Abstract: An adjustable carrier device is disclosed for storage and handling of fragile panel-like structures such as semiconductor wafers, ceramic substrates, LCD panel displays, printed wiring boards and the like. The device is adjustable to receive structures of different sizes without the use of any tools. The device comprises a slotted side wall for receiving one side edge of the panel-like structure, and a sized adjusting member having a semi-circular cross-section which is mounted on an offset pivot for movement toward or away from the slotted side wall to adjust to the size of the product. Slots are formed in the edge of the offset pivot member to receive another edge of the stored structure. A cover is provided for protection to enclose the panel-like structures when placed in the carrier device to prevent damage. No tools are required to adjust the device to different product sizes.

Abstract: A hatch cover is positioned in the hatch opening in the watch back over a battery receptacle in the watch module. The hatch cover is mechanically retained in the hatch opening by means of a snap-in friction fit. It has a rim on the watch back. A groove in the back adjacent the rim permits insertion of a tool to snap out the hatch cover. The watch back can remain on the case during battery change to hold the module in the case.
