Title: Polishing end point detecting method, polishing equipment and semiconductor device
Inventor: YAMAMURO TAKASHI
IPC: B24B37/013
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a polishing end point detecting method which easily and precisely detects the end point of polishing. SOLUTION: Step-difference is generated on a polysilazane film 33 and an insulating film 34 which are deposited in order and formed on a metal wiring 32, and flattening is necessary. For flattening, a wafer 3 is polished from the side of the insulating film 34, by using abrasive agent containing solvent having hydroxyl groups. When polishing is progressed, the surface of the wafer 13 is flattened, and the surface of the polysilazane film 34 is partly exposed at last. Then ammonia gas is generated by chemical reaction of the solvent and the polysilazane film 33. The generated ammonia gas is detected by a detector, and the gas generation is set as the reference for the end point of polishing.

Title: Production of pipe made of synthetic resin and equipment therefor
Inventor: KOE TETSUO
IPC: B29C53/58
Filed: 1990-02-22
Abstract: PURPOSE:To easily produce a pipe made of synthetic resin which is free from torsion and wavy phenomena and has stable quality by winding a tape along the prescribed virtual helix different in the diameter of winding and tightly sticking the wound adjacent tapes with each other and winding the tape at the nearly same angular velocity in a range over the axial direction of the virtual helix. CONSTITUTION:Carrier force is imparted to the direction orthogonal to a feed roll 7 by a driving roll member 11 in the base end side of a feed roll 7. A tape 2 is sent to the axial direction while it is sent to the circumferential direction of an axis winding mechanism 3. Then this tape 2 is wound one round on the outer circumference of the said mechanism 3. The tip of the tape 2 is pinched between the tape 2 of a second round and the feed roll 7 so that one part thereof is overlapped on the inside of the tape 2 of the second round. Thereby the tape 2 following the second round is supplied so that one part is overlapped on the tape 2 one round earlier. At this time, the overlapped part of the tape 2 following the second round and the tape 2 one round earlier is heated by a heater and melt-stuck. Thereby a pipe 20 having large diameter is continuously produced.

Abstract: PURPOSE: To achieve higher reliability by using pipe-form insulation coverings.  
     CONSTITUTION: Lead wires 4, 5 having insulation coverings composed of vinyl chloride or the like are connected, by way of connection parts 2, 3 which are respectively brazed or silver-brazed, to the terminal leads led out to the both sides of a temperature sensing thermistor 1.

Abstract: PURPOSE:To eliminate an unnecessary image and display only the normal image of a defect part sharply, by displaying the image of the defect part in the inside of an object to be examined with high resolution by the use of an aperture synthesis method and changing the frequency of a ultrasonic wave at every measurement point. CONSTITUTION:The ultrasonic waves differing with each of plural measurement points X1,X2...Xn are irradiated from a probe 101 in the range spreading in a circular conical shape toward the inside of an object 102 to be inspected. The probe 101 receives the reflected waves from the point A at the points X1,X2... Xn and transmits the signals thereof to respective processing circuits 106-1... 106-n for aperture synthesis signals. Thereupon, the circuits 106-1...106-n convert the signals from the probe 101 to image signals and output said signals to memories 107-1...107-n. The image signals made with the circuits 106-1...106-n are inputted to a processing circuit 108 for addition of images, by which said signals are added. The periods of the image signals in this stage differ from each other; therefore, only the normal images having no unnecessary images are displayed sharply on an image display 109.
