Abstract: The present disclosure discloses a memory access interface device. A clock generation circuit generates reference signals. A transmitter transmits an output command and address signal to a memory device according to the reference signals. A signal training circuit executes a training process in a training mode that includes steps outlined below. A training signal is generated such that the training signal is transmitted as the output command and address signal. The training signal and the data signal generated by the memory device are compared to generate a comparison result indicating whether the data signal matches the training signal. The comparison result is stored. The clock generation circuit is controlled to modify a phase of at least one of the reference signals to be one of a plurality of under-test phases to execute a new loop of the training process until all the under-test phases are trained.

Abstract: The present disclosure discloses a memory access interface device. A clock generation circuit generates reference clock signals. Each of access signal transmission circuits each includes a duty cycle adjusting circuit, a duty cycle detection circuit, a frequency division circuit and an asynchronous first-in-first-out circuit. The duty cycle adjusting circuit performs duty cycle adjustment on one of the reference clock signals according to a duty cycle detection signal to generate an output clock signal having a duty cycle. The duty cycle detection circuit detects a variation of the duty cycle to generate the duty cycle detection signal. The frequency division circuit divides a frequency of the output clock signal to generate a read clock signal. The asynchronous first-in-first-out circuit receives an access signal from a memory access controller and outputs an output access signal according to the read clock signal to access the memory device accordingly.

Abstract: A storage rack structure and a storage panel module thereof are disclosed. The storage panel module includes an inclined carrying panel, a rolling unit and a plurality of storage boxes. The inclined carrying panel has an inclined top wall and a first lateral side and a second lateral side arranged at two sides of the inclined top wall, and a height of the inclined top wall is gradually reduced from the first lateral side to the second lateral side. The rolling unit is disposed on the inclined top wall and crossly arranged between the first lateral side and the second lateral side. The storage boxes are disposed on the inclined top wall and the rolling unit and adjacently arranged between the first lateral side and the second lateral side. Accordingly advantages of easily taking out medicines and efficiently managing expire dates of the medicines are provided.

Abstract: A casing of an electronic apparatus has a body and an electromagnetic absorption structure combined with a surface of the body. A manufacturing method for a casing of an electronic apparatus forms a body first, and then disposes an electromagnetic absorption structure on a surface of the body. Another manufacturing method for a casing of an electronic apparatus includes disposing an electromagnetic absorption layer on a surface of a film to form an electromagnetic absorption structure, and then placing the film into a set of molds and using an insert-molding technology to have injection material to form a body combined with the electromagnetic absorption structure to obtain a casing of an electronic apparatus. The casing absorbs electromagnetic waves, and the electromagnetic waves are transformed into heat energy to dissipate and vanish, thereby eliminating the existence of the electromagnetic waves.

Abstract: A method of manufacturing a casing of an electronic product with surface decoration thereon has a step of designing a decorative image, a step of printing a decorative layer on a film, and a step of injection molding. The decorative image is designed by using a computer. The decorative image is transformed into a decorative layer and the decorative layer is printed on a film by using a computer and a printer connected with each other. The casing of an electronic product with surface decoration thereof is obtained by applying in-mold decoration and injection molding technology, which combines injection material with the film.
