Abstract:
A connector includes an insulator, into which a thin plate-like object is removably insertable, including contact insertion grooves and partition walls positioned therebetween and contacts inserted into the contact insertion grooves, each of the contacts including first and second contact portions spaced from each other to allow the thin plate-like object to be inserted therebetween, and including a connecting portion connecting the first and second contact portions. At least one of the first and second contact portions contacts the thin plate-like object when inserted into the insulator. A hollow portion having a greater width than the contact insertion grooves is formed in each partition wall to superimpose part of each contact as viewed in a contact arranging direction, and the partition walls prevent each hollow portion from being communicatively connected with the contact insertion grooves.

Abstract:
An apparatus for manufacturing toner is provided which includes a pulverizer for pulverizing a material into particles, a classifier for classifying the particles by size, a discharging path for discharging the particles from the pulverizer to the classifier, a returning path for returning relatively coarse particles among the classified particles from the classifier to the pulverizer, and a handling unit for handling particles. A method for manufacturing toner is also provided which includes pulverizing a material into particles in a pulverizer, discharging the particles from the pulverizer to a classifier via a discharging path, classifying the particles by size in the classifier, and returning relatively coarse particles among the classified particles from the classifier to the pulverizer. The handling unit is provided on at least one of the discharging path and the returning path, and includes a mechanism for preventing accumulation of the particles using airflow.
Abstract:
A connector to which an object is to be connected, includes an insulator having at least one contact support groove, and at least one contact which is fixed to the insulator by being inserted into the contact support groove, the contact being contactable with the object after the object is inserted into the insulator. The insulator includes at least one holding portion formed as one of a recess and a through-hole, which is communicatively connected with the contact support groove, and the contact includes a locking protrusion, which comes into engagement with the holding portion to hold the contact to the insulator when the contact is inserted into the contact support groove.
Abstract:
A connector includes an insulator having an accommodation space into which an object to be connected to the connector is removably insertable, the object being a thin plate having a pair of engaging recesses at opposite side edges thereof; at least one contact fixed to the insulator, the object being connected to the contact upon insertion into the accommodation space; and a pair of resilient engaging protrusions, each having an engaging portion, which are resiliently deformable away from each other in a plane in which the object lies, the engaging portions being respectively engaged in the pair of engaging recesses of the inserted object. A distance between the engaging portions of the pair of resilient engaging protrusions in a free state is smaller than a width of an insertion end of the object which is to be inserted into the accommodation space.
