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.

A malicious-module identification device identifies and deactivates a malicious module operating in an information processing device connected thereto via a network. The malicious-module identification device is provided with a reception unit for receiving results of tampering detection from a plurality of modules for detecting tampering, and a determination unit 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. A deactivation unit outputs an instruction to deactivate the module identified as the malicious module.

An update server acquires, from an apparatus, a result of verifications relating to tampering of a protection control module and each of install modules included in an install module group. The update server determines a processing procedure of the apparatus depending on the acquired result of the verifications. Specifically, if it is judged that the protection control module and each of the install modules is unauthentic, then the update server transmits, to the apparatus, an instruction to perform updating of the unauthentic protection control module in preference to a revocation of the unauthentic install module.

A gaseous constituent supply device supplies an air cannon projectile containing a predetermined gaseous constituent to an occupant in a compartment of a vehicle. This supply device includes a gaseous constituent supply chamber for reserving the gaseous constituent, an air compression unit for compressing an inside of the gaseous constituent supply chamber to generate an air cannon projectile including the gaseous constituent and to emit the air cannon projectile to an individual occupant, and a control unit that estimates an airflow state in the compartment and controls operation of the air compression means based on the estimated airflow state.

A vehicular lamp having a distance adjustment section that adjusts the distance between the lamp body and the reflector and includes an adjustment shaft, a gear member, and a receiving element. The adjustment shaft has a spherical end; the gear member includes a shaft portion that has the adjustment shaft therein, elastic pawls protruding from the shaft portion, and empty spaces defined by the elastic pawls to allow flexure of the elastic pawls toward the shaft portion; and the receiving element is formed on the back surface of the reflector. The gear member having the adjustment shaft is rotatably inserted in an insertion hole of the lamp body, the elastic pawls are engaged with the edge of the insertion hole to prevent the gear member from slipping out; and the spherical end of the adjustment shaft is engaged with the receiving element and prevented from rotating.
摘要:
The mean grain size (D2) of the main crystal phase 11 in the external cover dielectric layers 3 is made larger than the mean grain size (D1) of the main crystal phase 11 in the dielectric ceramic layers 7, and the amount of the secondary phase (M2) in the external cover dielectric layer 3 is made more than the amount of the secondary phase (M1) in the dielectric ceramic layer 7, or the volume proportion of the secondary phase 16 to the main crystal phase 11 in the external cover dielectric layer 3 is made lower than the volume proportion of the secondary phase 16 to the main crystal phase 11 in the dielectric ceramic layer 7. This constitution produces the multilayer ceramic capacitor having a large number of thin layers stacked one on another that is capable of suppressing the occurrence of delamination between the external cover dielectric layers and the effective dielectric material section and between the effective dielectric material sections due to the difference in shrinkage by firing even when particle size of the dielectric material powder is made smaller.

A vehicle air conditioner includes a blower for blowing air into a space of a vehicle compartment, and an air-conditioning mode switching portion for switching between air conditioning modes. The air conditioning modes include a normal air conditioning mode in which air conditioning of a specific region including a driver seat and air conditioning of a non-specific region not including the specific region in the space of the vehicle compartment are performed, and a specific-region prioritizing air conditioning mode in which an air conditioning capability for the non-specific region is decreased as compared to the normal air conditioning mode. The air-conditioning mode switching portion adjusts the air conditioning capability for the non-specific region based on a pressure of air drawn into the blower, in the specific-region prioritizing air conditioning mode.
