摘要:
An electrode material for an electric double layer capacitor which comprises spherical particles (A) comprising an electrode active material and a thermoplastic binder wherein said spherical particles (A) have a sphereness degree of not larger than 20% as defined by the equation: sphereness degree (%)=(Ll−Ls)×100/La where Ls is short axis diameter, Ll is long axis diameter, and La=(Ll+Ls)/2. The particles (A) is made preferably by a process comprising mixing together the electrode active material with the thermoplastic binder in a solvent to form a liquid dispersion; and then, spray-drying the liquid dispersion. An electric double layer capacitor having the electrode made from the electrode material is characterized as having low internal resistance and high capacitance.

摘要:
Receiving a switching control signal output from an Wireless tag reader/writer, a switching control means sequentially switches feeding points of an antenna unit, and the Wireless tag reader/writer is made to retain all information from information of an Wireless tag that initially communicates to information of an Wireless tag that finally communicates for each feeding point.
摘要:
A read and write box of a wireless tag reader and writer according to and embodiment of the invention has an open end and a closed end. Multiple envelopes each having a wireless tag at the end are inserted through the open end into the read and write box. The read and write box has a first read antenna and a second read antenna on the upper surface. The first read antenna detects wireless tags in a write area at the closed end; and the second read antenna detects wireless tags outside the write area. A write antenna is disposed at the closed end of the read and write box. The write antenna writes data to wireless tags. A step is formed on the lower surface of the read and write box in such a manner that the bottom of the write area is lower than the bottom adjacent to the open end so that the ends of the envelops align in the vicinity of the closed end.
摘要:
A method for producing an electrode for electric double layer capacitors is disclosed which comprises: a step of mixing a particulate elastomer and a carbonaceous material with each other in a powdery form, thereby obtaining a powdery mixture; and a step of dry-forming the resultant powdery mixture, thereby forming an electrode layer. With this method, an electrode which enables to form a high-capacity electric double layer capacitor can be produced by simplified steps with high productivity.
