Abstract: PROBLEM TO BE SOLVED: To prevent a case where information of high confidentially that is recorded on an IC card is read by a third person, and accordingly to prevent the lowering of security of the IC card. SOLUTION: An IC card R/W 13 enciphers the original data 3 into a code X by a cipher function g and a key kg, generates random numbers r1 and r2 by a random number r1 generation part 15 and a random number r2 generation part 17 respectively, adds the numbers r1 and r2 to the code X and enciphers the added code X by a key Kf and a cipher function f to send it to an IC card 5 as an authentication command. A card 5 decodes the received authentication command by the key Kf and the function f and takes out the code X and numbers r1 and r2. A measuring device 23 reads the authentication object information out of an optical mark hologram 7. Then the code X is collated with the authentication object information by a collation algorithm 21. When the coincidence f the collation is confirmed, the number r1 is enciphered by the function f and the key Kf.

Title: Misfire detecting device for internal combustion engine
Inventor: MATSUMOTO TAKUYA
IPC: F02P17/12
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To surely detect misfiring by using a larger one of status values of crank rotation of first and second engine cylinders which are adjacent to each other in the firing order, as a crank rotating status value so as to determine misfiring of a predetermined engine cylinder of an engine in accordance with a variation in the crank rotating status value. SOLUTION: During operation of an engine 1, an ECU 30 successively computes a desired time of rotation of a crank shaft 23 for an n-th engine cylinder in a misfiring judging zone in accordance with a crank angle signal from a crank angle sensor 24. Further, it computes an averaged angular speed corresponding to the n-th engine cylinder from the desired rotation time, and stores the same in memory. Whether the present averaged angular speed is greater than the previous value is determined, and if it is true, the present value is substituted for the previous value, but it is false, the previous value is directly used. That is, the larger one of the present value and the previous value is selected, and is regarded as the previous value of the averaged angular speed.  If the previous value is lower than a misfiring determination threshold value, it is determined that a n-1-th engine cylinder misfires.

Title: Instrument for localizing faulty insulation point of cable using constant-voltage ic element
Inventor: ABE TOSHINORI
IPC: G01R31/08
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To easily localize the faulty insulation point of a defectively insulated cable in a short time without using any defectless conductor by making a constant current to flow from the starting ends of a plurality of conductors of the cable and detecting the point at which the distributed voltage of the conductor loop becomes the minimum. SOLUTION: At a measurement starting point A, a constant current is made to flow to conductors L2 and L3 from the constant-voltage circuit 5 of an measuring instrument 1 in the opposite polarity and, at a measurement ending point B, a constant current is made to flow to defective conductors L2' and L3' from the constant-voltage circuit 6 of another measuring instrument 2. At the point B, the constant current from the point A is made to pass through by short-circuiting the conductors L2' and L2' with each other. A very low voltage detecting circuit 3 detects the point at which the currents flowing to the insulation resistances R1-R3 of defective conductors L1-L3 connected to resistors r1 and r2 incorporated in the circuit 3 are balanced and become the minimum.  When the output of the instrument 1 is gradually lowered, the output from the point B automatically increases and a loop current is maintained at a constant value. Consequently, a faulty point caused by defective insulation can be calculated from the voltage drop across the conductors L2 and L3 at the point A.

Title: Time-interval measuring circuit
Inventor: NIKORASU JIYON HANTAA
IPC: G04F10/04
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To count the time interval before completing a cycle accurately by applying an output pulse to a counter means in response to the level of input signal and an output pulse signal from a ring oscillator and indicating that transition of the input signal from enable signal level is made before or after transition at the level of output signal pulse from a ring oscillator. SOLUTION: At the end of input signal pulse, enable logic signal level is removed from a synchronous circuit 3 and an error detection circuit 6 and then the state of a ring oscillator 1 is regulated and latched in a latch 7. Consequently, a 'rough' value of time interval to be measured can be obtained from the count of a counter 2 and a 'fine' value of the synchronous fraction of oscillator 1 is obtained from the latch 7 using a reference correction table. Consequently, an accurate count can be obtained even when the time interval expires upon completion of the cycle of ring oscillator.
