摘要:
A multilayer ceramic capacitor 1 having dielectric layers 2 having barium titanate or barium calcium titanate as a main ingredient. When the dielectric layers are barium titanate, the ratio of the grains having a thickness of the crystal grain boundaries 22 present between adjoining dielectric grains 20 is 30% to 95% of the plurality of dielectric grains 20 forming the dielectric layers 2. When the dielectric layers 2 are barium calcium titanate, the ratio of the grains having a thickness of the crystal grain boundaries 22 present between adjoining dielectric grains 20 is 20% to 70% of the plurality of dielectric grains 20 forming the dielectric layers 2.

An electronic authentication system includes a vehicle-side control unit that judges whether ID information of an electronic key is identical to vehicle-side ID information, an ignition switch unit that permits engine starting operation and handle unlocking operation on the basis of the identity of the ID information of the electronic key to the vehicle-side ID information, and an actuator that unlocks an opening and closing lid such as a accommodation box lid. These component members are attached and fixed to a leg shield (an inner leg shield) and modularized. These members are preassembled into the inner leg shield and modularized like this, whereby the assembling work into the vehicle becomes very easy and it is possible to make the assembling work efficient to a great extent.

A reproducing device provided with a resume function capable of storing a plurality of stop positions through a simple operation is provided. In a reproducing device 1 for reproducing a recording medium 2, if an operation of stop position storage means 12c of a microcontroller 12 is instructed by operation means 14 during reproduction of video, the stop position storage means 12c erases the oldest stop position from among stop positions stored in a stop position storage area 13a which is capable of storing a plurality of stop positions of a memory 13 which stores stop position information on positions at which the video is stopped and stores the stop position in a free space area of the stop position storage area 13a resulting from such an erasure, and can thereby store a plurality of stop positions through a simple operation.
