Abstract:
An electronic timepiece has an optical display device for displaying time in digits and an alarm time indicator for setting an alarm time in terms of the position of a pointer. The position of the pointer is electronically detected and is applied as alarm time data to a time counting circuit. When current time is coincident with the alarm time set by the pointer, the alarm is given.
Abstract:
An electronic stop watch includes a time counter circuit starting to count reference clock pulses in response to a starting signal and a digital display arrangement having a predetermined number of display sections to display the time counted or measured by the time counter circuit.A specified count detection circuit is provided to detect that a count of the time counter circuit has reached a specified value which can be displayed by the display sections of the display arrangement. A detection output signal from the detection circuit serves as a display changeover command signal to control count signals which are supplied from the time counter circuit to the display arrangement so that the display arrangement can display time, according to the count of the time counter circuit, in large units of time, for example, in "hours and minutes", instead of small units of time, for example, in "minutes and seconds", after a detection signal has been produced from the detection circuit.

Abstract:
A data processing control apparatus comprises a main memory for storing a plurality of record data serially arranged with a record positioning code between the record data, each record data including a plurality of word data serially arranged with a word positioning code between the word data, the word data each including at least one character data; and a processing memory means having a row/column matrix which is address designated by the outputs of row and column counters for permitting each word data in the record data to be stored in its address. A specific row of a heading column in the matrix in the processing memory means is address designated to permit the address position data in this row to be sequentially shifted in a row direction. Specific codes, each written in an address position following a final character data, in the word data are counted by a counter while an address shift is effected in a column direction from an address position in the specific row. A word order memory is adapted to beforehand store a numerical value corresponding to the order of a word data to be selected from the record data and a coincidence circuit is adapted to detect a coincidence between the number of specific codes counted by the counter and a numerical value stored in the word order memory. When a coincidence output is generated from the coincidence circuit a data readout from the main memory to the processing memory means is inhibited by the coincidence output of the coincidence circuit and only a word data corresponding to a selected word order is delivered to the data processing memory.
Abstract:
An electronic timepiece uses a dynamic type shift register, as a time count circuit, which has a plurality of memory sections corresponding to an equal number of time count units and a cycle number memory section arranged such that it is preceded by said plurality of memory sections. An adder and shift memory unit are serially connected to the shift register to provide a shift circulation circuit and the shift circulation is effected by an oscillation signal from a reference oscillator. The adder adds [1] to the contents of the cycle number memory section for each data shift cycle of the shift register. Each time the count value of the cycle number memory section reaches a predetermined cycle number, the count value of a smallest time unit is counted one step. In this way, a carry is propagated to the subsequent large time unit memory sections according to the data shift circulation cycle of the shift register. A memory circuit is also provided which preliminarily stores a correction value corresponding to an error occuring between the oscillation frequency of the reference oscillator as generated per unit time and the standard oscillation frequency which drives the shift circulation circuit. Upon receipt of a correction timing signal the memory circuit has its correction value substracted at a rate of one circulation cycle per minute, thereby to correct such an error. The correction value indicates a total number of subtractive circulation cycle per hour.
Abstract:
A data read-write apparatus for a magnetic recording medium, wherein, when data represented by coded signals are written in a magnetic recording medium, a binary "1" signal of at least one bit is written in the magnetic recording medium ahead of data being written upon receipt of a clock pulse from a clock pulse oscillator; thereafter a series of binary coded signals denoting the content of the data are written in the magnetic recording medium; when the data are read out from the magnetic recording medium, the binary code "1" signal is first detected; upon said detection, the phase of clock pulses issued from the clock pulse oscillator are synchronized with the timing in which the binary coded "1" signal is read out; upon receipt of a phase-synchronized clock pulse, other binary coded signals stored in the magnetic recording medium in succession to the binary coded "1" signal are read out in synchronization with clock pulses sent forth from the clock pulse oscillator; and the clock pulse oscillator successively produces clock pulses for defining the intervals at which bits constituting data stored in the magnetic recording medium are read out or the intervals at which bits representing fresh data are written in the magnetic recording medium, thereby controlling the phases of the generated clock pulses.
Abstract:
A watch device is adapted to deliver a time counting signal from an electronic time counting means to a display means to effect a display corresponding to the time counting signal. The watch device comprises a switching means for producing an electric signal when it takes a predetermined attitude; a timer means driven, at the point of time when the signal is initiated, to produce a signal having a predetermined time width; and a display control means for effecting a display by the timer means during a time period corresponding to the predetermined time width.
Abstract:
An apparatus for arithmetically processing bill records wherein the printing device is provided with a first memory register having a digit-storing capacity corresponding to a maximum impression length specifically designed for said printing device and a tabset register which has the same digit-storing capacity as the first memory register and in which shifting is carried out in synchronization with that taking place in the first memory register. Tabset positions in the tabset register are determined by key operation so as to cause the digit-storing capacity of the first memory register in which shifting is carried out in synchronization with that occurring in the tabset register to be divided into desired sections corresponding to the widths of a plurality of columns appearing on different forms of bills, thereby enabling numerical values given in multiform bills to be recorded and to be arithmetically processed with ease and said printing device is further provided with a second memory register which has the same digit-storing capacity as the first memory register, in which shifting is carried out in synchronization with that taking place in said first memory register, and which is connected thereto through an adder so as to store vertical totals arrived at by adding up numerical values already stored in the first memory register belonging to the respective columns one line after another of impression on the bill.
Abstract:
A system for transmitting data which comprises serially arranged records of changeable length. Each record is separated from the adjacent ones by two record positioning codes and includes serially arranged words with word positioning codes interposed among them. If the same item word is included in a record and in the immediately succeeding record, the corresponding word in the succeeding record is omitted or simplified during the data transmission, thereby reducing the memory capacity of the memory for storing the data to be transmitted. Conversely, the system can restore the omitted or simplified item words to the original state and then transmit the data thus in the original state.
