摘要： According to one embodiment, a portable electronic device includes a touch-screen display. The electronic device executes a function which is associated with a display object corresponding to a tap position on the touch-screen display. The electronic device includes at least one microphone, a speech processing module configured to process an input speech signal from the at least one microphone, and a translation result output module configured to output a translation result of a target language. The translation result of the target language is obtained by recognizing and machine-translating the input speech signal which is processed by the speech processing module. The speech processing module detects a tap sound signal in the input speech signal, the tap sound signal being produced by tapping the touch-screen display, and corrects the input speech signal in order to reduce an influence of the detected tap sound signal upon the input speech signal.

摘要： An optical system for image projection is disclosed which is capable of improving contrast while suppressing reduction of light amount. The optical system includes a converging optical system, and a polarization beam splitting surface transmitting an incoming light flux having a first polarization direction from the converging optical system, to introduce it to the image-forming element and causing light having a second polarization direction, of an outgoing light flux from the image-forming element, to proceed to a projection optical system. In a first cross-section parallel to a normal to the polarization beam splitting surface, the converging optical system has a configuration causing an incident angle on the splitting surface of a light ray passing through a barycenter of intensity distribution of the outgoing light flux to be larger than an incident angle thereon of a light ray passing through a barycenter of intensity distribution of the incoming light flux.

摘要： The invention relates to a method of manufacturing an electron emission element, having a step of forming a pair of element electrodes on a rear plate, a step of forming a conductive film to connect the element electrodes, and a forming process of forming an electron emitter on a conductive film by applying power to the element electrodes. The method has an impurities elimination process for eliminating impurities adhered to an electron emitter, by giving element electrodes a voltage of polarity opposite to that in ordinary operation in a vacuum atmosphere, through a baking process, after carbon is adhered to an electron emitter by an activation process. The impurities adhered to the electron emitter can be securely eliminated by performing the impurities elimination process, without using an exclusive processor.
