Title: Catalyst converter for automobile
Inventor: SHIMOJI KOUJI
IPC: F01N3/28
Filed: 1981-06-25
Abstract: PURPOSE:To prevent the chipping off of a catalyst carrier effectively by a method wherein a ring-like buffer plate is provided along the outer peripheral edge of the front end surface of the catalyst carrier. CONSTITUTION:A ring-like buffer plate 30 made of paper, resins or wire meshes is provided between the outer peripheral edge of the front end of a catalyst carrier 12 and the shoulder 104 of a case 10. The buffer plate 30 is not in direct contact with the front end surface 121 of the carrier 12 and the case 10 so that the carrier 12 is not chipped by the vibrations of the engine of an automobile or by an external force applied on the buffer plate 30 at the time of its assembly. Further, in case where the buffer plate 30 is made of paper or resins, it disappears due to the heat generating during the travelling of the automobile but the clearance between the front surface 121 and the shoulder 104 of the case 10 performs the function of preventing an exhaust gas from passing through the out er periphery of the carrier 12 of passing around the carrier 12 so that the carrier 12 is prevented from being damaged since the size of the clearance up to 3mm. does not make any difference from a contact condition.

Title: Apparatus and method of extracting liquid from water containing substance by compression
Inventor: ADORIAN BAABURUSUKU
IPC: B30B9/02
Filed: 1983-06-01
Abstract: The present invention relates to a system and a method of extraction liquid from a humid mass by compressing same. The system comprises a conduit of linear, circular or other shape through which the humid mass is displaced. The conduit is of rectangular cross-section, which cross-section can be constant or variable. Further, the conduit has perforated side walls along at least a liquid extraction working section of the conduit. The system further comprises elements which cause an axial pressure at the interior of the humid mass as well as a mechanism to displace at least one of the perforated side walls to convey the humid mass along the working section of the conduit in such a way as to generate between the interior surface of the perforated side walls and the humid mass a dynamic friction force which defines a pressure zone which is less than the axial pressure created by the pressure creating elements. This difference in pressure causes the liquid in the humid mass to flow out of the mass in a direction substantially transverse to the displacement direction of the humid mass and out through the perforated side walls of the conduit.

IPC: H03M11/22
Filed: 1983-06-03
Abstract: PURPOSE:To reduce the size of a semiconductor chip and cost by connecting each switch to at least >=3 different signal lines at a time in an operation mode. CONSTITUTION:Many key switches Sy are provided together with signal lines 1-k and connected to three signal lines via three contacts respectively. When the switch Sy is operated, the three signals lines connected to the operated Sy are short-circuited with each other. The way of combination of these short-circuited signal lines are different for each switch Sy. Therefore, the information showing the operated switch Sy is outputted from each of the lines 1-k. This information can be converted into the codes showing characters or marks by an encoder EC for example. Thus it is possible to output the information related to the operation states of many key switches with a small number of signal lines reduced as much as possible. Thus the size of a semiconductor chip, for example, can be reduced.
