Abstract: PURPOSE:To extract high ion current in a low accelerated voltage by shortly and uniformly keeping the inter-grid distance that accelerates the ions generated from an ion generation chamber. CONSTITUTION:A grid 11 uniformly forms an insulating film 13 made of such as SiO2, Al2O3 on a conductive substrate 12 made of such as an Si single crystal and then a metal thin film 14 made of such as Ti and Cr on it. Then, a hole section 15 for extracting ions in which a great number of holes 151-15n penetrating into a substrate 12 through the insulating film 13 from the metal thin film 14 are perforated is formed between the substrate 12 and the metal thin film 14. In an ion beam etching device, such a grid is arranged between an ion generation chamber A and a neutralizer 7. Ions can be accelerated and extracted from the ion generation chamber by applying preset voltages using the conductive substrate 12 as a screen grid and the metal thin film 14 as an accelerator grid. Besides, the substrate 12 and the metal thin film 14 can be held at an extremely short preset spacing.

Abstract: PURPOSE:To permit the amount of light to be taken to be regulated by limiting the amount of light according to the angle of incidence by a method in which two kinds of polarizing regions having different polarization characteristics are formed on one side of a light-transmissive base plate and also on even the other side. CONSTITUTION:The first polarizing region 121 is formed on one side of a light- transmissive base plate 11 set to interrupt the path of natural lighting, and the second polarizing region 122 having a polarization characteristic different from the region 121 is formed close to the region 121. The third polarizing region 131 is also formed on the other side of the plate 11 and the fourth polarizing region 132 having different polarization characteristic is formed close to the region 131. The amount of lighting is adjusted by limiting the amount of natural lighting according to the angles of incidence. Since a natural lighting device 10 is integrally made up of the base plate 11, the structure can be simplified, handleability can be raised, and the versatility of forms can also be enhanced.

Filed: 1993-04-27
Abstract: PURPOSE:To prevent filters from being damaged by melting in the case of regeneration by providing three filters in an exhaust passage, making two out of three filters in the collecting state, and making the other filter in the collecting state when two filters are regenerated. CONSTITUTION:Three filters 5A to 5C are provided in an exhaust pipe 2 of a diesel engine. Normally, two filters out of three filters 5A to 5C collect particulates, and the inflow of exhaust gas to the other filter is shutted off. When two filters are regenerated, the inflow of exhaust gas to two filters are shutted off, and exhaust gas is made flow into the other filter, so as to become in the collecting state. In this state, two filters wherein the flow of exhaust gas is shutted off are alternately regenerated. Thus, the excessive collection of particulates is not performed in two filters and the other filter, and all filters are properly regenerated, so that the filters may be prevented from damages by melting.

Title: Rim rotating for itself
Inventor: NAGATA TETSUKAZU
IPC: F03B17/02
Filed: 1979-08-08
Abstract: PURPOSE: To produce turning force by utilizing buoyancy, gravity and magnetic force so that a weight difference is produced between the right and left sides of spokes of a rim.  
     CONSTITUTION: Into several arms 2 directly connected to a rim 1, a liquid 3 and floats 4 capable of moving in the arms 2 are put. Almost semicircular magnetic belts 5 are attached to the outside and the center of the rim 1 so as to face each other. The floats 4 contain rion powder 7 much enough for the magnetic force of the magnetic belts 5 to help the floats 4 to float together with the help of the air in the floats 4. Thus, some floats 4 on the side of the semicircular magnetic belt 5 attached to the outside of the rim 1 are made to be located toward the outside by the magnetic force. On the other hand, other floats 4 on the side of the semicircular magnetic belt 5 in the center are made to be located toward the center by the magnetic force of the magnetic belt 5 attached to the center. Consequently, the difference between the weights of the arms 2 of both portions permits the rim 1 to rotate clockwise in the figure. In addition, the position of each float 4 is shifted to the opposite side by the buoyancy of the air when the float 4 passes the magnetic field and is released from the magnetic force.
