Title: Method of discerning slope
Inventor: MAKABE MITSURU
IPC: G01P15/00
Filed: 1991-03-22
Abstract: PURPOSE:To correctly and easily discern a slope from output signals and the wheel speed by one G sensor. CONSTITUTION:The changing amount of the vehicle speed per unit time at the lowest wheel speed and the changing amount of the vehicle speed per unit time obtained by integrating the acceleration/deceleration of a weight-type G sensor 2 mounted in the back-and-forth direction of a vehicle body are obtained. It becomes possible to reliably distinguish an uphill slope and a downhill slope from the special relationship between the two kinds of the changing amount of the vehicle speed at the slope by utilizing the structural change of outputs of the G sensor at the slope.

Title: Polarization compensating device
Inventor: KOMATSU YOSHIROU
IPC: G02B27/28
Filed: 1983-05-13
Abstract: PURPOSE:To perform polarization compensation which is stable to the polarization state of single-mode fiber projection light by splitting incident light into two orthogonal linear polarized components, and rotating only one component and then multiplexing both components after passing them through optical paths differing in length. CONSTITUTION:A light wave projected from a single-mode fiber 1 is split into two mutually orthogonal linear polarized components by birefringent crystal 3, and they are coupled with polarization maintaining fibers 4 and 5 respectively. The polarization maintaining fibers 4 and 5 has some difference in fiber length so that two light waves do not interfere with each other when multiplexed by a light guide type Y-shaped multiplexer 6 while only one linear polarized component is rotated by 90 deg.. In this case, axes of polarization are so adjusted that both components propagating in the polarization maintaining fibers 4 and 5 are multiplexed efficiently on the incidence light guide 7 of the light guide type Y- shaped multiplexer 6.

Title: Measuring method for convex surface
Inventor: FUKUDA MITSUHISA
IPC: G01B11/24
Filed: 1980-06-20
Abstract: PURPOSE:To enable the measurement of a profile of a convex surface from a distance and an angle relation at each part, by a method wherein an incident direction and a reflection of a laser beam, which a surface to be measured reflects via a half mirror, coincide with each other through the adjustment of the angle of the half mirror.

The incident direction and the reflection direction of the laser beam are caused to coincide with each other through the rocking of the half mirror around a Z axis. In case, for example, a surface 1A to be measured reflects a laser beam LB, emitted from a light source 2, through a half mirror 3, the incident direction and the reflection direction are made to coincide with each other through the rocking of the half mirror around the Z axis, and this permits the decision of a cordinate of a reflection point P on the surface to be measured in a way to measure the angle theta of a line o q with the X axis and a rocking angle alpha of the half mirror by means of a goniometer and to measure a distance p q.
