Patent JP-S60157738-A (JP)
Title: Optical information detector
Inventor: MORIMOTO YASUAKI
IPC: G02B7/28
Filed: 1984-01-26
Abstract: PURPOSE:To eliminate almost completely the noise induced by the return light as well as the influence of a diffraction effect due to a pit, by setting concave and convex lenses having circular openings centering on the optical axis so that the relfected light passes through both lenses and also using a photoelectric transducer divided concentrically int plural parts to a photodetecting means. CONSTITUTION:Reflected light given from a disk 5 is made incident on a photodetector 8 after passing through a concave lens 6 and a convex lens 7 having circular openings. In this case, the focal position of the lens 6 is coincident with of the lens 7. The light beams received the effects of both lenses and the light beams received no effect of lenses are discontinuous at dark areas shown by oblique lines. A photodetector 8 is divided into 8a-8d, and a focusing error can be detected by obtaining a differential output between detectors 8b and 8c. Both 8b and 8c receive no light in a focusing mode. This can avoid the effects due to an uneven distribution of intensity caused by a diffraction effect of a pit or the control band noise due to the return light.

Title: Semiconductor memory device
Inventor: KODAIRA TOSHIMOTO
IPC: H01L27/102
Filed: 1978-02-07
Abstract: PURPOSE: To prevent occurrence of the crack of the passivation film and thus to avoid dispersion of the fuse material in case the blown fuse takes place by using the lamination film of the organic film or the inorganic film of the organic film and the SiO 2  film and others for the passivation film of the fuse material.  
     CONSTITUTION: Fuse 16 is formed in a fixed shape onto Si substrate 12 to be the collector region to which base region 13 and emitter region 14 are formed via SiO 2  film 15. The opening is drilled to film 15 on region 14, and fuse 16 is connected to region 14 on film 15 by coating circuit wiring 17. Thus, a fuse-type semiconductor memory device is obtained, and the double-layer film of the organic film or the organic film and the inorganic film is used for passivation film 18 to protect the surface of the memory device. As a result, the impact caused by fuse 16 blown with the overcurrent flowing to the memory device can be absorbed into the double- layer film, thus avoiding the damage of the film as well as intrusion of the ion from outside.
