Title: Accumulated fuel injection system for diesel internal combustion engine
Inventor: SAKAMOTO YASUJI
IPC: F02M55/02
Filed: 1999-01-06
Abstract: PROBLEM TO BE SOLVED: To provide an injection characteristic having good responsiveness, improve an output of a diesel engine, improve fuel consumption, and reduce harmful component of exhaust gas by arranging an accumulating chamber on a downstream side from a common rail for accumulating pressure of fuel supplied to a nozzle holder for fuel injection arranged per cylinder. SOLUTION: High pressure fuel is supplied from a high pressure supplying pump 3 to a common rail 1 for accumulating pressure of fuel supplied to a nozzle holder 2 for fuel injection arranged per cylinder of a diesel internal combustion engine. In this case, an auxiliary accumulator 6-1 is arranged between a fuel distribution pipe 4 arranged downstream of the common rail 1 and the nozzle holder 2. The auxiliary accumulator 6-1 is formed so as to have an auxiliary accumulating chamber having a capacity of 3 to 20 times of the maximum injection rate of one time in the inside of the auxiliary accumulator 6-1. It is thus possible to improve fuel injection responsiveness without lengthening the common rail 1 and the nozzle holder 2 and enlarging an inner diameter, it is also possible to provide a correct injection characteristic so as to improve fuel consumption and the like.

Title: Spectroscope of cylindrical lens type
Inventor: HASUMI RITSUO
IPC: G01J3/02
Filed: 1979-01-08
Abstract: PURPOSE:To obtain a thin and miniature spectroscope by arranging a cylindrical lens at the incident mouth and projecting mouth of a spectroscope and by converting only vertical light mutually from a spot light source to a parallel beam. CONSTITUTION:On substrate 1, diffraction lattice 2, cylindrical lens 3 of long focal distance and cylindrical lens 5 of short focal distance connecting to optical fiber 4 are arranged perpendicularly. Light 6 only in the vertical direction is converted into parallel beams. Since optical fiber 4 is on the focus of lens 3, horizontal beams are converted into parallel beams by lens 3. Parallel light beams long horizontally and short vertically strike diffraction lattice 2. On the other hand, diffracted light 7 is focused by lens 3 and vertically by lens 5 before being coupled with optical fiber 4, wavelength by wavelength. A decrease in the focal distance of lens 5 reduces the vertical spread between light 6 and diffracted light 7. Therefore, a thin and miniature spectroscope for light communication can be realized.

Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To easily form desired beams of two frequencies by combining a pair of reflectors shaped like V by bending plane reflectors for reflecting or selectively transmitting radio waves according to the frequencies of the radio waves into a prescribed shape by making their open angles different. SOLUTION: This antenna device is constituted of a V-shaped reflector 1 constituted of plane reflectors 11 and 12 crossing each other along a straight line 4 and a V-shaped reflector 2 constituted of frequency selecting plane plates 21 and 22 respectively formed by bending a plane metallic plate, and the reflectors 1 and 2 have a common symmetrical face 3 including the straight line 4. Radio waves radiated from a linear primary radiator 51 on the symmetrical face 3 are transmitted through the reflector 2, and reflected on the reflector 1, and radiated to a space in the direction 61. Radio waves radiated from a linear primary radiator 52 are reflected on the reflector 2, and radiated to a space in the same direction 62 as the direction 61.  In this case, the radiative shape is controlled according to the width, height, and open angle of each reflector and the distance of the radiator from the V-shaped corner. Therefore, those parameters are independently selected for each reflector so that desired beam patterns can be obtained.

Title: Separating method by fluidized crystallization utilizing high pressure
Inventor: MORITOKI MASATO
IPC: B01D9/02
Filed: 1978-01-12
Abstract: PURPOSE: To perform crystallization effectively from a mixt. in which solidification hardly proceeds, by fluidizing the mixt. consisting of two or more components, specific components of which  are in a supercooled state at a high press., to form crystal nuclei of the specific components, and  by promoting the growth and incease of the crystals without lowering the temp.   
     CONSTITUTION: Raw liq. (a mixt.) pressurized by a press. intensifier 1 is fed in the direction of  an arrow A to a crystal nucleus generator 2, and further to a separating vessel 3. In this case,  crystal nuclei generated in the nucleus generator 2 further grow and increase in the vessel 3, and  the solid are separated from the liq. by filters 14. The crystal formation in the above-described  crystallization is accelerated through fluidization, and the solidification is promoted rather by  temp. rise under adiabatic conditions. Mother liquor having passed through the filters 14 is  delivered through pipes 8, 9 and press. control valves 12, 13 respectively to a waste soln. tank 4.  When the solid/liq. separation by the filters 14 becomes difficult through continuation of crystallization and separation, the mother liquor is further separated either by compressing it into the  vessel 3 by higher press., or by decreasing the press. gradually so as to melt a portion of the  crystal and to separate the liq. phase successively, purifying effectively the specific components.
