Abstract: A method for manufacturing a cord included rubber sheet has an arrangement step and a cutting step. In the arrangement step, a band-like material of a cord included rubber sheet is supplied to a processing table, and a portion to be cut is arranged onto a groove. In the cutting step, the band-like material is cut by pressing the pressure cutting die, and the cord included rubber sheet having a predetermined length is obtained. A leading end of the pressure cutting die enters the groove and a die surface of the pressure cutting die contacts with an opening edge of the groove, in the cutting step, and a cut surface of the cord is coated with the rubber of the band-like material in a process that the die surface comes into contact with the opening edge after the leading end contacts with the band-like material.

A lightweight and highly rigid tire can be acquired. The tire can also enhance steering stability performance thereof. The pneumatic tire includes: a pair of left and right beads including bead cores 3a; a carcass ply extending between the bead cores: and an inner liner 4 disposed on an inner peripheral side of the carcass ply 5, wherein the carcass ply 5 is wound around the bead cores 3a from the outside in the tire width direction to the inside in the tire width direction, and both end portions of the inner liner 4 extend between the beads and the carcass ply.

Abstract: A pneumatic tire has a carcass ply, a tread rubber, a side wall rubber and a rim strip rubber. A topping rubber of the carcass ply and the side wall rubber are formed by a non-conductive rubber. The rim strip rubber is formed by a conductive rubber. A height of an outer end of the rim strip rubber is equal to or more than 50% of a tire cross section height. JIS A hardness of the side wall rubber is equal to or more than 59 degrees. A side conductive layer formed by the conductive rubber is provided between the side wall rubber and the carcass ply. The side conductive layer is connected to the tread rubber and the rim strip rubber. A conductive route reaching the outer end of the side conductive layer from a ground-contacting surface is constructed in the tread rubber.

Abstract: A pneumatic tire has a tread rubber provided in an outer side of a carcass layer in a tread portion. the tread rubber has a cap portion which is formed by a non-conductive rubber and constructs a ground-contacting surface, a base portion which is provided in an inner side in the tire diametrical direction of the cap portion, and a conductive portion which is formed by a conductive rubber and extends in a thickness direction of the tread rubber so as to reach a bottom surface of the tread rubber from the ground-contacting surface. A thickness of the conductive portion is made relatively large in a center portion in the thickness direction of the tread rubber, and the thickness of the conductive portion is made relatively small in both end portions in the thickness direction of the tread rubber.

Abstract: A pneumatic tire has a plurality of upper surface sipes formed on an upper surface of the block and arranged in parallel so as to be spaced in a sipe width direction, and a wall surface sipe extending along a tire diametrical direction in a wall surface positioned in a longitudinal direction of the upper surface sipe. The wall surface sipe is arranged between a pair of adjacent the upper surface sipes.

Abstract: A pneumatic tire has a plurality of projections extending in a tire width direction while protruding out of an inner surface of a tire. The projections are formed in a region coming to an inner side in a tire width direction than an end portion of a belt layer embedded in a tread portion so as to be spaced in a tire circumferential direction.

Abstract: In a monocrystal producing device using a pulling-down method, a raw material melt 5m is continuously supplied into a crucible 2 to grow a crystal 18 by supplying a powdery raw material 5p onto a premelt plate 3 inside an electric furnace 10 with a powdery raw material supplying device 20 and melting the powdery raw material 5p on the premelt plate 3 to generate the raw material melt 5m, and causing this raw material melt 5m to drop out inside the crucible 2. A dry air is introduced into the powdery raw material 5p inside the powdery raw material tank 6 to prevent moisture of the raw material powder 5p. A transferring tube 9 for transferring the raw material 5m is cooled to prevent the filling in the transferring tube 9 based on melting of the powdery raw material 5p. This makes it possible to produce a monocrystal having a stable chemical composition, a large diameter, and a long size at a low price.

Abstract: A display apparatus for use with a cathode-ray tube capable of displaying patterns in interlaced scanning and non-interlaced scanning operation modes, comprising a composite video signal synthesizer, a memory for storing pattern data, a mode setting circuit for the memory, a data selection signal generator and a raster line number signal generator. The memory stores data for relatively simple patterns such as alphabetical letters and those for relatively complicated patterns such as Chinese characters in individually particular areas in the memory addresses of these different areas are identified by a combination of the data selection signal and the raster line number signal supplied to the memory from the data selection signal generator and the raster line number signal generator. Accordingly, the apparatus is capable of displaying both relatively simple and relatively complicated patterns with satisfactory resolution and with a relatively small-scale structure.

Abstract: A memory selection system which facilitates the addition of an external memory to a digital processing unit having an internal memory is disclosed. When a plurality of memories have the same addresses and an overlapped address is accessed, priority among the memories having the overlapped address is discriminated to enable only the memory having the highest priority (last attached memory) to be selected for access and to disable the access of the other memories.

Abstract: A digital data processing device in which a color memory has a temporal data storage register at input/output interface thereof so that the data write-in or data read-out operations executed by a micro-processing unit (MPU) is always performed through the temporal storage register. When data read-out or write-in operation is made to a character memory at a certain address, the same operation is simultaneously carried out for the color memory at the corresponding address. Assuming that MPU reads out a certain display address of a display screen, a corresponding character code is fetched by MPU from the character memory, while the corresponding color code is transferred to the temporal storage register from the color memory. When MPU performs the write-in operation for another address of the display screen, the character code held by MPU until then is written in the character memory at a designated address, while the color data i.e.
