  • Patent number: 10354867
    Abstract: A method for manufacturing an epitaxial wafer comprising a silicon carbide substrate and a silicon carbide voltage-blocking-layer, the method includes: epitaxially growing a buffer layer on the substrate, doping a main dopant for determining a conductivity type of the buffer layer and doping an auxiliary dopant for capturing minority carriers in the buffer layer at a doping concentration less than the doping concentration of the main dopant, so that the buffer layer enhances capturing and extinction of the minority carriers, the minority carriers flowing in a direction from the voltage-blocking-layer to the substrate, so that the buffer layer has a lower resistivity than the voltage-blocking-layer, and so that the buffer layer includes silicon carbide as a main component; and epitaxially growing the voltage-blocking-layer on the buffer layer.

    Abstract: An electrostatic capacitance type input device includes: first electrodes arranged in a first direction and extending in a second direction intersecting the first direction; second electrodes arranged in the second direction and extending in the first direction; a storage unit storing first direction detection values obtained through the first electrodes resulting from the change in capacitance between a first conductor and the electrodes, and storing second direction detection values obtained through the second electrodes resulting from the change in capacitance between the first conductor and the electrodes; and a calculation unit, which generates first map values from a first value and a second value obtained, respectively, by processing at least one of the first direction detection values and at least one of the second direction detection values. The calculation unit determines whether the first conductor has approached the first electrodes and second electrodes using the first map values.

  • Publication number: 20120289127
    Abstract: A spherical core type lens grinding device (1) performs an operation wherein a dish-shaped grindstone (8) provided with a spherical grindstone surface (8a) which is equipped with diamond abrasive grains, is pressed against a surface-to-be-ground (7a) of a lens blank (7) to be ground, and wherein the dish-shaped grindstone (8) is rotated and is simultaneously swung, resulting in said surface-to-be-ground (7a) being ground to a spherical surface. In an initial-stage grinding process, grinding is performed at first processing pressure and first rotational speed. In an intermediate-stage grinding process, grinding is performed at second processing pressure and second rotational speed. In a last-stage grinding process, grinding is performed at third processing pressure and third rotational speed. The second processing pressure is a pressure at which the spherical grindstone surface (8a) can bite into the lens blank (7).

  • Patent number: 7406401
    Abstract: A sensor network controller (4) includes: a sensor interface (44) receiving sensing data transmitted from sensors (5); a data write section (150) writing the received sensing data and sensing time information indicating a sensing time of the sensing data in association with each other to a memory section (42); the memory section (42) storing the sensing data and the sensing time information; a first data processing section (144) generating sensing data which is at the timing designated by a client on the basis of the sensing data and the sensing time information stored in the memory section (42); and a data output section (148) outputting the generated sensing data to the client. The client is enabled to acquire sensing data in accordance with a request even if the scheme by which the sensors convey sensing data does not match with the scheme by which the client makes a request for sensing data.

  • Patent number: 7109875
    Abstract: In a sensor network system, a communications network connects a set of sensors to a server collectively managing the set of sensors. First, the sensor-managing server acquires remaining drive times of batteries in the sensors, and specifies a target remaining drive time. The server then controls the operation of the sensors so that the remaining drive times of the batteries in the sensors are substantially equal to the target remaining drive time. This reduces the maintenance workload for a system manager, especially, in the recharging of the sensor batteries.

  • Patent number: 7102535
    Abstract: A mobile communication device (3) can be disconnected form a vehicle monitoring apparatus (1) arranged on vehicle for sensing the state of the vehicle as a monitoring object and transmitting sensing data representing the sensing result. The mobile communication device (3) can also be connected via a communication network (4) to a report destination. The mobile communication device (3) includes a judgment unit (41a) for judging the state of the vehicle according to the sensing data, a decision unit (41b) for deciding a report destination to be connected according to the judgment result of the judgment unit (41a), and a communication unit (42) for receiving the sensing data and establishing a connection with the report destination decided by the decision unit (41b). Thus, it is possible to report the abnormal state of the vehicle sensed to an appropriate report destination in a short time.

  • Patent number: 7095332
    Abstract: An alarm device including a sensor having sufficiently high detection sensitivity. The sensor 51 in the alarm device 41 is disposed such that a plane M perpendicular to the detection direction P of the sensor 51 is aligned at a specified angle ? with respect to a plane V perpendicular to the sun visor 72 (the lower surface 61a), were the specified angle ? should be set to be an approximately mean value of the expected minimum angle ?=0° and the expected maximum angle ?=40° (in this case, ?=20°). In other words, the plane M perpendicular to the detection direction P of the sensor 51 should be aligned at an angle ?(?=90°??) of less than 90° with respect to the sun visor 72 (the lower surface 61a). The alarm device may be mounted onto a vehicle for preventing the vehicle theft.
