Title: Development apparatus
Inventor: MIYASAKA TORU
IPC: G03G15/08
Filed: 1993-03-17
Abstract: PURPOSE:To surely prevent toner from leaking out of both ends of a developing roller for a long duration. CONSTITUTION:A developing roller 13 is so composed as to have a structure where both ends of the roller are wrapped with a thin sheet-like seal member 19. The sheet-like seal member 19 rolls on the developing roller 13 due to dynamic friction between the development roller and itself. Consequently, sure contact is provided between the developing roller 13 and the thin film and as long as the dynamic friction coefficient is constant even in the case in which the seal member 19 wears, the material rolls on the developing roller 13 at constant force. The seal member 19 seals and prevent the toner layer at both end parts on the developing roller 13 from spreading and dropping. Since the pressure of the wrapping of the seal member 19 can be maintained properly by previous adjustment of the dynamic friction coefficient, excessive rolling is prevented and the driving torque of a development apparatus is suppressed to a low level.

Title: Device for detecting and processing vibration and loose part
Inventor: HASHIMOTO YUUJI
IPC: G01M99/00
Filed: 1980-05-02
Abstract: PURPOSE:To enable the total capacity of wave memory to be decreased, by using an envelope detecting means which follows the rising period of a detected signal and has a smooth time constant at falling period and obtaining the wave-form whose peak position and peak value are the same as those of the detected signal. CONSTITUTION:Instead of a detector wherein an integrater is used, is employed the envelope detecting means which has a small time constant at the rising period of the signal and has the large time constant at the falling period. For example, a diode 51 is connected in series, a capacitor 52 and a resistor 53 are connected in parallel, and a four terminal circuit is constituted. Since the capacitor 52 is rapidly charged through the diode 51 at the rising period of the signal, the output wave-form follows the rising of the signal. At the falling period, the amplitude decreases in response to the time constant determined by the CR. Therefore, the envelope wave-form whose peak position and peak value are not different from those of the detected impact signal is obtained. Thus, sampling in the wave memory can be delayed, and the capacity can be decreased.
