Title: Optical information recording and reproducing device
Inventor: SOFUE MASAAKI
IPC: G11B11/10
Filed: 1990-08-28
Abstract: PURPOSE:To reduce the quantity of light loss and to improve the reliability by detecting an RF signal and a tracking error signal by means of one optical system consisting of a birefringence crystal, an astigmatism generating means and divided photodetectors. CONSTITUTION:A laser beam from a laser diode 1 is passed through the optical system and converged on a recording medium 5, and a reflected beam by the medium 5 is converged by a condenser lens 6 via an objective lens 4 and a beam splitter 3 again, and by a knife edge prism 7, the beam is further splitted to go to the divided photodetector 8 for a focus signal and the divided photodetector 9 for an RF/tracking signal. Then, P and S wave components are separated by a Wollaston prism 10 in a system of the detector 9, and an incident beam upon the photodetector 9 is formed into convergent points in the splitting direction (an arrow A) of the P and S wave components of the beam on the photodetector surface by a cylindrical lens 11, while astigmatism is presented without forming any convergent point in the direction of the tracking error signal (an arrow B). By this method, the tracking error is taken out from the reflected beam without deteriorating characteristics of the RF signal, and the reliability is improved.

Abstract: PURPOSE:To improve the reliability of a semiconductor device by preventing the intrusion of a crystal defect in the end section of an island forming region formed to a semiconductor substrate when polysilicon in the island forming region is changed into a single crystal through annealing using energy beams such as laser. CONSTITUTION:Insulating layers 12 consisting of SiO2 are formed on a silicon substrate 11 through a thermal oxidation method. When silicon is grown on the whole surface through an epitaxial method, a single crystal layer 13a is grown on an exposed window 16 section in the substrate, but polysilicon 13b is applied on the insulating layers 12 composed of SiO2. Sections 17 as terminals on the scanning of laser beams in polysilicon 13b on the insulating layers 12 are removed through etching by a photolithography technique. Polysilicon 13b is changed into single crystals through laser annealing. Epitaxial layers 13 are turned into single crystal silicon layers 15 through laser annealing. When single crystal silicon around the insulating layers 12 is changed into SiO2 through a selective oxidation method lastly, single crystal islands, bottoms and peripheries thereof are isolated by SiO2, are formed on the insulating layers 12, and desired elements are shaped to islands.

Title: Manufacture of magneto-optical recording medium
Inventor: FUNADA SHIN
IPC: G11B11/10
Filed: 1987-09-09
Abstract: PURPOSE:To improve the accumulating speed of spatering by spatering the plural numbers of targets which are mutually inclined to the both of a substrate surface and the other target. CONSTITUTION:The plural numbers of targets 101 and 102, which are mutually inclined to both of a substrate surface 105 and the other target, are spatered. By inclining the targets to the substrate surface 105, the spater grain of a specified outgoing angle can be selectively stuck on the substrate. Thus, component distribution, which is generated when an alloy thin film is made from an alloy target, can be suppressed and a spatering rate can be improved by utilizing that the number of the grain to be spatered in an inclining direction to the normal of a target surface is large. Thus, the speed to accumulate a material by the spatering can be increased.

IPC: G01R13/20
Filed: 1990-08-28
Abstract: PURPOSE:To enable highly accurate measurement by providing a function which allows automatic detection of the generation of aliasing to prevent mistaken reading of a time base. CONSTITUTION:A counter 10 counts a sample clock applied to an A/D converter 3 during one cycle of an input signal and a discriminator 11 outputs an aliasing alarm signal when counts (i) of the counter is i<2. A display controller 7 shows the generation of an aliasing at a part of a display screen of display 8 to warn an observer. An alarm signal to be outputted from an output terminal 12 informs the observer of the generation of the aliasing in a form different from that on the display screen, for example, an alarm lamp and a buzzer. In other words, this enables automatic detection of the presence of possible aliasing to prevent mistaken reading of a time base thereby assuring a highly accurate measurement.
