IPC: G01N27/12
Filed: 1994-01-25
Abstract: PURPOSE:To obtain a highly reliable semiconductor gas sensor by providing a first gas-sensitive layer of a metal oxide semiconductor supporting a noble metal catalyst, and a second gas-sensitive layer of a metal oxide semiconductor on the same one substrate. CONSTITUTION:Since first and second gas-sensitive layers 11, 12 are provided on the same one substrate 13, they are subjected to the interfering gas, the steam and the fluctuation of power supply voltage. The gas layer 11 is composed of a metal oxide semiconductor supporting a noble metal catalyst and detects combustible gas, interfering gas and steam entirely. The gas layer 12 is composed of a metal oxide semiconductor and detects the interfering gas and steam at the same level as the gas layer 11 but the sensitivity to the combustible gas is extraordinarily lower than the gas layer 11. The sensitivity to combustible gas of the gas layer 11 has been improve significantly by using a noble metal catalyst. Fluctuation in temperature due to fluctuation of power supply voltage gives the same effect on the first and second gas-sensitive layers.

Title: Diffusion mask and manufacture of p-n junction element using the same
Inventor: OGIWARA MITSUHIKO
IPC: H01L21/225
Filed: 1995-01-19
Abstract: PURPOSE: To obtain a diffusion mask having corrosion resistance against an HF-series etchant. CONSTITUTION: An AlN diffusion mask 18, a diffusion source 20 and an AlN anneal cap 22 are formed sequentially on a main surface 10a on the front side of an n-GaAs substrate 10. The diffusion source 20 is a film of a mixture of ZnO and SiO2 . Moreover, an AlN anneal cap 24 is formed on a main surface 10b on the rear side of the substrate. Thereafter a Zn diffused region 26 is formed by solid-phase diffusion. Then, the anneal caps 22 and 24 are removed by a hot phosphoric acid and further the diffusion source 20 is removed by HF or buffered HF. Since the diffusion mask 18 has corrosion resistance against the HF or the buffered HF, a diffusion window 12 of the diffusion mask 18 is not widened or no hole is formed in the diffusion mask 18 when the diffusion source 20 is etched.  Therefore the diffusion source 20 can be removed by etching without impairing the layer insulating function of the diffusion mask 18.

Filed: 1991-01-24
Abstract: PURPOSE:To contrive the extension of a time up to the cleaning of a light emission element and a light receiving element by changing over a light emission quantity and a slice level in accordance with a quantity of soiling or the light emission element and the light receiving element to discriminate a degree of soiling and setting a proper light quantity. CONSTITUTION:In a discrimination processing part 7 output voltage VOUT generated at both ends of load resistance is compared 4 with a slice level VSL to discriminate the pressure of a medium 3, and a light emission quantity setting part 5 and a reference voltage setting part 6 are controlled to change over between the light quantity and the slice level VSL in accordance with a quantity of soiling adhered to a light emission element 1 and a light receiving element 2. If VOUT <= the initial value VSL of the level shown, a light quantity is enlarged since soiling is accumulated. In addition, because the discrimination is performed on whether soiling is within the range of allowable limits if VOUT is shown, VSL is changed over to the value VSL2 (<VSL1) at the time of practical use (medium detection). If VOUT<=VSL is shown, the soiling is beyond the allowable limits and the cleaning of the elements 1, 2 is performed. Thereafter VOUT is compared with VSL2 and it is discriminated that if VOUT >VSL2 is shown, there is no medium 3 and there is the medium 3 if VOUT>VSL2 is shown.

Filed: 1993-01-19
Abstract: PURPOSE:To properly collect information regardless of the presence of a station connected through a repeater by holding the address which is finally received by each input port and is used by the high-order protocol of the transmission source station in a frame. CONSTITUTION:Every time the frame transmitted by a station 104 is arrived, a line concentrator 102 internally holds the IP address of the transmission source station written in the IP header of the frame. Since a router 103 relays the frame without rewriting the IP address of the transmission source in the frame at the time of relaying the frame from the station 104 to the line concentrator 102, the line concentrator 102 holds the IP address of the station 104. When the frame arrives at a designated input port, the line concentrator 102 immediately transmits the IP address of the transmission source station of the received finally with this input port to a management station 101. Consequently, the management station 101 collects the information of the station 104.
