Title: Washing of metal base body
Inventor: SAMEJIMA TEIICHIRO
IPC: C25F1/04
Filed: 1990-11-28
Abstract: PURPOSE:To wash a metal base body stuck with a different metal soil in a corrosion inhibiting condition by dipping a treated base body and a pair of electrode in an electrolytic solution, connecting to a prescribed DC power source apparatus, and reversing the polarity of the apparatus at a point that a measured corrosion inhibition potential of the base body on a reference electrode is coincident with a set corrosion inhibition potential CONSTITUTION:In the electrolytic solution in such that a natural potential of the metal soil is equal to or smaller than the corrosion inhibition potential of the metal base body, the treated base body and the pair of electrodes of Pt, etc., are dipped and the positive terminal of the automatic constant potential DC power source being reversibly in polarity is connected to the base body and the negative terminal is connected to the pair electrodes. Until the corrosion inhibition potential of the base body measured with the reference electrode of a saturated calomel electrode, etc., provided in the vicinity of the base body is coincident with the corrosion inhibition potential being set on the power source of the base body, the soil only is dissolved and removed by flowing a DC current from the metal soil only. At the point that the measured corrosion inhibition potential is coincident with the set corrosion inhibition potential, the polarity of the power source is automatically reversed and the electric current being necessary to maintain the corrosion inhibition potential is flowed from the paired electrodes and the base body is perfectly protected from the corrosion.

Title: Steem type of electric cooking-vessel for thin slice of beef parboiled in hot soup
Inventor: FUAN SHIENTAI
IPC: A47J27/00
Filed: 1989-12-21
Abstract: PURPOSE: To make the distribution of the temperature of an action fluid uniform within the area of use in a pot, and to raise the temperature of the fluid, by equipping the middle part of the base of the pot with a steam generator that produces steam and heats the fluid by this particular steam. CONSTITUTION: This electric-steam pot for shabu-shabu (thinly sliced tender beef and various vegetables cooked at the table in boiling broth, usually served with a few kinds of dipping sauce) is composed of the lid 1 of the pot, the body 3 of the pot, the base 6 of the pot, and a steam generator 11. The steam generator 11 consists of a steam cover 2 and a heating unit 5. The lid 1, the steam cover 2, the body 3, and the base 6 are cast of sintered ceramics or metal. If an electric current is applied to the pot, the action fluid flowed from through holes 10 of the steam cover 2 to the steam generator 11 is heated at once by the heating unit 5, and if the temperature goes up to a certain extent, the fluid within the steam cover 2 is boiled and the upper part of this steam cover 2 is filled with steam.  By the pressure of this steam, the steam and the heated fluid within the steam cover 2 are spouted rapidly out to the exterior of the steam cover 2, i.e., to the area of use from the through holes 10. Consequently, the fluid of a relatively low temperature within the area of use can flow in from the through holes 10 to the steam cover 2. Thus, the convection of heat between the inside and the outside of the steam cover can be carried on.

Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To modify the low-temperature characteristics of the specific resistance of an electrotyte and a secular change of the electrolyte at a high temperature, by a method wherein a maleic acid salt is made to dissolve in a mixed solvent, which consists of a r-butyrolactone and an ethylene glycol containing the r-butyrolactone as its main solvent and containing the ethylene glycol as its subsolvent, and a 18-crown-6, which is shown by a specified formula, is added to the mixed solvent at a value in a specified range. SOLUTION: Maleic acid salt is made to dissolve in a mixed solvent, which consists of a r-butyrolactone and an ethylene glycol containing the r-butyrolactone as its main solvent and containing the ethylene glycol as its subsolvent, as a solute and 0.01 to 5.0 wt.% of a 18-crown-6, which is shown by the formula, is added to the mixed solvent. That is, the water in the mixed solvent produced at an ordinary ratio of ethylene glycol/water = 75/75 is substituted for the r-butyrolactone, the mixed solvent is set at a ratio of ethylen glycol/r-butyrolactone = 75/75 and moreover, the mixing ratio of the r-butyrolactone to the ethylene glycol is augmented in order. Therefore the more the amount of the r-butyrolactone is increased, the smaller the specific reistance value of an electrolyte at a low temperature is reduced.  Further by adding the 18-crown-6, which is shown by the formula, an increase in the specific resistance value of the electrolyte is suppressed.
