摘要:
In a digital camera having multiple optical systems, multiple image capturing elements are effectively driven to reduce power consumption. A digital camera has a first image capturing optical system having a lens and a first image sensor and a second image capturing optical system having a lens and a second image sensor. A controller and timing generator selects the image signal from the first image capturing optical system while controlling an operation or power of the second image sensor and a clock driver to be OFF when the zoom position falls within a first zoom range. When the zoom position falls within a second zoom range, the image signal from the second image capturing optical system is selected while an operation or power of the first image sensor and a clock driver is controlled to be OFF. An operation or power of the image capturing optical system which is not selected is stopped so that power consumption is reduced.

A digital camera enables high-speed zooming operation without use of a zoom lens. Light originating from a fixed-focal-length lens is split into two beams by a beam splitter, to thus form respective images on a first image sensor and a second image sensor. The first image sensor and the second image sensor are equal to each other in terms of the number of pixels, but differ from each other in terms of a pixel size. The first image sensor acquires a wide image, and the second image sensor acquires a telephotography image. An output is produced by means of switching between the first image sensor and the second image sensor, in response to zooming operation. When the image from the first image sensor is recorded, focus detection is performed by use of an image signal from the second image sensor, to thus effect automatic focusing.

Disclosed is a technique for quickly detecting a defect of a portion welded by laser beam welding. Specifically disclosed is a welding step in which a welding device is used, the welding device welding an object to be welded with a pulsed laser. In the welding step, a first photodetector receives only infrared rays having a wavelength allowing detection of a keyhole formed in a molten pool from among infrared rays radiating from a welded portion during the welding of the object, and an analyzer determines quality of the welded portion on the basis of intensity of the infrared rays received by the first photodetector.

There is provided a plasma processing apparatus capable of stably generating plasma by suppressing oscillation of a plasma potential, and capable of preventing contamination caused by sputtering a facing electrode made of metal. A high frequency bias power is applied to an electrode within a mounting table for mounting a target object thereon. An extended protrusion 60 is formed at an inner peripheral surface of a cover member 27. The extended protrusion 60 is formed toward a plasma generation space S and serves as a facing electrode facing an electrode 7 within a mounting table 5 with the plasma generation space S therebetween. A ratio of a surface area of the facing electrode with respect to that of an electrode for bias (facing electrode surface area/bias electrode area) is in a range of from about 1 to about 5.

Provided is a method of manufacturing a battery having an electrode module including: a positive plate having a cathode collector portion formed by attaching a lead member to a cathode substrate made of a foamed metal plate; and a cathode collector plate welded to the cathode collector portion. The method includes: a pre-welding positive plate forming process of forming a pre-welding positive plate, which is the positive plate before welding, such that the pre-welding positive plate has a projection projecting from a pre-welding cathode collector portion, which is the cathode collector portion before welding; and a welding process of melting a pre-welding cathode collector plate to weld it to the projection. In the pre-welding positive plate forming process, the projection is formed into such a shape that the condition that S≦1.3W is satisfied, where W and S represent the width and the circumferential length of the projection, respectively.

A network system enables controlling an image input device without requiring a driver that depends on the computer environment. A client terminal has a component that acquires a web page having an embedded scanner control script that controls image input from a scanner; a component that sends an image acquisition request through an interface board to the scanner as controlled by the scanner control script; and a component that gets an image from the scanner as a response to the image acquisition request as controlled by the scanner control script. The interface board receives the image acquisition request, and sends the image scanned by the scanner based on the received image acquisition request to the client terminal.
