Filed: 1982-03-02
Abstract: PURPOSE:To obtain printing outputs of specified density even if temp. changes, by compensating the change in the characteristics of a photoreceptor occuring in the change in temp. with increased electrode voltage. CONSTITUTION:A photosensitive drum 1 is charged electrostatically with an electrostatic electrifier 2, and is exposed with the output images to be printed by an exposure part 3, whereby latent images are formed thereon. Toners of - are stuck on these latent images of + by a developing device 4, so that the latent images are made visible. The visible images are attracted onto paper 11 by a transfer charger 5, and the visible toner images on the paper 11 are heated with a fixing device 8, by which the images are fixed strongly on the paper. If a change in temp. arises in the drum 1 or around the same, the change in temp. is detected with a temp. detecting element 16, and the higher voltage is applied on the electrode of the electrifier 2 by a converter 13 according to said change; therefore, the surface potential on the drum 1 is maintained roughly constant irrespectively of the change in temp. The quantity of the toner to be stuck on the latent images from the device 4 is thus maintained constant and the printing density on the paper 11 is maintained roughly uniform.

Abstract: PURPOSE:To aim at protection for a light driving device and a motor, by using one motor in common, while energizing coild with high torque and stopping the motor when both degrees of low torque energizing for light-up angle adjustment and high torque energizing for retract driving are beyond the specified time. CONSTITUTION:A signal showing energizing or unenergizing for relay coils 72a and 71a of a motor drive 70 is impressed and when the energizing is the case, a transistor 91 turns to OFF whereby charging for a condenser 93 gets starting. After turning to OFF, if t1 elapses, voltage of the condenser 93 goes beyond reference voltage V1, and output of a comparator 95 comes to H. Then, timer over signals I=H are impressed on a transistor 77, and a coil 73 is energized with current whereby output torque of a motor 40 for short-circuiting a resistor 78 goes up. Next, when passing t2 from OFF, voltage of the condenser 93 goes beyond reference voltage V2, making output of a comparator 94 turn to H, and a transistor 96 turns to ON, then time over signals n=L are impressed on each of diodes d8, and d9. With this constitution, a continuous rating current for energizing these coils 72a and 71a is cut off, thereby protecting the motor 40 as it comes to a stop.

Abstract: PURPOSE:To reduce the working load on a piston thereby to lessen measuring errors by testing a flowmeter with a gas of a high pressure at an intermediate and a high pressures and impressing the pressure also to a rear chamber of the piston. CONSTITUTION:A testing pressure P1 (=P2) is first set. A piston 3 is moved with a speed corresponding to a flow velocity (u), and a piston 4 is driven with a speed slightly faster than the speed corresponding to the flow velocity (u), whereby a pressure loss DELTAP is known. By use of the obtained DELTAP, the speed of the piston is corrected to a speed corresponding to a flow velocity u'=P2.u/(P2-DELTAP) wherein P2 is the pressure of the upper stream of a flowmeter 16 measured by a pressure sensor 26. The instrumen tal error of the flowmeter 16 is started to be measured. When the piston 3 is moved to the lowest position and the piston 4 comes to the uppermost position, electromag netic valves 21, 23 are opened, while electromagnetic valves 17, 19 are closed. A servo motor of driving devices 9, 10 is rotated in a reverse direction, so that the piston 4 is advanced (lowered) and the piston 3 is retracted (raised). Then, after the pressure is adjusted as above, testing is conducted by flowing a gas in the direction of a broken arrow.

Abstract: PURPOSE: To prevent any wheel lock from taking place in a reflux type anti-lock brake, by setting a hydraulic pressure in a reservoir chamber determined by a spring load when the volume of the reservoir chamber becomes the maximum, to less than the lock hydraulic pressure set as a hydraulic pressure under which wheel lock may take place on a road surface of a comparative high frictional coefficient. CONSTITUTION: When a hydraulic pump fails during execution of anti-lock brake control, a reservoir piston 17 compresses the first spring 26 of a comparatively small spring constant in a reservoir 4 so that it may move to come in contact with a spring receiving member 28 and thereafter compresses the second spring 271 of a comparatively large spring constant so that a reservoir piston 17 may move to the side for increasing the volume of the reservoir chamber 16. When the volume of the reservoir chamber 16 becomes the maximum, the spring load exhibited by a spring energizing means 201 is set in such a way that the hydraulic pressure in the reservoir chamber 16 determined by the spring load is set to less than the lock hydraulic pressure set as a hydraulic pressure under which wheel lock may take place on a road surface of a comparatively high frictional coefficient. Therefore it becomes possible to prevent the wheel lock from its generation.
