Abstract: A security system includes a portable terminal, a communication device communicating with the portable terminal, and a determination unit determining validity of the portable terminal. Phase data acquired from distance measuring radio wave is used to determine validity of communication between the portable terminal and the communication device. The received phase data of the distance measuring radio wave varies according to the distance from a transmission source. When the communication device and the portable terminal are fixed, and the communication device and the portable terminal have transmitted and received distance measuring radio waves having the same specific frequency, vehicle acquisition phase data and terminal acquisition phase data are the same. The determination unit determines, by using this two types of phase data, the validity of communication between the communication device and the portable terminal is determined.

Abstract: A method of properly aligning a sliding side door on a vehicle includes first preparing a prototype vehicle and determining how far out of alignment the door is to the body of the prototype vehicle. This amount of misalignment is then used to adjust the attachment position of an anchor plate to a sliding side door of the vehicle, so that the anchor plate is attached at a desired position to the production vehicle, which causes there to be no misalignment between the sliding side door and the body of the production vehicle. A jig is used to hold the anchor plate at the desired location while welding the anchor plate to the door. A roller assembly is then attached to the anchor plate and to a rail on a body of the vehicle.

Abstract: An in-vehicle system executes authentication of a mobile device multiple times from a parking state until an engine is started. The in-vehicle system operates in an alert mode when a vehicle is parked, and transmits an authentication signal including a strength change signal. When the in-vehicle system operates in an alert cancellation mode, the mobile device returns a response signal only when there is a change in the strength of the received authentication signal. When the in-vehicle system succeeds in authentication of the mobile device in an authentication process in the alert mode, the in-vehicle system shifts to the alert cancellation mode. When the in-vehicle system operates in the alert cancellation mode, the mobile device returns the response signal irrespective of whether there is the change in the strength of the received authentication signal.

Abstract: Four regions (a narrow NMOS region, a wide NMOS region, a wide PMOS region, and a narrow PMOS region) are defined on a semiconductor substrate. Then, after a gate insulating film and a polysilicon film are sequentially formed on the semiconductor substrate, n-type impurities are introduced into the polysilicon film in the wide NMOS region. Next, by patterning the polysilicon film, gate electrodes are formed in the four regions. Then, n-type impurities are introduced into the gate electrodes in the narrow NMOS region and the wide NMOS region. As a result, an impurity concentration of the gate electrode in the narrow NMOS region becomes lower than that of the gate electrode in the wide NMOS region.
