Filed: 1993-04-01
Abstract: PURPOSE:To obtain a desired characteristic while arithmetic time is shortened and a design change is simplified by respectively feeding back state quantity of a filter, which is directly obtained, and a state quantity by estimation from the input/output of a controlled object. CONSTITUTION:The controlled system 1 can be controlled by a control signal yf corresponding to a control objective value (r) and it outputs a signal (y) showing the controlled state. A state observing unit 3 outputs the state quantity xf of the controlled objecti1 based on the state signal yf and the output signal (y). The filter 2 outputs the control signal yf based on the signal (r) of the control objective value and outputs the self state quantity xf. Feed back gains ks 41 and kf 42 feed back state quantities xs and xf, which the state observing unit 3 and the filter 2 output, as against the signal (r) of the control objective value inputted to the filter 2. The state observing unit 3 needs to estimate only the state quantity of the controlled object 1. Thus, arithmetic quantity in the state observer 3 can be reduced and the design change can easily be executed.

Title: Developing method
Inventor: HANEDA SATORU
IPC: G03G13/08
Filed: 1983-06-02
Abstract: PURPOSE:To obtain an image which can reproduce faithfully fine lines and dots or varying densities, etc. and has high image quality by spheroidizing the magnetic carrier particles of a two-component developer. CONSTITUTION:The magnetic carrier particles of a two-component developer are spheroidized and the particles having 5-30mum average grain size are used to perform development in an oscillating electric field. The spheroidization of the magnetic carrier particles contributes to an improvement in the stirring property of the toner and carrier, the conveyability of the developer and the electric charge controllability of the toner and to the prevention of the flocculation among the toner particles or between the toner particles and the carrier particles. The uneven toner image is prevented by reducing the average grain size of the magnetic carrier particles so that the development at a high density is made possible. Since the spherical carrier particles are formed together with the material that can be stuck on recording paper of a resin, etc., the carrier particles sticking on the recording paper are prevented from being fixed by heat or pressure and from damaging the surface of an image carrier. The image having high image quality is thus obtd.

Filed: 1990-04-12
Abstract: PURPOSE:To realize low frequency operation or static operation by constituting a pre-charge transistor(TR) with a MOSFET whose acceptor is led to a channel, and making the current as small as the circuit leakage current flow at the OFF time of it. CONSTITUTION:In this dynamic logical gate which is constituted of a logical block 1, the pre-charge TR 8, a deciding TR 2, and a NOT gate 3, and in which both gates of the pre-charge TR 8 and the deciding TR 2 are connected to a clock terminal, the pre-charge TR 8 is constituted of the MOSFET whose acceptor is led to the channel. Accordingly, at the OFF time, the gate is not non-conductive, but the current as small as the leakage current of the circuit flows, and during a deciding period, an output node is charged so much as to cancel the leakage current of the circuit. Thus, even if the deciding period is prolonged, namely, even if operating frequency becomes low, the voltage of the node is not dropped and malfunction is never caused.
