摘要:
The present invention relates to a negative material for a non-aqueous rechargeable battery and a non-aqueous rechargeable battery including the same. The negative material for a non-aqueous rechargeable battery includes lithium vanadium oxide that is obtained by mixing a lithium compound such as lithium carbonate (Li2CO3) and a vanadium compound such as vanadium pentaoxide (V2O5) with an organic acid such as oxalic acid ((COOH2) to obtain an organic acid salt precursor and firing the organic acid salt precursor. The negative material for a non-aqueous rechargeable battery can improve charge and discharge characteristics of a non-aqueous rechargeable battery due to uniform composition.

A numerical controller in which similar icons are created without applying major load onto a memory. Among icon definition data displayed in areas F1 . . . , G1 . . . , H1 . . . , on frames A, B and C, the data that can be expressed by conversions, such as rotation, horizontal mirror image, vertical mirror image, horizontal-and-vertical mirror image, magnification/contraction retaining horizontal/vertical ratio, magnification/contraction varying horizontal/vertical ratio, black/white reversal, display in red, blue, yellow and green, with respect to one parent icon, are substituted with data indicating the conversion contents. It is possible to display many icons with a small storage capacity. The definition data of each icon can be previously written in a ROM and copied to a RAM when the power is turned on to be used for display.

Embodiments of the invention prevent demagnetization or degaussing of recorded magnetizations, even if a stray field is applied. In one embodiment, an output of a read head including a magneto-resistive effect element is inputted to a stray field detector through a DC amplifier and a DC filter. The stray field detector monitors dc components of the output from the read head, and escapes a head from above a magnetic recording medium.

The present invention enables recovery of data reading, even when thermal asperities or defective media will make it impossible to increase the number of retries or to read the data, occur in the AGC/PLL part. In a device for writing and reading information, when an error occurs in the region of the recording media where the AGC/PLL signal is written, and if that information is written continuously to several sectors, then data reading is performed by using the AGC/PLL of the following sector, without performing a retry, or by performing a minimum number of retries.

A cathode active material for a non-aqueous electrolyte secondary cell having a c-axis length of lattice constant of 14.080 to 14.160 Å, an average particle size of 0.1 to 5.0 &mgr;m, and a composition represented by the formula: LiCo(1−x−y)MnxMgyO2 wherein x is a number of 0.008 to 0.18; and y is a number of 0 to 0.18. This cathode active material is capable of maintaining an initial discharge capacity required for secondary cells and showing improved charge/discharge cycle characteristics under high temperature conditions.

A bobbin for superconducting coils, which is made of a fiber-reinforced plastic material containing: (1) a matrix resin; (2) a polyethylene fiber having a negative thermal expansion coefficient in the fiber lengthwise direction, the angle between the polyethylene fiber and the longitudinal axis of the bobbin being in the range of .+-.35.degree. to 90.degree.; and (3) a substance having an elastic modulus higher than that of the polyethylene fiber. The bobbin of the present invention is useful for superconducting coils because it only exhibits a quite low degree of deformation, even when used under external stress at cryogenic temperatures.
摘要:
An interactive numerical control apparatus is programmed by inputting data through keys on a control panel, and answering questions displayed on a display screen, to generate a numerical control program. The operator defines a blank shape and a part shape (steps S1, S2), and selects a primary machining operation or a secondary machining operation (step S3). A cutting region for the primary machining operation is defined in the same manner as with an ordinary two-axis lathe. For the secondary machining operation, the blank and part shapes are displayed in reverse (step S6), and a cutting region for the secondary machining operation is defined in the same manner as the cutting region for the primary machining operation is defined (step S7). Based on the necessary data and machining conditions that are defined, the interactive numerical control apparatus outputs numerical control data separately for the respective primary and secondary machining operations (step S8).

The method of preparing a negative active material for a non-aqueous electrolyte rechargeable battery includes mixing a vanadium compound and a lithium compound and then subjecting the mixture to first firing to obtain Li1.0(VxMy)1.0O2 having a layered halite type structure (where 0.5≦x≦1.0, 0≦y≦0.5, x+y=1, and M is selected from the group consisting of group 2 to 15 elements of the periodic table and combinations thereof); and adding a lithium compound to the Li1.0(VxMy)1.0O2 and then subjecting the resultant to second firing. The negative active material for a non-aqueous electrolyte rechargeable battery prepared according to the preparing method has high crystallinity, and excellent charge and discharge characteristics at a high rate.
