Abstract: A vertical take-off and landing aircraft has an upwardly-open U-shaped channel extending from a front edge to a rear edge of each of two fixed wings and a thrust providing device, such as a propeller, mounted for tilting at the rear end of the channel. The thrust providing device has an inlet at which low pressure is produced by drawing in air along a path and the thrust providing device is tilted to vary the angle of the air drawing-in path relative to the wing and effect vertical take-off and landing by variably enhancing the lift of the wing.

Abstract: Two power sources are connected to a load by a pair of MOSFET control switches, each connected respectively in series between one of the sources and the load, with their integral diodes forwardly biased between the power source and load. An isolating MOSFET switch is connected in series between the pair of MOSFET control switches and the load with its integral diode back biased between the power sources and the load. Two control lines control the on-off state of all three MOSFET switches so that the isolating MOSFET switch is on when either control switch is on and is off when both control switches are off.

The drum has a vent opening with a bushing to which a vent line is attached. A vent line connects the collection drum to the interior of the waste chamber via a valve.

Abstract: An electropneumatic positioner includes an electropneumatic converter, an pilot relay, an operating unit, and a sensor. The electropneumatic converter includes a yoke having central and side leg portions, a permanent magnet arranged on the central leg portion, a pair of coils for exciting the side leg portions to have opposite polarities, a nozzle embedded in one side leg portion to spray air having predetermined pressure, a stopper arranged on the other side leg portion, and a flapper arranged to be swingable on a fulcrum near the central leg portion and serving to change a nozzle back pressure by controlling the amount of air sprayed from the nozzle in accordance with a swing. The electropneumatic converter receives a duty signal, as a driving signal for the coils, which signal is obtained by converting a deviation between an input signal and a feedback signal into a duty. The flapper is set to be parallel to the yoke when the deviation between the input signal and the feedback signal is zero.

Abstract: A motion vector is calculated on the basis of a current block having current block data and a search window having search window data. The search window includes integer pel blocks and half-pel blocks each deviated by half-pel pitch from each of the integer pel blocks. The search window data are repeatedly transferred between and held by the shift registers. The search window data held by the shift registers and the current block data outputted from current block data outputting means are supplied to an integer pel block distortion calculating unit of each of processor elements. The integer pel block distortion calculating unit calculates local distortion values, and each of integer pel block distortion values defined by the local distortion values and indicative of a difference between a current block and each of integer pel blocks on the basis of the received search window and current block data.
