Abstract: A wavelength conversion member is provided which includes a phosphor layer having an increased pencil hardness and thereby has a reduced risk of breakage such as scattering of fragments of the phosphor layer or separation of the phosphor layer.A substrate 12 is made of sapphire, and a phosphor layer 14 is disposed on the substrate 12 and includes phosphor particles 16 and a light transmissive inorganic material 22. The phosphor layer 14 has a pencil hardness of 5B or above. The high hardness of the phosphor layer 14 reduces the risk of breakage such as the phosphor layer 14 being scattered as fragments or being separated from the substrate 12.

Abstract: A wiring board includes recesses recessed to an inside of the wiring board, in a plan view, in portions connecting a far end surface to side surfaces, and an outer peripheral electroconductive layer disposed over a surface extending from the far end surface to the recesses. To electrically connect an electroconductive member to the outer peripheral electroconductive layer of the wiring board by, for example, joining such as soldering, the electroconductive member can be disposed in the recesses to be connected to the outer peripheral electroconductive layer. This structure prevents the electroconductive member from excessively protruding outward from the surface of the wiring board. Thus, a device having the wiring board installed therein can be made compact.

Abstract: A spark plug comprising: a first electrode including a tip containing Ir as a main material, and a base member to which the tip is joined; and a second electrode opposed to the tip with a spark gap therebetween. The number of crystal grains appearing in a range of 0.25 mm2 on an arbitrary cross-section of the tip in a first direction connecting the tip and the second electrode within the spark gap, is not less than 20. When a length of each of the crystal grains in the first direction is denoted by Y, and a length of each of the crystal grains in a second direction perpendicular to the first direction is denoted by X, 5 μm≤X≤100 μm and Y/X≥1.5 are satisfied.

Abstract: A particulate detection apparatus for controlling a particulate sensor detecting an amount of particulates in exhaust gas and including a calculation section, cumulating section, and anomaly determination section. The calculation section is configured to calculate, every time a previously set unit measurement time elapses, the value of a signal current or converted value representing the amount of electrified particulates. The cumulating section is configured to cumulate the value of the signal current or converted value thereof to thereby calculate a cumulative value. The anomaly determination section is configured to determine whether or not an amount of change in the cumulative value in a unit cumulating time set to be longer than the unit measurement time is greater than a previously set anomaly determination value, and to determine that the detection performance of the detection section is anomalous when the amount of change is greater than the anomaly determination value.

Abstract: A particulate sensor (1) having a sensor-side positioning portion (11k) for determining the circumferential position of a sensor main body (5) with respect to a sensor attachment portion (120) when the particulate sensor (1) is attached to the sensor attachment portion (120). The sensor attachment portion (120) has a pipe-side positioning portion (121) which conforms to the sensor-side positioning portion (11k) and is configured such that, when the particulate sensor (1) is attached to the sensor attachment portion (120), the circumferential position of the sensor main body (5) with respect to the sensor attachment portion (120) is always set to a fixed circumferential position.

Abstract: A spark plug including a center electrode with a tip welded to a front end portion with a fused portion therebetween. The front end portion contains Ni, Cr, and at least one element selected from a group B consisting of Mn, Si, Al, Ti, rare earth elements, Hf, and Zr. Ni is present in the largest proportion, and Cr is present in the second largest proportion and in an amount of 12% by mass or more. The at least one element selected from the group B is present in a total amount of 0.1% by mass or more. The front end portion satisfies f/e≤0.15 and m/e≤0.015, where f is the Fe content, e is the sum of the Cr, Si, and Al contents, and m is the Mo content.

Abstract: An electrochemical reaction cell stack includes an electrochemical reaction block including three or more electrochemical reaction units arranged in a first direction; a first heat-absorbing member which is disposed on one side of the electrochemical reaction block in the first direction and absorbs heat generated from the electrochemical reaction block; and a second heat-absorbing member which is disposed on the other side of the electrochemical reaction block in the first direction and absorbs heat generated from the electrochemical reaction block. An upstream electrochemical reaction unit is disposed between the first heat-absorbing member and the downstream electrochemical reaction unit disposed closest to the first heat-absorbing member, and an upstream electrochemical reaction unit is disposed between the second heat-absorbing member and the downstream electrochemical reaction unit disposed closest to the second heat-absorbing member.
