Abstract: An electronic apparatus of the clamshell type includes a hinge bracket receiving the back surface of a display enclosure. The hinge bracket takes a closed attitude, where the display enclosure is superposed on a main body enclosure, to an opened attitude, where the display enclosure is flipped to open relative to the main body enclosure. When the display enclosure is set at a specific angle position during establishment of the closed attitude of the hinge bracket, the screen of the display panel is partly uncovered outside the edge of the main body enclosure. The user of the electronic apparatus is allowed to look at an image or images on a partial screen. Such a partial screen provides the functions identical to those of a so-called sub-display panel. A conventional sub-display can be omitted. The electronic apparatus is allowed to enjoy a wide variety of design.

Abstract: The present invention relates to a portable terminal device, such as a cellular phone, which has a screen display section, such as an LCD module, in its upper part and a key manipulation section having an array of plural keys in its lower part. The portable terminal device has a removable battery and is highly protected from water especially in a battery area. There is provided a pair of inner housings, that are a backside inner housing and a front side inner housing, which form a battery compartment having an opening for battery insertion/removal. A key manipulation sheet is disposed on the front side inner housing, and the whole components are covered with a pair of outer housings.

Abstract: A portable terminal device which having a lower part; an upper part openable and closable in relation to the lower part; a magnet and a magnetic sensor attached to the lower part; and a magnetic plate which is attached to the upper part and leads the magnetic force of the magnet to the magnetic sensor, when the upper part is closed over the lower part.

Abstract: In the process wherein a high heat resistance is required for a photoresist pattern such as a manufacture of a TFT active matrix substrate, a super high heat resistant positive pattern is formed using a positive-working photosensitive composition. The pattern forming method of the present invention comprising steps of: applying a photosensitive composition onto a substrate comprising (a) an alkali-soluble resin, (b) a photosensitizer having a quinone diazide group, (c) a photo acid generator, (d) a crosslinking agent and (e) a solvent; then exposing the substrate to light through a mask; forming a positive image by developing and removing the exposed area to light; exposing a whole area of the positive image to light; and post-baking, if necessary. In the case of using 1,2-naphthoquinone-4-sulfonyl compound as the photosensitizer having a quinone diazide group, the above component (c) can be omitted since this compound also functions as a photo acid generator of the component (c).

Abstract: To provide a portable terminal device which has an openable and closable part and an open/close detector which detects opening and closing of the part, where the portable terminal device has a reduced thickness when closed and allows easy position adjustment during assembly. A cell phone equipped with a lower part and an upper part openable and closable in relation to the lower part has a magnet and a magnetic sensor attached to the lower part; and a magnetic plate which is attached to the upper part and leads the magnetic force of the magnet attached to the lower part to the magnetic sensor attached to the lower part when the upper part is closed over the lower part.

Abstract: A method for developing electrostatic latent images formed on an electrostatic image bearing member, particularly by a thin and uniform layer of toner formed on a toner carrying member. In the method, good images can be stably obtained by controlling the gross electric charge per unit area within the range of 3.times.10.sup.-10 to 10.sup.-7 coulomb/cm.sup.2 in terms of the absolute value thereof and the packing density within the range of 0.1 to 0.6 g/cm.sup.3 with respect to the toner layer carried on the toner carrying member at the developing station.

Abstract: A substantially nonmagnetic toner comprising a colorant and a binder comprising a homopolymer or copolymer having a ratio (Mw/Mn) of a weight-average molecular weight (Mw) of a number average molecular weight (Mn) of less than 5.0 is formed in a thin layer on a toner carrying member. The layer of toner is carried to a developing zone at which an image bearing member is disposed to face the toner carrying member with a clearance larger than the toner layer thickness and an electrostatic image on the image bearing member is developed with the thin layer of toner. The toner binder resin preferably comprises a copolymer of a vinyl monomer and an amonoacrylic monomer.

Abstract: A process for production of photoconductive cadmium sulfide is characterized in that a flux is added to cadmium sulfide in an amount of at least 20 weight percent based on the cadmium sulfide, and the resulting mixture is fired at a temperature higher than the melting point of said flux by at least 50.degree.
