A rewritable thermosensitive recording medium having a recording layer, the transparency of which reversibly changes depending on the temperature thereof. Further, the recording layer contains a matrix material and an organic low-molecular-weight material dispersed in the matrix material as main components thereof. Moreover, an alicyclic dicarboxylic acid compound is added to the organic low-molecular-weight material dispersed in the matrix material. Furthermore, by adding the alicyclic dicarboxylic acid compound to the organic low-molecular-weight material, the eutectic point of the organic low-molecular-weight material and the alicyclic dicarboxylic acid compound becomes higher than the melting point of the organic low-molecular-weight material. Additionally, in spite of the fact that the amount of the alicyclic dicarboxylic acid compound to be added to the organic low-molecular-weight material is small, the difference between the eutectic point of the organic low-molecular-weight material and the alicyclic dicarboxylic acid compound and the melting point of the organic low-molecular-weight material is much larger than those obtained in cases of conventional recording materials. Consequently, the range of temperature, to which the recording layer should be heated for changing a state thereof from an opaque state to a transparent state, can be considerably enlarged without reducing the opacity of the recording layer.

According to the present invention, there is provided a laminated composite including an optical layer having a light reflectivity, and a latent image formation layer containing a liquid crystalline polymer material and provided on one of major surfaces of the optical layer, wherein the latent image formation layer includes at least one oriented portion in an orientation state and at least one non-oriented portion in a non-orientation state, and the oriented and non-oriented portions constitute a latent image which is unrecognizable by a direct visual observation and recognizable by a visual observation through a polarizing member. Also, according to the present invention, there is provided an information recording medium and a member of imparting a forgery-preventing characteristic including such a latent image formation layer.

A controllable muffler system is sued for use with an engine that produces a power by burning fuel. The system comprises a first passage section extending from the engine for having an exhaust gas of the engine flow therethrough. The first passage section has a catalytic converter mounted thereon. The system further comprises a dual passage section including second and third passage sections which extend separately from an end of the first passage section. The second passage has a control valve for controlling the flow rate of the exhaust gas flowing therethrough. The system further comprises a fourth passage section extending from respective ends of the second and third passage sections to the open air. The fourth passage section has a rear muffler mounted thereon. The system further comprises a control unit which controls the control valve of the second passage section in accordance with an operation condition of the engine.

Green beany flavors and odors characteristic of soybean can be removed to a satisfactory extent from a textured soy protein by a method comprising (i) the first step of treatment wherein the soy protein is retained at a temperature of from 80.degree. to 145.degree. C. for a suitable period of time while the water content of said soy protein is maintained at a predetermined value, and (ii) the second step of treatment wherein said moistened soy protein treated in the first step is kept in contact with a flow of superheated steam at a temperature of from 105.degree. to 160.degree. C.
