A light-emitting device which uses and LED having a light-emitting element being placed on a package substrate. The light-emitting element has a light-extracting surface. A fluorescent element which is formed by dispersing a fluorescent material in a transparent substance and is placed face to face with the light-extracting surface of the light emitting element and comprises a clearance gap in between. The light-emitting element generates light of a certain wavelength that emanates through the light-extracting surface into the fluorescent element where the wavelength is changed. The device further comprises an optical element which receives light from the light-emitting element through the fluorescent element and directs the light to the outside of the device.

An ultrasonic endoscope comprises an insertion portion comprising a distal hard portion which has: an endoscopic observation unit; and an ultrasonic observation unit having ultrasonic transducers arranged circumferentially on an outer circumferential section of the distal hard portion, wherein the ultrasonic observation unit comprises an ultrasonic-wave transmission / reception unit having an tunnel-shaped path which has an inner circumferential surface formed as a backing layer; a distal block is arranged on a distal side in an axial direction of the distal hard portion with respect to a location where the ultrasonic-wave transmission / reception unit is arranged, and distal ends of respective members constituting the endoscopic observation unit are fixed to the distal block; and part of the members which constitute the endoscopic observation unit are fitted so as to be partially protruded from an inside diameter of the tunnel-shaped path toward an outer circumferential side thereof.

A miniature spring-actuated stapler includes a tapered, flat power spring to store energy and eject staples. The power spring pivots at a rear of the stapler housing and includes three co-extensive arms terminating near the striker. As the L-shaped handle of the stapler is pressed, it acts on the center arm of the power spring to deflect it downward while the outer arms deflect upward. The arms are integral at a rear end and the outer arms are linked to the striker at the front. A tapered, flat reset spring disposed generally parallel to the power spring is used to reset the internal action. The housing includes open top and rear areas with the handle providing the enclosure thereof. A base assembly is slidably attached at a bottom of the stapler with an open position exposing a staple-loading chamber.

An optical equalizer / dispersion compensator (E / CDC) comprises an input / output for receiving a multiplexed channel signal comprising a plurality of channel signals of different wavelengths. An optical amplifier may be coupled to receive, as an input / output, the multiplexed channel signals which amplifier may be a semiconductor optical amplifier (SOA) or a gain clamped-semiconductor optical amplifier (GC-SOA). A variable optical attenuator (VOA) is coupled to the optical amplifier and a chromatic dispersion compensator (CDC) is coupled to the variable optical attenuator. A mirror or Faraday rotator mirror (FRM) is coupled to the chromatic dispersion compensator to reflect the multiplexed channel signal back through optical components comprising the chromatic dispersion compensator, the variable optical attenuator and the optical amplifier so that the multiplexed channel signal is corrected partially for equalization and chromatic dispersion compensation with respect to each pass through these optical components. The E / CDC components may be integrated in a photonic integrated circuit (PIC) chip. In several embodiments, a photonic integrated circuit (PIC) chip comprises an input into the chip that receives at least one channel signal having experienced chromatic dispersion, a chromatic dispersion compensator (CDC) that separates the at least one channel signal into separate wavelength components over a free spectral range (FSR) spanning only a signal channel width and subjects the wavelength components to a phase shift to change the wavelength group delay in the wavelength components and that recombines the wavelength components to reconstitute the at least one channel signal, and an output from the chip for the recombined at least one channel signal having reduced chromatic dispersion compared to the same channel signal received at the chip input. The CDC device may include a tuning section to vary the phase shift of wavelength components as they propagate through the device. Such a CDC device may include a Mach-Zehnder interferometer (MZI) or a cascaded group of Mach-Zehnder interferometers, or at least one arrayed waveguide grating (AWG) or at least one Echelle grating.

Disclosed is a vibration module for a portable terminal that includes a housing, a magnetic moving part movable in a first direction within the housing; an elastic member supported between the opposite ends of the magnetic moving part and inner walls of the housing, and a solenoid coil provided in the housing. The vibration module is positioned at one end of the moving section by the magnetic force of the magnetic moving part and an object around the magnetic moving part, allowing the vibration module to provide a user with a feeling similar to a click feeling via the acceleration produced at a stopping instant. In addition, when vibrating, the vibration module generates sufficient vibration power through acceleration at the instant of changing moving direction at the ends of the moving section, to provide an alarm function, such as an incoming call notification.

Porous ceramic catalyst supports or filters to be provided with catalyst coatings via oxide washcoating processes are pre-coated with polymer barrier layers to prevent washcoat nanoparticle intrusion into the microcracked and / or microporous surfaces of the ceramics, the barrier coatings being formed of hydrocarbon polymers that are soluble or dispersible in polar media, capable of forming neutral or hydrophilic surfaces on porous ceramic supports, and completely vaporizable at moderate washcoat stabilization or catalyst activation temperatures.

A method of controlling a rolling or coasting function of a vehicle with a drive train having a drive motor, an automatic or automated transmission, a controllable shifting means, a brake device and a drive speed control device. The vehicle speed is regulated by the drive speed control device and the braking device is activated, as needed, when driving on a downhill gradient section. To effectively and reliably use the rolling or coasting function in suitable driving situations, taking into account the influence of the driving speed control device, a rolling or a coasting condition for a downhill gradient taper is checked, when driving on the downhill gradient section, and, when the rolling or coasting condition is satisfied, the transmission controls interrupt the flow of power in the drive train before the vehicle entering a flat area, and / or before the driving speed control device generates an engine torque request.

The present invention relates to improved chemical additives for use in hydraulic fracturing fluids for the recovery of oil or natural gas entrained in deep-layer shale formations. Many chemical agents currently in use in such water / sand (or other proppants) mixtures could pose human and animal health risks if these chemicals migrate from the shale beds into the environment contaminating the water table, rivers, streams and lakes. The fracturing fluid chemical additives of this invention are designed to be retained or anchored in or near the deep shale layers and are prevented, or greatly delayed from upward migration. Specifically, many chemical additives required for proper fracturing fluid performance can be chemically bonded to inert particulate materials before incorporation into said fluids. The fracturing fluid chemical additives are able to perform their function in the shale fracturing process, and then become nearly permanently trapped in the shale layers protecting the environment above.
