Title: Transfer material carrying member and image forming device having the member
Inventor: HAYASHI YASUKO
IPC: G03G15/16
Filed: 1996-02-08
Abstract: PURPOSE: To provide a transfer material carrying member having high transfer efficiency and excellent electrical leakage resistance by forming the member in such a manner that the ratio of the specific dielectric constant possessed by the front surface layer of the transfer material carrying member and the specific dielectric constant possessed by layers exclusive of the front surface layer satisfy a specific relation. CONSTITUTION: This transfer material carrying member 11 is so formed that the ratio (E1/E2) of the specific dielectric constant (E1) possessed by the front surface layer 11a of the member and the specific dielectric constant (E2) possessed by the layers (11b) exclusive of the front surface layer satisfies the equation 0.02<=(E1/E2)<=0.7. Namely, E1/E2 is 0.02 to 0.7 and is more particularly preferably 0.05 to 0.5 and is further preferably 0.05 to 0.4. The charges of transfer current are liable to leak and such leakage is the cause for an image drop- out if E1/E2 is larger than 0.7. On the other hand, the charges are accumulated in the transfer material carrying member 11 by the current discharged at the time of transfer if E1/E2 is smaller than 0.02. The toner images are no longer transferred if the repetitive copying is executed.

Title: Water purifier in tank
Inventor: EGUCHI SAKAE
IPC: C02F1/28
Filed: 1981-02-17
Abstract: PURPOSE: To improve the purification efficiency of water by supporting a biscuit made by mixing powders of acid clay, a combustible material and a low grade radioactive material of a range permissible to man and sintering the mixture to a porous adsorbent body in such a way that nearly the entire surface thereof is exposed to water.  
     CONSTITUTION: Powders of 60% acid clay, 10% combustible material such as sawdust, and 30% uranium oxide ore of a low grade excluded from nuclear materials within a range permissible to man are mixed and the mixture is sintered at 600°C, whereby a sponge-like porous adsorbing biscuit body 1 is obtained. This biscuit 1 is molded to a flat plate or disc shape, and the top and bottom surfaces thereof are formed to rough surfaces having ruggedness. A supporting base 2 is sunk in a water tank 8 provided to the top end of a steel tower 7, and is supported in water 9 by bringing its legs 6 in contact with the bottom surface. Then, when water flows through the inside of the sponge-like small holes, the water 9 is purified by the radioactivity by the α-rays and β-rays generated from the radioactive material.

Title: Method for reducing copper content of slag for refining crude copper
Inventor: YAMAMOTO SATOMI
IPC: C22B15/14
Filed: 1984-02-13
Abstract: PURPOSE:To reduce the loss of copper during refining and to improve the refining stage by blowing a subsidiary material such as an alkaline earth metallic chloride into crude copper contg. a specified percentage of oxygen with an oxidizing gas. CONSTITUTION:A subsidiary material such as CaCl2 as an alkaline earth metallic chloride or a mixture of CaCl2 with CaO as an alkaline earth metallic oxide is blown into molten crude copper with an oxidizing gas such as air or oxygen- enriched air at >=30cm depth. The blown material is melted as once at the temp. of the crude copper to form finely divided slag. Since the subsidiary material is blown into the crude copper having a low O content with the oxidizing gas, the copper content of slag on the crude copper approaches equilibrium with the low-O crude copper and lowers. Accordingly, refining is carried out in a state in which the copper content of the slag is kept low. By this method, the loss of copper is reduced, and the refining stage can be improved to reduce the loss of energy.

Filed: 1995-01-19
Abstract: PURPOSE: To eliminate a condition in which releasing agent is collected at a tip of a separated claw and stains are created on a transfer material by the agent by providing a means which blows air on the tip of the separated claw. CONSTITUTION: A nozzle 7 which jets air is arranged at a proper position where the running of a transfer material to be conveyed is not interrupted above a separated claw 4. Consequently, it blows off releasing agent which is collected at a part where the separated claw 4 comes into contact with a pressurizing roller 3 so that the transfer material is not stained by the collected releasing agent. Since the blown off releasing agent flows downwardly along a surface of the pressurizing roller 3 from a side of the separated claw 4, a cleaner such as sponge, felt, etc., may be provided at a proper place as required to remove the agent. The blowing off of air on a tip of the separated claw 4 may be performed at all times, but it is preferable to blow air intermittently by setting a timing. Preferably, the quantity of air is set to approximately 0.005 to 0.03m<2> /sec per cm<2> .

Title: Method of fuel injection for electronically controlled engine
Inventor: HORII KINGO
IPC: F02D41/12
Filed: 1982-02-19
Abstract: PURPOSE:To suppress an impact just after the initiation of deceleration, by providing two kinds of the characteristics of increasing fuel amount at deceleration corresponding to the speed of a vehicle or an engine so that the amount of fuel injection is calculated. CONSTITUTION:By arranging such that the larger the deceleration of a vehicle, the quicker the the amount of basic fuel injection is reduced, the characteristic  of increasing amount ratio C1 is increased for making gentle the deceleration of  torque generated by an engine. Further, since the feeling of impact experienced  in a low speed vehicle or engine is more intense than that experienced in a high  speed vehicle or engine, the increasing amount ratio C1 at deceleration is made  large by selecting the second characteristic of increasing amount ratio, thereby  the impact is relaxed.
