Abstract: A film stretched uniaxially in the transverse direction selectively is obtained by preventing a phenomenon that the film is stretched also in the longitudinal direction in stretching the film in a direction transverse to the conveying direction. A film F is stretched in the transverse direction while being gripped with clips 2 each having a corrugated upper teeth part (holding member piece) 12 and a corrugated lower teeth part (holding member piece) 11. Furthermore, the film F is shaped into a wavy form using corrugated gripping members 6a and 6b and stretched in the transverse direction while being held with the clips 2 having the holding members.

Abstract: An adapter and signal transmission cables for hands-free telephone system including a mobile telephone, car audio equipment such as a cassette recorder and a mobile telephone adapter. The mobile telephone adapter includes an adapter body, which can be pushed inside the cassette recorder; a hands-free microphone; a first signal transmission cable for connecting the adapter body and the mobile telephone; and a second signal transmission cable for connecting the hands-free microphone and the mobile telephone. The adapter body has a housing that resembles a cassette tape externally and a magnetic recording head installed inside. One end of the first and second signal transmission cables are joined together and connected to a plug, and the plug is capable of plugging into the voice input/output socket of the mobile telephone. When the mobile telephone picks up incoming voice signals, the signals will be transmitted via the adapter to the cassette recorder, which is then broadcast out through its loudspeakers.

Abstract: A method of making a cage for use in a roller bearing comprises the steps of forming an inner circumferential groove centrally in an annular-shaped workpiece made of metal to define a circumferentially-extending side ring section on either side of the groove, punching the workpiece to form a plurality of axially-extending, circumferentially spaced-apart pockets for receiving rollers, and roughly abrading the outer peripheral surface of the workpiece. The punching and abrading steps inherently cause the outer peripheral surface of the workpiece at the side ring sections to become wavy, with a plurality of alternating recessed and raised portions. As a result of the abrading step, the difference in depth between the tops of the raised portions and the recessed portions is in the range of between approximately 60 .mu.m to 70 .mu.m.

Abstract: A cage for use in a roller bearing, which is made of metal, comprises thin portions formed axially centrally of the cage, thick portions formed at opposite sides of the thin portions, a plurality of pockets in which the rollers are received formed extending axially and spaced apart from one another circumferentially, and rugged portion including recessed portions formed in the outer peripheral surface of the at opposite sides of the pockets, and raised portions formed between two adjacent recessed portions and each having a cylindrical surface with a constant radius of curvature.
