  • Publication number: 20200007124
    Abstract: An operation adjustment method of an SOI device comprises steps of: (a) obtaining a drain current-substrate bias voltage characteristic of an NMOS transistor for a source-gate voltage of 0V; (b) obtaining a lowest substrate bias voltage which turns on the NMOS transistor from the drain current-substrate bias voltage characteristic; (c) determining an upper limit of a substrate bias voltage of a PMOS transistor as a voltage obtained by subtracting a built-in potential of a pn junction from the lowest substrate bias voltage; and (d) determining the substrate bias voltage of the PMOS transistor as a positive voltage lower than the upper limit. Reduction in the power consumption and maintenance of the radiation tolerance are both achieved for the SOI device.

  • Patent number: 10501210
    Abstract: In an aerospace vehicle in which a satellite is detachably adapted to the first stage rocket and the second stage rocket, an electronic device 65 is installed in the satellite 60, wherein the electronic device 65 controls the first stage rocket 10 and the second stage rocket 20 before the satellite is detached from the first stage rocket 10 and the second stage rocket 20. Thereby, it is unnecessary to provide sensors, radio devices and electronic devices for exclusive use with respect to the first stage rocket 10 and the second stage rocket 20 so that a manufacturing cost of the rockets 10 and 20 can be reduced and a total weight of the rockets 10 and 20 can become lighter by omitting these equipments. Thus, an aerospace vehicle system within the rockets 10 and 20 can be simplified and a launch of the aerospace vehicle can be prepared within a short period.

  • Publication number: 20190202465
    Abstract: If a controller determines the calculation of a measured vehicle body velocity is possible, the controller calculates the measured vehicle body velocity as an estimated vehicle body velocity to conduct update processing for a K table and an AB table. If the controller determines the calculation of the measured vehicle body velocity is impossible, the controller extracts a conversion coefficient from the K table based on a detected running state while extracting a sensitivity coefficient and an offset coefficient from the AB table based on the temperature by a temperature sensor. The vehicle mounted apparatus calculates an axle pulse-based vehicle body velocity from the extracted conversion coefficient while calculating an acceleration-based vehicle body velocity from the extracted sensitivity coefficient and offset coefficient.
