Patent JP-H03239531-A (JP)
Title: Manufacture of solid model
Inventor: HAYANO SEIJI
IPC: B29K105/24
Filed: 1990-02-19
Abstract: PURPOSE:To avoid influences of temp. change and oxygen hindrance and to shorten remarkably manufacturing time for a model by inserting a container having an opening on its bottom in a photocurable fluid substance while inside of the container is compressed with a compressed fluid, moving the irradiated part while light irradiation is performed to form a continuously solidified part of the photocurable fluid substance. CONSTITUTION:A table 3 is sunk in a specified depth to the liq. surface of a photocurable resin 2. An irradiation device 4 is inserted in a resin liq. 2 from the upper side of the liq. surface and a compressed fluid is fed in the irradiation device 4 to push down the resin liq. 2 and the resin liq. is irradiated with a light flux. A resin liq. 2 between the irradiated part of the liq. surface and the table 3 below it is cured to form a cured product on the table. When the irradiation device 4 is moved horizontally, a cured layer 5a corresponding to the shape of the lowermost layer of a solid model is formed on the table 3. After the table 3 is lowered by a thickness of a layer of the cured layer, another cured layer 5b is formed on the cured layer.

Title: Sensor for detecting penetration of water using optical fiber
Inventor: TSUJITA TERUYUKI
IPC: G02B6/02
Filed: 1988-02-18
Abstract: PURPOSE:To accurately and quickly detect the occurrence and occurring location of a water penetrating accident by providing a water-resisting body around a tension-resisting body and winding an optical fiber around the water-absorbing body, and then, winding an expansion preventing material around the thus-formed body. CONSTITUTION:A water penetration detecting sensor 1 is constituted in such a way that a long rod-like tension resisting body 2 is covered with a water-absorbing body 3 made of a water-swelling material whose volume expands when absorbing water and an optical fiber 4 is wound around the water-absorbing body 3, and then, a thread-like expansion preventing material 5 is wound around the thus-formed body in the direction opposite to the optical fiber 4 winding direction. When water is absorbed by the water-absorbing body 3 at the time of a water penetrating accident, the body 3 swells and the optical fiber 4 wound around the swelled part is pushed outward, but the fiber 4 at the part where the fiber 4 is brought into contact with the expansion preventing material 5 is prevented from being pushed outward. As a result, bending and micro-bending are produced in the optical fiber 4 and the transmission loss of the light transmitted through the fiber 4 becomes larger at the bending and micro-bending. Therefore, occurrence and occurring location of a water penetrating accident can be detected.

Title: Photosensitive material drying device and chamber
Inventor: ISOZAKI EIICHI
IPC: G03D15/02
Filed: 1992-02-24
Abstract: PURPOSE:To efficiently discharge dry wind to a photosensitive material. CONSTITUTION:A guide 72 provided in a drying chamber is provided with an aperture 88 at one end of an approximately cylindrical guide body 86 and is bored with a slit 74 along its longitudinal direction. The slit 74 is provided along the transverse direction of the photosensitive material 14. Plural ribs 92, 94, 96 are projectingly provided within the guide body 86. These ribs 92, 94, 96 are so inclined that the dry wind supplied in an arrow B direction from the aperture 88 flows spirally along an arrow C direction. The dry wind is fed spirally into the guide body 86 and is discharged at an approximately uniform air quantity from the slit 74. Since the ribs 92, 94, 96 are formed in the state complying with the flow of the dry wind, the ribs do not act as the resistance to the dry wind.

Title: Bonding repair tool
Inventor: FUJIZU TAKAO
IPC: H01L21/60
Filed: 1979-03-30
Abstract: PURPOSE:To reduce the area of the bonding section of the bonding repair tool to be used for an electric connection from an element body to an exterior connection reed by forming the exterior shape of the tip of a repair tool to an almost vertical cylindrical shape. CONSTITUTION:The tip section 16 of a bonding repair tool (capillarity chip) has a vertical and cylindrical form. The length g of the cylinder section is desired to be the smallest possible area to meet necessity in order to prevent the decrease in the mechanical strength at the capillarity tip. As the tip section 16 has a vertical and cylindrical shape (or a tapered cylinder-shape below 10 deg.), a fine gold wire is not brought down due to the capillarity chip coming into contact with the adjoining fine gold wire, for which the bonding gas has been finished, at the time when the bonding is performed with the fine gold wire, thereby reducing the bonding area of the  element with numerous exterior connection reeds.

Title: Ultrasonic oscillator
Inventor: MORIMATSU HIDEJI
IPC: H04R17/00
Filed: 1992-02-25
Abstract: PURPOSE:To reduce the influence of a side lobe with perpendicular transmission and to enable submarine search over a wide range by reducing the strength of transmission radiated in a perpendicular direction rather than the strength of transmission in a side direction. CONSTITUTION:At an ultrasonic oscillator 1 equipped with the wide directional characteristic by being bent, a curvature at the central bent part of the ultrasonic oscillator 1 is enlarged rather than the curvature of the other part. Namely, an oscillating plane is formed not in the shape of a circular arc but in the shape of a quadratic curve (radial slit). On the other hand, plural oscillators in the shape of the circular arc or plural linear oscillators are combined and radially constituted. Thus, the strength of transmission radiated in the perpendicular direction of the central bent part on the oscillating plane can be reduced rather than the strength of the transmission in the side direction. Otherwise, a crescent-shaped sound cut-off member 5 having the maximum thickness at the lowest (central) part is provided in the lengthwise direction of the oscillator 4 (perpendicularly to the surface of paper) near the lower part of the oscillator 4 in the shape of the circular arc. In this case, the same effect can be obtained as well.
