Patent number: 5514440Abstract: An optical recording medium is disclosed, which comprises a substrate having thereon a recording layer which is capable of forming regions having an increased reflectivity by spinodal decomposition of the recording layer upon application thereto of energy of a threshold value or higher. Writing of information is achieved by irradiating the recording layer with no phase separation caused by spinodal decomposition with an energy beam having an intensity causing spinodal decomposition-induced phase separation in accordance with the information to be written. Reading of the information, on the other hand, is achieved by irradiating the recording layer with phase separation caused by spinodal decomposition with an energy beam having an intensity causing no spinodal decomposition-induced phase separation. The medium and the recording system using the same exhibit high sensitivity, high reflectivity, and high contract and conform to the CD or LD standard.Type: GrantFiled: September 28, 1992Date of Patent: May 7, 1996Assignee: Fuji Xerox Co., Ltd.Inventors: Hironori Gotoh, Kiichi Ueyanagi

Patent number: 5383166Abstract: A watch control device comprises a crown with a central cavity surrounded by an annular cavity in the bottom of which is formed a groove. The lateral external face of the annular cavity has a thread adapted to be screwed onto a thread formed on the lateral external face of an external part of a tube screwed into a watch casing. An injected thermoplastic elastomer seal is disposed in the annular cavity. This seal comprises two parts of the same external diameter, but of different internal diameter, the portion of greater diameter engaging in the groove and the portion of smaller diameter being that on which the tube acts in the screwed up position of the crown.Type: GrantFiled: February 3, 1993Date of Patent: January 17, 1995Assignee: Montres Rolex S.A.Inventor: Jacques-Andre Gallay

Patent number: 5299179Abstract: This pushpiece (1) for a timepiece includes a movable head (3) slidingly mounted on a tube (4), said head partially enveloping such tube. The head exhibits a central cylindrical core (5) which penetrates into the tube, at least one O ring seal (6) being located between the tube and the core. A return spring (7) urges the head towards the exterior. The core (5) is extended by a stem (8), the diameter of which is greater than the diameter of the core, the spring being arranged between the stem and the tube. In this manner the spring is located in a sealed zone of the pushpiece and the mean diameter of the O ring seal is less than the mean diameter of the spring.Type: GrantFiled: January 25, 1993Date of Patent: March 29, 1994Assignee: SMH Management Services AGInventors: Marc-Andre Miche, Gerard Palix

Patent number: 5077710Abstract: The caseband (1) of this invention is fashioned from a contoured strip (2) which includes a profile in relief elongated in the longitudinal direction of the strip. This profile may serve a purely decorative purpose but may also have functional applications for instance that of attaching a watch crystal to the caseband. In such case the profile in relief includes projections (3) which define facing slide channels (6) into which the crystal may be introduced.Type: GrantFiled: March 13, 1990Date of Patent: December 31, 1991Assignee: Eta Sa Fabriques d'EbauchesInventor: Paul Gogniat

Patent number: 4502791Abstract: This device comprises a groove (6) made in the internal wall of a through hole (2) of the case (1) giving passage to the stem (3) of the winding crown (4). A gasket (8) is placed in the groove (6). The internal diameter of the gasket (8) is less than the outside diameter of the stem (3) of the winding crown and is thus compacted between the stem (3) and the groove (6). The stem (3) is comprised by an internally screw-threaded pedestal (3') secured to the winding crown (4) and an externally screw-threaded winding stem (3") screwed into the pedestal (3'). As a result, the hole (2) can be made of relatively small diameter, which is an important advantage in an extra-thin watch whose case is of relatively soft precious metal, because the tendency to bend the case, that would be present in the case of a large hole, is overcome.Type: GrantFiled: May 2, 1983Date of Patent: March 5, 1985Assignee: Jean Lassale S.A.Inventor: Pierre Goy

Patent number: 4271498Abstract: A resilient member for connecting a crystal to a watch casing in which the crystal is used for generating acoustic signals. The member is of generally annular configuration with an inner portion rigidly connected to the circumference of the crystal, an outer peripheral portion connected to a supporting member of the watch casing, and a free portion extending between the inner portion and the outer peripheral portion. The free portion has a width and a thickness which permits flexing in a direction normal to the plane of the crystal so that the crystal can vibrate in a direction normal to its plane and act as an acoustical transmitting member.Type: GrantFiled: November 7, 1978Date of Patent: June 2, 1981Assignee: Ebauches S.A.Inventors: Roberto Zafferri, Ali Schneiter, Rene Besson
