Title: Manufacture of grooved substrate
Inventor: OONO SEIGO
IPC: G11B7/2533
Filed: 1982-08-24
Abstract: PURPOSE:To form accurately fine grooves on an optical disc substrate or the like in a short time, by using anacrylic polymer degradably by far-ultraviolet rays capable of forming required grooves by selective irradiation of the far- ultraviolet rays. CONSTITUTION:A substrate is made of a polymer degradable by far-ultraviolet rays such as polymethyl methacrylate, hexafluorobutyl methacrylate and grooves for an optical disc is formed by irradiating the far-ultraviolet rays on the substrate by contact exposure through a mask with fine pitches, or by scanning and exposing a laser beam of far-ultraviolet rays without the mask. A metal such as Te is vapor-deposited on the grooved side of the substrate to obtain the optical disc and the substrate for a master stamper. Since pitches and withds of the grooves can be controlled by the mask and the beam, and depths of the grooves can be controlled by the irradiation time and the light intensity, arbitrary grooves can be formed accurately in a short time.

IPC: G01S17/93
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To avoid the errors of determining an object as an approaching object, even if it is not while constituting a rear sensor at low cost. SOLUTION: A rear sensor 2 outputs a plurality of wave motions for detection from the rear of own vehicle toward different regions and captures the reflected waves, in response to each of the wave motions for detection. Through this, the location of a wave motion reflecting point in the rear of own vehicle is detected, and an object in the rear of own vehicle is discriminated by an object discriminating means 6, on the basis of the continuity of information on the location of a wave motion reflecting point. Then the relative speed of the object discriminated by the object discriminating means 6 with respect to own vehicle is computed by determining means 7 and 8. On the basis of the relative speed, it is determined whether or not the object is an approaching object.  At this time, a shape specifying means 6B specifies the shape of the object discriminated from the information on the location of a wave motion reflecting point by converting it into numerical form, and a change amount computing means 6C computes the amount of change in the numerical value indicating the specified shape in a predetermined time. At this time, determining means 7 and 8 either exclude the object with a predetermined amount or more of change in the numerical value indicating the shape from objects of the computation of relative speed or excludes the objects of the computation of approaching objects.
