Abstract: PURPOSE:To trap neutral atoms and charged particles other than specified isotopes to be separated so as to improve an efficiency of isotope separation and product purity by arranging groups of wires along cathodes crosswise to directions of ascending vapor streams. CONSTITUTION:Specified isotopes in a vapor stream 7 introduced into an isotope separation apparatus 15 are ionized, turned into specified isotope ions by irradiation of ionization laser lights 11 and deflected to directions at nearly right angle to those of cathodes 9 charged to respective potentials. On the other hand, as the vapor stream 7 ascends while diverging at a certain divergent angle through photo reaction parts 10 in the isotope separation apparatus 15, plural number of element wires 17 are arranged along longitudinal directions and in the vicinities of the cathodes 9 so as to prevent impurity neutral atoms in the vapor stream 7 from sticking to the cathodes due to that divergence of vapor stream. Efficiencies of separating specified isotopes to respective cathodes 9 are improved because the impurity neutral atoms., etc., are trapped by the aforementioned element wires group.

Title: Blood pressure judgement by oscillometric method and electronic hemodynamometer
Inventor: OZAWA HITOSHI
IPC: A61B5/022
Filed: 1990-03-23
Abstract: PURPOSE:To make accurate judgement on blood pressure by detecting change in magnitude between the amplitude and the threshold value of pulse wave, judging whether or not the first pulse signal after change is noise, and thereby judging each pulse wave signal corresponding to the maximum or the minimum blood pressure. CONSTITUTION:When the maximum blood pressure SYS is determined, the pulse wave signal 2 exceeding the threshold value TH1 is detected first, if the amplitude PA3 of the following pulse wave signal 3 exceeds the threshold value (PA2-C4), cuff pressure PS corresponding to the pulse wave 2 is judged as a maximum in blood pressure SYS. If the previous amplitude does not exceed the threshold value, but the amplitude PA4 of the following pulse wave signal 4 exceeds the threshold value TH1, and furthermore, if the difference in amplitude between the pulse wave signal 3 and the pulse wave signal 4 is equal to or more than a fifth specified value C5, the pulse wave signal 3 is judged that it is noise. On the other hand, when the amplitude PA3 does not exceed (PA2-C4), and when the amplitude PA4 of the following pulse wave signal 4 does not exceed the threshold value TH1 or when the difference in amplitude between the pulse wave signal 3 and the pulse wave signal 4 is less than the fifth specified value C5, the pulse wave signal 2 is judged that it is noise. By this constitution, the position of the maximum blood pressure can be accurately specified, so that reliability can remarkably enhanced.

Title: Thin film magnetic head
Inventor: KIKUIRI KATSUYA
IPC: G11B5/00
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To make reducible the resistance value of a coil without lowering the magnetic efficiency by increasing, at a constant ratio, the conductor width of a coil layer in the normal direction extending toward the outer periphery from the center of the coil layer, and setting the conductor width on a first normal extending from the center of the coil layer toward a portion facing a recording medium to be smaller than the conductor width on a second normal extending in the direction opposite to the first normal. SOLUTION: The conductor width of a coil layer 4, when a normal extending from the center 4h of the coil layer 4 in the direction toward the outer periphery of the coil layer 4 was measured, is set to increase, at a constant ratio, from the inner periphery side toward the outer periphery side. In addition, with respect to the conductor width of the coil layer 4 in each turn, the conductor width on a first normal 8 extending from the center 4h of the coil layer 4 toward a portion facing a recording medium is set to be smaller than the conductor width on a second normal 9 extending in the direction opposite to the first normal 8. Thus, an increase in a coil resistance value for each turn measured from the inner periphery side toward the outer periphery side of the coil layer 4 can be suppressed, and furthermore, the overall coil resistance value of the whole coil layer can be reduced.

Title: Recognition of wire bonder and wire bonder using method of this recognition
Inventor: KAWABATA KAZUHIRO
IPC: H01L21/60
Filed: 1990-03-22
Abstract: PURPOSE:To contrive to improve the accuracy of a recognition by a method wherein a search for a pattern is performed using the correlation between a reference image and an input image and when the search does not go well, peculiar-form information of a recognition object is compared with the reference image and the amount of the shift of a bonding position is recognized. CONSTITUTION:When an image to be searched is registered in a reference binary image memory part 8 at the time of teaching, peculiar-form information on a reference binary image is memorized. When the form of the image is the form of a pad, this information is memorized so that the dimensions, such as length and breadth and the like, of the pad can be inputted in the information and when the form is the form of a lead, this information is memorized so that the dimensions, such as a lead width and the like, of the lead can be inputted in the information. In case the search using a correlation degree does not go well, this feature form information searches an image memory part 16 and when the information coincides with the image in the part 16, a recognition is decided to be successful. A recognition failure decision in a correlation matching part 9 is decided by a CPU on the basis of information on a correlation degree in the part 9 and an activation is applied to a peculiar-form search part 17. Thereby, a high-accuracy recognition is obtained.

Abstract: PURPOSE:To obviate excessive heating of a thermal recording material or a thermal recording device itself when malfunction occurs in the thermal recording device. CONSTITUTION:In a thermal recording device 10, when malfunction of a rotating polygon 20 has been detected by a scanning sensor 36, when malfunction of a motor 26 has been detected by an encoder 38, or when bending and the like of a thermal recording material S has been detected by a pair of transfer sensors 40a, 40b, a control unit 42 sends an abnormal signal to a solenoid 30. In response to the signal, energy applied to the solenoid 30, which is always energized, is reduced and a shield board 32 interrupts laser beam L. As a result, even if malfunctions occur in the device 10, the material S and the device 10 are not excessively heated by the beam L.

Filed: 1985-04-08
Abstract: PURPOSE:To improve durability and oscillation resistance and to permit easy adjustment by providing a driving circuit which changes the refractive index of light of an optical waveguide layer and/or adjacent layer in such a manner that the guided light is emitted to the outside of a laminated body at the point applied with energy by the interaction with diffraction gratings. CONSTITUTION:When a voltage is successively impressed between the electrodes of electrode pairs A1-An and when an electric field is successively applied to inter-electrode spaces P1-Pn, the refractive index of the light of the adjacent layer 12 at the part applied with the electric field increases, and the light 14 is emitted from the optical waveguide layer 11 to the adjacent layer 12 at the parts corresponding to the spacings P1-Pn and is emitted to the outside of the layer 12 by the diffraction effect of the diffraction gratings G1-Gn. More specifically, the exit position of the light 14 changes successively, i.e., from the diffraction grating G1 to the next diffraction grating G2 first, then back from the diffraction grating G1 after the diffraction grating Gn, and therefore the body 18 to be scanned is scanned in an arrow (X) direction by the exit light 14. The body 18 is two-dimensionally scanned if the body 18 is moved in a direction Y and is subjected to auxiliary scanning by synchronizing the same with the main scanning by a clock signal CLK in perpendicular with the main scanning. The durability and oscillation resistance are thereby improved and the adjustment is made easy.
