摘要:
An optical modulation device is constituted by a first substrate provided with a plurality of first electrodes each comprising a plurality of portions electrically independent of each other, a second substrate disposed opposite to the first substrate and provided with a plurality of second electrodes each confronting a corresponding first electrode, and an optical modulation substance disposed between the first and second substrates so as to form a plurality of pixels each having a particular electrode structure. In the electrode structure, the optical modulation substance is sandwiched between each second electrode and said portions of said corresponding first electrode so as to form a series circuit providing a plurality of capacitance, thus reducing the capacitance for each pixel to improve a switching characteristic while minimizing a defective portion due to a short-circuit between the confronting electrodes.

In a surface acoustic wave apparatus, a surface acoustic wave element for obtaining a convolution signal is housed in a recess of a substrate. Since the surface acoustic wave element is housed in the recess of the substrate in this surface acoustic wave apparatus, the apparatus can be compactified. This effect of compactification is remarkable, because the surface acoustic wave element has an output electrode for obtaining the convolution signal and thus originally has a big element size. When a laminate substrate is used as the substrate, a configuration for effectively using surfaces of respective layers may be arranged in such a manner that output wiring of the convolution signal is separately formed in the layers. This further enhances the effect of compactification. There are further disclosed a spread spectrum signal receiver using the above surface acoustic wave apparatus for receiving a spread spectrum signal, and a spread spectrum communication system using the spread spectrum signal receiver.

The electron-emitting device is configured such that an inclination angle θ2 of a lower portion from a height-direction intermediate portion to the lower end is larger than the inclination angle θ1 of an upper portion from a lower edge of the concave portion to a height-direction intermediate portion. And, an electric resistance of a lower cathode portion which is a portion of the lower portion of the cathode is larger than that of an upper cathode portion which is a portion of the upper portion of the cathode.

An electron source substrate has an electron-emitting device consisting of a pair of device electrodes and an electroconductive thin film having an electron-emitting region; and metal wiring coupled to the device electrodes and made in a composition different from that of the device electrodes, on a substrate. A shortest distance between the conductive thin film and the metal wiring along an interface between the device electrodes and the substrate is not less than 50 μm. This configuration is able to effectively prevent diffusion of the wiring metal to the conductive thin film and to the electron-emitting region which can cause degradation of electron emission characteristics.

A liquid crystal device is constituted by a pair of substantially parallel substrates disposed opposite to each other to leave a gap extending two-dimensionally therebetween including a rectangular wider gap region and a peripheral frame-shaped narrower gap region surrounding the wider gap region, a plurality of spacers disposed in the gap over the wider and narrower gap regions, and a liquid crystal disposed between the pair of substrates so as to form pixels in the wider gap region. The spacers are disposed to have a larger volume per unit substrate area in the wider gap region and a smaller volume per unit substrate area in the narrower gap region, thus providing a uniform cell gap between the substrates.

摘要:
A matched filter has an input IDT and an output IDT, and also has a device for preventing propagating surface acoustic waves from diverging. By preventing the divergence of surface acoustic waves, signals obtained in units of electrode finger pairs of the output IDT are uniformed. Furthermore, this application also discloses the following arrangement. That is, an arrangement for converging surface acoustic waves is adopted, and the width of surface acoustic waves input to the output IDT is set to be larger than at least the crossing width of electrode fingers, nearest to the input IDT, of those of the output IDT, so that some surface acoustic waves propagate along non-crossing portions of the electrode fingers, on the input IDT side, of those of the output IDT. With this arrangement, the influence of the crossing portions of the electrode fingers, closer to the input IDT, on the surface acoustic waves input to the crossing portions of the electrode fingers, farther from the input IDT, can be relaxed.
