A method and an apparatus of simple construction for manufacturing a pneumatic tire are provided. Belt wave and unevenness of belt gauge are restrained at a minimum, joining of joint parts is ensured, installation space can be smallest within the limit of necessity and equipment cost is low. In a method for manufacturing a pneumatic tire by charging a green tire having tire components assembled in a mold for vulcanization-molding and forming lug grooves on a tire tread surface, carved grooves are previously formed at positions on a surface of the green tire corresponding to the lug grooves extending in substantially the same direction as the lug grooves.

A sputtering target is provided that includes SiC and metallic Si and has an atomic ratio of C to Si of from 0.5 to 0.95 and a density of from 2.75×103 kg/m3 to 3.1×103 kg/m3. The sputtering target is capable of forming at high speed a film that contains SiO2 as the main component and has a low refractive index. The sputtering target can be produced by a process in which a molded product of SiC is impregnated with molten Si.

There is provided a process of producing a ring shaped resin bonded magnetic member by molding a feed mixture 24 which contains a lubricant and a magnetic powder composite made of magnetic powder and a heat curable resin composition which is in a solid state at a room temperature. The process is characterized in that (1) heating an inner peripheral surface of the annular cavity 20 so as to transfer heat to the feed mixture 24 whereby heating the feed mixture to a temperature not lower than a softening temperature and below a curing temperature of the resin composition, and compressing the filled feed mixture after or during the heating; and (ii) cooling the inner peripheral surface so as to transfer heat from the heated and compressed feed mixture through the inner peripheral surface, whereby cooling the feed mixture to a temperature below the softening temperature of the resin composition so as to obtain a green compact having a ring shape.

An information recording medium includes a disk information area; a user area including a plurality of sectors; and a spare area including at least one sector which, when at least one of the plurality of sectors included in the user area is a defective sector, is usable instead of the at least one defective sector. The spare area is located radially inward from the user area. A physical sector number of a sector to which a logical sector number “0” is assigned, among the plurality of sectors included in the user area and the at least one sector included in the spare area, is recorded in the disk information area.

In a pair of electrodes where a potential difference is changed in accordance with acidity or basicity of oil, a reference electrode is made of cobalt or a cobalt alloy, and a sensitive electrode is made of tungsten or a tungsten alloy. The sensitive electrode is used in combination with the reference electrode. Accordingly, it is possible to provide a pair of electrodes for detecting the acidity or the basicity of the oil which use a novel electrode material not hazardous to the environment and at the same time, suited for use in a semiconductor fabrication technique.

A sheet for protecting paint films of automobiles which can prevent the paint film of automobiles from suffering from damages such as discoloration and denaturation even if rainwater or washer penetrates into the gap between the adhesive cover and the paint film while achieving excellent protection function to suspended matters, colliding matters, etc. inherent to protecting sheets and being easily peeled off and removed after completion of the desired protection. The sheet for protecting paint films of automobiles comprises a pressure-sensitive adhesive layer having a roughened surface provided on a substrate made of fiber sheet. Even when rainwater, washer, etc. penetrates into the gap between the pressure-sensitive adhesive layer and the paint film of automobiles from wrinkles formed thereon, the liquid diffuses by capillary action through the gap developed by the roughened pressure-sensitive adhesive layer, making it possible to avoid the residence and concentration of the penetrated dirty water and hence prevent the occurrence of damages such as discoloration and denaturation of the paint film. Further, the arrangement of a pressure-sensitive adhesive layer having a roughened surface reflecting the fiber constituting the protecting sheet, particularly a fibrous continuous roughened surface, makes it possible to further diffuse the contaminating dirty water and hence further avoid the retention and concentration of the penetrated dirty water. Thus, the damages on the paint film can be more securely prevented.
