A multilayer dielectric substrate includes a first signal via, a second signal via, an internal-layer signal line, an internal-layer ground conductor, and ground vias. The first signal via is connected to a bias-and-control-signal terminal of a high-frequency semiconductor, and is arranged within a region corresponding to the electromagnetic shielding members. The second signal via is arranged outside the region, and is connected to an external terminal for a bias and control signal. The internal-layer signal line connects between the first and the second signal vias. The internal-layer ground conductor is arranged around the first and the second signal vias and the internal-layer signal line. The ground vias are arranged around the first and the second signal vias and the internal-layer signal line, on the internal-layer ground conductor. A resistance film is provided on at least one of an upper surface and a lower surface of the internal-layer signal line.

A wireless communication device, an individual information writing device, and an individual information setting method that efficiently write individual information, such as a unique identifier used for wireless communication, to each wireless device. An address writing device transmits a unique address setting communication request. A wireless device has a control unit that checks whether a provisional address is set in a unique address memory. When a provisional address is set, the control unit measures the signal intensity of a received unique address setting communication request with an electric field intensity measuring unit. When the electric field intensity is greater than a threshold value stored in an address setting condition memory and thereby satisfies an address setting condition, the wireless device performs a process for setting a unique address and then transmits a completion notification to the address writing device.

Heretofore, a plurality of packages were used in a high frequency module in which a plurality of waveguide terminals were positioned resulting in problems, such as degradation of characteristics in the connection lines between packages, lower ease of assembly when mounting and connecting the connection lines, increased cost, and so forth. To solve these problems, a plurality of cavities having a part or the entire side metallized is formed in a multi-layer dielectric substrate. The multi-layer dielectric substrate is provided with a plurality of waveguide terminals, microstrip line-waveguide converters, RF lines, bias and control signal wiring, and bias and control signal pads. A high frequency circuit is mounted within the cavity and sealed with a seal and cover. This is intended to reduce the number of package, improve performance, improve fabrication, and lower the cost.

A speed change gear system of the planetary type suited for applications to fluid couplings utilized upon automotive vehicles includes at least first, second, and third planetary gear sets suitably interposed between an input shaft and an output shaft, first and second clutches, and first, second, and third braking means. The first planetary gear set may include a first sun gear, a first planetary gear engaged therewith, a second planetary gear engaged with the first planetary gear, a first ring gear enmeshed with the second planetary gear, and a first carrier rotatably supporting the first and second planetary gears, while the second planetary gear set may include a second sun gear drivingly coupled to the first carrier, a third planetary gear engaged with the second sun gear, a second ring enmeshed with the third planetary gear, and a second carrier rotatably supporting the third planetary gear, and the third planetary gear set may include a third sun gear drivingly coupled to the first sun gear and the second ring gear, a fourth planetary gear interengaged with the third sun gear, a third ring gear enmeshed with the fourth planetary gear, and a third carrier rotatably supporting the fourth planetary gear and drivingly coupled to the second carrier and to the output shaft. The first clutch couples or uncouples the input shaft to or from the first sun gear, the second ring gear and the third sun gear, while the second clutch couples or uncouples the input shaft to or from the first carrier and the second sun gear. The first brake is capable of locking the first carrier and the second sun gear to the gear casing while the second brake is capable of locking the first ring gear to the casing and the third brake is capable of locking the third ring gear to the casing.
