Title: Printer

IPC: G03G15/06
Filed: 1979-12-26
Abstract: PURPOSE: To obtain a developer free from uneven latent images according to the exposure of nonimage parts by reciprocatively moving the one-component type magnetic developer in the gap of a predetermined size between a developing roller and a photosensitive drum opposing thereto by an alternating electric field.  
     CONSTITUTION: A gap between a developing roller 3 and a photosensitive drum 1 opposing thereto is so selected as to be larger than the adhered layer thickness of the one-component magnetic developer adhered to the roller 3. If a predetermined alternating magnetic field is generated by an alternating electric field applying means 8, the developer reciprocatively moves in the gap space. This causes the adhesion of the developer on the image part of the drum 1 to be increased by the reciprocating developing material without affected by the edge effect, and the uniform developing is accomplished irrespective of the uneven potentials of the image part. Hence, the good quality latent image by the exposure of the nonimage part is formed, and the exposure of the nonimage part is performed with small quantity of light.

Title: Control method of differential restricting device of vehicle
Inventor: NISHIKAWA SEIICHI
IPC: B60K17/346
Filed: 1988-07-07
Abstract: PURPOSE:To improve the durability of a differential restricting device and the braking performance of a vehicle by restraining the differential operation between front and rear wheels when there is a difference between braking forces applied to the front and the rear wheels during driving and maintaining the differential restraining value at the specified value. CONSTITUTION:It is determined whether a difference DELTAFB between the braking forces of front and rear wheels is over a reference value DELTAF1 or not. When the force is increasingly applied to a parking brake or a foot brake, the DELTAFB is increased and if is over the DELTAF1, the differential operation is executed between the front and the rear wheels and the differential operation restraining force is set to the specified value. As a result, the locking limit of wheels to which a higher braking force is applied than the other is increased; the braking performance is improved; the excessive power circulation is prevented, making the differential restraining device more durable.

Title: Wind power generating device
Inventor: HAYASHI CHIKAYUKI
IPC: F03D11/02
Filed: 1994-07-22
Abstract: PURPOSE:To make noise lower and to improve reliability by detecting electric resistance among the input and output shafts and casing of a traction drive speed increasor, and when each resistance signal is less than a fixed value in a computing means, stopping control for setting an output to a fixed value, and lowering the number of revolutions. CONSTITUTION:When wind speed increases, and the torque of a wing 1 therefore becomes above a certain value, slippage begins between the rollers of a traction drive speed increasor 2a, and an oil film between the sliding rollers is brocken to cause direct contact between them. The electric resistance among input and output shafts 4, 5 and a casing 7 becomes zero. When each output on voltmeters 15a, 15b on input and output sides becomes below a fixed value, a computing element receives these resistance signals, and control for setting the output of a generator 3 to a fixed value is stopped, and a control signal for lowering the number of revolutions is outputted to lower the number of revolutions of the wing 1. When the number of revolutions of the wing 1 lowers, and the slippage between rollers stops, and the oil film is therefore formed, the resistance signal is issued as before. Thus the safety operation of the wind power generating device a becomes possible, and the noise from the above device is lowered and its reliability is improved.
