Title: Electronic signature method by ic card
Inventor: IEGI TOSHIATSU
IPC: G06F19/00
Filed: 1990-09-07
Abstract: PURPOSE:To perform such authorization that transaction is surely performed by the owner of an IC card for user by incorporating only a deciphering key for open cryptography in the IC card for user, and only an open key in a card for verification. CONSTITUTION:Electronic signature is performed by enciphering a result in which transaction data is enciphered by the deciphering key R for open key cryptography and an open key cryptographic function RSA and furthermore, by enciphering/deciphering keys K1-Kn for secret key cryptography and a secret key cryptographic function FEALF or DES in the IC cards CD1-CDn for user. Since the enciphering/deciphering keys K1-Kn for secret key cryptography are decided at every IC card for user individually, the electronic signature of the IC cards CD1-CDn for user are set differently from each other, and since no deciphering key R for open key is incorporated in the card KM for verification, it is possible to prevent the forgery of the signature. Thereby, it is possible to authorize that the transaction is surely performed by the owner of the IC card for user perfectly.

Abstract: PURPOSE:To eliminate a power converting mechanism and a decelerating mechanism, and simplify structure by using a piezoelectric actuator for a drive source for making the main axis of a tapping machine, in which a tap processing a work piece is provided on the tip, a reciprocating linear motion. CONSTITUTION:When A.C. voltage is applied to a drive control circuit 37 connected to the electric terminal of an ultrasonic vibrator 11 pressedly fixed to the main axis 32 of a tapping machine 31 with a pressing mechanism 33, a fine vibration is excited. As a consequence, the main axis 32 is made a reciprocating motion by the friction force of the drive parts 34a and 34b of the vibrator 11 and the main axis 32. The high frequency vibration is transmitted to a tap 42 retained with a chuck 41 on the lower part of the main axis 32 to remove the cut powder of a work piece 44 on a processing base 43. The rotation of a rotation motor 40 is transmitted to the main axis 32 via a belt 39 to make a tapped hole processing. This removes the cut powder by the vibration of a piezoelectric actuator to permit the shortening of a processing time.

IPC: F25B1/00
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To surely prevent a return of liquid from gas injection piping by a reliable and simple construction. SOLUTION: A control valve 6 provided for gas injection piping 5 and controlling the amount of injection of gas refrigerant is constituted of a temperature type expansion valve and a temperature-sensitive tube 68 of this temperature type expansion valve is disposed at a position located on the gas injection piping 5 and in the vicinity of a compressor 1 where it is subjected to a thermal effect of the compressor.

Abstract: PROBLEM TO BE SOLVED: To reduce the threshold voltage of a semiconductor element and to improve the leak current characteristic and the degree of integration of the element, by forming first and second transistors on one active area in a laminated structure so that the transistors can share the use of one gate electrode. SOLUTION: First and second transistors 100 and 200 are formed on one active area 11 in a laminated structure. The transistors 100 and 200 share the use of one gate electrode 14a. First metallic wiring 40 is formed in such a way that the gate electrode 14a shared by the transistors 100 and 200 is electrically connected to the drain area 28 of the second transistor 200. Second metallic wiring 42 is formed in such a way that the active area 11 is electrically connected to the source area 26 of the second transistor 200. Since the transistor 100 and 200 are formed on one active area 11 in such a way in a semiconductor element, the degree of integration of the element is improved remarkably. In addition, since the semiconductor element has a low threshold voltage and causes less leak currents, the element can be suitably used for portable electronic products.

Title: Substrate holding device
Inventor: ITABANE MASAYUKI
IPC: B23B31/10
Filed: 1993-08-31
Abstract: PURPOSE:To prevent a substrate from slipping at the initial period of the acceleration of a rotation and at the final period of its deceleration. CONSTITUTION:A substrate W is held on a horizontal rotating stand. A pendulum- shaped pressure member 11 which can be freely rotatable and movable inside a nonvertical face is installed at the outer edge side of the rotating stand. When the rotation of the rotary stand is accelerated and decelerated, the pressure member 11 is turned and moved in such a way that the center of gravity of the pressure member 11 is brought close to the back Rd and the front Fd in the direction of the rotation by the action of an inertial force. As a result, the pressure member 11 comes into contact with, pressed and energizes, a substrate outer edge Wa, and it is possible to prevent the wafer W from slipping. On the other hand, during a period the substrate is turned at high speed and at constant speed, the inertial force does not act, and the center of gravity of the pressure member 11 is situated at the outside Rd in the redial direction of the rotation. As a result, the pressure member 11 escapes from a contact state with the substrate outer edge Wa, and it releases the substrate outer edge Wa. Thereby, it is possible to prevent the substrate from slipping at the initial period of the acceleration of the rotation and at the final period of its' deceleration, and there is no fear that an excessive constraint force is added to the substrate due to a centrifugal force generated in a high-speed rotation.
