Title: Original size detector
Inventor: MIZOMICHI KAZUYUKI
IPC: G03G15/04
Filed: 1991-01-28
Abstract: PURPOSE:To accurately detect an original size even when the floating state of an original is changed by wind pressure at the time of closing a platen cover in an original size detecting device which detects the original size based on the changing state of the output of an original sensor at the time of closing the platen cover. CONSTITUTION:The output of the original sensor 1 is compared with a threshold from a threshold generation circuit 3 in a comparison circuit 2, and supplied to the input port of a CPU 5 through an integration circuit 4. The output of 1st and 2nd platen sensors 6a and 6b which detect the opening of the platen cover is also supplied to the input port of the CPU 5. The CPU 5 detects the original size based on the changing state of results obtained by comparing the output of the original sensor 1 in the different opening of the platen cover with the threshold, and the threshold is made high when the opening of the platen cover is small.

IPC: G05F3/30
Filed: 1986-01-18
Abstract: PURPOSE:To eliminate the influence of an increase or decrease of a constant current source by generating the emitter current of an npn transistor Tr by a current mirror circuit composed of two pnp Trs and a resistance and supplying a constant current to the npn Tr. CONSTITUTION:An npn Tr 10 has its base connected to a resistance 7 and the collector of an npn Tr 8 and a Tr 1 has its emitter connected to the constant current source 2 and its collector and base short-circuited. Further, a resistance 12 is connected between the collector-base connection point of the Tr 11 and a low potential terminal 4. Then, the base of a Tr 14 is connected to the base-collector connection point of the Tr 11 and the collector is connected to the collector of a Tr 10. Further, the emitter of a Tr 13 is connected to the constant current source 2, the base is connected to the collector of the Tr 10 and the collector of a Tr 14, and the collector is connected to the low potential terminal 4. In this constitution, a stabilized output voltage is determined by the sum of the voltage drop across the resistance 7 and the base- emitter voltage of the Tr 10. Consequently, an increase of the constant current source 2 is absorbed by the Tr 13, so the base-emitter voltage of the Tr 10 becomes stable.

Abstract: PURPOSE:To prevent abnormal combustion due to seal oil leaking out into a gas injection valve, by performing intermittent gas operation, in which gas fuel is injected for a fixed period in every predetermined number of cycles, when operation is switched from an oil operation mode to a gas operation mode. CONSTITUTION:In a combined fuel Diesel engine using oil fuel and gas fuel, after its operation is switched from oil operation to gas operation, the engine reduces the oil fuel as pilot fuel to a predetermined quantity alpha while controls an injection quantity of the gas fuel to a value Q-alpha subtracting the quantity alphafrom a required quantity Q. And in this switching process, the engine intermittently injects the gas fuel only for one cycle in every predetermined number N of cycles while holds an injection quantity of the oil fuel to the quantity Q in cycles, when the gas fuel is stopped, during a fixed period T. In this way, abnormal combustion due to seal oil leaking out into a gas injection valve can be reduced.
