Title: Large capacity stacking device in classification of paper sheet
Inventor: SUDOU KIMIHISA
IPC: B07C3/08
Filed: 1985-09-27
Abstract: PURPOSE:To make a paper sheet stackable without using an exclusive stacking box, by incorporating the designation of large capacity into a feed code forming process. CONSTITUTION:Mail appearing in an inlet of a feed passage 1 forms an address to a feed code memory 7 by an address conversion device 4 from the result of a judging device 3. The memory 7 selects one feed code from this address and gives the said code to a tracking controller 8. And, this tracking controller 8 makes the feed code correspond to the mail and guides it to a stacking box desired. Here, when a fullness schedule of a certain stacking box is detected by a fullness schedule detector 5, a large capacity designation memory 6 is made to refer to, whereby the presence of large capacity designation is checked. Should it be the stacking box designated with the large capacity, the feed code of the designated stacking box is read out, and the area concerned to the feed code memory 7 corresponding to the stacking boxy that the fullness schedule is detected is replaced with the feed code of the large capacity designated stacking box.

Title: Fuel cell assembly body with electrolyte transferring member
Inventor: CHIYAN BAN CHI
IPC: H01M8/00
Filed: 1982-12-06
Abstract: PURPOSE:To obtain a fuel cell assembly body including an electrolyte transfer means which secures communication of electrolyte with an electrolyte matrix by placing the electrolyte matrix between a first and a second gas-separating plate which have a first and a second process gas path and are fused to a first and a second electrode respectively. CONSTITUTION:Electrolyte supplied to a cell 1 through a hole 22, is transferred to the end 19b of a channel 19 through holes 15a, 10e and a slot end 23a. The channel end 19b is closed to a direct path penetrating a separating plate 18. Therefore, electrolyte passes along the length of the channel 19 and communicates with a matrix 10b after passing through a slot 23, thereby filling the matrix 10b with the electrolyte. Excess electrolyte leaves the channel 19 at its end 19a through a penetrating hole 21. As illustrated in the figure, a cell stack is constituted by stacking cells 1, 2 and 3 in that order. Owing to the above constitution, after electrolyte is supplied from an electrolyte supply source into the end 33b of a channel 33 by the time excess electrolyte is discharged from the stack through the penetrating hole 21, the matrix of each cell can be filled with the electrolyte.
