Abstract: A call control device including: a memory, and a processor coupled to the memory and configured to: receive a call request from a communication device, a source of the call request being a terminal, the call request being transferred by the communication device when the terminal is registered in a management device, and request the management device to deregister the terminal when the call control device is determined that the call control device is attacked from the terminal based on the call request.

Abstract: A dividing unit sets an actual packet length transferred from a packet receiving section to a variable U, and then sets 2? to a variable V. If a positive number determining section determines that a subtraction result of subtracting a remainder N0 from a quotient M0, both found by dividing U by V, is a positive number, the dividing unit overwrites the subtraction result to U. The dividing unit repeats such operations of dividing the subtraction result by V, until the positive number determining section determines that the subtraction result of subtracting the remainder from the quotient, both found by dividing U by V, is a non-positive number. When the subtraction result becomes a non-positive number and the quotient and the remainder match, a packet length determining section determines that received data has a normal size, and notifies it to a discard determining section.

Abstract: A method for accessing shared memory cards from each of plural processor cards is disclosed. The shared memory cards are composed of a shared memory card of an operating system and a shared memory card of a standby system in a redundant configuration, and each of plural processor cards individually access the shared memory cards. Each of the plural processor cards is connected to the shared memory card of the operating system and the shared memory card of the standby system in a point-to-point structure via corresponding serial buses and executes data transmission on a one to one basis to/from the shared memory card of the operating system and the shared memory card of the standby system.

Abstract: An evaluation method and printer in which a maintenance man may easily identify a deteriorated component in addition to a component that is broken down or is remarkably hard to operate without the need for any additional complex detecting device. A printer has a control part which controls a mechanical part and judges quantitatively in which state among normal, deteriorated, and abnormal states each mechanical part component is located. This judgment will change in accordance with whether the printer is in a maintenance or a normal mode. Further, a deteriorated component can be determined by visually inspecting a copy after one or a combination of electric parameters have been set to printable upper and lower limits.

Abstract: An isolated gene encoding an esterase capable of asymmetrically hydrolysing an ester of chrysanthemic acid or its derivative to give an intermediate useful for the production of pharmaceutically and/or agriculturally useful compounds, expression plasmids containing said gene, microorganisms transformed with said expression plasmids, and the production of the esterase by culturing said transformants.
