Title: Simultaneous biaxial orientation of plastic film
Inventor: ASAKURA MASAYOSHI
IPC: B29C35/02
Filed: 1986-08-06
Abstract: PURPOSE:To prevent the generation of the breakage of a film, by a method wherein the orientation of the film is effected while maintaining the temperature of at least the film gripping unit of a clip within a specified range. CONSTITUTION:In a method wherein both ends of a plastic film is gripped by clips to orient the film into biaxial directions simultaneously, the orientation is effected while maintaining the temperature of the film grip units of clips within the range of 60-130 deg.C. The draw ratio of the simultaneous biaxial orientation of an unoriented film, which is effected in order to improve the strength characteristics of the film and reduce an unevenness in the thickness of the film, is preferable to be 2.5-6.0 times in both of longitudinal and transversal directions. When the simultaneous biaxial orientation of an oriented film is effected it is preferable to apply it on the biaxial orientation of the film, oriented transversally and longitudinally whose refractive index in a plane including the longitudinal and transversal directions of the film is 1.590-1.640. The draw ratio of the simultaneous orientation is preferable to be within the range of 1.3-2.0 times in both of the longitudinal and transversal directions. When the temperature of the film gripping unit is up to 60 deg.C, the orientating property of the film at a part, gripped by the clip, is not improved and the film is readily broken, however, when it exceeds 130 deg.C, the film is crystallized, therefore, the film is readily broken.

Abstract: PURPOSE:To prevent fire or the like from occurring by a method wherein when a frame rod is short circuited, a burner is forcedly ignited for a specified period of time, a hot air temperature under the forced combustion at the burner and a temperature of atmosphere before combustion are compared from each other, the ignition at the burner is confirmed and in the case that the burner is not yet ignited, a fuel injection amount is restricted. CONSTITUTION:A frame rod voltage is measured before starting a forced combustion, and if the frame rod voltage is 1.0V or more, for example, it is discriminated that the frame rod is short circuited with a leakage current. In the case that the short circuited state of the frame rod is detected, each of the combustion driving devices such as a solenoid pump 2, a burner fan 3, an ignition transformer 6 and a proportional control nozzle 8 is operated unconditionally to ignite the burner. At this time, just after starting of the forced combustion (after about 10 seconds), a hot air temperature just after starting the forced combustion is measured by a hot air temperature sensor 10 this temperature and a temperature of atmosphere before starting the forced combustion are compared to each other, and if the temperature difference is confirmed to have more than a specified increased temperature, it is confirmed that the burner is ignited.
