Title: Method for rewriting utoc information of recording/ reproducing disk
Inventor: KUROHARA HIDEO
IPC: G11B27/00
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To prevent UTOC information of a recording music from being lost even if an earthquake, a power failure and the like occur before UTOC information in an UTOC area is rewritten at the time of recording. SOLUTION: A music data storage buffer 11b where music data is continuously written at first speed at the time of recording and data is intermittently read at a second speed faster than the first speed and an UTOC information storage part 11a storing UTOC information which is read from the UTOC area of a recording/reproducing disk 1 are provided. At the time of recording, sound data which is written in the sound data storage buffer 11b is intermittently read, recorded in the program area of the disk and management information of music is added to UTOC information of the UTOC information storage part 11a whenever sound data for one piece of music is recorded. UTOC information stored in the UTOC information storage part 11a is written into the UTOC area of the recording/reproducing disk in a time zone when sound data is not written into the disk.

Abstract: PURPOSE:To obtain an ultraviolet absorber that is liquid at ordinary temperature by using a 2-[2'-hydroxy-4'-(branched alkyl)oxyphenyl]benzotriazole as an effective component. CONSTITUTION:An ultraviolet absorber containing a 2-[2'-hydroxy-4'-(branched alkyl)oxyphenyl]benzotriazole of the formula (wherein R1 is 2-6C linear-chain alkyl; and R2 is 1-4C linear-chain alkyl) as an effective component.

Title: Magnetic head
Inventor: SATO TOSHIHIKO
IPC: G11B5/23
Filed: 1992-02-05
Abstract: PURPOSE:To obtain a reproduced signal in which no beat noise is caused by a method wherein the {111} plane of at least one single-crystal Mn-Zn ferrite is formed in such a way that it is directed to a direction along a gap layer and that it is non-parallel to the gap layer. CONSTITUTION:In a magnetic head 10, magnetic cores 11, 11 which are composed of a single-crystal Mn-Zn ferrite are bonded via a gap layer 12 which is composed of a nonmagnetic substance. Each core 11 is formed by cutting off the block of a cubic Mn-Zn single-crystal ferrite, the {111} plane of the ferrite is directed to a direction along the gap layer 12, the plane is not completely parallel to the gap layer 12 and the plane is tilted at about several to 20 deg. with reference to the gap layer 12. Since the {111} plane or the {100} plane of the ferrite is directed so as to be nonparallel along the gap layer 12 in this manner, a crack which is caused along the {111} plane or the {100} plane by coming into shaking contact with a magnetic tape is directed so as to be nonparallel to the gap layer 12, and a replayed signal which is picked up by a pseudogap formed by the crack does not have a large influence on a signal reproduced by a regular gap.

Title: Dry-etching method
Inventor: KADOMURA SHINGO
IPC: H01L21/302
Filed: 1991-01-22
Abstract: PURPOSE:To enable the high anisotropy, rapidity and pollution resistance to be simultaneously attained in silicon trench etching step. CONSTITUTION:The trench etching step is performed in the state wherein a silicon substrate is cooled down at the temperature below 0 deg.C using an etchant gas of S2F2 added S2Cl2. At this time, the etching reaction is anisotropically advanced mainly by ion assist reaction using ions such as Cl<->, etc., but the radical reaction is also advanced by a bit of F existing in the reaction system thereby enabling the rapid etching step to be performed. On the other hand, S produced in plasma by the discharge dissociation of said gas is deposited on the pattern sidewall part on the cooled down wafer surface thus contributing to the enhancement of the anisotropy. Furthermore, the deposited S can easily be removed by the temperature rise of the wafer or the oxygen plasma processing step so that the particles may not be polluted at all.

Abstract: PURPOSE:To dispense with many workers for assembling a rocket and to shorten assembling time, and to remove the possibility of the damage of the rocket to improve its safety by providing a floor to ascend and descend while enclosing the outer periphery of the rocket standing upright and a means for raising and lowering the floor to an optional level and keeping it there. CONSTITUTION:A work floor for a rocket is used for such works as the assembly and inspection of the rocket 1, and has an ascending and descending floor 4 whose four corners are severally supported by a wire rope 5, and is raised and lowered by winding up and extending out the wire rope 5 through an ascent and descent driving device 9, and has a fall preventing mechanism so that the floor may be stopped at an optional position and safely kept there. Thus, the rocket 1 can dispense with hanging up to a high position once in the case of its assembly to make the lowering of a tower than its usual height possible, and with passing through many floors for hanging it down. The assembly of the rocket can therefore be managed only by the ascent and descent of the ascending and descending floor 4. In addition, a footstool is unnecessary, and works can be safely and easily executed at a place having an optional level.
