摘要： The speed of an input speech is changed without any change of the pitch of the input speech. Raw data of a speech are stored so that the speed of the speech can be modulated continuously on the basis of the raw data of the speech. In the speech speed conversion method, a speech speed conversion process for the input speech is carried out in a period designated when speech speed conversion is needed, which the speech speed conversion is not carried out in the other period. Further, in the speech speed conversion apparatus having a unit for inputting a speech, a speech speed conversion unit for changing the speed of the input speech, and a unit for supplying the output of the speech speed conversion unit as an output speech to listener's ears, the apparatus further includes a speech speed conversion switch, and a unit for outputting a speech while changing the speech speed of the input speech in a period in which the speech speed conversion switch is turned on, but for outputting a speech without any change of the input speech in the other period in which the speech speed conversion switch is turned off.

摘要： A rotary magnetic head device and a rotary transformer used therefor are disclosed. A pair of througholes, through which the starting extremity and the ending extremity of each of a plurality of coil conductors disposed on the rotor core and the stator core constituting the rotary transformer are led to the respective rear surfaces, are linked by a linking slit. Alternatively one throughhole, through which both the starting extremity and the ending extremity of each of the coil conductors are led, is divided into two throughholes by disposing therein a non-magnetic partitioning member having a thermal expansion coefficient close to that of the magnetic body within a region of 15%. In this way, the two throughholes behave magnetically as if the starting extremity and the ending extremity of each of coil conductors passed through one throughhole, so that magnetic field components produced at the starting portion and the ending portion cancel each other and that the coupling coefficient between the rotor core and the stator core is increased.

摘要： A rotary magnetic head cylinder device for use in a helical-scanning system video tape recorder has a projection provided on a tape running race of a stationary lower cylinder near a location at which a magnetic tape leaves from the lower cylinder. The projection is preferably integral with the tape running race and has a small area which is defined by a shoulder circumferentially extending identically with a tape guide shoulder contouring the lower edge of the tape running race and which spreads perpendicularly to the tape running race, and an upper surface coplanar with the top face of the lower cylinder, and a height defined by a protruded length radially outwardly toward the outer circumferential surface of the lower cylinder. The projection serves to reduce vibrations of the magnetic tape generated when the video head carried by the rotary upper cylinder leaves from the magnetic tape.

The insulating layer is removed from the coil at portions corresponding to starting and terminating ends of the winding thereof. The insulating layer is bonded to the bottoms of the grooves. Through holes are formed in the core at positions corresponding to the starting and terminating end portions of the windings of the coil. Conductive junction members extend in the through holes and are electrically connected to the starting and terminating end portions of the windings of the coils to transmit signals to and from the magnetic heads.

摘要： A hydrodynamic grooved bearing device in which a shaft is inserted into a hole formed in a bearing housing and one of the shaft and bearing housing is rotated, thereby the rotated member being supported includes a plurality of grooves formed on the shaft or an inner peripheral surface of the bearing housing for generating a dynamic pressure of fluid filled between the shaft and the bearing housing. The plurality of grooves are arranged side by side with a substantially certain pitch in a direction of rotation. Each of the grooves comprises a pair of groove portions slanted relative to the direction of rotation such that a distance between the pair of groove portions becomes narrower towards the direction of rotation and a connecting groove portion connecting the narrowest distance between the slanted groove portions. The connecting groove portion is extended in a direction substantially perpendicular to the direction of rotation. The provision of the dynamic pressure generating grooves enables a high bearing load and a stable bearing performance with a minimum degree of whirling compared with conventional V-grooved bearing.
