Title: Wiring formation method
Inventor: SUGANO YUKIYASU
IPC: H01L21/768
Filed: 1991-09-12
Abstract: PURPOSE:To achieve high barrier property and low resistance of a contact part which has a barrier metal structure. CONSTITUTION:The contact hole 4 opened in an SiO2 interlayer insulating film 3 is covered with a first Ti layer 5 and a TiNx layer 6 in order, and then a wafer is transported by vacuum into an oxidizing atmosphere such as decompressed oxygen, oxygen plasma, etc., and then, it is left as it is. by this oxygen, a thin TiOxNy layer is formed on the surface of the columnar crystal particles of the TiNx layer 6, and also oxygen is segregated in the grain boundary, and the barrier property improves. Inside the crystal particle, TiNx of low resistance remains, so the rise of the resistivity is suppressed as a whole. Since the wafer is not exposed to the air in the cource of the process, defects by the adhesion of moisture to the wafer face can also be avoided. Then, a second Ti layer 7 is formed to complete a barrier metal 8, and the contact hole 4 is filled with an Al-1% Si layer 9.

IPC: C09D5/32
Filed: 1991-09-12
Abstract: PURPOSE:To determine the size and position of an affected region exactly, by writing an index such as a scale or a mark on the surface of an object by using the title paint. CONSTITUTION:X-ray absorbents are selected from among mercury sulfate, barium sulfate, and lead compounds, preferably lead compounds. Various coating materials such as urethane coatings are used. The concentration and thickness of the X-ray absorbent are suitable as far as it can be discriminated clearly on the X-ray film. Namely, the thickness in terms of elemental lead is preferably 10mum or more. An index (e.g. scale or mark) 3 itself appears together with an affected region 6 (R represents mark 4) on the X-ray film of an object 5 having the index 3 written on the surface of the position to be photographed (near the affected region). The size and position of the affected region 6 can be determined exactly, because the index 3 is enlarged or contracted in proportion to the size of the picture.

IPC: G01F1/84
Filed: 1994-10-26
Abstract: PURPOSE: To reduce the influence of mechanical vibration from an external side and improve detection sensitivity to a mass flow rate so as to attain miniaturization by connecting a curved pipe and a linear pipe to each other in a specified form so as to form a measuring part. CONSTITUTION: A measuring part 13 is formed by connecting fixed parts to each other with a linear pipe 13B, a 90 deg. curved pipe 13A, a linear pipe 13D, a 180 deg. curved pipe 13C and a linear pipe 13E. A vibration generator 16 is disposed in the linear pipe 13D and sensors 17 and 18 for detecting Coriolis force produced by the flowing of fluids to be measured to a measuring pipe 10 are respectively disposed in the linear pipe 13B and the curved pipe 13C. Because of the existence of a curved pipe part composed of the curved pipe 13A, the linear pipe 13D, the curved pipe 13C and the linear pipe 13E, compared with a linear pipe type Coriolis mass flowmeter having the same distance between fixed ends, the stiffness of producing vibration is reduced. Thus, by increasing a deforming amount caused by vibration, a signal intensity necessary for measuring is obtained. Further, by using the linear pipe 13B, a vibration frequency is increased compared with a U-shaped Coriolis mass flowmeter.

IPC: G01N29/44
Filed: 1988-10-18
Abstract: PURPOSE:To improve the reliability of the flaw detecting device by providing aerial ultrasonic wave probes which send and receive ultrasonic waves. CONSTITUTION:The aerial ultrasonic wave probes 2, 10, and 11 send ultrasonic waves in the air above the surface of a material 1 to be inspected in parallel to the surface and also receive the ultrasonic waves which are reflected in the air. For example, the ultrasonic wave probe 10 sends the ultrasonic wave beam B2 to a reflecting body (flank of holding mechanism 9) and knows the positions of the ultrasonic wave probe 2 in directions (c) and (d) from the propagation time of the ultrasonic wave beam. The ultrasonic wave probe 11 sends the ultrasonic wave beam B3 to the reflecting body and knows the positions of the ultrasonic wave probe 2 in direction (e) and (f) from the propagation time. Then a distance arithmetic circuit obtains the distance to the reflecting body from the ultrasonic wave propagation times obtained by the ultrasonic wave probes 2, 10, and 11 and the aerial sound speed of the ultrasonic waves. Consequently, the presence position of a defect is known and the reliability of the flaw detecting device is improved.

Abstract: PROBLEM TO BE SOLVED: To be able to judge if the distal end of the needle has been properly inserted into the blood vessel by releasably attaching a receptacle having an over package chamber separated from an interior chamber for receiving air from fluid to the distal end of a cannula portion. SOLUTION: A receptacle 18 is released from the distal portion 19 of a cannula into which the hub of a needle is inserted. Air removing process is undertaken by depressing a bellows portion 26. The air existing in the needle or other fluid distribution device attached to the distal portion 19 of the cannula is exhausted. Then the needle is inserted in the blood vessel. A push button 20 is carried by the fingers of another hand of a user and pulled to the outer or rear side to extend or broaden the bellows portion 26 again to its original position. Thus, the fluid released in the air removing process counter flows or is sucked into a passageway 24 of the cannula. Therefore it is possible to judge if the distal end of the needle has been properly inserted into the blood vessel.
