摘要:
The polarizer of the present invention is composed of mediums having different refractive indices, by which ordinary light in incidented light is wholly reflected at a boundary between laminated medium I and medium II and extraordinary light is transmitted through the medium II. The medium II is so arranged as to be almost 45.degree. to the light axis, and thickness of the medium II is selected as a value with which the medium II works as a half wave length plate to the transmitting light. The polarizer, which has high transparency by reduction of absorption and is able to make most of incident light be similarly polarized light, is obtained. A polarizer for and apparatus for bright liquid crystal display, which is able to be enlarged to a large size display without light absorption, can be provided.

A display device, which is adapted for time-division driving and is free from occurrence of crosstalk, includes a pair of substrates which are arranged to be opposite to each other and at least one of which is transparent, electrodes provided respectively on surfaces of the substrates facing each other, and a material which is sandwiched between the electrodes and the light transmitting quantity of which is changed by an electric field applied between the electrodes. The electrodes formed on the surfaces of the substrates facing each other constitute scanning electrodes and signal electrodes which intersect each other to form display portions. The signal electrodes constitutes independent electrodes formed independently of each other in units of display portions. Outside leads of the respective independent electrodes are passed through the substrate provided with the electrodes and are led out to the back surface of the substrate.

The present invention provides a heat transfer process and a heat transfer ink sheet, where a letter or image or both is recorded by selectively heating a heat transfer ink sheet having ink layer regions each containing a sublimable or vaporizable dye by heating by a thermal head controlled by a controlling means, thereby selectively heat transferring the sublimated or vaporized dyes onto a recording sheet, and is characterized by heat transferring a precoating layer for receiving the dyes from the ink sheet onto the recording sheet before the heat transfer recording, and then pressing the ink sheet on the transferred precoating layer on the recording sheet and heating the ink sheet by the thermal head, thereby sublimating or vaporizing the dyes from the respective ink layers onto the precoating layer and forming the letter or image or both on the recording sheet.

A method for quantifying LDL cholesterol, by which LDL cholesterol is separately quantified simply without requiring complicated centrifuge operation is disclosed. The method for quantifying cholesterol in low density lipoprotein according to the present invention comprises a first step of erasing cholesterol in high density lipoprotein, very low density lipoprotein and chylomicron in a test sample, and a second step of quantifying cholesterol remaining in the test sample.
摘要:
The invention relates to a humidity sensor of electric resistance type whose electric resistance changes in accordance with an ambient humidity, characterized by a protective film of silicone resin provided on the surface of a humidity-sensitive material, and to a method for preparing the same. The protective film of silicone resin is formed by applying a varnish of siloxanes to the humidity-sensitive material and subjecting the varnish to reaction. The varnish can be of one-part curing system or two-part curing system, and desirably the reaction of siloxanes is a cross-linking reaction. The formed protective film is not influenced by swelling or shrinking of the humidity-sensitive material, and is prevented from flowing off due to a temperature rise, or from deposition of dusts, etc.
