摘要:
A direct-type backlight device for a non-self-luminous image display panel has a light-emitting area corresponding to a display area of the image display panel. The light-emitting area is arranged by combining a plurality of backlight substrates each of which is provided with (i) a color sensor for detecting an incident light intensity and (ii) red, green, and blue LEDs whose respective light intensities are controlled in accordance with a detection result obtained by the color sensor. This arrangement allows reduction of brightness unevenness entirely in the light-emitting area of the backlight device.

Disclosed is a polymerizable composition comprising Component (a): a polythiocarbonate polythiol, Component (b): an episulfide compound, and optionally Component (c): an organic compound having a functional group that is reactive to the episulfide compound. The polymerizable composition can be cured to provide a polythioether having excellent optical properties (a high refractive index and a high Abbe's number) as well as excellent mechanical properties (a high bending distortion and a high glass transition temperature) and thus exhibiting excellent properties as an optical material.

A semiconductor laser has a ridge stripe region 150 with laminated structure 170 and first and second stripe-side regions 151, 152. The ridge stripe region 150 on a semiconductor substrate has a lower cladding layer, active layer, and upper cladding area. The first stripe side regions 151 are disposed on both outer sides of a ridge stripe region 150. The second stripe-side regions are disposed on both outer sides of the first stripe-side regions 151. A thickness from a lower surface of the upper cladding region to a lower surface of a buried layer 115 in the second stripe-side region is smaller than that in the first stripe-side region. A width of the first stripe side region 151 is larger in a middle portion of an oscillator than in a light emitting edge.

An energy difference picture processing method comprises the steps of using a semiconductor radiation detector; providing two discriminating levels; dividing X-rays, which have passed through objects, into two kind energy zones; counting X-ray photons to obtain an X-ray picture; assembling, with corresponding coefficients, S(H), S(L), {S(H)}.sup.x and {S(L)}.sup.y, which are exponential functions of the S(H) and S(L), respectively, where S(H) is a logarithmically converted version of a picture of counts in a higher energy band and S(L) is a logarithmically converted version of a picture of counts in a lower energy band; and performing addition, subtraction, multiplication and/or division on these terms to provide a picture in which a particular one of the materials constituting the objects is selectively extracted or removed.
摘要:
An optically sensing device is made up of the sensor materials that cause the value of birefringence to vary itself in accordance with external physical volume; a polarizer and an element provided with two total reflection surfaces causing the beam path to invert its direction by an angle of 180.degree.. The optically sensing device has the capability of setting the phase bias by applying the two total reflection surfaces causing the beam path to invert its direction by an angle of 180.degree.. Since each element has different functions, one functioning as a mirror and the other as a quarterwave plate, the optically sensing device is of extremely simple structure and is compact. In addition, since the optically sensing device provides a constant phase bias unlike the unstable performances of conventional quarterwave plates, it guarantees high-precision performance. Also, the use of inexpensive elements ensures reduced cost. In particular, by effectively combining such selected materials featuring photoelastic and electro-optic effects, the optically sensing device embodied by the present invention is extremely effective for detecting the physical volume of a wide variety of substances.
