摘要： PROBLEM TO BE SOLVED: To provide a stepping motor rotor in which another member does not exist on the outer circumferences of a rotor shaft having reduced bearing friction with a tenon having a diameter smaller than a commonly used value and a rotor magnet.
SOLUTION: This rotor is structure so that a rotor shaft made of a metal member is almost machined to have a shaft diameter equal to that of a tenon as both end portions by, for example, cernterless machining, and a resin-made rotor pinion is formed around the rotor shaft member on the one surface of a rotor magnet. Further, the rotor includes a rotation stop means for the rotor shaft of the rotor pinion and a movement preventing means in the shaft direction which are formed by crushing part of the rotor shaft or press-fitting another material into the rotor shaft at a portion contacting the rotor shaft contacts a resin material forming the rotor pinion. Still further, part of the resin material forming the rotor pinion may communicate the other surface of the rotor magnet through the hole of the magnet so as to be a rotor seat equivalent member after being cured.

摘要： PURPOSE: To improve an operationability of indicator standard position detection by forming a spring part to escape in the case a row of indicator rings rotate in right direction and a stopper part to stop the row of indicator rings as one of a row of indicator rings. CONSTITUTION: Gears 9 of a numbering wheel 8 to compose a row 6 of indicator ring are made of a material of synthetic resin and a part of the gears 9 is joined with a boss 21a installed in a receiving member to journal the row 6 of rings. A spring part 9e and a stopper part 9a at the tip of the spring part 9e are unitedly formed, wherein the spring part can be elastically deformed by rotary driving torque of the numbering wheel 8 in the case the row 6 of rings are driven in the right rotary direction and the stopper part is to stop the driving of the numbering wheel 8 in the case the row 6 of rings are driven in the inverse rotary direction. Consequently, the numbering wheel 8 can be kept in the rotation stopped state by a prescribed switching operation before pointer installation and in the case pointers 2-4 are fixed in desiring initial positions, no complicated operation is needed at the practical use of a clock.

摘要： PROBLEM TO BE SOLVED: To overcome the problem that, in a solar timepiece with illumination in which a solar cell and an EL light-emitting layer are provided on the lower surface of a translucent character plate at which an hour character is formed, a character plate around the hour character is illuminated and the hour character is hard to be recognized because it is blurred when the EL is lit as the hour character is in the shadow if it is small, resulting in posed limit on design. SOLUTION: A pointer display type timepiece comprises an illumination device such as an LED panel 5 with a solar cell 1 as a drive source. The solar cell is disposed under a translucent region 2 of a character plate 1 while the illumination device is disposed under an opaque region 3 with an opening. By using the opening as the hour character 4, a solar clock with illumination which is excellent in design can be presented. The opaque region 3 and the hour character 4 are printed to provide the hour characters such as a figure.

摘要： PROBLEM TO BE SOLVED: To reduce the time until normal handling of a needle is performed by prohibiting the passage of all drive pulses and stopping the drive of a step motor when a drive judgment circuit judges as non-rotation when a control circuit is passing a drive pulse for a low voltage with the maximum energy. SOLUTION: When a power supply voltage is equal to or less than 1.15 V, the voltage of a secondary power supply 13 drops due to charge shortage. When it becomes 1.15 V or less, this conditions is detected by a power supply voltage detection circuit 14 and a rotation judgment signal is sent from a drive judgment circuit 18 to a control circuit 15. The control circuit 15 prohibits the passage of a normal drive pulse and allows the passage of a drive pulse for a low voltage, instead. The drive pulse for a low voltage is a rapid pulse for every two seconds which is different in handling of a needle from a normal drive pulse, namely a two-second needle-handling pulse, and a user can detect that a voltage has dropped from the needle handling state of a second needle. Further, when the control circuit 15 is allowing the drive pulse for low voltage with the maximum energy to pass, it prohibits the passage of all drive pulses if the drive judgment circuit 18 judges to be non-rotation.

摘要： PROBLEM TO BE SOLVED: To optimally control a drive pulse by discriminating a current wave form when a drive force is extremely large from that of a drive force when the drive force is normal.
SOLUTION: An electronic clock is provided with a generation means, a recharging means accompanying a voltage fluctuation, a means 21 for judging the movement of a rotor 70 from an induced voltage, a means 22 for creating a strobe pulse for detecting the above induced voltage, and a drive pulse control means that is controlled by the judgment means 21. In the clock, a resistor for detecting the above induced voltage is set to 30 times the resistance of a coil 60 or smaller so that the detection level of the above induced voltage can be slow when the drive voltage is high.

摘要： PROBLEM TO BE SOLVED: To obtain an electronic watch where it is easy to find even a small second band is making an alarm motion by moving the hand for alarming by a first pulse. and a second pulse that is outputted to a specific range value from the output of the first pulse. SOLUTION: An electronic watch is provided with an alarm function by the abnormal movement of a small second hand 1, and the abnormal movement of clock hands is made by a first pulse and a second pulse that is outputted in 250 ms or more and less than 1 second from the first pulse. The small second hand 1 is first located at the position of the small second hand 1a. Then, the small hand 1 moves to the position of a small second hand 1b by the first pulse. After that, the small second hand 1 moves to the position of a small second hand 1c by the second pulse that is outputted 250 ms later. Therefore, the small second hand seems to stop at the position of the small second hand 1b momentarily while the small second hand 1 moves from the position of the small second hand 1a to that of the small second hand 1c for a user, thus informing the user of the advance of 2 seconds due to the small second hand 1.

摘要： PROBLEM TO BE SOLVED: To reduce power consumption and extend driving time by preparing a plurality of second drive pulse, and selecting the second drive pulse of proper size from the detection results of rotation and no-rotation. SOLUTION: A voltage detection circuit 3 controls a pulse group selection circuit 10 when the voltage of dual layer electric capacitor 2 lowers to 1.2 V or less, and an ordinary pulse selection circuit 8 is switched to the first pulse creation circuit 107 and the second pulse selection circuit 108. Then, first drive pulse P1 capable of driving to 0.9 V is outputted from the circuit 107, and second drive pulse P2a capable of driving to 1.15 V is outputted from the second pulse creation circuit 207 to rotate a step motor 13. Next at 2 second later, a pulse P1 is outputted and this operation is repeated to drive a hand at every 2 second. If the voltage of the capacitor 2 lowers further and driving with pulse P2a becomes unavailable and no-rotation is detected with the rotation detection circuit 12, the second drive pulse P2b with larger drive force by 1 rank is selected to output.
