Abstract: For facilitating the work of applying a pivotal member, which is to be pivotally connected to a base member, with a satisfied biasing force, a coil-shaped torsion spring is mounted on the pivotal member having one end thereof pressed on a projection of the pivotal member, then the pivotal member is moved to the base member in such a manner that the end of the torsion spring is brought into abutment with and pressed against a stopper portion of the base member while releasing from the projection of the pivotal member, and the pivotal member is further moved toward the base member until the pivotal member is properly set to the base member.

Abstract: A portable telephone set for transmitting and receiving signals has an alarm element for generating an alarm signal in response to a preassigned call signal. The alarm element can be selectively put into a silent mode without generation of a ringing tone. The telephone set comprises a main unit for transmitting and receiving the signals containing the call signal, and a subunit, remote from and coupled to the main unit either electronically or by a cable, for mutually communicating with the main unit. The subunit receives the alarm signal when the alarm element is in the silent mode and produces an indication at the subunit that the main unit has received a preassigned call signal. The subunit can also include means for sending commands to the main unit.

Abstract: An electrophotographic toner suitable for use in an image-forming apparatus employing an organic photoconductor is disclosed which comprises toner particles and, adherent to the surface thereof, magnetic particles having an FeO content of 17% by weight or lower, a specific surface area of from 2.5 to 6 m.sup.2 /g, and an octahedral or hexahedral particle shape. The toner functions to prevent toner components and paper dust from adhering to the surface of an organic photoconductor, and has satisfactory moisture resistance.

Abstract: An improved composition is disclosed which consists of organic resins and silanes. The compositions are useful finishing resins for textiles, fibers and paper. An example of the improved composition is a copolymer resin containing at least one type of acrylic acid ester combined with at least one type of unsaturated aliphatic acid and, a silane containing epoxy groups.
