    摘要： A retarder for gypsum plaster is provided which consists essentially of .beta.-hydroxy-.beta.-carboxy-isocaproic acid or a water soluble salt thereof. It has powerful retarding effect toward gypsum plaster and gives a solid product having much better mechanical strength than that encountered when an alkali metal salt of citric acid or powdered glue which are the ordinary set retarders are used. A process for retarding the setting of gypsum plaster by the use thereof, is also provided.

    摘要： A collision avoidance apparatus capable of executing an appropriate vehicle control in order to avoid a collision between an own vehicle and a movable object is provided. A collision avoidance apparatus for avoiding a collision between an own vehicle and a movable object includes: a laterally-existing movable object detector for detecting for a movable object that approaches from a direction lateral to the own vehicle; a side collision determination section for determining whether or not a risk that the own vehicle and the movable object collide with each other is high, when the laterally-existing movable object detector has detected the movable object that approaches from the direction lateral to the own vehicle; a passage and avoidance determination section for determining, when the risk that the own vehicle and the movable object collide with each other is determined to be high, whether or not a possibility that a collision between the own vehicle and the movable object can be avoided by the own vehicle passing in front of the movable object, is high; and an accelerated state/decelerated state controller for controlling the own vehicle to be in one of an accelerated state and a decelerated state, according to a determination result of the passage and avoidance determination section.

    摘要： An antenna cover (1) for a radar (2) for a vehicle has a rectangular parallelepiped shape, having a flat cover top (10) that faces a microstrip antenna (21a, 21b) of the radar (2) and a sidewall (11) that covers the microstrip antenna (21a, 21b) sideways. The sidewall (11) is located out of the range where the electromagnetic waves to be received by the microstrip antenna (21a, 21b) are directly received. An inner face (11a) of the sidewall (11) is at a right angle to the cover top (10). An outer face (11b) of the sidewall (11) is at a constant angle θ larger than 0 degree but smaller than 90 degrees, to the inner face (11a) of the sidewall (11). The sidewall (11) is structured such that its thickness increases toward the side where the microstrip antenna (21a, 21b) is present.
