摘要： It is an object of the present invention to provide a communication device, a digital signature verification method, and a digital signature generation method, in which the memory usage efficiency is improved without confidential information required for the verification or generation of a signature being easily leaked to the outside.The Java application judges whether signature verification is required for the received signature target data. When judging that signature verification is required, the Java application outputs the received signature target data to the PKI of the platform. The PKI verifies the signature that has been added to the data output by the Java application and performs signature generation, and then notifies the Java application.

摘要： A winding system for winding up a long belt-like material 9 which is fed in a continuous manner, onto a take-up shaft 61. The winding system is provided with a guide belt conveyor for guiding front and rear ends of the belt-like material 9 each up to a predetermined position on the take-up shaft 61, and a dancer roller 18 for applying a certain tension to the belt-like material being wound up onto the take-up shaft. The take-up shaft is mounted on a platform car 60 capable of traveling and it comes into engagement with the winding drive shaft 52 and is thereby rotated. When the platform car 60 is to be changed for another like platform car, the winding drive shaft 52 is retracted in a direction perpendicular to the traveling direction of the platform car to be changed.

摘要： The present invention is concerned with a helical scan type rotary magnetic head device employed for example in a video tape recorder in which the magnetic tape is caused to run obliquely while it contacts the head and in which recording tracks are formed on the magnetic tape at a predetermined angle of inclination relative to the tape. According to the present invention, the tape guide drum along the side of which the magnetic tape is caused to run while contacting with it has a cut-out at its portion free of contact with the magnetic tape, while a rotary transformer adapted for receiving and transmitting recording and/or reproducing signals at or from a rotary magnetic head is mounted so as to be enclosed within the interior of the tape guide drum to reduce the size and thickness of the rotary magnetic head device.

摘要： A magnetic recording and/or reproducing apparatus which includes a rotary magnetic head device, a reel block base plate provided on a chassis plate and having a pair of reel blocks horizontally reciprocable relative to the rotary magnetic head device and operatively engaged with a pair of tape reels of a tape cassette, a cassette holder which is supported by a supporting arm on the chassis base plate so as to be vertically movable relative to the reel block and in which the tape cassette is inserted and retained, an operating mode changeover lever for selecting the various operating modes, including constant speed running, rapid feed and rewind modes, for the magnetic tape pulled out of the tape cassette and loaded into the predetermined tape path, and a drive gear driven into rotation by a driving electric motor, wherein the drive gear is operatively associated with the supporting arm and the reel block base plate. The drive gear is driven into rotation to cause vertical movement of the cassette holder and the reciprocating movement of the reel block base plate. An operating lever adapted for being turned by the drive gear is operatively associated with the operating mode changeover lever, and turned to shift the operating mode changeover lever to select one of the predetermined operating modes. In this manner, the operations of loading the tape cassette and the magnetic tape and of selecting the operating mode may be performed by one and the same driving motor to reduce the number of the driving motors and the size and the thickness of the apparatus, while the cassette attachment and detachment and magnetic tape loading and unloading operations can be performed expeditiously.
