IPC: C22B34/32
Filed: 1980-08-05
Abstract: PURPOSE: To reduce Cr and Fe oxides in powdered Cr ore to carbides in a solid phase at a superior reduction rate by heating a mixture of the ore with a liq. or solid agent in a fluidized bed reactor while fluidizing it with gases.  
     CONSTITUTION: A reducing gas as CO or H 2  and an inert gas such as N 2  are blown from a gas feeding inlet 3 of a fluidized bed reactor 1, and powder of Cr ore and a liq. reducing agent such as heavy oil or a solid carbon reducing agent such as slack coal are fed from an upper feeding inlet 2 and an inlet 5, respectively. While maintaining the internal temp. of the reactor at a relatively low temp. such as 1,100W 1,300°C, a fluidized bed 4 made of mixture of the Cr ore powder with the liq. or solid reducing agent is formed with the blown gases. Cr 2 O 3  is reduced to Cr 4 C, etc. with carbon formed by the thermal decomposition of heavy oil or solid carbon of slack coal in a solid phase, and FEO to Fe 3 C, etc. with CO, H 2  and solid carbon. Thus, the Cr ore is preliminarily reduced at 50W60% reduction rate.

Title: Optical disk
Inventor: NISHIDA YASUHIDE
IPC: G11B7/24073
Filed: 1990-04-23
Abstract: PURPOSE:To improve a track density without changing the lens and laser of an optical disk memory device by providing a difference in height by as much as the wavelength of 1/4 the laser wavelength and neighbouring value for reproducing or the approximate value thereof on the recording surfaces of adjacent two tracks on both sides of one track. CONSTITUTION:The adjacent tracks TR(n-1) (n+1) are also irradiated with the laser beam LSR and the reflected light ray based thereon are generated if the diameter of the laser beam BM for irradiation is larger than the intertrack spacing of the optical disk 10. The reflected light from the (n-1) track TR of the reflected light rays from the tracks TR(n-1) (n+1) advances in phase nearly by pi/2 and the reflected ligh from the (n+1) track TR delays in phase nearly by pi/2 if the reflected light from the n track is assumed to be a center. The reflected light rays from the (n-1) track TR are, therefore, shifted eventually by nearly pi in phase. These reflected light rays are negated by each other and crosstalks are consequently decreased. The track density is improved in this way without replacing the lens and laser to be used.

Abstract: PURPOSE:To easily eliminate noise by generating binarized reproducing data from the AND between a gate signal obtained by comparing and selecting the amplitude level between a reproducing signal and its delayed signal and a zero-cross signal obtained by differentiating and detecting the reproducing signal. CONSTITUTION:The amplitude level between the reproducing signal and the delayed signal obtained by delaying the reproducing signal for a prescribed period of time by delay elements 1 and 2 is compared in a comparison and selection circuit 4. A noise component is eliminated by selecting one of these signals with smaller amplitude level, and a gate signal binarized in a gate pulse circuit 5 is outputted to an AND circuit 7. On the other hand, a differenting circuit 3 differentiates the delayed signal of the element 1, and a zero-cross comparator 6 generates a zero-cross signal indicating the peak position and outputs it to the circuit 7. The circuit 7 outputs the binarized reproducing data whose noise component is blocked by taking the AND between the gate signal and the zero-cross signal. Thus, the noise of the reproducing signal can be eliminated with a simple circuit and a demodulation error can be reduced.
