Title: Production of pitch for carbonaceous material
Inventor: ITOI MASAAKI
IPC: D01F9/155
Filed: 1983-12-26
Abstract: PURPOSE:To obtain a pitch high in its mesophase content, suitable for carbon fiber in high productivity, by separating heavy oil pitch intomesophase component and isotropic one taking advantage of specific gravity difference between them followed by removing residual isotropic pitch from the mesophase one by specified means. CONSTITUTION:First, a heavy oil (pref. with high aromatic hydrocarbon content, such as a residual oil produced by catalytic decomposition of petroleum fraction) is heat-treated to separate the pitch formed into mesophase pitch and isotropic one taking advantage of specific gravity difference between them. Next, said mesophase pitch is brought into contact with a solvent of a solubility constant 8.5-12.5(cal/cc)<1/2> (e.g. toluene) to eliminate the isotropic pitch left in the mesophase one, thus obtaining the objective pitch. Said heavy oil as the raw material is preferably one with the ash contained having been eliminated beforehand along with the light oil fraction by vacuum distillation. EFFECT:Capable of giving carbon fiber with excellent spinnability and elastic modulus.

Filed: 1984-11-20
Abstract: PURPOSE:To shorten an operating time required after the output of a multiplier by forming a carry control circuit for obtaining a carry signal to be applied to an exponential part adder directly from the output of the multiplier. CONSTITUTION:The mantissa parts AM, BM of multiplication are added to the multiplier 2 and the outputted product DM is rounded to the prescribed number of digits by a rounding adder 4 on the basis of a rounding control signal RM obtained from a rounding control circuit 3. If carry is generated from the most significant bit as the result of rounding, the simply added result of the exponential parts AE, BE, by an exponential adder 7 should be compensated. To shorten the time required for the compensation, the product output before rounding is applied from the multiplier 2 directly to the carry control device 5, whether the round result requires the compensation of the exponential parts or not is decided and the decided result CM is applied to the adder 7 as the carry input to compensate the exponential parts of the product.

In other words, N4 can be set not identical to N3×N2/N1 but to a value close to it. Thus a composite hypocycloidal reduction gear mechanism A of a minimum difference in the number of tooth having a remarkably small reduction gear ratio is formed and rotation of an input shaft can be remarkably reduced and transmitted to an output shaft 5.

IPC: H04N7/01
Filed: 1991-09-25
Abstract: PURPOSE:To successively obtain a scanning reproduction picture of a dynamic picture with the same resolution as a still picture by preparing an auxiliary signal from an input signal with a main passing scanning signal from a successive scanning input signal completed for each frame. CONSTITUTION:An encoder 101 delays the successive scanning input signal by one field in delay circuits 1-1 and 1-2, converts the output signal of the circuit 1-1 into the passing scanning form in a successive passing exchange circuit 102-1 to be outputted as a main signal. On the other hand, a changeover device 2 is switched for each one field, and subtracts the output signal of the circuit 1-1 from an output signal by a subtracter 4. Further, it is converted into a passing scanning form by a successive/passing conversion circuit 102-2 to be outputted as an auxiliary signal. Thus, a successive scanning reproduction picture having 60 frame/sec. of the dynamic picture can be obtained with the same resolution as the still picture. The deterioration of the reproduction picture can be prevented even when connecting transfer signals, the transmitter-receiver can be standardized for each signal source, and no transfer of a discrimination signal is required.

IPC: H01L33/30
Filed: 1991-09-25
Abstract: PURPOSE:To provide a light emitting diode for a plastic communication fiber at a low price. CONSTITUTION:A mesa part 10 is made on a GaAs substrate by photolithography. An epitaxial layer, which constitutes junction, is grown on the substrate 8, where the mesa part 10 is made, by slide ball method. With the liquid-phase epitaxial growth method, if there is irregularity on the surface going to grow, the epitaxial layer seeks to grow into a recess. Therefore, the n-type GaAs current checking layer 7 of the first layer grows only in the section where a mesa part does not exist. Successively, the p-type GaAlAs clad layer 6 of the second layer, the p-type GaAlAs active layer of the third layer, and n-type GaAlAs clad layer of the fourth layer, the n-type GaAs contact layer 2 of the fifth layer are grown. After end of growth, an electrode 9 on p side, on the rear of a wafer, and an electrode on n side, on the surface, are formed by deposition and photolithography.
