Abstract: PURPOSE:To prevent the interlayer delamination between nonwoven fabric and a base sheet during the use in filter cloth having a dust feed side composed of nonwoven fabric of ultra-fine fibers. CONSTITUTION:In a process forming nonwoven fabric layer made of ultra-fine fibers of 0.5 denier or less on one side of a high-strength base sheet 3, a web of split type conjugate fibers, after being interlaced by needle punching to be integrated with the base sheet. is treated with a flow of high-pressure liquid to split the conjugate fibers so that a filter layer 2 of the ultra-fine fibers is formed.

Title: Check valve structure for diaphragm pump
Inventor: KUSAKA TAKESHI
IPC: F04B43/02
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To provide check valve structure for a diaphragm pump capable of keeping a stable flow rate characteristic without degradation in a sealing property. SOLUTION: In a area which blocks an air hole 21a of an open/close plate 22 blocking the air hole 21a of a valve base 21, a bulge portion 22d bulging to the opposite side to the valve base 21 is provided. Since the size of the area covering an end surface opening of the air hole 21a is enlarged, pressure acting on the above mentioned area through the air hole 21a is dispersed, so that generated stress is made to be small. And by providing the bulge portion 22d, the area is also reinforced. Therefore, the check valve resists deforming against the pressure acting on through the air hole 21a to prevent degradation in a sealing property, which can keep a stable flow rate characteristic.

Title: Printed circuit board
Inventor: DEBUITSUDO DEYUARANDO
IPC: H05K3/24
Filed: 1989-07-06
Abstract: PURPOSE: To form patterned conductive circuit elements having a resistivity of less than 0.05ohms/cm<2> by applying ultrasonic ray pulses to harden the ultraviolet setting resin components of an ultraviolet setting ink. CONSTITUTION: Desired circuit pattern is printed on a nonconductive board with an ultraviolet setting ink and exposed to an ultraviolet ray at a range of 360mm to 420nm such that 5-8 times of this ray for 1/2sec. are repeatedly applied with non-exposure time of about 2-3sec. The ink hardens to shrink the conductive ink film in depth uniformly over the entire depth thereof. This moves grains so as to mutually approach. Thus it is possible to provide a low resistance and form patterned conductive circuit elements capable of carrying a more high operating current.

Abstract: PURPOSE:To prevent a power loss in a rotary joint and the reduction in the gripping force by a centrifugal force by providing a gap on the sleeve inner periphery, forcibly feeding gas and providing a plunger energized by a spring in the rotating radial direction by communicating to a cylinder chamber. CONSTITUTION:When gas is fed from an inlet port 18a, it is injected toward a bearing 10 from the whole periphery of the small gap between a sleeve 5 and rotating center axial part 3, the lubrication oil flowed out of an oil passage 13 is blown off by the injected gas without introducing into the gap and flowed out by passing the bearing 10 inside and the bearing 10 is also lubricated without any power loss. At the time when a work is gripped by the claw of a chuck by feeding a pressure medium to a cylinder chamber 7a, the pressure medium displaces a plunger 24 against a spring 23, stopping it in a balanced state. The pressure medium is sealed by a check valve 16a, the work is gripped and when the chuck is rotated, a cylinder 1 is also rotated and the gripping force is reduced by the centrifugal force, but the plunger 24 is made to compress the pressure medium of the cylinder chamber 7a inside by the centrifugal force and the reduction is eased and it functions as a pressure accumulator even against the pressure fluctuation by the leakage of the pressure medium and temp. change.
