Title: Method for storing and managing secret key
Inventor: SHIYOUJI NAGAYOSHI
IPC: G09C1/00
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To disable a theft or illegal use of a secret key by devising a method such that the secret key cannot be decoded by the pass phrase of a user only and a remaining part of a decoding key is not in existence around the user SOLUTION: When the user uses a secret key, the user inputs the pass phrase to its own computer and uses a public key of an opposite party to cipher a text and sends the resulting text. The opposite party receiving it returns a random number having received and stored at the end of a preceding communication. The user synthesizes a 1st scramble key from the both to decode the stored secret key and to acquire the secret key not ciphered. The user computer generates a 2nd random number and a 2nd scramble key based on it and the pass phrase, ciphers again the secret key and stores the result. Furthermore, the 2nd random number is ciphered and sent for the use of the succeeding communication and it is deleted with the 2nd scramble key from its own computer. Thus, every time a secret key, it is stored while being changed into another form.

Title: Hydraulic shock absorber
Inventor: MATSUDA TOSHIYO
IPC: F16F9/344
Filed: 1981-01-30
Abstract: PURPOSE:To keep comfortable driving by a method wherein a hydraulic shock absorber is used in a chassis suspension for an automobile and the like, the inner capacity in a piston is kept large in such a manner as a piston rod is not placed in a hollow interior of the piston rod, and it may be operated in a specified proportional relation even if a piston speed at a pushing stroke is at a high speed. CONSTITUTION:When a piston 2 is compressed in a lower oil chamber A, a valve body 6c is moved upwardly against a spring 6b under a hydraulic pressure in a lower oil chamber A, the oil in the lower oil chamber A is flowed into an upper oil chamber B through an oil groove 9 and oil hole 3 along a line indicated by a solid arrow. During this process, the dampening force is generated. When the pushing piston speed is increased and a volume of oil passing through the oil groove 9 becomes larger than an allowable volume of passing through the oil hole 3, a hydraulic pressure in the hollow interior of the piston 5 becomes high, the ball 8a in the oil passage 7 is pushed against the spring 8b, the oil is passed through a space between the ball 8a and the oil passage 7, and then pushed into the upper oil chamber B along the dotted line of arrow. Thus, it is possible to keep a specified rate of increasing dampening rate.
