IPC: C07C67/00
Filed: 1983-08-26
Abstract: PURPOSE:To obtain the titled compound useful as a flame-retardant for paper in good heat stability in high purity in high yield without producing by-products, by reacting ammonium sulfamate with dicyandiamide under specific pressure in a molten state. CONSTITUTION:Ammonium sulfamate is reacted with dicyandiamide undrr pressure of 20-0.01kg/cm<2>G under heating (e.g., 140-170 deg.C, or 170-190 deg.C) in a molten state, to give sulfamic acid guanidine.

Title: Hardening method of resist film
Inventor: MORI HIROFUMI
IPC: C08J7/14
Filed: 1979-11-30
Abstract: PURPOSE:To enhance water resistance in etching without using chromic acid anhydride, by reacting maleic anhydride with a photo-crosslinked polyvinyl alcohol (PVA) film in 2 steps with heating in order to harden it. CONSTITUTION:A resist film prepared by photo-crosslinking a water soluble resist film of a combination of a PVA resin and a photosensitive agent is immersed in 50% maleic anhydride solution (a solution of a solvent, such as acetone or acetic ester not dissolving the resist film) at >=50 deg.C for several minutes-several tens minutes to form a half maleate. Subsequent heating at 150-250 deg.C for about 5- 30min cross-links and hardens the resist film, which is not swollen or flaked by an aqueous etching solution in the next etching step, thus permitting precise etching processing of a metal layer under the resist layer to be effected.

Abstract: PURPOSE:To perform a positive sensing of occurrence of abnormal state and perform a safe cooking operation by a method wherein in the case that a variation rate of temperature within a heating chamber in respect to time is lower than its predetermined value, this is judged as an abnormal temperature so as to stop a heating and cooking operation. CONSTITUTION:A resistance heat generating source 105 is driven to heat a food in a heating chamber with hot air, and a temperature sensing means 101 detects a temperature within the heating chamber. A calculation means 102 receives an output from a temperature sensing means 101 and calculates a rate of variation of temperature in the heating chamber in respect to time. A comparing means 103 compares the rate of variation in respect to time with a predetermined value, and a control means 104 judges it abnormal if its variation rate in respect to time is lower than a predetermined value, and stops the heating means 105. That is, in the case that the rate of variation in respect to time does not reach the predetermined value after driving the resistance heating source 105, the control means judges it abnormal and stops the heating means 015, so that even in the case that a blower fan in a hot air blowing type oven is troubled, its abnormal state can be positively detected and the heating operation is stopped, resulting in that a safe cooking operation can be performed.
