TL;DR: In this paper, the authors proposed a method for producing a gas-barrier film, which is satisfactory in productivity, exhibits high gasbarrier property immediately after production, and has excellent adhesive strength between constituent layers.
Abstract: Provided are a method for producing a film, which is satisfactory in productivity, exhibits high gas-barrier property immediately after production, and has excellent adhesive strength between constituent layers while maintaining the excellent gas-barrier property, and a gas-barrier film, which is obtained by the method. The method for producing a gas-barrier film includes the steps of: (1) forming an inorganic thin film by a vacuum deposition method on at least one surface of a base film; (2) forming a thin film by a plasma CVD method on the inorganic thin film formed in the step (1); and (3) forming an inorganic thin film by the vacuum deposition method on the thin film formed in the step (2), in which each of the steps (1) and (3), and the step (2) are sequentially carried out at a pressure of 1×10 -7 to 1 Pa, and at a pressure of 1×10 -3 to 1×10 2 Pa, respectively.

TL;DR: A new design scheme of PID controllers based on a data-driven (DD) technique is proposed for nonlinear systems that can adjust the PID parameters in an online manner even if the system has nonlinear properties and/or time-variant system parameters.
Abstract: Since most processes have nonlinearities, controller design schemes to deal with such systems are required. On the other hand, proportional-integral-derivative (PID) controllers have been widely used for process systems. Therefore, in this paper, a new design scheme of PID controllers based on a data-driven (DD) technique is proposed for nonlinear systems. According to the DD technique, a suitable set of PID parameters is automatically generated based on input/output data pairs of the controlled object stored in the database. This scheme can adjust the PID parameters in an online manner even if the system has nonlinear properties and/or time-variant system parameters. Finally, the effectiveness of the newly proposed control scheme is evaluated on some simulation examples, and a pilot-scale temperature control system.

TL;DR: In this paper, the authors propose a control unit for calculating an error level from the difference between the average power level and a reference power level which corresponds to a predetermined power of the RF output signal.
Abstract: APC circuitry used for a radio transmitter comprises a detector (7) which detects a radio frequency (RF) output signal (5) to output a detection signal (8), an integrator (15) which integrates the detection signal (8) to output a power signal (16) representing the average power level of the RF output signal (5), a control unit (18) for calculating an error level from the difference between the average power level and a reference power level which corresponds to a predetermined power of the RF output signal (5), and for multiplying the error level by a correction coefficient so as to calculate a control signal correction value for correcting the value of a control signal (14) and then generate control data the digital value of which is corrected according to the control signal correction value and a reference control value that is predetermined so as to generate the RF output signal (5) having the predetermined power.

TL;DR: The results suggest that Mos is located upstream of MAPK in mouse oocytes as in Xenopus oocytes but is independent of MPF activity, and that Mos/MAPK is not necessary go GVBD and first polar body emission.
Abstract: In Xenopus oocytes, Mos activates the mitogen-activated protein kinase (MAPK) signal transduction cascade and regulates meiosis. In mammalian oocytes, however, the functions of Mos are still unclear. In the present study, we used c-mos knockout mouse oocytes and examined the roles of Mos in mouse oocyte maturation and fertilization, including whether Mos controls MAPK and maturation promoting factor (MPF) activity. The kinetics of germinal vesicle breakdown (GVBD) and the first polar body emission were similar in wild-type, heterozygous mutant, and homozygous mutant mice. Activities of MPF were also not significantly different among the three genotypes until the first polar body emission. In contrast, MAPK activity in c-mos knockout oocytes did not significantly fluctuate throughout maturation, and the oocytes had abnormal diffused spindles and loosely condensed chromosomes, although a clear increase in MAPK activities was observed after GVBD in wild-type and heterozygous mutant oocytes that had normal spindles and chromosomes. After the first polar body emission, 38% of c-mos knockout oocytes formed a pronucleus instead of undergoing second meiosis, indicating the crucial role of Mos in MPF reactivation after first meiosis. When oocytes that reached second metaphase were fertilized or stimulated by ethanol, many c-mos knockout oocytes emitted a second polar body and progressed into third meiotic metaphase instead of interphase, although all fertilized or activated oocytes in the heterozygote progressed to interphase, indicating that Mos deletion leads to compensatory factors that might not be degraded after fertilization or parthenogenetic activation. These results suggest that Mos is located upstream of MAPK in mouse oocytes as in Xenopus oocytes but is independent of MPF activity, and that Mos/MAPK is not necessary for GVBD and first polar body emission. Our results also suggest that Mos plays a crucial role in normal spindle and chromosome morphology and the reactivation of MPF after first meiosis.

TL;DR: In this article, an action feasibility judging unit is used to judge the feasibility of an action in the goal frame and if the action is judged to be feasible, it outputs an action command to an external application.
Abstract: A user goal extracting unit extracts a user goal from an input statement 10 entered by a user. A system goal determining unit 15 determines a system goal in accordance with the user goal. A goal frame generating unit 17 generates a goal frame based on an action sequence knowledge corresponding to the system goal. An action feasibility judging unit 19 sets arguments for, and judges the feasibility of, an action in the goal frame. If the action is judged to be feasible, the action feasibility judging unit 19 outputs an action command to an external application 20. If the action is not judged to be feasible, the action feasibility judging unit 19 outputs a new system goal to the goal frame generating unit 17. The external application 20 outputs a result of execution of the action.
