An internal combustion aircraft engine comprising a cylinder head having a cylindrical head bore formed therein, a piston, and spark plugs, the cylinder head bore and piston designed to reduce engine knock. The cylinder head is fixedly attached to a top end of a cylinder barrel formed with cylindrical walls, the cylinder head bore and the cylindrical walls defining a cylinder. The cylinder head bore has formed therein an outwardly protruding cavity with respect to the top end of the cylinder barrel. The piston has a piston crown, and the piston contained within the cylinder, the piston crown, the cylinder walls, and the cylinder head bore define a combustion chamber. The piston crown has a concavity formed therein, and the piston is constructed and arranged to reciprocate within the cylinder. The concavity of the piston crown and the cavity cooperate at a top dead center position of the piston to form a swirl chamber. The piston crown has formed along a peripheral edge thereof a squish area that corresponds to a second squish area formed in the cylinder head bore, so that when the piston approaches top dead center, the squish area and the second squish area cooperate to cause combustion gases to move radially inward of the combustion chamber and into the swirl chamber. Spark plugs extend through the cylinder head, the tips of which are disposed within the swirl chamber.

A vehicle 1000 is equipped with a fuel cell system 100 and a secondary battery as power sources. A water level of water present on a water-covered road surface is measured by a water level sensor 72. When the measured water level reaches or exceeds a preset threshold value, drive control of the vehicle 1000 stops power generation by a fuel cell stack 10, closes a discharge valve 62, and enables the vehicle 1000 to be driven with output power of a motor that is actuated with electric power from the secondary battery. This arrangement effectively prevents a damage or failure of the fuel cells mounted on the vehicle moving on the water-covered road.

A medium writing apparatus obtains information to be written onto a recording medium, converts the information into a suitable writable format, and then writes the converted information onto the recording medium. An ID obtaining section obtains a medium ID from the recording medium, or through an input by the user. The medium ID and information indicating the place of the written information are sent to a server, and then stored as index information correlating them with each other. When the information written onto the recording medium is to be used at a later timing, the medium ID is identified, and the index information is obtained from the server. Therefore, the original information can be obtained so as to be easily reprocessed or reused.

A writing device constituting an electronic book includes a connector to which electronic papers are detachably connected. The number of connected sheets of electronic paper is recognized, and is output to a host computer. In the host computer, display data is output on the basis of the number of electronic papers, and the display data is written in the electronic papers by a write control unit. When a change of connections of the electronic papers is detected by the detection unit, a part of images displayed on the electronic papers is rewritten depending on the detected connection states of the electronic papers by which optimum images on the electronic papers are displayed even if an arbitrary electronic paper is attached or detached.

A driving method of a liquid crystal device for recording an image, the liquid crystal device including a liquid crystal layer having a cholesteric liquid crystal, a photoconductor layer accumulated on the liquid crystal layer, and electrodes, includes initializing an entire liquid crystal layer to a focal conic texture by applying a voltage exceeding a threshold value of transition from a planar texture to a focal conic texture, exposing the liquid crystal device imagewise while applying a voltage not exceeding a threshold value from the focal conic texture to a homeotropic texture upon non-exposure but exceeding the threshold value upon exposure and that provides bistability of the focal conic texture and the homeotropic texture with hysteresis upon non-exposure, and fixing a displayed image by releasing an application of voltage to change a part of the liquid crystal layer changed to the homeotropic texture to the planar texture.

The present invention reduces the burden on a target object such as a test subject by acquiring multi perspective video image data by photographing the target object by means of a plurality of cameras and acquires the actual movement including a picture of the target object independently of the measurement environment by acquiring camera parameters such as the attitude and zoom of the camera along with picture data. By acquiring video image data by synchronizing a plurality of cameras during photographing by the cameras and at the same time acquiring camera parameters in sync with the video image data, rather than simply acquiring video image data and camera parameters, the present invention acquires the actual movement of the target object independently of the measurement environment and acquires the movement of the video image itself of the target object rather than movement of only representative points.

In a small display system in which the area of each of a display device and a driving device is approximately reduced to the area of an image display part, the display device having the image display part and the driving device having a driving IC for driving the display device can be attached to or detached from each other. Display device-side electrode terminals connected to lines for driving individual display pixels of the display device are provided on the reverse surface of the display device opposite to the image display part. Driving device-side electrode terminals corresponding to the respective display device-side electrode terminals are provided on the display device connecting part of the driving device. When the display device is attached to the driving device, both the driving device-side electrode terminals and the display device-side electrode terminals are electrically connected so that an image can be displayed on the display device by the driving device.
