Title: Egr device and vehicle
Inventor: KUSANO HIROKI
IPC: F02M25/07
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To suppress a valve closing delay in a pressure action type EGR valve. SOLUTION: An EGR valve 8 is a negative pressure action valve, in which a valve element 9 is operated by means of a differential pressure between two chambers 11, 12 separated from each other by means of a diaphragm 10. The EGR valve 8 is provided with a pressure switching valve 14 switching a pressure introduced to the first chamber 11 and the second chamber 12. A spool 34 constituting the pressure switching valve 14 is driven interlockingly with an acceleration pedal 28. If the acceleration pedal 28 is actuated by a set operation quantity or more, by which an EGR non-operation area is attained, during the EGR operation, the spool 34 switches pressure to be introduced to the two chambers 11, 12, and the first chamber 11 is opened to the atmosphere, while a negative pressure from a vacuum pump 20 is introduced to the second chamber 12.  Therefore, strong force in the valve closing direction is applied to the valve element 9.

Title: Method and apparatus for measuring rate of water content of grain during drying process
Inventor: ISHITANI YOSHIO
IPC: G01N27/04
Filed: 1979-03-08
Abstract: PURPOSE: To obtain an accurate water content of grain by excluding from a measured value of water content a component corresponding to a rapid increase in the measured value occurring in several seconds after the start of measurement, whereby the fluctuation of measured value due to immature grain mixed in the grain under measurement is excluded from the necessary calculation.  
     CONSTITUTION: This measuring apparatus is provided with a measuring instrument 1 for crushing and clamping grain to measure the resistance thereof and generate a signal which is in inverse proportion to the resistance mentioned above, an integrating circuit 2, a measurement level comparing circuit 3, a measurement interval controlling circuit 4, a measurement frequency counting circuit 5, a measurement flag circuit 6, a 1.75sec. clock pulse generating circuit 7, a two- step cut-off flag circuit 8, a measuring timer circuit 9, an immature rice inhibit circuit 10, and a stop circuit 12. When immature grain is mixed in the grain being subjected to measurement to cause a measurement value to fluctuate greatly, a measurement value after the fluctuation has occurred is excluded to use a measurement value, obtained before the fluctuation has occurred, as an effective value. The water content of the grain is measured within one second after it has been crushed, and again after the grain has been left to be cooled for ten and several seconds. In a case where the second measurement value is higher than the first one by more than around 0.5%, the first measurement value is employed in the calculation of the water content.

Filed: 1993-01-22
Abstract: PURPOSE:To provide a screw, in which a looseness resistant property and fatigue resistant strength are improved, by devising the shape of a ridge. CONSTITUTION:In a ridge, the angle theta1 of a summit part beyond a line L, showing a screw effective diameter, is made smaller than the angle theta2 of a base part. When this male screw is engaged with a female screw, the male screw is contacted with the female screw at the top part of the summit part of the male screw in which the angle theta1 is made small, and this contact becomes near to line contact. Consequently, the top part of the ridge, where stress is concentrated, causes elastic deformation to uniform load distribution, improving a looseness resistant property and fatigue resistant strength.
