Abstract: PURPOSE:To easily adjust electric power supplied to a heat generating layer and to facilitate control by allowing plural electric feeding members which are divided to different length in a circumferential direction to slide on both ends of plural resistance heat generating elements which are divided in a circumferential direction and extend axially. CONSTITUTION:A heat generating layer 3 provided to a cylindrical base material 5 consists of plural resistance heat generating elements 31, 32... and exposed contacting parts 31A, 32A... are formed at both end parts.

Title: Production of propylene glycol monooleate
Inventor: KUBO YOSHIFUMI
IPC: C07C67/24
Filed: 1985-12-11
Abstract: PURPOSE:To obtain the titled substance, by producing a sufficiently purified oleic acid from an organic solvent solution of urea and a fatty acid mixture containing oleic acid and adding propylene oxide to the oleic acid using a tertiary amine or quaternary ammonium salt as a catalyst. CONSTITUTION:Urea and a fatty acid mixture containing oleic acid are dissolved in an organic solvent (e.g. methanol) and the solution is cooled to remove >=16C higher saturated fatty acids and higher mono-unsaturated fatty acids having larger carbon number than oleic acid from the solution as a urea adduct crystal. The residual organic solvent solution is partially saponified with a base to form an acidic salt of oleic acid. Since the salt forms an easily filterable crystal by forming an adduct with a small amount of residual urea, the removal of impurities can be carried out in high efficiency and a high-purity oleic acid can be produced. The titled colorless and odorless substance having high stability can be produced by adding propylene oxide to the high-purity oleic acid using a tertiary amine or a quaternary ammonium salt as a catalyst. USE:Emulsifier for foods and pharmaceuticals.
