A key structure applicable in an electronic device for pressing an electrical button of the electronic device is disclosed. The key structure includes an annulus section for fixing the key structure in the electronic device, and a pair of key sections, each of which extends from the annulus section and has a protruding section and a retention section, wherein the protruding section protrudes out of an inner wall of the key section to prevent the key section from sinking, and the retention sectio...

An optical reader capable of reading a bar code in a mounted state when an article carrying the bar code passes and of reading bar codes set in array on a menu sheet in a hand-held state has been disclosed. The optical reader comprises a light source, a scanner that is driven by a drive and scans light emanating from the light source, a plurality of reflection mirrors that reflect scanning light scanned by the scanner and create a scanning pattern composed of a plurality of scan trajectories, a ...

A control surface has one or more soft devices for which functionality may be assigned, a central processing unit (CPU), including operating code, for managing at least functionality of the soft devices on the control surface, and a network connection for connecting to one or more computerized appliances. The control code assigns individual ones of the one or more soft devices to specific functions of an individual one of the one or more computerized appliances. There may be a variety of differe...

A inflatable product for an inflatable body includes a casing with an airway adapted to communicate with an interior of the inflatable body, and a resilient element movably positioned inside the casing to define with the casing a space therebetween. An on/off switch is adapted to connect to an air pump,A driving element is movably positioned inside the casing to be in response to the movement of the resilient element so as to selectively activate the on/off switch to activate the air pump. A rec...

A monopole antenna capable of implementing an MIMO system, which includes a ground part formed of plate metal, a monopole antenna element connected to one side of the ground part and formed of strips bent multiple times, an auxiliary antenna element connected to one side of the ground part and disposed adjacent to the monopole antenna element to electrically connect to the monopole antenna element, and a short-circuit part interconnecting the monopole antenna element and the auxiliary antenna el...

A lens cap for a title for removably covering a photograph lens of a video camera which is capable of photographing an object at a very short distance to carry out a title photographing is disclosed in which a part of the lens cap is provided with a region capable of removably attaching a title element such as a title recording paper thereto. Therefore, the title phoptographing in such as a macro mode with the above-described video camera can be achieved with the lens cap attached onto an expose...

Provides methods, apparatus and systems for determining an applicable policy for an incoming message having a service-level addressing element. A method includes the following steps: a) applying a potentially applicable policy (P1) on the incoming message to make the service-level addressing element of the incoming message visible, b) if the service-level addressing element of the incoming message gets visible and is the one to which the currently applied policy (P1) is associated, the currently...

A tunneling transistor is provided as an effective means for miniaturization of a semiconductor integrated circuit having nonvolatile memory. An insulating layer is disposed on a silicon substrate. A source and a drain are disposed on the insulating layer, with an insulator of a few nanometers in thickness that provides a tunnel barrier being interposed between the source and the drain. A ferroelectric layer that exhibits spontaneous polarization is disposed directly above a region of the source...

Organic photoprecursors of amines are provided for use in photosensitive imaging systems, finding particular application in the preparation of lithographic printing plates. Said photoprecursors generate free amines on exposure to long wavelength UV or visible radiation, have high solubility in organic solvents, and include photolabile 2-nitrobenzyl functional groups. Methods for the synthesis of the photoprecursors are described, and the use of the said photoprecursors for the production of prin...

Combustion process especially applicable to cement works, in which process it is desired to use fuels which are difficult to ignite. To do so, a flame comprising a primary zone and a secondary zone is created. The hot primary zone is created using an oxy-fuel flame, which makes it possible to preheat the fuel which is difficult to ignite so as to raise it to the suitable temperature in the secondary zone where it burns, with air, in order to create the main flame. Applications: cement, metallurg...
