Title: Method for measuring distance between parallel planes
Inventor: HATTORI YASUJI
IPC: G01B11/14
Filed: 1988-12-21
Abstract: PURPOSE:To speedily measure the distance between parallel planes placed opposite to each other with high accuracy by arranging an optical system and a movable Michelson interferometer at a distance. CONSTITUTION:The light emitted by a white light source 31 is converged 32, passed through a pinhole 33, and converted by a collimator lens 34 into parallel light. This parallel light is reflected by a beam splitter 35 and made incident on optical parallels 1 and 1'. Light reflected by the measurement surfaces 11 and 11' of the parallels 1 and 1' is transmitted through the splitter 35, converged 36, and made incident on an optical fiber 4. Then the light which is propagated by the fiber 4 to the movable Michelson interferometer 5 is converted by a collimator lens 51 into parallel light, which is branched by a beam splitter 52 to a fixed mirror 53 and a movable mirror 54. This movable mirror 54 reflects the light to the splitter 52 while moving at a constant speed in parallel to the direction of the light. Then the light which is reflected by the fixed mirror 53 and movable mirror 54 to return to the splitter 52 is made incident on a condenser lens 55 and then on a detector 56, which measures variation in the intensity of the light reflected by the fixed mirror 53 and movable mirror 54 due to interference.

Title: Microwave ion source for generating mass ion
Inventor: TOKIKUCHI KATSUMI
IPC: H01J37/08
Filed: 1990-11-28
Abstract: PURPOSE:To efficiently generate a mass ion consisting of mutually connected two or more equal atoms by arranging permanent magnets so as to alternately place their polarities on the periphery of a tapered structural plasma chamber, and mounting the gas introducing pipe of the plasma chamber in the vicinity of a microwave introducing side. CONSTITUTION:A plasma chamber 8 is formed into a tapered tape formed by arranging permanent magnets 9 on its peripheral part further by additionally providing a coil 2 for generating a magnetic field in the axial direction. A gas introducing port (for instance, inflow of H2 gas) is provided in the vicinity of a microwave introducing window 5. Accordingly, ions are efficiently absorbed in plasma due to an axial directional magnetic field applied by the coil 2, so that a large amount of H2<+> ion is produced in the vicinity of the microwave introducing window and the ions in the plasma are diffused to a tapered part of high plasma enclosing effect. By the time outlet these ions reach slits of drawn out electrodes 3, they make collision reaction with a neutral H2 gas molecules simultaneously flowing in diffused state. Thus the mass ion can be sufficiently generated, by efficiently performing ion molecular reaction.

Title: Metallic mold for molded power cable connecting section and method for forming molded connecting section
Inventor: MIKAMI TOSHIHIRO
IPC: H02G15/08
Filed: 1994-12-26
Abstract: PURPOSE: To prevent the occurrence of voids within a resin by providing a movable section which reduces the internal volume of a metallic mold for connecting power cables in the longitudinal direction at the central part of the metallic mold and cooling an extrusion resin fed in the inside of the metallic mold and, when the pressure in the metallic mold drops, maintaining the pressure constantly by moving the movable section. CONSTITUTION: After the conductors of power cables A and B to be connected to each other are exposed and connected to each other by compression, the connecting section of the conductors is covered with the main body 1 of a metallic mold and fixed. When the temperature in the main body 1 is raised to a specific temperature by energizing a heater 3, a polyethylene resin is extruded into the main body 1 from an extrusion resin injecting hole 6. The extrusion of the resin and the energization of the heater 3 are stopped when the pressure indicated by a pressure gauge 5 becomes constant. When the main body 1 is cooled and the pressure indicated by the gauge 5 drops to a prescribed value, a platy movable die 11 is pushed into a resin injecting hole D by rotating the screw 12 of the movable section 10 so as to raise the pressure by reducing the volume of the mold 1. When the pressure reaches a constant value, the screw 12 is stopped. Therefore, the occurrence of voids in the extrusion resin can be prevented at the connecting section.

Title: Virtual endoscope device
Inventor: YUMIZA HISAYASU
IPC: G16H10/60
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To display a virtual endoscope image having enough depth feeling. SOLUTION: The three-dimensional image data of organs are preliminarily fetched from an X-ray CT device 2 in an HDD 15 of this virtual endoscope device 1. A CPU 11 produces a surface image of an organ as if it were looked at by an endoscope, that is, a virtual endoscope image from the three- dimensional image data in the HDD 15 and expands it in an image memory 16. In such a case, the CPU 11 sets brightness when pixels constituting the image are shown so as to be darker as a distance becomes large in accordance with the distance from the viewpoint of the endoscope. After that, an image display controlling part 17 displays the virtual endoscope image data in the memory 16 on a display 18.  Thus, an image to which light and darkness are attached so that the farther from the viewpoint a pixel is, it can be the darker and which has sufficient depth feeling is shown on a virtual endoscope image shown on the display 18.

Abstract: PURPOSE:To shorten a production process and to realize a low cost by a method wherein a removed part is formed on a second face in a liquid photo-type solder- resist which is made in a standard process for a printed wiring board. CONSTITUTION:A solder-resist removed part 7 whose size is equal to or larger than that of a liquid photo-type solder-resist removed part 6 on a first face is formed on a second face so as to face the solder-resist removed part 6 on a first face. A through hole 2 and a conductor pattern 5 are formed. After that, a process to form a liquid photo-type solder resist is executed; both the first face and the second face are coated simultaneously with the liquid photo- type solder resist; then, both faces are exposed to light. At this time, ultraviolet rays are prevented from being transmitted to the first face from the second face thanks to the solder-resist removed part 7 on the second face, i.e., a part whose exposure operation is not required, which has been formed so as to face the liquid photo-type solder-resist removed part 6 on the first face; it is possible to prevent the liquid photo-type solder-resist removed part 6 on the first face from being exposed to light from the rear. Consequently, a highly accurate liquid photo-type resist is formed. Thereby, a production process is shortened, and a low cost is realized.

Title: Emergency lighting device embedded in ceiling space
Inventor: HORIUCHI TATSUHIKO
IPC: F21V19/02
Filed: 1988-12-22
Abstract: PURPOSE:To widen the light distribution without sacrificing the appearance of the ceiling surface by making a light source unit not protrude out of a case when an emergency lighting is not required, and making it protrude out of the case when the emergency lighting is required. CONSTITUTION:When an emergency power source is turned on to light a halogen lamp 4 of a light source unit 2 located in a retracted position and to simultaneously actuate a solenoid relay 11, the relay 11 attracts a member 9 to be engaged against a resilient force. This causes an engaging member 8 to come off the engaged member 9, causes the light source unit 2 located in a retracted position to rotate downward with its own weight to come to a suspended position. When an emergency power source is turned off, the light source unit 2 is retained in a retracted position in a case 1. This makes the light distribution wider without sacrificing the appearance of the ceiling surface and reduces the number of light sources to be installed.
