摘要： A telephone includes a telephone body, a handset and a telephone network line hold mechanism. The telephone body includes a handset cradle on which the handset is placed, a plurality of operation buttons and the like. The telephone is placed in the offhook state when the user lifts the handset from the handset cradle and placed in the on-hook state when the user places the handset on the handset cradle. The telephone network line hold mechanism is energized when the user places the handset on the telephone body at its position in which the offhook state of the telephone is retained.

摘要： The present invention aims to provide a toner having excellent developability and excellent low-temperature fixability without causing adhesion of ejected sheets even in a high-speed oilless fixing system and capable of preventing a frameless printing from causing a twisted offseting phenomenon. Specifically, provided is a toner having toner particles including at least a binder resin and a colorant, in which, when the toner is dissolved in a tetrahydrofuran (THF) solvent at 25° C. for 24 hours, the ratio of a THF-soluble matter having an intrinsic viscosity of 5.0×10−2 dl/g or less with respect to the total amount of the THF-soluble matter in a GPC-RALLS-viscometer analysis is 15.0 mass % to 60.0 mass %, and the ratio of a THF-soluble matter having an intrinsic viscosity of 1.5×10−1 dl/g or more with respect to the total amount of the THF-soluble matter in a GPC-RALLS-viscometer analysis is 20.0 mass % to 40.0 mass %.

摘要： In a liquid crystal display device having a voltage-driven liquid crystal cell sandwiched between two spaced polarizers, the cell comprises a liquid crystal layer having a twisted molecular alignment with no applied voltage and also having an optical rotary power with respect to visible rays. In the vicinity of the cell or in close contact therewith, there is disposed an optically anisotropic layer having an optical rotary power smaller than that of the cell.
