Title: Screw compressor
Inventor: ISHII MASAHARU
IPC: F04C18/16
Filed: 1979-07-11
Abstract: PURPOSE: To obtain different capacites in the same compressor by providing notches on the teeth of a rotor on the end-face of the suction side to connect neighbouring spaces and changing the suction timing of operating fluid.  
     CONSTITUTION: In the illustrated example, the number of teeth of a male rotor 1 is four (an even number), and two teeth 11 and 13 are provided with notches 7 symmetrically about the axis of the rotor. When teeth 12 and 14 without notches 7 pass a suction port, the capacity is of about 100%, and the suction port is closed. Meanwhile, when teeth with notches 7 pass the suction port, even if the suction port is closed, compression is not started, and the capacity is reduced to about 80%. Consequently, since two teeth with and without notches respectively pass the suction port in every rotation, the capacity can be reduced to about 90%. In this construction, when the number of notches is adjusted, the capacity can be obtained optionally in about 100W80%.

Title: Non-clogging type mixer for catalytic reaction
Inventor: SAKANO NOBORU
IPC: B01J19/24
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To provide a mixing container for catalytic reaction which is free from a short pass and works efficiently by forming the interior of a mixer for catalytic reaction of a material having a catalytic action. SOLUTION: A mixing container for catalytic reaction has a pillar shape or a polygonal pillar shape formed of a catalytic matter. On the internal side of the container, a tongue-like protrusion is protruded out of the upper and the lower wall surface. This pillar or polygonal pillar with the upper and the lower tongues 1, 2 is made as a single block. A number of the blocks are connected to each other in such a manner that these are shifted at an arbitrarily selected angle. Thus, it is possible to adjust the chemical reaction rate, the catalyst strength and the mixing accuracy. A reactive liquid passing through theses blocks is subjected to such effects as shearing, dispersion, vertical current and reversion without a short pass phenomenon, so that a perfect catalytic process is achieved. Consequently, a device applicable to the catalytic reaction area is realized which reduces the size of a chemical reaction system, is free from a catalyst leakage and is easily maintained in the best operating state.

IPC: B42D15/10
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To reduce the gloss and mat the surface of the printed ground without corroding a thin metal film layer and consequently improve the visual recognizability and storage durability of printed-letters by a method wherein a ground layer is prepared by being interspersed with minute regions made of an incompatible resin. SOLUTION: A slip A is constituted by laminating a colored layer 2, a barrier layer 6, a ground layer 3, a thin metal film layer 4 and a protective layer 5 in the order named on a base material 1. In this case, the ground layer 3 is turned into a sea-and-islands structure by interspersing minute regions made of an incompatible resin in the ground layer 3 by applying a material prepared by dissolving the incompatible resin in a solvent on the barrier layer 6 or the colored layer 2 and then being dried. The forming state of the thin metal film layer becomes different in every minute region from the other at the formation of the thin metal film layer 4 on the ground layer 3, resulting in reducing the gloss of the thin metal film itself and realizing matting.  As a result, when printing is executed on a slip A having a printing layer, in which the above- mentioned ground layer 3 is provided, the gloss of the surface of the printed ground is reduced and matted.
