Title: Developing device and image forming device equipped therewith
Inventor: FUJITA HIDEKI
IPC: G03G15/08
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To obtain a developing device capable of restraining the scattering of developer while restraining the deterioration of the image quality in a first operable state after a stop state is continued for a long time by making the number of rotations of a part of plural stirring and carrying means lower than a specified number of rotations in a specified time in the first operable state after the stop state is continued for a specified time or longer. SOLUTION: Toner stirring and carrying members 44a and 44b are rotated at a number of revolutions lower than ordinary one so that toner quantity may be reduced in a specified time in the first operable state after the long-term stop of an image forming device. Namely, the ordinary number of revolutions of the toner stirring and carrying members 44a, 44b and 44c in a period other than a specified period is all 24/min. In the specified period, the number revolutions of the member 44c is the same as the ordinary one but the number of revolutions of the members 44a and 44b is set to 1/min. Thus, the toner quantity is reduced to realize the rapid rising of image reflection density.

Title: Intraocular lens
Inventor: NISHI OKIFUMI
IPC: A61F2/16
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To suppress the onset of cataract after wearing intraocular lens. SOLUTION: The intraocular lens consists of an optical part 31 and a loop 32 which is projectingly provided on the outer circumference of the optical part and in which the optical part is positioned by stretching the lenticular capsule of the eye. The cross-sectional shape of the loop is a discontinuous contour with corners. With the intraocular lens attached inside the empty lenticular capsule, the loop 32 of the lens stretches against the inside of the equatorial part of the capsule, which therefore is bent along the corner stretching part of the loop. The epithelial cells on the inner surface of the anterior capsule are prevented from wandering to the posterior capsule side by means of the bent part of the lenticular capsule. As a result, the onset of cataract is effectively prevented.

Title: Reactor for electric car
Inventor: HIRAO SHINZOU
IPC: B60L15/28
Filed: 1979-11-30
Abstract: PURPOSE: To eliminate the inductive interference to the ground signal communications equipment due to the leakaged magnetic flux by dividing the reactor into a plurality of small reactors, connecting them in parallel, and arranging them in a vertical configuration in the car body of the electric car.  
     CONSTITUTION: The reactor is divided into a plurality of smaller reactors. They are connected in parallel and arranged in a vertical configuration in the car body of the electric car. A current is conducted with the polarity so that mutual inductances are cumulative. In this constitution, the space in the room is small. Since the car body serves a role of a magnetic shield, any other additional measure is not required. Since the distance between the reactors FL 1  and FL 2  and the ground signal equipment increases, the inductive interference such as erroneous operation caused by the noises directly reaching the signal equipment due to the magnetic flux leaked from the reactors can be eliminated.
