Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To make free the direction of a deep pan placed on a top plate, improve the convenience in handling, prevent the deep pan from side slip and falling off, and heighten the safety by fitting a circular guard slidably in a groove formed on the top plate or a resin case of the cooking apparatus. SOLUTION: The body of a cooking apparatus 10 has a groove provided on a top plate 11 in a circular form made of ceramic glass or a resin case to which the top plate 11 is adhered, and a circular guard 18 is fitted in this groove 20 slidably. When a high frequency current flows to an induction heating coil 13, a line of magnetic force is produced, penetrates the top plate 11, and heats the bottom surface of a deep pan for cooking 21 placed on the top plate 11. At cooking, it may happen that the deep pan 21 is dislocated sideways or falls off from the body 10 resulting from application of an excessive force on the pan 21 by a trowel, etc., but such occurrence is prevented by supporting with the guard 18. Because the guard 18 is fitted between the top plate 11 and case 12 slidably, it is possible to move the direction where the grip of the pan exists any as desired. Accordingly a user in cooking is precluded from the risk of a burn caused by touching the side face of the pan 21 undeliberately.

IPC: B22F3/14
Filed: 1989-05-17
Abstract: PURPOSE:To improve cooling capacity by adding a nozzle having a throttle and an injection gas guide tube to a standard hot isostatic press(HIP). CONSTITUTION:In a HIP in which an inverted cuplike heat insulating layer 4 is disposed in a pressure vessel 2 sealed with high pressure gas, and a heater 5 and a material to be treated is contained in the layer 4, gas of a gas cylinder 11 is pressurized by a gas compressor 10, and arrived at a nozzle 9 via a through hole 17 passing a lower cover 3 of the vessel 2. The bore of the nozzle 9 is reduced, and gas is rapidly diffused from the nozzle 9. The gas diffused from the nozzle 9 is fed through an injection gas guide tube 7 to the top of the inner face of the layer 4, and then diffused in the furnace. Thus low temperature gas having high density is spread to the upper part in the furnace, and vigorous convection with high temperature gas in the furnace having low density is immediately caused. As a result, the convection heat transfer rate in the furnace is raised, the interior is satisfactorily mixed in the furnace, and the temperature in the furnace is made uniform.

Abstract: PURPOSE:To eliminate the noise contained in data by excluding both the maximum and minimum values of the input data and adding other remaining data together to obtain the average value. CONSTITUTION:1st comparison means 120 and 121 compare the values of two input signals with each other. Then the larger output values of those input signals are compared with each other by a 2nd comparison means 122. In the same way, a 3rd comparison means compares the smaller output values of both means 120 and 121 with each other. Then the maximum/minimum value extracting means 200 consisting of combinations of said 1st-3rd comparison means are provided in the number corresponding to the number of input data. The larger and smaller values of the outputs are compared with each other between two means 200 respectively. These comparing jobs are repeated and the larger one of two inputs is finally eliminated as the maximum value of the input signal by a maximum value extracting means 124. While a minimum value extracting means 125 eliminate the smaller one of two inputs as the minimum value of the input signal. Then other remaining output values are added together by an adding means 130. Thus the noise eliminating effect is secured.
