Abstract: When data are to be recorded on a recording medium having imparted thereto a medium ID that is identification information unique to the recording medium, an additional ID related to the medium ID is generated on the basis of the medium ID. Then, the data are encrypted and recorded on the medium along with the additional ID. In reproduction, the medium ID and the additional ID attached to the data are read out from the medium, and then compared to determine whether both of the medium ID and additional ID meet a predetermined matching condition. When the additional ID attached to the data has been determined as meeting the predetermined matching condition, the data is judged to be reproducible data. In this manner, it is possible to promptly determined whether or not the data recorded on the medium are fairly-recorded data, which can effectively prevent unfair use of the data.

Abstract: A display 21 for setting atone control parameter is disposed on an operation panel of an electronic musical instrument. Function and subfunction operator groups 23, 24 are arranged in parallel in two rows along a longer side of display 21. Function operator group 23 corresponds to each function in the first hierarchy, and subfunction operator group 24 corresponds to each subfunction in the second hierarchy that is designated for each function in the first hierarchy. Display 21 displays a tone control parameter that is to be set by the operation of a parameter setting operator group 25 and the characters representing each function and each subfunction of the function and subfunction operator groups 23, 24. By operation of each operator group 23, 24, the functions and the subfunctions are switched hierarchy by hierarchy, whereby a desired tone control parameter can be easily set to be a desired value or can be easily changed.

Abstract: In a musical tone control apparatus, musical tones to be generated are controlled according to musical tone control parameters which include an envelope that has been extracted and processed. The range of variation of the extracted envelope may be limited within a predetermined range, so that the musical tones are controlled according to the thus limited envelope. A key-on event of the input signal may be detected, and the timing of delivery of the processed envelope may be changed according to a length of time that elapses from a point of time when the key-on event is detected. The velocity of the input signal may also be detected, so that the musical tones are controlled according to the musical tone control parameters including one or more parameters altered according to the detected velocity and processed envelope.

Abstract: A performance data generation apparatus generates performance data for controlling the tone generation condition of a tone to be generated based on a string vibration signal obtained from the string vibration of a stringed instrument. The performance data generation apparatus includes an operation member for selecting a predetermined performance operation mode and a control device responsive to the operation member. When the predetermined performance operation mode is selected by operating the operation member, the control device does not output note-on data or note-off data among performance data that is generated based on the string vibration signal, and outputs specified performance data other than the note-on data and the note-off data.

Abstract: An automatic performance section and an effect imparting section or (and) a pitch measuring section are provided in combination within a single device, and the operations of these sections are collectively controlled by a processor. To an external sound signal input from outside the device, the effect imparting section imparts an effect designated by designating data. For tuning purposes, the pitch measuring section detects zero-cross points of the external sound signal to measure the pitch of the signal. Under the control of the processor, the automatic performance section, which has automatic performance data and change data stored therein, under the control of the processor, reads out the performance data to perform an automatic performance process and also reads out the change data for changing the designating data to thereby change an effect to be imparted.

Abstract: An optical remote controller includes a movable infrared ray transmitter, a plurality of light receiving modules, and a received light signal selector for selecting the earliest sensed one from the light signals received by the light receiving modules. The signal selector includes a clock signal generator, first to third mask signal generators to generate invalidation signals, received light signal mask circuits to invalidate received signals, a mask release signal generator to measure an invalidation time period, and an encoder to sense termination of each unit of transmission information. A camera is attached rotatably in vertical and horizontal directions on a fixed support plate. The support plate includes a plurality of infrared ray receiving elements. According to a moving command of an optical remote control signal received by the elements, an optical remote controller vertically and horizontally drives the camera and directs the camera to the arrival direction of the remote control signal.

Abstract: A swivel joint for connecting fluid pipes includes a plurality of elements placed one upon another. Each element includes a cylindrical stationary portion and a cylindrical rotatable portion surrounding the stationary portion and supported rotatably thereon by a pair of vertically spaced apart sliding bearings. The two portions define therebetween an annular fluid passage having a fluid inlet to which a pipe is connected and a fluid outlet to which another pipe is connected. The rotatable portion has a pair of inclined edge surfaces. Each bearing has an inclined edge surface which is complementary to one of the inclined edge surfaces of the rotatable portion and which cooperates therewith to align the axis of rotation of the rotatable portion with the center of the stationary portion. The two portions have therebetween a clearance for absorbing any positional variation by thermal expansion thereof relative to each other.
