Abstract: Disclosed herein is an optical recording medium for recording informations by irradiating the optical recording medium with a laser beam to form a hole or a deformed part thereon, said optical recording medium comprising a substrate and a recording layer containing at least Te, Se and F in the amounts of from 35 to 94.9 atomic % of Te, from 5 to 25 atomic % of Se and from 0.1 to 40 atomic % of F, produced by a reactive sputtering, said Se being derived from selenium fluoride and a sputtering target of Te or a sputtering target comprising Te-Se-alloy, and a process for producing the same.

Abstract: An entry control device for coded credit cards or the like to be incorporated in a dispensing machine which includes a main body having a card gate gradually narrowed inward to define a passage for passing selected sized cards, a shutter plate pivotally provided behind the passage, a pair of rollers rotatably mounted on corresponding shafts pivotally connected to the main body and adapted to be urged to engage corresponding notches formed in the main body, and a card reader electrically associated with a second shutter plate, by which arrangement, only a proper selected sized card is permitted to enter the internal dispensing mechanism with any odd sized cards or debris advantageously prevented from being forced or jammed into the machine.
