Title: Preliminary reduction furnace with fluidized bed for powdery and granular ore
Inventor: HAMADA SHIYUNJI
IPC: C22B5/02
Filed: 1982-12-20
Abstract: PURPOSE:To prevent powdery and granular ore from being discharged together with waste gas and to prevent the decrease in the yield of the ore by providing a rotary type separator in the freeboard part in a preliminary reduction furnace with fluidized bed for the powdery and granular ore. CONSTITUTION:Powdery and granular ore 2, such as powder iron ore, is put in a preliminary reduction furnace with fluidized bed, and reducing gas of a high temp. is blown up from a gas diffusion plate 3 at the lower part. The fluidized bed of the ore 2 is formed by the ejected gas, by which the ore is preliminarily reduced. The waste gas is discharged from a discharge port 10. A separator 12 consisting of an outer frame 12a having vanes 12b rotating at a high speed by a shaft 12C is disposed in the freeboard space 9 above the fluidized ore layer in such device. The separator 12 is rotated by the ascending waste gaseous flow in the furnace, then the powdery ore contained in the waste gas collides against the vanes by which the powdery ore is scattered horizontally until it collides against the frame 12a. The powder colliding against the falls by losing the velocity and is thus prevented from being discharged together with the waste gas from the port 10, whereby the decrease in the yield of the ore is prevented.

Filed: 1985-10-07
Abstract: PURPOSE:To attain data transmission with high efficiency and high reliability even to transmission line disturbance or reception station busy state by providing a field in which information whether or not requesting the sending of a reply code from a transmission state to a reception station is written to a frame so as to increase the utility of the transmission line. CONSTITUTION:The reception station 1 detects the logical level of a reply request flag F included in a frame FS sent from a transmission station 2 via a transmission line 3, and an affirmative reply code ACK is inserted in response to the logical level at the data reception or the frame FS is changed into an idle frame and the result is sent to the transmission line 3. When the data reception is disabled, a negative reply code NAK is inserted independently of the logical level of the reply request flag F and the result is sent to the transmission line 3. Thus, an unnecessary reply frame is less on the transmission line 3 and the transmission station side supervises the negative replay code NAK to apply retransmission control so as to attain quick correspondence and the data transmission with the high efficiency and high reliability is realized.

Abstract: PROBLEM TO BE SOLVED: To obtain high ratio for a peak current to a valley current radio, without decreasing peak current density by inserting at least two positive hole barrier layers which become barriers to positive holes of a first, a second and a third semiconductors, in a quantum well layer. SOLUTION: For example, GaAs positive hole barrier layers 105, 107 are made 0.6nm in thickness. A GaSb quantum well layer 104 between a first barrier layer 103 of AlSb and the GaAs positive hole barrier layer 105 is made 4.5nm in thickness. Peaks of resonance tunnel probability that electrons in an InAs emitter layers 110 reach an InAs collector layer 102 are bundled, and the half band width does not becomes smaller than the half band width of the peak of resonance tunnel probability in the conventional structure for the same AlSb barrier width. The half band width of the peak of the resonance tunnel probability may be considered to be approximately proportional to the peak current density. Thereby the peak current density of an element does not become lower than that of the conventional structure.

Title: Semiconductor light-emitting device
Inventor: KAKIMOTO SHOICHI
IPC: H01L31/12
Filed: 1987-09-04
Abstract: PURPOSE:To obtain an excellent noise characteristic by installing the following: a laser diode which emits a laser beam from a front face and a rear face; a photodiode which is arranged on the side of its rear face and which has a concave part used to reflect one part of the laser beam emitted from the rear face and to converge the beam to one point. CONSTITUTION:A surface 15 of a photodiode 14 has a concave curvature; it absorbs one part of a beam emitted from a rear face 3 of a laser diode 1; it reflects and returns a remaining part to the laser diode 1 so that the remaining part can be converged to one point. In this way, an axis mode to always return a reflected beam to the laser diode is a multiple mode whose wavelengths differ individually; in the laser diode of the multiple mode, the axis mode is not changed by a change in a temperature or a change in an impressed current; in addition, as compared with a single-mode laser, a wavelength of an oscillation axis mode is not changed even when a beam is returned from an optical system; a phenomenon such as a concurrent noise due to a jump of a mode is not caused. As a result, a noise characteristic is not deteriorated extremely; a stable S/N ratio with a definite output is obtained.

Abstract: PURPOSE: To provide a radar apparatus which is not disturbed easily while the detection capability of a moving target is being maintained. CONSTITUTION: By a transmission trigger from a timing generator the a frequency controller 2 generates a control signal changing the frequency in a definite sequence or randomly, and it changes the oscillation frequency of a high-frequency oscillator 3. Its high frequency and a reference signal from a reference-signal generator 4 are mixed by a mixer 5. A mixed signal is changed into pulses by a transmitter 6, it is sent out form an antenna 8 via a transmission-reception changeover device 7, and its reflected signal is captured through the antenna 8. The captured signal is input to a receiver 9 via the transmission-reception changeover device 7. A coherent video signal is generated by the high-frequency signal and the reference signal so as to be stored sequentially in a memory by a signal processor 10.  In a period in which a video signal of the same frequency as the signal is input, the video signal which has been stored in the memory is read out. The difference signal between both signals is found, and the Doppler frequency shift, i.e., a moving object, is detected.
