摘要:
The invention provides a communication apparatus used inside a house, a communication system connected thereto, a communication process, and computer program used therefore. The communication apparatus of the present invention connected via a network to one or more terminal appliances in the house, communicates with the outside via two or more different communication configurations including a first communication configuration with a high speed digital transmission technique and a second communication configuration providing service for telephone subscribers. The communication apparatus is characterized in recognizing a situation thereby to disconnect the first communication configuration and to use only the second communication configuration for communication with the outside.

A communication system includes an information terminal apparatus having at least a data collecting portion for collecting appliance information of an appliance, a data processing server apparatus and a communication device which can be communicated with the information terminal apparatus, and first and second communication networks for connection between the information terminal apparatus and the data processing server apparatus. The first communication network is a communication configuration with a high speed digital transmission technique, and the second communication network is another communication configuration providing service for telephone subscribers. The information terminal apparatus communicates the appliance information with the data processing server apparatus through the first communication network, and uses the second communication network for communicating a particular appliance information with the communication device.

An acoustic matching member that is incorporated into an ultrasonic transducer for transmitting and receiving ultrasonic waves, includes: at least two layers including a first layer and a second layer that have different acoustic impedance values from each other. The first layer is made of a composite material of a porous member and a filing material supported by void portions of the porous member, the second layer is made of the filling material or the porous member, and the first layer and the second layer are present in this stated order. A piezoelectric member is disposed on a side of the first layer of the acoustic matching member to form an ultrasonic transducer or an ultrasonic flowmeter. The acoustic matching member does not have independent intermediate layers between the layers, so that delamination hardly occurs and the difficulty in the designing associated with the presence of intermediate layers can be avoided.

An infrared detecting capacitor formed of a ferroelectric film has its capacitor portion supported by first and second interconnecting lines to be held on an Si substrate located on both sides of a trench. A lower electrode is coupled with the first interconnecting line while an upper electrode is coupled with the second interconnecting line. The capacitor portion is a rectangle in shape in plan view without small triangular sections opposite to each other in the diagonal direction.

In a process using a single-layer or multi-layer resist, by using a resist material comprising an acid-decomposable polymer, an acid generator and a conducting polymer or a resist material comprising a monomer to be made reactive by an acid, an acid generator and a conducting polymer, there can be formed a fine pattern precisely without inviting charging during charged beam writing.
摘要:
The reverse side of a substrate made of stainless steel is subjected to electro-discharge machining using a thick electrode having a diameter of about 10 .mu.m, thus selectively etching other part than the edge of the reverse side of the substrate. This electro-discharge machining causes the other part than the edge of the substrate to be thinned to a thickness of about 10 .mu.m. The surface of the substrate thus thinned is subjected to electro-discharge machining using a slender electrode having a diameter of about 3 .mu.m, thus forming a pattern having a predetermined configuration in the surface of the substrate. Further, the surface of the substrate is etched with the use of the slender electrode, so that the pattern of the silicon substrate is pierced, thus forming a pattern having vertical through-holes. Thus, by using, as a mask material, a substrate solely made of stainless steel as it is, there can be produced a stencil mask which is excellent in mechanical strength and thermal stability and which is not thermally distorted.
