摘要:
A coil failure detection circuit detects a rise of a collector current of an IGBT and a timer circuit measures the length of a rise period. If the rise is not a normal one, an electronic control unit judges that a coil failure has occurred. The electronic control unit turns off the IGBT to prevent misfires and stops a flow of fuel gas to a combustion chamber to prevent melting or deterioration of a catalyst.

A location system comprises a communication terminal for transmitting a location request specifying a target mobile terminal and a type of location information, and a location network. In response to the location request, the location network produces current location information of the target mobile terminal if the type of location information of the received request specifies current location information and transmits the current location information to the communication terminal and stores the last known location information in a memory as last known location information of the target mobile terminal. If the type of location information specifies last known location information, stored last known location information of the target mobile terminal is copied from the memory and transmitted to the communication terminal if the location request is verified by a privacy check and if the stored information is reusable.
摘要:
A control device has a coupling determination sensor for detecting external connection of a charge table. When the connection of the charge cable is detected according to a signal from the sensor, the control device activates an electric device connected to a communication line of a charge-time-dedicated power supply system. Since the control device of the invention can activate only the electric device related to the charging while keeping electric devices not related to the charging at rest, and therefore prevents wasteful electric power consumption.

The speech estimation system of the present invention includes a transmitter (2) for transmitting a test signal, a receiver (3) for receiving the test signal, and a speech estimation unit (4) for estimating speech from a received signal. Transmitter (2) transmits the test signal toward speech organs, receiver (3) receives the test signal that has been reflected by the speech organs, and speech estimation unit (4) estimates speech or speech waveforms based on the waveform of the reflection wave of the test signal that was received by the receiver (3).

A dual-gate field effect transistor includes a substrate 1, a source 7-1, a drain 7-2, a vertical channel 5 provided between the source and the drain as rising from the substrate, a pair of gate insulation films 6-1 and 6-2 sandwiching the channel from a direction orthogonal to a carrier-running direction in the channel and a pair of gate electrodes 3-1 and 3-2 facing the vertical channel 5, respectively, via the pair of gate insulation films 6-1 and 6-2, wherein the pair of insulation films have different thicknesses t1 and t2. It is also possible that the pair of gate insulation films 6-1 and 6-2 have different permittivities ε1 and ε2 and that the pair of gate electrodes have different work functions Φ1 and Φ2. Thus, it is possible to set the threshold voltage of the dual-gate field effect transistor to a desired value when fabricating it. Furthermore, it is possible to avoid the problem of an increase in subthreshold slope that occurs in the prior art.

A radio communication apparatus in a radio packet communication system constituted by a plurality of radio stations and having a plurality of radio channels is provided. To allow radio stations belonging to different radio links to directly communicate with each other, when a packet as data is to be transmitted, a channel control section (101) inquires of a channel registration section (102) about a radio channel used for reception by a radio station corresponding to the destination address in input transmission data, and a radio channel used for packet transmission is selected. The packet is then transmitted from a transmission/reception section (103) via the selected radio channel. When a packet is to be received, the radio channel in the transmission/reception section (103) is switched to the self-station radio channel stored in a self-station channel storage section (104).
摘要:
In each cell of a plurality of cells of a mobile communication network assigned with a predetermined number of radio channels, a base station allocates to a call one of the radio channels according to autonomous channel reuse partitioning as a communication channel on transmitting messages to and from a mobile unit which is currently present alive in the cell under consideration. For use as the communication channel, the radio channel should preferably have a base and a mobile carrier to interference ratio which is equal to or greater than a first allocation threshold level determined by a sum of a power control margin for base and mobile transmission powers and a second allocation threshold level determined to be sufficient for transmission of the messages. If such a radio channel is not available, another of the radio channels is used as the communication channel that has the base and the mobile carrier to interference ratios both equal to or greater than the second allocation threshold level. It is thereby rendered possible to control the mobile transmission power after allocation of the communication channel and furthermore the base transmission power.

摘要:
A two-dimensional pattern of a silicon oxide film is formed on a silicon surface of a substrate, thereby to form a material, the two-dimensional pattern being represented by the presence and absence and/or thickness variations of the silicon oxide film. The material is nitrided to form a modified layer on the surface of the material, the modified layer being thicker on the silicon oxide film and thinner on the silicon surface of the substrate or thicker on the thicker portion of the silicon oxide film and thinner on the thinner portion of the silicon oxide film. The thinner portion of the modified layer is removed while leaving the thicker portion of the modified layer, for thereby forming the modified layer on the silicon oxide film substantially in the same shape as the silicon oxide film. An oxidant diffusion prevention film is formed at least on a thicker portion of the oxide film which has a thicker portion and a thinner portion on a substrate, then a silicon film, a silicide film, or a multilayer film composed of silicon and silicide films is deposited on a surface of the substrate a mask layer is formed on the film or films. The silicon film, the silicide film, or the multilayer film is oxidized to pattern the same in a shape corresponding to the mask layer. A relatively thin silicon oxide film may be formed on the oxidant diffusion prevention film.
