Title: Artificial whirlwind generation mechanism and application method
Inventor: MATSUI SHIGEO
IPC: F24F7/06
Filed: 1988-11-01
Abstract: PURPOSE:To reduce production cost and running cost by introducing side wall to both ends of a spiral-shaped wall formed so that its surface may be gradually oriented to the center, a suction port so that it may be located to the axial central part under spiral state to said side wall and constituting the suction port with a spiral-shaped basic end section, its tip section and side wall. CONSTITUTION:When a suction fan installed on the down-stream side of a suction duct 3, opening dampers 15 as specified, an air A contaminated by dust or dirt generated on a work table 1 is absorbed from an air intake port 13 for an exhaust air duct 2. The air A flows along a front wall 10, and further flows along a spiral-shaped wall 12 communicating with the front wall 10, which produces a swirling air current. As this swirling air current is absorbed by the absorption duct 3, negative pressure sections E1 and E2 are generated in this air current respectively so that artificial whirlwinds H1 and H2 may be formed. The artificial whirlwinds H1 and H2 discharge the air A contaminated on the work table 1 at a uniform velocity along the entire surface of the intake port 13 from the intake duct 3.

Title: Fuel supply device of internal combustion engine
Inventor: NAKAJIMA KAZUSHI
IPC: F02D41/06
Filed: 1992-10-15
Abstract: PURPOSE:To eliminate a return piping by surely performing discharge of vapor gas from an injector. CONSTITUTION:Fuel inside a fuel tank is pressure-fed to a delivery pipe 1 by a fuel pump, and the fuel supplied from the delivery pipe 1 is injected to an engine by an injector 2. At least one of respective connectors 1a for distributing fuel from the delivery pipe 1 to the respective injectors is opened on the top part inside the delivery pipe 1. A fuel pump 3 branched from a fuel piping 6 upstream from the delivery pipe 1 is set above the delivery pipe 1, and the fuel pump 3 is communicated with the delivery pipe 1 through a throttle 4. Consequently, after the vapor gas is stored in the fuel pump 3, it is introduced into the delivery pipe 1 through the throttle 4 little by little, and thereby rapidly discharged via the connectors 1a from the injector 2.

Title: Pantagraph type disconnector
Inventor: KATO SATORU
IPC: H01H31/36
Filed: 1991-09-27
Abstract: PURPOSE:To precisely measure the current running in a disconnector in a pantagraph type disconnector. CONSTITUTION:When a current is sent from an external terminal 24 to conductive arms 23a, 23b, the current flows from the conductive arms 23a, 23b to an external conductor through arm driving shafts 22a, 22b, third conductive paths 41a, 41b, second conductive paths 38a, 38b, and terminals 27a, 27b. Although the arm driving shafts 22a, 22b make also contact with a box 25, the current never flow to the outside through the box 25 since the box 25 is electrically insulated from the first conductive paths 28a, 28b and terminals 27a, 27b which are the passages for current. Thus, all the current flowing into the conductive arms 23a, 23b flows to the second conductive paths 38a, 38b, and an optical CT detects the current value around the second conductive paths 38a, 38b.

IPC: G02B6/32
Filed: 1988-11-02
Abstract: PURPOSE:To efficiently produce the optical circuit parts having stable quality without requiring special jigs by integrating and housing an optical fiber and lens in the 2nd sleeve having elasticity. CONSTITUTION:The 2nd sleeve 7 is interposed into the 1st sleeve 2. A ferrule 5 consisting of ceramics, etc., inserted with the optical fiber 4 and a spherical lens 6 are housed into this 2nd sleeve 7. The 2nd sleeve 7 has elastic force if the sleeve 7 is previously worked to the inside diameter slightly smaller than the outside diameter of the ferrule 5 and the lens 6 when stresses are zero. Misregistration does not, therefore, arise unless a particularly large external force is exerted to the 2nd sleeve if the relative positions of the ferrule 5 and the lens 6 are determined and set within this sleeve. The optical circuit parts having the characteristics of the stable optical axis are efficiency produced in this way without requiring the special jigs.

Title: Liquefied gas pouring nozzle
Inventor: YAMADA MORIO
IPC: F17C9/00
Filed: 1985-12-12
Abstract: PURPOSE:To prevent the scattering of liquefied gas and to get a pouring nozzle giving little change in pouring quantity by forming, in a liquefied gas pouring nozzle, plural hollow chambers, upper parts of which facing a liquefied gas tank are opened and lower parts of which are closed in a taper form. CONSTITUTION:A liquefied gas pouring nozzle 6 is made of porous material and also has plural hollow chambers 7 whose upper parts facing a liquefied gas tank 1 are opened and whose lower parts are closed in a taper form. For this reason, falling liquefied gas is poured and scattered in hollow chambers 7 and thereby the falling pressure decreases and the falling speed becomes slow because the liquefied gas oozes from the porous wall of the hollow chamber 7, therefore it is made possible to prevent the liquefied gas from causing collective flow resulting in scattering or causing a change in falling quantity.
