  • Patent number: 6938174
    Abstract: The present invention pertains to a computing system having an input system with local storage interfaced with a computing device, wherein input information is transferred from the digitizer input system to the interfaced computing device based on an adaptive transfer policy that extends the battery life of the interfaced computing device. The interfaced computing device may be a PC. The digitizer input system can support automated, selective transfer policies based on the power management configuration of the PC interfaced with the digitizer input system and user-selected transfer policies.

  • Publication number: 20050158586
    Abstract: A powder for an underlayer of a coating-type magnetic recording medium comprises acicular iron oxide particles having an average major axis length in the range of 20-200 nm, has a specific surface area measured by the BET method of 30-100 m2/g and has a powder pH of not greater than 7. The underlayer powder preferably contains 0.1-5.0 wt % of P and optionally contains an amount of R (where R represents one or more rare earth elements, defined as including Y) such that R/Fe expressed in atomic percentage (at. %) is 0.1-10 at. %. The iron oxide powder enhances the properties required of a powder for forming the underlayer of a multi-layer structure coating-type magnetic recording tape, most notably the surface smoothness and strength of the tape.

  • Publication number: 20050037590
    Abstract: The present invention provides an inhibition to the short circuit between the bit line and the capacitance contact, without employing a self alignment contact (SAC) process, in which a hard mask is formed on the upper surface of the bit line and a side wall formed on the side surface of the bit line by etching back a nitride film. A bit contact interlayer film of the conventional semiconductor device which does not have the SAC structure is etched off except the portion where bit line is formed, and then direct nitride film is formed on the entire surface of the top surface and the side surface of the bit line so as to cover the bit line in a same processing step. Since the film thickness of the nitride film disposed on the upper surface of the bit line is designed to be substantially the same as that disposed on the side surface of the nitride film, the height of the bit line itself can be reduced, and thus a further miniaturization becomes possible.

  • Patent number: 6839853
    Abstract: To obtain a method for controlling power of a computer, a power control apparatus, and the computer which can prevent a user from feeling uneasy unnecessarily and inhibit a power-on problem from arising again. When the power switch is depressed, the power-on self test (POST) starts and if there is no error detected by that test in connection with the initialization of the IC, the operating system OS is loaded to make the computer operative (steps 200 through 208). If there is any error detected, a determination is made whether that error occurs as frequently as or more frequently than a predetermined number of times. If that error occurs as frequently as or more frequently than the predetermined number of times, an error indication is displayed and then the process ends. If that error occurs less frequently than the predetermined number of times, the error history is stored and then a setup for stabling the hardware operation is selected.

  • Patent number: 6825889
    Abstract: In a liquid crystal device and a projection display device using the liquid crystal device as a light valve, for the purpose of preventing light incident from opposite the clear viewing direction from affecting the display, in a liquid crystal device (1), an optical center position (411) of a microlens (41) formed on a counter substrate (30) is offset toward the clear viewing direction as viewed from a center position (211) of a first opening area (21) formed for each pixel on the side of an active matrix substrate (20). For this reason, light incident on the counter substrate (30) from the direction inclined in the clear viewing direction is emitted from the active matrix substrate (20); however, light incident from the direction inclined opposite to the clear viewing direction that causes the degradation of contrast is not emitted from the active matrix substrate (20) and does not affect the display.

  • Patent number: 6569766
    Abstract: A method for forming a silicide of a metal with high-melting-point in a semiconductor device includes the step of removing a higher-density impurity area which acts for prevention of forming the metal-silicide layer on the surface of the impurity-diffused region between the steps of implanting impurities to form an impurity-implanted region and annealing for reactions of cobalt and silicon of the diffused layer. The above-mentioned method of forming the metal-silicide layer on the surface of the impurity-diffused region proceeds smoothly to thereby prevent degradation of the initial gate withstand voltage and a higher sheet resistance.

  • Publication number: 20020086493
    Abstract: A manufacturing method of a semiconductor device having a CMOS logic circuit portion and a DRAM portion mixedly mounted on one chip. Preferably, the DRAM portion has a cylinder structure capacitor element. In the manufacturing method, the polysilicon film is formed on an interlayer film and on an inner wall of a cylinder-shaped opening formed in the interlayer film. Spherical or hemispherical grains called HSG are formed on the polysilicon film. The polysilicon film and the HSG on an upper surface of the interlayer film are removed while the polysilicon film and the HSG on the inner wall of the cylinder is retained. By performing these steps in this order, the HSG is reliably formed on the inner wall of the cylinder without fail. Therefore, a miniaturized capacitor element having high capacitance may be formed in a semiconductor device with a CMOS logic circuit portion and a DRAM portion mixedly mounted on one chip.
