Title: Laser power generator
Inventor: TAKAHASHI SATORU
IPC: G11B7/125
Filed: 1990-10-19
Abstract: PURPOSE:To eliminate power switching regulation at the time of switching a mode by deciding a current flowing to a laser diode (LD) according only to an LD current command value of each mode to be originally output from a CPU toward a current controller. CONSTITUTION:A conventional analog LD power control loop is eliminated, and an LD current is decided only according to an LD current command value by a CPU 15. In this case, after the command value of each mode is first temporarily set in a focusing servo off state, a head is moved to an innermost periphery (or outermost periphery) so as not to damage data on a disk by an optical spot, and the command value is further finally decided under a focusing servo on state. A power detection signal VPD is monitored in a steady state of a reproducing mode or an erasure mode. Thus, a circuit is simplified largely as compared with prior art, and a high speed amplifier necessary for a recording mode is also eliminated.

Inventor: MORI MITSUHIRO
IPC: H01L21/28
Filed: 1985-12-18
Abstract: PURPOSE:To reduce contact resistance and improve flatness of electrodes, by performing vacuum evaporation on an n<+> GaAs layer from an ionized Ge- vaporizing source and a P or the like-vaporizing one, to form a metallic layer on it. CONSTITUTION:An epitaxial wafer making an n<+> GaAs layer 12 and n<+> GaAs layer 13 to grow on a semi-insulating GaAs substrate 11 is covered with an insulating film 14. Then, a Ge film is put on the wafer in a vacuum atmosphere by the use of a clustered ion-ray source. As is then concurrently evaporated as a donor impurity from another crucible. P or Sb can be used as the donor impurity. Then, an unnecessary part of the n<+> Ge layer is removed to put the second-layered metallic layer 16. Finally, a gate-electrode covered part of the insulating film 14 is opened and then the n<+> GaAs layer 13 is removed by etch ing. Thus, contact specific resistance of ohmic electrodes can be reduced, with flatness of the electrodes improved without using alloy reaction.

Title: Vapor growth device
Inventor: OTO TAKASHI
IPC: H01L21/22
Filed: 1987-11-11
Abstract: PURPOSE:To prevent the generation of warpage on a susceptor by a method wherein the film thickness on the lower side of the susceptor is made 1.1-1.5 times thicker than that of the upper side of the susceptor. CONSTITUTION:The SiC film on the upper surface and the SiC film on the lower surface of a susceptor have different film thickness. The film of the upper surface is formed in the thickness of 1.1-1.5 times of the film of the lower surface. As the SiC film on the upper surface is thicker than the film on the lower surface, the downward warpage of the circumference of the susceptor can be prevented. As a result, the upper surface of the susceptor is always maintained flat, and wafers are treated in an excellent state.

IPC: G06F9/06
Filed: 1990-10-23
Abstract: PURPOSE:To attain the individual correction of the data on each unit system file by setting each program, the parameter definition, etc., in an exclusive ROM as an individual unit system file respectively and loading these files in a working memory as a single system file in response to the application of a power supply. CONSTITUTION:The unit system files which store such system data as an OS program 17a, an application program 17b, the parameter definition 17c, etc., are stored in the exclusive ROM 14 - 16 respectively. When a power supply is applied, an operating program is loaded into a working memory 17 and started by a boot ROM 13. Based on this started operating system, the unit system files stored in other exclusive ROMs are loaded so as to be connected to the directories in the memory 17 designated by the operating program. Thus it is just required to form again only the exclusive ROM that stores the corresponding unit system file when the contents of each unit system file are corrected.

IPC: G11B5/40
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To prevent the elevation of the temperature of an MR element by enhancing the thermal conductivity of a first shielding gap film and a second shielding gap film. SOLUTION: The first shielding gap film 12 and the second shielding gap film 14 are composed of insulating films which contain AlN as essential components and of which the (002) of AlN are aligned to a direction perpendicular to the film faces. As a result, the thermal conductivity higher than the thermal conductivity of the case the plural crystal planes of AlN are aligned in the direction perpendicular to the film faces is obtained and the heat generated in the MR element 13 is efficiently diffused. The insulating films may contain a small amount of Ar. In such a case, the hardness increases and the excess polishing of air bearing surfaces at the time of forming these surfaces is prevented. In addition, the insulating films may contain oxygen. Stresses are decreased and peeling is prevented by the oxygen contained therein.
