Abstract: Provide a laminate constituted by epichlorohydrin rubber layer and fluororubber layer that are strongly vulcanization-bonded together. A rubber laminate constituted by vulcanization-bonding an epichlorohydrin rubber layer that contains at least (a) magnesium oxide, (b) polythiol vulcanizing agent, (c) at least one type of compound selected from 1,8-diazabicyclo (5,4,0) undecene-7,1,5-diazabicyclo (4,3,0) nonene-5, and salts thereof, (d) at least one type of compound selected from organic phosphonium salts and organic ammonium salts, and (e) maleic anhydride modified polybutadiene, and a fluororubber layer; wherein such rubber laminate is characterized in that: the content of the polythiol vulcanizing agent (b) in the epichlorohydrin rubber layer is 0.3 to 1.2 parts by weight per 100 parts by weight of the epichlorohydrin rubber; and the content of the maleic anhydride modified polybutadiene (e) in the epichlorohydrin rubber layer is 0.3 to 1.

Abstract: A vulcanization-adhered laminate is constituted by a structure where a fluororubber layer and a synthetic rubber-containing layer are tightly adhered by vulcanization by vulcanization, and the synthetic rubber layer prior to the vulcanization-adhesion includes organic peroxide, silica, organic phosphonium salt, maleic anhydride-modified polybutadiene, and magnesium oxide.

Abstract: A document editing device for editing a document having a hierarchial structure by sets of element which share definition information on existence and format of serial number and heading title of a text which includes chapters and sections, comprises a document data memory for storing text data with a control character indicating the modification of a hierarchial level of the set and a control character indicating the end of each element being added to a position in the text data corresponding to the heading, and a management information memory for storing management information for each set and each element separately from the text data. When the text data is to be displayed or printed, the control character is detected from the text read from the document data memory, the serial number and title corresponding to the detected control character are read from the management information memory and they are outputted in place of the control character.

Abstract: A combination of an air cleaner for cleaning intake air to be inhaled by an internal combustion engine and a deceleration compensating air control valve for controlling supply of secondary air to the intake manifold of the engine during engine deceleration, wherein the deceleration compensating air control valve is mounted in the clean air space provided in the air cleaner casing at the inner side of an annular filtering element mounted in the air cleaner casing, or is mounted at the outside of the air cleaner casing, so that, in both cases, the air inlet port of the deceleration compensating air control valve is directly open to the clean air space.
