摘要:
A vehicle authentication device has an in-vehicle device mounted on a vehicle, an authentication unit disposed in the in-vehicle device, for matching an ID returned from a portable device in response to a request from the in-vehicle device and performing an authentication of the vehicle, and an operation switch for instructing a power supply transition of the vehicle. The in-vehicle device has a measurement unit for measuring a duration of an active state of the operation switch, a determination unit for determining whether the duration exceeds a predetermined time, and a control unit for executing a power supply transition control of the vehicle based on the determination that the duration time of the active state of the operation switch exceeds the predetermined time made by the determination unit and an authentication result of the authentication unit.

An automobile power supply control device for performing a control of switching a plurality of power supply circuits of a vehicle based on an operation of a push button type operation switch has a plurality of switching units for connecting the power supply circuits and a vehicle battery, and a control unit for performing a control of driving the switching units in a predetermined order according to number of operations of the operation switch. The control unit has a first detecting portion for detecting the operation of the operation switch, an output portion for outputting a drive command for driving the switching unit of next order when the first detecting portion detects the operation of the operation switch, and a second detecting portion for detecting the number of operations of the operation switch from a time point the drive command is output until a contact of the driven switching unit is switched. The switching units are driven in order by the number of operations detected by the second detecting portion, which driving is terminated when a last switching unit of the predetermined order is driven, or terminated when a first switching unit of the predetermined order is driven.

摘要:
To provide a catalytic converter that reduces non-uniformity of temperature of a catalyst support and that can approach a uniform temperature distribution, and a structural body for supporting a catalyst that structures this catalytic converter. At a catalyst support, gradually decreasing width portions, at which a width thereof gradually decreases toward electrode centers, are formed at regions where electrodes, are contactingly disposed, as seen in a cross-section orthogonal to a direction in which exhaust flows. The width is shorter than a length of a center line at a given position. Heat generation and heat dissipation of the catalyst support are balanced overall.

There is disclosed a honeycomb structure which solves a problem of antinomy that it is difficult to satisfy both of a high temperature rise performance and a high thermal capacity at the same time and which is disposed at a previous stage of a filter for trapping particulate matters (PM) discharged from a diesel engine so that regeneration of the PM trapped by the filter can smoothly be completed and an exhaust gas can efficiently be purified. In a honeycomb structure in which a plurality of cells arranged in parallel with one another to communicate between two end surfaces of the honeycomb structure are formed by a plurality of partition walls, the plurality of partition walls are made of a ceramic, and constituted of partition walls having two or more types of thicknesses.

In a honeycomb filter in which a plurality of cells are formed by porous partition walls, and a predetermined cell whose one end portion is plugged, and a remaining cell whose other end portion is plugged are alternately arranged in such a manner as to form checked patterns in the opposite end portions. In a section of the filter, a sectional area of the predetermined cell is different from that of the remaining cell, a value of a ratio of a channel hydraulic diameter of the cell having a large sectional area to that of the cell having a small sectional area is 1.2 or more, at least a sectional shape of the cell having the large sectional area is a quadrangular shape whose portion corresponding to at least one corner portion is circular, and a value of a ratio of minimum thickness of a portion (intersection portion) in which the partition walls cross one another to a thickness of each partition wall 2 is 0.7 or more and less than 1.3. The honeycomb filter is capable of inhibiting a fluid inflow-side end face (opening of an inflow-side cell) from being closed by particulates and the like, and maintaining high strength.
