Abstract: PURPOSE:To eliminate a dimensional difference between a formed active region and an initially designed active region and also a level difference between an active region and a non-active region by a method wherein an oxide film serving as a field is formed first, and then the active region is formed through etching. CONSTITUTION:A thermal oxide film 2, a polycrystalline Si film 3, a nitride film 4, and an oxide film 5 are successively formed on an Si semiconductor substrate 1, then the oxide film 5 and the nitride film 4 are removed by etching to form a pattern 7. Then, the same ions with the semiconductor substrate 1 are implanted to form a channel stopper layers 8 and 9 higher than the substrate 1 in impurity concentration, and an oxide film 5a is removed from whole the surface by etching after a resist 6 is removed. The surface layer of the polycrystalline Si film 3 is thermally oxidized, the nitride film 4a on an active region and the polycrystalline Si film 3 just under the nitride film 4a are removed, and polycrystalline Si oxide films 3a and 3b and an oxide film on the active region are all removed through etching. Then, the polycrystalline Si film 3 on the field is removed, and an active region 30 is filled with Si as high as field oxide films 2b and 2c. By this setup, a dimensional difference between a formed active region and an initially designed active region can be eliminated, and a level difference between an active region and a non-active region can be also eliminated.

Title: Focus controller
Inventor: ISHIKA TAKESHI
IPC: G02B7/28
Filed: 1987-09-30
Abstract: PURPOSE:To make an optical system, in which a high-sensitive detecting signal is obtained compact by detecting light beam components passing through a refracting body and the light beam components not passing through the refracting body, and generating a control signal. CONSTITUTION:A reflecting light beam from an information recording medium 1 is focused by a focusing means, and the approximate half of the focused light beam are shielded by a shielding means 18. The approximate half of the components of the light beam not to be shielded by the shielding means 18 pass through the refracting body and are directed to a light detecting means 19. At the time of passing through the refracting body, to the light beam components, a divergence character is slightly given. Consequently, the light beam components passing through the refracting body and the light beam components not passing through the refracting body are directed to focusing points mutually different, and beam spot segments different in size are formed on the light detecting means 19. The form change is detected by the detecting means, and converted to the control signal by a control means. Thus, the compact optical system detecting a focus and a track with a high sensitivity can be obtained.

Abstract: PURPOSE: To semi-permanently secure energy by letting electricity be generated while being connected to a generator, or letting the device be directly used as a power while being combined with the various kinds of means and machines. CONSTITUTION: Let the resiliency of a repulsive magnet 15 against a circular magnet 12 provided for the lower surface of a double valve gear 11, for example 10Kg, act on a right and a left driven spur gear 4 and 5 in a different ratio, for example three to seven. In this case, the torque of 3Kg thereby acts on the left driven spur gear 4, the torque of 7Kg acts on the right driven spur gear, and simultaneously let the right handed torque of, for example 5Kg act on a right pulley 8 by a spring 10. The aforesaid right handed torque is then transmitted to the left driven spur gear 4 via a belt 9 and a pulley 6, since the right handed torque of 5Kg thereby acts on the driven spur gear 4, finally the driven spur gear 4 is subjected to the right handed torque of 2Kg.  On the other hand, since the left handed torque of 5Kg acts on a driven spur gear 5 by the reaction force of the spring 10 via a pivot section 11, finally the driven spur gear 5 is thereby subjected to the right handed torque of 2Kg.

Abstract: PURPOSE:To make it possible to apply processing even to a narrow space between electrodes with a high degree of precision by cutting off irregularities, in width direction, of resistor due to the limit of printing accuracy by applying laser beam etc., after the printing of resistance paste and before burning. CONSTITUTION:Separate electrodes 3 and a common electrode 4 are disposed on an insulated substrate 1 and heat storing layer 2, and resistance paste is applied thereto in a main scanning direction by screen printing. Thereafter, in order to remove diluents having been added to allow smooth coating in printing, said paste is dried at about 150 deg.C. And before burning, laser beam is applied to part of resistor 5 along the main scanning direction of recording to cut off excessive resistor 6 protruding on both sides in the width direction. In this manner, a resistor 5 provided with precise picture element and resistance value can be formed. Energy of the laser beam applied in this case is about 1/5 or less of energy required for cutting after burning, hence damage to the electrodes 3 and 4 is negligible and influence on resistance values of resistor due to laser processing can be neglected.
