IPC: C03B37/018
Filed: 1992-11-27
Abstract: PURPOSE:To provide an apparatus capable of advancing and retreating an optical fiber preform without advancing and retreating burners. CONSTITUTION:This method for producing an optical fiber preform is to apply plural burners 3 from the radial direction of the optical fiber preform 1 according to an outside vapor deposition method. The optical fiber preform 1 is retreated in the direction opposite to the arrangement side of the burners 3 as the optical fiber preform 1 is grown and enlarged in the radical direction thereof. Thereby, the interval (L) between the tips of the burners 3 and the surface of the optical fiber preform 1 is kept at a desired proper distance.

Title: Position detection system device
Inventor: NAKAMARU TADASHI
IPC: G06F3/0488
Filed: 1991-12-25
Abstract: PURPOSE:To improve the detection precision and reduce the facility cost by calculating the position of a person image on a graphic screen as graphic coordinates and converting the coordinates into real coordinates. CONSTITUTION:An image processor 2 converts the video signal of a photographed body (person) from a camera 1 into a digital signal and projects its image on a display 3. A graphic coordinate arithmetic means 4 finds the position of the photographed body image on the graphic screen. A coordinate transforming means 5 transforms the graphic coordinates obtained by the arithmetic means 5 into real coordinates to detect the position of the photographed body on the real coordinates from equations YT-YC=HtanOY and Yr=HtanOY+ YC (1) and Xr-Xc=(Yr-Yc)/tanQx=HtanOY/tanOX and Xr=HtanOY/tanOX+XC (2). Here, the fitting height H of the camera 1 and the X coordinate Xc and y coordinate Yc are known. The functions for finding the actual positions OY and OX are only found by calibration.

Title: Water-stop material and water stop structure
Inventor: TANAKA KAZUMASA
IPC: C08L101/00
Filed: 1999-12-01
Abstract: PROBLEM TO BE SOLVED: To develop a water stop material which allows easy separation of members when the repair, on the like, is required, exerts an excellent workability at application and allows water-sealing treatment with a high reliability, and a water stop structure. SOLUTION: The water stop material has a water-activated layer (1) which becomes highly breakable in response to water on at least one side of a water- barrier base (3). The water stop structure is prepared by placing this water stop material between the members and water-sealing therewith. When water enters among the members, the water-activated layer in a dried, solid film state absorbs the water and becomes sticky, strongly attaches to the members and therefore exerts a water-stopping effect. The water-activated layer goes through repetitive drying and wetting among the members to retain a high water-stopping performance over a long time. At the time of repair, and the like, water is injected among the members, which changes the water-activated layer into a sticky, easily breakable form to allow easy separation of the members without breaking the members.  Furthermore, the water-activated layer in a solid film state does not stick to the members and therefore shows an excellent workability, allowing easy registration of the members.

Title: Reader of information medium having pre-recording pattern
Inventor: ROMEAS RENE
IPC: G11B27/19
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To reduce track pinch without causing any problem in the detection of tracking error by reversing the offset order of prerecord pattern every revolution or a part of revolution. SOLUTION: Centered ends 50 of adjacent data areas can be observed for respective scanning lines 58, 59, 60 comprising three continuous tracks while holding a specified region between them. The end 50 is defined by sectioning a prerecorded groove pattern with the specified region. Since the track element is narrower than the inter-track gap, the track appears darker than the inter- track gap when it is read out optically using a light spot 53. The track appears darker because it diffracts more light.

Title: Ultrasonic transducer and osteoporosis diagnostic system therewith
Inventor: NAKAMORI YUICHI
IPC: A61B8/00
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To exactly focus an acoustic lens onto a measuring part. SOLUTION: The ultrasonic oscillator 11 emits the ultrasonic beam pulses toward the cortex bone of a patient subject to examinations, which reach the cortex bone via the acrylic acoustic lens and the water bag, then, are returned back therefrom. The bone echo waves then generated are received. After these wave receiving signals are converted into the digital echo signals, the CPU 28 detects the echo levels, and the clock circuit 31 calculates a bone echo time of the ultrasonic beam pulses, spent between their emission and receiving the bone echo waves. The CPU 28 calculates a distance between the acrylic acoustic lens and the cortex bone surface, based on the time up to the bone echo arrival calculated therefor. The focus position adjusting system 14 is controlled, based both on the distances so calculated and the known acrylic acoustic lens' focus distances.  The water bag is then extended/contracted to focus onto the cortex bone surface. The highest echo level is then extracted from all the echo levels detected under this condition to calculate the acoustic impedance of the cortex bone.
