摘要:
An electrophotographic developer comprising at least one element selected from the group consisting of boron and phosphorus in a content of 0.1 to 100 ppm, which the developer is excellent in flowability and shelf stability, does not give image defects such as occurrence of white stripes and attains almost constant image quality even when the ambient conditions including temperature and humidity fluctuate. A production process of a polymerized toner used in the developer, a production process of the developer, and an image forming process.

摘要:
A control device, which handles a network system in which electronic devices installed in each of multiple rooms are connected via a communication network and each electronic device can perform communication via the communication network, includes: a control unit to selectively set a first control mode in which operation control according to operation input is performed as to a particular single electronic device, a second control mode in which operation control according to operation input is performed in common as to electronic devices installed in the same room, and a third control mode in which operation control according to operation input is performed in common as to electronic devices connected to the communication network, as an operation control mode according to predetermined operation input, and to generate a control command; and a transmission unit to transmit a control command that the control unit has generated according to the control mode.
摘要:
A polyester resin for metal plate coating which contains a dimer acid in an amount of 2 to 10 mol %, as a dicarboxylic acid component and has a weight average molecular weight (Mw) ranging from 70,000 to 160,000. Thus, there can be provided a polyester resin for metal plate coating that has not only excellent film forming capability and corrosion resistance but also excellent impact resistance. Further, there can be provided a resin-coated metal plate excelling in properties, such as corrosion resistance, impact resistance (dent resistance), workability and flavor, and provided, fabricated from the resin-coated metal plate, a metal can and can lid.

Provided is a planetary gear reducer including: a sun gear fixed concentrically to a power input shaft; a plurality of planet gears meshing with the sun gear; a ring gear meshing with the planet gears; a planet carrier configured to support a plurality of planet shafts, each of which is a rotational axis of a corresponding one of the planet gear, and to output revolution of the plurality of planet gears as first power; and a cylindrical support connected to the ring gear, non-rotatable relative to the ring gear, and configured to output rotation of the ring gear as second power. The cylindrical support includes, at one part along the direction of a central axis, a flexible structure which is curved radially inward and has a V-shaped longitudinal section. This configuration improves rigidity and prevents misalignment without increasing the weight of the gear reducer.
