A high speed imaging apparatus comprises an imaging sensor composed of a multiplicity of photoelectric converting elements which are two-dimensionally arrayed, the imaging sensor being sectioned into a plurality of blocks by effecting predetermined splitting in a vertical row direction and in a horizontal column direction and the blocks including photoelectric converting element groups, vertical and horizontal scanning circuit capable of parallel-reading of the photoelectric converting element groups of the respective blocks in vertical and horizontal direction, and a drive circuit for driving the vertical and horizontal scanning circuit so as to sequentially selecting one or plurality of the blocks within said imaging sensor which are then read and scanned. The imaging apparatus may further comprise an operation sensor for detecting a moving direction of an object, a control unit for calculating the blocks to be selected and a reading order of the selected blocks in response to a signal from the operation sensor, and a block selection address generation circuit through which an output signal from the control unit is inputted to the drive circuit so as to sequentially change over the blocks of the imaging sensor in accordance with the moving direction of the object.

A musical tone visualizing apparatus includes at least an image memory for storing plural images relating to players and/or musical instruments of an orchestra, a display unit for displaying the images on a display screen thereof and a display control circuit for controlling the display unit so that displayed images can be varied in response to an inputted musical tone signal or inputted performance information outputted from an electronic musical instrument, for example. Hence, it is possible to move the players and musical instruments in response to performance of the electronic musical instrument, and it is also possible to selectively enlarge one display image of the player and musical instrument whose tone volume is the largest. Thus, the displayed images can be automatically varied in response to the performance of the electronic musical instrument.

A machine tool comprising a spindle head, a tool magazine, and an arm, the arm being secured to the spindle head, the arm having gripping members for holding a tool holder. When a workpiece is machined, the arm in which gripping members are opened is placed near the spindle. As soon as machining is completed, the grip members are closed so as to hold the tool holder set into the spindle. The end face of the spindle and the end face of the tool magazine stand at different levels when the spindle head is located in tool changing position. When a used tool is returned to the tool magazine, the arm operates in the following steps: first, the arm grips the used tool set into the spindle; second, the arm is moved so as to draw the tool from the spindle; and third, the arm is swiveled so as to return the tool to the tool magazine.
摘要:
An electronic musical instrument using FM tone synthesis technology produces a musical tone signal e(t) expressed ase(t)=A.multidot.sin[.omega.ct+I.multidot.sin .omega.mt],where A I, .omega.ct and .omega.mt represent an amplitude information, a modulation index information, a carrier frequency information and a modulation frequency information, respectively. The carrier frequency information .omega.ct and the modulation frequency information .omega.mt are related to a pitch of a depressed key of the electronic musical instrument. A modulation ratio controller is further provided in the instrument. The modulation ratio controller varies the modulation ratio .omega.c:.omega.m of the carrier frequency information .omega.ct to the modulation frequency information .omega.mt in accordance with the pitch of the depressed key. Such a musical tone having different harmonic constructions according to the tone pitches as that of a pipe organ is implemented by this variation of the modulation ratio.

A receiver has a program reserving function in which a reserved time previously stored in a program reserving memory is continuously compared with outputs produced by a clock circuit in response to actual time, and accordingly when the actual time coincides with the reserved time, the receiver automatically receives a wave corresponding to a preset number previously stored in the program reserving memory together with the reserved time. The receiver is characterized particularly in that there are further provided a program button for allowing the time adjusting buttons to serve as program input buttons and a memory button for causing the memory to store the data put in by the time adjusting buttons. With this arrangement, the time adjusting buttons are switched to be reserved data input buttons by means of the program button and returned to be buttons for adjusting time means of by the memory button.

摘要:
An electronic musical instrument is of a type wherein musical tone waveforms are stored in a memory as their sampled amplitudes and sequentially and repetitively read out to constitute tone waveforms. A key depression brings forth key code in a digital representation. This key code is used for reading out frequency information from a frequency information memory. The frequency informaton is accumulated to make an address signal for reading out the waveform memory. The read out waveform is reproduced as a musical tone through a tone-color and volume control circuit. This tone-color and volume control circuit is controlled keyboard by keyboard.The key code produced upon depression of the key contains a signal representing the kind of the keyboard to which the depressed key belongs. This signal is applied to a conversion circuit and converted to a signal representative of a different kind of keyboard. The output signal of the conversion circuit operates the tone-color and volume control circuit in a manner corresponding to the keyboard designated by the converted signal while the original signal representing the kind of the keyboard of the depressed key is applied directly to the tone-color and volume control circuit to operate it in a manner corresponding to the keybord of the depressed key. The manner of conversion of the signal representing the keyboard can be selected as desired. There is disclosed an example of a coupler effect between the upper and lower keyboard which can be produced by converting a signal for the upper keyboard to a signal for the lower keyboard while directly using the upper keyboard signal. Also disclosed is an example of a coupler effect between the lower keyboard and the pedal keyboard produced by converting a signal for the lower keyboard to a signal for the pedal keyboard while directly using the lower keyboard signal.
