Abstract:
The present invention provides a cup lid including a top shield, at least two ring shields, and at least two snap-on components. The ring shields extending from a lower edge of the top shield downward are peripherally spaced from each other. Each snap-on component extends from the lower edge of the top shield downward and is arranged between two adjacent ring shields. Each snap-on component includes a U-shaped border, a tab, and at least one Y-shaped resisting member. The U-shaped border and the top shield define an opening. The tab extends from the U-shaped border outward. The Y-shaped resisting member extends from an interior of the U-shaped border upward and is bendably held in the opening. The cup lid can be fitted on a cup body or separated from the cup body through the Y-shaped resisting members without a further operation step for repeated utilization and environmental effect.
Abstract:
A clamp structure includes a base plate and a pair of jaws. The jaws extend respectively from two transverse sides of the base plate and form a jaw opening opposite to the base plate. An aperture is formed longitudinally in the center of the base plate, wherein the transverse width the aperture is wider than the jaw opening. Therefore, the workers can connect the conductive terminals and the ribbon conveniently by pulling them out from inside of the clamp structure.
Abstract:
A controller for a DDR PSRAM is provided. The controller includes a single rate processing unit, a double rate processing unit and a selector. The signal rate processing unit obtains a single data rate data according to a first data and a first clock. The double rate processing unit obtains a double data rate data according to a second data and a second clock that is two times the frequency of the first clock. The selector selectively provides any of the single data rate data and the double data rate data to the DDR PSRAM via a common bus according to a control signal.
Abstract:
A junction box includes a base, a cover snap-fitted into the base and a ventilation valve on the cover. The ventilation valve includes a first hollow cylinder that has a first inner bore having a first thread and a bottom having an open area that includes an annular flange; a second hollow cylinder; and a waterproof air-permeable membrane. The second hollow cylinder has a second thread on an outer surface thereof, a first end, a second end and a second inner bore. The first end has an annular groove. The waterproof air-permeable membrane is disposed between the first end of the second hollow cylinder and the bottom of the first hollow cylinder. A specific distance, smaller than an axial feeding amount of the first thread when being threaded by one turn, is formed between the top of the annular flange and the top of the annular groove.
Abstract:
A double data rate pseudo SRAM (DDR PSRAM) is provided. The DDR PSRAM includes a data receiver, a memory and an address decoder. The data receiver receives a first single data rate data from a controller via a common bus according to a clock, and receives a double data rate data from the controller via the common bus according to a data strobe signal from the controller. The address decoder decodes the first single data rate data to obtain an address of the memory. The data receiver stores the double data rate data into the address of the memory.
Abstract:
Disclosed are a photovoltaic battery module and a junction box assembly. The junction box assembly comprises a junction box and a base plate assembled with the junction box. The junction box comprises an insulated housing, the conductive terminals and the water-resistant members. The bottom of the junction box disposes the first openings. The water-resistant members disposed at the first openings have second openings whose areas are smaller than those of the first opening. The base plate disposes the third openings whose areas are smaller than those of the first opening. The third openings are assembled with the first openings and the second openings. Pairs of wing portions provided with a first preset distance, which is shorter than the width of the junction box, are aligned at both lateral sides of the base plate. The average width of the base plate is not greater than 50 millimeter.
Abstract:
A latched connector assembly includes a first connecting device and a second connecting device latched to each other. The first connecting device has a first casing and two terminal connectors received in the first casing. The first casing has first and second side walls. The first side walls have first engaging structures protruding outward. The second side walls each have an extending arm that has a second engaging structure. The second connecting device has a second casing and at least two terminal connectors received in the second casing. The second casing has third and fourth side walls. The third side walls have first engaging structures protruding outward. The fourth side walls each have a locking portion protruding outward for receiving the second engaging structures of the first connecting device. The terminal connectors are received, in opposite directions, in the first casing and the second casing, respectively.
