IPC: A61B6/00
Filed: 1989-03-24
Abstract: PURPOSE:To facility the confirmation of the position of a catheter by taking up an electrocardiographic wave form when the catheter is advanced while observing a X-ray fluoroscopic image, and by freezing an fluoroscopic image having the same electrocardiographic phase as that of a reference image, and by displaying the fluoroscopic image together with the reference image. CONSTITUTION:An X-ray is irradiated from an X-ray generating device 2, and an image forming agent is injected into a vein from an injector 9. Thus obtained image is converted into a photosignal by an image intersifier 3, and is then digitalized by an A/D converter. This image is stored in one of memory sections 6a, 6b,... in a memory device 6 which correspond respectively to individual images, while an electrocardiographic wave form from an electrocardiograph 13 is stored in a memory section 14, and is then analog-converted by a D/A converter 11 so as to be displayed on one side of a display device 7. When a balloon catheter is inserted, a fluoroscopic image is displayed on the other side of the display device 7. In an image processing device 5, a latch 16 latches the electrocardiographic wave form the electrocardiograph 13, and one of the taken-up images is designated as a reference image. When an electrocardiographic wave having a phase equal to that of the reference image is delivered from the electrocardiograph 13, an image freezing signal is delivered so as to display the image together with the reference image.

Title: Mutli-stage stacked glasses incorporated with optical fiber
Inventor: KATSUKAWA HIROYUKI
IPC: G02B6/00
Filed: 1989-03-23
Abstract: PURPOSE:To prevent a glass main body from breaking owing to the thermal expansion of a sealing material, to prevent a ground-fault accident from occurring owing to a leak current, and to maintain joining strength for a long period by sealing end surfaces of both glass main bodies to be joined with an adhesive material and forming a gap between the adhesive material and sealing material. CONSTITUTION:The end surfaces of both the glasses 1 are sealed with resin 5 as the adhesive material. Further, the gap S formed between the resin 5 and silicone rubber 4 absorbs the expanding silicone rubber 4 when the silicone rubber 4 expands thermally. Consequently, rain water is prevented from passing between the end surfaces and reaching a through hole 2 from outside, so a leak current is prevented from flowing to cause a ground fault. Further, the joining strength between both the glass main bodies 1 is maintained for a long period.

Abstract: PURPOSE:To obtain a film having low resistivity required as the characteristics of an electrode in a semiconductor device at the high speed of film-formation by bringing discharge-current density at a time when a metal-nitride electrode film is formed through DC glow discharge within a range of a specific value. CONSTITUTION:A mixed gas of the vapor of TiCl4 and N2 and H2 is used as a raw material gas in order to form a TiN film. The inside of a reaction vessel 1 is evacuated by an evacuating system 3 first, the raw material gas is introduced into the reaction vessel 1, and DC voltage is applied between a cathode 5 and an anode 6 to generate glow discharge. The raw material gas is decomposed and activated by glow discharge to generate a reaction, and the TiN film is formed on the surface of an Si substrate 4. The resistivity and speed of film-formation of the formed TiN film largely depend upon discharge-current density. Accordingly, low resistivity required for an electrode is obtained within a range of 0.05-0.5mA/cm<2> discharge-current density. The speed of film-formation is also fast within the range, and film thickness required can be acquired in a short time.

Abstract: PROBLEM TO BE SOLVED: To manufacture a holography optical element by constituting it out of transparent material formed with a pin hole forming a beam splitter on the nearly center part of unicolor diffused light, and a computer hologram having a specific phase pattern. SOLUTION: By applying one sheet of holography optical element(HOE) to the three elements, a beam splitter, a lens, and a pin hole, miniaturization is realized. Namely, on the surface of transparent resin 5, the HOE 22 forming the center part (pin hole part) so as to have action as the lens 6 and the beam splitter 7, and forming computer hologram(CGH) of n-value (n>2) in the territory 8 of the circumference is used. Because the HOE 22 can be constituted to be thin even in the case of using a wide angle light source, miniaturization is attained. Since the circumferential territory 8 of the pin hole is constituted out of CGH of multi-value, it can be designed so as to have light shading performance, thus reducing cost.
