The invention relates to a convertible aircraft operating method. According to the invention, the aircraft comprises: a fuselage, standard fixed wings which are equipped with ailerons, a tail unit with flight-control surfaces, engines, a rotor with blades, a transmission which is placed between the engines and the rotor and which is equipped with rotor clutch and braking means, a landing gear, means for transition from helicopter mode to autogyro mode and vice versa, and means for direct or reverse transition from autogyro / helicopter mode to aeroplane mode. The lift for a range of low speeds is produced by means of the rotor, while the lift for a range of high speeds is produced by means of the wings. In addition, the lift for a range of intermediate speeds can be produced using the wings and the rotor in autogyro mode simultaneously, and take-off and landing can be performed in autogyro mode or in helicopter mode with the engines coupled to the rotor. The aircraft comprises a hybrid helicopter / autogyro / aeroplane aircraft and, as such, can perform the direct or reverse transition to aeroplane mode from both helicopter mode and autogyro mode.

A control system for a plug-in hybrid vehicle includes a drive system including a starter motor, a transverse engine, and a motor / generator, and a power supply system including a high voltage battery, a capacitor, and a hybrid control module that controls charging and discharging of the capacitor. In the control system for an FF plug-in hybrid vehicle in which an external charging of the high-power battery is available, the hybrid control module starts the starter, performs mode selection control and charge / discharge control, maintains a capacitor voltage at or below a deterioration free voltage when the CS mode is selected during ignition on, and recharges the capacitor to a starter start-up permission voltage that allows the starter to start when a pre-forecast of the reverse transition from the CS mode to the CD mode is established.

The invention concerns arrays comprising hundreds, thousands, to hundreds of thousands of samples and methods for screening thereof.

In an OCB liquid crystal display device, a gradation voltage of a video signal is set to be lower than a black display optimum voltage, and a reverse transition prevention voltage is set to be higher than the black display optimum voltage and to be lower than a maximum applied voltage, and as the gradation voltage of the video signal becomes low, the reverse transition prevention voltage is set to be high.

The invention relates to an electronically controlled two-way three-state clutch. When realizing the two-way three-state clutch control of forward and reverse transmission and separation, most of the clutch structures are complicated. It consists of forward rotation power output body, reverse power output body and transition body. Driven by the controllable rotation of the electronically controlled power input shaft, when the shaft sleeve with external thread is screwed into the internal thread of any one of the forward and reverse power output bodies, it passes through the stop surfaces set on both sides. Fit and drive together to realize forward and reverse transmission; when the shaft sleeve with external thread rotates under the accurate position control of the electronically controlled power input shaft and slides axially to the relatively static transition body position in the middle of the forward and reverse power output bodies , the electronic control power input shaft is separated from the forward and reverse power output bodies, so that the two-way three-state clutch of one clutch and two clutches can be realized through the coordinated action of mechanical and electronic control integration.
