Abstract: PURPOSE:To enable the light of a light source to be recognized not only from right above, but also laterally by making the side of a display member facing the light emission source transparent and forming a convex part which transmits and scatter light on the display side of the display member. CONSTITUTION:The side of the display member 1 which faces the light emission source is made transparent and the display side of this display member 1 is made convex so that light is transmitted and scattered. Namely, the display member 1 is a light transmissive and scattering member which has a plane photodetection surface 1a on the light source side, so when the light of an LED 6 is made incident on this photodetection surface 1a through a reflector 7, the incident light is scattered in the transmissive and scattering member, so that the whole of the display member 1 emits light. Consequently, the whole of the part projecting from an operation part cover 4 is seen illuminating. Consequently, even when the display member 1 is lighted from right below by using a light source such as the LED 6 having relatively strong directivity, the illumination of the display part 1 can be recognized not only from right above as shown by an arrow A, but also laterally as shown by B.

Filed: 1988-05-11
Abstract: PURPOSE:To improve rolling fatigue life characteristic by dip-forming a layer of high carbon chrome steel containing specified percentage of C, Si, Mn, Cr, P and S with a thickness larger than the specified value on the face of a carbon steel rolling bearing, which comes into contact with rolling bodies. CONSTITUTION:A layer of high carbon chrome steel containing 0.50-1.20% of C, 0.05-1.60% of Si, 0.15-2.50% of Mn, 0.25-3.00% of Cr, not more than 0.025% of P and not more than 0.05% of S, with 0.05-2.50% of Mo added as needed, is dip-formed on the face of carbon steel rolling bearings such as ball bearings and roller bearings, which come into contact with rolling bodies. The thickness of the dip-formed layer is made larger than D/20 for the diameter D of the rolling body since peeling tends to easily result when the thickness is less than D/20. The layer of high carbon chrome steel is rapidly cooled and its crystals are atomized by the dipping process. Without requiring any other specific fabrication or treatment, adequate abrasion resistance is obtained with quenching and tempering after machining and forming. The rolling fatigue life characteristic can be thus easily improved.

Title: Contact switching device
Inventor: UOTOME RIICHI
IPC: H01H50/56
Filed: 1992-05-01
Abstract: PURPOSE:To prevent the energy increase in a drive means with contact fusing prevented and tripping force improved, by making a movable contact to be tilted in the width direction of a movable contact plate spring to a fixed contact. CONSTITUTION:When a movable contact 3 makes a contact with a fixed contact 7, since the movable contact 3 is tilted to the fixed contact 7 by the tilt of a movable contact plate spring 1, both the contacts are brought into contact while arcs are generated between the nearest part of the movable contact 3 to the fixed contact 7 and the fixed contact 7. More pushing of the movable contact 3 by driving force causes pressing force in a proceeding direction and sliding force at right angle to the pressing force because of the tilt of the movable contact 3, the part melted by the arc is slid by this sliding force to be separated without being fixed, and a part where an arc is not generated is also brought into contact to be in the state of being turned on. In this case, about 10% of the drive force is applied as the sliding force to lower welding probability. On the hand, tripping force can be improved because the movable contact 3 is separated after sliding with respect to the fixed contact 7.
