A developing device including a developer containing magnetic toner grains and includes a main pole for development disposed in a sleeve. Flux density generated by the magnetic pole in a direction normal to the surface of the sleeve outside of the surface has an attenuation ratio of 50% or above. The toner grains have a weight mean grain size of 6.0 μm to 8.0 μm while the toner grains having grain sizes of 5 μm and below occupy 40% to 80% of the entire developer. The toner grains have magnetization strength of 10 emu/g to 25 emu/g in a magnetic field of 5 kOe or magnetization strength of 7 emu/g to 20 emu/g in a magnetic field of 1 kOe. The toner grains reduce toner scattering and image defects despite that they are magnetic, thereby implementing ultrahigh resolution.

A charger includes a charging member for charging a desired member. The charging member is made up of a conductive support and a film formed on the support and formed of a substance having negative electron affinity. The film affects electrostatic electron discharge at a low voltage and can therefore charge the desired member more efficiently than a substance having electron affinity. In addition, the charger does not affect discharge and therefore reduces ozone.

An object of the invention is to provide a thermocouple having a high response speed without receiving mechanical damages such as bending and curving even when it is used in a high-speed fluid. The invention provides a quick-response thermocouple for high-speed fluid in which a sheathed thermocouple having a small outer diameter that is formed by housing, in a metal sheath, a positive-side thermocouple filament and a negative-side thermocouple filament embedded within a powder of an inorganic insulating material, and by forming a temperature sensing point at a tip portion thereof by bonding the tips of the positive-side thermocouple filament and the negative-side thermocouple filament together at the tip portion thereof, is inserted in a protective tube having a large outer diameter so that the tip portion is exposed, in which a portion of the sheathed thermocouple that is exposed from the protective tube is inserted in a protective cylinder having a bottom cover with a hole on a tip side through which the sheathed thermocouple is inserted and having a plurality of through windows, the tip of the sheathed thermocouple is slightly exposed from the bottom cover of the protective cylinder, and the bottom cover of the protective cylinder and the sheathed thermocouple as well as the protective cylinder and a lower portion of the protective tube are welded.

A method is provided for manufacturing a film formation member having a dividing wall provided on a substrate to form a plurality of partitioned sections with a film being formed within each of the partitioned sections by discharging a predetermined amount of liquid within each of the partitioned sections. The method includes identifying a position of at least one of the partitioned section as a partitioned section with nonuniform liquid affinity among the partitioned sections, and discharging the liquid over a wider discharge range inside the partitioned section with nonuniform liquid affinity than a discharge range inside a partitioned section other than the partitioned section with nonuniform liquid affinity.

An electro-optical device includes a plurality of pixels arranged on a substrate. Each of the pixels includes a plurality of EL light-emitting elements that are disposed on the substrate and are connected in series. Each of the EL light-emitting elements includes a first electrode, a luminescent layer, and a second electrode that are disposed in a thickness direction of the substrate, and each of the EL light-emitting elements has a characteristic of emitting light in response both to a forward applied voltage and to a reverse applied voltage. The first electrodes or the second electrodes of neighboring EL light-emitting elements of the plurality of EL light-emitting elements are coupled to each other, so that the plurality of EL light-emitting elements are connected in series.

A method for manufacturing a display device, such as an organic EL display device including at least a first electrode film, a light-emitting film, and a second electrode film over a substrate, with less use of photolithography, includes patterning at least one of the films by laser etching.

A combined thin film magnetic head includes a magnetoresistive reproducing head part and an inductive recording head part. The magnetoresistive reproducing head part is defined between a lower shielding layer and a merged core layer. The inductive recording head part is defined between the merged core layer and an upper core layer and is configured to specify a track width for the recording head part by providing the upper core layer in a localized region W.sub.2. A method of fabricating the magnetic head includes steps of forming an etching-protective layer on a gap layer so as to provide an exposed region W.sub.1 left uncovered which is larger than the localized region W.sub.2 in which the upper core layer is to be finally confined, depositing the upper core layer over the entire surfaces thereof, and etching the upper core layer so as to finally confine the etched upper core layer in the localized region W.sub.2. In a preliminary process, the merged core layer is formed to have an elevated part at a location corresponding to the localized region, and an insulating layer is deposited around the elevated part of the merged core layer, before the gap layer is deposited entirely over the elevated part and the localized region.

An apparatus for preparing infusions such as coffee in different forms includes a sealed container in which water is heated so that it can be used either as hot water or steam, a water tank and a heating element for heating the contents of the container. Water in the tank can flow into the container through a conduit containing a check valve. Four conduits have outlets at the top of the container. One of them is connected to an infuser and is adapted to transport hot water. Another conduit is adapted to transport steam which may be used for preparing a cappuccino-like drink or for preheating a receptacle. The other two conduits are for removing high pressure steam from inside the container, one of them having an outlet near the bottom of a subtank which is built as a part of the water tank.
