Abstract: PROBLEM TO BE SOLVED: To attain coding and decoding efficiency similar to that by an arithmetic coding system and to improve considerably coding and decoding speed. SOLUTION: The method is made up of a prediction-setting process, in which multi-value information source is divided into bit planes or level planes, and either of '0' or '1' of each plane is used for a superior symbol, n-sets of consecutive symbols are predicted and the value (n) is set as a predicted bit number run, a prediction result output process where either '0' or '1' signal is outputted as a prediction hit signal when the prediction of a noted series is hit, a succeeding bit string is coded, and the other signal is outputted as a blank signal when the prediction is not hit. A similar prediction-setting process and a similar prediction output process are recursively repeated by using a new reduced prediction bit number smaller than the value (n), when the prediction is not hit for a prescribed number of times.  When the prediction bit, a similar prediction setting process and a similar prediction output process are repeated by using a new increased prediction bit number. Furthermore, in the case of decoding, similar algorithm is applied to decoding.

Title: Method and instrument for measuring surface shape
Inventor: SEKIGUCHI SHURI
IPC: G01B11/24
Filed: 1985-10-25
Abstract: PURPOSE:To simplify structure of a measuring instrument and to measure a surface shape with high accuracy by calculating an angle of inclination with respect to incident luminous flux at a measuring point from a design value of the surface to be measured and calculating the quantity of movement of a mobile rectangular prism corresponding to the angle of inclination. CONSTITUTION:The surface 8 to be inspected is rotated and driven in order with respect to the incident luminous flux 2 but when the design data of the shape of the surface 8 is already known, the angle of inclination of the surface 8 with respect to the luminous flux 2 corresponding to an angle of rotation of the surface 8 can be calculated in advance. When the angle of inclination is denoted as beta, the necessary quantity of movement of the mobile rectangular prism 4 is made 1/2.f.tanbeta, wherein (f) indicates a focal distance of a lens 7 provided at this side of the surface 8. Then, when a digital signal as the necessary quantity of movement of the prism 4 is sent out in order from a CPU 15, the signal is D/A converted 18 via an input buffer 17. An output electric current stabilization circuit 19 excites a coil 20 for driving the angle of inclination in receipt of the analog signal. The coil 20 is fixed on the prism 4 and the prism 4 is moved in accordance with the angle of inclination for every angle of rotation of the surface 8 by the electromagnetic force generating at this time and the angle of inclination can be corrected.

Title: Manufacture of automotive part
Inventor: ISOI MASAAKI
IPC: B29L31/30
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent a flow mark, weld, silver streak, luster nonuniformity, sink mark, a swirl mark and the like from occurring by providing a heat insulating barrier and a surface thin wall metallic layer on the inner surface of a cavity-and/or a core-side part of an injection molding die. SOLUTION: An injection molding die has a heat insulating barrier and a surface thin wall metallic layer formed on the inner surfaces of a metallic cavity-side part and/or a metallic core-side part with which a packed thermoplastic resin comes into contact. That is, a thin wall metallic layer is formed on the internal outermost face of a cavity in the die, and the heat insulating barrier is formed inside the thin wall metallic layer. Under this structure, the surface of a molten resin packed in the cavity is slowly cooled by the influence of the heat insulating barrier and consequently the molten resin hardly becomes set, leaving little chance for a flow mark, silver streak, luster nonuniformity, sink mark or the like to be generated. In addition, when the resin flows join together, their smooth adhesion is ensured, so that a weld line is prevented from occurring. Further, even when a gas is generated near the surface of moldings, the gas is dissolved into the resin by the insulating effects during foaming, so that it is possible to prevent a swirl mark from being generated.

Title: Decontamination method of two-cycle internal combustion engine and related application
Inventor: PIEERU DEYURA
IPC: F02D43/00
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent any pollution caused by discharge of unburned hydrocarbon by oxidizing the unburned hydrocarbon contained in the exhaust gas in the case of two-cycle internal combustion engine. SOLUTION: The present invention is related to a method of delaying injection of fuel into the air used for scavenging the exhaust gas after combustion and further of delaying any early ignition. Owing to this delay, an exhaust gas temperature is increased, and post-oxidation of hydrocarbon not yet burned contained in the exhaust gas is allowed to take place and owing to this post- oxidation, any particular catalyst is not required to be used for exhaust gas. The abovementioned delay may be achieved within the actional range of the regulated number of revolution of an engine.

Abstract: PURPOSE:To suppress the vibration of a line cathode ray by causing the line cathode ray to receive electric force corresponding to a speed from an electric field where the line cathode ray lies and enlarging equivalently the attenuation ratio of a vibration system produced by the line cathode ray. CONSTITUTION:A line cathode ray drive output circuit 53 outputs a pulse signal going to a low level during a horizontal blanking period based on a horizontal pulse. This output pulse signal is applied to an integrator together with a line cathode ray drive pulse (a) from a line cathode ray drive circuit 26, and the output is applied to a line cathode ray 2a. At this time, the line cathode ray drive pulse A impressed to the line cathode ray 2a is modulated so that its horizontal blanking period can go to a low level during a line cathode ray heating period, and an electron beam is emitted at every horizontal blanking period at a low level during the heating period from the line cathode ray 2a. In such as way the electron beam is emitted from the line cathode ray 2a at every horizontal blanking period during the line cathode ray heating period, and the electron beam stream at this time is detected as an electric current by a vertical focusing electrode 3. Thus the vibration of the line cathode ray 2a is detected, and the vibration of the line cathode ray 2a is prevented by subsequent circuits.
