摘要:
An encryption processor for encrypting and decrypting data that ensures data security by preventing illegal deciphering or leakage of the data. The encryption processor includes a CPU for running a program, a ROM for storing the program run by the CPU, a RAM used as a work area while the CPU is running the program, an I/O section for sending/receiving data to/from an external device, and an encryption section for decrypting encrypted data and encrypting plain text data.

The present invention relates to a device connection state recognizing method capable of recognizing a connection state of devices without addition of signal lines dedicated to detection. Thus, in the method according to this invention, a portion of or all of a plurality of data signal lines are connected through pull-up resistors to a high electric potential or connected through pull-down resistors to a low electric potential in accordance with the connection state of the devices, and a processing unit reads, as structure information data, a high electric potential state/low electric potential state generated by the pull-up resistor/pull-down resistor in the portion of or all the plurality of data signal lines to recognize the connection state of the devices on the basis of the read structure information data. This invention is applicable to a various types of processing units which are to be connected through a common data bus to a plurality of devices.

An integrated unit for producing double-layered spherical products (23) in two rows on a belt conveyor (25) under it is disclosed. The length of the integrated unit is aligned with the traveling direction of the conveyor (25) in order to reduce the space needed on both sides of the conveyor (25). The integrated unit includes a filling feeder (15) and a casing feeder (17) for feeding a filling (5) and a casing (9) such that the feeders (15) and (17) are arranged opposite each other. A space between the feeders (15) and (17) of the integrated unit is provided with vane pumps (29A) and (29B) and a pair of double nozzles (13A) and (13B), which are positioned in the center of the integrated unit. The vane pumps (29A) and (29B) pump the corresponding materials (5) and (9) from the corresponding feeders (15) and (17) to the corresponding double nozzles (13A) and (13B). Each double nozzle extrudes the filling (5) and the casing (9) in a form of a double-layered elongated product. The integrated unit also includes a pair of cutting mechanisms (21) for cutting the elongated product into a plurality of double-layered spherical products (23), and for dropping them on the conveyor (25) in two rows.
摘要:
A method of communication between an adapter and a drive improves the data processing efficiency of the adapter and data transfer efficiency between the adapter and the drive.The drive has a slot to receive a disk cartridge containing a disk and drives the cartridge. The adapter is shaped to be inserted into the slot of the drive. The adapter has a controller to transfer data between the adapter and the drive through the heads thereof. The controller formats data so that the formatted data may fit into at least part of a disk format having tracks and sectors handled by the drive. The controller assigns a specific one of the tracks to the formatted data and transmits the track with the data to the drive.

A disk-cartridge-type adapter is capable of reducing power consumption.The adapter has a sensor for detecting the rotation its of a motor of a drive into which the adapter is inserted. If the sensor detects that a magnet (101) attached to a spindle of the motor is not running, power from a power source of the adapter is supplied only to an MPU of the adapter and is not supplied to an interface with the drive.
摘要:
An interrupt control system in which a main process device executes an interrupt process, having a high process priority. The process priority is registered in a table, corresponding to each interrupt generating source, and an intermediate process device receives an interrupt signal from each interrupt generating source, obtains the corresponding process priority from the table and informs the main process device of the interruption. Accordingly, the process priority can be easily changed, and the system has a small size because the interrupt circuit for the main process device is centralized.
摘要:
An objective lens of large relative aperture comprising, from front to rear, a first lens component of positive power, a second lens component of positive power and a third lens component of negative power, the first and third lens components being moved forward as a unit, while the second lens component is simultaneously moved forward by a smaller amount than that of the movement of them to effect focusing from infinity to shorter object distances. The focal lengths of the first, second and third lens components, the calculations of the constituent lenses, and the glass materials of which the lenses are made up are properly chosen so as to achieve a high grade imaging performance throughout a focusing range from infinity to very short object distances.
