摘要:
The present invention relates to an inverter driven lamp arrangement. The arrangement provides for the sensing of both lamp voltage and current. The arrangement also provides for a large current during times of low voltage and a small current during times of high voltage. The sensing of lamp current is done by a current detector that is connected to a resonance circuit whose output is applied in signal form to a lamp start control circuit. The resonant circuit is a series connected resonant circuit composed of a choke coil and a first capacitor. This series connected arrangement is further connected in series with a second non-resonant capacitor. Also the arrangement includes circuitry to gradually reduce the frequency of the inverter just after the lamp starts.

A toner supply device advantageously applicable to a full color copier has a plurality of supply units each being associated with respective one of developing units incorporated in the color copier. The supply units each is selectively engaged with or disengaged from associated one of the developing units by a toner supply path, facilitating the supply of toner and maintenance work.
摘要:
A developing device and a toner supply device for a color copier and others. A toner supply conduit adapted to transport fresh toner from the toner supply device is disposed in a developer chamber of the developing device. The wall of the toner supply conduit is perforated to form inlet openings and outlet openings for a developer which is stored in the developer chamber and contains toner and carrier. The inlet openings of the conduit are located in the vicinity of a predetermined position where the developer is to be separated from a developer conveying member. Provided in the toner supply conduit is a transport member for mixing and transporting the fresh toner and the developer which is introduced through the inlet openings. At least a part of the transport member is made of a magnetic material, and at least a part of the magnetic part is situated within the reach of a magnetic force of a magnet which forms a part of the developer conveying member. The toner supply device comrises a toner tank, and a feed member for feeding the fresh toner out of the toner tank. The frequency of operation of at least one of the toner feed member and other operable members which are associated with the toner feed member is counted. The end of toner is displayed when the frequency counted reaches a predetermined one representative of a decrease of toner in the toner tank to zero or to below a predetermined amount.

Provided is a multilayer adhesive sheet which enables easy separation between an adhesive layer and a die attach film during the pick-up even in cases where an acrylate ester copolymer is used in the die attach film, thereby making the pick-up work of semiconductor chips after the dicing easy. The multilayer adhesive sheet comprises a base film, an adhesive layer that is disposed on one surface of the base film, and a die attach film that is disposed on an exposed surface of the adhesive layer. The adhesive that constitutes the adhesive layer contains: (A) a (meth)acrylate ester copolymer; (B) an ultraviolet polymerizable compound; (C) a multifunctional isocyanate curing agent; (D) a photopolymerization initiator; and (E) a silicone polymer.

A container is provided that is used as a container permitting easy transfer into another container without spilling of contents at the time of work of refilling. The present invention relates to a container that is fitted in a container body of tubular shape having an open end, a bottom part and a side wall and that transfers contents into a preservation container. This container has: a funnel component (201) provided with a funnel (220) whose diameter decreases from a larger opening side toward a smaller opening side and provided with a plurality of ribs (228) that extend radially from the center of an opening part (222) on the smaller opening side of the funnel (220) so as to bridge a part with another part of the inner surface of the opening part (222) on the smaller opening side; and a container body.
