Abstract:
When an insulator is irradiated with an electron beam, a pulse-shape voltage is applied to the insulator from a pulse power source. As a result, a charge-up state of the insulator can be prevented. If an object which must be subjected to surface modification is an insulator, the object can effectively be irradiated with the electron beam to perform the surface modification.
Abstract:
An optic system with at least one optic path modifying element, e.g. a prism, has at least one layer of low refractive index with a thickness of at least a quarter wavelength. The layers can include antireflection coatings and can comprise a multilayer structure laminated to the inlet/outlet faces of the optic elements. The combined effect of the layers is to provide a total layer of low refractive index.

Abstract:
In a non-contact IC card (1), a rectification circuit (17) rectifies an electromagnetic wave obtained via an antenna (10) and converts it into DC voltage while an electric dual-layered capacitor (18) rapidly accumulates power obtained by the conversion. The electric dual-layered capacitor (18) uses this electric energy to operate circuits such as a modulation/demodulation circuit (11), a CPU (12), a memory (13), a controller IC (14), and a driver IC (15) and rewrite information displayed on a display element (16) using cholesteric liquid crystal and ferroelectric liquid crystal.
Abstract:
PROBLEM TO BE SOLVED: To provide a surface light source device having a constitution and a structure in which color unevenness hardly occurs, even if respective light emission intensity distributions of light-emitting elements to emit three primary colors of light are different. SOLUTION: The surface light source device to illuminate a liquid crystal display device from the rear face includes a plurality of light-emitting element units. Respective light-emitting element units are constituted of at least one first light-emitting element assembly 10 which is composed of a first light-emitting element 11 and a first lens 12 and emits the first primary color, at least one second light-emitting element assembly 20 which is composed of a second light-emitting element 21 and a second lens 22 and emits the second primary color, and at least one third light-emitting element assembly 30 which is composed of a third light-emitting element 31 and a third lens 32 and emits the third primary color. Based on the respective light emission intensity distributions of the first light-emitting element 11, the second light-emitting element 21, and the third light-emitting element 31, a focal length and lateral magnification of the first lens 12, the second lens 22, and the third lens 32 are adjusted.

Abstract:
PROBLEM TO BE SOLVED: To enable to achieve a low power consumption while emitting light at the identical whiteness on the whole surface of the lighting region. SOLUTION: The memory 73 has a current value stored in which each region A ij of a backlight 12 has an identical whiteness and light-emitting luminance. The current control part 74 controls the current value which the power supply part 14 supplies to an LED 51R, LED 51G, and LED 51B in the region A ij so that it may be the current value stored in the memory 73. The pulse width determining part 71 determines the pulse width W of a pulse signal corresponding to the light-emitting luminance, and the pulse generating part 72 generates the pulse signal of the determined pulse width W, and supplies it to a switching element 53 in the region A ij . This device can be applied, for example, to a liquid crystal display device. COPYRIGHT: (C)2008,JPO&INPIT
