Title: Switching regulator
Inventor: MUROTA KAZUAKI
IPC: H02M3/155
Filed: 1991-02-07
Abstract: PURPOSE:To limit a current when an input voltage is high and to control a duty when the voltage decreases in a step-down type switching regulator. CONSTITUTION:An output voltage V0 of a switching regulator is monitored by an error amplifier OP, its output and an output of a triangular wave oscillator OS is input to a PWM comparator COMP1, and an ON duty of an output transistor T1 is controlled by the output of the comparator COMP1. When an input voltage V1 is high, a maximum ON duty of the transistor T1 is limited by a fixed voltage applied to a DTC terminal of a DTC comparator COMP 2. When the voltage V1 decreases, an output side of a comparator COMP3 becomes a high level, a transistor T3 is turned ON, and a limit of the ON duty is released.

Abstract: PURPOSE:To suppress a shape of the device from becoming a large size, to raise the suction efficiency, and to execute an efficient operation of a fan by driving an adsorbing device for absorbing a material to be transferred to a carrying device by a driving device for driving in image carrying body, etc. CONSTITUTION:A fan 27 of an adsorbing device for adsorbing a form carried by a carrying belt to a carrying belt 10 is driven by a main motor 15 for driving a photosensitive drum 9 and a pair of fixing rollers 11, etc. Accordingly, since it is unnecessary to provide separately a motor for driving a fan 15, a space for providing a motor is not required, and it can be suppressed that the device constitution becomes a large size. Also, since a motor for driving the fan 27 is not required, the fan 27 can be provided in the vicinity of the carrying belt 10, therefore, the suction efficiency can be raised. Moreover, since the fan 27 can be held so as to be freely rotatable by one piece of ball bearing, an efficient operation of the fan can be executed.

Title: Combustion control device for burner
Inventor: NISHI TAKAHIRO
IPC: F23N5/06
Filed: 1985-01-31
Abstract: PURPOSE:To enable to easily perform a processing as well as to improve the flow rate change of fuel gas to a temperature change by a method wherein a spring to energize to the open direction of the valve is provided on one side of the valve chamber, and at the same time, a temperature-sensing chamber is abutted on the other side of the valve chamber and an operating stick is set up in such a way as to be able to vertically move through the valve chamber and the temperature-sensing chamber. CONSTITUTION:When the atmospheric temperature is risen by the combustion of the burner and riss, a temperature-sensing element 7 is made to expand and pushes and operating stick 10 up, whereby one end of that operating stick 10 pushes a valve 2 up against the repulsive force of a spring 5. Accordingly, as the interval between the valve 2 and a seating part 6 narrows and the flow rate of the fuel gas decreases, the amount of combustion of the burner reduces and is controlled in the temperature- drop direction, while when the atmospheric temperature reversely drops, the temperature-sensing element 7 is made to shrink, whereby the valve 2 descends while pushing the operating stick 10 down by the repulsive force of the spring 5. Accordingly, as the interval between the valve 2 and the seating part 6 widens and the flow rate of the fuel gas increases, the amount of combustion of the burner augments and is controlled in the temperature-rise direction.
