Abstract: A three dimensional manufactured product is manufactured A speed of filing an uncured light curing resin in a space for a next layer is enhanced, to improve a manufacturing speed. One surface of a container housing a light curing resin is configured by a gas-permeable sheet that faces the light curing resin, and transmits irradiation light of a light irradiating apparatus, and a light transmitting plate disposed at an outer side of the container from the gas permeable member. A pressurizing chamber controllable in pressure by a pressure controlling apparatus is defined between the gas-permeable sheet and the light transmitting plate. At moving a manufacturing stage, an inside of the pressurizing chamber is de-pressurized to cause the gas-permeable sheet to perform concave surface deformation, and at a time of performing light irradiation, gas in the pressurizing chamber is caused to permeate into the light curing resin by pressurizing.

Abstract: An onboard navigation system detects a condition that a recognized present position of the vehicle belongs to a map of a peripheral part of a region covered by map data groups recorded on a recording disc. If a changer type driver is used as a player for reproducing map data, the recording disc being played is changed to a new disc in response to the detection of the above described condition. If a single driver is used, identification information of a corresponding disc is displayed. With these features, the disc being played is quickly changed to a required new disc.

Abstract: A plurality of preset palette data are stored in a ROM. User palette data are input through an RS232C interface and stored in a nonvolatile RAM. Based on an instruction from a user and other information such as a signal indicating the status of an illumination switch, a MPU selects one of the palette data and sets the selected palette data in a look-up table. Image data representing a map, present position, etc. is converted into color data by the look-up table, and then to an analog video signal for a color CRT. A display can be made using the palette data prepared by the user.

Abstract: There is disclosed a navigation system adapted to support driving of a moving body such as an automotive vehicle. This navigation system determines a present position of a moving body in which the navigation system is mounted to display map information corresponding to the position of the moving body and the determined present position, and to store, as locus data, information of a route through which the moving body is advanced to display a movement route in map information. Storing of locus data is carried out by detecting a traveling azimuth to judge a change in the traveling azimuth to thereby compress locus data only to data in a predetermined range before and after the position where the azimuth is changed. Further, coordinate values in a map at the azimuth changed position and traveling azimuth data before and after the azimuth changed position are stored as locus data.

Abstract: An on-board navigation apparatus which uses a driver having a changer function to selectively reproduce any of music- and map-containing storage media. When it becomes necessary to read map data during reproduction of a music-containing medium, the current medium is replaced with the applicable map-containing medium upon arrival of an intra-music interval. This allows one driver driving both music and map data media to read map data without interrupting the piece of music being reproduced.

Abstract: An onboard navigation system for displaying a map in a scrolling manner while a mark showing the position of the vehicle is fixed. The system is adapted so that the fixed display position of the mark indicating the vehicle's position can be set at an arbitrary selected position, satisfying a user's demand for viewing a map of an area further ahead of the vehicle in the direction of the vehicle's movement.

Abstract: An on-board navigation apparatus having a GPS receiver detects a difference between the current and the previous values of the estimated current position in terms of the longitude and latitude information gained from GPS data. The difference is added to the coordinates of the previously established position, the result being taken for the coordinates of the estimated current position. This makes it possible to estimate the current position coordinates accurately even if the accuracy of GPS data is not high enough. When the GPS receiver is in a two-dimensional measuring state, the coordinates of the estimated current position are obtained from a manually or automatically designated elevation value and from the GPS data. This allows the current position coordinates to be estimated with accuracy even if the accuracy of GPS data has dropped due to the two-dimensional measuring instead of a three-dimensional measuring.
