Abstract: A device mounting board includes: an insulating resin layer; a wiring layer disposed on one main surface of the insulating resin layer; and a bump electrode connected electrically to the wiring layer and protruding on a side of the insulating resin layer from the wiring layer. A side surface of the bump electrode is curved inwardly toward the center axis of the bump electrode as viewed in a cross section including the center axis of the bump electrode, and the radius of curvature of the side surface changes continuously from a wiring layer end to a head end of the bump electrode.

Abstract: A tunable optical filter apparatus and method are disclosed. The apparatus may include a filter driver, a filter device, a detector device and a controller device. The filter driver generates a filter driver signal, including a dither signal. The controller device may be coupled to the detector device, the filter device and the filter driver. The controller device may receive the detector output signal and determine a ratio of the odd order harmonic signal to the even order harmonic signal with respect to the dither frequency. The controller device may also compare the ratio to a predetermined setpoint ratio and generate a control feedback signal for generating a new filter driver signal. The control feedback signal may be based on the comparison of the ratio of the odd order harmonic signal to the even order harmonic signal, to the predetermined setpoint ratio that corresponds to a desired filter operating frequency.

Abstract: A plurality of gravure rolls are rotated while being allowed to abut against a surface of a moving electrode hoop, thereby applying a coating fluid serving as a precursor of porous layers onto a plurality of linear mixture layers. In this way, a plurality of linear porous layers are formed on the associated linear mixture layers formed on the surface of the electrode hoop. In this case, the location at which each gravure roll abuts against the surface of the electrode hoop is controlled according to variations in the lateral location of associated one of the mixture layers independently of the other gravure rolls.

Abstract: A capacitor-equipped semiconductor device includes a semiconductor chip having a plurality of electrode terminals; a sheet-like substrate at least having a film capacitor; and a mounting substrate. The mounting substrate is provided on one side thereof with chip connection terminals and ground terminals. The chip connection terminals are disposed to correspond to the electrode terminals of the semiconductor chip. The ground terminals are disposed to correspond to the one electrode terminals of the film capacitor of the sheet-like substrate. The mounting substrate is provided on the other side thereof with external connection terminals connected to the chip connection terminals and the ground terminals and used to mount the mounting substrate on an external substrate.

Abstract: A computer system is provided for operating a graphical user interface (GUI) to enable a customer to select products. The system comprises a displaying mechanism displaying virtual shelves containing a plurality of first selectable elements in a form of product images arranged on the shelves to represent available products in a group of products selected by the customer, and a plurality of second selectable elements attached to respective first selectable elements. The second selectable elements are in a form of a price tags or price labels attached to the respective product images.

Abstract: A major object is to provide an improved semiconductor device capable of preventing occurrence of a crystal defect in a substrate. A source region is arranged at a surface of a semiconductor substrate and between first and second layered gates. A sidewall spacer is arranged on sidewalls, neighboring to a drain region, of the first and second layered gates. A sidewall spacer is not arranged on sidewalls, neighboring to a source region, of the first and second layered gates.

Abstract: A highly reliable semiconductor device is provided. A silicon nitride film having an opening is formed on a main surface of a silicon substrate. The opening is formed with a side surface. The silicon substrate is etched using the silicon nitride film as a mask to form a trench. The side surface of the silicon nitride film is altered in quality to form a silicon oxide film. A silicon oxide film filling the trench is formed in contact with the silicon oxide film. The silicon nitride film is removed with the silicon oxide film in contact with the silicon oxide film remaining.

Abstract: A communication network system comprising telephone networks concatenated with a packet switched data internetwork such as the Internet is provided. The network system transports voice signals therethrough while minimizing circuit overload in the telephone network circuits inputting signals to be transported through the internetwork. The telephone networks have a common channel interoffice signaling (CCIS) system using signaling system 7 (SS7) signals. The input load to the internetwork from the telephone systems is monitored by monitoring the control signals in the SS7 network. When an overload condition occurs or appears imminent all or part of the load is switched from the trunk circuits of the telephone network to the SS7 network following protocol translation and multiplexing with the control signals in the SS7 network. Provision is made for insuring excess capacity in the SS7 network before load is transferred.

Abstract: An apparatus for applying a uniform load to an object includes a load application element supported to be rotatable about a first axis and movable relative to the object along a second axis to obtain an initial contact sufficient to cause any needed rotation of the load application element until an alignment is obtained between the load application element and a load receiving surface of the object. Further movement of the load application element relative to the object results in a uniformly applied load or the test object.
