摘要:
A timepiece includes: a casing; a light transmission part; a function part; and a glue adhering the light transmission part to the casing. The casing includes: a projection projecting from an inner circumferential surface and extending along a circumferential direction; and a protrusion protruding from the inner circumferential surface and determining a position of the light transmission part. A lateral surface of the light transmission part is adhered to the inner circumferential surface. A peripheral part of a bottom surface of the light transmission part is adhered to a top surface of the projection. An outer circumferential surface of the function part extends along an inner surface of the projection. A space is present in a facing region where the projection faces the function part along the light transmission part. The space is wider in a specific section including the protrusion than in a section different from the specific section.
摘要:
The invention relates to a wrist device, particularly to a fastening mechanism of a cover part and a plastic body part of the wrist device. The fastening mechanism comprises a fastening structure, which in turn comprises a projecting grip structure extending at least partly into the body part, setting against a positioning surface of the body part, and blocked in relation to the mounting direction of the cover part to prevent the fastening structure from moving in a direction opposite to the mounting direction once the fastening structure has been pressed into the body part.

摘要:
An electronic device includes a display; an upper housing surrounding a periphery of the display and forming a front of the electronic device; a lower housing coupled to the upper housing and forming a rear of the electronic device; and a window waterproof member disposed in an aperture between the upper housing and the periphery of the display. The window waterproof member includes an outer sheath composed of a first material; and an inner core composed of a second material more rigid than the first material and disposed substantially in the outer sheath such that each of an upper surface and a lower surface of the inner core facing the front and the rear of the electronic device, respectively, does not protrude out of a periphery of the outer sheath.
摘要:
The case includes a middle part (3) and a back cover (5) delimiting a compartment (7) closed by a glass (10), made of a transparent material resistant to temperatures above 500° C., said glass being bonded or welded at joint zones (15) at least partially covering the shoulder (4) of the middle part (3). It is characterized in that the inner face (11) of the glass (10) includes an enamel deposition (20) formed on the zones of the joints (15) with the shoulder (4) of the middle part (3), either in a hollow (14), or on the surface of said inner face (11).

摘要:
In the manufacture of a watch case part comprising a glass and a middle having an opening for the glass, the following operations are carried out: first, a metallic coating is deposited on a peripheral portion of the glass, then one or more elements are formed on the coating by moulding a molten material having an affinity for the metal forming the coating, whereupon the glass is secured to the middle through the intermediary of the fastening element. The fastening element may consist of a heel extending around the periphery of the glass or of fastening studs extending at right angles to the plane of the glass. In some cases the fastening element may also act as sealing element.
摘要:
A liquid crystal composition comprises at least two compounds selected from the group consisting of trans-4-alkylcyclohexane-1-carboxylic acid-4'-(4"-alkylphenyl)-2'-chlorophenyl ester having the general formula: ##STR1## wherein R and R' are normal chain alkyl groups containing 2 to 7 carbon atoms, these compounds making up 30 mole % or more of the total composition, and at least one compound selected from at least one of the group consisting of 4-alkylbenzoic acid-4'-(4"-alkylphenyl)-2'-chlorophenyl ester having the general formula: ##STR2## wherein R and R' are normal chain alkyl groups containing 2 to 8 carbon atoms and the group consisting of 4-alkoxybonzoic acid-4'-(4"-alkylphenyl)-2'-chlorophenyl ester having the general formula: ##STR3## wherein R and R' are normal chain alkyl groups containing 2 to 8 carbon atoms. This composition not only have a wide nematic temperature range assuring operation at a low temperature of less than -20.degree. C. but also have a low viscosity and excellent response.
