Title: Surface finishing method of stainless steel plate containing cr
IPC: C23G1/08
Filed: 1992-03-13
Abstract: PURPOSE:To make both surface appearance and corrosion resistance excellent by restoring corrosion resistance deteriorated in the case of mechanically abrading a stainless steel plate by selection of base material and pickling after abrasion. CONSTITUTION:A stainless steel plate 1 incorporates an easily oxidative element such as V, Ti, Zr, Ca and rare earth elements which are low in oxygen contents and sulfur contents and have oxygen affinity larger than Cr. The stainless steel plate 1 is mechanically abraded by using an abrasive belt having grain size of No.100 or more. At this time, a passive film 2 formed on the surface is removed and the easily oxidative element is preferentially oxidized. Thereby a comparatively porous oxidative film 3' and a dense and thin oxide layer 6 are formed. The oxidative film 3' is removed by pickling after abrasion. A passive film 2' incorporating the easily oxidative element is formed on the surface of the stainless steel plate 1. The easily oxidative element is preferentially oxidized in a time of mechanical abrasion. An insufficient layer of Cr is inhibited from being formed on the surface part of the stainless steel plate 1.

Title: Lens with fresnel lens for vehicular lamp equipment
Inventor: SAKAKIBARA KOICHI
IPC: G02B3/08
Filed: 1988-04-11
Abstract: PURPOSE:To contrive an reduction in working cost by letting angle fresnel steps be formed so as to be cut, and thereby letting each fresnel step be continuously arranged in parallel with the circumferential direction along the pitch base line. CONSTITUTION:Fresnel steps 3 are formed in parallel along the pitch base line C of a lens surface divided in each fresnel step design section 2 in a circular arc form. When the pitch P of the pitch base line C is made small (P=0.3 through 1.5mm), the height H of each fresnel step 3 can be made low. In the fresnel step design section 2 in a circular arc form which is divided in the radial and co-axial directions on a lens member 1, the section is divided with respect to both the direction where each light beam crosses the fresnel steps 3 and the tangential direction so as to let each two dimensional design be worked out for letting the fresnel steps 3 in three dimensional structure be formed so that the refraction of light beam can be easily controlled. This constitution thereby eliminates failures due to improper forming and the like.

Title: Fixing structure of connector hood for cable
Inventor: NISHIYAMA TOMOAKI
IPC: H01R13/64
Filed: 1991-04-23
Abstract: PURPOSE:To prevent erroneous insertion and make it possible to mount connectors highly densely by forming an open part and a recessed part in a connector installation panel able to slide, and forming an extruded part corresponding to the recessed part in a connector hood for a cable. CONSTITUTION:An I/O connector 5 and a connector 2 for cable connection are connected by inserting a connector hood 1 for a cable into an open part 8. After the connection of the connectors 2 and 5, an extruded part 3 is located in the back side of a panel 7. When the panel 7 is slid, the extruded part 3 and the panel 7 overlap to contact each other while differing from the positions of a recessed part 4 and the extruded part 3, so that the hood 1 is prevented from pulling out. That is, the extruded part 3 prevents error insertion and also the connector from pulling out. Error insertion of a plurality of the same connectors is prevented by altering the positions of the extruded part 3 and the recessed part 4 for each connector. Moreover, since the space for fastening a screw becomes unnecessary, highly dense mounting of connectors becomes possible.
