Title: Rolling bearing
Inventor: TANAKA KENJI
IPC: F16C33/76
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent infiltration of foreign matter into a bearing while canceling air pressure difference between the inside and outside of a bearing by providing an opening/closing valve in a ventilation hole provided in a seal material over a ring for sealing a rolling body arranged between an outer ring and an inner ring. SOLUTION: A ventilation port 17, provided in a sealing material 15 for sealing a rolling body 44 arranged between an outer ring 41 and an inner ring 42, is provided with a thin opening/closing valve 18 for closing the ventilation port 17. This valve 18 is formed at a bearing outside 10B in the sealing material 15. With this structure, the ventilation port 17 is closed by the valve 18 in the normal condition to prevent the infiltration of foreign matter into an inside 10A of the bearing from an outside 10B of the bearing. Furthermore, when the difference of air pressure occurs between the inside 10A and the outside 10B of the bearing, the valve 18 is made curved and deformed so as to open the ventilation port 17 to canel the air pressure difference.

Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To provide remote control manipulation equipment and a remote control repeater with which remote control is surely enabled by a remote control transmitter even at the place where there are a lot of people or the remote manipulation equipment is located away. SOLUTION: When there are plural pieces of remote control manipulation equipment 21, 22 and 23 for which operations are controlled by remote control transmitters 24, 25 and 26, these plural pieces of equipment are connected through a remote control signal transmission line. When an inputted infrared remote control signal is not addressed to the equipment itself, each piece of equipment transmits that signal through the remote control signal transmission line to the other equipment. When, this signal is addressed to the other equipment itself, that equipment processes the operation similarly to the case of directly receiving the infrared remote control signal but when this signal is not addressed to the equipment itself, that signal is further transmitted to the other equipment.  Thus, since the plural pieces of remote control manipulation equipment 21-23 mutually receive and exchange the signals of the other pieces of equipment, it is enough for the user only to send the signal to the equipment on the best conditions, the operation is simplified and the exchange of the remote control signal is made sure.

Title: Pressure releasing device for oil-immersed electric appliance
Inventor: NAITOU TAKEHIKO
IPC: H01F27/40
Filed: 1979-03-22
Abstract: PURPOSE:To effectively suppress oil ejection without hindering gas release, by providing an oil ejection suppressor between the tank of an oil-immersed electric appliance and a pressure release cylinder. CONSTITUTION: A zigzag release passage 13 is defined by two concentric partition plates 11, 12 in the hollow box of an oil ejection suppressor 8 so that the release passage is bent upward and downward alternately. An oil reservoir 15 and an oil return hole 16 for connecting the reservoir to a tank 1 are provided on the halfway part of the zigzag release passage 13. The oil ejection suppressor 8 is mounted on the top lid of the tank so that the inlet port of the gas release passage 13 communicates with the opening 7 of the tank. The outlet port of the release passage 13 is connected to the gas inlet part of a pressure release cylinder 2 through flanges 17. When an accident occurs, a large amount of produced gas blows up together with insulating oil 6 to an upper space 18, flows into the release passage 13 of the suppressor 8 through the opening 7 and collides against a ceiling 9 so that the energy of the gas and the oil is reduced and a portion of the blown- up oil returns into the tank 1. The other portion of the oil loses its energy while proceeding in the releasepassage 13 so the the portion stays in the oil reservoir 15. The gas of small specific gravity goes through the release passage without undergoing resistance so that the gas reaches the outlet port of the release passage.
