Title: Picture input device
Inventor: EBISU NAOKI
IPC: G06T1/00
Filed: 1993-03-18
Abstract: PURPOSE:To make the image pickup characteristic of the picture input device coincident with an ideal image pickup characteristic of a monitor by using two kinds of positive/negative image pickup characteristics and sensing the same point of an original twice and feeding back a difference between picture data at the time of positive sensitivity and picture data at the time of negative sensitivity to R, G, B outputs. CONSTITUTION:An original 4 is sensed while a 1st color temperature conversion filter 7a is inserted in an optical path and picture data obtained by a color sensor 6 are stored in a memory 10a. Then the filter 7a is replaced with a 2nd color temperature conversion filter 7b and the same point of the original 4 is sensed and its picture data are obtained. Then the two picture data are inputted to an arithmetic operation circuit 10, in which difference data are obtained and they are fed back to R, G, B outputs. Thus, the image pickup characteristic of the picture input device is made equal to that in the ideal image pickup state.

The polymers A, B have ≥ 0.94g/cm 3  density, the density and m.p. differences between them are within 0.3g/ cm 3  and 20°C, respectively, and the total amount of them occupies ≥70wt% of the binder. The mixing ratio of the polymers A, B is preferably 50:50W95:5 by wt. When 10W40wt% hydrophobic colloidal silica is contained in the toner, the mixing ratio may be 5:95W95:5 by wt. This binding resin is also applied to a toner contg. 20W70wt% magnetic powder. Thus, a pressure fixing toner giving a high quality image is obtd.

Title: Refrigerator and circulating method of cold air in refrigerator
Inventor: SHIN JIYUNCHIYORU
IPC: F25D17/06
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To block a backward stream of cold air in a freezing chamber and a main cold air duct into a cold chamber by connecting a cold air return duct to a main cold air duct so as to return cold air drawn in from a fan device through the cold air return duct to the freezing chamber via an evaporator. SOLUTION: Cold air in a freezing chamber 110 is forced to flow into a main cold air duct 140 through a cold air inlet 114 by the rotation of a cooling fan 141. The cold air flows downward along the main cold air duct 140, joins cold air from a cold chamber 120 at the junction with a cold air return duct 131, and passes through an evaporator 137, The cold air performs heat exchange as it passes through the evaporator 137 and is discharged again into the freezing chamber 110 through a cold air outlet 112. As a result, it is possible to block the backward stream of the cold air in the freezing chamber 110 and the main cold air duct 140 into the cold chamber 120 and consequently prevent food in the cold chamber 120 from freezing.

CONSTITUTION:When the malfunction of machines containing a rolling mill 39 at the downstream side of a tilting-type twin-belt continuous casting machine is caused and some replacement is required, the cast billet 40 is cut by a shearing machine installed at the just back of the casting machine. Then, the cast billet 40 being after the shearing machine is fed to the mill 39 and the casting machine is operated without stopping after cutting and the produced billet 40 is wound on a winder. After winding the billet 40 by a prescribed length, the wound billet 40 is cut by the shearing machine at the just back of the casting machine. The wound coil is rapidly moved into a thermally isolated furnace. During that time, casting is continued and the succeeding billet 40 is again wound on the winder. Such an operation is continued and the casting machine is stopped after all of molten metal in the casting machine is cast. After recovery from malfunction of the rolling mill or other some machine, the coil is delivered from the furnace, is rewound by a rewinder, and is rolled.

Abstract: PURPOSE:To provide a purification method capable of readily and accurately controlling the content of heavy metals and sodium sulfide constantly to a low value in comparison with the conventional method and obtaining a high- purity sodium formaldehydosulfoxylate(SFS). CONSTITUTION:An aqueous solution of SFS is synthesized by using zinc, sulfurous acid and formaldehyde as the raw materials and excessive sodium sulfide is added to the aqueous solution to convert heavy metals contained in very small quantities to their sulfides and remove them. The remaining sodium sulfide is subsequently quantitatively analyzed and a metal halide, preferably a chloride, especially zinc chloride, copper chloride or nickel chloride equivalent to sodium sulfide is added to convert sodium sulfide to a metal sulfide and remove it, thus producing the objective high-purity SFS. As the quantitative analysis method of sodium sulfide, e.g. a colorimetric analysis in which color development by a reaction with an alkaline lead acetate is utilized, a method carried out by reacting an acid thereon and analyzing generated gaseous hydrogen sulfide and an ion electrode method are exemplified. The colorimetric analysis or the ion electrode method is preferably used from the viewpoints of, e.g. simplicity of the analysis and applicability to an on-line measurement.

Abstract: PROBLEM TO BE SOLVED: To provide a heat transfer controlling device that can effectively utilize heat by varying the thermal conductivity between heat transmission and reception. SOLUTION: Between an internal container and an external container 12, a Peltier element 13 and a means 14 for changing thermal conductivity are provided. In the means 14 for changing thermal conductivity, magnetic fluid 22 is encapsulated to a closed case 21, and a coil 24 for generating a magnetic field in the magnetic fluid 22 is provided.

Title: Optical head
Inventor: DOI AKIHIKO
IPC: G11B7/09
Filed: 1985-04-23
Abstract: PURPOSE:To simplify structure and adjustment by shifting a light source block that emits luminous flux passed through a condenser as converged light and thereby changing the angle of incidence of the luminous flux. CONSTITUTION:When a light source block 21 that emits luminous flux L passed through a condenser 21b as converged light is put away from an objective 25, flux of laser light L passed through the lens 25 is converged at a position approached the lens 25. When the block 21 is brought near the lens 25, flux of laser light L passed through the lens 25 converges at a position off from the lens 25. That is, by shifting the block 21 in the direction of optic axis, angle of incidence of flux of laser light L that enters points at equal distance from optic axis on the lens 25 changes, and thereby, the position at which flux of laser light L is converged by the lens 25 moves back and forth in the direction of optic axis. Accordingly, when a medium 22 approaches the lens 25, focused state can be maintained by bringing the block 21 close to the lens 25, and thus, structure and adjustment can be made simple.

Title: Device for detecting intake air flow in internal combustion engine
Inventor: MIZUNO KAZUYOSHI
IPC: G01F9/00
Filed: 1981-06-05
Abstract: PURPOSE:To perform the highly accurate measurement regardless of the amount of the intake air flow, by using a potentiometer and the like having at least two sliding contact points, and decreasing relative errors when the amount of the intake air flow is detected. CONSTITUTION:The output voltages from sliding pieces 22, 24, 26, and 28 are selectively taken out in response to the signal from an encoder which is displaced with a rotary shaft of a measuring plate 10 and generates a binary  signal. A/D conversion is performed on said voltages and a factor is multiplied on the result. Thus the final detected value of the amount of the intake air flow is obtined. In this way, the voltages, whose full scale ratios with respect to the specified angle displacement of the measuring plate 10 are different and the voltage values themselves are different, are generated at the sliding pieces 22, 24, 26, and 28. Therefore the relative errors of the potentiometer 16 and the like with respect to the same amount of air flow are different. By selecting the output voltage of the sliding piece having the small relative error, the amount of  the intake air flow can be measured highly accurately.
