Title: Circuit to limit beam current of cathode ray tube
Inventor: DIETERLE FRANZ
IPC: H04N5/57
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To make an image bright without causing any danger to a transformer in the case of an extreme load by acting a control circuit to reduce a beam current when a temperature sensor of the transformer senses a higher temperature than a prescribed temperature. SOLUTION: A voltage U3 is higher than a voltage U4 in a normal state and a point (c) is decoupled from a point (b) with a diode D1 biased reversely. When a temperature of a transformer Tr, that is, a temperature of a ferrite core 8 and a resistor R2 rises, the resistance of the resistor R2 is decreased to decrease the voltage U3. When the temperature exceeds a prescribed temperature, the voltage U3 is smaller than the voltage U4 and the diode D1 is forward- biased. Then part of a current from a resistor R3 flows through the diode D1 that is forward-biased and no longer flows to a high voltage winding 5. This depicts it that a threshold level of a beam current limiter is gradually reduced and transmitted power is reduced as desired.

Title: Resetting system for electronic equipment
Inventor: IGUCHI SHIGEKI
IPC: G06F1/24
Filed: 1986-05-07
Abstract: PURPOSE:To prevent the system runaway caused by the drop of the internal power supply voltage by producing a reset signal when the voltage of a back-up internal power supply is reduced less than a prescribed level. CONSTITUTION:When the voltage of a back-up internal power supply 18 is reduced less than a prescribed level, a comparator 19 sends a signal of a high level to a line l4 at a time point t1. The signal of the line l4 is delayed by a prescribed time through a delay circuit 20 and supplied to the terminal at one side of a reset signal producing circuit 21. Receiving the delayed signal, the circuit 21 transmits a reset signal, the inverse of RS. Thus the CPU runaway is never produced despite an abnormal drop of the power supply 18.

Title: Image recording device
Inventor: TANAAMI HIDEYUKI
IPC: B41J19/76
Filed: 1989-04-26
Abstract: PURPOSE:To make possible the output of a recorded image of high quality without irregularities in the transport amount of a recording medium by detecting the irregularities in the transport amount in the subscan direction of recording paper and correcting a specified transport amount in the subscan direction based on the detected results. CONSTITUTION:It is determined how far a paper feed roller 48 has turned from a reference position by rotating the roller 48 and setting it at a reference position prior to paper feed when printing is performed and counting the number of drive pulses during paper feed and printing of data assigned to a recording head. Then a fractional part is printed and deflections generated until a current position is determined are summed based on deflection data in ROM 19 when paper is fed for the printed fractional part. If the sum is 'plus', the number of drive pulses to a pulse motor 13 is reduced by an increase in the paper feed amount as it is larger than a designed amount. If the sum is 'minus', the number is increased by a decrease in the paper feed amount. This control prevents the irregularities in the transport amount of a recording medium when paper is fed for the fractional printed part.
