Title: Toggle type die clamping apparatus
Inventor: YAMADA AKIO
IPC: B29C45/66
Filed: 1987-06-29
Abstract: PURPOSE:To improve workability and safety by arranging a die clamping stroke sensor and a tact timer to set changing point before stopping point and changing low pressure to high pressure at this changing point. CONSTITUTION:A rack 16 is arranged to a piston rod 12 for the die clamping cylinder 11 and a potentiometer 18 is fitted to an engaged pinion 17. The die clamping stroke sensor is constituted of a rack 15, the pinion 17 and the potentiometer 18. The tact timer (vibrator), which outputs tact signal series (reference pulse signal) at the prescribed interval, is arranged in a CPU 26 in a control part 19. At the stopping point at the time of die-clamping under low pressure, this position is detected and operated based on signals of the meter 18 and tact timer, and the fixed value is added with the CPU 26, to find the clamping point from the low pressure to the high pressure. As the setting of the changing point is automatized, the workability and the safety of the die clamping are improved.

Title: Image forming device
Inventor: KOSUGE AKIO
IPC: G03G15/16
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution and to prevent a failure such as speed irregularity or vibration caused by a joint from being generated by using a belt constituted only by joining plural sheets. SOLUTION: The belt is produced to have such constitution that two sheets S1 and S2 are joined to be deviated in a longitudinal direction (rotating direction of a belt) by proper amount so that the joining positions (c) and (d) of both end faces in the longitudinal direction of the sheets may be different between the adjacent sheets S1 and S2. The belt produced in such a way, the joint part does not project to the front side surface and the inner side surface of the belt. By joining wide surfaces utilizing the joining surface equivalent to the deviation of the sheets S1 and S2, action that the mutual joining of the end faces is reinforced is obtained, so that joining force gets strong and durability is enhanced. Since two sheets S1 and S2 are joining to be plane not only at the ends but also all over the periphery, the very strong joining force is obtained.

IPC: G04B27/02
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To judge the gearing state of a hand adjusting member to hand driving gears by an appearance. SOLUTION: When the fitting part 20d of a hand adjusting member 20 reaches a position touching the coming out prevention fitting part 22b of a cover 22, a correction string 20c reaches the position gearing to hand driving gears 24. As the correction string 20c and the hand driving gears 24 properly gear, a knob part 20b stops at the same position as the level difference part 22e of the cover 22.
