A rotatively-operated electronic component with a push switch includes an attachment base plate. A rotatively-operated electronic component portion supported on the attachment base plate has a rotatable operation knob. An electric signal can be generated in response to rotation of the operation knob. The rotatively-operated electronic component portion can move relative to the attachment base plate by application of a force to the operation knob. A push switch portion is supported on the attachment base plate. The push switch portion is actuated in response to movement of the rotatively-operated electronic component portion relative to the attachment base plate by the application of the force to the operation knob.

The present invention presents a novel fluorescent solvatochromic dye that (1) has an ionic terminal that makes it easier to use in a hydrophilic surface or in polar solvents, (2) can be efficiently excited by commonly used Argon lasers (488 nm), (3) shifts the wavelength of emitted light according to the change of polarity, and (4) can effectively stain living tissues such as cells and the like.A pyridinium group was introduced to the electron attracting group of the neutral fluorescent solvatochromic dye (Japanese Patent Application Public Disclosure No. 20008-291210 A) displaying an excellent emission wavelength response and synthesized a fluorescent solvatochromic dye. Then it was found that the fluorescence wavelength of the fluorescent solvatochromic dye changed extensively when the polarity changed on a hydrophilic surface and that the fluorescent solvatochromic dye, when altered to a cationic form, stained cell membranes and could be used to observe the behavior thereof.

In response to a voice request from a facility judgment means which judges the location of such a facility from the current position selected in advance based on the current position and map data, the voice guidance generated by guidance synchronizing means is converted by stereophonic or three dimensional signal processing means into a stereophonic or three dimensional sound field signal, and outputted to at least two or more speakers which generate a stereophonic or three dimensional sound field reproducing space corresponding to the left and right external ears of a listener. The distance to, and the direction of, the facility that has been selected in advance are informed by the movement of an image of a stereophonic or three dimensional sound with rich presence.

A method and apparatus to determine the constituent ingredients in a sample by a spectroscopic procedure is disclosed. A Fourier transformation infrared spectrometer can secure data of a power spectrum of a sample and data of a power spectrum of a reference. A absorption spectrum of the sample from this respective data can be determined. A set of wave number points across the absorption spectrum of the sample that exhibit a predetermined linear characteristic can be selected and the absorption spectrum values corresponding to the set of wave number points can be used to calculate the concentrations of the constituent ingredients. A plurality of sets of wave number points can also be predetermined for a specific sample and limit values can be stored and compared to pick the most desirable set of wave number points for calculating the concentration of the constituent ingredients.

A vehicle-mounted three dimensional sound signal reproducing•silencing unit includes at least two speakers disposed for each of seats to be occupied by listeners so as to generate a three dimensional sound field space in a region inclusive of left and right external ears of each of the listeners, and three dimensional signal processing means for converting an output signal from a sound source into a three dimensional sound field signal for supplying it to each of the speakers, thereby reproducing a three dimensional sound field with rich presence for each of the seats. The unit also includes antiphase signal generating means for supplying a silencing signal to the three dimensional signal processing means, thereby silencing sounds for each of the seats without giving an effect on the other seats.
