An information security apparatus includes a plurality of monitoring modules that monitor for tampering. A management apparatus includes a reception unit that receives a plurality of monitoring results each generated by a source monitoring module monitoring a target monitoring module; a detection unit that detects an abnormality by referring to fewer than all of the received monitoring results; and an identification unit that identifies, when an abnormality is detected, a monitoring module that has been tampered with from among (i) a monitoring module that generates a monitoring result related to the abnormality, and (ii) one or more monitoring modules identified by tracing back through a chain of monitoring modules consecutively from the target of monitoring to the source of monitoring, starting from the monitoring module that generates the monitoring result related to the abnormality.

A malicious-module identification device (200a) identifies and deactivates a malicious module operating in an information processing device (100a) connected thereto via a network. The malicious-module identification device is provided with a reception unit (2310) for receiving results of tampering detection from a plurality of modules for detecting tampering, a determination unit (210a) for assuming that a module among the plurality of modules is a normal module, determining, based on the assumption, whether a contradiction occurs in the received results of tampering detection, and identifying the module assumed to be a normal module as a malicious module when determining that a contradiction occurs, and a deactivation unit (2320) for outputting an instruction to deactivate the module identified as the malicious module.

A holding device for use in assembling mechanical members comprises a joint head having a spherical head and a fastener formed continuous with the spherical head; and a clip having a joint cavity member formed of an elastic material, the joint cavity member having a groove portion having a cross-section corresponding in shape to an external shape of the spherical head, and receiving lip portions formed continuous with the groove portion, the receiving lip portions spreading outward, and a fastener formed continuous with the joint cavity member. The spherical head of the joint can be fitted in the groove portion to be held therein, whereby a member which is fastened to the fastener of the joint head and a member which is fastened to the fastener of the clip can be preliminarily held to each other. The invention provides the preliminarily-holding device for use in assembling mechanical members, which is capable of causing a part (e.g. a bumper of an automotive vehicle) having destortion in its formed shape to be preliminarily held onto a body (e.g. of the vehicle) having dimensional or positional errors in assembly, while absorbing deviations in the positional relationship between the part and body to be assembled.
摘要:
A method for removing hydrogen chloride from an exhaust gas discharged from an incinerator, which comprises the steps of: causing hydrogen chloride contained in an exhaust gas discharged from an incinerator to react with slaked lime in slurry to form basic calcium chloride; detecting a concentration (y) of hydrogen chloride remaining in the exhaust gas after the reaction with slaked lime; determining a deviation (.DELTA.y) of the thus detected concentration (y) of hydrogen chloride from a target concentration (y.sub.o) thereof; determining a corrected deviation (.DELTA.y') by adding to the above-mentioned deviation (.DELTA.y) a correction value (.DELTA.y.sub.1) calculated in accordance with the following formulae:.DELTA.y.sub.1 =-G.sub. p(S)(1-e.sup.- LS)U (1).DELTA.y'=.DELTA.y+.DELTA.y.sub.1 (2)where,G.sub.p (S): a transfer function representing a first order lag,e.sup.-i LS : a transfer function representing a dead time, andU: a target amount of supply of slaked lime, which renders the deviation (.DELTA.y) zero;determining a target amount of supply (U) of slaked lime, which renders the thus determined corrected deviation (.DELTA.y') zero; and adjusting an amount of supply of slaked lime so that the amount of supply of slaked lime agrees with the thus determined target amount of supply (U) of slaked lime; thereby removing hydrogen chloride from the exhaust gas discharged from the incinerator.
摘要:
A device for connecting pivotally two yoke members of a windshield wiper. Each yoke member has a cross-section including two generally vertical side walls and a top wall connecting the upper ends of the side walls, and the yoke members are overlappingly disposed relative to each other. The device comprises a pivot pin passing through aligned openings in the side walls of the two yoke members, and the pivot pin is divided into plural portions in the cross-section thereof at the location inner side of the side walls of inner yoke member, with the plural portions being separated from one another in the radially outward directions thereby forming a large diameter portion.
摘要:
To aim provide a software update apparatus including an install module group (130) composed of a plurality of install modules. Each of the install modules has a function of receiving, from an external server (200), a replacement protection control module (121) to be used for updating a protection control module (120) having a function of verifying whether a predetermined application has been tampered with. Each of the install modules simultaneously running is verified by at least another one of the install modules simultaneously running, as to whether the install module has a possibility of performing malicious operations. If any of the install modules is verified as having the possibility of performing the malicious operations, any another one of the install modules that is verified as not having the possibility revokes the any install module verified as having the possibility.
摘要:
A management device detects whether any normal monitoring module that has not been tampered with exists by referring to monitoring results received from an information security device and selects, when existence is detected, one of the monitoring modules and assumes that the selected monitoring module has been tampered with. The monitoring device then successively applies a procedure to monitoring modules other than the selected monitoring module by referring to the monitoring results, starting from the selected monitoring module, the procedure being to assume that any monitoring module determining that a monitoring module assumed to have been tampered with is normal has also been tampered with. As a result of the procedure, when all of the monitoring modules are assumed to have been tampered with the management device determines the selected monitoring module to be a normal monitoring module that has not been tampered with.

摘要:
Resistor compositions for producing a resistor for use in resistor-incorporated spark plugs and comprising a glass, an inorganic aggregate, and carbon black and/or a carbonaceous substance as a regulating agent for resistance value, with or without a stabilizing agent for resistance under load of the resistor, are now modified by addition of a reducing metallic powder such as powder of Al, Mg, Zn, Sn, Ti, Zr, Fe, Ga and Ag or alloys thereof, to improve the service life characteristics under load of the resistor. Such compositions are further modified by additional presence of a ceramic aggregate of a particle size of 100 to 800 .mu.m, to improve the electric wave noise-preventing property.
