摘要:
A display includes a plurality of display arrays, such as a time display section (37), a chronological display section (38), and a chronological split display section (39). An upper or lower polarizer is provided with a light modulating section having a reflection type polarizer. To display only the time, the chronological display section (38) and the chronological split display section (39) are shielded by the light modulating section. For chronological display, the chronological display section (38) is lit, and the chronological split display (39) is displayed or shielded as required by a shutter function.

A time information repeating installation in a radio clock system, which receives advance notice information, distinguishes advance notice content by detecting means 9, sets a transmission start time by addition setting means 10 in accordance with the content, sets an additional period by change period setting means 11, and stores the content into transmission start time storage means 12. When the stored time agrees with the time of a main counter 8, transmission starts. Therefore, even when a sudden time change occurs, the repeating installation can perform transmission at the reception timing of a subsidiary device. The subsidiary device can effectively update time data for summer or daylight savings time.

摘要:
In an electronic timepiece powered by a photovoltaic cell, the supply voltage fluctuates a great deal due to the varying amounts of light received by the photovoltaic cell. This presents special considerations for a low voltage alarm circuit. The present invention combines two alarms. First, there is a charging alarm which responds to voltage and which indicates that voltage is low and that the amount of light should be increased. If the light is increased, the circuit will continue to operate and no reset operation is needed. If on the other hand the voltage drops to the point where the circuit actually stops, a stop alarm is activated. The stop alarm is not responsive to voltage level. Instead, it is responsive to the fact that the circuit's oscillator has stopped. Furthermore, the stop alarm is provided with a memory and it will not automatically be reset if the voltage is increased.
摘要:
A world watch has an hour hand and a minute hand for usual time indication, a plurality of symbols disposed on a dial to represent areas having respective time differences, an area including hand for specifying one of the areas by indicating one of the symbols, a local time indicating hand for indicating the local time of the specified area at least in hours, and a date indicating hand for indicating a date of the specified area. The world watch comprises counters for counting the numbers of driving signals used for driving the area indicating hand and local time indicating hand, respectively; and a drive controlling circuit for generating, when the count of at least one of the counters reaches a predetermined value, a driving signal for driving the date indicating hand in a normal or reverse turning direction based on a judgment whether the predetermined value has been described by an increase in the count or by a decrease in the count. With this arrangement, the standard time and date of an optical area are correctly and easily displayed.

The power consumption of small electronic device having a display opening/closing shutter is lowered. A display shutout control means (10) is provided to stop the operation of a display drive means (60) according to the control made by the display shutout control means (10) in a display shutout state to save power.
摘要:
A small-sized electronic apparatus is provided which, in the case of use as a watch, can be manufactured at a low cost but with the same thickness, size, weight, etc., as a conventional watch and which includes various sensing means for switching and for shutter opening/closing. Display shutout control means 10 accepts a switching signal from switching means 9 and a closing signal from a timer control circuit 14, and issues a control signal. The control signal is fed to a liquid crystal shutter 13 which uses a liquid crystal panel arranged above an information display part 80, to perform opening/closing of the shutter.
