A spherical body polishing apparatus capable of reducing polishing costs includes a rotating disk having a rotating disk polishing surface and a fixed disk having a fixed disk polishing surface opposed to the rotating disk polishing surface. The rotating disk polishing surface is capable of relative rotation while keeping being opposed to the fixed disk polishing surface. The rotating disk polishing surface has a groove portion formed therein and extending circumferentially along the rotation. The rotating disk having the groove portion therein includes an abrasive grain layer having a higher hardness than that of a material ball which is a spherical body and a holding layer formed on the abrasive grain layer and having a lower hardness than that of the abrasive grain layer. The groove portion is formed to penetrate the holding layer in a depth direction and to reach the abrasive grain layer.

Thermal-type infrared imaging device comprises an infrared ray detection unit in which pixels, each of which includes a bolometer, are arranged two-dimensionally; and a signal processing unit that sequentially reads signal of each bolometer in synchronization with switching operation of a horizontal shift register and a vertical shift register, integrates the read signal using an integration circuit, and outputs the integrated signal. The signal processing unit is configured so that it can set a sensitivity (for example, voltage applied to bolometer, capacitance of a capacitor in the integration circuit, and/or period of time for integrating the signal) for each pixel according to a predetermined pattern in synchronization with switching operation for classifying a plurality of pixels into a plurality of types of pixels for which different sensitivities are set, for example, high-sensitivity pixels 15 with a narrow temperature measurement range and a high temperature resolution and low-sensitivity pixels 16 with a wider temperature measurement range and a lower temperature resolution than those of the high-sensitivity pixels 15.

A document data capturing device includes a sheet supply tray for carrying documents, a sheet discharge tray located below the sheet supply tray, and a document conveying mechanism including a conveying path along which documents are guided from the sheet supply tray to the sheet discharge tray. The document data capturing device includes a first data-capturing unit and a second data-capturing unit which scan respective sides of a document conveyed by the document conveying mechanism. The first data-capturing unit and the second data-capturing unit are each configured with a reduction-optics scanning mechanism. The conveying path along which a document to be scanned by the first and second scanning mechanisms is conveyed is formed to surround the second reduction-optics data-capturing unit. Thus, the device can be made compact.

A movable trailing edge is composed of a main body including a structural frame member in which a spar and a rib intersect with each other, and a first outer plate that covers the main body. The first outer plate is placed on and cover the structural frame member, a rotating probe is pressed against the first outer plate from the obverse side thereof to friction stir weld the first outer plate and the side end face of the structural frame member. Joint parts are arranged in a dotted pattern.

A navigation device includes a position detector, a controller, a display portion, an imaging portion and an image processor. The imaging portion images a forward view in front of the vehicle as a forward image from a predetermined distance before a guidance point. The image processor extracts and analyzes visual information of an on-road object from the forward image. The controller specifies a position of the on-road object based on the visual information and map information. The display portion displays and highlights an image of the on-road object at a true position in a road map image, when the position of the on-road object corresponds to the guidance point.
摘要:
An infrared detector having pixels which convert the infrared ray into an electric signal and are arranged to form a matrix. An infrared detecting unit is placed in a vessel having a shielding member for preventing the incident infrared radiated from the target object from being inputted to reference pixels. Only the infrared ray radiated from the shielding member is inputted to the reference pixels. The amount of infrared ray received by the reference pixels is supposed to equal the amount of infrared ray radiated from the inner wall of the vessel. The pixels other than the reference pixels receive the infrared ray both from the target object and the inner wall of the vessel. The circuit for reading out the electric signal generated by the pixels reads out the electric signal from the pixels using the electric signal from the reference pixels as a reference point.
摘要:
A frame 1 is formed of an outer chord 2 of T-shaped section having an extension 4 extending inwardly, and an inner chord 3 having a flat portion 5 abutting against the extension 4 of the outer chord 2. The extension 4 of the outer chord 2 and the flat portion 5 of the inner chord 3 are friction stir welded together with one abutted against the other.
