Title: Ciphered communication method
Inventor: YAMADA TOMOHIRO
IPC: H04N1/00
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent the leakage of message within a computer network even when a receiving telephone network terminal is a normal facsimile equipment by allowing a call originating computer terminal to encipher a message through the use of an intermediate equipment and key information and communicating between the intermediate equipment and a telephone network terminal without nonciphering. SOLUTION: A call originating computer 15 using an electronic mail device 21 acquires the open key of the intermediate equipment necessary for ciphering in advance and stores it in an information storing means 22. At the time of transmitting a message, the mail input means of a device 21 prepares a message and a ciphering means 23 ciphers it through the use of the open key of the equipment 13 stored in the storing means 22. The ciphered message is transmitted to the equipment 13 through the computer network by a communication control means 24. As the message is transmitted after ciphering the message is prevented form being leaded within the network.

Filed: 1984-03-16
Abstract: PURPOSE:To secure easily optimum fixing conditions for plural process speeds by providing a switching means which switches the active load of pressuring elastic member in accordance with a selected process speed. CONSTITUTION:One end of a pressuring spring 4 as the pressuring elastic member is engaged with a pin 6 of a rotary solenoid 5 as the switching means which is turned in accordance with process speeds. If two kinds of process speed, namely, a low speed and a high speed are prepared, the rotary solenoid 5 is so turned that the pin 6 is placed in a position A in case of the low speed and is placed in a position B in case of the high speed. Concretely, the position A is more distant from a heat fixing roll 1 and is closer to a pressuring lever 3 than the position B. In this constituion, the rotary solenoid 5 is turned clockwise and the pin 6 is placed in the position B as shown by long and short dash alternating lines when the process speed is high. Thus, the quantity of deformation in an outside peripheral rubber part of a pressuring roll 2 is increased, and the nip width is extended, and the fixing time is extended, and therefore, good fixing is performed even in case of the high speed.
