Title: Centrifugal dryer
Inventor: IKEDA TOMOHIKO
IPC: D06F33/02
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal vibrations due to unbalance of the washing at the time of a drying operation. SOLUTION: A weight 60 is attached to a drum 54 so that the drum may have an eccentric load. As the washing is dehydrated, the weight thereof is decreased, but since the weight of the weight 60 remains the same, before the dehydration much of the washing is placed near the position 180 deg. opposite to the weight 60 and after the dehydration is balance is made. If items of the washing different in water content are placed improperly in a biased manner in the drum 54, since the position of the eccentric load is changed before and after the dehydration, before the start of the dehydration step, a swinging operation is performed so that the items of the washing containing a large amount of water may be moved to the bottom side and the items of the washing containing a small amount of water may be moved to the upper side.  As a result, when items of the washing are distributed, items of the washing whose weight will be decreased greatly will be placed near the position L2 that is 180 deg. opposite to the weight 60. Thus, after the dehydration, the position of the eccentric load can be prevented from changing and the balance can be kept easily.

Title: Drum device
Inventor: SUZUKI NORIO
IPC: G03G21/00
Filed: 1988-12-27
Abstract: PURPOSE:To reduce the unevenness of rotation of a photosensitive body which has an adverse effect on image quality by providing a fly-wheel inside the hollow drum. CONSTITUTION:A driving motor 18 drives a gear 14b provided on a member 14 by means of a driving gear 17 attached to the driving motor 18 so as to rotate the photosensitive drum 11. The fly-wheel 12 arranged inside the photosensitive drum 11 has large moment of inertia and increases the movement of inertia of the drum 11. Therefore, the unevenness of rotation of the drum 11 which has the adverse effect on the image quality is reduced. The fly-wheel 12 has high rigidity and stress caused by the load of the fly-wheel 12 is restrained from applying to the photosensitive drum by integrally bonding the fly-wheel 12 with members 13 and 14. Thus, the moment of inertia of the drum is increased without a large space, thereby miniaturizing an equipment.

Abstract: PURPOSE:To prevent malfunction after a load is turned off by connecting a power supply line of an amplifier circuit to a power line of a capacitor provided in a monostable multivibrator and used for counting a prescribed time. CONSTITUTION:A power supply line of an amplifier circuit 11 is connected to a power supply side of a capacitor C2 provided in a monostable multivibrator 12 and used for counting a prescribed time for time limit operation. Thus, while a load energized by a command tone is operated only for a prescribed time within a limit time, the amplifier circuit 11 is forcibly deenergized for a prescribed time till the capacitor C2 is charged after the transit to a load stop (non-operation) attended with the end of discharge of the capacitor C2. Thus, an input to the monostable multivibrator 12 is suppressed for a prescribed time. Thus, malfunction due to noise or the like after the stop of the load is surely prevented.
