Abstract: Disclosed is a method of locking the functions of a mobile telephone system. At least two lock codes are stored in a memory together with the functions to be kept locked or actuated when the locked state of the mobile system is released. The locked state of the automobile is not released unless a registered lock code is input. When the locked state is released by inputting one of the registered lock codes, some functions remain in the locked state in accordance with the input lock code, while other functions are actuated. Thus it is possible to limit the use of the mobile telephone system depending upon who drives the car.

Abstract: An improved collimating lens for use in optical memories is disclosed which comprises a first surface for receiving the incident beam which is concave, and a second surface for emitting the outgoing beam which is convex and non-spherical, characterized in that the said lens satisifies some particular conditions. If the collimating lens of the present invention is used, the beam passing through the periphery of the lens can be concentrated, and therefore, the actual number of openings of the objective lens is increased, and at the same time, the coupling efficiency can be improved. Accordingly it is possible to form very tiny spot on the disc, and the transmission rate can also be improved. Further, the appearance of the lens can be favorably shaped when manufacturing the lens, because the lens of the present invention is strong against the difference of the axes.
