Abstract: The cooker comprises a boiling detective means (31) having judged the cooking to be in boiled state, and a time-controlling means (32) altering the heating at an M burner (13) to a weaker heating power than before the boiling. If, after the actuation of the time-controlling means (32), a detected temperature (Th) falls to show Th>TH-5 deg.C (given that the detected temperature at the time of the judgment of the boiling is an equilibrium temperature (TH)), a temperature- controlling means (34) keeps a temperature-controlling solenoid valve (133) open and keeps the combustion at the M burner (13) large until Th>=TH. If the detected temperature (Th) rises to show Th>=TH+10 deg.C, the temperature-controlling solenoid valve (133) is closed and the combustion at the M burner (13) is kept small until Th<TH+8 deg.C. The method enables efficiently cooking food in a manner of boiling it with addition of ingredients.

Title: Working method of concrete piles cast in position
Inventor: SHIN HONG-SIK
IPC: E02D5/38
Filed: 1993-05-20
Granted: 1996-10-09
Abstract: The method constructs the concrete piles by casting concrete into a casing with a shoe while driving the casing into a ground by use of striking force. The casing of a high strength is withdrawn to be repeatedly used in constructing other concrete piles. The method comprises the steps of : ramming the shoe(1) in a set position; arranging a concrete supplying vehicle to align the centers of the shoe(1) and a casing hole(6); inserting a steel net(7) into the casing(2), erecting the casing(2) and laying the lower part of casing(2) on a projection(4) by inserting the casing into the hole(6); measuring the vertical degree; supplying the concrete for the vehicle(3); striking the casing(2).

Title: Method for manufacturing polyamide
Inventor: HONG KI-HUN
IPC: C08G69/36
Filed: 1993-05-21
Granted: 1997-03-05
Abstract: The method provides polyamide resin having good color, molding property and release property in injection molding. Polyamide resin is prepared by polymerizing a polymerizable monomer with a polymerizable slurry containing polymerizable monomer, solvent for polymeriztion, release agent and alcohols. Release agent in the polymerizable slurry is added in amount of 0.1-1.0 wt.% based on polyamide polymer. In this case, if the content of release agent is less than 0.1 wt.% in polyamide polymer, the polyamide resin has not improvement effect of release property, if the content of release agent is at least 1.0 wt.%, the polyamide resin has little improvement effect of release property along an increase of addition amount as well as the release agent prevents monomer from polymerizing. Stearic acid-based release agents are used. And alcohols are added in amount of 0.1-3.0 wt.% based on polyamide polymer.
