Title: Insulation ohmmeter
Inventor: TAGUCHI MASAAKI
IPC: G01R27/02
Filed: 1990-07-06
Abstract: PURPOSE:To achieve a smaller size and a lower cost by changing over one switch to cover the measurement of an insulation resistance and the checking of an electric discharge of a capacitance component and a power source. CONSTITUTION:When measuring a resistance of an object to be measured, a switch 15 is turned ON to make an enable element (Tr) 12 conduct so that a voltage of a battery 1 is boosted 3 in DC to be applied to the object to be measured through measuring terminals 4 and 5. At this point, a current flowing through the object to be measured runs through a meter circuit 7 through a diode 6 to display a resistance value. Thereafter, when the switch 15 is turned OFF, the Tr 12 is cut and an electric charge stored in a capacitance component of the object to be measured is discharged through a resistance 14. When the switch 15 is turned OFF and the terminal 5 is connected to a terminal 11 for checking, the Tr 12 conducts and a circuit 3 applies a high voltage to the resistance 14, which consumes a specified power. Hence, a power source under such a condition is checked. In addition, the switch 15 is turned OFF to cut the Tr 12 and an AC voltage is measured. This allows one switch 15 to cover all operations thereby achieving a smaller size and a lower cost.

Title: Paper feeder
Inventor: ISHII YASUAKI
IPC: B65H1/18
Filed: 1982-10-13
Abstract: PURPOSE:To stabilize the uppermost sheet level by installing a sheet weight compensation means which applies a large load onto a bottom plate pushing-up mechanism as the sheets in a paper feeding cassette reduce, in a paper in which a paper feed cassette for a copying machine is used. CONSTITUTION:As the number of sheets on the bottom plate 6 of a cassette reduces, a feeler 21 swings clockwise, and when a sensor 22 is operated, a motor 8 is driven by the signal of a level detection means 3, and the sheet is raised through a bottom-plate pushing-up arm 18. A this time, the reduction of load applied onto the bottom-plate pushing-up mechanism 2 which is caused by the reduction or amount of sheets S is compensated by the increase of the amount of flexure of a leaf spring 23. Therefore, the amount of flexure of the spring 23 is little during the time when the bottom-plate 6 is at low position, and the flexure of the spring 23 increases when the bottom plate 6 is raised as the amount of sheets reduces, and a large springy force is applied onto the arm 18, and reduction of load due to reduction of the amount of sheets is compensated. Thus, the sheet level can be maintained correctly.

IPC: F02D45/00
Filed: 1984-08-30
Abstract: PURPOSE:To sense complete combustion at low revolving speed accurately by setting the starting time judgement speed for an internal-combustion engine to three different levels i.e., initial value, an intermediate value which is variable, and a higher value than the after-the-complete-combustion judgement speed. CONSTITUTION:An initial value H1 (700rpm) to continue to be at a high level for preclusion of influence of the first combustion until the starter switch becomes out of effect is set in the starting time judgement speed NSTRT. A variable intermediate value H2 is provided, which applies after the starter switch becomes out of effect and decreases slowly. The a third value is provided, which receives the final level of said variable intermediate value H2 and which shall be higher than the after-the- complete-combustion judgement speed. The sinking rate of the intermediate value H2 shall be lower than the sinking rate of the revolving speed NE of the engine before complete combustion when the starter switch becomes out of effect. Thus the malfunction to judge the first combustion as a complete one at the starting time of an internal- combustion engine can be avoided, and complete combustion at low revolving speed lee sensed off surely.
