A ceramic heater 1 includes a rodlike heater body 2 configured such that a ceramic resistor 10 is embedded in a ceramic substrate 13. The ceramic resistor 10 includes a front end part 11a and two large-diameter rodlike portions Ld. The large-diameter rodlike portions Ld form passages for supplying electricity to the front end part 11a, extend rearward along a direction of an axis O of the heater body 2, and have an electricity-supply sectional area greater than that of the front end part 11a. The large-diameter rodlike portions Ld each have a connection end part connected to the front end part 11a. The connection end part is formed of a first electrically conductive ceramic and constitutes a first resistor portion 11. The remaining portion of each of the large-diameter rodlike portions Ld is formed of a second electrically conductive ceramic having an electrical resistivity lower than that of the first electrically conductive ceramic and constitutes a second resistor portion 12. A joint interface 15 between the first resistor portion 1 and the second resistor portion 12 is located within the corresponding large-diameter rodlike portions Ld.

A ceramic heater 1 is configured such that a ceramic resistor 10 includes a first resistor portion 11, which is disposed at a front end portion of a heater body 2, and which is formed of a first electrically conductive ceramic, and a pair of second resistor portions 12, which are disposed on the rear side of the first resistor portion 11 so as to extend along the direction of the axis O of the heater body 2. The front end parts of the second resistor portions 12 are joined to corresponding end parts of the first resistor portion 11 as viewed along the direction of electricity supply. The second resistor portions are formed of a second electrically conductive ceramic having an electrical resistivity that is lower than that of the first electrically conductive ceramic. At least a portion of a joint interface 15 between the first resistor portion 11 and each of the second resistor portions 12 deviates from a transverse plane P that perpendicularly intersects the axis O of the heater body 2. The joint interface 15 is formed of planes that perpendicularly intersect a reference plane K including the respective axes J of the second resistor portions 12.

A glow plug according to one embodiment of the present invention includes a cylindrical metallic shell, an electrode rod disposed in a rear portion of the metallic shell, a heater disposed in a front portion of the metallic shell, and an electric insulator provided between an inner surface of the metallic shell and a circumferential surface of the electrode rod to keep the electrode rod insulated from the metallic shell. The metallic shell has a portion caulked to the electrode rod at a location axially corresponding to the electric insulator so that the circumferential surface of the electrode rod becomes deformed to define therein a recessed portion. The caulked portion is engaged in the recessed portion with the caulked portion with the electric insulator interposed between the caulked portion and the recessed portion, thereby securing the electrode rod in the metallic shell.

A fuel cell includes a pair of interconnectors (ICs); a cell main body provided between the ICs and including an electrolyte, a cathode and an anode formed on respective surfaces of the electrolyte; and a current collection member provided between at least one of the cathode and the anode and the IC for electrically connecting the cathode and/or the anode and the IC. The current collection member has a connector abutment portion which abuts the IC, a cell main body abutment portion abutting the cell main body, and a connection portion connecting the connector abutment portion and the cell main body abutment portion, the portions being continuously formed. Between the cell main body and the IC, a spacer is provided so as to separate the connector abutment portion and the cell main body abutment portion.

Provided is an information distribution system (100), in which a control section (4) deletes, when a member registration cancellation of a distribution service is instructed by an input unit (1d) of a vehicle-mounted device (10), the contents information and the uplink information stored in a storage unit (1f), other than the fundamental information, thereby to set ON a member registration cancellation flag. If the member registration cancellation flag is set ON when the communication with a center apparatus (30) is established, moreover, the control section (4) writes a code indicating the member registration cancellation, in the fundamental information of the uplink information, and transmits the same to the center apparatus (30). When this center apparatus (30) receives the uplink information from the vehicle-mounted device (10), the center apparatus (30) decides whether or not the code indicating the member registration cancellation is contained in the fundamental information. If the center apparatus (30) decides that the code is contained, the center apparatus (30) deletes, from a member information DB (341), the member registration information of the record having the vehicle-mounted device ID of the sender vehicle-mounted device (10). As a result, it is possible to cancel the member registration of the distribution service of the content information in the vehicle-mounted device.
摘要:
A temperature sensor element 10 has a reduced thermal conduction path from a measurement object to a sensitive end portion 22 of a thermocouple 21 and a high-dense insulating ceramic base body 20. Since the temperature sensor element 10 has excellent thermal conductivity from the measurement object to the sensitive end portion 22 of the thermocouple 21, it is also excellent in responsiveness at the time of temperature detection. Further, corrosion and material deterioration of the thermocouple 21 is unlikely to occur because the thermocouple 21 does not directly contact the measurement object (exhaust gas). As a result, the temperature sensor element 10 exhibits excellent durability. Therefore, the temperature sensor element 10 exhibits a good responsiveness at the time of temperature detection as well as excellent durability.

Reproduction is performed so that the user can grasp the details of content information on long sentence reading the reproduction of which has been suspended. If an vehicle-mounted device (10) receives content information with higher priority of the reproduction than that of the content information on the long sentence reading during the reproduction of the content information on the long sentence reading received from a center apparatus by a reproduction section (step S4; Y), the vehicle-mounted device (10) allows the control of a control unit to suspend the reproduction of the content information on the long sentence reading (step S7) and to start the reproduction of the content information with higher priority (step S8). If the reproduction ends, the vehicle-mounted device (10) allows the reproduction means to resume the suspended reproduction of the content information on the long sentence reading (step S12).
