Title: Perforation
Inventor: RIYUUKOU YOSHIHIRO
IPC: B23P17/00
Filed: 1980-07-01
Abstract: PURPOSE: To facilitate a process of perforating a large number of holes having uniform opening size by forming, in tops of ridges in large numbers provided on one surface of a material, slits having a depth greater than the wall thickness of the tops.  
     CONSTITUTION: A large number of ridges 2 are formed on the lower surface of a matrial 1 at suitable intervals, while grooves 3 are formed in the upper surface of the material, corresponding to the ridges 2. Then, slits 5 are formed in the top 4 of each ridge 2 by a cutter such as for example rotating disc saw or grinding cutter, which is cut into the top 4 of the ridge 2 to a depth greater than the wall thickness of thereof, and is moved along the surface of the material 1 toward the subsequent ridges, sequentially.

Title: Air cleaner
Inventor: OKUHARA SHINJI
IPC: B03C3/40
Filed: 1995-03-23
Abstract: PURPOSE: To provide an air cleaner capable of stopping a supply of electric power when a high voltage more than a prescribed value is applied on a floating electrode. CONSTITUTION: A distance between a counter electrode 13 and the floating electrode 23 is made close (T1) at a part more than the other parts. When a discharge electrode 11 is cut by some cause and brought into contact with the floating electrode 23, the voltage of the discharge electrode is impressed to the floating electrode 23, but since a spark is easily generated because of a short distance between them at some part, overcurrent breaker 27 is actuated by the generation of the spark and a power supply from a power source is stopped. Therefore, the overcurrent is prevented from flowing to collector plates 17 and 19 to prevent heat generation, damage, etc.
