Title: Data file equalization processing method
Inventor: TAKEDA KUNIYOSHI
IPC: G06F12/00
Filed: 1995-05-23
Abstract: PURPOSE: To surely equalize data files in a short time without damaging the performance of a dual system operation of current system and standby system at the time of starting a standby-system computer. CONSTITUTION: For example, when a computer 2 is used as the current-system computer and a computer 1 is used as the standby-system computer in a dual computer system, computers 1 and 2 of both systems asynchronously count up the update frequency counters in the unit of records and store the current- system computer discrimination information for update after a data file 221 of the current-system computer 2 is updated, and update frequency counters of computers 1 and 2 at the time of the start of the standby system or only records different by current-system computer discrimination information for update are copied from the current-system computer 2 to the standby-system computer 1.  Thus, data files are surely equalized in a short time without damaging the performance of dual system operation of the current system and the standby system at the time of starting the standby-system computer 1.

Title: Magnetic flux control circuit
Inventor: ISHIDA KOICHI
IPC: G05F7/00
Filed: 1987-05-22
Abstract: PURPOSE:To compensate an eddy current delay at a high speed by comparing a magnetic flux simulation value obtained from a simulation circuit of an electromagnet having an eddy loss with a practical value, setting up a feedback loop so as to execute the same operation as a real coil and adding a differential value of an effective current proportional to an obtained eddy current time constant to a current command value. CONSTITUTION:Magnetic flux phi is detected by a magnetic flux detector 4, a simulation circuit is formed by a multiplier 51B and an integrator 53A, a deviation (e) between an obtained magnetic flux simulation value and a practical value is extracted by an adder/subtractor 54C and multiplied by the simulation value through a multiplier 51C, and the multiplied value is integrated by an integrator 53B and inputted to the multiplier 51B. At that time, a value (a) corresponding to an eddy current time constant is obtained as the output of the integrator 53B. In said constitution, a delay due to the eddy current can be compensated without measuring and adjusting work and pulse-like magnetic flux having sharp leading and trailing edges can be formed. Even if the temperature change of a coil resistance is generated or a coil having a different time constant is used, readjustment in each change can be omitted.

IPC: H04L27/14
Filed: 1988-05-20
Abstract: PURPOSE:To reduce the quantity of hardware and to form an LCI chip by providing a control circuit which presets a complement of 2 to a criterion in a zero-cross interval measuring counter according to the detection of zero-cross points and starts measurement. CONSTITUTION:A complement of 2 to a threshold period from a memory 301 is preset in a counter 302 for each zero-cross point at the start of measurement, zero-cross intervals in one section are measured, and the threshold period is a criterion used when a binary signal is decided from the measured value of the counter. The measurement result is stored in a register 402 through a selector 401 and the contents of the register 402 are shifted to a low-order register at the same time. Then, an accumulation register is cleared and when the contents of shift registers 402-405 are circulated by one round through the selector 401, an adder sums up the outputs of the register 405 and accumulation register 407, so that the sum is stored after the contents of the registers 402-405 are shifted by one round. Consequently, the number of bits is small and the hardware quantity may be small.

Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To detect disconnection of the element wires of a parallel-wire cable that is a hanging member of a bridge, such as a cable stayed bridge or a suspension bridge, or of a construction. SOLUTION: Part of a cover 5 at a position that is 5m or so away from the end 3 of cable is peeled, an ultrasonic probe 7 is contacted with the side of an element wire 2 for examination, and ultrasonic pulses of a predetermined frequency are input to the element wire 2 by an ultrasonic flaw detector 8. The input ultrasonic pulses propagate within the element wire 2 toward a socket 3 and, if the element wire 2 is ruptured, are reflected at the rupturing point; if the element wire 2 is not ruptured, they are reflected at an element wire terminal point 3 inside the socket. The reflected pulses are detected by the ultrasonic probe 7 and converted into voltage signals by the ultrasonic flaw detector 8, and a display device 9 is used to determine whether or not there is a rupture and displays the rupturing position.  If there are no reflected waves, the element wire 2 is judged to be ruptured diagonally.

Title: Low-interference type touch panel device
Inventor: KATABAMI KOICHIRO
IPC: G06F3/03
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To improve the reliability and certainty of the device by using an absolute value detection type level measuring circuit as a circuit which measures a finger touch position and then reducing detection deviation in touch position into a problem-free range even when multiple devices are used nearby at the same time. SOLUTION: A vibration voltage applying circuit 6 supplies a passing current to its circuit ground even when not selected by an analog multplexer(MUX) 8 to always hold input characteristics under certain conditions. An AC signal current having passed through the MUX 8 is processed by current/voltage conversion, band-pass filtering, AC-signal level demodulation, etc., and applied to an A/D converter 10. From its respective digitized data, a processor (CPU) 11 calculates the position of a touch on the surface of a panel 1 with a finger of a human body 2. At this time, an absolute value detection type AC signal level demodulating circuit is not affected by the phase shift of the AC signal. Therefore, deviation in the ratio of respective signal levels is eliminated to eliminate deviation in calculated position.

Filed: 1980-09-05
Abstract: PURPOSE:To reduce the error for decoding and simplify the constitution of hardware of the high-density recording system, by converting a binary data string to a four-bit code by a prescribed algorithm. CONSTITUTION:Two-bit data is converted to a four-bit code in accordance with the algorithm of the S1 conversion table. (In the S1 conversion table, A-D are four kinds of pattern constituted by two-bit patterns, and Y is the complement logic of OR of the two-bit code just before a code Y, and En is a data bit of n bits before two-bit data in the two-bit data string, and Ln is a data bit of n bits after two-bit data similarly.) That is, in case that the binary data string is separated into every two bits and is converted to four-bit data, it is converted identically in accordance with patterns within four bits before and after a two-bit pattern to constitute a code sequence where 2-7 code 0s exist between a code 1 and the next code 1, and thus, the occurrence of errors is reduced at the decoding time, and the constitution of a high-density recording device is simplified.

IPC: B22C1/22
Filed: 1979-09-26
Abstract: PURPOSE: A binder for self-hardening molds which is obtained by cocondensating furfuryl alcohol, urea, phenol, predetermined reactant and formaldehyde and which decreases the cracks of molds.  
     CONSTITUTION: One or more kinds of compounds selected from furfuryl alcohol, urea abd phenol, the reactant of the formula of 2, 2, 4-trimethyl-4-(hydroxyphenyl) chroman and isopropenyl phenol and formaldehyde are cocondensated, There are no particular limits for the sequence of reaction. Formaldehyde is, for example, formalin or the like. For example, hydrochloric acid, ammonia, or the like is properly used for the reacting catalyst. The cocondensation is caused to take place by performing vacuum condensation at about 50W100°C reaction temperatures and about 400W700mmHg degrees of vacuum. The reactant obtained thereby relieves the rigidity of the mold by giving thermoplasticity thereto, and is effective for preventing the cracking of the mold.

Abstract: PURPOSE:To prevent the hunting of a pulse motor by controlling the revolution of the pulse motor following an input signal within an allowable speed range thereof so as to regulate it to the maximum level within the allowable range when the input signal exceeds the allowable revolution. CONSTITUTION:An input signal 22 is compared with an output of an integrating circuit 4 by means of comparators 5 and 6.
