Abstract: There is provided, in one aspect of the present description, an engine. In one example, the engine comprises a cylinder block, a cylinder head, a sheet metal gasket interposed between the block and the head, a first projection projecting outwardly and laterally from a side portion of the block, and a second projection projecting outwardly and laterally from a side portion of the head, the first projection and the second projection facing each other along a coupling surface between the block and the head. The engine further comprises an extension extending from a main body of the sheet metal gasket and located between the first projection and the second projection, and a resilient portion which is provided in the extension, formed resiliently in a direction perpendicular to the coupling surface, and compressed between the first projection and the second projection when the head is fastened on the block.

Abstract: According to this invention, a piston design support program for supporting design of a piston shape of an internal combustion engine, makes a computer execute an input step of inputting specification values associated with a piston shape, a verification step of verifying, based on the input specification values, whether or not gaps between the piston and its surrounding components are appropriate, a read step of reading out, when it is determined in the verification step that the gaps are appropriate, a three-dimensional piston model which can be deformed according to a predetermined rule from a database, and a deformation step of deforming the piston model on the basis of the specification values.

Abstract: A liquid crystal display (LCD) is fixed to an upper housing half by an LCD fixing frame made of a material having a high thermal conductivity. The LCD fixing frame is attached to the upper housing half in contact with a lower surface of the LCD on the opposite side of a display panel which defines an image display plane. A substrate mounted with high heat generating parts such as a CPU is attached to the LCD fixing frame such that the high heat generating parts face the lower surface of the LCD fixing frame. A thermally conductive member is disposed between the high heat generating parts and the LCD fixing frame in contact with the high heat generating parts and LCD fixing frame.

Abstract: A directory structure corresponding to a plurality of applications is formed. Items of identification information are given to predetermined directories of the directory structure, respectively, the items of identification information being used for identifying the plurality of applications, respectively, the plurality of applications corresponding to the predetermined directories, respectively. Management is performed so that an application of the plurality of applications corresponding to a directory of the predetermined directories is selected in accordance with an item of the items of identification information given to the directory of the predetermined directories, when the directory of the predetermined directories is selected.
