摘要： The apparatus produces glide and portamento in an electronic musical instrument in which the generated tone is proportional to a current frequency number. A time varying fractional frequency number is established that increases or decreases in value during glide or portamento production. The current frequency number is modified by increments that correspond to the fractional frequency number values, so that the generated tone glides to the nominal pitch, or so that during portamento the generated tone slides from the pitch of the note previously produced to the nominal frequency of the new note.

摘要： In a computor organ of the type wherein a musical waveshape is synthesized by computing in real time the amplitude contributions of the constituent Fourier components and summing these to obtain each waveshape sample point amplitude, the tonal quality or voice of the produced note is established by a set of harmonic coefficients that specify the relative amplitude of each Fourier component. Herein circuitry is disclosed for modifying the harmonic coefficient values to accomplish transient voice insertion including ''''chiff'''' and percussive transients, to modulate the harmonic content as a function of time during attack and decay, and to facilitate the external insertion of additional voices for the instrument.

摘要： A plurality of signal delay lines are provided each constituted by a number of bucket brigade devices, the number being different from one line to another and consequently the delaying time being different accordingly from one line to another. An audio signal is inputted to the respective delay lines and outputs from the delay lines are admixed to be a reverberated output signal. The delay times are variable in accordance with a transfer clock frequency applied to the bucket brigade devices.

摘要： An electronic musical instrument is capable of modulation controlling at least one of the pitch frequency, tone color and volume envelope of a second keyboard section tone signal by a tone signal obtained by operating any key on the first keyboard section. To control the frequency, tone color and volume envelope of the second keyboard section tone signal, a voltage controlled oscillator, voltage controlled filter and voltage controlled amplifier can be used. The first keyboard section tone signal may be frequency divided and/or waveform converted so as to control the second keyboard section tone signal.

摘要： Herein disclosed is a saw apparatus having circular saw blades which are independently axially movable on a rotary shaft supporting the blades for cutting a board to sections along markings applied on the face or faces of the board. The markings are sensed by a scanning arrangement and signals are produced when the scanning arrangement detects the markings. The saw blades are shifted to positions specified by these signals which represent the locations of the individual markings.

摘要： A reference frequency signal is prepared by a fixed frequency oscillator or by multiplying the IF frequency. A receiving frequency representing signal is obtained as an output of the RF amplifier or that of the local oscillator. The two signals are mixed to produce a beat frequency signal, which is converted by a frequency detector into a d.c. voltage or current, which in turn is applied to a meter. The meter carries a scale marked in frequencies, the pointer indicating the receiving frequency.

摘要： A waveform memory memorises a particular desired waveform as a sampled values at dotted time points. A ring counter driven by a voltage controlled oscillator reads the waveform memory to produce the memorized waveform signal. Ring counter cycle frequency fx is divided into fx/2n. An input signal frequency fi is divided into fi/2m. These fx/2n and fi/2m are compared with each other by a phase difference detector, whose output is applied back to the voltage controlled oscillator to bring the oscillator frequency to such a value that fx/2n Fi/2m, i.e. fx (n/m) fi. In this way, an output signal of a desired waveform and having a frequency fx which is of a ratio of any rational number n/m to the input signal frequency fi can be obtained.

摘要： A novel auxiliary ski for physically handicapped persons, comprising a ski runner having a through hole therein, a pair of guide plate members erected from the ski runner, and a pole rotatably supported between the guide plate members. Each guide plate member has a pair of pole locking slots formed at two different positions in the lengthwise direction of the pole, and a guiding slot connecting the pair of pole locking slots. The pole is lockable at one of the pole locking slots and is movable, along the guiding slot, in its lengthwise direction with respect to the ski runner and further lockable at the other of the pole locking slots, whereby the lowermost tip of the pole can either be retained within the through hole of the ski runner or be protruded through said hole down to below the ski runner.

摘要： Several bucket brigade devices respectively constituting signal delay paths are supplied with one common sound signal obtained from one electric musical instrument such as an electronic organ or electric guitar or are separately supplied with different sound signals derived from one or more electrical musical instruments. Each of the bucket brigade devices receives the sound source signal, transmits the signal therethrough with a delay which is in accordance with the clock pulse applied thereto from a clock pulse oscillator and gives out a time-delayed signal. The delaying time is determined by the clock pulse frequency of 40 kHz to 120 kHz which is controlled by a plurality first low frequency signals having a frequency of about 0.5 to 3 Hz and a second low frequency signal having a frequency about 5 to 12 times that of the former signal and a voltage level equal to about 1/3 to 1/5 of that of the former signal. The first low frequency signals applied to the respective clock pulse oscillators are different in phase from one another. Sound signals from the bucket brigade devices are conducted through amplifiers to one or more loudspeakers, thereby reproducing musical sounds from the loudspeakers with a unique orchestra or chorus effect.
摘要翻译： 分别构成信号延迟路径的多个桶旅装置被提供有从诸如电子琴或电吉他的一个电乐器获得的一个公共声音信号，或者分别提供有从一个或多个电气乐器导出的不同声音信号。 每个斗式装置接收声源信号，通过与时钟脉冲振荡器施加的时钟脉冲相对应的延迟来发送信号，并给出时间延迟信号。 延迟时间由40kHz至120kHz的时钟脉冲频率确定，该时钟脉冲频率由具有约0.5至3Hz频率的多个第一低频信号控制，第二低频信号的频率约为5至12倍，频率约为5至12倍。 并且电压电平等于前一个信号的约1/3至1/5。 施加到各个时钟脉冲振荡器的第一低频信号的相位彼此不同。 来自铲斗旅装置的声音信号通过放大器传导到一个或多个扬声器，从而以独特的乐团或合唱效果从扬声器再现音乐声音。
