Title: Cryptographic key generating system
Inventor: OTA KAZUO
IPC: H04L9/30
Filed: 1989-07-28
Abstract: PURPOSE:To reduce processing quantity for decoding by specifying a generating method for a ciphering key and a deciphering key in an RSA open key code. CONSTITUTION:The key generating mechanism of an RSA signal consists of a prime number generation part 100, a greatest common divisor(GCD) calculation part 200, a secret key generation part 300, a simultaneous equations solution part 400, an LCM calculation part 500, an inverse number calculation part 600, and a multiplication part 700. At the time of the generation of the cryptographic key of an RSA code, two prime numbers P, Q are generated, and the deciphering key (d) is selected so that power calculation can be executed at a high speed by using directly the prime numbers P and Q, and the ciphering key (e) corresponding to the deciphering key (d) is calculated, and the deciphering key (d) is made secret, and the ciphering key (e) and product N(=PXQ) are opened to the public. Thus, the processing quantity for the deciphering can be reduced.

When a panel is placed on the die face of the die 1 and the punch 2 is lowered while  pressing the rim of the panel by a blank holder, the panel is drawn slowly. A  part of the panel is pressed strongly by the rubber 10 at a point just before the  bottom dead center of the punch 2, and gradually drawn int the hole 12. By this  way, flowing in of the excess metal into the product domain is prevented, and accordingly, generation of wrinkles can be prevented.

Title: Automatic disk player
Inventor: KENMOCHI ISAMI
IPC: G11B3/085
Filed: 1982-11-10
Abstract: PURPOSE:To reduce the cost of a disk presence discriminating mechanism and the overall cost of an automatic disk player by forming said mechanism with a pure mechanical structure. CONSTITUTION:When a slide plate 93 slides, a reset plate 147 oscillates. In response to this oscillation of the plate 147, a detection plate 86 oscillates. Then a hook part 87 of the plate 86 moves to a hooking position with a hook part 82 of a disk mounting detection pin 80 provided to a turntable 6. When no disk 16 exists, the part 82 is set at a lower position and hooks the part 87 to give pressure. Therefore the plate 86 oscillates and hooks an intermediate lever 102. In this case, the plate 147 has no oscillation. When the plate 93 slides further, the lever 102 hooks the plate 86 and a relay lever 108 respectively. Thus the lever 108 oscillates to move a control plate 113. Then the hook is released between a hook 131 and a switch locker 220, and both the hook 131 and a latch stopper 129 have oscillations. Thus a pickup plate 123 oscillates, and therefore a lead-in action is prevented.
