Title: Magnetic recording medium and its production
Inventor: INOUE ISAMU
IPC: G11B5/72
Filed: 1989-05-11
Abstract: PURPOSE:To obtain a medium having excellent contact durability against a magnetic head and to reduce spacing loss between a magnetic layer and a magnetic head by forming the magnetic layer of a ferromagnetic thin film essentially comprising ferromagnetic material and graphite dispersed therein on a substrate. CONSTITUTION:The magnetic layer 2 formed on the substrate 1 is a ferromagnetic thin film 3 essentially comprising ferromagnetic material with graphite 4 dispersed therein. Since graphite 4 has lubrication property by itself, the magnetic layer thus formed has a low coefft. of friction against a magnetic head and excellent wear resistance even when the layer 2 is not covered with a lubricating protective film. Thereby, the medium has enough durability and recording/reproducing can be performed by directly bring a magnetic head into contact with the magnetic layer. The obtd. medium can be used for high- density recording with little spacing loss.

Title: Valve-timing controller for internal combustion engine
Inventor: HASHIMOTO TAKESHI
IPC: F01L1/34
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of exhaust gas caused by the continuation of a controllability impairing state by operating the controlled variable, on the basis of a learned value as the most retarded standard. SOLUTION: An actual valve timing detecting means 203 detects on actual valve timing Ta of at least one of an intake valve 17 and an exhaust valve 18. An actual valve timing control means 204 produces a controlled valiable to VVT 40 to make deviation between the target valve timing Ta and the actual valve timing To zero. The controlled variable is corrected and operated with a learned value LRN as the most retarded standard. The VVT 40 is driven by OCV 80 to change the opening and closing timing of at least one of the intake valve 17 and the exhaust valve 18. A learning means 206 incorporates the actual valve timing Ta in the operation of an engine 1 and calculates the lowest retard valve timing as the learned value LRN to be used in the calculation of the actual valve timing Ta.
