Title: Valve for drawing back fluid while closing
Inventor: TOMITA ICHIO
IPC: B05B7/08
Filed: 1993-09-14
Abstract: A valve comprises a fluid passage formed in a valve body (51), and having a valve seat (55), a smaller diameter portion (56) extending downstream from the valve seat (55), and a larger diameter portion (57) extending downstream from the smaller diameter portion (56). A valve element (58) is movable between the valve seat (55) and a position within the larger diameter portion (57). During closing, the valve element (58) moves toward the valve seat (55). When the valve element (58) moves within the smaller diameter portion (56), fluid is drawn back due to the pumping effect of the valve element (58) before the element (58) finally reaches the valve seat (55) and closes the valve. The element may be moved by a piston 61 movable in a cylinder 60, or by means of a pressure diaphragm (Fig 5, not shown). The valve can be used in an electrostatic paint sprayer, which is driven by an air motor (Fig 2, not shown). <IMAGE>

Title: Fail-safe system of an automatic driving system for a motor vehicle
Inventor: NAGAI MASAAKI
IPC: G01S11/12
Filed: 1994-01-26
Abstract: An automatic driving system for a motor vehicle has a main actuator M for operating a main throttle valve 7, an auxiliary actuator 10 for operating an auxiliary throttle valve 8, and sensors for detecting driving conditions of the motor vehicle. A failure of the automatic driving system causes the main and auxiliary actuators to close the main and auxiliary throttle valves. Thereafter, automatic drive is deselected by the driver where upon the auxiliary throttle is fully opened and the main throttle reverts to manual control. In normal driving, the automatic driving system may respond to the distance of the vehicle in front and the auxiliary throttle may impose traction control. The detection of failure may be in response to anomalous acceleration, throttle position, intake air quantity or traction control system operation. <IMAGE>

Title: Deuteron corpuscle collider
Inventor: STEWARDSON KIM ALAN
Filed: 1994-12-02
Abstract: The machine provides a means of achieving nuclear fusion through the collision of particle beams. A deuteron beam is attracted to a negatively charged palladium coated gauze (1). The polarity of the gauze is switched to positive causing the emission of deuteron packets toward a second negatively charged electrode (2) the polarity of which alternates oppositely and simultaneously with the palladium electrode. This procedure produces packets of deuterium ions which are propelled into an accelerator, (3) energising them. They are then introduced into the collision chamber achieving a high beam density being compressed by two aligned electromagnets (5 and 6) which channel the beam along the corner of a bracket (4) made from positive semiconductor material, a substance resistant to friction and penetration from fast moving nuclear particles. <IMAGE>
