IPC: A61F13/56
Filed: 1990-10-16
Abstract: PURPOSE:To effectively transfer the body fluid to an absorptive core by making the surface sheet from the thermoplastic synthetic resin fiber, forming a liq. pipe from a part of the sheet and making the liq. pipe denser than the tube wall at its lower surface open end. CONSTITUTION:A molten polymer is discharged from a melt blower, extremely finely fiberized by the air current at a high speed and temp. and deposited on the upper surface of a conveyor having the same shape, size and arrangement as an opening 13a to form a nonwoven fabric. A negative pressure is simultaneously exerted on the desired region of the nonwoven fabric while the fiber is still soft by a suction arranged on the lower surface of the conveyor to suck and draw down the nonwoven fabric part positioned at the openings of the conveyor, hence the sucked part is sagged as the tubular part having an opening on its upper surface, and a waveguide 13 having openings 13a and 13b respectively on the upper and lower surfaces is formed. The end edge of the lower-surface opening 13b is then brought into contact with a heating roller positioned on the lower surface side of the conveyor and rotating in the same direction as the conveyor and melted to form a rib 14. Consequently, the opening of a liq. pipe is hardly deformed or collapsed, and the body fluid is effectively transferred to an absorptive core.

Filed: 1993-11-08
Abstract: PURPOSE:To allow the measurement of vehicle position with respect to a white line on a pavement by approximating the midpoint of right and left outline point to a curve of secondary degree thereby measuring the vehicle position. CONSTITUTION:A video camera 1 picks up the image of pavement in front of a vehicle and then the edge component is extracted using an edge extraction filter. In order to extract an edge component representative of the outline of a white line, a threshold value setting means 3 retrieves an image exceeding a threshold value from the center of an edge image for setting the threshold value using an edge intensity toward the right and left sides and extracts a first pixel exceeding the threshold value as an outline of white line. A midpoint is calculated for each scanning line on which the right and left outline points exist. Means 6 for approximating to a curve of secondary degree determines the center line of an approximated lane by applying the method of least square to the midpoints. A vehicle position measuring means 7 determines the intersection of the center line and a line having inclination y=Ftantheta (F: focal distance of lens, theta: inclination angle of y-axis with respect to Y-axis) using an image coordinate system (x, y) and a world coordinate system (X, Y, Z) fixed to the vehicle thus determining the X coordinate of the intersection.

Inventor: KATO TAKASHI
IPC: H01L21/3205
Filed: 1989-10-25
Abstract: PURPOSE:To prevent the defective contact between a substrate and a wiring or between multilayer interconnections due to spontaneous oxidation and to prevent the occurrence of hillocks in an aluminum wiring by using gas plasma wherein rare gas is a main substance and hydrogen carbide is an additive, and treating the surface of a semiconductor substrate or the surface of a wiring layer formed on the substrate. CONSTITUTION:The inside of a vacuum cell 11 is evacuated with an exhausting device. For example, Ar gas into which 1% CH4 is added is introduced. A high-frequency voltage is applied to an electrode 12, and plasma is generated between the electrode and the vacuum cell 11. Thus, the surface of a silicon substrate 6 is etched. A high-frequency sputtering device is used, and an SiO2 film on the silicon substrate is etched with the Ar gas into which CH4 is added. At this time, when the adding ratio of CH4 is 0.1% or less, the etching speed becomes approximately constant and approaches the speed with pure Ar. The etching speed is conspicuously increased from the CH4-adding rate of 0.2%. The speed becomes the maximum value in the vicinity of 0.7%. Then, the speed decreases rapidly. The etching speed becomes zero in the vicinity of 2%.

IPC: F25D19/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce the number of component parts of an evaporator and eliminate a bending work for the radiation fins. SOLUTION: A fuse holding element 37 is assembled to an evaporator 32. This fuse holding element 37 holds a temperature fuse 45. This comprises a pair of hooks 42 fitted to a different straight pipe 35 of the evaporator 32 and a hook 42 fitted to a U-shaped pipe 35. Due to this fact, since the displacement motion of the straight pipe 35 is restricted by the fuse holding element 37, the evaporator 32 does not require the end plate, and further the number of composing parts is reduced. Further, since the fuse holding element 37 is position set against the evaporator 32, it does not become necessary to restrict the position set state by the thermal radiation fins 34. Due to this fact, since a degree of freedom in arrangement of the thermal radiation fins 34 is improved, certain troublesome operation for bending the radiation fins 34 and assuring a clearance between the radiation fins 34 and the forward evaporator cover is eliminated.

Inventor: KURODA SHIGEO
IPC: F04B45/04
Filed: 1989-10-25
Abstract: PURPOSE:To enhance the compression ratio or the exhaust gas ratio, etc., and lessen torque variation for the drive part by allowing the periphery of an eccentric cam to slide on the sliding part of a link. swinging the link, and reciprocating an output rod in the axial direction of shaft. CONSTITUTION:When a shaft 3 is rotated by a motor, eccentric cams 2a, 2b rotate in the condition that their rotational phases are dislocated from each other, and this affects the sliding part 4 of a link 5 to allow it to swing in a plane, and an output rod 6 borne by the link 5 makes reciprocative motion. This enables narrowing the gap between the outer edge of a spacer 30 and the inner edge of bellows 31 to lead to enhancement of the compression ratio.
