摘要： Improved light reflector apparatus for use in an electronic flash unit or the like is formed by an injection molding operation, which causes both precise shaping of a reflector and accurate mounting of the reflector securely within a housing. A light-reflecting flexible sheet is placed in a mold so that its light-reflecting front surface is centrally positioned adjacent a mold forming surface. The forming surface, which is larger than the sheet, has a contour adapted for shaping the sheet to reflect light into a beam of illumination. Liquid plastic is injected into the mold under pressure against the opposite surface of the sheet, thus pressing its light-reflecting surface into intimate contact against the forming surface. Because the sheet is smaller, the border of the forming surface is not covered by the sheet. Plastic flows beyond outer edges of the sheet against the uncovered border of the forming surface. The intimate contact between the forming surface and the sheet blocks plastic from leaking therebetween onto the light-reflecting surface. The plastic solidifies to form a housing having a supporting body underlying the sheet and a shoulder, integral with the supporting body and contiguous with and surrounding outer edges of the sheet. The shoulder traps the sheet against the underlying supporting body for maintaining the contour of the sheet caused by the molding surface.

摘要： A camera comprising a door with an exterior viewing opening for viewing readable information appearing on a photographic article such as a film cartridge in the camera, and an interior light-trapping gasket that surrounds the viewing opening to confine ambient light entering the viewing opening when the door is closed, is characterized in that the viewing opening is extended along the door to hold a label at a particular portion of the viewing opening that does not interfere with ambient light entering the viewing opening to view the information.
摘要翻译：一种照相机，包括具有外部观察开口的门，用于观察出现在相机中的诸如胶片暗盒之类的照相物品上的可读信息，以及内部光捕获垫圈，其围绕观察开口限制环境光进入观察开口门被关闭，其特征在于，观察开口沿着门延伸以将标签保持在观察开口的特定部分处，该标签不会干扰进入观察开口的环境光以观察信息。

摘要翻译：通过注射成型操作形成用于电子闪光单元等的改进的光反射器装置，其引起反射器的精确成型和将反射器准确地安装在壳体内。将光反射的柔性片材放置在模具中，使得其光反射的前表面位于邻近模具形成表面的中心定位。大于片材的成形表面具有适于使片材成形以将光反射成光束的轮廓。液体塑料在压力下被压在模具的相对表面上，从而将其光反射表面压紧成形表面。由于片材较小，成形表面的边界不被片材覆盖。塑料流动超过成形表面的未覆盖边缘的片材外边缘。成形表面和片材之间的紧密接触阻止塑料在其之间泄漏到光反射表面上。塑料固化以形成具有在片材下面的支撑体的壳体和与支撑体一体的肩部，并与片材的外边缘邻接并围绕其周边。肩部将片材收集在下面的支撑体上，以保持由模制表面引起的片材轮廓。

摘要： An electromagnetic actuator includes a core made of a soft magnetic material, a permanent magnet located between a pair of ends of the core, the permanent magnet being supported for movement, and an electrically conductive coil wrapped about a portion of the core. The reluctance of the core is adjustable to alter movement of the permanent magnet as a function of time upon application of electrical current to the coil of the electromagnetic actuator.
