IPC: B60T8/46
Filed: 1994-04-27
Abstract: PURPOSE:To provide a low-priced ABS system with a simple structure which can prevent ice and snow from adhering completely regardless of the structure of a vehicle. CONSTITUTION:When a brake switch 39 mounted on a brake valve 3 is changed from ON to OFF, an ice and snow adhesion preventing means 7a in an ABSECU 7 turns on a solenoid 27c in a solenoid valve for exhaust of respective modulators 9 for a preset time. As a result, when a brake is changed from its opening condition to its operation releasing condition, compressed air supplied to respective brake actuators is exhausted from the exhaust port of the respective modulators 9. It is thus possible to prevent ice and snow from adhering by exhausting compressed air from the exhaust port each time brake operation is released, and blowing off ice and snow adhering to the exhaust port.

IPC: H01L21/3205
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain a low-electric-resistance wiring layer having a high thermal stability, high stress-migration resistance and no defect such as hillock by providing a multi-layer wiring composed of layers having substantially same components where the grain size of each layer is nearly equal to its thickness. SOLUTION: A wiring layer 50 is composed of layers 52, 54, 56 having substantially the same compsn. on a substrate 17. The size d of the crystal grains 60 is pref. nearly equal to the thickness h of each layer 52, 54, 56 or has a relation of 0.5<d/h<2. Such structure is a laminate of brick blocks. The crystal grain size is nearly equal, this facilitating relaxing the compression stress due to the linear expansion coefficient difference between the layer 50 and substrate 17. If the grain size distribution is uniform, the possibility of the stress concentration lowers. If it is dispersed, the mechanism accelerates production of hillocks.
