Title: Zoom lens
Inventor: KOYAMA TAKASHI
IPC: G02B15/00
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To reduce the change of a viewing angle at a focusing time and to obtain high optical performance all over an object distance while making the whole of a lens system compact by discriminating relative positional relation between a lens group and a lens group positioned in the moving direction based on data from an arithmetic means. SOLUTION: A focusing action is executed by extending the lens group L3 for executing a focusing action to a short-distance object from an infinite-distance object. At this time, the moving amount of the group L3 is obtained by the arithmetic means based on information related to a present zoom position and the present object distance. Then, when the 3rd group L3 is moved on an optical axis according to the obtained moving amount, the focusing action is executed by the movement of only the group L3 by a 2nd driving means in the case that it is discriminated that the group L3 and the 2nd group L2 do not mechanically interfere with each other.  In the case that it is discriminated that they interfere with each other, the focusing action is executed by executing a variable power action by a 1st driving means, forming a prescribed-amount of air gap between the 2nd and the 3rd groups and extending the group L3 at the zoom position obtained by the variable power action by the 2nd driving means.

Title: Selective epitaxial growth
Inventor: SHIRAISHI YASUSHI
IPC: H01L21/20
Filed: 1995-06-07
Abstract: PURPOSE: To provide a method of selective growth of an n-type GaAs at the substrate temperature which is lower than the existing temperature in the organic metal molecular beam epitaxial growth method (MOMBE method). CONSTITUTION: As the Ga raw material for growth of GaAs, both triethylgallium(TEG) and trimethylgallium(TMG) are used. Therefore, since TEG and its decomposition seed can easily be separated,from a SiO2 mask 2 because of the existence of TMG, polycrystal GaAs does not deposit on the SiO2 mask 2 and selective growth thereof can be realized under the substrate temperature lower than the existing one. Since only a little amount off carbon is mixed from TMG, low temperature selective growth of high impurity concentration n-type GaAs layer 3 can be realized through doping to n-type.

Abstract: PURPOSE:To facilitate manufacture of a motor and to improve dimensional accuracy and the characteristics by integrally forming the motor so as to provide polar anisotropic permanent magnets in the neighborhood of both ends of the motor in the axial direction and isotropic permanent magnets in the intermediate portion thereof. CONSTITUTION:Magnets 15 for a rotor, for example, using ferrite permanent magnet material are formed into a hollow and integral cylinder.
