Abstract: A computer device, a setting method for a memory module, and a mainboard are provided. The computer device includes a memory module, a processor, and the mainboard. A basic input output system (BIOS) of the mainboard stores a custom extreme memory profile (XMP). When the processor executes the BIOS, so that the computer device displays a user interface (UI), the BIOS displays multiple default XMPs stored in the memory module and the custom XMP through the UI. The BIOS stores one of the default XMPs and the custom XMP to the memory module according to a selecting result of the one of the default XMPs and the custom XMP displayed on the UI.

Abstract: A liquid composition includes copper particles, an organic acid, and a solvent. The copper particle has a particle size of 0.5 ?m˜30 ?m which falls in a micron scale. The liquid composition performs reaction sintering by redox reactions taken place between the copper particles and an organic acid solution at a low temperature of 150° C. in order to produce a dense copper layer and improve the conventional micron-scale copper particles that requires a protective atmosphere for the high-temperature sintering before achieving the required densification. This liquid composition also prevents an excessive oxidation of the nano copper particles during the low-temperature sintering process and a failure of the dense sintering. Due to the agglomeration of nano copper particles, some areas have to be sintered first, so that the sintered products have a good uniformity of tissue and a low resistance below 0.04 ohm per square (?/?).

Abstract: A seal may be applied to a slightly uneven surface of an article and has a base and a die. The base has a flat end surface and a resilient metal board. The resilient metal board is made of a mixture of metal and rubber or plastic and is attached evenly to the flat end surface. The die is resilient, is mounted detachably and evenly to the base and has a resilient magnetized plate. The resilient magnetized plate is made of metal particles and rubber or plastic, is attached evenly to the die and is mounted detachably and evenly to the resilient metal board on the base. The seal with the resilient metal board and magnetized plate can safely and easily seal slightly uneven surface either in a document itself or from a surface on which the document rests.

Abstract: The invention discloses a combined pencil sharpener and an ink stamp being able to give off light. The invention includes a pencil sharpener and a stamp which are slidably engaged together. When a pencil is inserted into an opening of the pencil sharpener, it will move the sharpener towards the stamp and then conduct a circuit contained in a housing of the stamp to allow an LED to give off light. The invention will not only increase the attractiveness of the sharpener but also be very helpful to teach a young user to sharpen a pencil.

Abstract: A writing instrument with sound and illumination functions has a case with an ink cartridge. A chamber is mounted on the case. A buzzer and an IC board are installed in the chamber. The IC board has an LED mounted on the upper surface and two battery seats with a battery in each seat mounted on the bottom surface. When writing, the circuit consisting of the buzzer, the LED, the IC board and the batteries is completed so that the LED emits light and the buzzer makes a sound or plays music.

Abstract: The structure of an ink stamp emitting light and sounds has an LED and a speaker contained in a housing and electrically connected to a circuit board. When the ink stamp is pressed downward, the LED and the speaker will respectively give off light and sounds.

Abstract: An illuminating ball pen includes an ink cartridge received in a barrel, a joint pipe threadly engaged on a top end of the barrel, a top seat which is easily connected/disconnected with an upper end of the joint pipe, a lighting assembly provided in the top seat and with a lighting element protruded into a transparent globe a the top of the top seat, and a stamping seat secured in a lower end of the top seat. The lighting element of the ball pen will light or flash when a user is writing or stamping with the ball pen, or shaking the ball pen up and down.

Abstract: A rotary stamp including a casing having an opening, an impression wheel revolvably mounted within the casing and partially projected out of the opening of the casing and having an annular groove around the periphery, and an ink-absorbed absorptive belt stamp mounted around the annular groove of the impression wheel a slip joint and turned by the impression wheel over something to mark it.
