Patent JP-H08306374-A (JP)
Title: Fuel cell device
Inventor: SHUDO HISANOBU
IPC: H01M8/04
Filed: 1995-05-09
Abstract: PURPOSE: To prevent the breakage or reduction of service life of a fuel cell by performing differential pressure control to the highest value of gas pressure at a fuel electrode to which gas pressure at an oxidizer electrode faces among differential pressure at respective points in the whole plane of the fuel cell. CONSTITUTION: At a point 4, for example, in the whole plane of a fuel cell 11, differential pressure between both of a fuel electrode and an oxidizer electrode is detected by differential pressure detection parts 1-4, and each detected differential pressure is inputted to a minimum value selecting part 5. At the minimum value selecting part 5, the minimum value is selected among those by the differential pressure detection parts 1-4, and the selected minimum value is transmitted to a differential pressure control part 6 as the differential pressure between both electrodes. At the differential pressure control part 6, the differential pressure between both electrodes is controlled to make the transmitted minimum value equal to a set value.  Under such control, the differential pressure becomes positive at all the differential pressure detection points by the differential pressure detection parts 1-4, while the minimum value is the set value. Gas pressure at the fuel electrode thus exceeds gas pressure at the oxidizer electrode facing it in the whole plane of the fuel cell 11, thereby differential pressure control with the smallest differential pressure can thus be provided.

Abstract: PURPOSE: To enable multi-color printing onto a container having a constructed part by a method wherein stamping rolls are arranged in a rotating direction from upstream in order of the radial length at the region to be printed of the container having a circular crosssection. CONSTITUTION: At printing, a container 1 is conveyed with a timing screw 35 and, at the same time, a rotary drum 10 is rotated. With an urged first stamping roll 31, the inks on a shoulder part stamping part and on a cylinder part stamping part are transferred to a shoulder part-fixed transferring surface part and to a cylinder part-fixed transferring surface part. At this case, a movable transferring surface part 20 is pressed by the roll 31 so as to be pushed in the interior of an annular groove of the transferring drum 10 in order to be flush with the shoulder part-fixed transferring surface part and the cylinder part-fixed transferring surface part. Next, after the ink on an urged second stamping part is transferred to a transferring piece, which is projected beyond the transferring drum 10 with a spring 25, the ink on the transferring drum is transferred to the shoulder part and the cylinder part of the container, which is moved so as to rotate on its axis by a guide 34.

Filed: 1993-05-13
Abstract: PURPOSE:To realize miniaturization by acquiring the rotational information of a disc through the use of reflected light while eliminating the need of zero point adjustment of the disc and the mechanical section at the time of assemblage. CONSTITUTION:A drive means 3 rotates a disc 2 recording basic information including at least one piece of information related to the angle, the direction or the number of revolution and a light irradiating means in an optical head 4 irradiates the surface of the disc 2 with light energy.
