Abstract: A micro array chip is formed by high-speed injection molding. A chip body has a thickness of 1 mm and each well has a capacity of 1.2 &mgr;L with the bottom having a wall thickness of 250 &mgr;m. An opening of each well is surrounded by an annular protrusion part, which is raised from a surface of the chip body by a height of 200 &mgr;m. The openings of wells may be closed with a sheet of sealant made of aluminum or a resin. An overall shape of the micro array chip is rectangular and is a flat plate with a level bottom surface. Therefore, the micro array chip can be used with a heat block in flat plate form, which is independent of chip specifications such as a number of wells and their shape.

Abstract: The object of the present invention is to provide a safety device for car seat which lies down instantaneously and converts a infant, a child, or an old person into a safe stance, reacting with an impact given in a front/rear collision, so as to protect the infant, child or old person safely against the impact in the front/rear collision. To achieve this object, the present invention comprises a seat for infant/child installed on a conventional car seat and lying down with reacting to the impact and sliding forward, a locking member maintaining a normal stance of the seat for infant/child, and a impact reaction member releasing a locking between the seat for infant/child and the locking member as the impact occurs. Therefore, by having the seat for infant/child lain down against the transmitted impact in the front/rear collision, the danger from the impact could be avoided, and thus the infant, child or old person could be protected more safely.

Abstract: A semiconductor laser device and optical pickup in which the reflectance of the side beam at a header portion will not adversely affect the characteristics of the optical pickup, and superior in productivity, and a method of fabricating such a semiconductor laser device are obtained. A reflector is attached on a side beam incident region of a leading end plane of a header mounted with a laser chip that emits a laser beam.
