Abstract: An image forming apparatus, a microcontroller, and methods for controlling the image forming apparatus and the microcontroller are provided. The microcontroller include: a memory controller which is connected to an external memory operating in a self-refresh mode if a normal mode changes to a low power mode, performs a control operation by using the external memory in the normal mode, and outputs a preset signal which is to cancel the self-refresh mode if the low power mode changes to the normal mode; a memory interface unit which transmits the preset signal to a main memory; and a signal detector which detects whether the preset signal has been output. Here, the memory controller powers off the memory interface unit if the normal mode changes to the low power mode and powers on the memory interface unit if the low power mode changes to the normal mode, and the output of the preset signal is detected by the signal detector.

Abstract: Provided is a parallelism control apparatus of a movable platen of an electric injection molding machine, to which a new arrangement type using a wedge to control the parallelism of a movable platen is applied to reduce the size of the parallelism control apparatus, ensure an installation space, and solve a difficulty during installation, which ensures rigidity of the movable platen in directions of forward and rearward movements, and enables parallelism adjustment and firm position fixing by controlling a vertical amount, a horizontal amount, and a combination of vertical and horizontal amounts even in a narrow space, thereby further enhancing precision and quality reliability of molded products.

Abstract: The present invention provides a valve lifter, including a buffer layer, a Me diamond-like carbon layer having a thickness of 0.3˜0.6 ?m, and a diamond-like carbon layer having a thickness of 1˜1.5 ?m and a SP3 bonding fraction of 60˜70%, which are sequentially formed on a base body which is subjected to carbonitriding treatment. The valve lifter can exhibit superior low-friction characteristics and wear resistance.

Abstract: A precipitation-hardened stainless maraging steel which exhibits a combination of strength, toughness, and corrosion resistance comprises by weight about: 8 to 15% chromium (Cr), 2 to 15% cobalt (Co), 7 to 14% nickel (Ni), and up to about 0.7% aluminum (Al), less than about 0.4% copper (Cu), 0.5 to 2.6% molybdenum (Mo), 0.4 to less than about 0.75% titanium (Ti), up to about 0.5% tungsten (W), and up to about 120 wppm carbon (C), the balance essentially iron (Fe) and incidental elements and impurities, characterized in that the alloy has predominantly lath martensite microstructure essentially without topologically close packed intermetallic phases and strengthened primarily by a dispersion of intermetallic particles primarily of the eta-Ni3Ti phase and wherein the titanium and carbon (Ti) and (C) levels are controlled such that C can be dissolved during a homogenization step and subsequently precipitated during forging to provide a grain-pinnning dispersion.

Abstract: High-strength, low-hysteresis TiNi-based shape-memory alloys (SMAS) employing fully coherent low-misfit nanoscale precipitates, wherein the precipitate phase is based on an optimized composition for high parent-phase strength and martensite phase stability, and compensating the stored elastic energy through the addition of martensite stabilizers. The alloys, with a yield strength in excess of 1200 MPa, are useful for applications such as self-expanding stents, automotive actuators, and other applications wherein SMAs with high output force and long cyclic life are desired.
