Title: Differential pressure fitting device
Inventor: SHIMIZU SHIGEFUMI
IPC: F24F7/007
Filed: 1987-10-26
Abstract: PURPOSE:To stabilize pressure difference between inside and outside a room and to accurately detect pressure by fixing a fitting plate which have many small holes at positions that do not face an external pressure detection part to a fitting device main body. CONSTITUTION:The fitting plate 7 is fixed to the fitting device main body 3 while abutting on one flank. Many holes 8 which are small enough not to allow an insect, etc., to enter the inside are formed in the fitting plates 7 at the positions which correspond to a recessed part 6 and do not face the outdoor pressure detection part 5. When the fitting device is fitted on a wall part by the fitting plate 7, an outside wind is blown to the fitting plate 7 strongly and possibly, but the small holes 8 do not face the outdoor pressure detection part, so dynamic pressure does not exert a large influence. Consequently, the pressure difference between the pressure of a part A inside the room and the pressure of a part B outside the room is stabilized and the pressure is accurately detected.

Title: Image forming device
Inventor: MURAKAMI KOICHI
IPC: G03G15/04
Filed: 1988-10-28
Abstract: PURPOSE:To prevent image drift due to the misregistration of an original by controlling an image forming means according to deviation detected by a detecting means. CONSTITUTION:When an inlet sensor 3 or 22 detects an original and copying instructions are started, an inlet stopper solenoid 21 or 29 is turned on, and a DF motor 19 normally rotates to convey the original. Monitoring continues until the original arrives at a DF outlet sensor 13. When the original arrives at the DF outlet sensor 13, the DF motor 19 is turned off to start the reverse rotation of the DF motor 19, and clocks from a sensor 20 are counted after the original passes by the DF outlet sensor 13. When the counted value of the clocks reaches S, the DF motor 19 is turned off, a break is made to control in the way that the entire belt 7 of the DF motor is completely stopped. Moreover, clocks from the sensor 20 are counted simultaneously after the DF motor 19 is turned off. Namely, clocks are counted in order to absorb the shift of the stop position due to the variance of machine's inertia and changes with elapsed time. Thus, images can be registered correctly.
