IPC: H01L29/866
Filed: 1989-09-18
Abstract: PURPOSE:To improve the surge breakdown strength of a low voltage Zener diode and to lower the leak current value corresponding to the breakdown voltage by forming a region of the same conductivity as the main body and high in impurity concentration on the semiconductor body side of a pn junction face, and forming a guard ring deeper than at least the sum of the depths of both regions, surrounding both of them. CONSTITUTION:On the whole face of the N-type epitaxial layer 2 at the surface of an N-type semiconductor an N<+>-type diffusion layer 3 higher in impurity concentration than this is formed in depth k. The oxide film 4 on that is etched selectively to form a contact hole 7a, and boron (p-type impurities) are implanted circularily in depth l deeper than the depth k of the diffusion layer 3 so as to form a guard ring 5. Next, boron(B) is implanted in shallower depth m than depth k and in fixed concentration into the part 3a surrounded by this so as to form a P-type diffusion layer 6 being the same conductivity type as the guard ring 5. After that, additional diffusion is applied so that Zener voltage Vz may be nearly the desired value, and an electrode 7 is filled in a contact hole 7a, and is brought into contact with the diffusion layer 6, thus a constant voltage Zener diode 10 is obtained.

Abstract: PURPOSE:To reduce the weight and size of the frequency measuring instrument by providing a variable delay line and adjusting the delay time in the frequency discriminating circuit in an IMF receiver electrically. CONSTITUTION:A control signal generating circuit 32 detects an input signal (a) to generate a control voltage (e) and latch signals (f) - (i).

The signals (n) and (p) are sent to a frequency calculating circuit 31 through an encoder 25. Then latch circuits 26 - 29 latch the phase difference information of the circuit 23 with the signals (f) - (i) and an encoder 30 converts it into frequency information, which is outputted. Consequently, this device functions as if there were equivalently plural discriminating circuits, and also reduced in weight and size.

Title: Optical fiber core
Inventor: SHIYUDO YOSHITO
IPC: G02B6/44
Filed: 1985-10-30
Abstract: PURPOSE:To obtain an optical fiber core having a high bending characteristic by forming the orientation distribution of a secondary coat in its radius direction so that the orientation is relatively low in an outer surface part separated from a strand and it is relatively high in the inside of the coat layer. CONSTITUTION:A fiber strand 2 is supplied from a fiber strand feeder 1 and coated with thermoplastic resin at a part fed from a cross head die 3. The thermoplastic resin 5 for secondary coat is sheared by shearing force during the passage of it through a straight part 4 of the die 3 and pulled down at a part fed from the die 3, so that the resin 5 is highly efficiently orientated by the shearing force and extending force and applied to the surface of the fiber strand. After completing the coating processing, the temperature of the secondary coat layer is dropped less than a crystal/liquid crystal transfer point by air cooling, and after fixing the orientation, the outer surface part of the core is heated by an electric heater 6 and then solidified by a cooling tank 7. Then, the solidified fiber is wound around a core winder 8 as a core. Since the orientation distribution of the secondary coat layer of the optical fiber is formed so that the orientation on the outer surface part is low and that of the inside of the coat layer is high, the bending characteristic is remarkably improved as compared to an ordinary secondary coat layer.
