摘要： A circuit is provided for emphasizing or suppressing both a frequency corresponding to an upper sideband and a frequency corresponding to a lower sideband with respect to a frequency corresponding to the carrier of a frequency-modulated signal in equalizing the frequency-modulated signal reproduced from the recording medium. With this arrangement, it is possible to effectively compensate for the nonlinearity of a magnetic recording and reproducing system even in the case of a wide deviation. Also, the envelope levels of the portions of a frequency-modulated signal which are formed by frequency-modulating portions of a signal whose levels differ from each other, are extracted to adjust the equalizing characteristics of the equalizing circuit in accordance with the difference between the levels, whereby variations in the characteristics of a reproduction equalizing circuit due to variations with time can be appropriately compensated for.

摘要： A digital information restoring device is arranged to detect time between level transition points of a digital signal which indicates digital information by means of variations in its period, output the resultant period data, calculate an average value of at least two period data among the output period data, and compare the average value with the aforesaid period data, and restore the digital information. The digital information restoring device is, therefore, capable of restoring the digital information at a high speed without using a high-speed PLL circuit or the like. The digital information restoring device may also be arranged to perform time-axis expansion of only part of the received period data, and input the resultant period data to a computing circuit to restore the digital information.

摘要： In the photocathode, an underlayer made of a crystalline material containing La2O3 is provided between a supporting substrate and a photoelectron emission layer, and is in contact with the photoelectron emission layer. Therefore, for example, at the time of heat treatment in a manufacturing process of the photocathode, dispersion to the supporting substrate side of an alkali metal contained in the photoelectron emission layer is suppressed. Further, it is assumed that this underlayer functions so as to reverse the direction of, out of photoelectrons e− generated within the photoelectron emission layer, photoelectrons traveling toward the supporting substrate side to the side opposite thereto.

摘要： Provided is a process for producing a dyed plastic lens in accordance with which in accordance with which deformation and change in the color of the plastic lens can be suppressed and a plastic lens having a refractive index of 1.7 or greater and, in particular, a refractive index of 1.7 to 1.8, can be preferably dyed uniformly to a great density without unevenness. Specifically, the process for producing a dyed plastic lens comprises: Step (1) of coating a substrate comprising glass with a sublimation dye; Step (2) of, after placing a plastic lens in a manner such that a face for dyeing of the plastic lens and a face of the substrate coated with the sublimation dye face each other, sublimating the sublimation dye coating the substrate obtained in Step (1) by heating the substrate under a degree of vacuum of 1×104 Pa or smaller to attach the sublimated dye to the face for dyeing of the lens without permeation into the lens; and Step (3) of allowing the sublimation dye attached to the plastic lens to permeate into the lens by treatment of heating the plastic lens having the attached sublimation dye obtained in Step (2). The plastic lens becomes likely to be dyed uniformly without unevenness to a great density by using a plastic lens whose face for dyeing is subjected to treatment with plasma.

摘要： Side plates, constituting side surfaces of a speaker cabinet, each comprise a base member having a plurality of grooves formed in its outer surface (obverse surface) region at predetermined intervals, and a decorative plate adhesively bonded to the outer surface of the base member, in a laminated fashion, so as to cover the grooves. The laminated base member and decorative plate are pressed and curved, via upper and lower molds, so as to provide a smooth, convexlycurved outer surface. The grooves are adhesively bonded along their opening edges to the inner surface of the decorative plate, so that the opening edges of each of the grooves will not move toward or away from each other when external force is applied to the side plate.
