Abstract: PURPOSE:To execute a satisfactory code series reproduction even when a linear distortion due to delay components is generated by generating fundamental waves corresponding to the delay components contained in a receiving digital signal, respectively, and obtaining a correlation between the fundamental wave and the receiving digital signal. CONSTITUTION:When a modulating wave is supplied to an input terminal 1, a correlation device 2 for extracting components obtains the correlation between a receiving signal and a code series, extracts a specific code series, and outputs a complex delay profile. A fundamental waveform generator 3 generates the fundamental waveform to the delay time of the delay profile, and it is supplied to a fundamental waveform correlation device 4. Further, the modulating wave is supplied to the correlation device 4, the correlation between each fundamental wave and a code series part is obtained, and it is stored into a correlation memory 5. A distance arithmetic device 7 obtains a signal space distance based on the contents of the memory 5, a degenerating pass memory 6 and a condition transition memory 9. A condition deciding device 8 determines a condition, the condition transition memory 9 considers that the modulating wave with the smallest signal space distance is received, and the corresponding code series is outputted to a decoder 10.

Title: Optical filter and its manufacture
Inventor: TAKAHASHI YASUNORI
IPC: G02F1/1335
Filed: 1984-02-15
Abstract: PURPOSE:To obtain an optical fiber capable of the display surface of a CRT, etc., becoming a reflection mirror by cutting off external oblique light to the display surface by absorption. CONSTITUTION:The optical fiber A has a horizontal pattern to the display surface of the CRT4, etc. Light from an interior ceiling lamp and the natural sunshine are oblique rays (r), which pass through a transparent substrate 5 and a primer layer 8, but at least visible rays are absorbed by projection streaks 7 to cut off externa light made incident on the display screen 4a. Therefore, the contrast between bright points and their periphery on the display screen 4a is not canceled with the externa light to obtain a sharp image. When a polarizing plate is used as the substrate 5, a circular polarizing plate with extremely small reciprocal transmissivity of externa light is recommended. Then opposite surfaces of the projection streaks 7 are roughened finely almost at right angles to the surface of the transparent substrate 5. Furthermore, a photosetting resin layer is formed on one surface of the transparent substrate 5 and etched away in an etchant except at the photosetting part to fix plural projection bodies of the resin on the surface of the transparent substrate.

Title: Decoder circuit
Inventor: KUWABARA SUMIO
IPC: G11C11/34
Filed: 1985-02-13
Abstract: PURPOSE:To obtain a decoder circuit which consists of a small number of transistors TRs of the 1st conduction type and the TR of the 2nd conduction type whose gate connected between the 1st node and the 2nd power source is connected to one of gates of plural TRs of the 1st conduction type in common. CONSTITUTION:When input signals phi1-phi3 are '0', a P channel MOS TR Q1 is on and N channel MOS TRs Q2-Q4 are off, so a node N1 is precharged to a power source potential Vcc and an output node N4 is grounded. When the input signals phi1-phi3 are all '1', the P channel MOS TR Q1 turns on and all the N channel MOS TRs Q2-Q4 turn on. Therefore, the node N1 is grounded through the N channel MOS TRs Q2-Q4 and the output node N4 is held at the potential Vcc. Consequently, the decoder circuit operates without any precharge signal and by a small number of TRs.

Filed: 1978-03-04
Abstract: PURPOSE: To provide welding wire for cast iron, with small coefficient of thermal expansion, excellent in crack resistance of deposited metal and in mechanical properties, and made of alloy with specific composition and hardness.  
     CONSTITUTION: The wire is made of an Ni-Fe alloy consisting of, by wt., 50W60% Ni, 0.4W1.0% Mn, 0.15W0.4% Si, 0.5W8.0% Mo, the remainder being Fe, and has a hardness in a range of 100W300 Hv. Si of 0.15% or more is required for increasing the fluidity of the molten metal, however 0.4% or moe of Si makes the welded metal britle. Mo of 0.5% or less increased longitudinal crack effect in the bead of fillet weld, and 8.0% of more of Mo deteriorates the toughness of the deposited metal. Hardness of 100Hv or less causes buckling distortion, and 300 Hv or more makes the feed of the wire difficult because of excessive hardness.
