Title: Oil separating apparatus
Inventor: HORIKAWA ISAO
IPC: B01D17/00
Filed: 1978-10-20
Abstract: PURPOSE: To make assembly and disassembly of each separating chamber easy and to enlarge the adsorption area of oil by dividing box case into a treating chamber in the upper part and a clear water residence chamber in the lower part by a first partition plate and dividing the treating chamber into a running water rectifier chamber and an oil recovery chamber by a second partition plate.  
     CONSTITUTION: Oil-containing waste water which flowed into a running water rectifier chamber 1F is passed, while rectifying in a rectifier tube 1F', through an ascending crude particle separating chamber 1L, a rectifier plate 10 and an descending fine separation chamber 1N, thereby oil is separated from water. Oil is stored in an oil recovery chamber 1G and recovered through a recovery port 1G. Water is discharged from a clear water residence chamber through a water level stabilization chamber 1P and a drain port 1R. According to this process, oil is easy to separate and rise, because the flow rate in circumferential part is slow in comparison with the flow rate in the central part from the nature of central chamber tubes.

Abstract: PURPOSE:To make the movement of a throttle lever smooth by interlockedly connecting the driving operation part of an accelerator pump to a speed control lever so as to be capable of driving operation, so that the frictional resistance of a pump driving system does not act as a disturbance factor of a governor. CONSTITUTION:When a speed-change lever 5 is turned onto the high-speed side so as to be quickly accelerated, in interlock with this, the driving operation part 11 of an acclerator pump 8 is driven to supply the fuel for acceleration to a mixture passing part 7 from the accelerator pump 8, and the acceleration of an engine 1 is carried out. As usual, when the speed-change lever 5 is held in a given position, even if a governor 4 is operated by a load fluctuation to move a throttle lever 3, the accelerator pump 8 is not driven. Thus, the fric tional resistance of a pump driving system does not act as a disturbance factor of the governor 4, and no excess fuel is supplied to the mixture passing part 7 from the accelerator pump 8 in interlock with the movement of the throttle lever 3.

Title: Flat display screen anode having protective ring
Inventor: MOUGIN STEPHANE
IPC: G09F9/30
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To eliminate any spark taking place on a screen peripheral edge by surrounding an active range by means of one track for collecting the re- discharged secondary electrons and separating the active range from the peripheral edge of the active range by means of an interval within the insulating material of the track. SOLUTION: An insulation interval 22 must be made sufficiently large for avoiding any electric arc taking place between an active range 20 and a collective link 21. However, the interval 22 is made as narrow as possible so as to avoid any expansion of a positive electric load range within this interval. The width of the interval 22 is made smaller than the average distance liable to be progressed by those secondary electrons discharged from the surface of this interval, with provision of allowance by a bias voltage. Thereby, the entire secondary electrons re-discharged from the insulating material 22 are collected by material 21. Accordingly, such a phenomenon as propagation of the secondary electrons to a sealed joint between an anode and a cathode. Furthermore, by having the ring 21 biased, the corresponding electric load can be eliminated.
