摘要:
An optical recording medium has a recording layer formed on a substrate possessing a light transmissive property, through which a light for recording and reproducing is irradiated to the recording layer. The substrate contains a light absorbent so as to allow only the light for recording and reproducing to pass through the substrate. The recording medium exhibits a good light-resistance.

A navigating apparatus which outputs information for guidance to a destination comprises an input device (1) for inputting a destination and a present position, a memory (4) in which guidance information is stored, an arithmetic unit (2) for determining optimum guidance information from the information input from the input device (1) and a display (3) for indicating the guidance information, the memory (4) having data of a plurality of parking lots at least in a destination and the arithmetic unit (2) serving to select the plurality of parking lots and guide the driver along the courses thereto in the destination. This apparatus enables the driver to go to a nearby parking lot by exploration of a course to the next parking lot at the shortest distance and guidance thereto even if a certain parking lot is full of cars in a destination.

When a semiconductor device having a multi-layered contact is fabaricated, the gate electrode is covered with a thick insulator film. A polycrystalline silicon film is formed in a state in which at least the gate electrode in the contact forming area is covered with a first oxidization-proof insulator film. An inter-layer insulator film is then formed in a state in which at least part of the polycrystalline silicon film is covered with a second oxidization-proof insulator film. A first contact hole is formed using the polycrystalline silicon film as an etching stopper, and the polycrystalline silicon film is then oxidized. Furthermore, a second contact hole is formed in the inter-layer insulator film on the upper surface of the second oxidization-proof insulator film using as the etching stopper the polycrystalline silicon film underlying the second oxidization-proof insulator film. Since the polycrystalline silicon film is formed under the inter-layer insulator film in the second contact forming area so as to cover the gate electrode, it acts as a stopper when the second contact is formed to thereby prevent a short circuit with the gate electrode even if there is no distance between the gate electrode and the second contact.

Disclosed is a system for preparing a route end node series which is equipped with a route search means 7 for preparing a node series, an intersection series or a combination of both as the data series for navigation, and a route end node series preparing means 3 for preparing the node series from the starting point and the destination to the respective nearest particular points. The route end node series preparing means 3 prepares node series by successively performing node search until the node nearest to the point indicated by the positional information on the starting point or the destination is attained. This construction makes it possible to perform course guidance through navigation based upon the node series between the starting point or the destination and the nearest intersection thereto even if the starting point or the destination is set at a point between intersections when particular points are set as intersections.

A method of making a magneto-optical recording medium comprises the step of forming a magneto-optical recording layer on a substrate by simultaneously carrying out direct current sputtering and radio-frequency sputtering. Alternatively, a magneto-optical recording layer composed of thin rare earth metal layers and thin transition metal layers overlaid alternately on a substrate is formed by carrying out radio-frequency sputtering by use of a target formed of a rare earth metal material and direct current sputtering by use of a target formed of a transition metal material.

A method of making a magneto-optical recording medium comprises the steps of moving a rotating substrate along a first dielectric target, at least one rare earth metal target, and a second dielectric target which are disposed in this order from an upstream side toward the downstream side in an in-line sputtering apparatus, and carrying out simultaneous sputtering on the substrate in the course of the movement of the substrate by use of the first dielectric target and the rare earth metal target. Thereafter, sputtering is carried out on the substrate by use of the rare earth metal target. Then, simultaneous sputtering is carried out on the substrate by use of the rare earth metal target and the second dielectric target.
