Abstract: A metal halide discharge lamp which essentially permits disusing mercury is provided. The metal halide discharge lamp comprises a refractory and transparent hermetic vessel, a pair of electrodes fixed to the hermetic vessel, and a discharge medium sealed in the hermetic vessel and containing a first halide, a second halide, and a rare gas. The first halide is a halide of a metal which achieves a desired light emission. The second halide has a relatively high vapor pressure, being at least one halide of a metal which is unlikely to emit a visible light compared with the metal of the first halide and acts as a buffer gas.

Abstract: In a wrist watch equipped with a receiving device, an antenna 19 having an antenna winding 19b, wound around an antenna core 19a with the end thereof being fixed, and having a conductible antenna terminal sheet 19d secured to an antenna winding frame 19c is inserted from a notch 10k in a dial 10 and secured with a screw 35 to an antenna support plate 33 which is secured to a circuit substrate 22, there by conducting the antenna 19 and the watch module. The construction ensures simplification of the watch module structure and easy conduction and securing of the antenna and the watch module and secured, with little influence on the receiving performance.

Abstract: An electronic diving wristwatch having a pressure sensing depth meter provided in a projection on a case of the watch without interferring with the existing crown, pushbuttons, etc. The depth meter has a piezoelectric type sensing element which produces electrical output in response to the water pressure. The output is converted to a water depth which is displayed in a digital display window of the watch.

Abstract: An electronic timepiece comprising a module composed of four constitutional elements, i.e. a liquid crystal cell, a liquid crystal cell position determining member, a circuit substrate and a protective cover is disclosed. To the protective cover are secured switch parts each having one end connected to a contact on the circuit substrate and the other end connected to an electrically conductive portion of a push button.

Abstract: A wristwatch includes a module, and a display section overlying the module. The module has a recess which surrounds the display section and which accommodates a solar cell unit having a window therein for accommodating the display section. The unit is located by the co-operation of the edge of the window with projecting portions on the module. The upper surfaces of the display section and the solar cell unit are substantially flush. Support members for supporting the display section are electrically connected with a battery of the watch and have spring portions which are electrically connected to the solar cell unit.
