摘要:
The present high-frequency distribution circuit includes a switch circuit which passes a high-frequency signal from the other terminal of a high-frequency line to an output terminal if a receiver is connected to the output terminal and which grounds the other terminal of the high-frequency line via a terminator resistor if the receiver is not connected to the output terminal. As seen at an input terminal toward the output terminal, a constant value in resistance is provided regardless of whether the output terminal is used or not.

A fluid circuit module controls a fluid to be supplied to a movable element in an automatic transmission. The fluid circuit module is provided with a first body in which a first flow passage is formed, a second body in which a second flow passage is formed. A separation plate is set between the first body and the second body and has a deformation portion that is deformed and strained in accordance with the difference between pressures in the first flow passage and the second flow passage. A strain sensor is attached to the deformation portion for detecting a strain of the deformation portion. A control means controls a supply fluid to be supplied to the movable element on the basis of a detection result of the strain sensor.

The semiconductor device comprises a collector layer 14; a base layer 16 of a carbon-doped GaxIn1-xAsySb1-y layer having one surface connected to the collector layer 14; an emitter layer 18 connected the other surface of the base layer 16; a base contact layer 30 of a carbon-doped GaAsSb layer electrically connected to the base layer 16; and a base electrode 32 formed on the base contact layer 30. The semiconductor device of such structure can have a much reduced base resistance RB, whereby InP/GaInAsSb-based HBTs including InP/InGaAs-based HBTs can have higher maximum oscillation frequency fmax. Because of the carbon-doped semiconductor layer the semiconductor device can have higher reliability.

摘要:
Since both a physical storage place and a logical storage place in a storage system are separately managed as a directory structure, or a hierarchical structure, even in such a case that the physical storage place has been changed, the logical storage place which is displayed to the user is not changed, and thus, the user can use the file while the user need not become aware of the change of the file. When the contents of a file is displayed, a physical storage destination of the file is acquired based upon both a reference path and a relative path of the file, and then, the file is acquired from the physical storage destination.
