摘要： PURPOSE:To provide a quartz watch free of batteries by magnetically coupling a quartz oscillation type time reference source and a balance wheel with a magnet to govern speed with a power from a power source mechanism which converts a part of kinetic energy into electric energy depending on the magnet attached to the balance wheel of an escape mechanism with an ordinary spring. CONSTITUTION:A magnet is attached to a balance wheel 7 of a mechanical type watch. This magnet is magnetically coupled with a generation coil 9 of a power generation source mechanism 11 in a contactless manner and with the movement of the magnet, voltage is induced in a generation coil 9. This voltage is rectified to a steady- state voltage with a constant voltage circuit 10 and drives a quartz oscillation circuit 12 of a quartz oscillation type time reference source 14 to produces a time reference signal via division 13 into a specified frequency. A governor mechanism 17 regulates the cycle of rotational vibration of the balance wheel 7 with the magnet based on the time reference signal from a voltage division circuit 13 and is composed of a governor coil 16 and a governor circuit 15. The governor circuit 15 runs a control current to a governor coil 16 according to a deviation in the phase between the time reference signal from the voltage division circuit 13 and the cycle of the rotational vibration of the balance wheel 7.

摘要： PURPOSE:To save lithium metal material in order to cut the cost by using a square cut lithium metal thin plate which is inscribed in a bottom of a round dish type negative container as negative active material. CONSTITUTION:A negative active material 21 is formed with a square lithium metal thin plate which is inscribed in a bottom of a round dish type negative cotainer 1, provided facing to a positive active material 3 comprising a pressed powder of manganese dioxide through a separator 4, and electrolyte is poured to form a circular flat lithium battery. Thus, the yield of lithium material is greatly improved because the negtive active materials 21 which are blanked from a lithium material by pressing are not circular, the resource can be saved, and the battery can be thinned because spaces 8 at the four corners of the bottom of the negative container 1 can be utilized for the electrolyte 7.

摘要： PURPOSE:To reduce the thickness of a digital display electronic watch by limiting the member to be interposed between a windshield glass and a back cover only to the display panel, and disposing other members in parallel with the windshield glass. CONSTITUTION:A TN type liquid crystal display device 2 consisting of an upper polarizing plate 91, an upper substrate 21, a lower substrate 22 and a lower polarizing plate 92 and a reflection plate 10 is disposed between a windshield glass 1 and a back cover 6, and a circuit substrate 31 consisting of a flexible sheet mounted with other parts, an IC chip 4 and a crystal vibrator 7 and a thin-type battery 5 are disposed in parallel with the windshield glass 1. Hence, the windshield glass 1 and back cover 6 may be made thin, and the reduction in the thickness of the watch down to extreme of thickness is made feasible by interposing a minimum required member therebetween without decreasing their mechanical strength.

摘要： PURPOSE:To hold strong magnetic characteristics, and to obtain a material recognized as a noble metal by compounding a platinum-cobalt group magnet alloy and pure platinum or a nonmagnetic platinum alloy by plastic deformation and bringing mean platinum content to a specific value or more. CONSTITUTION:The platinum-cobalt group magnet alloy and pure platinum or the nonmagnetic platinum alloy are compounded by plastic deformation, and mean platinum content is brought to 85% or more. For example, a 77% platinum-cobalt alloy plate in 1mm. thickness and a pure platinum plate in 0.6mm. thickness are stacked alternately in the same number and brought into contact by pressure, and rolling and annealing are repeated, thus obtaining a laminated plate in 2mm. thickness. The composite material is thermally treated under the same conditions as a standard platinum-cobalt alloy (a 77% platinum), and the composite material magnet having the magnetic characteristics of the maximum energy product of 6.3 mega gauss oersted (approximately forty percent decrease from a standard platinum cobalt alloy) and mean platinum content of 85.6% is obtained.

摘要： PURPOSE:To improve liquid leakage-proof properties by a method wherein the anode and cathode cans are simultaneously transformed during calking work. CONSTITUTION:A folded end 82 is in a semi-finished state wherein a margin for plastic deformation as indicated by an arrow 83 is inwardly left and, during calking work, the end 41 of the anode can 4 for providing an opening and the folded end are inwardly folded together for sealing purposes. At this time, the end 41 for providing the opening experices spring back in the direction indicated by an arrow 9. However, because the folded end which has been plastically deformed together with the end 41 also experiences the spring back, the compressive force of a gasket 7 is not reduced because of the spring back of them. Accordingly, a sufficient compressive force is maintained in the gasket 7 and sealing reliability is improved.
