Title: Method of manufacturing electron beam deflecting electrode
Inventor: YAMAGUCHI HIROSHI
IPC: H01J29/74
Filed: 1979-02-13
Abstract: PURPOSE: To form a conductive film pattern of an electrostatic deflecting yoke on the inner wall of a glass cylinder precisely and quickly by a laser processing method.  
     CONSTITUTION: A laser beam 17 produced from a laser oscillator 8 is reflected by a mirror 9 and then reduced in diameter through an iris 33 before being condensed through a cylindrical lens 30 on a conductive film of an electrostatic deflecting yoke 1. Through the cylindrical lens 30 the laser beam 17 is condensed to a linear form having a narrow width. The cylindrical lens 30 has a rectangular sectional profile in the circumferential direction of the electrostatic delfecting yoke 1, so that the laser beam 17 is not condensed in this direction. An electrostatic deflecting electrode is thus formed by reciprocally moving the electrostatic deflecting yoke 1 with a holder 11.

Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To correct influence of radon existing in the natural world and exactly judge the presence of radiation contamination even if the influence of natural radiation is not estimated otherwise by correcting the measuring value of a βray by the value of the β ray which a natural radioactive nuclide emits, and using it for contamination judgement. SOLUTION: An α ray and a β ray which a natural radioactive nuclide emits can be separated and measured with discrimination circuits 5a, 5b and the emission ratio of the measured α ray and β ray due to the natural radioactive nuclide can be calculated previously. Next, a radiation emitted from a specimen is detected with a radiation detector 20, and the a ray and the βray are separated and measured from the detected signal. The value of the β ray due to the natural radioactive nuclide contained in the measured value of the β ray is found, the value of the βray due to the natural radioactive nuclide is corrected to be deducted from the measured value of the β ray.  Accordingly, contamination judgement can be performed with the β ray measured value of high reliability in which the influence of the β ray due to the natural radioactive nuclide is eliminated.

Title: Method for removing coating film
Inventor: ITOU TETSUO
IPC: C09D9/00
Filed: 1982-02-01
Abstract: PURPOSE:To easily remove a useless coating film having a strong adhesive force, by covering the surface of a coating film to be removed with a fiber sheet, impregnating the sheet with a vinyl monomer, and covering the surface of the sheet with an impermeable sheet. CONSTITUTION:The surface of a coating film to be removed is covered with a fiber sheet of a woven or nonwoven fabric or a felt-like fiber sheet impregnated with an org. solvent or a vinyl monomer such as styrene monomer or vinyltoluene monomer as a peeling agent. Alternatively, after the film is covered with said sheet, the sheet is impregnated with said org. solvent or said vinyl monomer. Immediately after impregnation, said sheet is covered with an impermeable sheet such as a vinyl chloride or vinyldene chloride sheet to prevent said org. solvent from being evaporated. In this way, the org. solvent or the monomer is contacted with the coating film, and penetrates into the film, whereby the adhesion of the film is deteriorated. Thus, the film can be easily removed.

Title: Piezoelectric single crystal wafer and its manufacture
Inventor: ITO KUNIHIRO
IPC: H03H3/08
Filed: 1990-01-25
Abstract: PURPOSE:To prevent occurrence of crack, chipping and flaw on a wafer and to improve the yield of products by lapping a piezoelectric single crystal wafer through the use of abrasive grain obtained from abrasive grain with specific grain size added with finner grain and roughing the wafer. CONSTITUTION:Abrasive grain whose grain size is #100-#400 is added with abrasive grain with finner grain size. As a result, abrasive grain whose grain size is small enters gaps of abrasive grain with larger grain size and the load exerted to the abrasive grain with larger grain size is scattered and reduced. Silicon carbide, alumina or diamond powder is used for the abrasive grains. As the abrasive grain with fine grain size, the abrasive grain with grain size of #500-#1000 specified with the JIS R-6001 is used corresponding to the grain size of the abrasive grain with larger grain size is used. The added quantity is in a range of 5-35% in weight with respect to the abrasive grain with larger grain size. The dispersion in the surface roughness Ra in the wafer plane of the wafer obtained in this way is within + or -15% with respect to the mean value.

Title: Measuring method of particle size of magnetic powder
Inventor: KAMIYA SHINJI
IPC: G01N33/543
Filed: 1990-01-25
Abstract: PURPOSE:To realize highly sensitive and highly accurate measurement without influences of a coexistent substance by a method wherein a magnetic field is impressed to a suspension of magnetic fine particles to orient the particles in one direction, and the residual magnetic flux density of the magnetic fine particles is measured after the impression of the magnetic field is stopped. CONSTITUTION:A magnetic field is impressed to a suspension in one direction (in a direction of a magnetic flux generated from a coil of a magnetic flux meter). At this time, since the magnetic fine particles are dispersed in the suspension, the spin of particles is oriented in one direction. After the orienting process for a predetermined time (generally 1-10 minutes), the impression of the magnetic field is stopped. As a result, the residual magnetic flux density of the suspension is attenuated rapidly at first, and gradually afterwards. For evaluating the residual density, the residual magnetic flux density after a predetermined time (within about 10 minutes) has passed since the impression of the magnetic field is stopped is measured, or the residual magnetic flux density in the predetermined time is measured and an integrated value of the measured density to the time is obtained. Accordingly, it becomes possible to measure the particle size of the magnetic fine particle included in an unknown sample by obtaining the correlation of the residual magnetic flux density of the magnetic particle to that of various kinds of known samples from a calibration curve.
