Title: Manufacture of aluminum extrusion member
Inventor: MOCHIZUKI ATSUO
IPC: C23C14/06
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To make a die durable for a long usage without mending by forming an abrasion resistant membrane of a DLC film to a bearing face formed on the mold after it is polished and finished like a mirror. SOLUTION: After forming a bearing face on an aluminum extrusion die by a normal method such as a cutting processing, an electroerosion processing and the like, a mirror-like finishing is applied to the bearing face. Thereafter, a DLC film is coated to the bearing face as an abrasion resistance membrane. DLC is a carbon film having a character resembling to a diamond and is publicly known for itself. An abrasion resistant membrane coating is carried out by a PVD method (physical vacuum evaporation method). The aluminum extrusion die is divided so as to be easier for coating the bearing face, and the DLC film is formed on the divided bearing face. An aluminum extrusion member is manufactured by an extrusion molding, using the aluminum extrusion metal thus formed. Forming of die mark is thus reduced, and the aluminum member of high surface quality can be obtained.

IPC: F02D41/14
Filed: 1988-07-15
Abstract: PURPOSE:To improve the responsiveness of an air-fuel ratio correction control by changing an air-fuel ratio controlled variable by a defined quantity to the side of bringing an actual air-fuel ratio close to a target air-fuel ratio at the time of detecting reverse change of the changing quantity of the output signal of an oxygen density sensor. CONSTITUTION:As a signal corresponding to the air-fuel ratio of a mixture fed to an engine 1 is outputted from an oxygen density sensor 15, an electronic control circuit 21 obtains the deviation in air-fuel ratio between a target air-fuel ratio and an actual air-fuel ratio. Then, an air-fuel ratio controlled variable is set in line with the deviation in air-fuel ratio. When it is detected that the changing quantity of the output signal of the oxygen density sensor 15 is reversely changed from positive to negative or vise versa, the air-fuel ratio controlled variable is changed by a defined quantity to the side of bringing an actual air-fuel ratio close to a target air-fuel ratio. By controlling the air-fuel ratio of the mixture fed to the engine 1 based on this air-fuel ratio controlled variable, the gas delay time from when fuel is fed and burned until oxygen density is detected by the oxygen density sensor 15 can be sufficiently compensated.

CONSTITUTION:A soundproofing material is consists of a dense surface layer 1, the first sound absorbing layer 2 composed of a perforated material, a dense sound insulating layer 3 and the second sound absorbing layer 4 composed of the perforated material and is mounted to a dashpanel 5 before use. By this means, two resonance systems are constituted and the peak of resonance frequency is transferred to a high frequency region and the lowering of a sound absorbing rate in the high frequency region is reduced. Further, sound insulating properties are enhanced as frequency becomes high. The sound absorbing rate shows a high value when the first sound absorbing layer 2 is thicker than the second sound absorbing layer 4 and transmission loss is enhanced when the second sound absorbing layer 4 is thicker than the first sound absorbing layer 2. The sound absorbing rate is enhanced in a low frequency region as the surface density of the sound insulating layer 3 is high and also enhanced in a high frequency region as the surface density is low and transmission loss is enhanced as the surface density of the sound insulating layer 3 is high. When the thicknesses of the first and second sound absorbing layers 2, 4 are made almost equal, the sound absorbing rate and transmission loss show adequate characteristics as a soundproofing material.
