Filed: 1984-02-25
Abstract: PURPOSE:To make it possible to simply decompose the nitrogen compound in water with good efficiency even if a suspended substance is contained in water and to reduce maintenance work, by decomposing the nitrogen compound to a nitrate ion by oxidation by bringing specimen water into contact with ozone under an alkaline condition. CONSTITUTION:An apparatus is constituted of a specimen water sampling part A, an alkali injection part B, a reaction part C and an ozone generation part D and a specimen water containing a nitrogen compound is collected in a reaction tank 4 through a sampling tube 1 while an aqueous alkali solution is added to the reaction tank 4 from an alkali tank 7. Subsequently, ozone is sent into the reaction tank 4 from an ozone generator 11 through a ball diffuser 6 and excessive ozone is discharged into the open air through a change-over switch 13 while decomposed to oxygen by an waste ozone decomposition device 15 and, after a difinite reaction time, ozone is guided to the decomposition device 15 by changing over a change-over cock 12 and decomposed therein. By this method, the nitrogen compound can be decomposed to a nitrate ion by oxidation.

Title: Ink-jet recording system
Inventor: ARAKAWA JIYUNICHI
IPC: B41J2/21
Filed: 1983-03-04
Abstract: PURPOSE:To avoid erroneous capping and suction restoring operations by installing a false operation prevention lever making unavailable for operation capping or suction restoring apparatus in case when a recording head is not located in the home position. CONSTITUTION:In case when a lever 5 is pulled in the direction C represented by an arrow under a condition that, a recording head 2 is located in a position 2' which is deviated from the home position, a false operation prevention lever 12 stands contacting a stopper 4c by an energizing force of a coil spring 17 and its downward motion by pressure becomes unavailable by interruption of a convex part D of lever 5 against the lever 12. Thus, when the head 2 is found outside the home position, the prevention lever 12 is inserted between stopper 4c and operation lever 5 under a force of coil spring 17, stopping the downward motion under pressure of the lever 5. In this way, capping and suction restoring operation can be prevented, when the recording head 2 is located outside the home position.

IPC: H02K3/38
Filed: 1988-02-17
Abstract: PURPOSE:To improve the reliability of insulation by integrally molding a conduction cable. CONSTITUTION:The conductor of a coil employs a flat aluminum conductor, and a winding 4 is formed by winding a glass tape thereon. Its end is bent perpendicularly as a connecting end 4a, and connected to the end 3a of a lead conductor 3 by engaging it with a conductor sleeve 6. In this case, an electric field alleviation bell-mouth 7 is mounted on the outer periphery of the end of the cable 3 to be connected to the shielding layer of the cable 3. A coil is inserted into a metal mold except the cable 3, molded to form a coil 1, and formed with a conical swell 5 of an insulator at the root of the cable 3. Thus, since the cable 3 with a shielding for conduction is integrally molded, a conduction cable is not separately required, and its insulating characteristic can be improved.
