Abstract: The head up display system (1) comprises a housing (5) installed within a dashboard panel (3) of the vehicle and provided with an open end (5o), a light emitting display device (12) placed in an opposite end of the housing remote from the open end to emit a display light, an optical unit (13; 23; 33; 43; 53; 63; 73) interposed between the light emitting display device and the open end of the housing. An outer element of the optical unit which may consist of a prism (15; 25; 35; 75) or a beam splitter (45) is configured to reflect an incident external light entering from the windshield (2) at least partly at an angle to the display light emitted from the outer element of the optical unit. Thereby, the external light reflected by the outer element of the optical unit may be directed into the housing or otherwise directed away from the vehicle operator's field of view, and the vehicle operator is allowed to obtain information simply by looking ahead of the vehicle without being annoyed by the external light.

Abstract: There is provided a vehicle having a simple and inexpensive structure that assists the driving sense. A front window shield 1 of a vehicle 100 is provided with a pair of marks 2 and 3 substantially horizontally aligned. The marks 2 and 3 are formed at the same height at the left and right sides of the front window shield 1. A driver perceives a virtual line L by the marks 2 and 3 on the front window shield 1, and trackings the line of sight W1 are induced to move such as to gather between the bottom end line (herein, a line of an instrument panel 6) and a virtual line L.

Abstract: An oxygen concentration apparatus (300) according to the present invention has: pressure swing adsorption type oxygen concentration means (310); and a control means (350) that controls switching means (316) that switches between intake of pressurized air into an adsorption column (312) and exhaust from the adsorption column. The switching means is controlled based on pressure in oxygen concentrated gas in the conduit measured by pressure measuring means to adjust a cycle of adsorption and regeneration processes of the oxygen concentration means so that pressure at the upstream of flow rate adjusting means (340) can be controlled and, as a result, the need for a mechanical pressure regulating valve, that has been needed conventionally, can be eliminated.
