摘要:
The present invention provides a process for producing a molten glass which can produce a molten glass having a good quality, a glass-melting furnace, a process for producing glass products and an apparatus for producing glass products.While an oxygen combustion burner 20 is rotated by a motor 38, glass raw material particles (not shown) are dropped into a high-temperature gas phase atmosphere produced by a flame F of the oxygen combustion burner 20, to be changed into liquid glass particles. By rotation of an outlet (nozzle) of the oxygen combustion burner 20, the falling position of the liquid glass particles 26, changes with time. Accordingly, generation of bubbles caused by continuous fall of the liquid glass particles in a particular position on a molten glass liquid surface is prevented. Accordingly, it is possible to produce a molten glass having a good quality with few bubbles.

摘要:
In a data encryption/decryption method including an encryption step and a decryption step. In the encryption step, there are prepared n pairs of secret keys and public keys in a public-key cryptographic scheme, where n is a positive integer. A new key is generated in accordance with at least one of the public keys. Data is encrypted in a common-key cryptographic scheme by use of the new key. There is prepared a (k,n) threshold logic (k is an integer equal to or less than n) having terms associated with the new key and the n public keys. A calculation of the threshold logic is conducted by use of the new key and the n public keys, and encrypted data and a result of the calculation of the threshold logic are stored. In the decryption step, the new key is restored from k secret keys selected from the n secret keys and the stored result of the threshold logic calculation in accordance with a threshold reverse logic corresponding to the threshold logic and stored data is decrypted by the restored key in the common-key cryptographic scheme.
摘要:
In an IC card incorporating residual multiplier hardware for implementing a high-speed algorithm for a residual multiplication arithmetic, a method and a device capable of executing public key encryption processing such as an elliptic curve encryption processing at a high speed. Residual arithmetic succeeding to generation of a random number and residual arithmetic in a signature generating processing can be executed by using a residual multiplier. Further, in order to use effectively the residual multiplier for arithmetic operation on an elliptic curve, the point on the elliptic curve is transformed from a two-dimensional affine coordinate system to a three-dimensional coordinate system. Additionally, multiplicative inverse arithmetic for realizing reverse transformation from the three-dimensional coordinate system to the two-dimensional affine coordinate system as well as for determining a signature s can be executed only with the residual multiplication arithmetic. By making use of the residual multiplier in this manner, the processing speed can be increased. Computation complexity can be reduced by storing previously those parameters which are used frequently and constant multiplies of a base point of the elliptic curve in the form of tables, which also contributes to increasing of processing speed.
摘要:
Alignment between a mask and a photosensitive substrate is performed using a first reference mark formed on the mask and a second reference mark formed on the photosensitive substrate. After that, the mask and the photosensitive substrate are relatively moved, so that an image of one of a light-shielding pattern and a light-transmitting pattern formed at a position different from the first reference mark on the mask is formed on the second reference mark on the photosensitive substrate. Then, a circuit pattern formed on the mask is transferred onto the photosensitive substrate, and a partial region including the second reference mark is exposed with the image of one of the light-shielding pattern and the light-transmitting pattern.

摘要:
The present invention is directed to scanning exposure apparatus and exposure method to achieve simultaneous projection of images of plural regions on a mask onto a photosensitive substrate with correcting an orthogonality error of a pattern on the mask or photosensitive substrate. If the pattern on the mask or photosensitive substrate has an orthogonality error causing a deviation of a certain angle in a first direction perpendicular to a scanning direction as it goes in the scanning direction, the mask and the photosensitive substrate are rotated relative to each other in the plane thereof to align one coordinate axis in a coordinate system of each pattern with the first direction. Then a relative displacement is given by an amount of the orthogonality error between positions of images projected through a first optical system and positions of images projected through a second optical system, and relative positions of the mask and the photosensitive substrate are continuously changed by the amount of the orthogonality error in the first direction in accordance with the position of the mask or photosensitive substrate in the scanning direction.
