摘要:
A resin molded object 1 that may be used as a sunroof has a reinforcing rib 3 around the periphery of a window body 2 that is disposed inside a car. The window body 2 is molded using a fixed die 7 and one molding surface 8a of a first movable die 8, then the reinforcing rib 3 is molded on the window body 2 using the fixed die 7 and a second molding surface 8b of a second movable die 8 to thereby to fabricate a double-molded resin window.

Novel cephalosporins which has attached to the exomethylene group at the 3-position of the cephem ring a substituted or unsubstituted aryl, acylamino, aromatic heterocyclic, triazolyl or tetrazolyl group, said aromatic heterocyclic group being attached through a carbon-carbon bond and said triazolyl or tetrazolyl group being attached through a carbon-nitrogen bond, and has the following group attached to the amino group at the 7-position: ##STR1## wherein A represents a group of the formula, --CH.sub.2 -- or a group of the formula ##STR2## in which R.sup.5 represents a hydrogen atom or an alkyl group, and the bond.about.represents syn or anti isomer or their mixture; R.sup.3 represents a hydrogen or halogen atom; and R.sup.4 represents a hydrogen atom or an amino group which may be protected or substituted. These cephalosporins have a broad antibacterial spectrum, are stable against .beta.-lactamase produced by bacteria, have a low toxicity, and are well absorbed when administered orally or parenterally.

Provided is a fiber-reinforced thermoplastic resin molded article, which contains reinforcing fibers having a given flattened cross-sectional profile, in which the fiber length distribution of the reinforcing fibers is shifted on the side of long fibers, and which is excellent in mechanical strength, heat resistance, dimensional accuracy such as warpage resistance, and surface appearance.
摘要:
A method of coding and transmitting moving pictures includes the steps of coding an extended background image, coding parameters indicative of an image area within the extended background image, coding a foreground picture that is to be composed with a background picture corresponding to the image area indicated by the parameters, coding a defocus value indicative of an extent to which the background picture should blur, and transmitting the coded extended background image, the coded parameters, the coded foreground picture, and the coded defocus value as a data stream to a decoder side. Coding and transmitting of the defocus value makes it possible to defocus the background picture at the decoder end, thereby producing a composed image of the background picture and the foreground picture having natural appearance.

摘要:
This invention relates to novel 7-(substituted or unsubstituted amino)-3-substituted methyl-.DELTA..sup.3 -cephem-4-carboxylic acids in which a substituted or unsubstituted 1,2,4-triazolyl or 2-(1,2,3,4-tetrazolyl) group attaches to the exomethylene group at the 3-position of the cephem ring through a carbon-nitrogen bond. These cephalosporins are useful intermediates for producing various novel cephalosporins. Also, this invention concerns a process for producing a compound represented by the formula: ##STR1## which comprises reacting a compound represented by the formula: ##STR2## with an optionally substituted triazole or tetrazole in the presence of an acid or a complex of the acid in an organic solvent at 0.degree. to 80.degree.
