Title: Semiconductor laminated structure and its production and semiconductor device therewith
Inventor: UCHIDA YOKO
IPC: H01L21/203
Filed: 1995-07-05
Abstract: PROBLEM TO BE SOLVED: To unnecessitate the cleaning treatment for substrate surface through a high-temperature treatment, suppress the diffusion of impurities and to permit an epitaxial growth of a GaAs layer by adopting an Si substrate whose surface is inactivated through hydrogen termination. SOLUTION: A p-type Si substrate 1 is dipped in a hydrofluoric acid solution and it is carried in a molecular beam crystal growth apparatus thereafter. A Ga layer 2 is formed on the substrate 1. An As is emitted thereto to change the surface layer of the layer 2 into a GaAs layer 3. Then a heavily doped p-type GaAs layer 4 is formed thereon. The temperature of the substrate is increased up to 300 deg.C or 600 deg.C, and a p-type GaAs layer 5 and a heavily doped n-type GaAs layer 6 are piled up thereon successively. Further, an n-type AlGaAs layer 7 is piled up thereon as a window layer, and a heavily doped n-type GaAs layer 8 is piled up thereon as an electrode joint. The layer 8 is etched while only an n-type electrode part is left as it is, so that an n-type electrode 9 and a p-type electrode 10 are formed.  The prepared photoelectric conversion element has an efficiency of 70-80% compared with that of a general purpose GaAs one.

Filed: 1990-06-27
Abstract: PURPOSE:To facilitate the maintenance of a cleaning roller by rotating a supporting member which attachably/detachably supports the cleaning roller centering around the shaft center of a press-contact roller to the separating position of the cleaning roller. CONSTITUTION:In the case of exchanging the cleaning roller 4, a fixing device 1 is pulled out from the mount port of an image forming device main body and the upper part 10 of the device 1 is opened. Continuously, by pulling up the guide plate 24 of the press-contact roller unit 5', the entire unit 5' rotates in a direction shown by an arrow R centering around the shaft 7 of the press- contact roller 3. With the rotation thereof, the roller 4 which exists at a cleaning position shown by a broken line hitherto rotates and moves to the separating position shown by an alternate long and two short dashes line. Then, pressing force by a leaf spring 9 toward the shaft 7 for the roller 4 is gradually decreased and the pressed state of the roller 4 is released when the roller 4 is separated from the spring 9. Therefore, the roller 4 is easily taken out from the mount groove 6 of a cleaning roller supporting plate 5 at the separating position.

Abstract: PURPOSE:To effectively destaticize the electric charge which is accumulated on the surface of a sleeve and to ensure the stabilized development for a long period of time, by giving destaticization to the surface of the sleeve after eliminating the toner of the developer out of the sleeve and before the attachment of the new toner. CONSTITUTION:A conductive blade 10 that scrapes off the toner after the development is set opposite to a conductive sleeve 7 which has a magnet 11 and is covered with an insulated material 11 on the surface. This blade 10 is grounded to eliminate the electric charge on the surface of the material 11. It is sometimes impossible to perfectly eliminate the electric charge on the surface of the material 11 by means of the blade 10 only. In this connection, the 2nd destaticizing means comprising a destaticizing brush 13 is added when necessary. The only conditions for destaticization is that the area to which no toner is attached is destaticized. Thus other constitutions than that mentioned above will be available for the destaticization. A corona discharger is also available for the destaticizing means.

Filed: 1987-07-10
Abstract: PURPOSE:To contrive the improvement of the echo suppressing effect without increasing the tap number of an adaptive FIR digital filter by suppressing echo tail by the IIR digital filter whose coefficient is set in advance. CONSTITUTION:Each tap coefficient in a coefficient register 14 of the IIR digital filter 16 is preset so as to have a characteristic approcimating the average characteristic of an echo generated by various subscriber lines.

Moreover, the adaptive type FIR digital filter 7 is operated to cancel the difference between the echo included in the reception signal and the pseudo echo 17. Thus, the echo suppressing performance is improved without increasing the tap number of the adaptive FIR digital filter.

Abstract: PURPOSE:To equalize base-emitter voltages of input and output side transistors and to reduce a distortion between input and output voltages by supplying a current having the same magnitude as that of a current flowing to the input side transistor, to the output side transistor by a current mirror circuit. CONSTITUTION:An input voltage, an output voltage, a base-emitter voltage of an input side transistor 3, a base-emitter voltage of an output side transistor 4, a current flowing to the input side transistor 3, and a current flowing to the output side transistor 4 are denoted as VIN, VOUT, VBEIN, VBEOUT, IIN and IOUT, respectively. In this case, when an input side resistance 5 is denoted as RIN, IIN=(VIN-VBEIN)/RIN is derived, and depends on the input side resistance 5. When a current amplification factor hFE is the infinite, since each base-emitter voltage of the input side and the output side transistors 3, 4 in a current mirror circuit is equal, IOUT becomes equal to IIN. Accordingly, VBEIN and VBEOUT also become equal, and VOUT becomes equal to VIN. In such a way, a distortion between input and output voltages can be reduced.
