Title: Image forming device
Inventor: HOSAKA AKIHITO
IPC: G03G9/083
Filed: 1986-06-05
Abstract: PURPOSE:To simultaneously attain reciprocal effects of the use of a toner having minute particle size and the prevention of flocculation of the toner by using a one-component conductive magnetic developer as the developer and using toner particles having <=10mum particle size and setting the percentage of magnetic materials in toner particles to >=30wt%. CONSTITUTION:With respect to the developer, the one-component conductive magnetic developer is used, and toner particles having <=10mum particle size are used and the percentage of magnetic materials in toner particles is set to >=30wt%. Though the size of the developed image of a dot is equal to that of a dot latent image in case of the use of toner particles having <=10mu particle size at normal temperature and normal humidity, the developed image is larger than the dot latent image and the resolution is degraded and the density is insufficient if the particle size of toner particles is larger than 10mu. At a high humidity, toner particles are flocculated and pictures of high resolution cannot be attained in case of magnetic toner particles having <=10mu particle size.

Filed: 1982-07-26
Abstract: PURPOSE:To obtain a magnetic recording medium having high coercive force, high magnetic flux density and high stability by as much as suppressing addition of the ferrous ion (Fe<2+>). CONSTITUTION:The needle-crystallized gamma-Fe2O3 etc. is sufficiently dispersed into the cobalt salt aqueous solution. This dispersive solution is mixed with a reducing agent such as the hydro-sulfite, boron sodium hydroxide, hydrazine, derivative of hydrazine and sodium hypophosphite etc. and the alkali solution in order to trigger the reducing reaction. Thereafter, this mixed solution is heated with a temperature of almost 100 deg.C or lower for the purpose of reaction. Thereby, the cobalt compound is deposited on the surface of corpuscules of needle- crystallized gamma-Fe2O3 etc. When reaction comes to the end, the deposited material is washed by water and it is collected as the magnetic powder by filtering and then dried up. The magnetic recording medium obtained thereby shows the characteristic that the coercive force at a temperature of 25 deg.C is 550 oersted or more, a ratio of the coercive forces at the temperatures of minus 190 deg.C and 25 deg.C is 1.8 or less, content of Fe<2+> included is 1.0wt% or less, orientation degree is 2.0 or higher.

Title: Combined power plant
Inventor: KUSAKA IWAO
IPC: F28B9/00
Filed: 1989-05-25
Abstract: PURPOSE:To shorten the time of manipulation of start of a power plant unit without the use of complicated system by returning condensate water which has been transferred into a reserving tank insulated from the atmosphere during stop of the unit, at the time when the vacuum increases before the start. CONSTITUTION:Upon stop of a unit, condensate in a condenser 6 is transferred into a reserving tank 51 before vacuum break of a condensate pump 7. Thereby the condensate pump 7 is stopped to give a vacuum break. Thereafter, the degree of vacuum of a condenser 6 is raised during start thereof up to a predetermined value, and thereafter, shut-off valves 52, 53 are opened so as to automatically lay water in the condensor 6 without driving the other drive pump. With this arrangement, condensate may be returned to the condenser 6 in a low dissolved oxygen concentration condition without being exposed to the atmosphere, thereby it is possible to restart the unit in a short time without using deaeration.

Title: Polyphenylene sulfide resin composition
Inventor: OTSU MASAAKI
IPC: H01G2/10
Filed: 1985-06-15
Abstract: PURPOSE:To obtain a resin composition low in a content of free electrolytic impurities, by using a polyphenylene sulfide resin having a specified average particle diameter as a component. CONSTITUTION:A polyphenylene sulfide (PPS) resin composition having an average particle diameter of 1-20mu. When the average particle diameter of said PPS resin is smaller than 1mu, it is inconveniently handled in washing, filtration, transportation, etc. On the contrary, when it is larger than 20mu, it is impossible to remove impurities inside even by repeated washing and extraction operations because of the excessively small surface area of the polymer, though it is possible to remove impurities adhering to the surface. Therefore, it is difficult to obtain a PPS resin of such an impurity content as to satisfy the level necessary for a material for coating or sealing electronic parts. As the PPS resin used, for example, one having a melt index <=10,000 (g/10min) as measured according to ASTM D1238-70 is desirable.

Title: Hydraulic driving system
Inventor: MISHIMA TOMONORI
IPC: F15B11/04
Filed: 1979-10-09
Abstract: PURPOSE: To permit the stepless control of an exhaust amount in a range from 0% to 100% by an arrangement wherein a pump with a variable exhaust amount is used as one of two pumps in a driving system of an auxiliary propeller for a ship.  
     CONSTITUTION: With a control valve 22 set at a full power position, a pump 13 is operated at the maximum exhaust and a hydraulic motor 14 rotates at full speed, so that an auxilialy propeller 9 generates the maximum thrust. Next, when the control valve 22 is lowered in its setting, the exhaust of the pump 13 is gradually reduced until its exhaust amount becomes zero. At this point, only a pump 12 is operated and number of revolution of the auxiliary propeller is reduced to 50%. When the setting of the valve 22 is further lowered, the exhaust amount of the pump 13 becomes negative, so that the pump 13 suctions a part of the exhaust from the pump 12 and functions as a motor returning its power to a hydraulic pump driving unit 11. With the valve 22 still further lowered in its setting, the pump 13 is finally brought into the reversed state of -100%. Thus, all of the exhaust amount of the pump 12 is absorbed by the pump 13 and then the hydraulic motor 14 is stopped.
