Title: Ripper for large-depth excavation
Inventor: MATSUMOTO NORIHISA
IPC: E02F5/32
Filed: 1993-10-06
Abstract: PURPOSE:To facilitate excavation in large depth by holding a long shank for depth excavation to a shank holder in a vertically slidable manner and lifting and lowering the long shank by a cylinder for adjusting the length of the shank. CONSTITUTION:When a lift cylinder 11 is elongated, a shank holder 1 is displaced in parallel because a four-articulated link is formed by a link 9, a car- body rear section 8, a tilt cylinder 10 and the holder 1, and the edge of a long shank 2 is lowered as shown in the arrow. When the cylinder 10 is expanded and contracted, the front end of the shank 2 is rotated before and behind. The front end of the shank 2 penetrated into the hole of the holder 1 in a freely vertically slidable manner is lifted when the cylinder 3 is extended, and brought down when the cylinder 3 is shrunk. When the length of the shank 2 is adjusted completely, a lock mechanism consisting of a holding cylinder, etc., is operated, and the falling of the shank 2 is prevented while thrusting-up external force during operation is relieved and the length of the shank 2 is kept constant. Accordingly, excavation depth during travelling can be changed freely, and can be maintained.

Abstract: PROBLEM TO BE SOLVED: To enable an optical device to be used in a vacuum ultraviolet region of <=200 nm wavelength. SOLUTION: A fluorite (CaF2) with 2 inches diameter and 2 mm thickness is used for a substrate 11. A calcium fluoride (CaF2) film 12 with 0.434 μm film thickness is deposited on the substrate 11 with a resistance heating vacuum deposition device (a).

The ECU 76 judges whether it is within a torque limit or not to perform a steering assist torque control, and in case of NO, it judges that the steering assist torque control of lane holding is improper and performs a steering or torque control. When an abnormality is detected in a torque sensor output, harness, or CPU, drive of an electric motor 38 is stopped to stop the current-carrying to a FET switching element. Thus, an abnormality of signal can be detected or judged while preventing the lane deviation of a vehicle, and a proper countermeasure can be taken thereto.
