Title: Powdered rubber having many hollow parts and its production, powdered rubber and its production, adsorbent of oil and solvent
Inventor: FUJI MICHIHARU
IPC: B29K105/24
Filed: 1994-07-21
Abstract: PURPOSE:To enable vulcanized powdered rubber to be used for the absorbent of a solvent and oil by equipping many hollow parts on the surface of the vulcanized powdered rubber and to enable the vulcanized powdered rubber to be suitably used for oil spill in the sea and a river by floating the vulcanized powdered rubber cohered in a ball-shape afrer absorption in water. CONSTITUTION:Powdered rubber having many hollow parts is produced by equiping many hollow parts on the surface of vulcanized powdered rubber. Various kinds of rubber are used and both butadiene rubber and nitrile butadiene rubber are used as the representative example. In general, particle diameter of the powdered hollow rubber is regulated to about 200-700mum and bulk specific gravity is regulated to 0.15-0.3-g/cm<2>. In the powdered hollow rubber, absorbability of a solvent and oil is excellent. The solvent is absorbed at about ten times of the weight and oil is absorbed at about three times of the weight. Even when the particle diameter is large, oil is absorbed at about two times of the weight. Further, since the bulk specific gravity is smaller than 1.0, the powdered hollow rubber floats in water and is suitably used for an oil absorbent in an oil spill accident in the sea and a river.

IPC: F16C33/10
Filed: 1987-07-31
Abstract: PURPOSE:To achieve good lubrication through a quite short aging by forming a phosphate film on the surface such that it will provide lubrication and plastic fluidity when a bearing slides on a shaft. CONSTITUTION:At first, material powder is mixed then mixed material powder is molded into a specific bearing shape and burnt. Then burnt metal is subjected to formation so as to form a fine and uniform phosphate film on the surface of a bearing through forming liquid. The phosphate film is formed on the entire face when ferrous material is employed while formed on an exposed portion when mixed powder of iron and other metal is employed. The bearing formed with phosphate film is subjected to improvement of surface treatment and correction under sizing process, then the porous bearing is impregnated with lubricant and finished. The phosphate film formed at the inner diameter section of the bearing provides lubrication and plastic fluidity when the bearing slides on the shaft, thus realizing best hydraulic pressure distribution in short time.

Title: Method for automatically generating test vector
Inventor: OSAME TOSHIKI
IPC: G06F17/50
Filed: 1993-07-09
Abstract: PURPOSE:To automatically generate a test vector which can test a circuit containing an FF having no scan-path constitution by calculating such a probability that the logical value of input signals becomes '1' by regarding the FF as a one-input, one-output buffer. CONSTITUTION:Upon receiving a logical network list, processing is started. The probability that the logical value of input signals becomes '1' at which a cost function becomes the minimum is calculated and the probability is used as the weight of a random number. Then, a test vector following the weighed random number is generated. By performing fault simulation, the test vector is inputted to a virtual logic circuit on a computer and simulated fault detection is performed to calculate a fault detecting rate. When the fault detecting rate does not reach a target value, another test vector is additionally prepared to detect the faults which could not be detected by the previously prepared test vector and similar processing is repeated. After the fault detecting rate reaches the target value, the test vector preparing process is completed by eliminating the test vector which did not contribute to the improvement of the fault detecting rate from the prepared test vectors.

Title: Vibration damper having adjustable cushioning force
Inventor: ANDOREASU FUEESHIYUTAA
IPC: F16F9/46
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To reduce the space requirement of a damping valve device by directing a sidestream in its front-stage valve, related to the direction of flow, through a control cross section and a check valve that opens in the direction of flow. SOLUTION: For movement of a damping valve device 1 in a direction A, a damping medium is divided inside an inlet opening 15a into a mainstream and a sidestream that flows into a control chamber 19a. A control cross section 39a creates in the control chamber 19a such pressure as applies closing force to a main-stage valve element 21a. Opening force in the area of the inlet opening 15a larger than the closing force within the control chamber 19a opens an inlet part 13 to a connection passage 11. The control chamber 19a is drained via an adjustable front-stage valve 23 and a check valve 31a so that the sidestream flows out via a valve 37b related to the direction of flow. In the stroke movement, a check valve 29a closes the connection passage 11.  For stroke movement in a direction B, the sidestream flows out via a second control chamber 19b and the mainstream flows out into the connection passage 11 owing to a lifted main-stage valve element 21b.

Abstract: PURPOSE:To provide an alternate two-way repeater independent of data to be transmitted by constituting the repeater of a simple circuit without using a CPU mainly in optical communication. CONSTITUTION:An electric signal inputted to a delay IC 6a in a single way repeater part s1 is delayed by a delay time dt and inputted to an AND gate 7a.
