Title: Fuel cell
Inventor: TAKECHI TAICHI
IPC: H01M8/24
Filed: 1985-03-30
Abstract: PURPOSE:To enable a fuel cell to be decomposed and reassembled by blocks each consisting of a given number of cell units and one cooling plate without inhibiting the prevention of gas leakage between a separator and a cooling plate by interposing the separator and an expanded graphite sheet between at least one surface of the cooling plate and an adjacent cell unit. CONSTITUTION:After an adhesive 11 is locally applied to a separator 4 and a proper amount of expanded graphite particles 8 are spread over the separator 4 into an almost uniform thickness, the thus formed body is compressed using a press and then is as it is heated thereby making a laminate sheet consisting of a separator 4 and an expanded graphite layer 7. The local application of the adhesive 11 prevents the electric resistance of the laminate sheet from increasing and also facilitates assembly of a fuel cell performed by stacking laminate sheets each of which consists of a unified body. Due to the expanded graphite layer 7 installed between a cooling plate 5 and the separator 4, any gas leakage can be prevented from developing between the plate 5 and the separator 4. Furthermore, a broken cell unit can be very easily replaced by separating the expanded graphite layer 7.

Title: Ink jet recorder
Inventor: MURATA TAKAYUKI
IPC: B41J2/01
Filed: 1989-03-17
Abstract: PURPOSE:To prevent bleeding or the like from occurring due to unsatisfactory fixation in a recording process, and obtain record images with stable quality irrespective of the kind of a recording medium pertaining to recording by varying a relative velocity according to the kind of the recording medium. CONSTITUTION:Each of hold times T1, T2..., TM of a pulse motor 9 represents a stop time during a transfer of a recording head 7 from a position to the next position along P direction at the time of main scanning. For instance, T1 to TM are so set that T1>...>TM. In that case, the hold time is shorter and, hence, the velocity of the pulse motor 9 or the recording head 7 is higher, as TM is approached. Here, TM corresponds to velocity data on actual recording on a recording medium, and T1 to TM-1 correspond to velocity data for obtaining a higher or lower velocity relative to the velocity corresponding to TM. Such tables are prepared in kinds according to the kinds of recording media to be used, thereby enabling appropriate selections. For instance, formation of adjacent dots poor in fixation is carried out at a lower speed, namely, at longer intervals, whereby the problem of bleeding or the like due to failure in fixation can be restrained.

Filed: 1979-06-02
Abstract: PURPOSE: To prevent an abnormal falling of a rubber weir from occurring due to the adhesion of the inside walls of a swelling portion when a rubber weir is leveled, by a method wherein a small-diametered hollow portion is provided in a swelling portion of a rubber weir used for checking sea water or the like, and a fluid material hardenable at normal temperature is filled in the hollow portion to project the latter.  
     CONSTITUTION: A rubber weir is leveled by opening a valve and forcibly discharging a fluid out of the rubber weir by a pump. A fluid material solidifiable at normal temperature is filled into a hollow portion 3 to cause the latter to project into a swelling portion 1a, thereby forming gas passages 8 within the rubber weir when the rubber weir falls. As a result, the inside walls of the swelling portion 1a will not adhere to each other even under water pressure. In addition, since the air passages 8 are stretching longitudinally to a point near a fluid injection port along the hollow portion 3 filled with the solidified fluid material 7, the fluid which would otherwise remain in the rubber weir main body is moved through the passages 8 toward the injection port and discharged.
