摘要:
A substantially rectangular insulating substrate is prepared. Next, pairs of lead electrodes are formed on the substrate such that they extend in parallel with regular intervals and slantwise with reference to the longitudinal direction of the substrate. The electrodes are formed by use of a lithography technology, including deposition and etching. Then, a resistor material is pasted on the substrate and the electrodes by screen printing, to thereby form a strip-shaped resistor extending in the longitudinal direction. Finally, a protective layer is formed on the resultant structure, so as to prevent the resistor and the electrodes from being oxidized or worn away, thereby completing the fabrication of a thermal head. In this thermal head, each of those portions of the strip-shaped resistor which are defined by a pair of adjacent lead electrodes serves as a parallelogrammatic heating resistor used for recording one pixel.
摘要:
Oleaginous material is fractionated into two fractions having different melting points from each other by emulsifying all the oleaginous material with water and using with a surfactant having an HLB value of 5 to 10 as an emulsifier, at a temperature at which all the oleaginous material is substantially melted. The emulsion is cooled to a temperature at which one fraction of the oleaginous material crystallizes so that the emulsion forms a lighter phase containing the other fraction of the oleaginous material and a heavier phase comprising an aqueous phase containing crystals of said first fraction dispersed therein. The lighter phase is separated from the heavier phase and then the crystals of the first fraction are separated from the remainder of the heavier phase.

A mixed acid triglyceride inhibits a hard butter from fat-blooming, having as the main acid moiety 15 to 70 wt. % of saturated fatty acids having 20 to 24 carbon atoms and 20 to 60 wt. % of unsaturated fatty acids having 16 to 22 carbon atoms.
摘要:
A gas sensor has a ceramic substrate carrying a first ceramic layer formed thereon and a second ceramic layer formed on the first layer, the two layers having successive setbacks from one edge of the substrate so as to form a staircase-like edge structure, and a gas-sensitive layer is formed on the staircase-like edge portion of said substrate, height of said gas-sensitive layer above the substrate being less than the thickness of the first ceramic layer.

Frozen desserts are prepared using, as an emulsifier, esters of elaidic acid with polyhydric alcohols selected from the group consisting of glycerol, propylene glycol, sorbitol and saccharose.
