Provided is a single crystal with a hexagonal wurtzite structure which is useful as a substrate for various devices and has high purity and is uniform. The single crystal with a hexagonal wurtzite structures which is obtained by a crystal growth on at least an m-plane of a columnar seed crystal and represented by AX (A representing an electropositive element and X representing an electronegative element) is characterized in that a variation in the concentration of a metal other than the electropositive element A and having a concentration of 0.1 to 50 ppm is within 100%.
摘要:
A structure of a wireless communication device for calling an emergency report center via a cellular phone network is simplified. Further, provision is made so that voice communication can be established with the emergency report center from anywhere. To provide such an advantage, a built-in wireless communication section is used to transmit data, including a phone number of a cellular phone possessed by a user in a vehicle when an emergency report is made to the emergency report center via the cellular phone network. An operator in the emergency report center uses the phone number of the cellular phone to establish voice communication with the user. Since the built-in wireless communication section does not require a voice communication circuit, the wireless communication device structure can be simplified to reduce a size and cost of the device. Further, the emergency report center can establish voice communication with the user even when the user has to stay away from the vehicle depending on a situation.
摘要:
An ordinary telephone communication circuit is provided in addition to the emergency informing circuit in an emergency informing apparatus. In the non-emergency condition, ordinary telephone communication is provided through a wireless communication network. In the emergency condition, the emergency data is transmitted to a predetermined station through the wireless communication network. An interface for transmitting and receiving data is further provided. A data converter for converting data may be provided as a data communication adapter. An automatic dialing circuit may be provided. An emergency informing system including the emergency informing apparatus, the wireless network, and a terminal of a predetermined station for receiving the emergency data from the emergency informing apparatus is also disclosed.
摘要:
An emergency communication system is installed on a vehicle for transmitting emergency information such as traffic accident, sudden illness, etc. to a center such as police station. It is used for the purpose of preventing inadvertent neglect of the connection of a handy phone to the system terminal unit when the handy phone is used as the emergency communication conveying means. In case it is not connected normally, a signal is set to a vehicle starting system 4 to prohibit the starting operation of the vehicle. This information is displayed on LED or LCD on a dashboard of the vehicle by the information transmitting means 6, and it is further stored in a storage unit 15 so that it can be picked up from outside via an external equipment connection interface 7.
摘要:
An emergency reporting apparatus for a vehicle includes a microphone, a loudspeaker, and a handsfree system circuit. Handsfree two-way speech communication with an emergency report receiving center is allowed via the microphone, the loudspeaker, and the handsfree system circuit. A volume control circuit connected to the loudspeaker operates for controlling a volume level of sound generated by the loudspeaker at a predetermined constant level or higher. The volume control circuit may control the volume level at the predetermined constant level, and may inhibit a user from changing the volume level.
摘要:
If a user wants to store an image acquired from a site and it is determined that the data size of the image acquired from the site is larger than a designated storage frame in a memory region, then it is determined whether or not the number of colors in the pallet of the acquired image data can be reduced. Next, if the number of pallet colors can be reduced, the number of pallet colors is reduced to thereby compress the pallet and the image data is updated based on the compressed pallet. On the other hand, if it is determined that the number of pallet colors cannot be reduced, a control section determines that the image data cannot be registered or stored and abandons the data and a display section displays storage error.
摘要:
A wireless communication circuit provides wireless communication with a network; and a supply power control circuit controls supplying a power to at least one of said wireless communication circuit and a unit in a vehicle in response to a command signal which is inputted from an operation circuit or through the wireless communication circuit. The power is periodically supplied to a unit in its vehicle or the wireless communication circuit. A control circuit receives data from the unit and stores the data. The data is outputted or transmitted in response a data request. The unit may be a position detection circuit including a GSP receiver. The power is cut off when the unit is not used. Information is transmitted to the vehicle terminal apparatus which stores and displays it in response to a data command or a start-up of the vehicle. A diagnostic function may be provided. The main battery may be checked and the result is transmitted. The position of the vehicle are periodically detected and compared to detect a trouble of the vehicle. The result may be transmitted. An emergency informing function or system may be provided. The information transmitting system reads data from a data base and transmits data to a vehicle terminal apparatus.
摘要:
A main controller for controlling an emergency informing terminal, and a sub controller for controlling communications with an external device are provided. The main controller and sub controller have microcomputers, and the main controller and sub controller monitor the operation of each other. If the other is abnormal, a reset signal is issued to initialize it, and if still abnormal, the history of abnormality is recorded, and the abnormality is informed to the user by means of sound or light. The power source device of this emergency informing terminal has a function of cutting off power supply to the emergency informing terminal when overheat or overcurrent occurs in the auxiliary battery which operate when supply from the main battery is interrupted, and if overheat or voltage drop occurs due to short circuit of the auxiliary battery or other trouble, power supply into the emergency informing terminal is cut off, so that spread of damage may be avoided.
摘要:
The disclosed emergency informing terminal mounted on a vehicle for making an emergency call to the center for supervising the emergency informing system recognizes emergency informing signals of different signal formats, and executes the emergency informing process. This emergency informing terminal recognizes emergency informing signals entered in different signal formats in every vehicle, and the control unit for executing emergency informing process according to the signal recognizes whether the signal format belongs to the air bag equipment connected to a vehicular LAN or the directly connected air bag equipment on the basis of the status signal. Consequently, transferring to the input state confirming state of the signal format, the signal is processed. Further, when a signal showing air bag developing state or the like is entered, the emergency informing process is started.
