Abstract: A system is provided which manages the copyright of a plurality of data in a database. A data copyright management system is provided in which a primary user edits data which he or she obtains and supplies edited data to a secondary user. 
   In a case where new data is produced by editing a plurality of encrypted data obtained from the database, and is encrypted for distribution to another person, crypt keys for a plurality of data as raw material and an edition program which is an editing process with a digital signature are used as a use permit key. When a user who receives the edited and encrypted data requests use of the data by presenting the digital signature to a copyright management center, the copyright management center identifies the editor by the digital signature, and provides the user requiring use of data with the crypt key for use only when the editor is identified to be the valid user of the edited data. The system comprises a database and a key control center, and uses a primary copyright label, a first use permit key including a first crypt key, a second use permit key, a third crypt key, and a copyright management program. The primary user uses primary copyrighted data encrypted by using the first crypt key and supplied, by decrypting it with the first use permit key obtained from the key control center. The data is encrypted again by using the first use permit key when it is stored. The primary user edits the primary copyrighted data by obtaining a second use permit key from the key control center for editing the primary copyrighted data. The data being edited is encrypted and stored by using the second use permit key. At the completion of the editing, the primary user receives the third crypt key for secondary copyright as secondary exploitation right, encrypts the edited data with the third crypt key, and distributes it to a secondary user. The secondary user obtains the third crypt key and uses the edited data. 
     In another system, in a case where a new data is produced by editing a plurality of data obtained from the database, and encrypted for distribution to another person, crypt keys for a plurality of data as raw material and an edition program which is as an editing process with a digital signature are used as a use permit key. When a user who receives the edited and encrypted data requests use of the data by presenting the digital signature to a copyright management center, the copyright management center identifies the editor by the digital signature, and provides the user requiring data use with a crypt key for use only when the editor is identified to be the valid user of the edited data.

Abstract: The disclosed apparatus implements a method of joining two sheets of heat transfer paper into a single sheet almost twice as wide for use in heat transfer printing of extra wide cloth. The paper is withdrawn from source rolls (10,12) and passed along first and second respective web paths (14,16) with a very slight overlap between the papers. A glue station (30,31) applies a speed controlled amount of glue to the overlap region of one paper and the edges of the paper are brought together in the desired overlapping relationship. The thus joined paper (40) is passed through compression rollers (54,56) and wound onto a resilient rewind roll (42). Edge sensors (26,28) in each of the web paths maintain the overlap alignment of the paper paths and tension sensors (22,24) in each of the paths maintain a desired level of tension. A video camera imaging system (50,52) provides the operator with periodic video images of a magnified region of the overlap so that proper registration between the patterns on the respective papers can be maintained. Should the pattern lose registration, the operator can pulse a brake on one of the source rolls (10,12) which has the effect of quickly moving the paper back into alignment.

Abstract: An internal voltage generating circuit for generating an internal voltage VINT
from an input external voltage (VEXT) is provided to stabilize the internal voltage. When
the external voltage (VEXT) is less than or equal to a first boundary voltage (VT1) or a
second boundary voltage (VT2 (> VT1)), a constant voltage (VINTN) independent on the
external voltage (VEXT), which is produced by a constant voltage generator is outputted
therefrom. When the external voltage (VEXT) is greater than or equal to the first
boundary voltage (VT1) or the second boundary voltage (VT2), a variable voltage (>
VINTN) linearly increased with an increase in (VEXT), which is produced by a variable
voltage generator, is outputted therefrom. When a detecting means detects that the
external voltage (VEXT) has been increased to (VT2) or higher, the characteristic of the
internal voltage is switched from a constant voltage characteristic to a variable voltage
characteristic. On the other hand, when the detecting means detects that the external
voltage (VEXT) has been reduced to (VT1) or lower, the characteristic of the internal voltage
is changed from the variable voltage characteristic to the constant voltage characteristic.

Abstract: A preignition detecting method which prevents preignition (PI) from being misjudged as having occurred when an ignition plug is fouling. It is determined whether or not the ignition plug fouls in accordance with a voltage, developed across a detecting resistor which is fetched into a microcomputer 18 at a relatively early timing after an ignition command signal is outputted from an ignition device. Further it is determined whether or not preignition occurs in accordance with another voltage fetched at a relatively late timing after the ignition command signal is outputted. When it is determined that the ignition plug is fouling, it is inhibited to fetch the another voltage at a relatively late timing to prevent a misjudgment that preignition occurs due to a leakage current from being caused though preignition does not actually occur.

Abstract: Downstream and upstream signals in a transmission system are attenuated by different
amounts to allow upstream signals to be originated at individual subscribers (22-22, 30-30 )
at the same level yet be received at a common upstream amplifier ( 19b) at substantially the
same level. Different attenuation of downstream and upstream signals is achieved by the
combination of a pair of directional couplers (110a and 110b) and a diplex filter ( 132). The
couplers and diplex filter collectively separate a downstream signal destined for the
subscriber from an upstream signal generated by the subscriber. The upstream signal which
is separated may be attenuated by a matching loss element ( 138) to attenuate the upstream
signal by an amount greater or less than the downstream signal.

Abstract: A method for generating system passwords derived from an external encryption
algorithm and plain text user passwords entered during a secure power-on procedure. At
some point during the secure power-up procedure, the computer system checks for the
presence of an external token or smart card that is coupled to the computer through
specialized hardware. The token or smart card is used to store an encryption algorithm
furnished with an encryption key that is unique or of limited production. Following
detection of the external token, the computer user is required to enter a user password.
The user password is encrypted using the encryption algorithm contained in the external
token, thereby creating a system password. The system password is then compared to a
value stored in secure memory. If the two values match, the power-on sequence is
completed and the user is allowed access to the computer system or individually secured
resources. The two-piece nature of the authorization process requires the presence of both
the user password and the external token in order to generate the system password.
