摘要： PURPOSE:To improve etch factors by incorporatin a process of forming a chemical resistant film by photographic techniques on side etching surfaces at the time of forming said film on non-worked parts and perform etching. CONSTITUTION:The surface of a metal 1 formed with a chemical resistant film 2 by photographic techniques is etched to a permissible limit of rate of side etching. Next, the 2nd, for example, positive type photosensitive chemical resistant film 3 is formed over the entire surface of the metal 1 surface in the same manner as mentioned above, after which the rays R parallel to the thickness direction of the metal 1 are applied and the film is developed, whereby side etching preventive films 4 remained by becoming non-photosensitive and insoluble are formed. Thence, etching is resumed, and before it arrives permissible limit of the rate of side etching, the etching is interrupted. The above-mentioned ethcing operation is repeated until prescribed working depth is obtained. Thereby, an etch factor B/A is made extremely large.

摘要： PURPOSE:To perform high-precision adjustment by automatizing the measurement of overpin dimensions. CONSTITUTION:A main control device provided with a signal processing arithmetic unit, a printing device, display device and an auxiliary control device is placed between measuring probe 1 and a drive unit. By this, electrical signal which shows the amount of displacement of measuring probe 10 advancing into groove 11 of the gear, an amount of displacement which has been formed on work 1 in accordance with the signal sent from the main control device, is fed to the signal processing arithemtic unit, and thereby the overpin dimensions which determine the thickness of gear formed on the work are automatically calculated, and the results are sent to the printing device, the display device and the auxiliary control device. Further, the drive unit, which adjusts the distance between hob 5 and work 1, operates on the basis of the difference between the overpin dimensions calculated by the auxiliary control device and the theoretical overpin dimensions. Consequently, personal errors due to human operation are eliminated.

摘要： PURPOSE:To obtain superior holding power and airtightness by inserting a pipe which has beforehand been fitted with rings on the outside circumference into the hole of a pipe plate and expanding the same. CONSTITUTION:A pipe 2 which has been inserted with rings onto its outside circumference is inserted into the hole of a pipe plate 1, and an electromagnet forming coil 5 is disposed in the pipe 2 concentrically to the pipe 2. Thence, when large current is supplied to the coil 5 from an electric source, not shown, a magnetic field is generated, and a magnetic field of antiphase by the induction current is generated in the pipe 2, by which the pipe is expanded. The rings 4 penetrate in the pipe plate 1 and the pipe 2, thus good holding power and airtightness are obtained.

摘要： PURPOSE:To perform electrospark cutting smoothly and speedily by a method wherein a cutting electrode suspended by a rope is moved slidably by its own weight into a positioning device to which an article to be worked is fitted in the cutting by remote control of an article to be cut positioned in a place hard to approach such as the bottom of water. CONSTITUTION:A positioning device 11 being provided near an article to be cut 10, the compressed air is sent to an air hose 8, air cylinders 18 and 18' of the positioning device 11 are extended and shortened, and thus the article to be cut 10 is positioned, while the compressed air is sent to an air hose 8', a rear cylinder 20 being extended and thus an earth 23 for electrodischarge being pressed on the article 10. After the article to be cut 10 being positioned in this way, a rope 3 for sending an electrode is let out through the intermediary of a pulley, an electrode 25 for cutting is lowered gradually by its own weight along a slide space between the shank members 13 and 13' of the positioning device 11 and is brought near to the article 10, and thus the electrospark cutting is applied to the article to be cut 10 under the water.
