  • 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: 10511249
    Abstract: A motor driving device controls driving of an inverter device, detects current values in two phases, and compensates a value. The motor driving device detects current values in two phases, namely, a maximum phase current value and a minimum phase current value, within a single cycle of a PWM carrier frequency. The motor driving device compensates a value obtained by subtracting an absolute value of a difference between two absolute values, namely, the detected maximum phase current value and minimum phase current value, from the smaller value of the absolute values, as the offset current component.

  • 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.

  • Patent number: 10480067
    Abstract: A film deposition method for filling a recessed pattern with a SiN film is provided. NH2 groups are caused to adsorb on a surface of a substrate containing a recessed pattern formed in a top surface of the substrate by supplying a first process gas containing NH3 converted to first plasma to the surface of the substrate containing the recessed pattern. The NH2 groups is partially converted to N groups by supplying a second process gas containing N2 converted to second plasma to the surface of the substrate containing the recessed pattern on which the NH2 groups is adsorbed. A silicon-containing gas is caused to adsorb on the NH2 groups by supplying the silicon-containing gas to the surface of the substrate containing the recessed pattern on which the NH2 groups and the N groups are adsorbed. The above steps are cyclically repeated.
