摘要： PURPOSE:To prevent a possible time deviation by rotating a rotor of a stepping motor in opposite direction to each other between the timing of displaying time and that of generating power. CONSTITUTION:In this dial display type dynamo timepiece, with a further turning of a crown 37 for generation of power clockwise, a rotor 22 continues to rotate counterclockwise to generate a magnetic flux in a stator 21 and current is induced in a coil 20 to charge a power source 6 through a charging circuit 12. Here, when the crown is released or turned counterclockwise, a rotating force of a second intermediate wheel 36 is lost so that a pinion part 35a of a clutch wheel 35 returns automatically to a position of being separated from a first intermediate wheel 34 while a switching terminal 41c is separated from a switch pattern 43 to turn OFF a switch. At the same time, a counting means 14 stops counting to correct its stoppage on generating power. After the end of the correction, the normal tickling is started.

摘要： PURPOSE:To obtain a timepiece structure for dust-, sweat- or waterproofing which has sureness and permits reduction in cost by coating the timepiece with a heat shrinkable resin and using a smaller number of parts and simple techniques. CONSTITUTION:A module 1 is sandwiched by two sheets of film-shaped heat shrinkable materials 2 consisting of the transparent heat shrinkable resin such as PVC or olefin and the materials 2 are heated and shrunk by hot wind, etc., to bring the same into tight contact with approximately the entire surface of the module 1. The material 2 on the front face of the timepiece assures a space 11 for the hands by the presence of a dike 12. A switch button 3 is pushed from beyond the film of the material 2 to apply and external operation input to the timepiece function, etc. An oscillation diaphragm 6 which is adhered with a piezo-electric element 7 and generates acoustic signals such as alarm sounds is held in tight adhesion under the high pressure uniformly over the entire surface by the material 2 and the shrinkage force thereof, by which the clattering of sounds, etc., are prevented. Since the sealed module 1 has no problems any longer in waterproofness, the module can be put into a case 4 integrated with, for example, a band having many spacings.

摘要： PURPOSE:To obtain a time correcting system which can be operated easily, by selecting successively and cyclically each state of low speed correction, correction stop, high speed correction and correction stop, by a correction switching operation. CONSTITUTION:When a clock is set to a correcting state by drawing out a stem, a switch S1 is closed, an inhibitor 41 becomes off, and also AND gates 37-40 become off through AND gates 33-36 by FFs 30-32 of a reset state. Subsequently, an input to signal forming circuits 44, 45 is cut off, and a step-motor 47 does not turn. Subsequently, when a switch S2 is set to an on-state once by turning the stem to the left, FFs 25, 32 become a set state through a differentiation circuit 22, the gate 37 becomes on through the gate 33, and the motor 47 rotates forward at a low speed by one second pulse phi from a frequency dividing circuit 18. Subsequently, when the switch S2 or S3 is turned on once again, the motor 47 stops in the same way, and subsequently high speed forward rotation, stop, etc. of the motor 47 are selected successively and cyclically. With respect to reverse rotation of the motor, too, it is executed in the same way, and a time correcting system which can be operated easily is obtained.
