Title: Method of cooling furnace wall refractory of industrial kiln
Inventor: KUNO YOSHINARI
IPC: F27D1/12
Filed: 1987-12-14
Abstract: PURPOSE: To prolong the service life of the furnace wall refractory of a kin by protecting the furnace wall of the kiln by arranging many L- or T-shaped copper cooling bodies in the refractories constituting the wall in such a state that the cooling bodies are brought into contact with the internal surface of a shell cooling wall with a brazing material. CONSTITUTION: The furnace wall of an industrial kiln is constituted of furnace wall refractory and many cooling bodies 8, with each cooling body 8 being composed of a heat radiating section 11 which comes into face-contact with a cooling wall 9 on the outer side of the kiln and a heat conducting section 10 which is positioned between refractory bricks 2 and extended from the heat radiating section 11. The shape of the section 11 is decided to follow the cooling surface of the shell of the kiln and the contact surface of the section 11 is formed in a flat or curved surface. The shape of the heat conducting section 10 is limited to a plate-like shape when the section 10 is put in the joint of the bricks, but can be selected freely when the bricks are worked or a monolithic refractory is used.  When the cooling bodies have a coefficient of thermal conductivity of 10 times and a cross-sectional area of 1/10 and are put between refractory bricks, the average coefficient of thermal conductivity of the refractory 2 becomes about 1.8 times. The cooling body can be made of a metal, ceramic, carbon, etc. In addition, in order to increase the heat radiating efficiency of the heat radiating sections of the cooling bodies, a brazing material is applied in advance to the heat radiating surfaces of the cooling bodies.

Title: Aluminum alloy welded joint excellent in toughness at low temperature, and structural material using same
Inventor: HAYASHI MINORU
IPC: C22C21/06
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To obtain a welded joint excellent in toughness at very low temperature and most suitably used for a structural material for storage/transportation of liquid hydrogen or the like by specifying the amount of Mg contained in the weld metal zone of a welded joint and further specifying average crystalline gran size. SOLUTION: This welded joint contains a weld metal zone consisting of, by weight, 1.5-<3.5% Mg and the balance Al and further having <=200 μm average crystalline grain size or contains a weld metal zone consisting of, by weight, 1.5-<3.5% Mg, one or more kinds among 0.05-l.0% Mn, 0.05-0.5% Cr, 0.05-0.5% Zr, and 0.05-0.5% Ti, and the balance Al and further having <=200 μm average crystalline grain size. Since the strength of grain boundaries as well as the occurrence of deformation within a grain can be improved even at low temperatures by limiting the amount of Mg to values in the above range, crystallization of β-phase (Al3Mg2) as well as segregation of Mg into grain boundaries can be prevented and ductility/toughness value at very low temperatures can be greatly improved.

Abstract: PURPOSE:To facilitate operation and to easily and speedily perform the operation by operating operation switches of a measurement part for plural persons at a time, and selecting a memory and taking a measurement. CONSTITUTION:A user operates one switch in the switch group at the measurement part to enter measuring operation. The controller of the measurement part performs measurement until a user gets down from a weight measurement bench, and keeps on sending measurement data to the reception part 18 of a display part by a transmission part. Then the display part quits a time display on an LCD display part 20 first and determines a zero point according to the data. Simultaneously, the display part 20 displays past data based upon a code No. The buzzer of a buzzer circuit part 17 indicates that the user may gets on the measurement bench after the determination of the zero point. Then the weight is displayed on the display part 20 in real time until data becomes stable and the weight is determined. When the body weight is determined and the user gets down from the measurement bench, the difference from a stored last value is calculated and displayed on the display part 20 alternately with the determined weight.

Title: Tightening body
Inventor: SAKAMOTO ATSUSHI
IPC: G01L5/00
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To detect the looseness of a screw in a practical use condition without specially machining the screw by measuring electrical resistance or heat resistance across the screw and a tightened body or across tightened bodies, and detecting the change of the resistance value. SOLUTION: Fine irregularities exist on a machined surface, and the projection and recess thereof are in contact with each other on contact surfaces. When contact pressure increases, a contact area increases or a new contact projection appears, due to the elastic or plastic deformation of the projection in contact with the recess. On the contrary, the contact area decreases, when the contact pressure drops. Electrical or heat resistance across the contact surfaces is correlated to the contact area and resistance drops according to an increase in contact area. In this case, therefore, an electrical resistance measuring device 5 is laid and terminals are connected to a screw (male screw 1 and nut 2) and a tightened body 3 or 4, or tightened bodies 3 and 4. Then, electrical resistance across the terminals is measured.  The same process applies, when a plurality of tightened bodies exist, or the tightened body is internally threaded.

Title: Reversible motor driving controller
Inventor: YAMAURA MASASHI
IPC: E05F15/695
Filed: 1990-11-20
Abstract: PURPOSE:To simplify an operating part by a method wherein, if a same type operation signal as an operation signal inputted at a previous time is successively inputted at a predetermined time after the input of the previous operation signal, a motor is stopped when the second operation signal vanishes. CONSTITUTION:If an operation signal of a same direction as a signal inputted at a previous time is inputted before a timer T2 ends, a motor 2 is driven to that direction and it is immediately checked whether a timer T1 has ended or net. If the timer T1 has ended, the motor 2 is cut off at that time. If the timer T1 has not ended, an automatic mode operation is introduced and the motor 2 is driven continuously until the timer T1 ends or lock/open following the discrimination of current values is detected. Further, if an operation signal of the same direction is inputted for the third time, the timer T1 is restored and a manual mode operation is recovered as a first time switching input corresponding to respective motor driving directions.

Title: Porous material for water purification, deodorization, sterilization and insect proof
Inventor: SUZUKI YUKIO
IPC: B01J20/02
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To obtain a porous material for purifying water being high in water purifying effect and usable to large scale water purification without affecting others by using a shell-calcined material as a water purifying agent. SOLUTION: Oyster shells as an example, are crushed and calcined at about 400 deg.C. About one kg of the materials is packed in a net bag and put in a water tank with water bloom generated, then the transparency of water is examined every one month. A non-calcined material simultaneously crushed and left as it is for about one year, is used in the same manner as a comparative example. The transparency of water of both materials is compared. Namely a dipper-shaped seeing through degree measuring instrument 1 having an about 50mm diameter disk with a white color ground on which the figure eight is written with black color in an about 30mm diameter of circle, is used and the depth enabling to read the figure is measured to compare. In a water thank not containing anything, the transparency remarkably decreases when it passed for about three months from propagation of the wager bloom.  The transparency of the water tank charged with uncalcined oyster shells is increased by about 280mm depth after five months. While the transparency using the calcined shells is by about 550mm depth. Thus, water purification work is enhanced by calcining the shells.
