Title: Terminal authorizing method
Inventor: TATEBAYASHI MAKOTO
IPC: G06F21/34
Filed: 1987-10-13
Abstract: PURPOSE:To prevent leaking of secrecy authorizing information to a third person by making information a different number each time of authorizing action even when it is obtained on the communication line between terminals in order that the terminal is recognized as a valid one. CONSTITUTION:In the random number generation part 33 of an IC card terminal 1, generates random numbers R that differ every when they are generated, a cipher device 34 enciphers the random number R with secrecy authorizing information S1 for ciphering key, and a number X is thus generated. A decoder 45 decodes the transmitted number X with secrecy authorizing information S2 for decoding key, and a number Y is thus generated. A cipher device 44 enciphers the number Y with common information C2 for enciphering key to generate a number Z. A decoder 35 decodes the number Z with the common information C2 for decoding key to generate a number U. In case the number U and the random number R does not coincide with each other, the IC card terminal 1 does not authorize the IC card 2 as valid, because, if the bits of secrecy authorizing information S2 and that S1 differ from each other, the number Y and that R must also differ from each other, and the result of the enciphering/ decoding of the number Y with the common information for ciphering key will not coincides with the random number R.

IPC: G11B17/32
Filed: 1989-10-02
Abstract: PURPOSE:To improve the contact characteristic of a head and to set a small spacing loss by providing a head element supported by gimbals at about the center in a cylindrical cylinder whose slider surface facing a medium is annular. CONSTITUTION:When a head 16 supported by a gimbal 6 at about the center in a cylindrical slider 1 is pressed to a floppy disk 4 and the disk 4 is rotated in this state, peripheral air is moved by this rotation. The pressure state between the floppy disk 4 and a slider surface 3 is controlled by this air current. The disk 4 is pressed with a positive pressure on the front end side of the slider surface 3, and the disk 4 is sucked with a negative pressure in the position of the head element 16. Thus, face wobbling and oscillation of the disk 4 are suppressed, and head contact is improved because the head element 16 follows up the displacement of the disk 4 by the spring force of the gimbals 6 even at the time of displacement of the disk 4, and a small spacing loss can be set.

Title: Tail gate opening/closing device for lift-up dump truck
Inventor: KOKADO TAKANOBU
IPC: B60P1/267
Filed: 1991-09-11
Abstract: PURPOSE:To hold a tale gate in a closed condition when a load-carrying platform is lifted up or down to a chassis frame by forming a lift lock lever which comes into contact with a locking rod only when the load-carrying platform is inclined to the chassis frame to open the tail gate. CONSTITUTION:A lock arm 4 and a lift lock lever 5 are rotatably-disposed on the rear edge lower part of a load-carrying platform 2. When the load- carrying platform 2 is lifted up to a chassis frame 1, the other edge of the lock arm 4 is separated from a bolt 7, and at the same time, one edge of the lift lock lever 5 is separated from an engaging pin 9. Thus, the lift lock lever 5 is rotated by the tractive force of an extension coil spring 10, and the other edge of the lift lock lever 5 is made to come into contact with a lower surface on the other edge side of the lock arm 4. It is thus possible to maintain a condition where one edge of the lock arm 4 locks the locking pin 6, holding a tail gate 3 closed by the lock arm 4.

IPC: G21C17/003
Filed: 1992-09-29
Abstract: PURPOSE: To detect a nuclear reactor nozzle from the outside of a container by irradiating a volume to be inspected with longitudinal ultrasonic beams from two different directions, and detecting the reflections of these from a defect in the volume to be inspected. CONSTITUTION: An emission transducer 80 and a receiving converter 84 are positioned on the external surface 58 of a container near a water supplying nozzle 42, and the primary longitudinal beam 90 of the transducer 80 is derected to a volume to be inspected 60 at the curved section of the internal surface of the nozzle 42. At this time, the primary transverse beam 92 strikes the inwall 94 of the container by an angle of about 30 deg.. By this angle, almost all the energy of the beam 92 is transduced into a secondary longitudinal beam 96 and proceeds toward the volume 60. A defect 66 in the volume 60 produces a reflection 98 of a primary longitudinal beam 90, and then a reflection 99 of the secondary longitudinal beam 96. And the reflections 98, 99 are detected by the receiving transducer 84 successively.  Consequently, it becomes possible to perform inspection without gaining access into the nuclear reactor physically.
