Disclosed is a method of manufacturing a lamp. The lamp is formed by arranging lamp electrodes in a lamp body provided therein with a discharge space and a fluorescent material. A first conductive layer is formed on a base conductor and a second conductive layer is formed on the first conductive layer by allowing the first conductive layer to react with a reaction solution including a solvent and metallic salt, thereby forming the lamp electrodes.

Disclosed herein are a method and an apparatus to identify alpha-emitting radionuclides and to measure absolute alpha radioactivity using a low temperature detector. A 4π metallic absorber which encloses a radioactive material containing alpha-emitting radionuclides absorbs the total alpha decay energy in the form of thermal energy. The corresponding temperature changes are measured by a low temperature detector attached to the 4π absorber with high energy resolution. The identification of alpha-emitting radionuclides is declared by comparing the measured temperature signal with characteristic decay energy of radionuclides. The absolute amount of the radionuclides is determined by counting the number of the pulses for each of the identified nuclides.

A method for programming a non-volatile memory device includes applying a first program-verify voltage to a first word line to determine whether or not memory cells associated with the first word line have been programmed successfully. A second program-verify voltage is applied to a second word line to determine whether or not memory cells associated with the second word line have been programmed successfully. The second program-verify voltage is different from the first program-verify voltage. The first and second word lines are associated with the same word line switching unit.

At the time of a program of a NAND flash memory device, a re-program is performed on a cell connected to the last word line after program and program verification are completed. Thus, threshold voltage distributions of the cell connected to the last word line can be controlled to have a narrow width in the same manner as that of other cells. It is therefore possible to secure the read margin of a chip and to improve the yield. Accordingly, the durability and reliability of devices can be improved by threshold voltage distributions controlled to have a narrow width as described above.

Disclosed herein is a light guide plate for keypad backlight panels, which is mounted at the rear of a keypad having numerals or characters printed thereon for supplying light emitted from a light source mounted at one side of the keypad to the keypad. The light guide plate is made of polycarbonate and is provided at the rear surface thereof with a concave-convex pattern, the density of which is increased as pattern elements of the pattern become more distant from the light source, such that light emitted from the light source is reflected and is uniformly supplied to the keypad, the pattern being formed on the light guide plate by hot stamping, injection molding, or micro blasting. The density of the pattern is adjusted by adjusting the distance between the pattern elements of the pattern or by adjusting the size of the pattern elements of the pattern. Consequently, it is possible to manufacture a keypad module in a slim structure or a curved structure. It is also possible to manufacture a keypad module that is capable of uniformly supplying light.

A tunneling method includes: managing a session entry table for storing information used for multicasting data transmitted from a first network having a first address format to a second network having a second address format different from the first address format; and tunneling multicasting data, generated by the first network, to the second network in accordance with the session entry table. Furthermore, a tunneling apparatus includes: a first interface adapted to interface with a first network having a first address format; a second interface adapted to interface with a second network having a second address format; a session entry table adapted to store information used for multicasting data transmitted from the first network to the second network; a table manager adapted to add a new entry, and to update and delete information of a previously stored old entry, with respect to the session entry table in accordance with information of the data transmitted and received via the first and second interfaces; an encapsulator adapted to encapsulate data of the first address format into data of the second address format to transmit the data from the first network to the second network; and a packet parser adapted to determine whether or not the data received via the first interface is multicasting data, and controlling the encapsulator and the table manager in accordance with the determination result.
摘要:
A vehicle levelling device includes a vehicle body with a rear section and a rear axle carried under the rear section of the vehicle body to provide support therefor. A support yoke is hingedly mounted to the vehicle body for pivotal movement about a transverse axis in a vertical plane. The support yoke holds the rear axle in a manner that the rear axle can rotate about a longitudinal axis. A hydraulic cylinder is attached to the vehicle body at a first end and to the support yoke at a second end so that it can be operated to lower or raise the rear section of the vehicle body with respect to the rear axle to thereby bring a tilted forklift into a horizontal position. Operation of the hydraulic cylinder is controlled by an electronic controller which in turn receives a tilt signal from a tilt sensor.
