Inventor: SATOMURA MASATO
IPC: B41M5/20
Filed: 1983-04-12
Abstract: PURPOSE:To enhance stability in air of a dye precursor for black color forming recording and fastness of a dye formed therefrom against light, moisture or the like, by using a fluoran derivative having an arylamino group at 2-position, a long chain alkyl group at 3-position and an amine residue at 6-position. CONSTITUTION:A fluoran derivative having an arylamino group at 2-position of the fluoran ring, a long-chain alkyl group at 3-position and an amine residue at 6-position. A specified fluoran derivative having a long-chain alkyl group at 3- position of the fluoran ring is markedly water-insoluble and has a low melting point. Further, when an arylamino group, particularly, an anilino group, or a p- methyl or p-chloroanilino group is introduced to the 2-position of the fluoran ring, the fluoran derivative forms a color of pure black hue through interaction with a color developer having a phenolic hydroxyl group. Such a fluoran derivative is a colorless or light-colored crystal, is markedly hydrophobic, is highly soluble in organic solvents, and rapidly forms a black color upon contact with an electron-receptive substance. The developed dye is remarkably stable, and is excellent in fastness against discoloration or decoloration when being exposed to light, heat or moisture for a long period of time.

Title: Float valve
Inventor: YOKOYAMA TAKESHI
IPC: F16T1/24
Filed: 1989-03-15
Abstract: PURPOSE:To enable the increase of a valve opening lift of a valve body without enlarging a valve chamber by driving a first and a second levers with the displacement of a float, and moving a supporting point of the first lever, to which a valve body for switching a valve port is attached, to the side separated from the valve port. CONSTITUTION:When the condensate and the steam are flowed into a valve chamber 4 and the condensate is separated to be settled in the lower and the steam is separated to be settled in the upper, a float 11 is floated with the rise of the liquid surface in the valve chamber 4 to abut on a first lever 13 and a side wall 16. When the float is further raised from the liquid surface, the buoyancy of the float 11 is enlarged to work to the lever 13 as a wedging force, and the lever 13 is rotated in the valve opening direction, using a supporting point 14 positioned in a valve port 9 side in a long hole 3 as a supporting point, and abuts on one end of a second lever 20 to rotate the lever 20 and rotates further. At this stage, the other end of the lever 20 displaces the supporting point 14 of the lever 13 to the side separated from the valve port 9 in the long hole 3 while the lever 29 is being rotated. The condensation in the valve chamber 4 is thereby exhausted from the valve port 9 to an outlet 7, and when the liquid surface lowers, the float 11 falls down and a valve body 15 seals the valve port 9 to prevent the exhaust of the steam.

Title: Air-conditioner for electrically driven vehicle
IPC: B60H1/22
Filed: 1992-03-23
Abstract: PURPOSE:To prevent the deterioration of the heating efficiency of the heat pump by preventing the disturbance of the air heat exchange due to development of the icing of the air heat exchanger outside the vehicle. CONSTITUTION:When the heat pump is warmed, an air heat exchanger 2 outside a cabin becomes low temperature, and the water content in the air is frosted and frozen, leading to the condition where no heat exchange with the air becomes possible. A heating unit 8 consisting of an electric heater is provided in order to prevent this phenomenon. When the vehicle is stopped, development of freezing can be prevented more effectively than the condition where the vehicle wind velocity is available during traveling by warming the heat exchanger 2 by this heating unit 8. When the vehicle is stopped for charging the battery, the method to start the heating unit by the external power source is effective. In addition, the heat exchanger 2 can be heated by driving the heat pump heating/cooling air-conditioner in the defrosting mode by the reverse cycle by the external power source.
