Patent JP-H11214313-A (JP)
Title: Method for mixing gases and gas piping used therefor
Inventor: INOGUCHI YASUHIRO
IPC: H01L21/22
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To stably mix gases of different flow rates to realize a uniform concentration, by causing two or more types of gases to merge in the state where the gases flow in the same direction and thus mixing the gases. SOLUTION: A dilution carrier gas CG from a gas cylinder 11 is fed to a mixture tube 1 through a mass flow controller(MFC1) 12 and a gas tube 13. On the other hand, a doping gas DG emitted from a gas cylinder 14 is fed to a nozzle 2 in the mixing tube 1 through a mass flow controller(MFC2) 15 and a gas tube 16. In this case, the carrier gas CG and the doping gas DG are caused to flow in the same direction and then mixed in the mixing tube 1. The mixed gas MG is fed to a gas tube 17 and then fed to a vapor phase growth(VPE) reaction tube A through a mass flow controller(MFC3) 18 and a gas tube 19. Then, a single crystal is grown on a substrate B. By thus causing the carrier gas CG and the doping gas DG to flow in the same direction and then mixing the gases, the gases can be mixed uniformly even when the gases have different flow rates.

Title: Permeation type phase difference electron microscope
Inventor: TSUNO KATSUSHIGE
IPC: H01J37/147
Filed: 1989-01-25
Abstract: PURPOSE:To make it possible to obtain a phase difference image using a permeation type electron microscope by providing a means to obtain an enlarged image by permeation electrons, and a means to obtain a difference in permeation images using part of diffraction images different from each other. CONSTITUTION:A throttle 14 is disposed at a position in a back focus surface to break a diffraction image formed in about half of its range about an optical axis 18. A diffraction image 19 is broken, and an electron microscope image by a diffraction image 20 only can thus be obtained. After the electron microoscope image based on the diffraction image for one side of the optical axis 18 is thus obtained, the opposite side, or the side of the diffraction image 20, is broken by the throttle 14, so an electron microscope image by the diffraction image 19 only is obtained. Only an image based on phase information shifted to the left side (or right side) of the optical axis can thus be obtained at a certain time. Only an image based on phase information shifted to the right side (or left side) of the optical axis can be obtained next. By taking the difference between these two images, a phase difference image can be obtained.

Title: Display panel and image display device
Inventor: KANAI IZUMI
IPC: H01J9/227
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a display panel and a display device capable of attenuating harmonic components and decreasing granular feeling by gently varying the distribution of luminous spots.

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To obtain a structure capable of inducing a large deformation of a vibrator plate even with application of a comparatively low voltage by eliminating formation of a fine gap between the vibrator plate and an electrode. SOLUTION: A recording head comprises a discharge opening 9 for discharging a recording body, a pressurizing liquid chamber 7 for adding discharging pressure to the recording body, a vibrator plate 6 which forms a part of the pressurizing liquid chamber 7, and an electrode 3 arranged at a position opposite to the vibrator plate 6, wherein the vibrator plate 6 is deformed by an electrostatic force working between the electrode 3 and the vibrator plate 6 and the recording body is discharged from the discharge opening 9. When a voltage is applied between the vibrator plate 6 and the electrode 3, an electrostatic attraction works between them and the vibrator plate 6 is attracted in the direction of electrode. When the voltage is high, the vibrator plate 6 deforms until it comes in contact with a protective layer 4.  The deformation of the vibrator plate 6 occurs in sequence from a thinnest part 63 of the vibrator plate to a thick part 61, so that a large displacement occurs by a comparatively low voltage even at the final thick part 61.
