Title: Floating type optical pickup device
Inventor: TANAKA TOSHIYUKI
IPC: G11B7/12
Filed: 2002-11-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide a floating type optical pickup device, in which the generation of a coma aberration can be prevented even though it is used in a long period of time under the environment with large temperature change.  <P>SOLUTION: A slider and an objective lens in the floating type optical pickup device are integrally formed by same materials. By this arrangement, coefficients of thermal expansion of the slider and the objective lens are coincident, and dimensional changes of them with respect to the temperature change of them are equal, then the change of contraction/expansion different in the slider and the objective lens does not occur even though the device is used in a long period of time under the environment with large temperature change. Consequently, an optical axis of the objective lens does not change with respect to the slider even though the device is used in a long period of time under the environment of large temperature range, then the reliability of the slider is improved since the light from a light source can be converged on a recording surface of the recording medium with the specified condition.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a III-V group compound semiconductor crystal by which a composition is controlled for high qualification together with C doping when a C doped GaAsSb compound semiconductor is grown by metal organic vapor-phase epitaxy.  <P>SOLUTION: The method is used to manufacture a III-V group compound semiconductor crystal by doping a carbon C to a III-V group compound semiconductor wherein a V group element contains at least arsenic As and antimony Sb by using halocarbon.

Namely, the supply quantity of AsH<SB>3</SB>is reduced only for a period t1-t2 for supplying the halocarbon. Thus, the halocarbon promotes the decomposition of AsH<SB>3</SB>, and an increase in effective As supply quantity in a vapor phase is subtracted in advance from the supply quantity of AsH<SB>3</SB>, thereby preventing a composition change due to the halocarbon to make a crystal higher in quality.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
