Title: Device for producing intermetallic compound powder and production of same powder
Inventor: MURAHASHI NORIAKI
IPC: B22F9/04
Filed: 1991-09-03
Abstract: PURPOSE:To produce powder where intermetallic compounds are completely formed. CONSTITUTION:A thermocouple 7 is fitted to inside an arm 3 turning in an attriter body 1. When a rotating shaft 2 is tuned, rotary balls 5 strike against a raw material 25, causing intermetallic compounds to be formed. At this time, heat is generated to raise the surface temp. of the powder. When the formation of the intermetallic compounds is fully completed, heat is not generated, permitting the surface temp. of the powder to be rapidly changed. Thereby when the temp. in the neighborhood of the powder is measured by the thermometer 7 to detect a point of time when the temp. is discontinuously changed, it is recognized that the formation of the intermetallic compounds is completed. Powder where intermetallic compounds are completely formed is produced irrespective of conditions, such as the diameter and number of the rotary balls 5 and the revolution of the rotating shaft 2.

Title: Photomagnetic recording system
Inventor: EDOKORO SOTARO
IPC: G11B11/105
Filed: 1984-10-24
Abstract: PURPOSE:To obtain a recording medium consisting of a multi-layer film containing a ferromagnetic matter and an anti-ferromagnetic matter together with a new photomagnetic recording system, by securing such a structure where at least one or more of ferromagnetic layers and anti-ferromagnetic layers are laminated alternately. CONSTITUTION:An external magnetic field HW of a fixed level is applied to a recording medium in the direction opposite to the magnetizing direction of the ferromagnetic matter of the recording medium. n this case, the size of the field HW is set smaller than the coercive force HCR of the recording medium obtained at a room temperature and also larger than the coercive force HCF shown by a ferromagnetic matter at a temperature higher than the nail point. Then the laser light is modulated in response to the record data, and the recording medium is heated partly by the laser light (power PW) to increase the temperature of the recording medium up to a level higher than the nail point. This eliminates the magnetic connection between the ferromagnetic and anti-ferromagnetic matters of the recording medium. Then the coercive force is reduced down to HCF from HCR. The area heated by the laser is affected by the external magnetic field. Thus the magnetizing directions of the ferromagnetic matters of the heated area are unified toward the external magnetic field. The magnetization of the ferromagnetic matter is fixed in a cooling process, and the magnetizing direction is inverted only at the part irradiated by the laser light. Thus the recording is attained.

Title: Surface analyzer
Inventor: YAMADA HIROSHI
IPC: G01B11/30
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To detect inclination of an uneven part in a surface of a measured object, in a surface analyzer for analyzing a surface condition of the object. SOLUTION: A laser beam L1 output from a light emitter 2 is reflected with an angle θb different from an incident angle θa, when a surface 1a of a measured object 1 has an uneven part. A reflected light L2 therein gets incident in a position different from a coordinate origin set at first when it gets incident onto a light receiving face 3a of a light receiver 3. For example, a light receiving element 32 different from a light receiving element 31 existing in the coordinate origin detects the reflected light L2. Since a distance between a reflection point P1 on the surface 1a of the reflected light L2 and the receiving face 3a is known preliminerily, the reflection angle θb of the light L2 is found based on a coordinate position of the detecting light receiving element 32.  Since the reflection angle θb is expressed by an expression θb=θa+2θc when the θc represents inclination of the uneven part of the reflection point P1 on the surface 1a, the θc is found by substituting the θa and θb in the expression to detect an inclination angle of the uneven part.
