Abstract:
An electronic musical instrument, which enables a player easily to select by operating a switch any of a plural number of tone colors from a large number of tone colors originally preset in the musical instrument in a form of tone color data stored in a memory unit, to thereby more easily carry out a performance within a broadened range of performance techniques.
Abstract:
A data-recording device wherein a plurality of tracks are concentrically provided on the recording surface of a rotatable magnetic recording medium. A plurality of sector-starting positions are arranged on the respective tracks at a given circumferential interval to detect the extent to which the magnetic recording medium has been rotated, and one sector-starting position among the sector-starting positions of the respective tracks is used as a point at which the writing or reading of data is to be commenced. A circumferential angular interval between a sector-starting position provided on a given track to be used as a data write-read starting point and a similar sector-starting position provided on a track adjacent to said given track to be used as a data write-read starting point is so defined as to give a magnetic head a sufficient length of time to be shifted from said given track to the adjacent track in the time of rotating of a magnetic recording medium being rotated through the above-mentioned circumferential angular interval.
Abstract:
A coin-delivering device which comprises a plurality of coin holders equiangularly arranged in a circumferential direction respectively to hold coins of different denominations and a plurality of coin receptacles similarly equiangularly arranged in a circumferential direction set below the coin outlets of the respective coin holder at a prescribed spacing, and wherein a coin placed on the coin receptacle is flipped out by an arm rotated by a rotary shaft, and the coin is or is not delivered as a function of the coin-flipping arm being selectively moved upward or downward by a control signal.
Abstract:
The device includes indicator elements capable of sequentially indicating the output of a counter in the forming of a plurality of time bands; an operation command signal distributor capable of generating an output for the performance of an operation having any given object corresponding to one selected from said indicator elements; and operating members for optionally selecting and causing the generation of command signals for the performance of an operation having any given object. The operation command signal distributor is enabled by an operating member when a specified indication element is lighted, to thereby command a selected operation having any given object, the command generation being a function of which indicator element is lighted.
Abstract:
A tabulation control system including a tab position memory shift register for memorizing tab-set position signals representing summed up values from the first position in a range in which tab setting operations are possible. A buffer register is connected to receive tab-set position signals in response to shift signals according to tab commands, a printing head position counter for counting the total and number of shifts of a printing head from the first position is provided. Also provided is coincidence detector which compares the output from the buffer register with the output of the counter and stops the printing head when these outputs coincide with each other.
Abstract:
A global timepiece provided with a counting circuit for electronically counting at least seconds, minutes, hours, days and months upon receipt of a signal from a pulse oscillator and particularly a control circuit for advancing a date from the last day of a given month to the first day of the following month according to a calendar, which comprises a date-counting circuit for counting a day by an advance pulse generated per day; a day-detecting circuit for detecting a count of "1" representing the first day of a calendar month which has been counted by the day-counting circuit; a circuit for setting the count made by said day-counting circuit at a "0" upon receipt of an output signal denoting a count of "1" which has been detected by the day-detecting circuit and also a time correction-instructing signal for backdating a date one day according to an instruction based on a time difference occurring between any two districts in indicating the count of "0" made by the day-counting circuit to represent the last day of each preceding month in the form of a specific notation.
Abstract:
An electronic timepiece comprises a first time counting circuit including a time counter and adapted to count reference clock signals of an oscillator as time data at all times, and a time interval counting circuit provided independently of the time counting circuit and adapted to perform the function of a stopwatch based on a time count start instruction and time count stop instruction. The timepiece further includes a control circuit in which a minute/hour data and a date data are selectively displayed by the operation of a first switch on a digital type indicator and when the timepiece functions as a stopwatch a time interval data is displayed by the operation of a second switch on the indicator based on the time count start instruction and time count stop instruction. The control circuit has additional functions that, while the timepiece functions as a stopwatch, a normal minute/hour data from the time counting circuit can be switched by the operation of the first switch to a minute/hour time interval data (stopwatch) for display on the indicator and after display of the minute/hour time interval data a time interval data corresponding to a second or less can be displayed by the operation of the first switch on the indicator.
Abstract:
A device for controlling the handling of data which comprises a main memory for storing a large number of record data items in a state marked off by record-positioning codes, said respective record data items being formed of series-arranged word data items of variable word length, each containing a plurality (including one) of characters marked off by word-positioning codes, wherein a processing memory is a matrix type formed of columns containing words each having a certain number of characters falling within a specified range and a plurality of rows, and designed to store at least one record data item read out of the main memory; characters constituting the foremost word data item of a record data item read out of the main memory are written with shifting in a given row of the matrix memory, starting with the first character of said word data item; upon detection of a word positioning code immediately following said foremost word data item, the succeeding word data item is written in a row adjacent to said given row of the matrix memory; and readout of data items from the main memory to each row of the matrix memory is brought to an end when a record-positioning code following the last word data item of each row is detected.
Abstract:
A digital display type timepiece has a 2-digit decimal numerical figure display section divided in a manner to correspond to an hour and a minute display with a dividing display mark therebetween. A month and date-of-month display can also be made, by switching, on the same decimal display section. A time display is effected on the decimal display section by count outputs of time counters adapted to be driven by reference signals of an oscillator. During the time display, the display mark is flashed in a predetermined second cycle by the reference signal of the oscillator. The date display is made on the same display section by count outputs of date-of-month counters adapted to be driven by carry signals of the time counters. When switching is made from the time display to the date display, the display mark is correspondingly switched into a state different from the flashed state.
