Title: Image forming device
Inventor: KATO KOJI
IPC: G03G15/01
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To eliminate dispersion in the line width of images formed at high- potential and low-potential electrostatic latent image parts and to form a good- quality image by setting the absolute value of a potential difference between 1st developing bias potential and intermediate potential to a value smaller than that of the potential difference between 2nd developing bias potential and the intermediate potential. SOLUTION: Since the light intensity of a laser beam used to record an electrostatic latent image has Gaussian distribution, the difference of 50 μm to 60 μm is caused between the line width L1 of the image normally developed at the electrostatic latent image part including the high potential VH and the line width L2 of the image reversely developed at the electrostatic latent image part including the low potential VL. Then, developing bias potential VBH is set lower than in the conventional manner in the case of the 1st image, while it is kept in an equal state to that in the conventional manner in the case of the 2nd image. Besides, the line width L1 of the 1st image is made equal to the line width L2 of the 2nd image. Thus, both of them have the almost equal line width.

Title: Reciprocating internal combustion engine with piston linked with two connecting rods
Inventor: HONDA SHIYOUICHI
IPC: F02F3/28
Filed: 1980-10-25
Abstract: PURPOSE: To keep an inclination of a piston at an angle 0° in an internal combustion engine wherein two connecting rods are linked with an elliptical piston by respectively locating the liked centers of the connecting rods at the centers of gravity exhibited by symmetrically bisecting the piston in a plane figure.  
     CONSTITUTION: Pin bosses 5, 6 are formed on a piston 3 for sustaining a piston  pin 7 which is transversely laid thereon and suspends two connecting rods 8, 9. When a pressure of a buring gas is applied on the upper face of the piston 3 whose bisected left and right parts with respect to a center of the pin are independently out of balance, inclined angles θ at the suspending point (a), (a) of the connecting rods are not zero, which is a cause of a seizure of the connecting rods when their side faces on the larger ends are pressed by a crankshaft 10. For preventing the seizure, the centers of gravity of the left and right bisected parts with respect to the center line A-A of the pin should agree with the points (a), (a). This preventive manner is applicable for a bending moment produced by an inertia force.

Title: Optical demultiplexer
Inventor: YOKOTE SHOHACHIRO
IPC: G02B6/28
Filed: 1984-07-19
Abstract: PURPOSE:To demultiplex projection light equally to plural projection fibers by converting low-order projection light from an incidence fiber to a high-order mode through a tapered high-order mode conversion part which decreases in diameter gradually, and then reconverting the light to the low-order mode through a tapered low-order mode conversion part which increases in diameter gradually. CONSTITUTION:When projection light 5 in low-order mode which is projected from the incidence fiber 2 is incident on a mixing rod 1, the mixing rod 1 projects the light 5 on the low-order mode conversion part 3 while converting it to the high-order mode gradually because the conversion part is tapered at an about 6:7 taper ratio. The power distribution of the projection light 5 at the connection part between the mixing rod 1 and low-order mode conversion part 3 is uniform, so the low-order mode conversion part 3 transmits the light while performing the gradual conversion to the low-order mode so as to convert the high-order mode projection light 5 to the propagation mode of projection fibers 4, and enters the light into respective projection fibers 4 equally. Consequently, the low-order mode projection light is demultiplexed to the respective projection fibers 4 equally even if the projection light 5 from the incidence fiber 2 is in low-order mode.
