Title: High-pressure metallic vapor discharge lamp
Inventor: SAITOU MASATO
IPC: H01J61/54
Filed: 1983-12-08
Abstract: PURPOSE:To avoid the unstable discharge conditions at the time of starting discharge between a main electrode and an auxiliary electrode by providing a sleeve which encloses the seal base of the auxiliary electrode and has an open end inside the fluorescent tube and by bending the tip of the auxiliary electrode protruding from the open end of the sleeve. CONSTITUTION:A quartz glass sleeve 25, which is provided to enclose the seal end base of an auxiliary electrode 3, has its one end sealtightly fixed to the sealing section of the fluorescent tube and its other end opened inside the fluorescent tube. The auxiliary electrode protruding from the open end of the glass sleeve 25 is formed with its tip bent. In this way, the arcing between a main electrode 2A and the auxiliary electrode 3 at the time of starting is mainly generated at the bent portion of the tip of the auxiliary electrode 3, and therefore an unstable arcing at the starting time, especially a discharge near the seal end of the auxiliary electrode 3 can be prevented and a long life lamp can be obtained with non- lighting or degradation of light flux restrained during its service life.

Title: Device for switching optical member of camera
Inventor: MISAWA MITSUFUMI
IPC: G02B7/14
Filed: 1992-08-31
Abstract: PURPOSE:To reduce load required for switching two optical members when the optical member is taken in and out the photographing optical system. CONSTITUTION:Lens moving frames 18 and 20 respectively holding a T lens 14 and a W lens 16 are drawn to each other by a coil spring 22. By the pins 12B and 12C of a swinging lever 12, both lenses are prevented from approaching each other at a prescribed distance or more. When the lever 12 is rotated to the right, the frame 20 is pressed couterclockwise by the pin 12C and the frame 18 is rotated to a position fixed by a positioning pin 24 by being drawn by the spring 22. Then, the lens 14 is taken in a photographing position. When the lever 12 is rotated further, the tensile force of the spring 22 is restricted to a proper strength because the pin 12C is retreated to the recessed part of the frame 20. When the lever 12 is rotated to the left, the lens 16 is similarly taken in the photographing position instead of the lens 14. The lenses are switched through the spring 22 whose elongation is restricted and the load is restrained to be small.

Filed: 1987-09-18
Abstract: PURPOSE:To perform the disconnection of a desired metallic wiring without giving damage to other semiconductor device by a method wherein a poly-Si layer is locally provided under a metallic wiring layer. CONSTITUTION:In a structure, wherein a poly-Si layer 12 is locally provided under a metallic wiring layer 11 using an Al alloy wiring, a large current having a current density of 10<7>A/cm<2> or thereabouts, for example, is made to flow through the layer 11 by 1msec. Whereupon, poly-Si reacts with the layer 11 by the generation of a Joule heat and the poly-Si is diffused in the layer 11. When the poly-Si in the form of a solid solution is cooled, a crystal is deposited and an Si nodule 15 is formed in the layer 11 on the layer 12. In this state, when a current is made to further flow, an electromigration is caused and the layer 11 of a neck part 16 is fuse-cut.
