Title: Failure determining device for air bag device
Inventor: MIZUI NOBUAKI
IPC: G01M17/007
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To correctly determine whether normally applied voltage and the voltage other than the normally voltage are applied or a normally supplied current and a current other than the normally current are supplied or not by applying voltage less than a designated value to a resistance or supplying a current less than a designated value. SOLUTION: Failure determination determines whether a short failure of short-circuiting in a connecting wire between a power supply wire and a scribe resistance Req occurs or not. If the output voltage V2 of an operation amplifier 16 is larger than a threshold, the squib resistance Req is in the disconnecting state so that a failure is not determined. If the output voltage V2 of the operation amplifier is less than the threshold, it is judged whether a failure of applying voltage other than the normally applied voltage is caused or not. That is, the squib resistance Rsq is not in the disconnecting state, so that the monitor voltage V1 is taken, and it is judged whether the monitor voltage V1 is larger than the threshold or not. Thus, it is determined whether the voltage other than the normally applied voltage is applied to the squib resistance Rsq or not.

Title: Magnetic recording tape
Inventor: TOMITA HIROSHI
IPC: B29C55/12
Filed: 1985-10-29
Abstract: PURPOSE:To make the titled tape resistant to variations in the tension due to a sudden start and a sudden stop by providing a magnetic layer on one surface of a biaxially oriented polyethylene-2,6-naphthalene dicarboxylate having specified F-5 value in the longitudinal direction, refractive index in the thickness direction, intrinsic viscosity, and air leakage index. CONSTITUTION:The magnetic layer is provided on the surface of a biaxially oriented polyethylene-2,6-naphthalene dicarboxylate having >=20kg/mm<2> F-5 value (stress manifested in 5% elongation), >=1.490 refractive index Nz in the thickness direction, >=0.50 intrinsic viscosity, and <=1,000sec air leakage index to obtain the magnetic recording tape. When the F-5 value in the longitudinal direction is less than the value, strain remains when instantaneous high tension is exerted, the film can not be thinned, and eventually the recording density per unit volume can not be enhanced. When the refractive index Nz in the thickness direction and the intrinsic viscosity are beyond the limits, the end face of the slit tape becomes a so-called high edge, the appearance of the roll when the tape is rolled up on a reel is worsened, and the collapse of the roll can be caused.
