Title: Connecting method for pipe
Inventor: TOYODA HIROYASU
IPC: F16L25/00
Filed: 1989-12-22
Abstract: PURPOSE:To make connection of pipes surely during and after work execution by providing a detecting part, actuated by the pipe inserted to a socket joint, in it and detecting a pipe connection condition by an output of the detecting part. CONSTITUTION:An electrical contact 6 is embedded in a socket joint 1 so as to be closed by pressing of the end of a pipe 2 fitted into the socket joint 1. The electrical contact 6 is housed in a vertical direction inside a partitioning inner flange 1a for pipe stopping of the socket joint 1, when an end face of the pipe 2, inserted into the socket joint 1, collides with this inner flange 1a, the electrical contact 6 is pressed from the outside and closed. An electric signal is confirmed by drawing out the electrical contact 6 outside the pipe 2 by a lead wire or the like. As a result, whether the pipe is mounted in an accurate position and angle or not can be easily confirmed during execution. While inspection can be attained to a minimum limit because the pipe can be surely connected simultaneously with completion of the execution.

Title: Method and equipment for dry etching
Inventor: IZAWA MASARU
IPC: H05H1/46
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To prevent a foreign matters from generating and improve dimensional accuracy of wiring, by etching by supplying a subject with oxygen and carbon so as to have the ratio of the number of oxygen atoms to the number of carbon atoms at a specific limited value. SOLUTION: A region 102 is a region where foreign particles are generated and a range 103 is a ranged of an oxygen/carbon incidence ratio within the tolerance of deviation from a mask size. A curve 101 showing a side etching quantity increases with the increase of the oxygen/carbon ratio. Though the process accuracy depends on the pattern size, it is necessary to reduce the oxygen/carbon ratio to be smaller than a fixed value in order to obtain a sufficient process accuracy, which is approximately over 0% but not more than 10%. When the oxygen/carbon ratio is reduced, the side etching quantity is reduced. However, when it is close to the oxygen-free state, as the deposition of resist, etc., is not suppressed, it deposits in the etching equipment and induces problems of foreign matters and particles.  The side etching quantity is reduced by reducing the oxygen/carbon ratio within a range where foreign material, particles, etc., are not generated.

Filed: 1989-12-26
Abstract: PURPOSE:To detect discontinuity of articles to be continuously transported, earilier and without fail, in order to prevent unnecessary troubles by sensing difference of light amount signals extracted from a pair of areas being set in an sensed image. CONSTITUTION:Articles 2 which are being continuously transported by a belt conveyor 1, are imaged by a camera device 3 and their image signals V are transfered to a signal processing circuit 4. The circuit 4 sets a pair of areas at an arbitraty position within the image frame and puts markers (a) and (b) on the area. Here, the pair of areas are selected from each of upper- and down- stream sides of the line of articles and it is preferable for light-amount signals of the two areas to be equalized when the ariticles 2 are normally transported. Difference of the light-amount signals A and B are calculated by a calculator circuit 6 and then is transferred to a comparator circuit 7 as a light-amount difference signal S. Absolute value of the signal S and a preset reference value St is compared by the circuit 7 and when the signal S comes over the reference value St, an alarm AL is issued assuming the transportation of the articles 2 is discontinued.
