Title: Finder structure for camera
Inventor: KUDO TORU
IPC: G03B13/06
Filed: 1993-08-27
Abstract: PURPOSE:To provide a finder structure for a camera which is provided with a shutter opening display means so that a photographer can recognize the opening/closing state of a shutter in the case of photographing by a twin lens reflex camera. CONSTITUTION:The optical system of the finder 10 is constituted of an objective lens 12, a roof prism 14, a reticle plate 16, a 1st reflector 18, a 2nd reflector 20, and an ocular 22. The 1st reflector 18 is made to freely rock by setting the vicinity of its one side as a shaft 18a. At ordinary time when the shutter is closed, the 1st reflector 18 is set at an angle at which an optical axis S1 is bent to the 2nd reflector 20. When the shutter is opened, the 1st reflector 18 is set at an angle nearly perpendicular to the optical axis S1 from an object. Since the finder 10 blacks out when the shutter is opened, the photographer can recognize that the shutter is opened.

Title: Method and device for laser abrasion for energy to be coupled with film stack
Inventor: GALLO ANTONIO R
IPC: B23K26/06
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To improve the yield of a fuse blow by improving the quantity of laser energy coupled with a dielectric film stack and, at the same time, to reduce the instability of a fuse blow process caused by the alteration of the dielectric film stack, by making a laser beam nonvertically incident on the film stack. SOLUTION: Laser abrasion is performed on the fuse of a multilayered dielectric stack on a wafer having an integrated circuit device. At the time of performing the laser abrasion, the incident angle θof a laser beam 21 from a laser device is set in accordance with the refractive index of the dielectric substance of the stack. Then, the laser beam 21 is made incident to the dielectric stack at the angle θ so as to reduce the instability of a whole process caused by the alteration of the stack, by improving the coupling of the laser energy with the stack. The angle θ is set by relatively inclining a wafer against the laser device or by deflecting the laser beam 21 against the wafer.

Title: Active matrix substrate and its production
Inventor: MATSUSHIMA YASUHIRO
IPC: H01L29/78
Filed: 1992-09-03
Abstract: PURPOSE:To improve ON/OFF characteristics of a TFT by providing a metallic film which covers a channel part and an intermediate-density impurity area. CONSTITUTION:The TFT in LDD(Lightly Doped Drain) structure has the metallic film 15 formed covering at least the channel part 12 and intermediate-density impurity area 23 of a semiconductor layer 30. Consequently, light never irradiates the channel part 12 by traveling around and the OFF current of the TFT at the time of light irradiation is prevented from increasing. Further, a voltage can be impressed to the metallic film 15, which further operates as a subgate for the TFT. Consequently, the OFF current of the TFT is decreased and the ON current is increased.

Abstract: PROBLEM TO BE SOLVED: To record and/or reproduce an optical disk even when the optical disk has a different thickness of a substrate by providing a variable aperture means for changing the transmissivity of light in accordance with the thickness of the substrate of the optical disk. SOLUTION: When an optical disk of a comparatively thin disk substrate is reproduced, a variable aperture means 15 is set with a dimmer part 15b opaque. In this state, after a light beam from a semiconductor laser element 11 is reflected by a beam splitter 12, the beam is passed through the aperture 15c of the means 15 and converged on the surface 16 of the optical disk through an objective lens 13. At this time, the numerical aperture Na is set to be NA=O.6, spherical aberration is suppressed to be low and the light beam is exactly converged on the disk surface. When the substrate is comparatively thick, the dimmer part 15b is set to be transparent, the numerical aperture is set to be NA=NAO, a lens 13 is designed whose spherical aberration is most suppressed for the optical disk of the thickness of the substrate and the light beam is exatly converged on the disk surface.
