Abstract: To graphically portray the diminution of the last minute before commencement of a next hour in a balanced digital time display, six horizontal elements of a pair of 7-segment arrays of display elements are activated immediately after one remaining minute and zero seconds. These six elements are each individually flashed for and extinguished after ten second intervals, in a sequence that begins with the top element of the outermost array, spaced farthest to the left from the next hour digit, and progresses to the middle and bottom elements of that array, followed by the top, middle and bottom elements of an intermediate array, located between the outermost array and the next hour digit. This sequence provides descending flashing elements in three ladder-like steps down each array, the outermost array graphically portraying the diminution of the first thirty seconds and the intermediate array the diminution of the second thirty seconds of the last remaining minute.

Abstract: In an electronic watch, a hand wheel gear 109b in a gear train has a tooth 124 having a profile K so as to prevent the backward movement of a hand 104. During initialization, the gear train is rotated backward such that the hand 104 is turned to the backward movement preventing position, which serves as an initializing position, and a reference position during detection of a hand position. Usually, a backward movement command is issued when the hand 104 is supposed to be at the reference position. The hand 104 is judged to be out of the reference position when its backward movement is detected.

Abstract: A container for drugs which features a cylindrical vial with a radially outwardly flared skirt or axial bulge which symbolically designates the vial as one containing medication requiring special attention. The container may be formed as one or two pieces but in either case there is a portion below the internal bottom wall of the vial which can house a timer unit with a time display. A switch sets a time which remains on display, indicating the last time the switch was actuated, i.e. the last time medication was taken. The timer is mounted in a way so that it may be retained, even though the vial is discarded.

Abstract: An electronic clock includes a usual oscillator and a more accurate oscillator. The usual oscillator generates a first frequency which causes the electronic clock to operate and the more accurate oscillator generates a second frequency which is used as a reference frequency. Referring to the second frequency, the first frequency is measured by a frequency measurement circuit and a deviation of the first frequency from a design frequency is calculated by a processor. According to the deviation, time correction of the electronic clock is performed. Therefore, even if an actual oscillation frequency of the usual oscillator is not stable precisely, the accurate time correction can be achieved.

Abstract: A paging device in combination with an accurate stopwatch includes a stopwatch timer block supported by latent processor element resources. The user directly manipulates, e.g., starts and stops, the timer block without processor element intervention. The processor element is thereby free to service higher priority tasks, e.g., receipt of paging information, and collects stopwatch timer block data at a lower priority level.

Abstract: An electronic device with a calendar function having an input device, so that a desired date can be entered in the electronic device. The day of the week that January 1st falls on in the year corresponding to the desired date is determined. The ordinal number of a week in which the entered desired date falls is determined dependent on the day January 1st falls on. For example, if January 1st is between a first day of the week and a fourth day of the week, the week corresponding to January 1st is deemed as the first week in the year, if January 1st is between a fifth day and a seventh day of the week, the week following the week to which January 1st belongs is deemed as the first week of the year. A display is provided displaying the ordinal number of the week of the year in which the entered desired date falls.

Abstract: Crown setting device for an alarm setting crown and/or a time setting crown in an analog wristwatch uses a rotatable top ring mounted on the watch case, having gear teeth on its underside which mesh with gear teeth on the crown(s) to rotate the crown(s). This serves to set the time and/or alarms with less time and effort than conventional crown setting. Preferably involute gear teeth are used, but a simple version employs the conventional crown knurling as "teeth".

Abstract: An electronic time piece senses and warns the electric residue of a secondary cell having electrodes of conductive polymer to a user during the rapid charge.The electronic time piece converts a kinetic energy produced by the user's motion into an electric energy. The electric energy is then outputted from a power generator coil as a charging voltage for charging a chemical reaction type secondary cell. The charged energy in the secondary cell is used to actuate a time piece circuit for indicating the time.The electronic time piece comprises an electric residue sensor unit which outputs an electric residue detection signal when the voltage in the secondary cell continues to exceed a reference voltage corresponding to an electric residue in the secondary cell for a predetermined time during the rapid charge.

Abstract: A real time clock is arranged to generate output signals indicative of time of day.
