摘要： An ultrasonic apparatus measures the concentration and flow rate of a sample gas by calculating a possible propagation time range on the basis of the gas temperature, determining whether or not the phases at which two first trigger signals, respectively generated on the basis of forward and backward waveforms of the ultrasonic waves, coincide with each other, processing the zero-cross signals so that the phases coincide with each other, obtaining reference zero-cross time instant by calculating mean value of the forward and backward zero-cross time instants, obtaining an ultrasonic reception point by subtracting an integral multiple of the cycle of the ultrasonic waves so that the results of the subtraction falls into a possible propagation time range and estimating the ultrasonic propagation time on the basis of the ultrasonic reception point.

摘要： 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.

摘要： 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. Further, there is also shown a gas supply apparatus that comprises ultrasonic type gas concentration and flow rate measuring means that comprises, in turn, two ultrasonic transducers that is disposed in an opposed manner in the conduit through which product gas flows so that a concentration value measured when the product gas output is stopped is determined to be a product gas concentration.
