Abstract: An element module includes a cooler, a plurality of elements, and a conductive member. The cooler includes a first element disposition portion and a second element disposition portion which are provided on both sides in a predetermined direction. The plurality of elements are disposed in each of the first element disposition portion and the second element disposition portion. The conductive member is disposed in a space portion of the cooler. The space portion penetrates the cooler between the plurality of elements in each of the first element disposition portion and the second element disposition portion. The space portion allows the first element disposition portion and the second element disposition portion to communicate with each other. The conductive member is connected to the element of the first element disposition portion and the element of the second element disposition portion.

Abstract: To provide an electromagnetic wave radiation detection member, an electromagnetic wave radiation detection method, and a device including the electromagnetic wave radiation detection member that make it possible to determine whether an object to be detected has been heated by electromagnetic wave radiation by a microwave oven or the like. One embodiment includes a detection material 1 containing liquid and discoloring a substance to be attached to which the detection material adheres, and a bag 2 including the detection material 1 therein and from which the liquid flows out due to radiation of electromagnetic waves. Accordingly, the substance to be attached is discolored due to electromagnetic wave radiation, thereby making it possible to determine whether the electromagnetic waves have been radiated.

Abstract: A portable electronic device comprises a key input unit including a plurality of keys or buttons. A plurality of key backlight LEDs are arranged right below or close to predetermined keys or buttons of the plurality of keys or buttons. The key backlight LEDs are capable of selecting and setting a plurality of colors for light emission. A light emission control unit provides a notification of a state of the portable electronic device with a lighting pattern of the plurality of key backlight LEDs.

Abstract: Disclosed are an electromagnetic wave radiation detection member, an electromagnetic wave radiation detection method, and a device having the electromagnetic wave radiation detection member, which make it possible to determine whether or not the member has been heated by the electromagnetic wave radiation, such as a microwave oven. Specifically disclosed is an electromagnetic wave radiation detection member which is provided with a detection material (1) containing liquid and discoloring a substance to be adhered to which the detection material is adhered, and a bag (2) which includes the detection material (1) and from which the liquid flows out due to the radiation of the electromagnetic waves. As a result, the substance to be adhered is discolored by the electromagnetic wave radiation, thus making it possible to determine whether or not the electromagnetic waves have been radiated.

Abstract: A short-arc type high pressure discharge lamp in which durability is improved and a lamp apparatus including the same is provided. Glass material portions 52A into which glass material enters respectively are provided on both sides of an electrode axis 5402 between the outer circumferential surface 5406 thereof and a curved portion 58 of a sealed metal foil 56, and a gap S3 being continuous with a sealed space 60 remains among the glass material portion 52A, the outer circumferential portion 5406 of the electrode axis 5402, and the curved portion 58. An angle formed by a surface 52-1 of the glass material portion 52A facing the gap S3 and the curved portion 58 is an obtuse angle ?. In other words, an angle formed by the surface 52-1 of the glass material portion 52A facing the gap S3 and a surface 5602 of the curved portion 58 of the sealed metal foil 56 is the obtuse angle ?.

Abstract: An indexable insert for application to turning of a cast iron product, including a first minor cutting edge 21 having a radius Ra and a second minor cutting edge 22 having a radius Rb successively provided between an arcuate nose cutting-edge 12 having a nose radius R and a linear cutting edge 16 so as to extend from the nose tip to the linear cutting edge 16. At a connection point P1 between the arcs assumed by the cutting edges 12 and 21, a smaller intersectional angle &thgr;x of a tangent T12 and a tangent T21 to the respective arcs is 1° or less. Also, at a connection point P2 between the arcs assumed by the cutting edges 21 and 22, a smaller intersectional angle &thgr;y of the tangent T21 and a tangent T22 to the respective arcs is 1° or less. The radii R, Ra, and Rb are set to the dimensional relationships “Ra>R, Ra falls within a range of 3 mm to 20 mm, and Rb≧1.5Ra.
