A modified conjugated diene-based polymer is produced that is a modified product of a conjugated diene-based polymer obtained by polymerizing a conjugated diene compound, or polymerizing a conjugated diene compound and an aromatic vinyl compound, in the presence of an alkali metal compound or an alkaline-earth metal compound. The modified conjugated diene-based polymer is produced by a production method that includes a main chain modification step that reacts at least either an unsaturated bond or a functional group that is included in a terminal-modified polymer and is not situated at a terminal of the terminal-modified polymer, with a specific compound that includes a functional group that interacts with silica, the terminal-modified polymer being obtained by introducing a functional group that interacts with silica into at least one terminal of the conjugated diene-based polymer.

A sound reproducing system that decodes audio data in a frame with which detection of a syncword fails, if a syncword included in a subsequent frame is detected, if correctness of bit stream information in the subsequent frame is proved, and if no CRC error is detected (when CRC is included). This makes it possible to solve a problem involved in a conventional system in that when a unit frame without an error check pattern is input and a synchronization detector produces a synchronization detection error signal, unpleasant sound interruption can take place even if the audio data is correct, because the correctness of the audio data cannot be checked, and hence the audio data cannot be decoded in this case.

In a method of producing a semiconductor laser element with suppression of mirror degradation by the laser light which can operate stably with a high output power, a laser wafer is prepared to have a layered structure of semiconductor layers including an active layer, followed by forming contact electrodes on the top and the bottom of the wafer, cleaving the wafer in a ultra high vacuum chamber to provide a laser bar, and covering cleaved end faces of the laser bar with semiconductor amorphous layers, as protective layers, of a compound semiconductor material between a third group element and a fifth group element in the element periodic table, to form a protected laser bar. An example of the amorphous layer is of GaAs semiconductor material. Then, a laser element without mirror degradation is obtained by forming dielectric films on the protective layers. Alternatively, the protected laser bar is introduced into a chloride VPE apparatus wherein the protective layers are removed and window layers are formed on the cleaved end faces. Then, dielectric films are formed on the window layers to complete another laser element with mirror degradation suppressed.

In a semiconductor laser, a first dielectric layer is formed on the front face of a laser diode for producing a compressive stress, and a second dielectric layer is formed on the first dielectric layer for producing a tensile stress for counteracting the compressive stress of the first dielectric layer. The first dielectric layer is formed of a substance such as Al.sub.2 O.sub.3 and the second dielectric layer is formed of a substance such as SiN.sub.x. A high stability into is created between the first dielectric layer and the front face of the laser diode to prevent it from suffering from a castrophic optical damage.

A method of attaching a cutter to a carton includes the steps of feeding intermittently a nonmetallic sheet by a feeding device toward upper and lower molds, one of which is vertically movable, punching the nonmetallic sheet by the molds to form the cutter, conveying and setting cartons one by one by a conveying device, sucking and holding the cutter on the movable mold, and pressing the cutter to the carton which is adhered thereto by an adhesive paste applied to the cutter. The nonmetallic sheet has an adhesive paste on one side and a removable sheet on the paste which is peeled away prior to punching.

A thin film of molten polypropylene resin extruded from a T die is pressed and cooled with a chill roll equipped with a hologram relief master plate on its peripheral surface, whereupon a hologram pattern is simultaneously formed as an integral part of the polypropylene resin sheet being molded. Since the polypropylene resin has a Rockwell hardness of at least 70, the hologram pattern formed in the resulting hologram forming sheet is less likely to be damaged or lost during subsequent processing.
