Title: Automotive interior trim base material
Inventor: HASHIMOTO HIDETO
IPC: B27K9/00
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent the environmental condition of a manufacturing site from becoming worse due to the scattering of small pieces of glass fiber or overcome difficulties in disposing of scraps by forming a bamboo fiber layer on the first surface and/or the second surface of a polyurethane foam base material. SOLUTION: A 4,4'-diphenylmethanediisocyanate is applied to the second surface of a base material 1 consisting of a semihard polyurethane foam sheet or a synthetic resin-impregnated soft polyurethane foam sheet, and a mixed fiber sheet 3 obtained by spraying an acrylic synthetic resin emulsion over a mixture of bamboo fiber and regenerated polypropylene fiber and thermally drying the emulsion after application and impregnation thereof, is laminated on the applied 4,4'-diphenylmethanediisocyanate. A nonwoven fabric resin sheet obtained by integrating the bamboo fiber with a synthetic fiber and/or a synthetic resin precursor may be used instead of the mixed fiber sheet 3. A skin material is applied on the first surface side of a molded interior trim base material.  Thus it is possible to ameliorate the environmental condition of a manufacturing/handling site and easily dispose of the bamboo fiber as a scrap because it is easily flammable and corrosive.

Title: Compression ratio variable internal combustion engine
Inventor: TSUTSUMI SABUROU
IPC: F02D15/04
Filed: 1978-02-10
Abstract: PURPOSE: To improve the rate of fuel consumption by raising the compression ratio especially in a partial by loaded area where the rate of fuel consumption is very low, up to the same value to that in the full loaded state in an ignition type internal combustion engine in which the charging ratio of a working fluid varies with the operational condition of the engine.  
     CONSTITUTION: When the engine runs idle, the amount of necessary air to be introduced into the engine is adjusted by properly turning an idle adjustment screw 20 in linkage with a throttle valve 6 through a cam arm 15, while the lift of a cam 12 in linkage with the cam arm 15 reaches a maximum to push a spring retainer down to the lowest level, fixing a piston linked with the retainer 9 to the lowest side of a cylinder head. Accordingly, when the compression is at a top dead center, the volume of the combustion chamber reaches a minimum, while the mechanical compression ratio reaches a maximum. Thus, the volume of the combustion chamber can properoy be varied according to the charging ratio determined by the throttle value.

Abstract: PURPOSE:To prevent erroneous circuit description by simplifying the preparation of the circuit description to be the input of a circuit analysis tool and shortening preparation time in the case of the electrical characteristic analysis of the circuit extending over plural printed circuit boards. CONSTITUTION:Connection information 7 between the printed circuit boards is referred to at the point of time of extracting circuit information 4 and 5 from substrate design data 1 and 2 of each printed circuit board. After integrating the entire device as one circuit, a circuit description 8 is generated in a form suitable for a circuit analysis step. Thus, the circuit description 8 between the printed circuit boards requires only the simple connection information, resulting in reducing the time taken to the circuit description between the printed circuit boards and errors at the time of preparation. The total processing time can be reduced by attaining efficient processing of imparting an identification name used in the circuit 8 and by giving the connection information between the printed circuit boards before completing the individual circuit description of each substrate.
