Title: Bottle
Inventor: NAGAMINE TAKAKO
IPC: B65D1/02
Filed: 1990-05-10
Abstract: PURPOSE:To make it possible to dampen impact waves being generated in a filled liquid in a bottle, and prevent cracking or rupture to a bottle due to unexpected impact from generating by processing the internal surface of a bottle to be uneven. CONSTITUTION:For an internal surface 1a of a bottle, the glass surface is processed to be finely uneven, and the unevenness faces random directions. When a medicinal liquid 4 in the bottle is fiercely shaken by lifting or moving a bottle main body 1 suddenly, in the medicinal liquid 4, a pressure direction 5 as impact wave is generated. Since the surface of the internal surface 1a of the bottle to receive this pressure has fine unevenness, the surface area becomes larger, and the impact becomes smaller comparing with a case in which impact with the same strength is added to the internal surface of a bottle, which is not processed to be uneven. Also, since the unevenness faces random directions, reflecting directions of impact become random also, and the impact is dampened by mutually setting off the pressure directions.

IPC: G03F1/22
Filed: 1992-05-14
Abstract: PURPOSE:To enhance the positional accuracy of an X-ray absorber pattern by a method wherein a silicon substrate is etched back, a rear protective layer is then formed in an etched part, the X-ray absorber pattern is formed on the surface on the rear side and, after that, the rear protective layer is removed. CONSTITUTION:A silicon substrate 1 is etched back by making use of a thin film 4 for mask use as a mask; a thin film which is formed of a thin film 2 for membrane use and of an X-ray absorber layer 3 is formed. In the process, the thin film 2 for membrane use is shrunk due to an internal stress; it becomes stable in a state that a very small warp has been caused in a silicon frame. As a result, a patterning operation is performed after an etching-back operation. As a result, it is possible to restrain that a strain is caused in the film more than that, and the positional accuracy of a pattern is increased. The X-ray absorber layer 3 is patterned while a rear protective layer 5 has been applied. Since the rear of the membrane is provided with the rear protective layer 5, the membrane which is composed of the thin film 2 for membrane use and of the X-ray absorber layer 3 is not destroyed.
