摘要： PROBLEM TO BE SOLVED: To provide a control method for an analog and digital watch in which the difference between an existing analog watch and an existing digital watch can be discriminated at a glance by a potential customer. SOLUTION: The sequential control method for a display assembly is provided with overlapped two of an upper-part display device (22) and a lower-part display device (24). The device (22) comprises at least a liquid crystal display cell (26), it becomes transparent in a first state so as to make the device (24) visible, it displays a data item in a second state, it becomes opaque so as to become a reflection type, and it covers the device (24) at least partly. A control means supplies a control voltage, and it shifts the device (22) to the second state from the first state and to the first state from the second state. When the display assembly is set to an operating state that the device (22) is automatically changed over to a state that the device (22) becomes transparent, or to a state that the device (22) becomes opaque so as to become the reflection type, the display assembly is automatically shifted to a mode in which data is displayed by the device (22), and to a mode in which data is displayed by the device (24).

摘要： PROBLEM TO BE SOLVED: To provide a method capable of simplifying the structure of an adjust assembly and effectively and inexpensively adjusting the frequency of a spring balance. SOLUTION: In order to adjust the oscillation frequency of the spring balance, in a first step, the balance spring is manufactured with elastic torque larger than the reference torque corresponding to the reference frequency of the oscillation frequency of the adjust assembly. After the spring balance is assembled, the spring is machined by a laser bean to decrease the elastic torque until the elastic torque substantially reaches the reference elastic torque. To be concrete, laser machining removes material to reduce the height of the balance spring in a certain area, or reduce the thickness of a strip for forming the balance spring. According to this method, the conventional adjusting means, especially a pin with index can be omitted. Thus, the operational error of a clock as a function of position can be prevented.

摘要： PROBLEM TO BE SOLVED: To change the background color of an image or colors of characters and alphanumerics displayed by an electronic appliance having a display part operated by a photovoltaic cell. SOLUTION: The display assembly contains an electro-optic cell (28) of a liquid crystal cell and a photovoltaic cell (61) functioning as a back face reflector for the electro-optic cell. In order to improve the decorative appearance of the display, the photovoltaic cell (61) reflects light at specified wavelengths to produce desired colors in a transparent zone (90) of the electro-optic cell. In particular, the reflected light can be colored by reflection on a multilayered reflection filter including a transparent electrode (69) of the photovoltaic cell. The cell can form a part of the dial plate of a wrist watch.

摘要： PROBLEM TO BE SOLVED: To provide a device by which a time symbol around a circular dial can be read out at night with reference to the circular dial in a small apparatus equipped with an automatic power supply. SOLUTION: In a peripheral lighting device for the scale of a dial 11 in a small apparatus, a case 1 with a built-in movement 14 which drives at least one out of pointers 12a, 12b, 12c with reference to the scale is contained, a power supply 6 which can supply a pulse voltage is contained, an electronic circuit 15 is contained, and the case is covered with a crystal 4 which is extended to the side of the dial by a ring-shaped recessed part forming a flange 17. In the peripheral lighting device, a ring-shaped recessed part 19 is formed at the inside of a base part 18 in order to receive an electronic light-emitting ring 20 formed of a belt piece which comprises an edge part 21 and a connecting lug 22 extended by exceeding the base part 18 of the flange 17, and a ring 30 composed of a semitransparent plastic material is pressed to the ring-shaped recessed part 19 in such a way that the electronic light-emitting ring 20 is held by the low part of the ring.

摘要： PROBLEM TO BE SOLVED: To form a push button mechanism from a click device having an elastically restoring mean in a blade spring shape at a non-operating position and allowing to adjust a force applied on a top of a push button. SOLUTION: This mechanism is provided with a lever 11 on a flat support member 2 and a second member 20. The lever 11 is provided with two pins 14, 16 forming a triangle with respect to a strut 12. The second member 20 is provided with a base part 22 and a U-shaped cutout part 21 separating first and second arms 28, 32. The base part 22 supports a guide mean 23 sliding along a ramp 3 and a control mean 24 driving functions 5, 6. The first rigid arm 28 is rotatably installed on the first pin 14 of the lever 11. The second elastic arm 32 has a cutout 34 on a free end 33 functioning as a support of the second pin 16 at a non-operating position. A click effect is generated when the second pin 16 of the lever slides to the cutout 34, thereby pressing the elastic arm 32 and moving one position to another position.

摘要： PROBLEM TO BE SOLVED: To mass-produce a display element for a clock without producing any defect by providing a strip type plastic material sheet having a sufficient width dimension for producing at least one display element. SOLUTION: A display element 1 is a date disc. The disc is provided with a first outer ring 10 cut from a strip type plastic sheet along an outline line 20. In the outer ring 10, indications 8 about the date, to be more precise, numbers from 1 to 31 are attached. The disc 1 is provided with a second ring 11 formed below the first ring 10 adjacently to it. A recessed structure of the second ring 11 forms a space 12 for receiving a disc for a day of the week. The disc 1 is also provided with a third ring 13 constructed below the second ring 11 adjacently to it. For securing driving for the disc, an internal thread 16 is cut in the third ring 13. In this way, the disc 1 is provided with a step- shaped form having an outline formed by thermoforming. The thickness of a continuous steps 10, 11, 13 and teeth 14 is about 0.15 mm.

摘要： PROBLEM TO BE SOLVED: To reduce the driving energy for a stepping motor as a whole. SOLUTION: A driving pulse with alternate first and second polarities is applied to a coil 3 of a motor 2 to supply a specified quantity of electric energy to the coil 3 while each driving pulse continues. After each driving pulse, rotation or non-rotation of a rotor of the motor responding to each driving pulse is detected. When the rotor is in non-rotation state, the duration of a next pulse is adjusted longer. In this case, a quantity of electric energy supplied to the coil 3 is adjusted separately for a driving pulse of the first polarity and for a driving pulse of the second polarity.

摘要： PROBLEM TO BE SOLVED: To correct time-related data or a date at a second leading position with the starting command control of a chronograph by allowing a pusher head to move in the axial direction from a pause position against a spring force, when the pusher head that is arranged so that it can slide into a recess is pushed in. SOLUTION: A device 1 is provided with a pusher head 2 that is mounted to the end part of a pusher stem 4. The pusher stem 4 is arranged, so that it slides in a cylindrical recess 6 that is provided at the middle part of a clock case. When a pressing force is applied to the pusher head 2, the pusher stem 4 moves in the an axial direction in the recess 6 countering the return force of a spring 12. The spring 12 is arranged in the recess 6 and at the same time touches a bottom part 16 of a gap part 18. An annular groove 20 is provided in the pusher stem 4 and accommodates a sealing gasket 22. The pusher stem 4 moves to a second leading position from a pause position in an axial direction, when pull force is applied to the pusher 2.
