Title: Continuous casting machine for metal
Inventor: YOSHIZAWA ISAMU
IPC: B22D11/06
Filed: 1984-07-31
Abstract: PURPOSE:To produce a steel ingot having a large thickness without having surface flaws and without inducing troubles such as leakage of a molten metal in the stage of casting continuously the molten metal with a twin-roll type continuous casting device, etc. by providing heat resistant rolls above twin rolls in tight contact therewith and forming a pouring basin for the molten metal by two sets of said rolls. CONSTITUTION:The heat resistant rolls 6, 6 are rotatably disposed above the cooling rolls 1, 1 of the twin-roll type continuous casting device. The molten metal 3 supplied from a tundish 2 enters the pouring basin constituted of both roll sets 1, 1 and 6, 6 and therefore the distance (l) at which the molten metal 3 contacts with the surfaces of the rolls 1, 1 increases. The production of the steel ingot 4 having the large thickness is thus made possible by an increase in the (l) to control the thickness of the ingot 4. The rolls 6, 6 above the rolls 1, 1 rotate in tight contact with the rolls 1, 1 and therefore there is no leakage of the molten metal. The formation of flaws on the surfaces of the rolls 1 as a result of friction with a gate frame 5 and the consequent deterioration of the quality of the ingot 4 surface as in the case of providing the frame 5 are obviated.

Abstract: PURPOSE:To establish a method of preventing smoke dispersion and securing the safety of an evacuation path by selecting the position of air supply/exhaust hole and controlling the air supply and exhaust when a fire has broken out in an indoor space with wide expanse. CONSTITUTION:When a fire breaks out from a firing part 17 in a large indoor space 7, a fire sensing means 15 senses it, and a control device 30 opens opening/closing valves 24a, 12a in an upper and a lower exhaust hole 24, 12 and the smoke layer 26 is released into the atmosphere due to the temp. difference between the layer 26 and the outside air or moved toward the uppermost part of the space. After the smoke layer 26 is released or lifted, a safety checking means 28 makes sure the unmanned condition, and thereupon the valve 24a in the upper exhaust hole 24 is blocked to lessen air feed to the combustion area of the firing part 17 to promote extinction. Upon making sure that the smoke layer 26 has moved to above a fire extinguishing facility 31, it conducts extinguishing works in the lower space which must be used for evacuation.

Title: Method for switching os (operating system)
Inventor: KURIYAMA KAZUYA
IPC: G06F9/46
Filed: 1987-06-29
Abstract: PURPOSE:To quickly execute switching by allowing kernels of plural OSs to be resident in a main storage, inputting an interruption to a processor at the time of switching the OS, reserving a data of an operation environment of the OS before switching, in a secondary storage, and also, reading out the data of the operation environment from a secondary storage. CONSTITUTION:Kernels 14, 16 of plural OSs (Operating Systems) are stored in a main storage, and at the time of switching the OS, an environmental data of the present OS is reserved in a secondary storage, and also, an environmental data of a new OS to be switched is read out of the secondary storage and reset. Therefore, since the kernels 14, 16 are resident in the main storage, switching is executed quickly. Also, the environmental data of the OS is reserved, read out again and reset, therefore, when the OS has been returned to its origin, the previous work environment can be continued, and it is unnecessary to set newly the environment. Moreover, since the environmental data is saved in the secondary storage, it does not occur that an area of the main storage becomes narrow, and many applications can be executed.

A straight guide part 6 is formed in parallel at the inlet 5, and a colliding wall 7 slanting downward is installed ahead of the guide part 6. This enables colliding of exhaust gas, fed through the inlet 5 and advancing straight in a direction A along the guide part 6, with the colliding wall 7 to creat a turbulence to form a turbulence range 8. A burner nozzle 9 faces the combustion chamber 3 in a manner to point to the turbulence range 8, exhaust gas within the tubulence range 8 is burned by a combustion flame from the nozzle 9 to incinerate an offensive and harmful component, and thereafter the exhaust gas is exhausted through an exhaust port 11.

Abstract: PURPOSE: To stop a core wire in compliance with the interruption of power supply and previously prevent the defects of weld zone by connecting a variable resistance in series to a core wire supply motor when MIG welding is stopped.  
     CONSTITUTION: A DC shunt motor 1' is used for a core wire supply motor 1, and the armature winding of the motor 1' is connected to a DC power source 12 via a switch 11 upon starting of welding. Then, the motor 1' rotates and causes a core wire 3 to be drawn out from a winding frame 4 by rollers 2. The wire is then supplied through a welding nozzle 5 to the groove 7 of base material 6, and electric power is supplied between the core wire 3 and the base material 6 from a power source 8. When the welding is stopped, the switch 11 changes over and the revolving energy of the motor 1' is consumed by a variable resistance 13. At this time, the resistance value of a variable resistance 13 is controlled to regulate braking force so that oversupplying or undersupplying of the core wire 3 is prevented from occuring.

Abstract: PURPOSE:To reduce remarkably the noise generated in converting a PCM signal into a voice through a line such as a communication line by converting the voice into the PCM signal in a manner that a zero code output is outputted as a positive or a negative zero code only. CONSTITUTION:An offset generating circuit 5 and switches 6, 7 are provided in addition to a conventional PCM signal coder composing of a comparator 2, a sequential comparison register 3 and a local decoder 4. Since the PCM signal coder, different from a conventional PCM coder of a conventional murule in deciding the polarity bit, decides the polarity bit based on -X1, the negative zero code output of (01111111) is not outputted, but only the positive zero code of (11111111) is outputted.

Title: Sentence editor
Inventor: ARAI TSUNEICHI
IPC: G06F17/24
Filed: 1987-07-01
Abstract: PURPOSE:To efficiently edit a required sentence by judging the writing format of inputted sentence information and allowing an edition control means to execute the edition processing of the sentence information whose edition mark is specified based on the decided result. CONSTITUTION:A hand-written pattern recognizing device 1 analyzes a hand- written pattern on a tablet or the like based on prescribed algorithm and outputs the analyzed result to a CPU 2. The CPU 2 writes the analyzed pattern code in a RAM 3b and displays a character font corresponding to the pattern code from a RAM 3a on a character display device 4 correspondingly to an input coordinate vale. Since the CPU 2 judges that the input sentence is vertically or horizontally written format by referring the RAM 3b, edition such as one- character insertion or one-line insertion is executed in accordance with an edition mark specified on the hand-written pattern based on the decided result. Consequently, sentences can be edited by the common edition mark independently of the writing format.

Title: Catalytic combustor
Inventor: MATSUMOTO IKUO
IPC: F23D14/18
Filed: 1981-10-12
Abstract: PURPOSE:To reduce the danger of back fire, and to widen the range capable of catalytic combustion by forming a through-port with a large opening area at the fuel charging side of a catalyst body and a through-port with a small opening area at the exhaust-gas discharge side. CONSTITUTION:A catalyst body 1 for catalytic combustion consists of porous alumina sintered bodies, the through-ports 3 take truncated cone form, and the opening area at the fuel charging side 4 of the catalyst body 1 is large and the opening area at the exhaust-gas discharge side 5 of the catalyst body 1 is small in the through-ports 3. According to such constitution, a fuel gas passes at considerably fast speed at the point of time when the fuel gas enters the through- ports 3 of the catalyst body 1 first. Consequently, the temperature of the fuel inflow side 4 of the catalyst body 1 is not easily elevated because contact areas are small and heat generated is backward carried away by an air flow at fast speed in the quantity of heat heat-generated through an oxidation reaction in the vicinity of the through-ports, thus preventing the transfer of the back fire in the direction of the inflow of fuel.
