Title: Radio equipment
Inventor: AOKI SABURO
IPC: H04B7/208
Filed: 1990-07-27
Abstract: PURPOSE:To attain efficient frequency channel assignment by providing a frequency channel sweep receiver to a control station so as to discriminate the presence of noise, disturbance and interference and controlling a frequency channel of a station to be controlled based on the discrimination information. CONSTITUTION:A frequency channel sweep receiver 2 sweeps frequencies f1-fn, to discriminate the presence of a reception signal and sends the discrimination information to a control station 1. Upon the receipt of a frequency channel request from a controlled station (n)3n, the control station 1 allocates a frequency fn-m to the controlled station (n)3n as a frequency channel while excluding busy frequencies f1, f2 and the frequency f3 because noise, disturbance and interference exist based on the information from the frequency channel sweep receiver 2. Thus, the efficient frequency channel assignment is attained.

Abstract: PURPOSE:To improve the heating operation capacity when frosted as well as the defrosting capability by a constitution in which the fin width is set in a certain range relative to the outer diameter of heat transmission pipe, the pitch of pipe winding that is normal to the air flow direction is made equal to the fin width, and the heat transmission pipe is wound in a row relative to the air flow direction. CONSTITUTION:A heat exchanger 10 comprises fins 11 which are equally spaced in parallel to allow the passage of air flow 13, and a heat transmission pipe 12 having the outer diameter D which is routed perpendicularly routed through the fins and carries a flowing fluid in it. The fin width L1 is set as 2.4D0<=L1<=2.7D0, and the pipe winding pitch L2 perpendicular to the air flow 13 is set as L1=L2. One row of the heat transmission pipe 12 is disposed relative to the air flow 13. Because the fin width L1 is 2.4D0<=L1<=2.7D0, the fin pitch FP can be widened, ensuring the a practically adequate heating operation capacity, and the heat exchanging quantity per unit cost can be maximized. Further, since the fin width L1 is equal to the vertical pipe pitch L2, the heat can be uniformly transferred from the heat transmission pipe 12 to the fins 11, improving the defrosting efficiency.

Title: Instrument for measuring surface shape of deposit in blast furnace
Inventor: NAKAMURA KOICHI
IPC: C21B7/24
Filed: 1984-09-26
Abstract: PURPOSE:To improve the accuracy in measuring the surface shape of the deposit in a blast furnace by using selectively >=2 kinds of lasers having different wavelengths according to the result of detecting the radiation level of a black body from the surface of the deposit part in the furnace. CONSTITUTION:The deposit 2 in the blast furnace is scanned by >=2 kinds of the lasers 3, 4 having the different wavelengths. If a long-wavelength laser having high output is used for the laser 3 and a short wavelength laser of low output for the laser 4, the photodetection output from the long-wavelength laser 3 is selected in a control circuit 5 and is processed in an arithmetic circuit 6. The temp. in the furnace rises and the black body radiation dominates, making difficult the identification of the scattered light. Such state is monitored by the output level of a sensor 16 such as radiation thermometer. The photodetection output is then changed over to the photodetection output from the laser 4 and is processed in the circuit 6. The surface shape of the deposit in all the states in the furnace is thus made measurable with high accuracy by the above-mentioned mechanism.
