When reading a sector, the software program discards the first few few bytes is would possibly learn until it sees the 0x5A sync byte. To solve this, the formatter writes three dummy 0xFF bytes between the ID block and the info block. Once the appropriate observe and sector are discovered, the software program switches on the write enable and then writes the info block. However, there are several problems, in the management cable in which a lubricant is used, corresponding to difficulty of operation for coating as a result of dispersion of the load effectivity of merchandise is attributable to the unevenness of a coating, rubbishes and dusts are simply adhered to the lubricant when applying the lubricant to the management cable, and drip and the like are generated. As an example, in case the shortage of lubricants is generated because of the lengthy period use of the management cable, there are some problems that the liner is totally worn down and the operationability of the management cable is excessively lowered, and the like. Among them, polyoxymethylene is ideally used in the present invention because a stickslip is hardly generated when polyoxymethylene is used.
The polyoxymethylene additionally has properties similar to low stickslip beneath a excessive load and improves the operationability of a control cable. When the melt index of the excessive density polyethylene is lower than 0.01 g/10 minutes, the extrusion molding turns into tough, and there is a tendency that the inside coat can't be fastened on a stranded steel wire. Also, a artificial resin coating (hereinafter referred to as inside coat) is ready on the outer surroundings of the inner cable. Also, as a resin of the inside coat, a thermoplastic resin through which the above-talked about organopolysiloxane is dispersively contained will be utilized in the identical approach as in the above-talked about liner. Also, the durability of the above-mentioned management cable largely depends upon the lubricant. Also, the organopolysiloxane may be ready to grease. The thing of the present invention is to delete the above-talked about disadvantages of conventional management cables and to provide a control cable which does not necessitate a lubricant to keep away from a fancy coating operation and which can be utilized with smooth sliding operation of the interior cable for a long period of time.
However, a large amount of the organopolysiloxane having a high viscosity will be contained within the resin, and the molding could be carried out with out slipping. When the content material of the organopolysiloxane having an ultra-excessive viscosity is much less that 45% by weight and the content of the organopolysiloxane having a lower viscosity is more that 55% by weight, an extruded product can't be produced as a result of a slide between a screw and a resin happens in an extruder and the feed of the resin can't be carried out. A load cell 14 was related with the inside cable 1 on the best way at the input side, and another load cell 15 was related with the internal cable 1 on the way in which on the out put facet. In order to improve the load effectivity of a management cable with out a lubricant, an organopolysiloxane is contained in a resin for a liner or an internal coat, and the organopolysiloxane extides from on the floor of the resin.
Therefore, in some cases, as diclosed in Japanese Patent Unexamined Publication No. 231009/1985, a flexible tubular liner made from a synthetic resin is formed on the inside floor of the conduit. Next, the liner was inserted into a conduit having a protective layer fabricated from polypropylene of 0.7 mm in thickness on the surface floor of a springy armor layer having an out of doors diameter of 8.6 mm. Among them, dimethylpolysiloxane is especially preferable from the viewpoint of lubricationability between the thermoplastic resin of the liner and that of the inner coat, thermal resistance, price, and the like. Within the above-talked about liner, a thermoplastic resin containing 13 to 20% by weight of an dispersed in the resin, is used. The conduit 2 is composed of an armor layer 5 and a protecting layer 6 of a synthetic resin corresponding to polypropylene. However, in such a control cable, frictional resistance increases when the conduit is instantly contacted with the interior cable. As the bodily properties of the management cable, load effectivity was measured in accordance with the next technique.
