Inventor: SHINDO MASAHIRO
IPC: B60G17/00
Filed: 1994-03-07
Abstract: PURPOSE:To provide a detector for measuring a wide range of acceleration so that an external impact on a vehicle can be detected. CONSTITUTION:An emergency state detecting section 22 of drive recorder comprises a selector 46, an amplifier 42 with a high amplification factor, and an amplifier 44 with a low amplification factor. The selector is connected with an acceleration sensor 40 of a vehicle. The acceleration detected by the acceleration sensor 40 is amplified by the amplifier 42 and converted by an A/D converter 48 into a signal and outputted to a signal judging section 50. When a signal from the A/D converter 48 exceeds a specified threshold, the signal judging section outputs a switching signal to the selector 46 to select the amplifier 44 so that the acceleration signal from the A/D converter 48 may be limited within a fixed range. When the amplifier 44 is selected and the acceleration signal from the A/D converter 48 still exceeds a specified value, a judging section 52 makes a judgment that the vehicle receives an impact and eventually comes into an emergency.

Abstract: PROBLEM TO BE SOLVED: To obtain a coated tool minimal in the weal of a coating film by forming a wear resistant film containing specific percentages of Ti, Al, V, C, N, and O on a base material and regulating the thickness of the film to a specific range. SOLUTION: The coating film has a composition represented by (Tix , Aly , Vz ) (Cu , Nv , Ow ), where the symbols (x), (y), (z), (u), (v), and (w) represent respective atomic proportions of the constituent elements and relationships, represented by x+y+z=1, u+v+w=1, 0.2<x<1, 0<=y<0.8, 0.02<=z<0.6, 0<=u<0.7, 0.3<v<=1, and 0<=w<0.5, hold among them. The thickness of the film is regulated to 0.5-15μm. Because this film is composed of Ti type ceramics, hardness is increased. Further, this film reacts with the components of a material to be machined and the oxygen in the air to form a low-melting oxide. Because this oxide acts as a lubricating film, the wear of the wear resistant film can be reduced and the wear loss of the film can be reduced.
