A light-emitting device (10) using an LED is proposed. This light-emitting device (10) is provided with a packaging substrate (1), a light-emitting element (2) which is mounted on this packaging substrate (1) with its face down, a fluorescent member (3) that is arranged face to face with a light-extracting surface (S) of the light-emitting element (2) without contacting the light-emitting element (2) and an optical member (4) which receives light that has been emitted from the light-emitting element (2) and made incident thereon through the fluorescent member (3), and aligns the incident light toward the outside of the device. Light, emitted from the light-emitting element (2), is made incident on the fluorescent member (3) to excite the fluorescent material so that the fluorescent material re-emits light having a wavelength different from that of the incident light. Those light rays, emitted from the light-emitting element (2), which have not been absorbed by the fluorescent member (3) and have passed through the fluorescent member (3) and those light rays that have been emitted from the fluorescent material are made incident on the optical member (4) and are aligned. Because the fluorescent member (3) is not made in contact with the light-emitting element (2), it does not receive the heat from the light-emitting element (2) through heat conduction, and consequently becomes less susceptible to degradation due to heat. Moreover, with the face-down mounting structure, the fluorescent member (3) and the optical member (4) can be placed closer to the light-emitting element (2) as long as they dose not contact the light-emitting element (2). Consequently, the service life of the fluorescent material or the fluorescent-material-mixed resin that tends to deteriorate can be lengthened, lights can be extracted more efficiently, and light rays can be properly aligned in a predetermined direction.

The nature of this invention encompasses the creation of a capillary gas chromatography (GC) column assembly and a thermal modulator used to heat or cool the column assembly in a very thermally and chromatographically efficient manner. The GC column assembly described herein consists of capillary GC column material, such as fused silica or metal capillary tubing, which is constrained to lie in a flat, ordered, spiral pattern and then encased between two thin opposing surfaces. The resulting column assembly is flat, dimensionally stable and can be very efficiently thermally modulated. The resulting column assembly also takes up very little space, has very little thermal mass, and can be easily and accurately manufactured. The column assembly can be adapted for chromatographic use by affixing it to the surface of a thermal modulator described herein by means of adhesive force or by mechanical compression, and then by attaching the free ends of the exposed column material to the input and output ports of the chromatographic device. The temperature of the thermal modulator and capillary column assembly is to be controlled by the chromatographic device or by standalone temperature controlling electronics. The thermal modulator described herein contains an element for temperature modulation of the capillary column assembly to which it is attached and a temperature sensing element for providing accurate temperature feedback to the controlling electronics. The overall result of this when coupled to a chromatographic device is maximally efficient chemical separations in a small space with minimal power consumption.

An apparatus and system are disclosed for protecting a power distribution unit from an electrical fault. A fuse interrupts a flow of electrical current in response to the electrical current rising above a current rating of the fuse. A current sensor measures the amplitude of the electrical current and outputs a current amplitude signal. A relay interrupts the flow of electrical current in response to an OFF signal. A fault module receives the current amplitude signal and sends the OFF signal to the relay in response to the amplitude of the electrical current exceeding a threshold value. The relay, the fuse, and the threshold value are selected so that a switching time of the relay is less than an opening time of the fuse for an amplitude of the electrical current between the threshold value and a maximum fault current value, so that the relay prevents the fuse from opening.

A linear motor for optical systems, for example, endoscopes, is described. The motor has a stator with a magnetic guiding member and two adjacently disposed coils which are energized in opposite directions. Furthermore permanent magnets polarized in opposite directions and in the axial direction are provided on both sides of the pair of coils. The armature of the motor comprises a permanent magnet which is polarized in the opposite direction to the permanent magnet of the stator and is connected to a pole piece at each end. The pole pieces are arranged so that in the rest position each pole piece lies at the centre of one of the coils. By applying current to the coil, the armature can be displaced from a rest position in the longitudinal direction.

The UV irradiating unit has either a semiconductor laser or an LED, which enables emitting light the peak wavelength of which includes any one of wavelengths in an ultraviolet range which allow to cure the UV ink.

This invention is a method and apparatus for drying wet objects, comprising passing air through the wet objects thereby having air absorb moisture from said wet objects; compressing the air adiabatically, thereby heating it; extracting heat from the air by passing it through the hot side of a heat exchanger thereby cooling it; expanding the air adiabatically, thereby cooling it further, below its dew point; separating the condensate from the air; restoring to the air all or part of the heat by passing it through the second side of the heat exchanger; and redirecting all or part of the air back to the wet objects thereby forming a loop in the flow of the air.

A superconducting short circuit current limiter (40a) for an alternating current system includes AC reactors having superconducting direct current bias windings (4a, 4b) that at normal conditions maintain the reactor's cores in saturated state. There are at least two AC coils (3a, 3b) for each phase operating at opposite half periods or at both half periods. The reactor may also have an additional feedback coil (42a, 42b) that at least partly compensates for the bias field of the superconducting coil at fault conditions enhancing a limiting capacity of the reactor. The reactor's core can be configured for decreasing its dimensions and mass as compared with known devices and for decreasing core losses. High voltage/high current devices include several standard modules connected in series or/and in parallel. A positional relationship of the modules is defined for decreasing necessary numbers of Amp?re-turns of superconducting and non-superconducting coils.

If desired, the display device may be controlled so as to provide a substantially constant amount of illumination when the object is viewed or intended to be viewed. A method of protecting an object using the display device is also provided.
