Title: Digital signature system
Inventor: FUJIOKA ATSUSHI
IPC: G06F21/64
Filed: 1991-01-21
Abstract: PURPOSE:To decrease the throughput and communication quantity at the time of verification and to match a confirming procedure and a denial procedure. CONSTITUTION:Open information y:g<x>(mod p) generated by using pieces (p) and (g) of common information and a signature key (x) is registered in an open file at a center. A signer sends his or her signature s:m<x>(mod p) to a verifier. The verifier sends a message (m) and the signature (s) to the signer. The signer generates a communication sentence X1, dummy g<r> (mod p), and X2=m<r> (mod p) by using a random number (r) and sends them to the verifier. The verifier sends a random number (e) to the signer. The signer generates and sends a communication sentence Y:r+ex to the verifier. The verifier inspects whether Xn1.<e>:(mod p) and X2.S<e>=m<r>(mod p) hold or not and judges that (s) is the formal signature of (m).

Title: Recording medium
Inventor: OTOMA TAKASHI
IPC: B41M5/00
Filed: 1989-01-17
Abstract: PURPOSE:To reduce the cost by forming a porous oxide layer onto the surface layer of a metallic film and using the porous oxide layer as the receiving layer of ink. CONSTITUTION:Aluminum, titanium, magnetsium, etc., are exemplified as a metallic film. Porous oxide layers are shaped onto the surface layers of these films, but it is proper as the physical properties of the layers that approximately 40-500Angstrom  are adopted as the diameters of pores forming such layers. Since the rate of absorption of ink is slow and dots are spread completely when the diameters of the pores do not satisfy the range and there is the possibility of the insufficient holding characteristics of ink such as adhesion onto the hand of the ink of a printing surface, transfer onto other printing paper, etc., when the diameters exceed the range on the contrary, both cases are not preferable. Since the defective absorption of ink is generated and the effect of the color of a foundation metal is generated when the thickness of such a porous oxide layer is too thin and there is the possibility of the generation of the partial peeling of the porous layer when the thickness is too thick inversely, both cases are not favorable, and it is proper that approximately 10-50mum are adopted generally.

Filed: 1981-01-19
Abstract: PURPOSE:To control the ignition timing not to exceed upper limit temperature of an O2 sensor in engine control using the O2 sensor, by advancing an angle of the timing in accordance with engine speed and intake air quantity when exhaust temperature continuously exceeds a preset reference value by the prescribed speed (N). CONSTITUTION:When an engine is started, its speed is set to 0 in a step 30, and exhaust temperature is detected and compared with a reset reference value at every 50msec in a step 32, then 1 is added to N at each time the temperature exceeds the preset reference value. An interruption routine is started synchronously with speed of the engine. When the speed N is not less than 5, the ignition timing is controlled its angle advanced in a step 41. Further in a step 40, an advance angle is corrected in case of continuous speed N not less than 5 times when the exhaust temperature is not less than the preset reference as a result of decision, then hunting operation can be prevented to improve drivability. In this way, the exhaust temperature can be limited even in a range high loaded at high speed.
