Abstract: PURPOSE:To evaluate a rubbed orientated film properly by arranging a polarized light irradiation means, a transmitted light detection means and an orientated film evaluating means. CONSTITUTION:Infrared rays L which are polarized parallel to a plane defined by a direction B of rubbing an orientated film sample 7 and the normal to the surface of the sample are directed to the sample 7 at various angles (-90<=theta<=+90) from the normal of the sample surface, and passed through the sample 7, and an absorbance or a difference between absorbances at angles +theta and -theta of incidence is measured. In the measurement, the sample 7 is fixed on a jig 20 with a fixed angle of inclination and after the measurement of an infrared absorbance, the sample 7 alone is turned by 180 deg. to measure the infrared absorbance with the angle of the jig 20 remaining unchanged to the infrared rays L. By this method, the measurement is made with the angle of the sample 7 to an infrared rays path set at + or - (fixed angle). The measurement may be made in FT-IR to use the absorbance at a specified absorption wavelength of a high polymer in a spectrum obtained.

Title: Sliding friction force measuring apparatus
Inventor: SOGA SHIGETOSHI
IPC: G01M17/02
Filed: 1991-12-25
Abstract: PURPOSE:To always enable the measuring of a friction force regardless of irregularities of the surface of a road by providing horizontal load detectors at two points above and below a support member for supporting a measuring wheel to determine a difference of both detection loads. CONSTITUTION:When a driving force (braking force) is applied gradually with a drive brake while a measuring wheel 1 runs to the right contacting the surface G of a road, a friction force F is generated on a contact surface between the wheel 1 and the road surface G. The force F increases in proportion to the magnitude of the driving force (braking force). But when the force exceeds the maximum friction force determined by a friction coefficient between the road surface G and the wheel 1, the wheel 1 comes to contact the ground slipping and a sliding friction force smaller than the maximum friction force works. The friction forces are detected with horizontal load detectors 24 and 24a (load value Fta detected by both the detectors) and 32a (detection load value Fta) provided at two points, upper and lower, as force working on an air cylinder 12 through support devices 7 and 10, a piston rod 11 and the like. The force F is determined by computing F=-(Fta+Ftb).
