Title: Method for purifying oil produced by thermal decomposition
Inventor: OKURA TAKAO
IPC: C02F11/10
Filed: 1990-01-29
Abstract: PURPOSE:To obtain high-quality oil free from water and used for the generation of electricity with a diesel by thermally decomposing org. sludge contg. nitrogen to produce char and oil and by neutralizing the oil with an acid. CONSTITUTION:Org. sludge contg. nitrogen is thermally decomposed by heating at 200-600 deg.C under atmospheric pressure or elevated pressure to produce char and oil. This oil is then neutralized with an acid to obtain high-quality oil. Any of inorg. and org. acids may be used as the acid for neutralization but nitric acid, phosphoric acid and sulfuric acid are unsuitable because nitric acid and phosphoric acid contain N and P causing supernutrition, respectively, and sulfuric acid sulfonates the oil. Org. acids are not suitable because BOD is increased. Hydrochloric acid is used as the optimum acid. The purified oil has low kinematic viscosity and a low pour point.

Title: Device for reducing radiation of infrared rays from ship
Inventor: NODA SHIYOUHEI
IPC: B63B15/00
Filed: 1980-02-20
Abstract: PURPOSE: To reduce the intensity of infrared rays emitted outward from a ship, by providing a transparent an infrared ray absorption transparent panel at a distance from the outside surface of the infrared ray making section of the ship such as a chimney.  
     CONSTITUTION: An infrared ray absorption transparent panel 3 is provided at a predetermined distance from the outside surface of the infrared ray emitting section of a ship such as a chimney 2 containing an engine exhaust pipe of high temperature, an upper structure, an upper deck or a broadside plate, the temperature of which is heightened by solar heat. The infrared ray absorption transparent panel 3 is made of acrylic synthetic resin. Since the panel 3 is transparent, visible rays of light with the highest solar radiation energy are transmitted through the panel 3 so that the temperature rise of the panel 3 is kept low. This results in reducing the intensity of infrared rays emitted outward from the ship.

Title: Thermosensitive recording paper
Inventor: TAKEUCHI ENSUKE
IPC: B41M5/337
Filed: 1981-02-16
Abstract: PURPOSE:To improve the stability of a color developed picture against a plasticizer, by employing polyvinylpyrrolidone and zinc oxide as part or the whole of a water-soluble binder and a pigment to be applied for a recording layer of a thermosensitive recording paper. CONSTITUTION:In a thermosensitive recording paper comprising a colorless or light-color developing substance (e.g., leuco dye), an acid substance for thermally developing color thereof (e.g., alpha-naphthol), a water-soluble binder and a pigment, 5-100wt% of the water-soluble binder employs polyvinylpyrrolidone and 5- 100wt% of the pigment zinc oxide to obtain an intended thermosensitive recording paper. This keeps a color developed picture from vanishing or discoloring even in any protrected contact with various plasticizers. Casein and gelatin may be used as the water-soluble binder basides polyvinylpyrrolidone and calcium carbonate, kaolin and the like as the pigment besides zinc oxide.

Title: Pulse generating circuit
Inventor: IWATA AKIHIKO
IPC: H01S3/097
Filed: 1990-01-31
Abstract: PURPOSE:To protect each high-speed switching element by adding a diode and a parallel circuit composed of a resistor and a capacitor between both poles of the high speed switching element of each series stage constituting a serial- parallel circuit. CONSTITUTION:When a diode 12, a capacitor 13 and a resistor 14 are added, a voltage at both ends of the capacitor 13 is Voff when a FET 11 is turned off. Then a voltage Vn is going to rise at a time t0 and the capacitor 13 starts charging through the diode 12 and a voltage at both ends of the capacitor 13 is boosted according to a flowing charge. Thus, the voltage at both ends of the capacitor 13 is gradually boosted and since the voltage applied to the FET 11 is equal to the voltage at both ends of the capacitor 13, till the FET 11 is turned on at a time t1, the voltage is boosted gradually. Thus, even when the on-timing of the FET 11 is delayed, the drain-source voltage is not rapidly boosted and the FET 11 is protected.

Title: Fluid control valve
Inventor: SATOU KOUJI
IPC: F16K7/10
Filed: 1981-02-18
Abstract: PURPOSE:To facilitate a control over a flow rate of fluid by a method wherein a valve body is formed by a closed body of which volume may be varied. CONSTITUTION:Gas or liquid is supplied in a closed valve body 4 by a pressure supplying pipe 5. The closd valve body 4 is expanded to reduce an area of passage of a passage 2 and then a flow rate of the fluid passing through the passage 2 is reduced. When the pressure is continued to be supplied, the valve body 4 completely closes the passage 2 and a flow of the fluid is completely shut off. Then, either gas or liquid contained in the valve body 4 is discharged out through the pressure supplying pipe 5 and the valve body 4 is shrinked, resulting in that an area of the passage is increased and a flow rate of the fluid is increased. When the pressure supplying part of the pressure supplying pipe 5 is provided with means for keeping a supplying pressure constant so as to keep a condition of the volume of the valve body 4 constant, thereby it is possible to vary the flow rate of the fluid in a stepless manner.
