Provided are: a retardation-increasing agent that has excellent compatibility and, when incorporated into a resin film, is capable of not only adjusting the thickness-direction phase difference toward a positive direction but also imparting the film with high retardation; a cellulose-based resin composition comprising the retardation-increasing agent; and a film that is obtained from the cellulose-based resin composition and has excellent optical properties. The retardation-increasing agent comprises a compound represented by the following Formula (1) or (2):  

Retardation-increasing agent, cellulose-based resin composition using same, and film

Provided are: a resin modifier which is capable of imparting a resin with excellent moisture resistance, dimensional stability and optical properties; and a resin composition including the same. The resin modifier contains a compound represented by the following Formula (1):

Disclosed is a stretched optical compensation film which is a phase difference film containing a cellulose-based resin and having excellent optical properties. The stretched optical compensation film of the present invention contains 0.5 to 30 parts by mass of a &#x3b2;-diketone compound represented by Formula (I) with respect to 100 parts by mass of the cellulose-based resin. Positions Rand Reach independently represent an alkyl group having 1 to 20 carbon atoms which is optionally substituted, an arylalkyl group having 7 to 20 carbon atoms which is optionally substituted or an aryl group having 6 to 20 carbon atoms which is optionally substituted. Position Rrepresents a hydrogen atom or an alkyl group having 1 to 10 carbon atoms. 

Stretched optical compensation film

Provided are a cellulose resin composition and cellulose resin film which are free from the problem of bleeding even when containing a plasticizer in a relatively large amount. The present invention relates to a cellulose resin composition obtained by adding (A) polyester plasticizer to a cellulose resin, wherein the aforementioned (A) polyester plasticizer is obtained by allowing a polybasic acid and a polyalcohol to react and 80 mol % or more of said polybasic acid is a succinic acid and an adipic acid. The present invention also relates to a cellulose resin film obtained from the cellulose-based resin composition.

A first housingis provided with a first and a second terminalsto be connected with a first and a second external antennas. A second housingis connected via a coaxial cablewith the first housing. The first housingincludes a switchconnected via a capacitorwith the coaxial cable, for selectively connecting one of the first and second terminalswhich provides higher receipt sensitivity on the basis of a switching signal and a DC power supplyconnected via an inductanceto the coaxial cable. The second housingincludes a radio circuitconnected via the capacitancewith the coaxial cable, for processing a radio signal to be transmitted, supplying the processed radio signals to the first or second internal antennaorand processing the received radio signal. A control circuitis connected via the inductanceto the coaxial cablefor outputting the switching signal on the basis of the received signal level by the external antenna and an inductance connected between the coaxial cable and a circuit required to be supplied with the DC power supply. Thus the radio signal is transmitted/received and the DC power is supplied via the coaxial cable

In a manufacture of a probe for a scattering type near-field microscope, there is provided a method of coating, with a high reproducibility, uniform metal particles efficiently inducing a surface enhanced Raman scattering. It has been adapted such that, in the probe for the scattering type near-field microscope, one part or all of the probe due to an interaction of at least an evanescent field is coated by metal particles which don't mutually adhere and have a particle diameter of 10 nm or larger and 50 nm or smaller in radius of curvature.

A device for providing a line of illumination in an optical reader, comprises an internally reflecting body having an elliptical reflecting surface joined to a part-cylindrical reflecting surface. A light source is disposed on one focal line of the elliptical surface, and a plate-like light guide has its light-receiving end disposed on the other focal line of the elliptical surface. One of the two focal lines of the elliptical surface is also the center of curvature of the part-cylindrical surface. The internal reflection and re-reflection of the light in the light guide ensures that the line of light emerging from the exit end of the light guide will be of uniform intensity throughout its length.
