Abstract: PURPOSE:To prevent erroneous data read by arranging a data output terminal of an interchangeable lens in the leading position in the interchangeable lens setting direction and preventing a data input terminal in the camera body side from being brought into contact with another terminal in case of setting of the interchangeable lens. CONSTITUTION:A data output terminal JL1 of the interchangeable lens provided with a lens circuit consisting of a C-MOSFET is arranged in the leading position in the interchangeable lens setting direction of an arrow Z. That is, when a seat plate contacting face 5 of the interchangeable lens and a seat plate face 11 of a camera body 21 are brought into contact with each other and the interchangeable lens is rotated in the direction of the arrow Z, a seat plate claw 13 and a bayonet claw 7 are engaged with each other to lock the interchangeable lens in a prescribed position, and at this time, the terminal JL1 is slided on terminals JB5, JB4...JB1 of the seat plate face 11 in order and is stopped in the position of the data input terminal JB1. Thus, erroneous data is not transmitted to the side of the camera body 21 because the terminal JB1 is not brought into contact with the other terminals JL2-JL5 in case of lens setting.

Title: Image forming device
Inventor: TANIGAWA KOICHI
IPC: G03G15/01
Filed: 1992-05-29
Abstract: PURPOSE:To prevent irregularities in a transfer image with a simple constitution by making an intermediate transfer body for transferring an image formed on a 1st image carrier to be a medium resistance elastic roller. CONSTITUTION:When the toner image on a photosensitive drum 1 is transferred-to an intermediate transfer roller 20, the potential of a non-image part is different from the potential of the toner image part, and when the potential of a core bar 21 as a reference, the potential difference between the non- image part and the core bar 21 is larger than the potential difference between the toner image part and the core bar, so that a transfer current flows to the non-image part more as compared with the toner image part. This inclination is remarkably generated when the resistance value of the intermediate transfer roller is low, on the contrary, when the resistance value is high, an electrical field generated by a bias supply 61 is too small, so that the intermediate transfer itself is damaged. Thus, the medium resistance roller whose resistance value is within 10<5>-10<11>OMEGA.cm, preferably, 10<7>-10<10> case of using an elastic body having such a volume resistance value, a proper transfer current value can be set by impressing the voltage of 2 to 5kV on the core bar 21.

Title: Method of operating zinc-bromine battery
Inventor: JINNAI KENICHIRO
IPC: H01M12/08
Filed: 1984-08-08
Abstract: PURPOSE:To prevent any decrease in the efficiency of a zinc-bromine battery which might be caused after completion of charging due to deterioration of the zinc of the negative electrode by removing the liquid electrolyte from the cell when charging is completed and then washing the negative electrode by ion exchange water with a temperature almost equal to that of the electrolyte before the washed cell is stored until it is discharged. CONSTITUTION:After charging is completed, the liquid electrolyte is removed from the cell and then the interior of the cell is washed by ion exchange water with a temperature almost equal to that of the electrolyte during charging. Thus washed cell is then stored until it is discharged. It is preferable that washing condition is at most 0.4ml/min of water per unit electrode area of one cell for at most 1min. By the means mentioned above, zinc deposited in a negative electrode 6 at the end of charging can be stored as it is without being influenced by the electrolyte until discharge is started. Accordingly, it is possible to greatly reduce the self discharge of zinc.
