Abstract: An electronic watch including a time counter, a day counter and a month counter for developing counts respectively representing time of the day, day of the month, and the month. The day counter is responsive to a control signal for limiting a maximum count of the day counter to 28, 29, 30 or 31 days. A control signal circuit develops the control signal and applied the same to the day counter for limiting the maximum count of the day counter to 31 days during a long month, 30 days during a short month, and 28 or 29 days during February. The watch further includes a display responsive to the respective counts of the various counters for displaying time of the day, day of the month, and the month.

Abstract: A timepiece has a wheel and pinion mechanism having upper and lower shafts rotatably mounted in bearings which are fixed in a pair of spaced apart plates. The bearing fixed in one plate has a cylindrical portion which surrounds the pinion portion of the wheel and pinion mechanism and which is spaced therefrom a slight distance which is sufficiently small to enable the pinion portion to abut the inner wall of the bearing cylindrical portion in the event the wheel and pinion mechanism tilts on its lower shaft a predetermined amount from its intended orientation thereby preventing falling of the mechanism during assembly.

Abstract: An automatic chord generating circuit for a digital polyphonic tone synthesizer having one or more keyboards. Key operated switches are connected in groups corresponding to the notes in an octave. A signal source is selectively connected by the closed switches of each group in sequence to associated ones of a plurality of signal lines. A priority circuit selectively connects a signal from only one line at a time to a corresponding one of a plurality of output lines, so that operation of more than one key in an octave produces only one output signal at a time. A switching logic circuit, responsive to digitally coded input signals identifying any one of a plurality of different chords, connects the single output signal from the priority circuit to additional ones of the output lines for activating multiple notes within the octave.

Abstract: An electronic timepiece including an optical display for both the time and the alarm time setting, an audible alarm, an alarm circuit, an optical display to indicate the state of operation of the alarm circuit, and a means for determining in advance whether the alarm circuit will be operated only once or every time the alarm time setting coincides with the time. Furthermore, the single optical time display is shared to indicate the time and to indicate the alarm time setting while the alarm time is being set. Also, the optical display to indicate the state of operation of the alarm circuit indicates if an alarm setting has been made and whether the alarm setting will occur only once or repetitively.

Abstract: A digital clock having backlash-free gearing between a step motor and digit wheels that indicate time. The gearing includes an input pinion connected to the step motor, intermediate gearing driven by the pinion and an output ring gear driven by the intermediate gearing and connected to drive a seconds digit wheel of the clock mechanism.

The bracket tilts as well as pivots to permit the intermediate gearing to properly mesh with both the input pinion and the output ring gear.

Abstract: A combination of an electronic timepiece with a liquefied gas fueled cigarette lighter is proposed. A common source battery is used for the bath main constituents. The spark ignition circuit for the gas lighter is fitted with a diode for the prevention of otherwise possible electrical switching shock as appearing during the on-off control of the high voltage spark generation for igniting the fuel gas. Several points of the overall circuit are positively earthed for the same purpose.

Abstract: A carillon keyboard instrument is provided for playing bells and auxiliary bell tones, with a pedal provided for allowing the player to adjust the relative intensities of the major and minor tones of the bells. The instrument utilizes two sets of vibrator bars, a first set for generating major tones, and a second set for generating minor tones. By mixing the derived signals from corresponding major and minor vibrator bars, and adjusting the relative intensity of the minor signal strength, a new flexibility is provided to the instrument player for generating desired Flemish bell tones.

Abstract: At least one cylinder driven at a constant speed is contained in a casing and a dial plate mounted on the casing is provided with a window extending in the direction of the cylinder. The upper edge of the window is marked with digits. The outer periphery of the cylinder is divided into two sections by a line inclined a definite angle with respect to the axis of the cylinder, and the two areas are coloured by different colours. The inclined line cooperates with the digits to display time. When two or three cylinders are used it is possible to display hours, minutes and seconds.

Abstract: A solid state electronic relay system for a pipe organ having at least one input register connected to one or more organ manuals, respectively, to receive parallel input signals therefrom, and respectively convert same into a time based serial digital signal wherein each note of the keyboard occupies a particular interval of time in the digital signal. The serialized signal of an input register propagates through a digital delay line at a predetermined clock frequency. Selected ones of the delayed digital signals provided thereby are tapped to derive octave and mutation pitch signals. Accessory circuits receive the serialized digital signals and using combinational and sequential digital techniques modify the digital signals to provide reiteration, pizzicato, sostenuto and the like effects. The tapped signals and modified signals are selectively combined with logical gates under the control of the organ "stops" to provide the unification and accessory functions.

The safety lock system counts an intermittent touch operation effected on the touch electrodes, thereby allowing the introduction of a time information correction command only when the touch operation is repeated over a predetermined number of times within a predetermined time period.
