Title: Water-proof sheet
Inventor: TAKASHIMA SEIZO
IPC: B32B25/08
Filed: 1987-12-08
Abstract: PURPOSE:To obtain a water-proof sheet which is free from partial relief even during the use at high temperatures, by providing a foaming sheet layer at one surface of a vulcanized rubber sheet having weather resisting property, which sheet layer contains continuous cells and is provided with net-patterned grooves therein. CONSTITUTION:There is formed a foaming sheet layer 2 at one surface of a vulcanized rubber sheet 1 having resistance against the weather. The foaming sheet layer 2 contains continuous cells, and moreover it is provided with net-patterned grooves 3. The foaming sheet layer 2 at the lower side and adhered to a foundation may be formed of vulcanized rubber foaming material having resistance against the weather or a high-molecular foaming material. In this case, it is particularly desirable to use the same rubber as that of the vulcanized rubber sheet at the upper side from the viewpoints of the manufacturing process and strength. In other words, when the water- proof layer 1 and the foaming sheet layer 2 are made of the same material, it is convenient in that the water-proof layer 1 and the lower sheet 2 containing the foaming agent can be laminated while they are raw, and then moved into the vulcanizing process where they are integrally vulcanized and molded. The grooves 3 in the foaming sheet layer 2 which are in the form of a lattice, honeycomb or rhombus, etc. are continuously communicated to each other.

Title: Digital interface recording method
Inventor: ITO MASATOSHI
IPC: G11B20/10
Filed: 1988-12-08
Abstract: PURPOSE:To cut a defective recording part in which no recording synchronism is taken by rewinding a tape to a position where recording servo is locked normally before an unlocked state is detected. CONSTITUTION:A system controller SCON 5 monitors the locked state of the recording servo by a detecting signal inputted from an unlock detecting part 4b while performing digital interface recording, and measures the duration of the unlocked state when it is generated. When the unlocked state continues exceeding prescribed time, the tape is rewound to the position where the recording servo is normally locked before the unlocked state is detected by a feed control part 6. After that, the SCON 5 performs record pause at a rewound appropriate locked position, and starts recording after the unlocked state is recovered to a normal locked state.

Title: Rolling bearing
Inventor: HAYASHIDA KAZUNORI
IPC: F16C33/62
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To attain extending of a life by improving lubricating ability and wearing resistance on a surface of a raceway ring and a rolling element, in a rolling bearing. SOLUTION: In a rolling bearing A using a fluorocarbon lubricant, a diamond like carbon film 5 is formed in at least any of a raceway surfaces of inner/outer rings 1, 2 or a surface of a rolling element 3. Since the fluorocarbon lubricant has good wettability relating to the diamond like carbon film 5, an oil film of the fluorocarbon lubricant is difficult to be interrupted even when the rolling element 3 is slid without rolling. Even when the oil film is temporarily interrupted, by protecting a rolling/sliding location with the diamond like carbon film 5 of very hard quality, direct contact between the inner/outer rings 1, 2 and the rolling element 3 is avoided.
