Title: Method for sealing inner cover of box type annealing furnace for grain oriented magnetic steel sheet
Inventor: HIRASHIMA KOICHI
IPC: C21D9/46
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent the raising of dew point in an inner cover by sealing with a two layer structure of a spherical body material having a specific diameter as the lower layer and coarse grain seal material having a specific value of the average grain diameter. SOLUTION: The spherical body seal materials 2-2 having 5-30mm diameter are spread all over a seal plate 3. Conventionally used aluminas having e.g. 0.5-2mm grain diameter are spread all over on the spherical body seal material 2-2, as the coarse seal materials 2-1 at about 20mm thickness. The coarse seal materials 2-1 are filled up into the gaps among the spherical body seal materials 2-2. The inner cover 1 is laid on the coarse seal materials 2-1. The spherical body seal materials 2-2 are interposed between the seal plate 3 and the lower end surface of the inner cover 1, and the gaps are always secured. Since the lower end surface of the inner cover 1 and the spherical body seal material 2-2 are in point-contacts, the flow of atmospheric gas is not interrupted.  In the case of being <5mm diameter of the spherical body seal material 2-2, there is such danger as to push up the seal material 2-2 by fluid action during the operation.

Title: Nozzle for pouring molten metal to continuous casting machine
Inventor: HORIGUCHI MINORU
IPC: B22D41/50
Filed: 1983-10-26
Abstract: PURPOSE:To provide a titled nozzle which decreases the inward deflection and tensile stress in a wall owing to thermal expansion and deformation, prevents the crack of a nozzle for pouring a molten metal having a broad sectional shape and assures safe operation for long time by making the central part of the thickness of the long side wall of said nozzle larger toward the outside. CONSTITUTION:The molten metal 7 in a tundish 1 is fed from a nozzle 2 for pouring a molten metal having a broad section with water cooling 5 to a water spray 9 and a guide roller 10 part through a force cooling body 4. The long side 16 of the nozzle 2 is restrained by a short side 17 and is deflected inward by thermal expansion, by which the width size is changed and a crack is generated in the long side 16 of the nozzle. Compressive stress and strain are proportional to the square of the length of the side and are inversely proportional to the thickness. The thickness tc in the central part of the long side 16 is therefore made larger than the thickness tn at the end, by which the deflection is decreased to a specific value or below and the tensile stress by the thermal expansion is decreased to prevent the generation of the crack. The life of the nozzle 2 is extended by such shape and the safe operation free from water leakage, etc. is accomplished.

Title: Developing device
Inventor: ITOU YOSHIO
IPC: G03G15/08
Filed: 1981-12-10
Abstract: PURPOSE:To prevent the operation errors of an automatic concn. regulator ATR by protecting an ATR detecting element which detects the change of electrostatic capacity, etc., in the surroundings against the disturbing magnetic field from  a magnet disposed in a sleeve by means of magnetic material shields. CONSTITUTION:Level detection is accomplished by detecting the capacity of the developer. When the developer contg. iron power as a carrier and a toner decreases to a position lower than the height of an ATR element 23, the element  23 detects the change in the electrostatic capacity or magnetic field near the  element and replenishes the toner to the developer through a hopper. In this case, important is that a magnet 3 exists near the element 23. Therefore, the  magnetic field that give disturbance must be shut off. Shield plates 6-7 are the  magnetic shield walls constituted of a magnetic material, and the disturbing  magnetic field from the magnet 3 is shielded against the element 23 by means  of these shield plates. Thereby, the operation errors of the automatic concn. regulator is prevented and the concn. regulation of the developer is accomplished  well.

Title: Robot control system and its remote work instructing method
Inventor: TANAKA SHUJI
IPC: G05B19/414
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To shorten a waiting time for outputting a second work instructing signal after a first work instructing signal is outputted by causing a remote control operation terminal to permit transmission of a work instructing signal to be sent next after the terminal receives a reception signal. SOLUTION: When a remote control operation terminal T1 transmits a first work instruction signal, a robot controller CT1 receives this signal to transmit a receiving signal, then the remote control operation terminal T1 immediately receives this signal and displays its receiving on a display or the like and, at this time, tying with the robot controller CT1 is started. In other words, a second work instruction signal is transmitted without waiting for the operation end of a robot RM. Then, after the operation of the robot RM is completed, the remote control operation terminal T1 receives a work end signal from the robot controller CT1 and the work end of the robot RM is displayed on the display of the remote control operation terminal T1.

Title: Heat transfer tube for condensing within tube and manufacture thereof
Inventor: OTANI TADAO
IPC: F28F1/40
Filed: 1988-08-10
Abstract: PURPOSE:To smoothen the flow of liquefied refrigerant, restrain the raking up phenomenon of the refrigerant solution remarkably and increase condensation heat transfer rate particularly by forming parallel grooves, which are parallel to the axial direction of a tube, and orthogonal grooves or slanted grooves, having an angle between the parallel groove, on the internal surface of the tube. CONSTITUTION:The flow of the vapor of refrigerant in a heat transfer tube 10 is changed into turbulent flow by slanted grooves 1, 1 and is condensed while developing excellent heat exchanging efficiency while refrigerant solution, liquefied by the condensation, flows down along the slanted grooves 1, 1 and is stagnated at the lower part of the heat transfer tube 10. Parallel grooves 2, 2 are formed on the lower side of the heat transfer tube 10 and the refrigerant solution, liquefied and condensed, can flow in the parallel grooves 2, 2 very smoothly whereby a behavior, such as comb-up phenomenon of the refrigerant solution which is generated in spiral grooves, will never be generated. Accordingly, the possibility of unnecessary wetting of the wall surface in the tube by the refrigerant solution and the remarkable deterioration of heat transfer efficiency may be eliminated sufficiently by the smooth flowing. According to this method, the miniaturization of the heat exchanger or the miniaturization of a refrigerant device may be achieved and the cost of installation or running cost may be reduced.

Title: Pulse width modulation a/d converter
Inventor: ANDO YUKIKIYO
IPC: H03M1/44
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To unnecessitate resistance which is high accuracy and high resistance and to enable integration by changing the resistance of an integrator to charge transfer elements consisting of a switching means and a condenser. SOLUTION: Charge transfer elements 11 to 13 consist of switching means SW1 to SW3 and condensers C1 to C3 respectively. Relating to the elements 11 to 13, a clock signal rises and a ϕ1 side is turned on before a ϕ2 side is turned off and the ϕ1 side is turned on when the ϕ1 side is off and the ϕ2 side is on. The clock signal falls and the ϕ2 side is turned on before the ϕ1 side is turned off and the ϕ2 side is turned on. Such operations are repeatedly performed. Thereby, when both the ϕ1 and ϕ2 sides are off, it is possible to prevent operation noise of digital circuits (a flip-flop 4, a microprocessor 5 and a counter 7) from being mixed to charges of the condensers C1 to C3 and to perform A/D conversion with high accuracy by performing the fall and rise of a clock signal.
