Title: Image forming method
Inventor: YASUDA SHINICHIRO
IPC: G03G15/20
Filed: 1991-05-30
Abstract: PURPOSE:To improve transferring efficiency and to simplify and miniaturize a device. CONSTITUTION:This is an image forming method constituted of an electrostatic charging stage for electrostatically charging a photosensitive body 1, an exposing stage for exposing the photosensitive body 1, a developing stage for forming a toner image by attaching toner 10 on the photosensitive body 1, a transfer stage for transferring the formed toner image on a recording medium 16 such as a recording paper, etc., and a fixing stage for fixing the transferred toner image on the recording medium 6. In this method, capsule toner is used as the toner 10 and the transfer stage and the fixing stage are simultaneously executed on the surface of the photosensitive body by using the preheated recording medium 6. Thus, the toner image formed on the surface of the photosensitive body at the developing stage is simultaneously transferred and fixed on the recording medium whose surface is heated by preheating, so that the transfer and fixing stages are drastically simplified and a heat radiating device is drastically simplified and miniaturized because the fixing is performed at a low temperature. Furthermore, since an independent transfer stage is not necessitated, the adjustment of the resistance of the recording medium such as the recording paper, etc., becomes unnecessary.

IPC: G03G15/04
Filed: 1983-08-25
Abstract: PURPOSE:To form an image on a copy form at a correct position and improve operativity and image quality by using a line sensor to recognize the setting state of an original, and correcting an optical system on the basis of the recognition result. CONSTITUTION:The line sensor 25 of 512-bit X2 constitution is provided behind a half-mirror 21 to make an X-directional scanning by the movement of the optical system and an Y-directional scanning with the clock of the sensor 25, and the obtained video output is converted from analog to digital in sequence. A pre-scanning is made prior to copying operation, and the sensor 25 reads corner parts P1, P2, and P3 of the original to calculate bias fillings theta1 and theta2 from their distances x1 and Y1. Those bias fillings theta1 and theta2 are used to drive pulse motors 30 and 31, correcting pulses of the optical system. Therefore, even if the original shifts slightly, a copy is taken at a correct position as if the original were set to a reference line, and image quality is improved.

Title: Digital signal regenerator
Inventor: HARIKAE SHIYUNJI
IPC: G11B5/09
Filed: 1978-12-13
Abstract: PURPOSE: To reduce the peak shift and then to eliminate the demodulation error by providing the filter featuring the fixed group delay time in the course of the regeneration system of the digital signals.  
     CONSTITUTION: LPF5 is installed between pre-amplifier 4 which amplifies the regenerated digital signals and limiter 6 which gives the limitation to the output amplitude of the digital signal. This LPF5 features the fixed delay time within the frequency bands 1fW2f of the signal as well as the gentle properties of under 12dB/ octave for the amplitude within the range of 2fW6f, and at the same time such sudden attenuation properties of over 12dB/octave is secured for the amplitude of over 6f. As a result, no delay distortion is given when the regenerated signals pass through LPF5 along with the transient response not lowered so much. Accordingly, the regenerated signal featuring good S/N is obtained, and the peak shift caused by the piling of the high frequency noise can be reduced to eliminate the demodulation error.

Title: Method and system for adjusting mean current passing load and manipulator type remote controller applying the same
Inventor: JIYAN PIEERU RIGAAESURAN
IPC: H02M3/156
Filed: 1990-06-15
Abstract: PURPOSE: To easily and quickly select a response curve matching a condition as much as possible by preliminarily storing correspondence previously set between the numeric value of control variable information and the numeric value of logic average currents. CONSTITUTION: The real number value of information is constantly measured by an initial control information α. Whatever value the control information α, is, a correspondence I=F (a) corresponding to the numeric value of currents is stored without any error. Then, a logical cycle rate (pwmn) is calculated for the signal of a cut wave voltage having a constant frequency by combining each numeric value I of the currents with those numeric values according to a preliminarily decided replacement function indicating desired response curve. The logical value of this cycle rate is transmitted to an adder 9, and the corrected value of the cycle rate is supplied from the output of the adder. A control system 3 of the currents passing the load preliminarily decides the cycle rate (pwm) within the load.  Thus, the range of a control operation can be limited to a difference between the real number value and the logical value of the cycle rate, and the high speed operation can be attained without any response.
