Abstract: PURPOSE: To evade the fixed 1:1 connection among plural CPUs and CRT devices serving as the man-machine interfaces of a system which performs the centralized supervisory and control of a plant, etc., via those CPUs and also to prevent increase of the CRT operating burden for every CPU. CONSTITUTION: The CPU 2 (2-1, 2-2) and the CRT devices 1 (1-1, 1-3) are connected together via a bus type LAN 11. When the CPU 2 transmit the state data collected from a plant onto the LAN 11, each of devices 1 receives the state data from the LAN 11 and converts them into the data on a screen display variable part. Then the device 1 takes out its own stored data on a screen display fixed part and combines together the data on both variable and fixed parts to display them on a screen. Thus any of CRT devices 1 can display the collected data on both CPUs on its screen, and the CPUs have not to produce the screen display data. This reduction of burden can eliminate the increase of burden of the LAN communication and the response speed is secured for the screen display.

IPC: G03G15/20
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To improve the fixing quality at both ends in a direction perpendicular to a paper carrying direction and to shorten the rise time in the case of performing fixation to a short-width paper in a fixing device. SOLUTION: Inductance coils 50 are connected in parallel with margin width parts (parts exceeding maximum paper passing width) 46 and 48 taking temperature gradient parts at both ends of a fixing heater 44 into consideration so as to provide a switching circuit 55 for a direct circuit 57 and a rectifier circuit 58. When temperature at the margin width parts 46 and 48 rises, the rectifier circuit 58 is selected. Since an AC current from a commercial power source 52 is rectified, the current bypasses the inductance oil 50 side. Therefore, the rise of the temperature at the margin width parts is restrained, an the fixing quality at both ends of the paper is improved. When the rectifier circuit 58 is selected and the fixing device is started up, the resistance value of the heater 44 is lowered. so that the power supplied to the heater 44 is increased and the rise time is made short.  It is used in a ceramic roller where a fixing roller itself is set as the heater 44.

Title: Cross modulation preventing circuit for radio control use receiver
Inventor: YAMAZAKI TADAO
IPC: H04B1/10
Filed: 1985-04-17
Abstract: PURPOSE:To prevent a cross modulation under a strong electric field and a malfunction caused by suppressing the sensitivity, by controlling the attenuation quantity of an attenuator which is provided on a radio control use receiver, by a sub-circuit of other system. CONSTITUTION:Under a strong electric field in which across modulation is generated, an amplification by an FET Q3 and a transistor TR Q4 is executed in order to control an object signal. A detecting output is supplied to an attenuator 6 from a collector of a PNP TR Q5, and a forward voltage is generated by diodes D1, D2 for constituting the attenuator 6 through a resistance R. When the forward voltage exceeds a value corresponding to a forward on-voltage of about 0.5V, the diodes D1, D2 become a conducting state, and a high frequency current flows to an earth or a power source side through both the diodes D1, D2 and is attenuated. Capacitors C1, C2 have a small capacity of 2-5pf, therefore, a bad influence caused by coupling of each of a tuning circuit T1 and a matching transformer T2 is prevented, and also an attenuation effect can be increased.
