Title: Method for manufacturing ferrite of hexagonal system
Inventor: GUNTAA MAIRU
IPC: H01F1/11
Filed: 1989-02-06
Abstract: PURPOSE: To stably manufacture hexagonal system ferrite having excellent characteristics as a magnetic material by heat-treating a homogeneous mixture of a metallic oxide for forming ferrite and a glass forming material and then dissolving and removing glass components of a matrix by an acid of specific composition.  
     CONSTITUTION: The metallic oxide for forming ferrite is melted together with the glass forming material such as a borate, a phosphate and a silicate to be amorphous and glassy and then is sprayed. After the glassy material pulverized by spraying is heat-treated, for example, at 750°C for 2 hours, the glass components of the matrix are dissolved and removed by nitric acid, hydrochloric acid, formic acid, etc., to isolate hexagonal system ferrite particles from the matrix. In this case, an acid substantially having chemical oxygen rate of <1 mole per 1 mole of the acid is used for the acid using for dissolving the matrix. Thus the hexagonal system ferrite as the magnetic material is manufactured at a low cost.

Title: Direct injection type internal combustion engine
Inventor: ENDO HIROYUKI
IPC: F02B23/10
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To obtain high-temperature high-pressure plasma so as to improve the durability of an electrode and the like of a plasma jet spark plug and ensure rapid ignition by providing a fuel converted gas feeder for gasifying liquid fuel to supply it to a cavity of the plasma spark plug. SOLUTION: A plasma spark plug 2 is fixed on a cylinder head 15 by appropriately setting its position relation with a fuel injection valve 1 from the relation between fuel injection and plasma gas jet. Since the interior of a catalyst chamber 23 is previously heated to the catalyst activating temperature by a heating device such as an electric heating coil, fuel gasifying reaction is generated so as to generate fuel converted gas. When high voltage is applied to a center electrode 6, discharge spark is generated, and the fuel converted gas led into a cavity 7 is put in a high-temperature high-pressure plasma state. The fuel converted gas put in the plasma state is jetted as high speed jet 12 into a combustion chamber 20 from an orifice 11. Fuel spray 14 is thereby ignited so as to attain positive ignition and combustion.

Abstract: PROBLEM TO BE SOLVED: To avoid a defective image such as an offset phenomenon, complication of temperature control, and decrease in copying productivity by making a correction to a preset temperature to be lowered by a driving control means according to a count value of an image forming operation. SOLUTION: A thermistor 3 for detecting a temperature of a fixing roller and a counting means 7 are connected to a control circuit 2. After an electric power source is supplied, it is firstly judged whether or not an image forming device is 'under image forming operation', and in the case of 'YES', 'time count up' is carried out, and when a 'timer value' by this 'time count up' is equal to 100 seconds or more a temperature of a fixing heater is controlled to be set to a temperature lowered by 'about 5 deg.C'. The 'timer' here shows a count of an image forming operation time, and the counting (numeration) of the timer value is carried out by a counting means 7. After that, if the 'timer value' is '150 seconds or larger', the temperature of the fixing heater is further controlled to be set to a temperature lowered by 'about 5 deg.C'.

IPC: B29B15/14
Filed: 1985-02-14
Abstract: PURPOSE:To allow a base to be well impregnated with a resin with the resin adhered to the fibers of the base, by replacing the air present between the fibers of the base with a gas of an inorganic compound capable of being dissolved in the resin liquid. CONSTITUTION:After the air present between the fibers of a base is replaced with a gas of an inorganic compound capable of being dissolved in a resin liquid, the base is impregnated with the resin liquid. For the impregnation, while a replacing container 3 having a gas inlet 1 and a gas outlet 2 is being loaded with the gas, the base 6 is passed through this replacing container 3 so that the base 6 may come in contact with the gas of an inorganic compound. When then the base is immersed in the resin liquid 4, the gas that replaced the air present between the fibers and threads of the base dissolves in the resin liquid 4, resulting in a vacuum state between the fibers and threads, thus the resin goes between the fibers and threads, the when all the gas in the base dissolves into the resin liquid, the resin penetrates to adhere to the fibers and threads.
