IPC: F16L25/02
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To block the corrosion by the current owing to the generation of a potential difference, by insulating between a bronze valve and a stainless steel pipe of a water supply equipment. SOLUTION: This pipe coupling consists of a hollow coupling main body 110 whose one end is connected to a saddle snap tap; a box nut 114 screwed in to the other end of the coupling main body 110; and pipe drawing preventive means 117 and 118 set in a circular recess 116 between the tapered inner peripheral surface 114a of the box nut 114, and the outer peripheral surface of a stainless steel pipe 5. While the coupling main body 110 is injection molded by a synthetic resin material, the box nut 114 is also injection molded by a synthetic resin material, and in this case, the coupling main body is injection molded integral with the box nut main body by setting a head-cut conical core 120 made of a stainless steel, on the tapered inner peripheral surface of the box nut 114.

Title: Image forming device using potential division developing system
Inventor: ISHII MASAYOSHI
IPC: G03G15/01
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To restrain fringe development caused by the sweeping of fog by forming an electrostatic latent image which is not developed on a background part separated from an image part on the trailing edge side of the image part with respect to the rotating direction of a developing roll. SOLUTION: Image forming operation is performed by forming a latent image by an exposure means 10 after uniformly eletrifying a photoreceptor 1 by an electrifier 2. At such a time, an image signal 11 is recognized and the electrostatic latent image which is not developed is formed at a separate position on the trailing edge side of the latent image by a negative image pattern adding device 12. The latent image by potential division developing is developed with two kinds of toner by two developing machines 3 and 4. In a pretransfer electrifier 5, the electrifying polarity is adjusted because the electrifying polarities of two colors of toner with which the image is developed are different. Then, two colors of toner is transferred to transfer paper 6 by a transfer machine 7. Thereafter, the toner is melted and fixed on the paper 6 by a fixing machine 8.  Then, the residual toner is recovered by a cleaner 9. Thus, the fringe development caused by the sweeping of the fog is restrained.

Title: Sliding contact
Inventor: ITO HIDETAKA
IPC: H01R39/18
Filed: 1990-05-11
Abstract: PURPOSE:To obtain low contact resistance which is stable over a long period even under atmosphere with high humidity by setting a composition containing graphite powder, tin powder or a mixture of tin powder and silver powder, and a binder of a thermosetting synthetic resin in a specific weight ratio. CONSTITUTION:A sliding contact is molded and cured from a composition containing 95 to parts of graphite powder, 5 to 20 parts of tin powder or a mixture of tin powder and silver powder, and less than 15 parts of a binder of a thermosetting synthetic resin. The metallic powder may be tin powder alone or contain silver powder in an amount equal to or less than that of the tin powder. When part of the tin powder is thus replaced by silver powder a variation in contact resistance is further improved as compared to the one only tin powder is used. However the rate of increase of the cost is heightened when the amount of added silver powder exceeds that of the tin powder.

IPC: G02B7/34
Filed: 1994-05-09
Abstract: PURPOSE:To obtain an in-focus photography result even if a photographer performs shutter releasing operation during the movement of a subject by continuously driving a lens driving means without any stop even when exposure operation is started. CONSTITUTION:Once a defocusing quantity Dn is calculated, the driving means is driven by the quantity and at the end of the driving, storing operation is started. When it is decided that a body moves, the driving is performed uniformly at a constant speed throughout the period of storage calculation, and driving as to a driving quantity for correction accompanying the body movement. Namely, lens movement is performed even in the storage period, correction is required correspondingly, but easy since the movement in the storage period is constant in speed. Driving only for tracking needs not be so fast, so the influence on a time measurement error is small. Consequently, there is no restriction on exposure time for in-focus exposure, an in-focus photograph can be taken whenever the shutter is released, and the release responsiveness is superior.
