  • Patent number: 6459991
    Abstract: The present invention provides a collision in right/left turn prevention system which can automatically stop a vehicle even when a driver of the vehicle can not correctly grasp a course of a vehicle running in the counter direction because of the road line form or because the counter vehicle is hid behind other vehicles, or when a velocity of the counter vehicle is faster than that estimated by the driver.

  • Patent number: 6360171
    Abstract: A system-enabled vehicle entering a crossing warns a driver of the vehicle that a possibility of bumping exists, thereby allowing the driver to brake and stop the vehicle in an emergency in front of the crossing. When the system determines a possibility of bumping with another vehicle entering the crossing exists, the system continuously provides controls for decelerating and stopping the vehicle in a range from a point where the system can decelerate the vehicle in an emergency with time allowance for stopping the vehicle in front of the crossing up to a point in front of the crossing.

  • Patent number: 6337637
    Abstract: The collision with pedestrian prevention system according to the present invention comprises pedestrian detection means, road surface conditions detection means, road information accumulation means, vehicle position detection means, vehicle state detection means, processing means, information output means, and vehicle control means. Because of the configuration, the driver is alerted the presence of any pedestrian on a pedestrian's crossing and can immediately correct operations for handling the vehicle without being perplexed by the information just about to finish crossing the road. This system works only when there is the possibility of collision between a pedestrian on a pedestrian's crossing and a vehicle, and provides automatic controls for decelerating or stopping the vehicle when the driver can stop the vehicle by emergently braking over a distance from the vehicle to the pedestrian's crossing.

  • Patent number: 4886848
    Abstract: This invention discloses a flame retardant thermoplastic polyurethane resin composition containing a halogen flame retardant and a flame-retardant, water-resistant thin insulated wire prepared by applying the flame retardant thermoplastic polyurethane resin composition to a conductor to form an insulating layer having a thickness of 0.3 mm or less. The flame retardant thermoplastic polyurethane resin composition is prepared such that 0.2 to 20 parts by weight of a cycloparaffinic compound having an epoxy group is added to 100 parts by weight of a thermoplastic polyurethane resin alone or contained as a major constituent in a thermoplastic resin.

  • Patent number: 4814130
    Abstract: In a method of manufacturing an extruded product of a fire-retardant crosslinked polyolefin composition, including the steps of mixing 10 to 200 parts by weight of at least one material selected from the group consisting of an inorganic fire retardant, an organic fire retardant, and an inorganic filler to 100 parts by weight of polyolefin, adding predetermined amounts of an unsaturated alkoxysilane and a radical polymerization initiator to the resultant mixture to cause silicone grafting, and bringing a reacted mixture into contact with water in the presence of a silanol condensation catalyst, a cooling zone is formed between an extruder and a crosshead to set a uniform temperature of a molten resin composition and to cool the composition temperature to a desired temperature.
