In one antenna unit, a non-electrically conductive resin layer is provided on a core portion of electrically conductive material and a winding portion is configured by a coil wound on the layer. The antenna unit is housed in a band attaching portion of a watch case of a watch, and a watch module is housed in the watch case. In another antenna unit, a core portion and a winding portion wound on the core portion are arranged in a cover case. Openings are formed in side walls of the cover case oppositely positioned to each other, and parts of the outer circumferential surface of the winding portion are arranged in the openings. The winding portion together with the core portion is supported to the inner surface of the cover case by adhesive portions interposed between the cover case and the winding portion.

The present invention relates to a timepiece and an electronic apparatus, which comprise a casing, a digital face and a time counting module, both being provided in the casing. A bulb-shaped solar battery element is mounted on the digital face. The bulb-shaped solar battery element is allowed to receive the external light sufficiently to generate the electric power efficiently.

An antenna includes an elongate laminated core, a core case having an electrical insulating property and housing the core, and a coil wound around the core between both end portions of the core through the case. The core has a first and second groups, each including thin plates of amorphous soft magnetic alloy laminated with each other, and is configured by stacking the first and second groups one another. Each of the thin plates of the core includes flanges provided at both end portions thereof, and a coil wound portion between the both end portions, and the case includes projections, which push the both end portions of the thin plates of the second group to separate from the both end portions of the thin plates of the first group in the laminating direction of the thin plates of the core while the core is housed in the case.

A device is used for precisely measuring an electrocardiographic wave and sphygmus. The device displays a number of sphygmus or the highest and lowest blood pressure on the basis of measured data. In the device, it is judged if an electrocardiographic wave signal generated from an electrocardiographic wave detecting circuit and the sphygmus signal generated from a sphygmus detecting circuit have been output in a corresponding manner to each other. If not, or if one of the above signals has not been detected, either the gain of the electrocardiographic wave detecting circuit or the gain of the sphygmus detecting circuit is increased so as to allow a precise detection of the signal.

Measurement of electrocardiographic wave and sphygmus

An electronic key apparatus wherein an encrypted code for unlocking an electronic lock is stored in an encrypted code storage register. A password is stored in a password storage register. The same password as that stored in the password storage register, is input via a switch. The password input by the switch is compared with the password stored in the password storage register, by a coincidence detection circuit. When a coincidence is detected, the encrypted code stored in the encrypted code storage register is transmitted to the electronic lock, by a transmitter.
