Title: Laser welding method for thin sheet
Inventor: YANAGIDA YASUHIDE
IPC: B23K26/21
Filed: 1985-04-19
Abstract: PURPOSE:To decrease the generation of the cracks in a weld zone by specifying the ratio between the melting diameter and fusion width of the nugget in the weld zone at a specific value or below thereby setting welding conditions. CONSTITUTION:The nugget is welded to the sealing part of a gimbal 2 of a thin sheet spring and a spacer 5 by laser beam welding to form the weld zone 1. The irradiation energy density of laser light is so controlled in this stage that the ratio between the melting diameter B on the surface of the gimbal 2 and the fusion width A of the spacer 5 attains <=1.4. The cracks D generated in the laser weld zone 1 increase sharply when the ratio B/A of the diameter B and the width A exceeds 1.4. The generation of the cracks D in the weld zone 1 is thus prevented by adopting the laser welding condition under which the value of the B/A is specified at <=1.4.

Title: Variable range light measuring apparatus
Inventor: MOMIYAMA KIKUO
IPC: G03B7/099
Filed: 1984-04-24
Abstract: PURPOSE:To make it possible to continuously change a light measuring range, by the titled apparatus having a miniaturized and simplified structure constituted so that a light receiving lens is constituted of a light pervious elastomer and the shape thereof is deformed to change the refractive power of said lens. CONSTITUTION:A light measuring apparatus is constituted of a light receiving lens 2 formed of an elastomer and a light receiving element 3 and the image B of a subject is almost formed onto the surface 3a of the light receiving element 3 by the lens 2. The elastomer is selected from one largely deformed by small pressure, for example, such as silicon rubber. The lens 2 is pressurized by a cylindrical container 4 having circular opening parts 4a, 5a and a movable part 5. When relatively small pressure is applied to the lens 2, the radii of curvature of the lens surfaces 2a, 2b become small and the focal distance of the lens 2 becomes long and, therefore, a light measuring range becomes narrow. When relatively large pressure is applied, the radii of the lens surfaces 2a, 2b become relatively large and the focal distance of the lens 2 becomes short and, therefore, the light measuring range becomes relatively wide.

Title: Method and equipment for controlling non-stage transmission
Inventor: PATORITSUKU RARUDEI
IPC: F16H59/00
Filed: 1995-04-07
Abstract: PURPOSE: To avoid frequent repeated shift change by identifying a running condition excessively large relative to a running resistance in which a rapid change in transmission gear ratio is present so as to suit a selected transmission gear ratio to a running resistance with traction force. CONSTITUTION: A group of transmission gear ratios preadjusted before a transmission gear ratio control part 27 is operated are filed in a memory. During the operation, a transmission gear ratio preadjusted by an automatic function part 32 or a manual function part 33 is selected, and adjusted by a transmission through an adjusting function part 31. Next, if an identifying device 40 identifies before a shift down is requested that it cannot maintain a running speed though a throttle valve distance is large and, after additional shutdown, an internal combustion engine speed reaches near the maximum speed, a matching device 41 will be operated. The matching device 41 is formed so that an engine speed is maintained constant when a target transmission gear ratio is changed instantaneously. This matching is made until an actual instantaneously adjusted transmission gear ratio or a changed target transmission gear ratio nears a next lower transmission gear ratio.
