Abstract: Abstract of the Disclosure A drainage device having a collection chamber for receiving liquids and gases from the body of a patient, an underwater seal chamber and a one-way outflow valve is disclosed.  A partition extending across a portion of the device forms the underwater seal chamber, which prevents the flow of atmospheric air from the device into the pleural cavity of the patient, above the partition and the collection chamber below it.  The underwater seal is created at the lower end of an extension connected to the inlet to the device by liquids drained from the patient.  The one-way outflow valve communicates with a trap chamber for collecting liquids inadvertently conducted toward said valve.  The trap chamber is closed off from the underwater seal chamber but is connected to the collection chamber by means of a passageway through a wall separating the trap and collection chambers.  The novel device has little or no liquid contact with the one-way outflow valve and consequently reduced mechanical malfunction.

Abstract: Abstract:    A cellular type robot apparatus consists of a plurality of robot cells each having intelligence.  Each cell controls its own operation on the basis of information exchange with adjacent cells  The operations of the cells as a whole are coordinated, and each cell can be controlled without a need to change hardware or software, even when one or more of the cells are out of order or when the robot needs to be expanded.  Each cell has arms corresponding to hands and feet and can control its own operation.  As the cells are connected and combined through transmission routes so as to be able to exchange information, they can operate cooper-atively as a group to perform a manipulative action.  The operation of the group can involve determining the shape of a predetermined pattern or can involve entwining an object and gripping and moving it.

Abstract: ABSTRACT:             A method of manufacturing a semiconductor device, in which semiconductor circuit elements are provided in regions (6A,7A,11A) formed by diffusion from one or more buried layers (6,7,11) in an epitaxial layer (13).  Accord-ing to the invention, the diffusion is carried out in a manner such that a surface layer (13A) having substantially the same doping as the original epitaxial layer (13) is left above the buried layer or layers, which surface layer serves as a reference doping for the insulated gate field effect transistors to be formed.  This is of particular important for threshold voltage determination in CMOS circuits having adjoining "twin tub" regions (6A,11A) diffused from buried layers of opposite conductivity types.

Abstract: Abstract of the Disclosure Corner Tooth For A Bucket A corner tooth is useful, for example, on construction equipment buckets to protect the sidewalls from abrasive wear which normally results from continued contact with the ground.  In order to protect the sidewall, others use elements secured directly to the sidewall or various forms of specialized teeth mounted on the corner.  Many of these specialized teeth inhibit the tooth's ability to penetrate the ground.          The present corner tooth provides the protection for the sidewall while still maintaining good strength and penetration.  This is due to a single flat member being oriented vertically with respect to the normal working position of the tooth and a single reinforcement rib extending perpendicular to the flat member.          Furthermore, since the tooth is symmetrical about the second plane and the rib is located along the second plane the tooth can be used on either corner.  This eliminates the need to manufacture and stock an extra part of a different design. Furthermore, once the part is installed, it remains in the same location for its entire useful life thus eliminating down time to change the tooth from one corner to the other.
