Title: Semiconductor photodetector
Inventor: TERAKADO TOMOJI
IPC: G02B5/08
Filed: 1989-01-27
Abstract: PURPOSE:To eliminate the influence of a stray light and to perform an ultrahigh speed of an optical response to be determined according to the running time of optical carrier generated in a depletion layer by surrounding a photodetecting face formed on the part of a semiconductor layer with a high reflection mirror made of a dielectric multilayer film. CONSTITUTION:In a PIN photodiode which has first, second buffer layers 11, 12, a light absorption layer 13, and a transparent window layer 14 for an incident light, selectively formed on a semi-insulating semiconductor substrate 10 made of a Fe-doped InP, a high reflection mirror 16 made of a dielectric multilayer film is formed around a p-type inverting region 15 to become a photodetecting face. Thus, the periphery of the photodetecting face is surrounded by the high reflection mirror 16 made of the dielectric multilayer film to reflect a stray light on the mirror 16, and the light is not absorbed except the photodetecting face. Since the light is not absorbed out of a depletion layer, the diffusing current of optical carrier is eliminated. Since the mirror 16 is made of dielectric, an excess capacity is not generated to a photodetector layer. Accordingly, a photodetector having an ultrahigh speed of an optical response determined according to the running time of optical carrier generated in the depletion layer can be formed.

IPC: B23H1/02
Filed: 1989-01-30
Abstract: PURPOSE:To attain rapid position control by subtracting a following error from a difference between a reference objective value and a detected distance. CONSTITUTION:A working condition setting means 11 commands a reference distance lb between an electrode 33 and an object 34 to be worked. On the other hand, an average voltage detecting circuit 18 detects an average voltage Vn between the electrode 33 and the object 34 to be worked and sends the detected result to an A/D converter 17. The converter 17 converts the voltage Vn into a digital value and sends the digital value to an inter-pole voltage detecting means 13. The means 13 calculates an inter-pole distance lm from the average voltage value and sends the calculated result to a computing element 14. The means 14 subtracts the distance lm from the distance lb and calculates its deviation and a moving variable calculating means 15 sends a moving variable Cn to a servo moving command calculating means 16. The means 16 outputs an inter-pole moving variable Pn obtained by subtracting a following error En from the moving variable Cn to a servo position control circuit 21. Thereby, gain can be increased and the movement of the electrode 33 can rapidly be controlled. The circuit 21 sends the command Pn to a speed current control circuit 22 to drive a servo motor 31.

Filed: 1980-02-20
Abstract: PURPOSE: To prevent the lowering of both the frequency characteristics and S/N that are caused by the impedance of a connection cord, by providing a by-pass circuit.  
     CONSTITUTION: A by-pass circuit Z0 consisting of a capacitor C and a resistance R is connected between the feedback input terminal 28 of the amplifier 12 and the earth. The value is set at C=l/r 2  and R=r [(l) and (r): inductance and resistance of connection cord l 2 ] for the capacitor C and the resistance R. The power supply switch is turned on, and the muting switch s is closed. Thus the acoustic signal supplied to the input terminal IN is amplified through the amplifying circuit 14 and then supplied to the speaker 22 via the muting switch S and the external output terminal 20A. In this case, the input voltage of the feedback circuit 30 does not increase although the frequency of the acoustic signal increases since the inductance component of the cord l 2  is negated by the circuit Z0. As a result, an extraordinary increase of gain or lowering of S/N can be avoided.
