IPC: H01L21/8222
Filed: 1992-07-10
Abstract: PURPOSE:To monolithically form a plurality of semiconductor elements different in withstand characteristics on the same substrate. CONSTITUTION:A buried layer 3 is formed between a high withstand voltage element 16 for output and a substrate 1. A buried layer 4 is formed between a low withstand voltage element 15 for control and the substrate 1. The buried layers are formed by using materials different in the diffusion coefficient. The buried layer 4 formed by using material whose diffusion coefficient is thick, and the buried layer 3 is thin. Thereby the interval between the buried 4 and the low withstand voltage lement 15 for control becomes larger than the other, and the collector resistance can be reduced. Since the buried 3 is formed so as to be thinner than the buried layer 4, the distance between the high withstand voltage element 16 for output and the buried layer 3 can be made large, and high withstand voltage can be ensured.

Title: Gain variable circuit
Inventor: TAKAHASHI YUTAKA
IPC: H03G3/12
Filed: 1987-08-20
Abstract: PURPOSE:To obtain a gain variable circuit with high accuracy and low distortion without being affected by the turn on resistance of an analog switch, by grounding a gain variable resistor by utilizing the virtual ground of an operational amplifier. CONSTITUTION:When only the analog switch S1 is turned on, a changeover switch Se1 is connected to a ground side, and change-over switches Se2-Sen to a positive power source V<+> side. Thereby, only the operational amplifier A1 is set at a total feedback state. Therefore, at this time, the inversion input terminal (-) of the amplifier A1 becomes the virtual ground. In such a case, the same result is obtained even when a certain amount of impedance is attached on the switch S1. At this time, the gain G of an amplifier circuit consisting of the operational amplifier Af is decided by the resistance values rf and r1 of resistors Rf and R1. Thenceforth, it is possible to realize (2<n>-1) kinds of gains by the combination of the analog switches S1-Sn. Thus, it is possible to attain a purpose.

Abstract: PURPOSE:To transfer film without contact with a painted part by holding a part between the painted part and the painted part of the film with a hook and the outer surface of an outer frame by the driving of a solenoid, and driving a motor between two limit switches. CONSTITUTION:Under the initial operating condition, an outer frame 101 is rotated under the state wherein a hook 104 is separated from the outer surface of the outer frame with a spring 105 by a control device. A film 1 is positioned between the hook 104 and the outer surface of the outer frame 101. Under this state, the film is turned to a position where the hook 104 comes to contact with a limit switch 107. The film 1 having the painted part of a specimen is transferred by 1/4 of the outer surface of the outer frame 101. Then, current conduction through a solenoid 102 is stopped, and the hook 104 is separated from the outer frame 101. The frame is rotated into the reverse direction until the hook 104 comes to contact with a limit switch 108. Then, the hook 104 is rotated under the state wherein a part between the painted parts of the film 1 is held. Thus the film 1 is transferred by a specified amount at a specified speed.

Title: Hetero junction field effect transistor and manufacture thereof
Inventor: MATSUMOTO FUMIO
IPC: H01L29/778
Filed: 1989-08-09
Abstract: PURPOSE:To obtain a stable ohmic electrode of low resistance and excellent Schottky characteristics by arranging a specified electron supply layer of high impurity concentration in the position closer to a semi-insulating substrate than a specified channel layer and arranging a non-doped or low-impurity-concentration barrier layer in the position near a surface, and electrodes on said barrier layer. CONSTITUTION:On an electron supply layer 3 formed on a semi-insulating substrate 1, a channel layer 5 and a barrier layer 6 are laminated in order in this constitution. Compared with the forbidden band width of the channel layer 5, that of the electron supply layer and of the barrier layer are made wider. The electron supply layer 3 is composed of AlxGa1-xAs or Inx'Al1-x'As, and the channel layer 5 is composed of InyGa1-yAs, further the barrier layer 6 is composed of GaAs. As the electron supply layer 5 composed of AlGaAs is located in the position closer to the substrate 1 than the channel layer composed of InGaAs, even if an Si concentration in the electron supply layer is made higher, influence of the gate electrode upon Schottky characteristics is little. Also, as a non-doped or low-Si-concentration GaAs layer is located closer to a surface than the channel layer, it can realize the stability of an ohmic electrode, elimination of a hetero junction barrier resistance, reduction of resistors connected to sources in series, and enhancement of a gate withstanding voltage.

Title: Output buffer amplifier circuit
Inventor: SATOU NORITOSHI
IPC: H03G1/00
Filed: 1992-08-04
Abstract: PURPOSE:To reduce the occupied area by the circuit by connecting a transistor(TR) switch group deciding an amplification factor at an optional value to a noninverting input terminal of the output buffer amplifier having a high impedance. CONSTITUTION:A TR switch group 4 connects between a feedback resistor 3 and a noninverting input terminal of the output buffer amplifier 5 and since the impedance of the noninverting input terminal of the output buffer amplifier 5 is high, a current flowing to a closed switch is regarded as nearly 0. That is, the ON resistance of a TR switch is neglected. Thus, the fluctuation in the ON-resistance due to a fluctuation in a terminal voltage of the TR switch does not give effect on the amplification factor. Since the resistance of the feedback resistor 3 has no correlation with the size of the TR of the TR switch group 4 in this way, the size of the TRs is designed optimum independently thereby making the size of the circuit small.
