Filed: 1993-04-27
Abstract: PURPOSE:To obtain a stable picture image even at high temp. and high humidity by incorporating a specified amt. of specified ethylenevinyl acetate copolymer having specified melt flow rate and containing specified amt. of vinyl acetate into a binder resin essentially consisting of thermoplastic polyester resin. CONSTITUTION:The binder resin essentially consisting of thermoplastic polyester resin contains 5-50wt.% ethylene-vinyl acetate copolymer having >400g/10min melt flow rate and containing 3-30wt.% vinyl acetate. If the melt flow rate is smaller than 400g/10min, the melt viscosity increases and the resin does not flow enough at low temp. so that low temp. fixing can not be done. If the amt. of vinyl acetate is less than 3wt.%, the toner easily causes aggregation. If the amt. exceeds 30%, the glass transition temp. decreases. If the amt. of the ethylene-vinyl acetate copolymer is less than 5wt.%, the effect is not obtd. If it exceeds 50wt.%, the compsn. becomes tough so that it cannot be finely pulverized into a toner.

Abstract: PURPOSE:To obtain a good combustion characteristic, and also prevent the blow-off intact fuel in an exhaust system to improve a fuel consumption rate by previously injecting fuel into an auxiliary chamber in which fresh air is introduced, and promoting mixing and atomization at the point of time of blowout into a combustion chamber. CONSTITUTION:Fuel is injected into an auxiliary chamber 7 from a fuel injection valve 9 and also a communication passage 6 is opened with an auxiliary valve 8 in the initial stage of a compression stroke for rising a piston 3, that is, at the vicinity where a scavenging port 10 is closed with the piston 3. Consequently the fuel, mixed with fresh air previously introduced into the auxiliary chamber 7 from a branch passage 15 to be atomized, is blown out in a combustion chamber 4. Opening an exhaust port 11 with the piston 3 in the latter half of a combustion stroke causes starting the discharge of a burnt gas and extruding the burnt gas by the fresh air introduced with the opening of the scavenging port 10. Meantime with the rising of the piston 3, the auxiliary valve 8 is opened to blow out the fresh air in the combustion chamber 4, via the auxiliary chamber 7 from the branch passage 15, together with the fuel from the fuel injection valve 9.

Filed: 1988-04-25
Abstract: PURPOSE: To prevent a drop in real density of picture image on memory medium lower than nominal density by letting address-designated record location form a near-continuously adjacent population and groups in each dither cell distribute substantially at random. CONSTITUTION: Incremental sequence distribution of successive reference values of groups in dither cell is nearly at random, and reference values of record locations in a group have been so arranged that the upper left is the least reference value and adjacently rising in succession therefrom. With increase in color density determined with specific combination of hue and degree of saturation, accordingly, groups in the dither cell are addressed nearly at random, and record locations in specific groups are regularly addressed so as to neighbor in succession. Consequently, picture image of print region in each group is formed with continuously contagious points only. According to this, influence of blur, aberration and the like of points printed on record medium can be reduced in comparison with the dither pattern in the past.

Title: Correcting method for base line
Inventor: FUKUMA TOSHIAKI
IPC: G01J3/28
Filed: 1981-06-30
Abstract: PURPOSE:To shorten a time for operation of a correction value and reduce a memory capacity by a method wherein the difference between base line correction values at the starting points of counting which are measured beforehand and stored in a memory is shifted by (n) digits to compute a correction value of an intermediate point. CONSTITUTION:A computer Cp controls the scanning of wavelengths by a spectroscope M in a spectroscopic analysis or the like. When some starting point is reached, a memory (m) is accessed, and base line correction values at the starting point and the following starting point are read out. Then, a binary information on the difference between the two correction values is shifted by (n) digits to be one 2n-th without division by the computer Cp, and thereby an unit correction value to be added sequentially to an intermediate point between the two starting points is decided and stored in a specified address in the memory (m). By the abovestated method wherein no division is required and a subtraction and an addition alone are used, a time for operating the correction value is shortened, and since all intermediate base line correction values need not be stored, a memory capacity can be reduced.
