Title: Small ceiling precast block for electric furnace
Inventor: SOEDA TOMOMI
IPC: F27D1/04
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To improve the periphery of an electrode hole while ensuring safety of the body by arranging a precast block of Al2 O3 -MgO containing a specified wt.% of MgO around the electrode hole in the small ceiling of an electric furnace and arranging a precast block of Al2 O3 -SiO2 at other parts of the body. SOLUTION: A precast block of Al2 O3 -MgO containing 1-30 wt.% of MgO is arranged around the electrode hole 2 in the small ceiling 1 of an electric furnace and a precast block 3 of Al2 O3 SiO2 is arranged at other parts of the body. More specifically, MgO is added to Al2 O3 excellent in melting loss resistance and heat resistance and employed as a material on the periphery of the electrode hole 2. As a result of basic experiment performed with a specified compounding ratio on a table in order to determine the quantity of MgO to be added, corrosion resistance was not enhanced when MgO is 1 wt.% or less and spalling resistance dropped through thermal expansion of MgO and reaction of Al2 O3 and MgO for producing spinel.

Title: Color picture reader
Inventor: KOMATSU KATSUAKI
IPC: H04N1/46
Filed: 1991-04-22
Abstract: PURPOSE:To obtain correct color information from which a picture with high saturation and sharpness is obtained by compensating deformation of a diffraction image due to diffraction and deviation of a sensor array so as to eliminate a cause to color ghost. CONSTITUTION:A reflected light from an original lighted by a light source is dispersed into a 0-th light and + or -1st lights by using an image forming lens and a diffraction grating in which the thickness of a transparent base is stepwise and repetitively changed and the dispersed light is read by using a 3-color line sensor 4 comprising 3-color sensor arrays. Then deviation in the diffraction image corresponding to a field angle of each sensor is compensated by a memory 44 and an arithmetic circuit 43. That is, since the 0-th light in the diffraction light is not diffracted, the center sensor array and the image are coincident and the image is not coincident with the sensor array including the 1st lights, the memory circuit stores preceding signals for 1-3 periods of the scanning and the signal is outputted to the arithmetic circuit 43, in which the arithmetic processing is implemented to compensate the deviation.

Title: Control circuit for variable impedance circuit
Inventor: KANEKO AKIO
IPC: H03G3/04
Filed: 1981-06-12
Abstract: PURPOSE:To control plural variable impedance circuits with just a single variable resistor, by using a coincidence detecting circuit to detect whether the output of a resistor is coincident with the output of a hold-through gate and setting the hold-through gate in a through-mode when the coincidence is obtained with the above-mentioned comparison. CONSTITUTION:When the circuit changeover switches S4 and S5 are turned on and off, a flip-flop circuit (FE)5 is shifted to an input queuing mode from a clear mode. The output voltage of a variable resistor 1 is controlled, and the output held at a hold-through gate 24 becomes equal to the output of the resistor 1. Thus a pulse is applied to the input terminal of an FF5 from a comparator 3, and the output of the FF5 is changed to a low level from a high level to be used as a control input of the gate 24. The gate 24 is set in a through-mode. As a result, the resistor 1 is coupled to a variable impedance circuit 9 to perform the volume control. The operation of the switches S4 and S5 is reversed for the tone control, and a gate 24' is set in a through-mode.

IPC: G01N21/88
Filed: 1979-07-17
Abstract: PURPOSE: To improve the certainness of hot flaw detection by differentiating a video signal from a television camera, by correcting a reference decision level by the mean value of the differential signal, and then by comparing the differential signal to the reference decision level.  
     CONSTITUTION: A video signal stored in video memory unit 3 is sent to differentiator 42 by way of synchronous separator 41 and, after being differentiated, sent to comparator 43. This differential signal is also rectified by positive rectifier 45 and negative rectifier 46, integrated by integrators 47 and 48 respectively and then sent to comparator 43 to correct a reference decision level. Comparator 43 compares the differential signal from differentiator 42 to the corrected reference decision level and then sends the result to synchronous superposing unit 44 and adder 49. Synchronous superposing unit 44 superposes synchronizing signal α from synchronous separator 41 and sends the obtained signal to flaw-position detector 5, which detects a flaw position. Further, adder 49 adds a video memory signal from video memory unit 3 and sends the sum signal to monitor 8 to project it. Thus, the certainness of hot flaw detection is improved.

Title: Granular agricultural chemical
Inventor: SHIMIZU HIROMICHI
IPC: A01N25/12
Filed: 1983-05-24
Abstract: PURPOSE:To obtain granular agricultural chemical which is solid at normal temperature, having decreased tendency of agglomeration with time and improved storage stability, by using a lactone, especially epsilon-caprolactone as a component. CONSTITUTION:The objective granular agricultural chamical contains 100- 300pts.wt. of a lactone (especially epsilon-caprolactone) per 100pts.wt. of the active component. Since the agglomeration of granular agricultural chemicals occurs frequently when the melting point of the active component is 15-160 deg.C, the addition of lactone is most effective in the gruanular chemicals containing the active component having the above melting point. Furthermore, the granule prepared by the coating granulation process has high concentration of the active component at the surface of the granule, and the addition of lactone is extremely effective. The granular agricultural chemical having reduced aggromeration tendency with time by the addition of lactone has high flowability, and can be readily scattered in the field.
