Abstract: Information that is required for laying out character string data is entered, as are character string data. The printing attributes for the data are then edited, and are employed to extract contour information. Thereafter, the extracted contour information is employed to determine the information that is to be used as a reference when laying out the character string data, and a layout position is specified. Then, the various data that are obtained are stored as printing data, and the character string data are laid out in a drawing area. Therefore, the printing data can be precisely and easily prepared, without the work efficiency of a user being deteriorated.

Abstract: The present invention provides a fiber base material for constituting a composite material for increasing interlaminar strength (peeling strength, out-of-plane strength, post-impact strength), improving impregnation efficiency of a matrix in a composing process and preventing a resin-rich portion that affects the strength. A fiber base material for constituting a composite material comprising a single layer or a plurality of layers of a solid-shape base material constituted of a woven or knitted continuous fiber, wherein the base material is raised for enhancing interlaminar or bonding plane strength, improving permeability of a matrix at a surface and an interior portion thereof, and increasing plane smoothness.

Abstract: Ketone compounds having marine-like, modern green-like and fatty green-like fragrance and flavor, and fragrance compositions and flavor compositions containing the same.

Abstract: A multi-cylinder internal combustion engine includes an intake manifold having branch pipes connected to one side of a cylinder head and curved to allow the intake manifold to extend to directly above a cylinder-head cover, and intake-side spark plugs and fuel injectors which are incorporated in the cylinder head. The spark plugs are disposed outside a valve train chamber on a side of the valve train chamber where curved portions of the branch pipes are disposed, and the fuel injectors and ignition coils provided above the spark plugs are disposed between the valve train chamber and the curved portions in a direction normal to axes of the cylinders as viewed from a direction in which cylinders are arranged. The ignition coils are disposed so as not to overlap the branch pipes as viewed from a direction in which the ignition coils are attached to the cylinder head.

Abstract: The present invention relates to a graphics processing apparatus for plotting three-dimensional graphics by using a grid, and to a method of use of the apparatus. An arbitrary plane grid is displayed on a display screen, the displayed grid is variously changed and the three-dimensional graphic is plotted using the changed grid. The possible changes of the grid include a grid translation, a grid spacing change, a grid rotation, the selection of a grid display/non-display mode, coincidence/non-coincidence of the reference points of the graphic with the grid, and the like. Also, the apparatus executes a corner processing, including arc processing and straight line processing. In the arc processing, the corner processing is executed by selecting two straight lines and inputting a radius to define a corner joining the two lines; and in the straight line processing, the corner processing is executed by selecting two straight lines and inputting the length and angle of a line segment to join them.
