Filed: 1987-05-21
Abstract: PURPOSE:To prevent the turbulence of exhaust emission or the like by detecting a physical quantity other than a throttle opening corresponding to a suction air quantity and correcting a prediction value of the suction air quantity according to the detected physical quantity to reduce an error in the prediction value from a real value. CONSTITUTION:A throttle valve 8 of an internal combustion engine 20 is provided with a throttle opening sensor 10. A distributor 40 connected to an ignition plug 38 is provided with a rotational angle sensor 48. Detection signals from the sensors 10 and 48 are input to a control circuit 44. The control circuit 44 computes a present suction air quantity according to each detection signal, and also computes a prediction value of a suction air quantity at a predetermined time elapsed according to the present suction air quantity computed above. Then, a fuel injection quantity is controlled according to the prediction value and an engine speed. At this time, a physical quantity other than the throttle opening corresponding to the suction air quantity, e.g., a suction pressure is detected by a pressure sensor 6, and the prediction value is corrected according to the physical quantity.

Title: Application of electronic component adhering bond
Inventor: ABE SHIGETAKA
IPC: H05K3/30
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for stably applying a bond without scattering of an applied amount even when a syringe is horizontally moved at a high speed when the bond for bonding electronic components is applied to many application points on a substrate one after another while the syringe is horizontally moved over the substrate. SOLUTION: Before a bond is applied on an actual substrate, bond application is carried out on a dummy substrate by a bond applying apparatus correspondingly to the bond application to respective application points on the actual substrate (ST2), and a bond application amount data is optically obtained for each application point (ST4). That application amount data is judged whether it is acceptable or not (ST5), and as to the application point P judged as unacceptable, the application of the bond 1 on the actual substrate is carried out after the application condition is modified based on an application condition adjusting data (ST6). Thus, highly reliable application of the bond 1 with a uniform application amount can be carried out to improve the non-defective rate.

Title: Method for separating optical isomer in sample
Inventor: MORIYAMA HIROYUKI
IPC: B01J20/291
Filed: 1992-04-20
Abstract: PURPOSE:To accurately separate an optical isomer from a sample by feeding the sample to a column for liquid chromatograph/ filled with a filler in which a protein having an optically splitting ability is immobilized. CONSTITUTION:A separation column (a) filled with a filler in which ovomucoid is immobilized is connected to an analysis column (b) filled with the same filler. After about 20mul of a sample solution prepared by dissolving about 100g of a mixture of propranolol and ceramics in a human blood serum is fed to the column (a) at a rate of about 1ml/min and a cleaning solution is fed to the column (a) for about three minutes, an eluent is fed to the column (a). These operations are repeated, for example, five times. Then, by switching the eluent from the column (a) to the column (b), propranolol is fed to the column (b). The optical isomer eluted from the column (b) is measured with a fluorescence detector (e) Therefore, even when a sample contains a protein, an optical isomer contained in the sample can be separated and analyzed. Therefore, no pre- processing is required for removing the protein and the occurrence of a measurement error associated with the pre-processing can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To provide a single operation type operation mechanism capable of ON operation as it is by constituting the operation mechanism so as to become a quickly closing mechanism by contacting a contact point at a high speed when going over the dead center when the contact point returns to an ON state from an OFF state as well as to become a mechanism for returning the operation part to an ordinary OFF state when the contact point is turned off by an abnormal current. SOLUTION: In ordinary contact point opening/closing, a movable contact point 11 goes over the dead center by links 2, 3, 6 to 8 having the dead center by rollingly operating the operation part 204 to the ON side and the OFF side. Afterwards, the movable contact point 11 contacts with a fixed contact point 12 at a high speed after idly traveling without depending on an operation speed of the operation part 204 since force of springs 4, 5, 9, 14 is added in the rolling direction.  After the movable contact point 11 is opened by an abnormal current, the movable contact point 11 returns to an OFF state by the action of the respective links and the springs, so that the operation part 204 is reset up to an OFF position to thereby obtain a single operation type just reset system contact point switch mechanism requiring only to turn on the operation part 204 as it is when the movable contact point 11 is closed again.

Abstract: PURPOSE: To surely prevent water at a flow outlet side from reversely flowing to a flow inlet side, by arranging a float in a valve chamber having both openings of the flow inlet and outlet and an opening of a valve hole at its upper part communicated to a vent port.  
     CONSTITUTION: When a feed water pump 18 is driven to perform a pump up operation, air in a feed water pipe line passes through a valve hole 11 of an air valve 21 and is discharged to the outside. When water flows coming into a valve chamber 5 from an inlet passage 6, a float 17 floats with the water, the external surface of a sphere is seated on a valve seat 12 to completely close the valve hole 11. When the feed water pump 18 is stopped, a downflow is caused in a main pipe 19, and waters in transverse pipings 20', 20, 20" are pulled back toward the side of the main pipe 19. At this time, the water in the valve chamber 5 of the air valve 21 reversely flows to the side of the inlet passage 6 to lower the pressure in the valve chamber 5, then the float 17 is detached from the valve seat 12 to open the valve hole 11, thus the air at the side of a vent port 10 is allowed to pass the valve hole 11 and sucked into the valve chamber 5.
