensor housing with a first end thereof held in contact with a second end of the pressure transmission member. A pair of electrodes are formed on the external and internal surfaces of the piezoelectric element, respectively. An external charge detection member is held in contact with the external electrode for collecting charge generated by the external electrode and is encircled by a heat-shrinkable tube, while an internal charge detection member is held in contact with the internal electrode for extracting charge therefrom. A fixing screw is threaded into the sensor housing for holding in a prestressed fashion the piezoelectric element and the pressure transmission member against the pressure receiving plate. During assemblage of the pressure sensor, the heat-shrinkable tube undergoes a thermal shrinkage upon application of heat thereto, thereby compressing the external charge detection member radially inwardly against the external electrode.

摘要： A dichroic or trichromatic transparent display apparatus through which a background view is seen comprises a transparent substrate, a hologram formed on a rear face of the transparent substrate, a dispersion liquid crystal device disposed in front of a front face of the transparent substrate, a light source disposed for facing a side face of the transparent substrate and a transparent layer at least partially provided between the transparent substrate and the hologram. The refractive index of the transparent layer is smaller than that of the transparent substrate. A first light emitted from the light source and having a first wavelength is totally reflected by the boundary face between the transparent substrate and the transparent layer so that the first light moves to and is diffracted by a first region of the hologram where the transparent layer is not provided. A second light having a second wavelength is diffracted by a second region of the hologram where the transparent layer is provided. Thus, at least dichroic display is realized.

摘要： Members as an upper fixing screw, a piezoelectric element, a pressure transmitting member are located closer to region of an engine to be measured and the like than a fitting thread portion of a sensor casing so that a pre-stress on the piezoelectric element can be constantly maintained at a predetermined value, thus enabling pressure measurement with a high degree of accuracy. Further, a projecting portion or a spacer is provided on the backside of a pressure receiving surface in order to ensure the surface contact between the pressure transmitting member and the back surface of the pressure receiving surface, thus preventing the stress from concentrating on corners of the bottom surface of the pressure transmitting member.
