Title: On-vehicle navigation apparatus
Inventor: SAEKI MASAHIRO
IPC: G08G1/0969
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To keep on displaying a map or guiding route even by the discharge of a map-information storage means by providing a second map-readout control means by which map information on a position near a present position is read out from the storage means so as to be stored in a storage means. SOLUTION: In an information readout means 2, a map storage means 1 can be separated from a system by a user's map-storage-means discharge command which is input from an input means 3. At this time, map data cannot be read out from a readout means 2. Then, the creation of display data in a display control means 8 by means of map data which is read out by a first map-readout control means 4 is changed over to the creation of display data by the control means 8 by means of map data which is read out into a second map-readout means 5 by a system control means 10. In this manner, since wide- area map data is read out into a storage means 7 before the discharge of the storage means 1 by the second map-readout control means 5, a present-position map can be displayed for many hours even after the discharge of the storage means 1.

Filed: 1985-11-20
Abstract: PURPOSE:To accurately form an arbitrary doping profile by providing an electron beam emitting mechanism in a furnace for generating gas molecule flow including an element to become a dopant, and controlling accelerating voltage and current of electrons. CONSTITUTION:A valve 14 is opened before growing or during growing of GaAs on a substrate 24 heated by a heating filament 27 to introduce dopant gas to emit an electron flow. The gas is partly or partially decomposed by the emission of the electron beam to become radical to arrive at the substrate 24.
