摘要:
A photosensitive layer of an electrophotographic photoconductor has at least one phthalocyanine compound, wherein the photosensitive layer contains a metal phthalocyanine compound bonded by an o-phthalonitrile compound as a ligand. The o-phthalonitrile ligand is present in an amount from about 100 nmol to about 200 nmol with respect to 1 mol of the phthalocyanine. The resulting electrophotographic photoconductor exhibits a high potential retention rate. A method for making such an electrophotographic photoconductor is also disclosed wherein a photosensitive layer is formed by coating, with a coating layer, to obtain a photosensitive layer having a high potential retention rate.

An electrophotographic photoconductor includes a phosphinate additive in a photosensitive film that improves the stability of the coating liquid for the photosensitive film. The electrophotographic photoconductor includes an electrically conductive substrate and a photosensitive film on the substrate. The photosensitive film contains a charge generation agent and a phosphinate compound. The photoconductor may be of either a monolayer or a laminate construction. In the case of a laminate type photoconductor, the phosphinate compound is incorporated into the charge transport layer. A method of making an electrophotographic photoconductor adds a phosphinate additive to the coating liquid for a photosensitive film to improve stability of the coating liquid. The method involves producing a coating liquid containing a phosphinate compound and coating a conductive substrate with the coating liquid to form a photosensitive film.

An electrophotographic photoconductor includes a conductive substrate and a photosensitive layer formed on a substrate. The photosensitive layer includes a phthalocyanine compound as a charge generation substance. An embodiment of the photosensitive layer contains a first phthalocyanine compound as a main component and a second phthalocyanine compound as a secondary component and as a result, has greater ability to generate negative charges than the ability of the first phthalocyanine compound.

An electric power path switching method for switching a first electric power path from a built-in rechargeable battery in a communication device and a second electric power path from a charger for charging the rechargeable battery which can be connected to the communication device by plugging in and out, includes dividing a load of the communication device into two systems of a first load and a second load; supplying electric power to the first load from the first electric power path; and supplying electric power to the second load from the second electric power path when charging the rechargeable battery by the charger and from the first electric power path when the rechargeable battery is not charged.
摘要:
A method for hand-over processing is provided in which excellent speech quality is maintained and needless and wasteful hunting of a base station is not performed by coping properly with various conditions of radio waves in which a mobile terminal is put and power consumption is reduced. The mobile terminal is measuring, at fixed intervals, a radio wave receiving level provided by the base station being presently operated for a telephone call. When a variation amount of the receiving level being a difference between a present receiving level and a receiving level measured last time is greater than a predetermined threshold value, the hand-over processing is performed and base station hunting processing to hunt a base station to which connection of the mobile terminal is to be handed over, is started. In the base station hunting processing, the hand-over selection level is used as the receiving level.
