IPC: G10K9/12
Filed: 1990-03-27
Abstract: PURPOSE:To improve sound quality by including a prescribed central frequency and plural various frequencies close to the central frequency in a signal to be supplied to an electric acoustic transformer. CONSTITUTION:In a circuit 10 equipped with an operational amplifier 20, diodes 24 and 30 and variable resistors 26 and 28, a rectangular wave A is obtained to be repeated at the fixed cycle of a voltage Va, and a piezoelectric element 36 driving transistor 40 is driven through a coupled transformer 32 and a switching transistor 34. This element 36 is oscillated at a resonance frequency fo. When the piezoelectric element 36 is fixed to a resonance box, the frequency fo is a natural oscillation frequency as a whole including the resonance box. The rectangular wafe A is developed to the class only of an odd-number item and superimposed to the frequency fo, and therefore, the frequency fo can be divided into frequency components to be dispersed at prescribed periodic intervals in the center of the frequency fo. Then, the more the cmponent is away from the fo, the more the size of the component is decreased according to the coefficient size of the class and the frequency characteristic of the piezoelectric element. The frequency from 3 to 5 at the center of the frequency fo is mainly contributed to the tone and the stimulation of the sound quality is weakened. Then, the tone is made mellifluous.

Abstract: PURPOSE:To enhance the function of the recording and reproducing characteristics of magneto-optical recording by increasing boundary magnetic wall energy in exchange bonded multilayered films and providing the operations, such as transfer, inversion and deformation, of magnetic domains with dependency on the magnetic domains. CONSTITUTION:A protective layer (SiN, 80nm), a reproducing layer 9 (Ggd25Fe50Co25, 50nm), a cutting layer 10 (Tb25Dy10Fe65, 20nm) and a protective layer 8 (SiN, 80nm) are successively formed by a sputtering method on a substrate 7 formed with grooves on a glass disk. This disk is subjected to recording by changing the magnetic domain diameter to 0.4 to 5mum. The reproduced outputs of the case the magnetic super- resolution is not generated in all the magnetic domain diameters, the case the magnetic super-resolution is generated in all the magnetic domain diameters and the case the magnetic super-resolution is generated in the magnetic domain diameter <=0.8mum are investigated. Consequently, the degradation in the reproduced signal outputs in the large magnetic domains is suppressed when the generation of the magnetic super- resolution is suppressed to the magnetic domain diameter or below. On the other hand, the operations, such as transfer, inversion and deformation, of the magnetic domains are provided with dependency on the magnetic domains if the boundary wall energy is increased.

Filed: 1989-03-27
Abstract: PURPOSE:To obtain a semiconductor laser which realizes the reduction of ineffectual current and a high output by a method wherein the impurity concentration of a first conductivity type second lower cladding layer directly under an active region is selectively increased. CONSTITUTION:The impurity in a first conductivity type first lower cladding layer 2 is introduced into a first conductivity type second lower cladding layer 3 through the contact region between the first conductivity first lower cladding layer 2 and the first conductivity type second lower cladding layer 3 by thermal diffusion to form an impurity region 9 which is formed by increasing the impurity concentration of the first conductivity type second lower cladding layer 3 directly under an active region 8 selectively. In other words, the impurity concentration of the first conductivity type second lower cladding layer 3 is selectively increased. With this constitution, a reactive current which does not contribute to an oscillation can be reduced and, not only light output vs. current characteristics at the time of a high output operation can be improved but also power consumption can be saved by the reduction of a threshold current and the improvement of a light emission efficiency, so that the life of a laser device can be improved.
