Abstract: The present invention relates to a replaceable decorative cover adapted to be snap-coupled with one of those watches formed of a monolithic rubber bracelet provided in the center with a tapering enlarged section that contains the display of the watch.

Abstract: A method of recording information on and reproducing information from a magnetooptical recording medium which includes first and second magnetic layers. The method includes the step of projecting a light spot onto the medium. When reproducing information, the light spot is projected onto the medium from the side of the magnetic layer. In this method only a high temperature region of the second magnetic layer within a light spot projection portion is changed to a perpendicular magnetization film so that information recorded in the first magnetic layer is transferred to the perpendicular magnetization film of the second magnetic layer. In addition, information which is transferred to the second magnetic layer is detected by using reflected light from the medium which is subjected to the magneto-optic effect from the perpendicular magnetization film of the second magnetic layer.

Abstract: 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.

Abstract: This invention consists of a ski pole with a handle on which a liquid crystal display (LCD) chronometer is detachably mounted. The chronometer is mounted inside the push button at the top of the ski pole handle and held in place by a lens and four set screws. The push button is located as to be actuable by the thumb of the skier.

Abstract: A time piece comprising a cylindrical casing formed of transparent material which is closed at its bottom end by a bottom cover on which is mounted a clock movement whose output spindles are drivingly connected by plates to respective drum-like members provided on their outer peripheries with indicia, representing time, the drum-like members being concentrically arranged so that their indicia can be viewed through a window provided on a sleeve mounted on the casing, the inner side of the sleeve comprising a non-transparent sheet which is cut-away in the region of the window. The time is read off the drum-like members in a vertical direction.

Abstract: A self-contained, battery-powered, hand-held and finger-actuated timer produces switch controlled signals at a series of increasing time intervals for timing athletic games and in form which allows the user to retain visual contact with the game being timed and also so as to leave the user's fingers free for finger signaling, or the like.

Abstract: A clock which includes a member which rotates in a time dependent manner and which has a substantially cylindrical periphery about the axis of generation which has disposed thereabout two axially spaced sets of clockwise sequenced indicia indicative of the time, the two sets being out of phase about the periphery by the angle .alpha. with one set having the indicia inverted relative to the other, the member being so arranged within a housing that a sight element disposed about the periphery can indicate on the appropriate indicia the particular time. Ideally the angle .alpha. is 180.degree.. The invention also consists of a device to convert a conventional clock to such a multi-faceted display.

Abstract: A writing implement containing electrical circuitry for keeping and displaying time. The implement includes an elongated barrel portion with a writing element having a tip portion protruding from one end thereof and an electrical time keeping device defined by an elongated support in the form of a chip or circuit board disposed within the barrel portion and having a plurality of numerical display elements which extend in a row longitudinally of the barrel of the implement and are aligned behind an elongated window which extends across a longitudinally extending opening in the wall of the barrel. Structures are provided for easily retaining and removing a battery with respect to the barrel to arrange it in circuit with electrical circuitry supported by the circuit board. Structures are also provided for easily removing the elongated circuit board from the barrel and replacing it with another board or after it has been repaired.
