The present invention provides a wiring board giving good heat dissipation over a long period of use. The present invention also provides a method for producing a wiring board, including coating a surface of a metal substrate, which is made of an aluminum plate, with a composition containing a substance having a polysiloxane structure and inorganic particles having insulating and heat-dissipating properties, curing the composition, then bonding a copper foil to the cured composition, and partially removing the copper foil, thereby forming a wiring layer.

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.

A method of manufacturing a tubular member having a non-constant thickness by ironing at least a portion of the tubular material. The ironing apparatus can have a punch and a die, and the die can have a convex and concave side surface opposing the punch. The method can include bending an axial end portion of the tubular material to form a bent portion. The tubular material can then axially engage the die at the bent portion, and then the punch can be moved relative to the die to iron at least a portion of the tubular material.

Method of manufacturing a radially corrugated expander-spacer for a piston oil ring assembly, having inner and outer crowns alternately and successively laid, which can prevent its both terminal ends from nesting together during assembling of the piston oil ring assembly. The inner crowns each includes an inner peripheral piece and an opening having a circumferential width larger than that of the inner peripheral piece, and the outer crowns each includes an outer peripheral piece and an opening having a circumferential width larger than that of the outer peripheral piece. The manufacturing method comprises the steps of filling thermosetting synthetic resin having bonding force with respect to metals into the openings of inner crowns at both terminal ends of the expander-spacer, and thereafter, setting the thus filled thermosetting synthetic resin so that the resin is fixedly secured to the openings of the inner crowns at both terminal ends of the expander-spacer. The resin is preferably fixed by irradiating ultraviolet rays thereto.

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.
