There is provided a navigation device including a position information acquisition section which acquires a current position, a final destination setting section which sets a final destination, a stop-off genre setting section which sets a genre of a facility to be stopped at, a stop-off point selection section which selects a stop-off point based on a route to the final destination, and a route guidance section which performs notification of a route to the stop-off point at a branch point between the route to the final destination and the route to the stop-off point, shows a route to the stop-off point when entering the route to the stop-off point from the branch point, and switches a guidance destination to the final destination when arriving at the stop-off point.
摘要:
A rocker arm that is rockably attached to a cylinder head actuates a valve by a guide groove that is formed at an end thereof engaging with an upper end of a valve stem, and a roller that is mounted in a roller housing portion of the arm main unit contacting against a cam and rocking. The guide groove is formed by press working ends of the arm main unit in the thickness direction of the plate material to form a pair of walls, and thereafter applying sandwiching pressure in the lateral direction to the walls to increase the height thereof.

A production process control system includes a plurality of terminal devices and a central device connected to the terminal device. Each of the terminal devices has at least an element for counting the amount of work done and generating a corresponding output, an element for entering a worker identifying code, an element for transmitting the counted output and the entered worker identifying code to the central device and an element for providing an output cancel signal by which, in conjunction with the counted output, a current output value is updated. The central device at least has an element for performing communications with each terminal device and an element for storing the output and the worker identifying code transmitted from the terminal device as associated with each other. In one aspect of the invention, there is provided in a terminal device a bar code reader for reading a bar code recorded on a medium, a bar code reader withdrawal detecting switch, and an alarm that acts when no input is received from the bar code medium over a predetermined lapse of time after detection of a bar code reader withdrawal.
