A mining riser pipe is extended from above water toward a water bottom containing water bottom resources, and a lower portion of an insertion pipe connected to a lower portion of the mining riser pipe is inserted into the water bottom. A liquid is supplied into the insertion pipe and a rotation shaft extends axially inside both of pipes is rotated to rotate stirring blades attached to a lower portion of the rotation shaft inside the insertion pipe, thereby drilling and dissolving mud S inside the insertion pipe into a slurry form by is raised to an upper portion of the insertion pipe by a stirring flow generated by the rotation of the stirring blades, and the raised mud is lifted above the water through the mining riser pipe by a lifting force.

Water bottom resource collecting system and collecting method

An apparatus detects a plurality of areas from an overall image, determines on each of the plurality of areas whether the area is a candidate for an area including an object as a processing target based on a determination reference value (first determination processing), acquires a zoom-in image of the area determined to be the candidate for the area including the object in the first determination processing, and determines whether the acquired zoom-in image is an image of the object (second determination processing). The apparatus identifies an area, in the overall image, corresponding to the zoom-in image determined not to be the image of the object in the second determination processing, and performs control to update the determination reference value used in the first determination processing based on image information of the identified area in the overall image.

Image processing apparatus, control method of image processing apparatus, and storage medium

A control apparatus includes a receiving unit that receives a captured image obtained by capturing an image in an optical finder of an image capture device in a state in which AF frames are displayed on the optical finder, a display unit that displays the captured image and a UI (user interface) for selecting at least one AF frame from AF frames displayed on the captured image, and a transmitting unit that transmits, to the image capture device, information for specifying the at least one AF frame selected via the UI.

A high pressure discharge lamp can be used in a vehicle lighting device as a light source in place of a halogen lamp, and can be driven with a reduced starting voltage while being miniaturized. A gas is filled in a space between an arc tube and an outer tube of the high pressure discharge lamp, the gas being capable of dielectric barrier discharge, to reduce the starting voltage. A metal conductor is arranged in the space between the arc tube and the outer tube to stabilize the starting voltage and perform other functions. The metal conductor can also serve as a lead line. Accordingly, high voltage portions of the lamp are not exposed outside of the outer tube. This can reduce the entire size of the high pressure discharge lamp such that a housing for a headlight using a halogen lamp can be used for this type of high pressure discharge lamp.

High pressure discharge lamp

A vehicle light that includes a semiconductor light emitting device can have a simple structure which suppresses deterioration of the light emitting quality of the device. The vehicle light can be configured to prevent aging and/or deterioration of components, such as a vapor deposited silver coating on the reflection surface of a reflector of the light. The vehicle light can also include a projector type optical unit that has the following components: a semiconductor light emitting device; a reflector which surrounds the semiconductor light emitting device from a rear side such that light emitted from the semiconductor light emitting device is reflected in a forward direction; and a projection lens which projects light being directly from the light emitting device or after reflected by the reflector in the forward direction. Furthermore, a space around the semiconductor light emitting device of the optical unit can be hermetically sealed from the outside atmosphere. A sealing member can be used to form the sealed space.

In a metal halide lamp, xenon gas having a pressure of at least 3 atmospheres at room temperature and at least a metal halide including indium iodide are sealed in a discharge space not containing mercury. If the volume of the discharge space is denoted by V (mm), the electric power applied to the arc tube by P (W), and the weight of the indium iodide by X (&#x3bc;g), these parameters are set so as to satisfy a relationship (P/V)(X/V)&#x3e;3.0. A continuous emission spectrum can thereby be produced by indium over the entire visible wavelength range, thus obtaining a mercury-free metal halide lamp that is usable as an excellent white light source suitable for data projectors, automobile lamps, headlights, and other systems and devices.
