Title: Semiconductor optical element
Inventor: KUROBE ATSUSHI
IPC: G02F1/015
Filed: 1987-03-25
Abstract: PURPOSE:To suppress the spread of the light absorption peak of a multiple quantum well structure and to provide the improved performances such as increased extinction ratio of an optical amplifier and reduced electric power consumption of an optical bistable element by taking the forbidden band width of the quantum well positioned in a high electric field part larger than the forbidden band width of the quantum well existing in a low electric field part. CONSTITUTION:The energy shift quantity by the wavelength increasing of the exciton absorption peak by electric field impression depends highly on the quantum well width Lw in the form of Lw<4>. The effect of spreading the absorption peak by the nonuniform electric fields in the respective quantum wells is, therefore, suppressed if the energy shift quantity of the quantum well impressed with the high electric field is decreased by reducing the width thereof and if the energy shift quantity of the quantum well impressed with the low electric field is increased by increasing the width thereof. The quantization level of this time changes as well. The spread of the absorption peak occurring in the nonuniform electric fields which is generated when the element is reverse biased to the element operating potential is thus eliminated by taking both into consideration.

Abstract: PURPOSE:To obtain a red mud granule which has no adhesive strength and is rigid by granulating hydrous red mud cake while adding >=1 kind coal factory dust, coal ash, coke ash, soot or dry red mud thereto on the verge of ending of the granulation. CONSTITUTION:The red mud slurry discharged from an alumina production stage is filtered to 9.3wt% stuck moisture with a press filter, whereby red mud cake is obtained. The red mud cake is put in a tray type granulator having 2.8m inside diameter and 0.55m depth, and the granulator is operated at 9rpm and 43 deg. angle of inclination. The red mud cake is thus granulated while 3wt% lime factory dust basing on the weight of the supplied red mud is added thereto. The lime factory dust to be added in this stage is mixed with the red mud at around the time when the red mud is removed from the granulator after granulation. The red mud which is difficult to handle is granulated to the rigid grnules having no adhesive strength by the above-mentioned method and the granules are handled easily when the granules are to be utilized in various applications thereafter.

IPC: G11B5/48
Filed: 1982-04-27
Abstract: PURPOSE:To attain the detection of a desired single track with good accuracy, by using a magento-resistance effect element as a detection element, oscillating a vertical axis to a recording track as the node of oscillation at reproduction, and contacting the detection section on plural recording tracks. CONSTITUTION:A reproducing head 1 is constituted by arranging an MR element 3 on a plane opposing to a magnetic recording medium 5 under a base 10 constituted with a raw material deformed with the electrostriction. A head 1 is arranged vertically so that a center line 4 comes on a desired recording track 54 on a magnetic recording medium 5 having plural recording tracks 51-56. The base 10 is oscillated by taking the center line 4 as a node with the principles of the electrostriction at reproduction. An output from the detection section 3 reproduces the signal of the recording track 54 normally, but the signals on the other recording tracks are averaged for the magnetic field of each track with the oscillation of the reproducing head 1 and act like noise. Thus, the detection of the desired single track is attained with good accuracy.

Abstract: PURPOSE: To enable the immediate detection of filament snapping of a lamp through a simple construction, by connecting dummy diodes and a resistor to a no-lamp part of a lamp matrix, detecting the abnormal potential of a current circuit and turning on an indicator lamp.  
     CONSTITUTION: When an indicator 1 for indicating a turned-on lamp shows "0, 1, 1, 0", transistors Qb, Qf along axes X, Y are turned on through decoders 2a, 2b to supply an electrical current to the lamp LD22 connected at an intersection as to the axes X, Y to turn on the lamp. If the filament of the lamp snaps, the potential on the plus input of a sense amplifier 4 rises. Therefore, the potential is compared with a reference potential VREF. If the potential is higher than the reference potential, a lamp filament snapping flag 5 is set and a light emitting diode LDa for indicating the snapping of the lamp filament is turned on by a driver 6. A series circuit consisting of the dummy diodes D11, D43, D44 and the resistor r is coupled to each intersection with no lamp to distinguish between the filament snapping of the lamp and its absence.

Abstract: PURPOSE:To improve the attenuation of near-end crosstalk with out reference to an increase in insertion loss, by composing an optical branching filter of an optical filter and >=2 kind of optical media differing in refractive index. CONSTITUTION:In an optical branching filter 5 of a two-wavelength duplex multiplex transmission system which uses 2 kinds of light emitting diodes having different band spectra 21 and 22 as light sources, the optical path wherein transmitted light after passing through a filter 6 propagates until a photodetecting terminal 7 is composed of 0.08/mum wavelength dispersion optical glass 8 and 0.02/mum wavelength dispersion optical glass 9, for example, and signal light reaches the photodetecting terminal 7. The optical glass 8 and optical glass 9 are not bonded together. If light incident to the filter 6 is at 14 deg. and the length of the optical path is of 20mm., the arrival position of unnecessary light, causing near-end crosstalk, at the photodetecting terminal 7 is shifted by about 30mum. Therefore, the attenuation of near-end crosstalk is improved without entailing an increase in insertion loss.
