摘要:
A recording sheet has a base and a receptive layer disposed on at least one surface of the base. The receptive layer contains at least a water-absorbent copolymer and said water-resistant graft copolymer whose main chain is polyvinyl alcohol. The water-absorbent copolymer absorbs inks, and the water-resistant graft copolymer makes the receptive layer resistant to discoloration, blurring, and gloss or luster irregularities. The water-absorbent graft copolymer comprises a graft copolymer produced by grafting a vinyl monomer having a carboxyl group and a monomer having a functional group reacting with the carboxyl group. The water-absorbent copolymer comprises a copolymer of acrylic acid and vinyl alcohol. The water-resistant graft copolymer and the water-absorbent copolymer are added at a ratio in parts by weight ranging from 20/80 to 80/20, preferably, from 30/70 to 70/30.

To obtain an air-conditioning apparatus that does not make a refrigerant circulate up to an indoor unit and further can achieve energy-saving. A refrigeration cycle is configured by connecting a compressor that pressurizes a refrigerant, a four-way valve that switches a circulation path of the refrigerant, a heat source side heat exchanger that performs heat exchange, expansion valves for pressure-adjusting the refrigerant, and a plurality of intermediate heat exchangers that performs heat exchange between the refrigerant and the heat medium to heat and cool the heat medium, with piping. A heat medium circuit is configured by connecting intermediate heat exchangers, pumps that pressurize the heat medium, and a plurality of use side heat exchangers that perform heat exchange between the heat medium and the air in the indoor space, with piping.

A drive system with small power loss in power conversion is provided. The drive system has an AC conversion device for converting commercial AC power from a commercial AC power supply and a DC conversion device. An AC power supply path for supplying power to discharge tubes, and a DC power supply path for supplying power to an image processing circuit or the like, are provided independently. The AC conversion device converts commercial AC power into converted AC power and gives the converted AC power to an AC drive device directly. Consequently, it is possible to reduce conversion steps for generating converted AC power and to reduce power loss that occurs in a conversion process. In particular, when power consumption of the discharge tubes is large, it is possible to reduce power loss in an entire liquid crystal display apparatus effectively by providing the AC conversion device.

A living body measurement system including a cerebral blood volume measurement unit for measuring a regional cerebral blood volume of a subject, an arterial pressure/heart rate measurement unit for measuring an arterial pressure and/or a heart rate of the subject, an analysis unit for analyzing signals measured by the cerebral blood volume measurement unit and the arterial pressure/heart rate measurement unit, an extraction unit for extracting information concerning a regional cerebral vascular state of the subject on the basis of an output of the analysis unit, and a display unit for displaying a measurement result measured by the cerebral blood volume measurement unit and/or the arterial pressure/heart rate measurement unit, an analysis result analyzed by the analysis unit, or an extraction result extracted by the extraction unit.
摘要:
A flat cable includes a signal line extending in a longitudinal direction, a thin dielectric sheet with which the signal line is coated and that has plasticity, a pair of spaced apart ground layers extending in the longitudinal direction and sandwiching the dielectric sheet in its thickness direction, and insulators that coat the pair of ground layers so that they are not exposed to the outside. The cross-sectional size of the signal line in a direction orthogonal to the longitudinal direction, the thickness and width of the dielectric sheet, and so forth are selected to obtain a predetermined characteristic impedance for the cable. Each of the pair of ground layers is sized so as to be substantially wider than the signal line.

An SAW device including a glass substrate, an LiNbO3 (LN) substrate, and an electrode. When a pitch of the electrode is &lgr;, a thickness of the LN substrate is H, and K equals to 2&pgr;/&lgr;, a product of K and H is at least 1.6 and at most 1.8. Accordingly, a SAW device which can advantageously reduced in size and provided with an enhanced temperature characteristic is obtained while ensuring high K2.
