IPC: G03G15/20
Filed: 1988-10-07
Abstract: PURPOSE:To accomplish excellent fixation by stopping or decelerate the rotation of a heat roller after holding the leading edge of a recording paper between the heat roller and a backup roller forming deflection so that the recording paper comes into contact with the heat roller, conveying the recording paper while holding the deflection and performing the fixation. CONSTITUTION:The recording paper 2 is guided by a recording paper guiding plate 8 and a side roller 9 and the leading edge of the paper 2 is held between the heat roller 3 and the backup roller 5. At the time of holding the leading edge of the paper 2 between them, the rotation of the heat roller 3 and the backup roller 5 is stopped or decelerated. At such a time, since the side roller 9 rotates and the guiding plate 8 exists, the deflection 10 occurs upward on the recording paper 2 and an abutting part 11 is generated. The recording paper 2 is conveyed while it keeps the abutting part 11 with the deflection 10. Therefore, a time when the recording paper 2 is in contact with the heat roller 3 can be made longer. Thus, the excellent fixation can be accomplished though the set temperature of the heat roller 3 is lowered.

Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To avoid brackets from lowering impact absorbing performance at collision, in an automobile provided with the brackets for supporting a stabilizer on the front end of a subframe fitted to the sideframes of a main frame. SOLUTION: Left and right a pair of brackets 24 are projectingly provided facing front on the front end face of a subframe 13 fixed to the front parts of left and right sideframes LL, LR extending in the longitudinal direction of a vehicle body, and a stabilizer 23 of which both ends are connected to left and right suspension arms 20L, 20R, is supported with the upper faces of the brackets 24. Because vertically penetrating openings 29 are formed on the rear parts of the brackets 24 and the axes L of the brackets 24 slant left and right relative to the longitudinal direction of the body, when a load due to collision is applied from the front side, the brackets 24 easily buckle.
