A contact detecting device includes a plurality of detecting elements, a generating unit, and a determining unit. The plurality of detecting elements are related to one another in a two-dimensional configuration on a predetermined contacted surface, and respectively detect a contact of an object with the contacted surface. The generating unit generates, on the basis of the result of detection by the plurality of detecting elements, feature information representing a feature of a trajectory drawn on the basis of a contact of an object with the contacted surface. The determining unit determines whether or not the feature information generated by the generating unit corresponds to previously registered specific contact feature information representing a feature of a trajectory drawn on the basis of a specific contact of an object with the contacted surface.

A vibration damping structure for a steering wheel includes an airbag mounted in the steering wheel, an inflator arranged forward of the airbag, and a support member elastically supporting the inflator at a position forward of the inflator. The inflator includes a peripheral wall portion and gas ports formed in the wall portion. The support member has a hole facing the inflator. A sealing portion is provided to surround the hole. Through contact between the inflator and the support member at the sealing portion, gas leakage via the hole is prevented. The inflator has a pressure receiving portion in the vicinity of the gas ports to change the flow direction of gas, which is discharged outward from the gas ports in the radial direction of the wall portion, to a direction toward a rear side. The pressure receiving portion produces force acting forward by receiving pressure from the gas.
摘要:
A handwriting detection sheet includes a handwriting layer, a code layer and an optical layer. The handwriting layer can display handwriting. The code layer is placed on a rear-face side of the handwriting layer. The code layer includes plural code images arranged in a matrix manner. In the code images, position codes are encoded with a light absorption material that absorbs infrared light. The optical layer is placed on a rear-face side of the code layer. The optical layer reflects infrared light and allows visible light to pass through.

An object of the present invention is to provide a solid scintillator having short afterglow and high output, and a radiation detector and a tomograph using the solid scintillator. A solid scintillator according to the present invention is a solid scintillator comprising a polycrystal containing a crystal of a Gd garnet structure oxide having a composition ratio represented by the following formula (1): [Formula 1] (M1-x-yGdxQy)3J5O12 (1) wherein M is at least one element of La and Tb, Q is at least one element of Ce and Pr, J is at least one element selected from Al, Ga, and In, x and y satisfy relations 0.5≦x≦1, and 0.000001≦y≦0.2, and further containing Si and fluorine, wherein the solid scintillator contains 1 ppm by mass to 1000 ppm by mass of the Si with respect to the Gd garnet structure oxide, and 1 ppm by mass to 100 ppm by mass of the fluorine with respect to the Gd garnet structure oxide.
摘要:
A medium writing apparatus obtains information to be written onto a recording medium, converts the information into a suitable writable format, and then writes the converted information onto the recording medium. An ID obtaining section obtains a medium ID from the recording medium, or through an input by the user. The medium ID and information indicating the place of the written information are sent to a server, and then stored as index information correlating them with each other. When the information written onto the recording medium is to be used at a later timing, the medium ID is identified, and the index information is obtained from the server. Therefore, the original information can be obtained so as to be easily reprocessed or reused.
