Abstract: When the recording is started, recording information for information data is saved. When the supply of power has been recovered, the NWA and the LBN at the title head are reproduced based on the recording information. When RDI is present in a VOBU, and when a sequence code is not present in the VOBU, the reading of the first sector of the succeeding VOBU is repeated. When RDI is not present in a VOBU, or when a sequence code is present in the VOBU, the RTR_VMGI is created, the number of recorded titles that are saved is compared with the number of titles obtained when the supply of power has been recovered. Until there are no more following titles, reproduction of the LBNs at the title head is repeated. And when there are no more following titles, the RTR_VMGI is written to the optical disk.

Abstract: In an optical disk recorder which records data in a recordable form in compliance with UDF, when writing of a data block constituting a user data file and a control data file is failed (NO in #2), that data block is rewritten (#5). When the writing of all data constituting the user data file and the control data file is completed (that is, when the writing of the data block constituting the user data file and the control data file is completed) (YES in #3), FE, VAT, and VATICB, which are file management data, respectively, are written (#6). When the writing of the FE, the VAT, and the VATICB are failed (NO in #7), that FE, VAT, and VATICB are rewritten (#8), and when the writing of the FE, VAT, and VATICB is completed (YES in #7), a recording operation is completed. Thereby, even when reproducing the data in the data file from the optical disk in which the writing of the data in the data file is failed, the data in the data file can be reproduced with the rewritten data correctly.

Abstract: A (meth)acrylate-grafted polyether polyol produced by reacting 40 to 95 parts by weight of a polyoxyalkylene polyol and 5 to 60 parts by weight of a vinyl monomer, both relative to 100 parts by weight of the sum total of the polyoxyalkylene polyol and the vinyl monomer, and 0.1 to 5 moles of an alkyl peroxide as a radical initiator per mole of the hydroxyl group in the polyoxyalkylene polyol, wherein the polyoxyalkylene polyol has a hydroxyl number of 25 mg KOH/g or less, and the vinyl monomer contains a (meth)acrylate and/or a hydroxyl-containing (meth)acrylate in an amount of 50% by weight or higher. The (meth)acrylate-grafted polyether polyol is excellent in colorless-transparency, compatibility, mechanical strength, weather resistance, and blending resistance, and therefore is useful as a raw material for a polyurethane resin cured article.

Abstract: In an optical disk recorder which records data in a recordable form in compliance with UDF, when writing of a data block constituting a user data file and a control data file is failed (NO in #2), that data block is rewritten (#5). When the writing of all data constituting the user data file and the control data file is completed (that is, when the writing of the data block constituting the user data file and the control data file is completed) (YES in #3), FE, VAT, and VATICB, which are file management data, respectively, are written (#6). When the writing of the FE, the VAT, and the VATICB are failed (NO in #7), that FE, VAT, and VATICB are rewritten (#8), and when the writing of the FE, VAT, and VATICB is completed (YES in #7), a recording operation is completed. Thereby, even when reproducing the data in the data file from the optical disk in which the writing of the data in the data file is failed, the data in the data file can be reproduced with the rewritten data correctly.

Abstract: A discharge device for worked material is provided. The worked material produced by the press working is received on a chute arranged just below a lower die. The chute is driven to make a reciprocating motion within a substantially horizontal plane in response to a die stroke. At a moment of stopping of the forward movement of the chute, an inertia force acting on the worked material from the chute is greater than a static frictional force. Or otherwise, a force taking effect upon starting of a backward movement of the chute is greater than the static frictional force. Consequently, the worked material is due to be discharged from the chute.
