IPC: G02B13/04
Filed: 1998-08-17
Abstract: PROBLEM TO BE SOLVED: To form an excellent image by effectively correcting magnification chromatic aberration in an inverted telescopic image-forming optical system with a back focus longer than a focal length. SOLUTION: Sequentially from an object side, a lens group is configured of a 1st lens group with a negative refractive power and a 2nd lens group with a positive refractive power. When a distance Bf from the last face of the entire lens system up to an image-forming plane is made longer than the focal length f (f<Bf), and also an optical member DOE having a diffraction plane with a negative refractive action (fdoe<0) is formed on the 1st lens group, and when the focal length of the diffraction plane is expressed as fdoe, this image-forming optical system is configured so as to satisfy the condition of 50f<|fdoe|<500f. The negative optical member DOE is excellent in the partial dispersion, and effectively corrects magnification chromatic aberration.

Title: Resin insulated bearing
Inventor: MIZUTANI MAMORU
IPC: F16C33/64
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To prevent any crack in a resin layer from occurring by forming this resin layer ranging from an outer diametral surface of an outer ring to a chamfer and an end face, and continuing the chamfer and the outer diametral surface smoothly with a radiused face or tapered face. SOLUTION: A resin layer 12 uses synthetic resins such as, for example, polyphenylene resin, polyamide resin, urethane resin, acryl resin, epoxy resin, etc., and it is integrally formed as one body in an outer ring 11 by means of injection molding. Then a chamfer 11c of the outer ring 11 and an outer diametral surface 11a are smoothly continued by a radiused surface R1. A radiused r2 of this radius surface R1 is fairly larger than the radius r1 of the chamfer 11c. Thus, the chamfer 11c and the outer diametral surface 11a are smoothly continued by the radiused surface R1 of the large radius r2, whereby any edge in a boundary portion is eliminated, so that any stress concentration attributable to the occurrence factor of a crack in the resin layer 12 is hard to be produced. Therefore any possible crack in this resin layer is prevented from occurring.

Title: Valve mechanism for internal combustion engine
Inventor: KONNO TSUNEO
IPC: F01L13/00
Filed: 1986-10-17
Abstract: PURPOSE:To simplify the structure of an oil pressure supplying circuit, by varying the setting load to a return spring in each connection-switching-means and providing a means which switches and supplies more than one stages of oil pressure to an oil pressure supplying passages, which is commonly connected to each connection-switching-means. CONSTITUTION:When an engine is on operation at a, say, medium speed, the oil pressure of an oil pressure supplying source 46 in an oil pressure supplying means 45 is regulated by a regulator on one side to a comparatively low oil pressure and is supplied to each oil pressure chamber 29a or 29b. Then, in the first, connection-switching-means 21a, a piston 23a is moved to the first rocker arm (7) side. Thus, the first and second rocker arms 7 and 8 are connected to each other and are driven by a high-speed cam 5. On the other hand, in the second, connection-switching-means 21b, the movement of a piston 23b is prohibited by a return spring 25b. Thus, the second and third rocker arms 8 and 9 remain uncoupled. Accordingly, an inlet valve on one side opens or closes in correspondence to the movement of the high-speed cam, while the inlet valve on the other side opens or closes in correspondence to the movement of the second, low-speed cam.
